Subject: Relevance Searching
Date: Mon, 6 Dec 1993 23:29:35 -0800 (PST)
The following is a copy of a correspondence between bnb@math.ams.org
and myself. The context of the discussion was the standardization of
TeX/LaTeX to facilitate an information retrieval (i.e., electronic
literature search) system implemented via an inverted index. I think
the concept of the relevance search schema may be relevant to this
discussion, although any discussion of the standardization of
TeX/LaTex would be inappropriate here, and should be directed to
comp.text.tex.
