PURPOSE:To provide the automatic generator for retrieval formula by deciding the retrieval arithmetic unit while reading questions written in natural words, deleting unnecessary words, and properly interpreting particles. CONSTITUTION:A morpheme analysis means 2 reads a question 1 to separate words, passing unnecessary words to a deletion means 5. The means 5 deleting unnecessary words gives marks to the parallel particle 'to' (Japanese word having the meaning of 'and') in front of a general term A while referring to a general term dictionary 3 and a thesaurus 4 and passes all the parallel terms, low-order words, and high-order words connected by a case particle 'no' to an operator processing means 6. The operator processing means 6 replaces the marked parallel particles 'to' by AND operators, 'to' having the close meaning of question words before and after by OR operators while referring to a thesaurus 4, all the other particles by OR operators, outputting a retrieval formula 7. |
