UNKNOWN WORD CONCEPT ESTIMATING METHOD, UNKNOWN WORD CONCEPT ESTIMATING DEVICE AND COMPUTER READABLE RECORD MEDIUM RECORDING UNKNOWN WORD CONCEPT ESTIMATION PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To unnecessitate modification analytical results as statistical information and to perform automatic processing by recursively executing and inter- word similarity calculation step and a similarity concept search step and estimating the concept of an unknown word. SOLUTION: An inter-word similarity calculating part 106 reads a neighborhood word statistical information stored in a neighborhood word statistical information storing part 105, also calculates the similarity between an unknown word inputted from an inputting part 103 and a node in a thesaurus 102 inputted from a similar concept searching part 107 based on the neighborhood word statistical information and outputs the similarity to the part 107. The part 107 searches for the node of a similar concept that resembles the inputted unknown word, tracing the link information of nodes of the thesaurus 102 having a concept that is from a higher one to a lower one, calls and executes the part 106 on all such occasions and estimates the concept of the unknown word.
