WORD LINKING IDENTIFICATION MODEL LEARNING DEVICE, WORD LINKING DETECTION DEVICE, METHOD AND PROGRAM

摘要

To provide a word linking identification model learning device, a word linking detection device, a method and a program capable of accurately learning an identification model which can identify whether or not linking of words is natural.SOLUTION: A word linking identification model learning device 100 comprises: a seed extraction unit 30 which performs a morphological analysis on a text collection in a predetermined domain, extracts, as a seed, a word string obtained by using a predetermined threshold from the result of the morphological analysis and defines the seed as positive example date; a negative example data expansion unit 34 which performs morphological analysis on a replacement character string in which words included in the seed are replaced, specifies a portion where linking of words in the replacement character string does not match an original part-of-speech string from the result of the morphological analysis and generates negative example data; and an identification learning model 36 which, on the basis of the positive example data and the generated negative example data, learns a word linking identification model 40 for identifying whether or not linking of words in the word string is natural.SELECTED DRAWING: Figure 1
