Classification: CPC G | IPC G

Claim 6:
7. A non-transitory computer readable storage medium storing a named-entity extraction processing program for causing a computer to function as:
a first storage that stores an extraction dictionary used when named entities of document data and relations between named entities are extracted from the document data;
a document receiving unit that receives input of extraction document data from which the named entities and the relations are extracted, and input of learning document data used for learning of the extraction dictionary;
an extraction unit that extracts, using the extraction dictionary, named entities and relations between named entities from the extraction document data received by the document receiving unit;
a designation unit that designates character strings corresponding to the named entities extracted by the extraction unit among character strings in the learning document data received by the document receiving unit;
a second storage that stores a relation extraction rule in which relations between categories of the named entities extracted from the extraction document data are defined;
a generator that generates, by applying the relation extraction rule stored in the second storage, a learning document in which relations between named entities belonging to the categories defined by the relation extraction rule among the named entities designated by the designation unit are set; and
a learning unit that learns the extraction dictionary based on the learning document generated by the generator.
