PROBLEM TO BE SOLVED: To construct precise context information in accordance with a context. SOLUTION: A context processor is constituted of a control part 3 for generating context information, a cooccurrence dictionary 4 for storing cooccurrence data formed of a group of words which tends to appear together and relational information between the words, a coccurrence dictionary retrieval part 5 for retrieving cooccurrence data from the coccurrence dictionary 4 with the word which is read as a retrieval key, a cooccurrence data storage part 6 for storing retrieved cooccurrence data, a context information update processing part 7 for updating context information, a cooccurrence relation decision part 8 for checking whether a group of arbitrary words is stored in the cooccurrence dictionary 4 or not and a context information storage part 9 for storing context information constituted of sets of cooccurrence data. The context information update processing part 7 stores cooccurrence data against individual word in cooccurrence data stored in the cooccurrence data storage part 6, which satisfies a condition that all the words contained in cooccurrence data exist in cooccurernce data stored in the coccurrence data storage part 6, in the context information storage part 9 as context information. |
