Abstract: PURPOSE: To sort documents based on the contents of a sentence by considering not only the probability of a word but also the relation between adjacent words at the time of obtaining the probability of sorting documents, thereby allowing each of them to obtain the probability of sorting the pertinent document into some document group. CONSTITUTION: When data for calculating sorting probability is accumulated by sorting probability accumulation processing, a document is newly inputted to a new document input part 6. A morphemic analyzing part 7 divides the inputted document to be the units of sentences and then morphemic-analyzes it to extract words. A sorting item extracting part 8 extracts the word, adjacent two words and three words to be sorting items from the obtained words. A sorting probability extracting part 9 selects one sorting group to be the candidate of sorting from among all the sorts. Then a sorting probability calculation part 10 extracts, with respect to the extracted sorting items, the probability of making each of them in the sorting group from a probability accumulation part 14.  In addition, the probability of sorting the document to be in some sort is individually calculated through the use of the sorting probability of the sorting items.
