Yahoo! as an ontology
1999
Proceedings of the eighth international conference on Information and knowledge management - CIKM '99
Preserved Fulltext
We suggest that one (or a collection) of names of Yahoo! (or any other WWW indexer's) categories can be used to describe the content of a document. ...
We use Telltale as our classifier; Telltale uses n-grams to compute the similarity between documents. We experiment with various types of descriptions for the Yahoo! ...
categories, our larger point is that Yahoo! categories can be used as a standardized way for referring to or describing the "nature" of things. ...

The fundamental idea behind this work is to exploit an ontology hierarchical structure in order to find a topic of a text. ...
This situation forces us to extend the ontology by enriching each of its concepts with new concepts using the external linguistics knowledge-base (WordNet). ...
These retrieved words from WordNet will be treated as the extension of Yahoo hierarchy. The enrichment of Yahoo concept using WordNet words is not as easy as seen. ...
