The NLP Task at INEX 2005

Woodley, Alan P. & Geva, Shlomo (2006) The NLP Task at INEX 2005. SIGIR Forum, 40(1), pp. 60-63.


With XML information retrieval, like in traditional IR, the user's information need
is loosely defined, linguistic variations are frequent, and answers are a ranked list
of relevant elements. Like in database querying, structure is of importance and a
simple list of keywords may not be sufficient to define an XML query. Structured
query languages for XML have been developed, but appear to be difficult to use
even by system-level users, let alone end-users. Therefore developing natural
language interfaces for XML-IR requires innovative solutions.
INEX provides a framework (documents, topics and relevance assessments) for
independent evaluation of XML-IR systems and approaches. In 2002 and 2003
systems in the Ad-hoc task accepted formal language queries (i.e. <title>
elements) and produced results lists of relevant XML elements (usually well below
the document root). In 2004 INEX introduced a Natural Language Processing task
that operated in parallel with the Ad-hoc task (using the same topics and
assessments) except that systems operated on XML natural language queries (i.e.
<description> elements).
In this report we describe the motivation for using NLP in XML IR, the general
approaches that were tested at INEX 2005, and comment on the results.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
