TECHNOLOGY FOR RETRIEVING KEYWORD DECIDING OCCURRENCE OF EVENT

摘要

PPROBLEM TO BE SOLVED: To retrieve a keyword, that decides the occurrence of an event, from a text, in which a process to the occurrence of the event is recorded. PSOLUTION: The system includes: a text input part for inputting a plurality of partial texts acquired by dividing each text into a plurality parts by associating them with events occurring after a process recorded in the text; a prediction unit adjusting part for adjusting an event prediction unit to maximize the rate of the texts with which the input event and prediction result are matched among a first text group selected from the plurality of corresponding partial texts with respect to each block; a prediction processing part for generating a prediction result by inputting each of the second text group selected from the plurality of corresponding partial texts to the adjusted event prediction unit with respect to each block; and a retrieval part for comparing the input events and prediction results for every partial text and calculating predicting precision for the second text group of the event prediction unit for every block, and for retrieving a keyword from a block whose predicting precision is higher than the reference value.
