Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a context understanding support device for understanding the outline of an input document in an electronic document processing device.

Conventional technology When a function is required to extract only the most important points from an input document displayed on a display screen, the syntactic structure contained in the text is used to extract the main points, allowing the user to Devices already exist that attempt to aid in understanding content.

Problems to be Solved by the Invention However, since conventional context understanding support devices focus on specific syntactic structures, important matters may be overlooked.

In view of the circumstances of the entrustment, the present invention aims to track the transition of matters related to specific matters specified by the user without relying on specific syntactic structures and without overlooking important matters. The purpose is to provide a context understanding support device that is capable of

Means for Solving the Problems The present invention has a human power unit that inputs a document, a syntactic analysis unit that analyzes the syntactic structure of an input sentence input from an input unit, and a semantic analysis unit that analyzes the meaning of the input sentence. A noun phrase specification section that specifies a specific noun phrase in the input sentence, a dictionary section that stores information such as parts of speech and synonyms of words, and all words that are synonymous with the noun phrase specified in the noun phrase specification section. a noun phrase search unit that searches for a predicate in a document according to the noun phrase searched by the noun phrase search unit; and an input sentence and analysis results by the syntactic analysis unit and the semantic analysis unit. and a storage unit that stores the search results of the noun phrase search unit and the predicate search unit;
The display unit is configured to include a display unit that displays the predicates searched by the predicate search unit.

Operation In the present invention, in the above configuration, when a sentence is input, the syntax analysis unit analyzes the syntax of the input sentence with reference to the dictionary unit. Next, when the user specifies a specific noun phrase included in the input sentence, the search unit searches for the specified noun phrase and a noun phrase that is synonymous with the specified noun phrase by referring to the dictionary. Finally, based on the results of the syntactic analysis already obtained, the specified noun phrases are searched for and displayed in sentences containing these noun phrases as nominative or objective cases. You can follow the transition of the things expressed by the noun phrases in context.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of the context understanding support device.

In FIG. 1, l is an input section, 2 is a syntactic analysis section, 3 is a semantic analysis section, 4 is a noun phrase specification section, 5 is a noun phrase search section, 6 is a predicate search section, 8 is a dictionary section, and 9 is a 10 is a storage section and a display section.

Next, the operation will be explained with reference to FIG.

The document input from the input section l is stored in the storage section 9 and is also sent to the noun phrase specifying section 4 and the syntactic analysis section 2. The syntactic analysis unit 2 performs syntactic analysis by referring to syntactic information such as part of speech and conjugation in the dictionary unit 8. This parser 2
When the analysis process is completed, the results are stored in the storage section 9 and sent to the semantic analysis section 3. The semantic analysis section 3 performs semantic interpretation, such as the meaning of each word as a component of a sentence, based on the semantic information from the dictionary section 8, and stores the results in the storage section 9. Ru.

On the other hand, the user specifies a noun phrase on the input sentence sent to the noun phrase specifying section 4. The designation result is sent to the noun phrase search unit 5, which refers to the part-of-speech information and semantic information in the dictionary unit 8 to determine whether this noun phrase appearing in the input document or the noun in the designated noun phrase is an antecedent. All noun phrases containing the pronoun, nouns synonymous with this noun, etc. are searched. The search results are stored in the storage unit 9, and at the same time, the predicate search unit 6
sent to. The predicate search unit 6 uses the syntactic analysis results of the syntactic analysis unit 2 and the semantic analysis results of the semantic analysis unit 3, which are stored in the storage unit 9, to determine the noun phrase that is the search result of the noun phrase search unit 5. Predicates that have as the nominative or objective case are searched. The search results of the predicate search unit 6 are sent to the highlighting processing unit 7 and stored in the storage unit 9.

The highlighting processing unit 7 uses the results sent from the predicate search unit 6 as a second
The highlighted display is processed as shown in the figure. The result of the highlighting process by the highlighting processing unit 7 is displayed to the user on the screen of the display unit IO.

FIG. 2 fa is an example of an input document input from the input unit 1.
), if the user specifies ``fat'' as a noun phrase for this input sentence sent from the input section l to the noun phrase specifying section 4, then the pronoun "He" is searched by the noun phrase search unit 5, and the predicate search unit further searches for "he" and "was playing" as predicates for them.
The following three words were searched: ``started running'' and ``caught out laughing.''

Therefore, the result of the highlighting process performed by the highlighting processing section 7 and finally displayed on the display section 10 is as shown in FIG. 2(b).

By reading a document containing the highlighted character string, the user can easily follow the progress of matters related to a specific matter, that is, can get an overview of the input document.

Effects of the Invention As described above, the present invention includes an input section for inputting a document, a syntactic analysis section for analyzing the syntactic structure of an input sentence input from the input section, and a semantic analysis section for analyzing the meaning of the input sentence. A noun phrase specification section that specifies a specific noun phrase in the input sentence, a dictionary section that stores information such as parts of speech and synonyms of words, and all words that are synonymous with the noun phrase specified in the noun phrase specification section. a noun phrase search unit that searches for a predicate in a document according to the noun phrase searched by the noun phrase search unit; and an input sentence and analysis results by the syntactic analysis unit and the semantic analysis unit. , a storage section that stores the search results of the noun phrase search section and the predicate search section, and a display section that displays the predicates searched by the predicate search section.

This construction allows you to
Moreover, it becomes possible to follow the changes in matters related to specific matters designated by the user without overlooking important matters.
