There were two sets of problems addressed, which were
divided into the broad categories:
Where to Search and
How to Search.
There were also a few topics, namely Query Refinement,
that did not easily fit into our simple categorization, and weren't
discussed in the meeting.
We agreed on the basics of a format for centroids to enable query routing.
The general framework of the Whois++
Centroids specified in RFC 1913/1914
seemed appropriate enough,
although there was discussion as to shortcomings of those standards in
relation to general databases vs White Pages (e.g. there are currently
no provisions for flags describing the centroid as being created
using stemming or stop lists).
Alternatively, the informal agreement that Stanford is coordinating
proposes centroids
that include the content summaries that we agreed upon (i.e., the
words in the collection plus their document frequencies), together
with information about stemming and stop words, for example.
