Abstract

According to one embodiment, an input unit accepts input of an input sentence that is a second sentence of the native language corresponding to a first sentence. A language analysis execution unit executes language analysis for the input sentence. A grammatical feature extraction unit extracts a grammatical feature of the input sentence based on a result of the executed language analysis. A search query generation unit generates a search query based on the extracted grammatical feature. An output unit searches for an index based on the generated search query and outputs an exemplary sentence set including an exemplary sentence of the native language corresponding to an index that matches the search query and an exemplary sentence of the foreign language corresponding to the exemplary sentence of the native language.

Claims

a memory configured to store an exemplary sentence corpus that includes an exemplary sentence collection including an exemplary sentence set including an exemplary sentence of the foreign language and an exemplary sentence of a native language corresponding to the exemplary sentence of the foreign language, and an index corresponding to the exemplary sentence of the native language;

an input circuit configured to accept input of an input sentence that is a second sentence of the native language corresponding to the first sentence;

a language analysis execution circuit configured to execute language analysis including morphological analysis and syntax analysis for the input sentence whose input has been accepted;

an output circuit configured to search for the index based on the generated search query and output an exemplary sentence set including an exemplary sentence of the native language corresponding to an index that matches the search query and an exemplary sentence of the foreign language corresponding to the exemplary sentence of the native language.

2. The apparatus of claim 1, wherein the search query generation circuit creates a search query based on the grammatical feature, and extends the created search query, thereby finally generating the search query.

3. The apparatus of claim 2, wherein extending the search query includes applying at least one of indeclinable word abstraction, synonym extension, postpositional particle extension, and intransitive/transitive verb extension to the search query.

4. The apparatus of claim 1, wherein the grammatical feature extraction circuit further comprises:

a semantic attribute analysis circuit which executes semantic attribute analysis of the input sentence based on the result of the executed language analysis; and

an extraction circuit which extracts the grammatical feature of the input sentence based on a result of the executed semantic attribute analysis.

5. The apparatus of claim 4, wherein the result of the semantic attribute analysis includes a semantic attribute of an independent word in the input sentence on a hierarchical level basis,

the extraction circuit extracts the grammatical feature including the semantic attribute on the hierarchical level basis, and

the search query generation circuit generates the search query by selecting the hierarchical level of the semantic attribute to be applied to the search query.

6. A foreign language sentence creation support apparatus for supporting creation of a first sentence of a foreign language, which is a sentence formed from a plurality of clauses including at least an independent word, comprising:

a memory configured to store an exemplary sentence corpus that includes an exemplary sentence collection including an exemplary sentence of the foreign language and an index corresponding to the exemplary sentence of the foreign language;

an input circuit configured to accept input of an input sentence that is a third sentence of the foreign language;

a language analysis execution circuit configured to execute language analysis including morphological analysis for the input sentence whose input has been accepted;

a grammatical feature extraction circuit configured to extract a grammatical feature of the input sentence based on a result of the executed language analysis;

a search query generation circuit configured to generate a search query based on the extracted grammatical feature; and

an output circuit configured to search for the index based on the generated search query and output an exemplary sentence of the foreign language corresponding to an index that matches the search query.

7. The apparatus of claim 6, wherein the memory stores the exemplary sentence corpus including an exemplary sentence collection that further includes an exemplary sentence of a native language corresponding to the exemplary sentence of the foreign language, and

the output circuit further outputs the exemplary sentence of the native language corresponding to the exemplary sentence of the foreign language corresponding to the index that matches the search query.

8. The apparatus of claim 6, wherein the search query generation circuit creates a search query based on the grammatical feature, and extends the created search query, thereby finally generating the search query.

9. The apparatus of claim 8, wherein extending the search query includes applying at least one of indeclinable word abstraction, synonym extension, postpositional particle extension, and intransitive/transitive verb extension to the search query.

10. The apparatus of claim 6, wherein the grammatical feature extraction circuit further comprises:

a semantic attribute analysis circuit which executes semantic attribute analysis of the input sentence based on the result of the executed language analysis; and

an extraction circuit which extracts the grammatical feature of the input sentence based on a result of the executed semantic attribute analysis.

11. The apparatus of claim 10, wherein the result of the semantic attribute analysis includes a semantic attribute of an independent word in the input sentence on a hierarchical level basis,

the extraction circuit extracts the grammatical feature including the semantic attribute on the hierarchical level basis, and

the search query generation circuit generates the search query by selecting the hierarchical level of the semantic attribute to be applied to the search query.

12. A foreign language sentence creation support method in a foreign language sentence creation support apparatus for supporting creation of a first sentence of a foreign language, which is a sentence formed from a plurality of clauses including at least an independent word, comprising:

storing an exemplary sentence corpus that includes an exemplary sentence collection including an exemplary sentence set including an exemplary sentence of the foreign language and an exemplary sentence of a native language corresponding to the exemplary sentence of the foreign language, and an index corresponding to the exemplary sentence of the native language;
