An entry selecting module selects as index entries only those strings which match one of those specialized words and notes the location(s) of each occurrence each index entry in the text. A printer outputs the selected index entries together with their occurrence positions. Each entry of the dictionary in the specialized field includes information concerning inflections and variants of that entry. The index is quickly and accurately generated by selecting index entries using a specialized dictionary relevant to a particular, specialized field. Since the selection of index entries is made by referring to such a dictionary, differences in criteria for selection used by different operators can be prevented. Since a specialized dictionary is prepared and updated for each field, the knowledge for generating an index is collected and shared by all the operators.Other References
