Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a device for presenting documents.

[0002]

2. Description of the Related Art Conventional techniques include ordinary retrieval systems, version management techniques, memory reproduction techniques, and document retrieval techniques by events.

A typical search system provides a search key,
Present the hit to the user. For example, UNI
In the X (registered trademark) grep, a plurality of files can be designated and a file matching the search key can be searched (reference [1]). In addition, recently, even if the search key does not exactly match the search key, information that has a similar key will be searched.
So-called "fuzzy search" has become possible.

Next, the version management technique will be described. UNIX tools, such as SCCS and RCS,
There is a version control tool. With this tool, you can save versions of files in sequence and get the version you need when you need it. It is also possible to represent changes in version as a tree structure (reference [2]).

Next, the memory reproduction technique will be described. Reflexible is a typical technology in this field.
CSCW (reference [3]), PEPYS (reference [4])
and so on. The Reflexible CSCW collects and presents the file update date and time of the computer. The user sees the result and recalls the action performed by the user. PEPYS is a technique for combining a badge and other information that automatically informs whereabouts by infrared rays and automatically recording a diary to assist human memory ability.

As a document search technique based on events, there is a document search method described in document [5]. This is to save event data such as update / search of a database, and to search and reproduce a specific state of the database using the event data as a search key. This makes it possible to obtain a document that describes the details of the event.

[0008]

In general document creation, in order to express a certain concept, it is often the case that the final form is gradually made while rewriting many times. Furthermore, the concept itself changes rapidly during the expression. Therefore, an object of the present invention is to collectively search and present a series of documents written based on a concept that gradually changes. By listing this series of documents, you can see how the concepts have changed.

It is possible to perform a search with a certain degree of ambiguity even in a normal search system. However, when the concept itself changes, even if the change is small at one time, the final sentence often changes completely from the initial one. In such a case, it is difficult for a normal search system to grasp the transition of the concept.

In the version management system, it is possible to represent the transition of the document itself by using the version tree. However, there is a problem that it can be managed only in a large unit called a document. Also, every time the user creates a document, the operation of forming the version tree and the reason thereof must be described, which makes the operation complicated.

Among the memory reproduction techniques, Reflexible
Although e-CSCW produces a record of file changes, it is almost impossible to see the transition of a particular concept while looking at it. Although PEPYS automatically creates a diary, it is based on data such as human movements, and cannot grasp the transition of concepts included in a document.

The document retrieval technique based on an event is for obtaining the document information in which the details of the event are recorded by reproducing the state of the database at that time based on the history information of the event. However, it is impossible to remember all the events related to a certain concept, and even if a document can be retrieved, it is difficult to grasp the transition of the concept based on it.

It is an object of the present invention to enable the content of a document that changes gradually to be tracked over time.

The specified search condition is stored in the search condition holding means 2. The document search means 3 searches the past document stored in the document storage means 4 according to the conditions stored in the search condition storage means 2, and in some cases including ambiguity,
It is stored in the search result holding means 7. Search condition replacement means 6
Replaces the search condition stored in the search condition storage unit 2 with the search result stored in the search result storage unit 7. In this way, the search is repeated until there are no documents to be searched. Since the document search means 3 performs a search including ambiguity, as the search is repeated, the search condition gradually changes according to the transition of the search result. In this way, the search result holding unit 7 stores the document information searched based on the gradually changing search condition. Then, the information stored in the search result holding means 7 is presented to the document presenting means 9. Document presentation integration means 1
Reference numeral 1 is a unit for integrating information of the same document included in the search results according to a plurality of search conditions. The document presentation changing unit 10 displays the transition of the document presented to the document presenting unit 9 by distinguishing whether the transition of the document is retrieved by exact matching with the condition or is retrieved in a form including ambiguity. Is.

The document operating means 5 is a part for performing all operations related to a document such as editing, displaying, transferring, and printing. The operation performed here is stored in the document operation holding means 12 by the document operation recording means 8.

The transition of the document can be presented based on the operation information.

[Overall Configuration-In Case of Reading] FIG. 2
FIG. 1 is a block diagram showing an overall configuration of a document search / presentation device which is an embodiment for carrying out the present invention by sequentially reading documents and determining the same. The document holding unit 4 is a unit for storing a document created in the past. The user gives an instruction from the condition instructing means 1 to the discrimination condition for presentation. In the present embodiment, it is assumed that the text in the document currently being created is designated. The specified determination condition is stored in the presentation condition holding unit 13. The document reading unit 15 is a unit that sequentially reads the document information stored in the document holding unit 4. The presentation discriminating unit 14 discriminates the past document read by the document reading unit 15 according to the condition stored in the presentation condition holding unit 13 and in some cases including ambiguity, and the document information determined to be presented. Is stored in the discrimination result holding means 17. The presentation condition replacement unit 16 replaces the determination condition stored in the presentation condition holding unit 13 by using the determination result stored in the determination result storage unit 17.
This way, until there are no more documents to read,
Repeat discrimination. Since the presentation discriminating unit 14 makes a discrimination including ambiguity, as the discrimination is repeated, the discrimination condition gradually changes in accordance with the transition of the discrimination result.
In this way, the determination result holding unit 17 stores the document information read based on the gradually changing determination condition. Then, the information stored in the determination result holding unit 17 is presented to the document presenting unit 9. The document presentation integration unit 11 is a unit for integrating the information of the same document included in the results searched according to a plurality of search conditions. Whether the transition of the document presented to the document presentation unit 9 has been searched by the document presentation change unit 10 by perfect matching with the condition,
This is a means for distinguishing and displaying whether or not the search was made in a form including ambiguity.

The document operating means 5 is a part for performing all operations related to the document such as editing, displaying, transferring, and printing. The operation performed here is stored in the document operation holding means 12 by the document operation recording means 8. The information of the document operation holding means 12 is displayed on the document presenting means 9,
The transition of the document can be presented based on the operation information.

[Document Operation and Recording] FIG. 4 is a flowchart showing a process of operating a document and recording the operation. The user first specifies the document to be operated (step S4a). Next, view, edit, manage,
The document information stored in the document holding unit 4 in the form shown in FIG. 3 is operated by the document operating unit 5 that performs operations such as printing and transferring (step S4b).

The process of document operation in step S4b is shown in detail in FIG. First, a user's document operation instruction designated by a command or the like is accepted (step S5a). Then, appropriate processing is activated according to the type (step S5b). For example, when a document transfer instruction is received, the user inputs the transfer destination. Then, based on this, preparation for transfer such as adding a header is performed (step S5c). Then, the document operating means 5 actually transfers the document information through the mail system or the like (step S5d). Next, the operation type (transfer), operation date and time, operation target document ID, detailed information (transmission target, transmission success / failure ...) Of this operation are created as transfer operation information (step S5e). . When printing is instructed, a print image is created by converting the document format of the apparatus into a print control language interpreted by the printer (step S5f). The document operation unit 5 actually prints it on the printer (step S5g). Next, the operation type (print) of this operation,
Operation date / time, operation target document ID, detailed information (printer name, print success / failure, paper size, number of prints ...
.) Is created as print operation information (step S5h). When the document management command is received, the name is changed or the directory is moved (step S5).
i). Next, the operation type (management) of this operation, the operation date and time,
The document ID of the operation target, detailed information (operation contents such as name change and move, name before change, position before move ...) Are created as management operation information (step S5).
j). When the display is simply instructed, a display image such as a bitmap is created so that it can be displayed on the screen (step S5k). Then, the image is displayed on a display or the like (step S51). Next, the operation type (display), operation date / time, operation target document ID, detailed information (display name, display position, size /
..) is created as the display operation information (step S5m). When the editing process is instructed, a display image such as a bitmap is created so that it can be displayed on the screen (step S5n). Then, the image is displayed on a display or the like (step S5o). And
An edit command such as addition / deletion is accepted from the user (step S5p). The content of the document is actually changed based on the command (step S5q). This process is repeated until the editing is completed (step S5r). Next, the operation type (edit) of this operation, the operation date and time, the document ID of the operation target, and the detailed information (the number of edited bytes, the display position,
Size ...) Is created as display operation information (step S5s).

As shown in FIG. 5, the document operation recording means 8 monitors the operation performed by the document operation means 5 and stores it in the document operation holding means 12 in the form of FIG.
Here, the table is managed in the table of operation ID, operation date and time, ID of the document to be operated, operation type, and operation details. The operation ID is a numerical value assigned so that the recorded operation can be uniquely identified. Operation date and time, Document I
D and operation type are the operation date and time, the document ID of the operation target, and the operation type included in the operation information generated in step S5e, step S5h, step S5j, step S5m, and step S5s. The detailed information is generated in the same way. For transfer, the transmission target and transmission success / failure, for printing the printer name and print success / failure, paper size and number of prints, and for management operations, management Information such as the type, name before change, position before movement, display name and display position / size in the case of display, edit amount in the case of editing, display position and size, and the like are stored (step S4c).
Then, the document operation and the operation recording process are repeated in response to the user's request (step S4d). From the above,
It is possible to perform an operation on a document and save a record of the operation history.

[Preparation for Presenting Concept Transition by Search ... Basic Form] As a preparation for presenting the concept transition included in the created document, the document information stored in the document holding means 4 is searched for the relation. The process of picking up document information will be described. FIG. 7 is a flowchart showing this processing. In addition, a series of documents expressing a concept to be transitioned will be referred to as concept transition data hereinafter.

First, search conditions are set. here,
“This visualization technology also tends to be used for the purpose of visualizing scientific data. Is used as a search key. The conditions input from the condition designating means 1 are stored in the search condition holding means 2 in the form of "initial state" in FIG. 8 (step S7a). The document search unit 3 searches the document data stored in the document storage unit 4 using the exact match search condition among the conditions stored in the search condition storage unit 2 (step S7b). If there is a document that matches the search condition (step S7c). The result is saved in the search result holding means 7 in the form of FIG. here,
Search conditions for searching the document, positions in the document that match the conditions (number of characters from the start position of the document), document creation date and time (document creation date and time in FIG. 3), document ID (document ID in FIG. 3), etc. The table describing is stored (step S7d). Then, the search target is limited to data older than the searched document data. The period is limited in the "period limited" portion of the table of FIG. 8 (step S7e). Next, the search conditions are relaxed.
The search conditions are relaxed in the "condition relaxation" part of the table of FIG. Here, if most of the main words in the document are included, they are searched. In this example, the search condition is relaxed on the basis that the main word is included. However, if the thesaurus is used, it is possible to judge the word in which the main word is expanded by measuring the goodness of fit. The thesaurus can be held, for example, in the document holding unit 4, or can be developed by using a commonly provided thesaurus outside. According to this usage, the search condition after the condition relaxation in FIG. 8 is “science (science, natural science, social science, human science, Science)”, “data (information, Data, knowledge)”, “visible (visible , Visual) ”,
80% of "uses (use, purpose, aim, aim, goal, use)", "visual (visible, visible)", "use (use, exercise, operation, use, application, pass)" are included. become. In addition, without using a thesaurus, it is easier to read "", "", "", "", "", "" and "".
80% or more of the characters are included. ” As described above, if the search condition is ambiguous, it may be converted into any condition (step S7f). Then, using this condition, the period limited by step S7e is searched (step S7g). If there is a document that meets the conditions (step S7h), the result is recorded in the form of FIG. 9 as in step S7d (step S7i). Then, the search target period is limited to data older than the searched document data (step S7j). Then, the part suitable for the search included in the searched document is extracted, and the extracted part is registered as a new condition. In the example of FIG. 8, the "condition replacement" portion expresses the state of the search condition after the conditions have been replaced by extraction (step S7k). The above process is repeated until there are no more search targets (step S71).

[Preparation for Presentation of Concept Transition by Reading ... Basic Form] As a preparation for presenting the transition of the concept included in the created document, the document information stored in the document holding unit 4 is sequentially read to create a document. The process of picking up the transition of the concepts involved will be described. FIG. 10 is a flowchart showing this processing.

First, the presentation condition is set. here,
“This visualization technology also tends to be used for the purpose of visualizing scientific data. Is a presentation condition. The condition input by the condition designating means 1 is stored in the presentation condition holding means 13 in the form of "initial state" in FIG. 11 (step S10a). The document reading means 15 sequentially reads the information stored in the document holding means 4 in the form of FIG. 3 one document at a time (step S10b). Presentation discriminating means 14
Determines whether or not the conditions of the presentation condition holding unit 13 are completely met (step S10c). If they match (step S10d), the determination result holding means 17 displays the result in FIG.
It is stored in the form of (step S10e). If they do not match (step S10d), the determination condition is relaxed. The judgment condition is relaxed in the "condition relaxation" part of the table of FIG. 11 (step S10f). Using the relaxed condition, it is determined whether there is a matching portion (step S10g). If there is a matching portion (step S
10h), the currently read document is stored in the discrimination result holding means 17 in the form of FIG. 9 (step S10i). Then, the part suitable for the search included in the recorded document is extracted, and the extracted part is registered as a new condition. In the example of FIG. 11, the “replacement of condition” portion expresses the state of the search condition after the condition is replaced by extraction (step S10j). The above process is repeated until all the target documents are read (step S10k).

[Presentation of Concept Transition Data ... Basic Form] Next, a process of presenting the concept transition obtained by searching or reading will be described. FIG. 12 is a flowchart showing this processing. Further, FIG. 13 is a display obtained as a result of this processing.

First, the time range to be displayed is determined and displayed from the first and last document creation dates and times of the concept transition data stored in the search result holding means 7 or the discrimination result holding means 17 in the form of FIG. The time axis displayed by the straight line in the upper part of FIG. 13 is displayed (step S12a). Then, the conceptual transition data is sequentially selected one by one (one line in the example of FIG. 9) (step S12b). A document icon is arranged on the screen based on the document creation date and time of the selected data. In FIG. 13, icons in the form of documents are arranged in a horizontal row (step S12c). Then, the document name is simultaneously displayed at the position of the icon (step S12d). Further, the document holding means 4 is searched from the document ID to obtain the document length. Next, an image representing an approximate position of a portion that meets the conditions is displayed on the icon based on the retrieval matching position data of the concept transition data and the document length. The gray part on the icon in FIG. 13 represents the condition conforming position (step S12e). If the concept transition data is not the first selection (step S12f), the icons are combined and the type of straight line expressing whether or not the condition relaxation is performed is selected. This is performed by comparing the search condition of the currently selected concept transition data with the search condition of the immediately preceding data (step S12g). Then, the space between the icons is displayed based on the line type determined here. In the example of FIG. 13, when the condition relaxation is not performed, it is represented by a solid line, and when it is performed, it is represented by a dotted line (step S12h). The above processing from S12b to S12h is repeated until all the concept transition data are displayed (step S12i). Through the above processing, the data of the concept transition obtained by the retrieval or reading can be displayed on the document presenting means 9 in an easy-to-understand manner. As a result, it becomes possible to easily understand how the concept indicated by the condition has changed while tracing back the documents created in the past, starting from the given condition.

[Detailed Display by Specifying Document Icon] Next, a process for knowing the contents by directly instructing the document icon obtained by the process of FIG. 12 will be described. FIG. 14 is a flowchart showing this processing.

First, the user designates a document icon on the display of FIG. 13 for which the user wants to know the detailed contents (step S1).
4a). Then, the concept transition data of FIG. 9 is searched from the document icon to obtain the document ID (step S14).
b). The document holding means 4 is searched based on the document ID (step S14c), and the content of the document is presented to the document presenting means 9 (step S14d). In this way, FIG.
As shown in 3, detailed contents of each document icon can be known. In this example, the detailed contents of the document having the document name are displayed.

[Integrated Display Preparation by Multiple Conditions] A process for integrally presenting transitions of a plurality of concepts by displaying a plurality of conditions will be described. FIG. 15 is a flowchart showing this processing.

First, a plurality of presentation conditions are set. Here, "This visualization technology tends to be used for the purpose of visualizing scientific data. Multiple sentences such as “” shall be specified. For example, this corresponds to a case where a paragraph formed of a plurality of sentences is designated (step S15a). Next, one condition is sequentially taken out from the designated conditions to be a target (step S15b). Based on this condition, the presentation process by search shown in FIG. 7 or the presentation preparation by reading shown in FIG. 10 is executed (step S15c). Next, the display position of the result is determined so that the icons do not overlap (step S15).
d), the image representing the concept transition data is presented at the display position as in the process of FIG. 12 (step S15e).
The above processing from S15b to S15f is repeated until all the presentation conditions are completed (step S15f). Furthermore, the document icon presented based on multiple conditions,
If they are the same, they are integrated (step S15).
g).

FIG. 16 is a flowchart showing the processing (step S15g) for this integration. In addition, FIG.
Is a diagram of a result of performing this processing. First, a plurality of conditions are sequentially selected (step S16a). Next, the document icons that are the result of matching the conditions are sequentially selected (step S16b). If there is an icon of the same document among the icons displayed so far (step S16)
c) Delete the currently targeted icon. For example, in FIG. 17, the icon of the document name should originally be displayed as the result of matching the conditions in the second row from the top.
It is deleted because it is also displayed under the condition of the first row (step S16d). Further, if the same position is not presented as the condition conforming position (step S
16e), the matching position information displayed on the document icon that was the processing target is superimposed and presented. Taking the icon of the document name as an example again, since this document icon has two shaded portions, it can be seen that the two positions in this document meet the first and second conditions, respectively (step S16f). Then, along with the deletion of the document icon based on the second condition, the line segment to or from the document icon is moved to the newly unified document icon side (step S16g). The same process is performed when the same position is presented as the condition conforming position (step S16h). The above processing from S16b to S16h is repeated until all the document icons are finished (step S16i). Further, the processing from S16a to S16i is repeated until all the specified conditions are completed (step S16).
j). Through the above processing, the concept transition based on a plurality of conditions can be displayed in an integrated manner.

[Preparation for presentation by reading ... Document operation] The concept transition data is read by sequentially reading the document operation information stored in the document holding unit 4 in preparation for presenting the transition of the concept included in the operated document. The process of picking up will be described. Of course, similar results can be obtained by searching. FIG. 18 is a flowchart showing this processing.

First, the presentation condition is set. here,
“This visualization technology also tends to be used for the purpose of visualizing scientific data. Is a presentation condition. The condition input by the condition designating means 1 is stored in the presentation condition holding means 13 in the form of "initial state" in FIG. 11 (step S18a). The document reading unit 15 sequentially reads the information stored in the document operation holding unit 12 in the form of FIG. 6 one operation at a time (step S18b). Further, the document holding means 4 is searched from the document ID of the operation target to obtain the target document information (step S18c). The presentation determination means 14 determines whether or not the conditions of the presentation condition holding means 13 are completely matched (step S18d). If they match (step S18e), they are stored in the discrimination result holding means 17 in the form of FIG. In this example, the search condition in which the document is searched, the search matching position indicating the position where the search result matches in the document, the target document operation content, and the target document ID (document ID in FIG. 3) Is saved. The document operation content is a combination of the date and time and the operation type from the content stored in the document operation holding unit 12 in the form of FIG. 6 (step S18f). If they do not match (step S18e), the determination condition is relaxed.
The judgment condition is relaxed in the "condition relaxation" part of the table of FIG. 11 (step S18g). Using the relaxed condition, it is again determined whether there is a matching portion (step S18h). If there is a matching portion (step S18i), the operation currently read is stored in the discrimination result holding means 17 in the form of FIG. 19 (step S18).
j). Then, the part suitable for the search included in the recorded document is extracted, and the extracted part is registered as a new condition. In the example of FIG. 11, the "condition replacement" portion expresses the state of the search condition after the conditions have been replaced by extraction (step S18k). The above process is repeated until all the desired operations are read (step S181).

[Presentation of Concept Transition Data Based on Document Operation] Next, a process of presenting the concept transition obtained by searching or reading based on the operation will be described. 20
It is a flowchart showing this process. Also, FIG.
Reference numeral 1 is a display obtained as a result of this processing.

First, the retrieval result holding means 7 in the form of FIG.
Alternatively, the time range to be displayed is determined and displayed from the first and last document creation dates and times of the concept transition data stored in the discrimination result holding means 17. The straight line in the upper part of FIG. 21 represents the time axis (step S20a). And
Concept transition data are sequentially transferred one by one (1 in the example of FIG. 19).
Line by line) to select (step S20b). A document icon is arranged on the screen based on the document creation date and time of the selected data. In FIG. 21, icons in the shape of a document are arranged in a horizontal row (step S20c). The document name is simultaneously displayed at the position of the icon (step S20d).
Then, according to the operation expression image shown in FIG. 22, an image expressing the type of operation is displayed so as to be superimposed on the document icon (step S20e). Further, the document holding means 4 is searched from the document ID to obtain the document length. Then, an image representing the approximate position of the part that meets the conditions from the search matching position data of the concept transition data and the document length is displayed over the icon. The shaded portion on the icon in FIG. 21 represents the condition conforming position (step S20f). If the concept transition data is not the first selection (step S20g), the icons are combined and the type of straight line expressing whether or not the condition is relaxed is selected.
This is performed by comparing the search condition of the currently selected concept transition data with the search condition of the immediately preceding data (step S20h). Then, the space between the icons is displayed based on the line type determined here. In the example of FIG. 21, when the condition relaxation is not performed, it is represented by a solid line, and when it is performed, it is represented by a dotted line (step S20).
i). The above processing from S20b to S20i is repeated until all the concept transition data are displayed (step S
20j). By the above processing, the data of the concept transition obtained by the retrieval or reading can be displayed in an easy-to-understand manner based on the operation on the document. With this, it is possible to easily know how a certain concept is treated and how it has changed.

[0045]

In the present invention, the search result itself is used to
By changing the search key, the contents of the document that gradually change can be tracked over time. This made it possible to revisit the transition of the concept that was formed while gradually changing. This is extremely useful as reference information when clarifying the origin of the concept or when further examining the concept.

Further, the transitions of a plurality of concepts are simultaneously displayed in an easy-to-understand manner. This is effective when it is desired to verify what concept a part of the document currently being created is formed by.

Further, not only the unit of the created document but also all the operations related to the document can be used as a reference to grasp the transition of the concept. By doing so, it is possible to grasp in detail what kind of operation the concept has been subjected to and how it has changed as a result.
