Abstract

PURPOSE:To prepare an index by expanding automatically a heading of an inflective form. CONSTITUTION:A language data generating part 2 generates newly language data of a dictionary. A table consulting part 3 consults an inflective form expansion table 4 by using information (an original form of a heading word, a part of speech, an inflective form) stored in the language data as a consulting subject. The inflective form expansion table 4 expands an inflective form in accordance with an inflective variation in the matched entry. An index preparing part 7 links each expanded inflective form to the language data, and prepares an index.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dictionary creating apparatus, and more particularly to a computerized electronic dictionary creating apparatus.

[0002]

2. Description of the Related Art With the recent development of natural language processing technology,
Computerized dictionaries for computer processing are becoming more important. Since the amount of information written in the dictionary affects the performance of the natural language processing system, the dictionary must be reliable and of high quality without bugs. For that purpose, a dictionary development apparatus has been proposed that allows the user to input language information in a menu system.

By the way, many dictionaries are provided with an index part for searching independently of the data part describing the language information in order to improve the efficiency of dictionary searching. In the conventional dictionary development device, the creation of the data part is simple, but the index part is a method in which a person considers a headword (prototype, inflectional form) for each word and links each to the language data individually.

[0004]

In the above-mentioned conventional method, the creation of the index part is inevitably a very expensive operation. In addition, in languages such as English that have a lot of irregular usage, incorrect usage forms are often linked, and there is a problem that a link mistake due to the carelessness of the creator cannot be prevented.

Further, since the physical link information is the only one that supports the connection between the index and the language data, if a failure occurs in this link information, the index part cannot be restored at all. There are also problems.

[0006]

The present invention provides a dictionary creating apparatus for creating and updating a computerized computerized dictionary having a data section storing language information and an index section for retrieval, and an input from a user. An input section that accepts, a language data creation section that creates new language data based on the information input from this input section, and an inflectional-type expansion table that develops the inflectional forms of the headword from the information stored in the language data. A table drawing section that draws this inflectional expansion table, an index creating section that creates an index of the language data created by the language data creating section, and a dictionary access section that writes the language data and the index to the dictionary. It is characterized by including.

[0007]

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

FIG. 1 is a block diagram of an embodiment of the present invention.

The input unit 1 receives the language information such as the original form of the headword and the part of speech as an input from the user, and transmits it to the language data creation unit 2.

The language data creation unit 2 creates new language data of the dictionary based on the input information. Of the information stored in the language data, the table arranging unit 3 argues the inflectional form expansion table 4 using the original form of the entry word, the part of speech, the inflectional form, etc. as arguments.

The utilization type expansion table 4 is a table composed of entries that describe a search key and utilization changes as shown in FIGS. 2 and 3, and includes an irregular utilization expansion table 5 and a rule utilization expansion table. It consists of 6 tables. In the irregular utilization expansion table 5, words that undergo irregular utilization changes are registered in advance, and the original character string, the part of speech, and the utilization type serve as the search key for the table. On the other hand, in the rule utilization expansion table 6, the character string of the ending of the original form, the part of speech, and the utilization type are used as the search keys.

The table is an irregular utilization expansion table 5,
It is searched in the order of the rule utilization expansion table 6, and the utilization forms are expanded according to the utilization change in the first matching entry,
The result (headword of each inflectional form) is returned to the table siding unit 3.

The index creating unit 7 creates an index by linking each expanded form of utilization to language data. Then, the created language data and index are sent to the dictionary access unit 8.

The dictionary access unit 8 writes the created language data and its index into the data file and index file of the dictionary 9, respectively.

Next, referring to FIG. 4, the operation and data change of the embodiment shown in FIG. 1 will be described.

For example, as an example of Japanese, input 01a,
In the case of newly registering 01b, the language data creating unit 2 uses the data 23a,
Create language data such as 23b. At this point,
The index is linked only to the original form of the entry word that is the input information.

Next, the table pulling unit 3 pulls the inflection type expansion table 4. Since "write" is a rule verb, it matches the following entry in the rule usage expansion table. Prototype ending character string: Ku Part of speech: Verb Inflectional type: Five-stage inflection And the following inflectional forms are developed. Vocabulary 1: Writing Vocabulary 2: Sentences Consecutive Form 1: Writing Sequential Form 2: Writing Ending Form: Writing Conjugation Form: Writing Hypothesis Form: Writing Imperative Form: Writing On the other hand, “go” is an irregular verb "I went" instead of ".", So it matches the following entries in the irregular usage expansion table. Prototype character string: Go Part of speech: Verb Inflectional form: Five-stage utilization The following inflectional forms are developed. Form 1: Form or form Form 2: Form line Consecutive form 1: Go Line Consecutive form 2: Go End form: Go Union form: Go Hypothetical form: Go Imperative form: Go Links are created to create indexes such as data 78a and 78b.

Finally, the language data and index thus created are sent to the dictionary access unit 8, and the dictionary access unit 8 writes them in the dictionary 9.

Regarding the expansive expansion, the language data creating section 2, the table arranging section 3, and the index creating section 7 do not depend on a specific language. It is also possible to automatically expand the usage and create indexes for languages.

As an example of the case of another language, FIG. 5 shows a change in operation and data when inputting English. The flow of processing and changes in data are the same as those in the above Japanese example, and only the results expanded by the inflectional expansion table for English are different.

The matched entries and the expanded results are shown below. "Study" (rule conjugation verb) (entry) pronoun ending character string: consonant + y part of speech: verb conjugation type: unspecified (result) prototype: study third person singular present tense: past past tense: present present participle: studying Past participle form: studied “take” (irregular conjugation verb) (entry) Prototype ending character string: take Part of speech: verb conjugation type: unspecified (result) Prototype: take 3rd person singular present form: takes Past form: talk Present participle: taking past participle: taken

As described above, according to the present invention,
Since it is not necessary for a person to individually create inflectional headings when creating a dictionary, the cost of creating a dictionary can be reduced.
