Abstract

this article, we describe an algorithm for assigning Web directories (from the Open Directory Project #http://dmoz.org#) as characterizations for word senses in WordNet 1.7 noun synsets (Miller 1990). For instance, let us consider the noun circuit, which has six senses in WordNet 1.7. These senses are grouped in synsets, together with their synonym terms, and linked to broader (more general) synsets via hypernymy relations: 6 senses ofcircux Sense 1:{circux( electricalcircuri electric circuic => {electrical device} Sense 2:{toux circuDx =>{jou&&x( jou&&x(]NX Sense 3:{circux( => {path, rouh, itinerary} Sense 4:{circux (jucux( division)} =>{grouO grouO.( Sense 5: {racing circug( circug( => {racetrack, racecouck, raceway, track} Sense 6: {lap, circle, circu,( => {locomotion, travel} Our algorithm associates circuit 1 (electric circuit) with ODP directories such as bu.AAN(]R&O`(uu`(uuuNDX and 487 whereas circuit 5 (racing circuit) is tagged with directories such as sports/motorsports/auD racing/tracks sports/equks(D&&XX(]X"OD(uX( sports/motorsports/au` racing/formup one Every ODP directory has an associated URL, which contains a description of the directory and a number of Web sites that have been manually listed as pertaining to the directory topic, accompanied by brief descriptions of each site. This information is completed with a list of subdirectories, each containing more Web sites and subdirectories. Finally, some directories also have pointers to the same category in other languages. For instance, the Web page for the directorysports/motorsports/auu racing/tracks can be seen in Figure 1. This directory contains links and descriptions for 846 Web sites organized in 12 subdirectories, a link to a related directory (sports/motorsports/kartin...
