Abstract
The present invention provides a document processing apparatus, word extracting apparatus, word extracting method and storage medium for storing a word extracting program, capable of appropriately presenting effective associate words to the user. A retrieving element executes retrieval of documents based on a retrieval condition inputted through a retrieval condition inputting element. A keyword designating element designates an arbitrary word among the words included in the retrieved documents as an associate-word-searching word and designates other words as candidates for an associate word. A simultaneous appearance probability calculating element calculates a simultaneous appearance probability of the associate-word-searching word and one of the candidates for the associate word in any of the retrieved documents. A first independent appearance probability calculating element obtains an independent appearance probability of the associate-word-searching word in each of all documents. A second independent appearance probability calculating element calculates an independent appearance probability of each of the candidates for the associate word in each of all documents. A calculating element calculates the sum or product of the independent appearance probability of the associate-word-searching word and the independent appearance probability of each of the candidates for the associate word. An associate word extracting element extracts a word according to the ratio of the simultaneous appearance probability to the sum or product calculated by the calculating element.
