Abstract: Disclosed is a method, a computer program product and a system for processing documents that contain chemical names. The system has a unit to partition document text and to assign semantic meaning to words; a unit to recognize any substructures present in the chemical name fragments; and a unit to determine structural connectivity information of the chemical name fragments and recognized substructures and to store the determined structural connectivity information in a searchable index. The system further includes a unit to search a text index using at least one of a fragment name and a substructure name and to search the structure index by at least one of fragment connectivity and substructure connectivity. At an intersection of the search results from the structure index and the text index, the system operates to identify at least one document that contains a reference to a corresponding chemical compound.

Abstract: This invention provides a method, a system and a computer program for recognizing technical terms. In the preferred embodiment the technical terms are chemical names, and in a most preferred embodiment the technical terms are organic chemical names. A computer program product stores in a computer readable form a set of computer program instructions for directing at least one computer to process a text document. The set of computer program instructions include instructions for assigning corresponding associated parts of speech to words found in the document. The instructions for assigning include instructions to apply a plurality of regular expressions, rules and a plurality of dictionaries to recognize organic chemical name fragments, to combine recognized organic chemical name fragments into a complete organic chemical name, and to assign the complete organic chemical name with one part of speech.
