<P><FONT size=4>ESAIR’2009 is an ACM Workshop held in conjunction with </FONT><A
class=urlextern title=http://www.wsdm2009.org href="http://www.wsdm2009.org/"

Barcelona. </FONT></P>
<P><FONT size=4>After the success of the first ESAIR (</FONT><A class=urlextern
title=http://www.yr-bcn.es/esair08 href="http://www.yr-bcn.es/esair08"
rel=nofollow><FONT size=4>ESAIR'08</FONT></A><FONT size=4>), we’ve decided to
organize this workshop one more year. The goal of this workshop is to create a
forum for researchers interested in the use of semantic annotations for
information retrieval. By semantic annotations we refer to linguistic
annotations (such as named entities, semantic classes, etc.) as well as user
annotations such as microformats, <ACRONYM
title="Resource Description Framework">RDF</ACRONYM>, tags, etc. The aim of this
workshop is not semantic annotation itself, but rather the applications of
semantic annotation to information retrieval tasks such as ad-hoc retrieval,
classification, browsing, textual mining, summarization, question answering,
etc. </FONT></P>
<P><FONT size=4>In the recent years there has been a lot of discussion about
semantic annotation of documents. There are many forms of annotations and many
techniques that identify or extract them. As NLP tagging techniques mature, more
and more annotations can be automatically extracted from free text. In
particular, techniques have been developed to ground named entities in terms of
geo-codes, <ACRONYM
title="International Organization for Standardization">ISO</ACRONYM> time codes,
Gene Ontology ids, etc. Furthermore, the number of collections which explicitly
identify entities is growing fast with Web 2.0 and Semantic Web initiatives.
</FONT></P>
<P><FONT size=4>Despite the growing number and complexity of annotations, and
despite the potential impact that these may have in information retrieval tasks,
annotations have not yet made a significant impact in Information Retrieval
research or applications. Further research is needed before we can unleash the
potential of annotations! </FONT></P></DIV>
