%X This paper contains the details of how one canextract person name, date and place from a textdocument using finite state automata and LEX tool.If we search a text document for some importantinformation manually, the process is slow, tediousand error prone. The regular expressions are usedto parse textual data to match patterns and extractvariables. The lexical analyzer is used in thisresearch, which scans the input program characterby character and groups them together to formtokens. This paper describes a technique to performidentification and extraction of information byusing LEX tool. It finds the names, date and placesthat appear in machine-readable text document.Regular expressions through which requiredinformation is extracted are also discussed.
