Abstract
An information processing apparatus to select a token from a document to describe a field of interest includes an obtaining unit, a determining unit, a clustering unit, and a selecting unit. The obtaining unit obtains a list of tokens output from extractors that received the document as an input. Each output token has an extractor score assigned to by an extractor. The determining unit determines, as a word frequency value, a frequency of each word in the list of tokens, determines a token score for each token in the list of tokens, and determines a distance between each token in the list of tokens. The clustering unit clusters each token in the list of tokens into a plurality of groups. The selecting unit selects a token with a group of the plurality of groups to describe the field of interest in the document.
