The present invention is a method and system for the extraction of keyphrases from natural text. For the purpose of this document, keyphrases are text segments that represent the main topic of a text. The method of the present invention may facilitate keyphrase extraction from any length of text. The text may be of several varieties, such as, for example a sentence, paragraph, document or collection of documents. Phrase separator methods may be applied to the text to extract phrases from the text. From these phrases the present invention may identify the one or more phrases that are integral to the meaning of the text and these may be identified as the keyphrases of the text. The text may be indexed using the keyphrases so that a search based upon any of the keyphrases will cause search engines and/or text retrieval means to retrieve the text.

A trinary bar code and a device for reading and decoding said bar code are described. A predetermined number of bar code elements on a substrate makes up each character of data. Each bar code element is selected from a group comprising a first element in the form of a bar having a first length, a different sensibility than the substrate, and a given width; a second element in the form of a bar having a different length than said first element, a different sensibility than said substrate, and a width substantially the same as said given width; and a third element in the form of a space having a width substantially the same as said given width and having the sensible characteristic of said background. The device for reading and decoding the bar code includes a plurality of sensors, a corresponding plurality of flip flops to which the sensors are coupled, gates connected to the flip flops to provide combinations of signals from the flip flops, a group of latches coupled to the gates and equal in number to the number of bar code elements per character, a control circuit to cause the latches sequentially to store data corresponding to the sequential sensing of the bar code elements; and a decoding circuit coupled to the latches to decode the latched data to output the encoded character.
