    <pub:abstract><![CDATA[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.
Such categories offer a standardized and universal
way for referring to or describing the nature of real
world objects, activities, documents and so on, and
may be used (we suggest) to semantically characterize
the content of documents. WWW indices,
like Yahoo! provide a huge hierarchy of categories
(topics) that touch every aspect of human endeavors.
Such topics can be used as descriptors, similarly
to the way librarians use for example, the
Library of Congress cataloging system to annotate
and categorize books.
<p>
In the course of investigating this idea, we address
the problem of automatic categorization of webpages
in the Yahoo! directory. 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
and the webpages to be categorized. Our
findings suggest that the best results occur when
using the very brief descriptions of the Yahoo! categorized
entries; these brief descriptions are provided
either by the entries' submitters or by the Yahoo!
human indexers and accompany most Yahoo!-
indexed entries.]]></pub:abstract>
