Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for a computer user to interact with a computer, and more particularly to an input interpreter for interpreting a command input from the user.

[0002]

2. Description of the Related Art In order for a user to interact with a computer to give an instruction, it is necessary for the user to achieve the user's purpose by transmitting only the purpose and minimum necessary information. The method of instructing the user needs to be a simple input in which keywords are freely listed. In addition, for such free-form input, the computer side needs to supplement missing information when there is a defect in the instruction, and to interpret the same input differently depending on the user's situation, One of the conventional techniques for realizing free input is Japanese Patent Laid-Open No. 62-
No. 290919, "Command execution method" is known. The configuration is shown in FIG.

The command name from the command input section 23,
The command interpreting unit 26 interprets the parameters related to the command from the parameter input unit 24, and defines the correspondence between the command and the plurality of functions of the command according to the number of commands and the number of the parameters (designating method). By collating with the defined definition of the command operation procedure definition unit 25, the function of the corresponding command is read and executed by the command function execution unit 27. As a result, the person who inputs the command can execute the command by the method of specifying the parameter that is easy to use.

[0004]

However, in the conventional method, it is necessary to separate the command and the parameter at the time of input, and there is little information for interpreting the situation of the user. Different interpretations could not be made depending on the user's situation.

In order to solve the above problems, an object of the present invention is to interpret the input information according to the user's situation and to complement the missing information in a free format which has not been possible in the past and with a minimum required. An object of the present invention is to provide an input interpreting device that achieves a user's purpose of use only by inputting information.

[0006]

A first input interpreting device of the present invention comprises an input means for inputting a command and instruction consisting of a combination of keywords from a user, an output means for making a response to the user, and A registered word dictionary in which a command corresponding to a keyword is registered, a command execution means for executing the command, a history database for storing a history of the input means, the output means, and the command execution means, and the history of the keyword And a message format knowledge describing the correspondence between the command and the parameter of the command, the registered word dictionary, the message format knowledge and the history search means to interpret the command instruction, The command to be executed and the corresponding parameter to the command executing means, And having a message management / interpreting means for outputting the execution result of the line means to the output means.

Further, the second input interpreting apparatus of the present invention is, with respect to the first input interpreting apparatus, a parameter dictionary composed of a correspondence table showing a correspondence between the keyword and a set of attribute names of the keyword. Receiving a keyword from the history search means, searching the parameter dictionary, outputting the attribute name of the keyword to the history search means, and when the history of the history database is added, the added history is used. And history inference means for updating the parameter dictionary.

The third input interpreting apparatus of the present invention corresponds to the input means for inputting a command instruction consisting of a combination of keywords from the user, the output means for responding to the user, and the keyword. A registered word dictionary in which commands are registered, command execution means for executing the commands, message format knowledge describing the correspondence between the commands and the parameters of the commands, and first information other than the information input by the user. External information acquisition means to collect, an event dictionary defining second information to be collected with respect to the command instruction, first information from the external information acquisition means using the second information, and the input History of the means, the output means, and the command execution means,
Event data generating means for grouping the first information and registering it as event data, a history database for storing the event data, and a search expression describing information for converting the command instruction into a history search expression or an event-related expression. A dictionary and an event-related extraction unit that converts the event-related expression into the history search expression by searching the history database; and the history search expression or the event-related expression using the search instruction dictionary for the command instruction. Conversion to an expression, and if there is the event-related expression, output to the event-related extraction means to obtain the history search expression, and search expression conversion means for searching the history database using the history search expression; Using the registered word dictionary, the message format knowledge, and the search expression conversion means Message management / interpretation means for interpreting the command instruction, transmitting the corresponding command and the corresponding parameter to the command execution means, and outputting the execution result of the command execution means to the output means. .

The exchanged messages follow the format described in the message format knowledge 3. In the history database 8, all the messages exchanged through the message management / interpretation means 1 are recorded through the history recording means 6. When the history database 8 is rewritten, the situation judging means 4 searches the situation knowledge 5, and the message managing / interpreting means 1 transmits the message addressed to the output means 11 and the command executing means 9 in accordance with the knowledge execution unit that satisfies the condition. To request. If there are a plurality of interpretation methods for the input from the user and the message management / interpretation means 1 cannot determine which interpretation should be performed, the message management / interpretation means 1 queries the situation determination means 4. The situation judging means 4 determines the most probable interpretation according to the situation knowledge 5 and sends a reply to the message managing / interpreting means 1.

From the above, in the present invention, a simple instruction from the user (by a free list of keywords)
In order to return the response intended by the user, if there is ambiguity in the instruction or if there is missing information,
It can be interpreted according to the user's situation. This allows
It is possible to reduce the burden on the user by reducing the time and effort that the user has to enter and the things that must be stored.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG.

For example, a user may say, "The TEX just completed.
T. I want to send a document called DOC to Mr. Yamada by e-mail. " At this time, the user gives an instruction from the input means 10 with a message such as “document, Yamada, mail” or “mail, Yamada”, which is a combination of simple keywords. Here, if the user's input is "mail, Yamada", "from input means" mail, Yamada "" is transmitted from the input means 10 to the message management / interpretation means 1 (1001).

The message management / interpretation means 1 uses the registered word dictionary 2 to interpret the meaning of the keyword in the message (102, 201). For example, the registered word dictionary 2 is as shown in FIG. 2, and it is known that the keyword “mail” corresponds to the command of “send mail” or “display mail”, and the keyword “Yamada” is registered in the registered word dictionary 2. Since it has not been determined, it is determined to be the parameter of the above command.

Next, the message management / interpretation means 1 issues a search instruction regarding the keyword "Yamada" to the history search means 7 (107). The history search unit 7 searches the history database 8 (708, 807) and searches the history for checking how the keyword “Yamada” was used in the past.

For example, when the history database 8 stores the history of exchanges between the input means 10, the output means 11 and the command execution means 9 as shown in FIG. 3, the keyword "Yamada" is "(telephone number It can be seen that it has been used as “personal name (which is a search key)”, “destination (such as FAX or email)”, and “source (such as FAX or email)”. Message management of this result /
It returns to the interpretation means 1 (701).

The message management / interpretation means 1 knows that the keyword "Yamada" may be used as "personal name", "destination" or "source" by searching the history of the history search means 7 ( 701), the message format knowledge 3 describing the correspondence between the command and the parameter of the command is searched (103, 301), and if the meaning of the keyword "mail" is mail transmission, the keyword "Yamada"
Knows that is used as the value of the destination parameter, and is used as the value of the source parameter in the case of mail display. Here, FIG. 4 shows an example of the message format knowledge 3. Finally, in the message management / interpretation means 1, the input from the user is “mail transmission, destination is Yamada”
It is determined to mean either "mail display, sender is Yamada".

Here, another embodiment of the message format knowledge 3 will be described with reference to FIG. For example, when the input from the user is "tomorrow, mail, Yamada", the message format knowledge 3 is as shown in FIG. In the same manner as described above, the message management / interpretation means 1 searches the registered word dictionary 2 (102), and the keyword "mail" corresponds to the command "send mail" or "display mail". , 201 know that the keyword "tomorrow" represents tomorrow's date (201). Next, the message management / interpretation means 1 issues a search instruction to the history search means 7 regarding the keyword "Yamada" (107), and the keyword "Yamada" may be used as "personal name""destination""sender". Know that there is (701). The message management / interpretation means 1 searches the message format knowledge 3 (103, 301), and the keyword "tomorrow" is out of the range of the parameter "reception date and time", so that the meaning of the keyword "mail" is not a mail display. , It is determined that the mail is sent.

The input from the user is "mail, Yamada", and the message management / interpretation means 1 is "mail transmission, destination is Yamada" or "mail display, source is Yamada".
If it is determined that the meaning means any of the above, the situation judgment means 4 is requested to judge which meaning is appropriate (104).

The situation judging means 4 issues a history retrieval instruction for applying the rule described in the situation knowledge 5 to the history retrieval means 7 (407) and retrieves the history database 8 (708, 807). Is received (704), the situation knowledge 5 is used (405, 504), and the question from the message management / interpretation means 1 is answered (401). The details will be shown below.

First, FIG. 6 shows an example of the situation knowledge 5. In this example, "Rule 1: If the user gives an instruction to send a mail, a mail sending request message is sent to the command executing means 9""Rule 1 ': Rule 1 is satisfied and no send file is specified, If the user created the document before that,
"Send the created document""Rule 2: If the user instructs mail display, send a mail display request message to the command executing means 9""Rule 2 ': Rule 2 is established and the mail to be displayed is displayed. If there is no designation and the user does not read the mail that arrived before that time, the displayed mail will be displayed ”. Here, in the condition section, conditions regarding the contents of the history accumulated in the history database 8 are described. For example, rule 1 specifies that the condition is a history from the input means and the content is a mail transmission command. It also indicates that a variable is indicated by a number prefixed with% and that the value of the parameter is substituted for the corresponding variable. This variable value is used when assembling a message in the execution unit. The execution unit has a description that defines the transmission destination of the message, which is information output to the command execution unit or the output unit, and the content thereof. For example, Rule 1 describes that the command execution means is notified of a command for mail transmission. It is also specified that the parameter of this command uses the variable value substituted in the condition part. That is, in the example of rule 1, the parameter of the command of the output message, "destination", is the history that matches the condition part in the history, and the value of the "destination" that is the parameter used in the command. Will be used as is.

The user originally thought that "I want to send the created document to Mr. Yamada by mail." Therefore, in the history database 8, a message indicating that the user wants to create a document and TEXT. A message from the command executing means 9 meaning that a document called DOC has been created is recorded as a history as shown in FIG.

The situation judging means 4 assumes one of a plurality of interpretations of the input from the user, and the history searching means 7
(407, 704), the history database 8 is searched (708, 807), and it is checked whether there is a rule that holds in the situation knowledge 5 (405, 504).

When a plurality of rules are satisfied, the rule matching the more recently recorded message is given priority. It is highly likely that the interpretation that corresponds to the established rule is the most appropriate interpretation. In this case, the history of document creation is recent, and it is determined that the rules 1 and 1'of the situation knowledge 5 are suitable for the message recorded more recently. The situation judging means 4 indicates that the user's instruction is “mail transmission, destination is Yamada, transmission file is T
EXT. If there is a high possibility that the interpretation of "DOC" is correct, it returns to the message management / interpretation means 1 (401).

Message management / interpretation means 1 is output means 1
The user is confirmed through 1 (1011). After confirming with the user, the history recording means 6 is instructed (106), and the history database 8 is displayed with “from input means“ mail transmission,
Destination = Yamada, Transmission file = TEXT. "DOC""is written (608). When the status judgment means 4 is informed by the message management / interpretation means 1 that the history database 8 has been rewritten (104), a rule that holds is searched from the situation knowledge 5 (405, 504), and rule 1 holds. Therefore, the status determination means 4 follows the rule 1 and sends the message management / interpretation means 1 to the "to command execution means" mail transmission, destination = Yamada, transmission file = TEX.
T. DOC ”” is requested to be transmitted (401). When the message management / interpretation means 1 sends a message to the command execution means 9 (109), the command execution means 9 executes the command and the purpose of the user is achieved.

Another embodiment of the situation knowledge 5 is shown in FIG. For example, when the command executing means 9 receives an e-mail sent from Mr. Yamada to the user, “from
Command execution means "Mail reception, sender = Yamada,
Message management / interpretation means 1
(901). Since the message from the command execution means 9 is transmitted to the message management / interpretation means 1 in the format defined by the message format knowledge, the message management / interpretation means 1 records the message from the command execution means 9 in the history recording means 6. (106), and the history recording means 6 records in the history database 8 (608). The message management / interpretation means 1 instructs the history recording means 6 to record and at the same time informs the situation determination means 4 that the history database 8 has been updated (1
04).

The situation judging means 4 instructs the history searching means 7 to search the history written in the history database 8 (407). The history search means 7 searches the history database (708, 807) and the situation determination means 4 displays “fr”.
om command execution means "mail reception, sender = Yamada,
"" Is returned (704). Situation judging means 4
Checks for a rule that satisfies the condition in the situation knowledge 5 (405, 504).

If the rule is described in the situation knowledge 5 as shown in FIG. 8, the situation judging means 4 sends the message “to output means“ mail arrival, sender = Yamada ”” to the message management / interpretation means 1. Message (301), the message management / interpretation means 1 commands the history recording means 6 (10
6) It is recorded in the history database 8 (608), and the message from the situation judging means 4 is transmitted to the output means 11 (1011).

In the output means 11, by converting the value of the parameter included in the message into the template, it is converted into a sentence understandable to the user, such as "I received an e-mail from Mr. Yamada", and the user is informed. Present.

Further, for example, after the mail arrives from Mr. Yamada to the user, the user thinks "I want to display the mail sent from Mr. Yamada", and the input means 1 is used as in the above example.
Consider the case where "mail, Yamada" is entered from 0. In the history database 8, “to output means“ mail arrival,
Since the history "Sender = Yamada""is left, rules 2 and 2'are established by the procedure similar to the above example, and the purpose of the user who wants to display the mail is achieved. In this way, even if the input from the user is exactly the same, the input from the user can be judged according to the situation up to that point to achieve the purpose of the user.

Next, a second embodiment of the present invention will be described with reference to FIG.

The flow from processing the input from the user to writing it in the history database 8 is the same as in the first embodiment of the present invention described above.
Is the same as the embodiment described above.

Since the parameter dictionary 13 is used for searching, it is created by the history data stored in the history database 8 in the following procedure.

When a history is added to the history database 8, the history inference means 12 retrieves the history added to the history database 8 through the history search means 7 (120).
7, 708, 807, 7012), the parameter dictionary 13
Is updated (12013, 13012).

FIG. 10 shows an embodiment of the parameter dictionary 13. The parameter dictionary 13 is a keyword-group N
It is composed of a correspondence table including a correspondence table and a group No-attribute name correspondence table.

For example, consider the case where a history is added to the history database 8 as shown in FIG.

When a history meaning that "the keyword Tanaka has been used as a value of a person's name for searching a telephone number" is written, the group number of the parameter dictionary 13-the group number of the attribute name correspondence table ""Personname" as an attribute name in the "1" column, "Tanaka" in the keyword column of the keyword-group No correspondence table, and "1" in the group number column corresponding to "Tanaka" in the keyword-group No correspondence table Is written (12013).

Next, when a history meaning that the keyword "Tanaka has been used as a value of a destination for mail transmission" is written, the keyword-group No.
Since “Tanaka” has already been entered in the keyword column of the correspondence table, and “1” has been entered in the group number column corresponding to “Tanaka” in the keyword-group No correspondence table, the parameter dictionary 13 An attribute name "destination" is added to the group number "1" column of the group number-attribute name correspondence table (12013).

Next, when a history meaning that "the keyword" Tanaka has been used as a sender value for displaying mail "" is written, the keyword-group number is written.
Since "Tanaka" has already been entered in the keyword column of the correspondence table, and "1" has been entered in the group number column corresponding to "Tanaka" of the keyword-group No correspondence table,
The attribute name "sender" is added to the group number "1" column of the group number-attribute name correspondence table of the parameter dictionary 13 (12013).

Next, if a history is written that means that the keyword "Yamada was used as the value of a person's name for searching a telephone number" is written, "Keyword-Group No. Correspondence Table" indicates "Keyword". “Yamada” is entered, and “person name” is entered in the group number “1” column of the group number-attribute name correspondence table of the parameter dictionary 13, so the group corresponding to “Yamada” in the keyword-group No correspondence table. “1” is written in the No field (12013).

As described above, the history inference means 12 collects the attribute names that have the same keyword as a value into the same group, and determines in which group a certain keyword has been used as the value of the attribute. Register in the parameter dictionary 13.

Consider a case where the search request for the keyword "Yamada" is received when the contents of the parameter dictionary 13 are configured as described above.

Upon receiving the search request from the message management / interpretation means 1, the history search means 7 issues a search instruction to the history inference means 12 (7012).

The history inference means 12 searches the parameter dictionary 13 (12013, 13012) and finds that the keyword "Yamada" may be used as "personal name", "destination" and "source". It returns to the history search means 7 (1207), and the history search means 7 returns the result to the message management / interpretation means 1 (701).

By the above processing, even if the history that the keyword “Yamada” described in FIG. 11 is used as the value of “destination” or “source” is not recorded in the history database 8. , By using other histories, it is possible to indirectly know that the keyword “Yamada” may be used as the value of “destination” or “source”, and it is possible to supplement the information. .

Next, a third embodiment of the present invention will be described with reference to FIG.

In the third embodiment, since the history of the work performed by the user is recorded in more detail, the external information acquisition means 14
The information obtained in step 1 is added to the information from the message management / interpretation means 1 and stored in the history database 8.

The external information acquisition means 14 has a plurality of known sensor channels such as a position sensor, and particularly collects information (first information) other than the information input by the user from the outside.

Here, as an example, the user inputs means 10
Consider a case where a document file storage request is made through. This request is finally processed by the command executing means 9 through the processing described in the second embodiment of the present invention, and a history saving request that the document file is stored is issued by the message managing / interpreting means 1 as an event. Data generation means 15
(1015). In response to this request, the event data generation means 15 requests the external information acquisition means 14 to acquire external information (15014).

At this time, the event data generating means 15
A list of external information to be collected regarding the “file storage request” is obtained from the event dictionary 16 (15016, 16
015), and at the same time, send it to the external information input means 14. As shown in FIG. 13, the event dictionary 16 describes the contents of the input from the user (contents of the message from the message management / interpretation means 1) and a list of external information to be acquired in relation to the contents. List of external information (second information)
Is an attribute name of information to be acquired, such as "work place", and external information acquisition means 14 for acquiring the information.
The name of the information source (sensor channel) is described in. The external information acquisition means 14 acquires the information of the requested list from each sensor channel and sends it to the event data generation means 15 (14015). For example, if an entrance / exit management system using an ID card is used, the number of people entering and leaving the room is managed along with the time information. Therefore, the place (Where) and the participants of the meeting (Who) and time (When) can be obtained as external information from the entry / exit history information of the conference room.

In the event data generation means 15, the history information from the message management / interpretation means 1 and the information from the external information acquisition means 14 are grouped into 5W1H (so-called when, where, who, who and what. , How, etc.) is registered in the history database 8 as event data having a basic format (1508).
FIG. 14 shows an example of registered history information. When this history is registered, it is assumed that the message management / interpretation unit 1 makes a search request using the keywords “yesterday”, “meeting”, and “material”. This is an input, for example, when searching for “materials used in the meeting yesterday”. The search expression conversion means 18 receives these keywords.
Uses the search expression dictionary 19 to convert into a history search expression format such as a history search expression or an event-related expression (18019, 19018).

The search expression dictionary 19 describes information for converting an input from a user into a history search expression or an event-related expression.

FIG. 15 shows an embodiment of the search expression dictionary.
The history search expression is an expression for searching a history, and the event-related expression is an expression mainly representing a time order relation of events. In this example, what is preceded by the symbol $ represents a variable. In particular, $ current_date is
This is a system variable indicating the current date.

When the input is "yesterday", "in a meeting", and "material", if the search date is August 5, "yesterday" →
“Date (“ 94/8/4 ”)”, “Meeting” → “d”
uring (“meeting”) ”,“ Where = “meeting room” ”,“ material ”→“ What = “data storage” ”. Where date, duration
Is an event-related expression that defines the time range of each event in the history. If the converted expression includes an event-related expression, the data is sent to the event-related extraction means 17 (18017).

In the event relation extraction means 17, the duri
An event related expression defined by ng or date is converted into a history search expression by searching the history database 8. For example, "during (" meeting ")" refers to the time between events called "meeting" and by extracting the start and end times of a meeting event from historical data,
Get a concrete time representation. In the case of the history shown in FIG. 14,
“When ≧“ 94/8/4 10:00 ”and
The search expression “When ≦“ 94/8/4 11:00 ”” is one candidate that satisfies “during (“ meeting ”)”. Further, from the expression “date (“ 94/8/4 ”)”, “When ≧“ 94/8/4 0: 0 ”
0 ”and When <“ 94/8/5 0: 0
Get the expression "0"". The converted search expression is returned to the search expression conversion means 18 (17018).

In the search expression conversion means 18, the history satisfying the search expression conditions for all user inputs is
Obtained by searching the history database 8 (1808,
8018). In the case of input examples such as “yesterday”, “in a meeting”, and “material” in the present embodiment, “data storage (“ file ”
The history "X") "is to be searched. Finally, from the history of the search target, "file" corresponding to "material"
You can get the file name "X".

As described above, by recording the work status of the user in more detail and using the information, the accuracy of the interpretation of the user's intention can be obtained even with a simple input from the user. It becomes possible to raise.

Next, a fourth embodiment of the present invention will be described with reference to FIG.

In the fourth embodiment, processing for generating a search expression dictionary is added to the third embodiment of the present invention, and the other processing is the same as in the third embodiment.

The search expression dictionary generating means 20 reads the event data recorded in the history database 8 and the pattern defined in the event item relation definition table 21 (8020, 21020) and is defined in the event item relation definition table 21. The frequency of event data that matches the specified pattern is counted. The count result is written in the event item relation table 22 together with the corresponding event data (20022).

FIG. 17 shows an example of the event item relation definition table 21. Here, “*” is a regular expression that matches a character string of 0 or more characters. In this example, if the expression "meeting" appears in the history, it means that the relation with the information of the Where item should be extracted. If there is such a definition and the history shown in FIG. 14 is recorded in the history database 8, the data shown in FIG. 18 is recorded in the event item relation table 22.

The search expression dictionary generating means 20 reads the event item relation table 22 (22020) and, if the recorded count is larger than a predetermined specified value, converts the data corresponding to the search expression dictionary 19. Then
It is registered in the search expression dictionary 19 (20019). For example,
From the data shown in FIG. 18, “* meeting *” → “Where
Data for converting the search expression dictionary “e =“ 3502 conference room ”” is generated, and in the example of the search expression dictionary 19 illustrated in FIG. 15, the data is used to input “meeting” in the item input by the user. In the item of the history search expression "Where =
By adding "3502 conference room", it is possible to generate the search expression dictionary 19.

The embodiment of the present invention has been described above.
The present invention is not limited to these examples, and can interpret various input forms. For example, the user's input is not limited to input from the keyboard, and voice input, menu selection input using a mouse or a pen, handwritten character input using a pen, and the like can be used.

In the embodiment described above, the registered word dictionary 2
The input from the user was interpreted in the order of interpreting the meaning of the command using, the interpreting the parameter using the parameter dictionary 13, and interpreting the message format using the message format knowledge 3. Format interpretation and parameter interpretation may be performed in this order.

[0069]

By configuring the apparatus as described above, when the instruction from the user includes ambiguity in which there is no restriction on the arrangement of a plurality of keywords, or when the instruction includes information In the case of omissions, it is possible to determine which interpretation is most likely when different interpretations have to be done depending on the user's situation.
