Abstract: Provided are a correlation determination unit to set, as a first apparatus, one apparatus among a plurality of apparatuses, set, as a first quality value, a quality value indicating a quality of an intermediate product processed by the first apparatus, set, as a second apparatus, an apparatus among the plurality of apparatuses that belongs to a process prior to the process to which the first apparatus belongs, set, as a second quality value, a quality value of an intermediate product processed by the second apparatus and determine whether correlation exists between the first quality value and the second quality value; a set determination unit to determine, using a quality standard value BQ indicating a standard of quality of the intermediate product, whether the first apparatus and the second apparatus are a set of apparatuses for which a first error between the first quality value and the quality standard value BQ and a second error between the second quality value and the quality standard value BQ cancel ea

Abstract: A device and method to estimate a word sense with high accuracy by unsupervised learning. A word sense estimation device executes a plurality of number of times a probability calculation of calculating an evaluation value for each word of a case where each concept extracted as a word sense candidate is determined as a word sense, based on a proximity between a context feature of a selected word and a context feature of another word, a proximity between a selected concept and a word sense of this another word, and a probability that the selected word takes a selected word sense, and of re-calculating the probability based on the evaluation value calculated, and estimates a concept with a higher probability calculated of said each word, to be a word sense of the word.
