Abstract
Abstract An apparatus for creating an index of coded textual data includes a textual data storage (20) for storing coded textual data, a text analyzing module (32) for analyzing the textual data stored in the textual data storage (20) to divide the textual data into a plurality of meaningful strings, a dictionary (40) in specialized field for storing a set of specialized words in a field of knowledge related to the textual data, an entryselecting module (36) for selecting as index entries only strings having equivalents in the set of specialized words by referring to the set of specialized words and for pairing the same with its occurrence position to store the same, and a printer (10) for outputting the selected index entries together with their occurrence positions. Each entry of the dictionary (40) in specialized field includes information concerning inflexions and variants. Generation of an index can be accurately performed in a short time by the selection of index entries by referring to the dictionary (40) in specialized field. Since the selection of index entries is made by referring to the dictionary (40), difference in criteria for selection caused by operators can be prevented. Since a dictionary (40) is prepared and updated for each field, the knowledge for generating an index is collected and shared by all the operators.
