Title:   GalaTex, a full-text search extension to XQuery
Speaker: Emiran Curtmola

Abstract:

While current XML query processing languages, XPath 2.0 and XQuery 1.0
which are the W3C recommended standards for querying XML documents,
operate on structured XML data, they are limited in expressing
full-text queries. Recently, there is a new emerging standard proposed
by the W3C to extend XPath and XQuery with complex full-text search
queries by providing a set of composable predicates such as phrase
matching, boolean connectives, proximity distance, stemming and
thesauri.
In this talk, I will present GalaTex, a conformance implementation of the
W3C XQuery Full-Text proposal that extends Galax, the AT&T
XPath/XQuery implementation. I will describe the architecture of GalaTex,
its data model, its search primitives, the match options such as stemming,
stopwords, regular expressions and also different possible evaluation
strategies for XQuery Full-Text.
