A text cataloging method includes a step of cataloging already-analyzed-text data obtained from an analysis of a logical structure of a text to be cataloged in a text database, a step of creating a structure index by sequentially superposing logical structures of texts to be cataloged, wherein a single metaelement is used for representing a group of elements in the texts having the same position of appearance in one of the texts and the same element type, a single piece of meta-character-string data is used for representing a group of pieces of character-string data in the texts having the same position of appearance in one of the texts, and a context identifier is assigned to each metanode composing a tree-like structure of the structure index for uniquely identifying the metanode; a step of generating structured-full-text data composed of definitions of associative relations between all pieces of character-string data included in already-analyzed-text data of each text to be cataloged, and context identifiers of pieces of meta-character-string data in the structure index used for representing the pieces of character-string data; and a character-string-index updating step, including the sub-steps of extracting partial character strings, generating structured-character-position information, and updating a character-string index.

1. In a structured-text cataloging method for a text searching system in which a set of texts is searched for specific text contents, a character-string-index updating step comprising the sub-steps of:extracting partial character strings each having a predetermined character count, character-position information of said partial character strings in a text to be cataloged, a text identifier for uniquely identifying said text in a text database, and a context identifier of a metanode representing character-string data including said partial character strings in a structure index, from said character-string data included in said text for each of a plurality of texts to be cataloged; generating structured-character-position information that includes said character-position information, said text identifier, and said context identifier; and updating a character-string index by cataloging an associative relation between each of said partial character strings and said structured-character-position information in said character-string index.
