Abstract

PURPOSE:To retrieve a word by providing a conjugation absorbing processing section referring to a conjugation absorbing table to obtain an end-form based on a step and an end of word of an end conjugation so as to copy and input a word in a conjugation form as it is from an editer or the like without any modification. CONSTITUTION:When the user gives a retrieval key 'arui(walk)' as input data, an input control section 2 inputs the key 'arui' to a conjugation absorbing processing section 3. Then, the 'arui' is used to reference an irregular conjugation form absorbing table 6 with the retrieval key 'arui' in which a stem and an end of word are set together. When the key 'arui' has not been registered, a rule conjugation table 7 is referred succeedingly. Since indices are registered in terms of end of words in the table 7, the table is referenced based on 'theta' of the word stem 'aruku(walk)' to obtain a corresponding end form 'ku' and 'aruku(walk)' is outputted to the processing section 3. A dictionary retrieval processing section 4 uses the end form 'aruku(walk)' received from the processing section 3 as a retrieval key and refers to a dictionary file 9 for the retrieval and the retrieval result is outputted to an output control section 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dictionary search device in the fields of natural language processing and information search.

[0002]

2. Description of the Related Art In the entry word of a dictionary file, all the words that have been used at the end are converted to the final form.

Therefore, in the conventional dictionary search system,
Unless the inflectional form is converted to the final form, it cannot be used as a search key.

[0004] For example, in the case where an inflectional word in a text is copied as it is and input as a search key from an editor or the like, it is necessary for the user to perform a re-entry operation to correct the inflectional search key to the final form. It was

[0005]

When searching a dictionary, it is possible for a user to copy an inflectional word from a text and search the dictionary by using the word as it is.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a dictionary search device with a Japanese conjugation type absorption mechanism that uses the inflectional form words in a text as a search key.

Therefore, according to the present invention, the verb or adjective described in the text, or an input control unit for inputting a word that is the ending of the adjective as a search key, and a dictionary in which the headword is registered in the final form. A dictionary search processing unit that performs a dictionary search of a file, an output control that outputs a search result of the dictionary file, and a conjugation word input by the user is converted to an terminating word by referring to the conjugation absorption table. And a utilization type absorption processing section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

It is a diagram showing a configuration of an embodiment of the present invention.

In this embodiment, an input control unit 2 for inputting a search key, an inflectional absorption processing unit 3 for converting an inflectional word into an endive word, and a dictionary for retrieving an endive word as a search key. Search processing unit 4 and output control unit 5 for outputting search results
And an inflected absorption table 8 including an irregular inflected absorption table 6 for registering inflected forms of irregularly inflected words and a ruled inflected absorption table 7 for registering inflected forms of irregularly inflected words
And a dictionary file 9 having the final form as a headword.

Further, the irregular utilization type absorption table 6 and the regular utilization type absorption table 7 are illustrated in FIGS. 3 (a) and 3 (b).

Next, the operation of this embodiment will be described with reference to the flow chart 2 and the utilization type absorption table 8. The user
The flow of the processing will be described by taking the case where the dictionary is searched for "walking" in the sentence "he walked".

First, when the user gives the search key "walking" as input data, "walking" is input from the input control section 2 and passed to the inflection type absorption processing section 3 (step 2).
1).

In the utilization type absorption processing section 3, the irregular utilization type absorption table 6 and the regular utilization type absorption table 7 are referred to.
In the irregular utilization form absorption table 6, the utilization expansion forms of irregular utilization words are registered in the form of “stem + ending”. In the rule inflection type absorption table 7, the inflectional inflection endings of the rule inflection words are classified and registered according to the parts of speech, inflection forms, and inflection lines (A line, K line, etc.). The end form corresponding to each utilization expansion form is registered.

When "walking" is passed to the inflectional absorption processing section 3, first, the irregular utilization type absorption table 6 is referred to with the search key "walking" in which "walking" is the same as the stem. (Step 22). If there is the same headword as the search key (Yes in step 23), it is hit and the corresponding end form is output (step 25). If "walking" is not registered (No in step 23), then the rule-based absorption table 7 is referenced (step 24).
Since the headword is registered at the end of the rule inflection type absorption table 7, table reference processing is performed with "φ" whose stem is "empty" to obtain the corresponding final form "ku" and "walk". It is output (step 25) and passed to the inflection type absorption processing unit 13.

The dictionary search processing unit 4 is an inflection type absorption processing unit 3
Using the end form "walking" passed from the search key as a search key, the dictionary file 9 is searched for a search, and the search result is output to the output control unit 5.

[0017]

As described above, according to the present invention,
It has an inflectional absorption processing section that refers to the inflectional absorption table and obtains the inflectional stem and the inflectional end from the inflection. Also, you can search by inputting the inflected word as a search key from an editor.
