Abstract
This invention improves information retrieval by providing a tokenizing apparatus and method that parses natural language text in a manner that increases the throughput of an information retrieval or natural language analysis system. The tokenizer includes a parser that extracts characters from the stream of text, an identifying element for identifying a token formed of characters in the stream of text that include lexical matter, and a filter for assigning tags to those tokens requiring further linguistic analysis. The tokenizer, in a single pass through the stream of text, determines the further linguistic processing suitable to each particular token contained in the stream of text.
