| Title: | PRE-COORDINATION + POST-COORDINATION = THE CASE FOR PARTIAL COORDINATION |

| Abstract: | The introduction of computerized post-coordination has solved many of
the problems of pre-coordinated subject access. However, the adoption of
computerized post-coordination results in the loss of some
precoordination benefits. Specifically, the effect of hiding terms
within the context of others is lost in post-coordination which gives
lead status to every document term, This results in spurious matches of
terms out of context. Library patrons and Internet searchers are
increasingly dissatisfied with subject access performance, in part
because of unmanageably large retrieval sets. The need to enhance
precision and limit the size of retrieval sets motivates this work which
proposes partial coordination, an approach which incorporates the
advantages of computer search with the ability of precoordination to
limit spurious partial matches and thereby enhance precision. |
