Abstract: A system and method for facilitating the accurate entry of information into a highly structured database by initially extracting information from a plurality of nonuniformly formatted source data streams, e.g., documents/files, and subsequent interactions with users before storing the accepted and/or modified information into the database. Embodiments of the present invention provide an interactive path for each user (e.g., the author of the source document/file) to interactively modify the extracted data, e.g., according to the source document/file. Preferably, this interactive path is provided via the Internet and the extracted information can be modified by editing and/or selectively copying portions of the source documents/files to supplement and/or modify the extracted information.

Abstract: A system, method, and computer program for automatically generating text analysis systems is disclosed. Individual passes of a multi-pass text analyzer are created by generating rules from samples supplied by users. Successive passes are created in a cascading fashion by performing partial text analyses employing existing passes. A complete text analyzer interleaves the generated passes with a framework of existing passes. The complete text analysis system can then process texts to identify patterns similar to samples added by users. Generation of rules from samples encompasses a wide range of constructs and granularities that occur in text, from individual words to intrasentential patterns, to sentential, paragraph, section, and other formats that occur in text documents.
