Abstract
Online search retrieval is improved by automatic generation of key phrases. When a search engine crawls an electronic document, key words and phrases greatly help organize the electronic document to one or more topics. A quotient matrix defines a ratio of a key phrase to a total number of words in the electronic document. A correlation coefficient may also determine which key phrase correlates to the electronic document. A title key phrase may then be generated in response to the correlation coefficient having a positive value. When the search engine crawls the electronic document, the title key phrase may be provided as metadata.
