Computing text semantic relatedness using the contents and links of a hypertext encyclopedia

Andrei Popescu-Belis, Majid Yazdani

We propose a method for computing semantic relatedness between words or texts by using knowledge from hypertext encyclopedias such as Wikipedia. A network of concepts is built by filtering the encyclopedia's articles, each concept corresponding to an artic ...
