This presentation introduces a suite of web-based English lexical knowledge resources, called StringNet and StringNet Navigator
(http://nav.stringnet.org), designed to provide access to the immense territory of multiword expressions that falls between what the lexical
entries encode in lexicons on the one hand and what productive grammar rules cover on the other. StringNet’s content consists of 1.6 billion
hybrid n-grams, strings in which word forms and parts of speech grams can co-occur. Subordinate and super-ordinate relations among hybrid
n-grams are indexed, making StringNet a navigable web rather than a list. Applications include error detection and correction tools and
web browser-based tools that detect patterns in the webpages that a user browses.
