The PHOAKS system contains six months or more of recommendations and associated data for about 1,500 newsgroups.
PHOAKS searches messages for mentions of Web pages (URLs) and counts a mention as a recommendation if it passes a number of tests.
We obtained FAQs by tailoring the basic PHOAKS message-filtering architecture to identify Usenet messages that posted FAQs.
So far, we have used the PHOAKS architecture to recognize and process Web resource recommendations and FAQ messages.
The basic idea is to run a query using a normal keyword search engine, then filter the results through the databases maintained by PHOAKS.
