These proceedings contain the papers presented at ECIR 2009, the 31st European
Conference on Information Retrieval. The conference was organized by
the Institut de Recherche en Informatique de Toulouse (IRIT), in cooperation
with the Information Retrieval Specialist Group of the British Computer Society
(BCS-IRSG) and was supported by the Special Interest Group on Information
Retrieval (ACM SIGIR), the French Association of Information Retrieval
(ARIA) and E-IRSG. It was held during April 6–9, 2007 in Toulouse, hosted by
the Pierre Baudis congress center.
ECIR 2009 confirmed the growth trend of submissions, with 188 full-paper
submissions.
Many of these submissions came from outside Europe, and 25 countries were
represented in the final ECIR 2009 program, reflecting the international popularity
and reputation of the conference series. Furthermore the traditional strong
focus on students was well preserved, with their participation being great.
All submitted papers were reviewed by at least three members of the international
Program Committee. Out of the 188 papers 42 were selected as full
research papers and a further 18 were accepted as short research papers. Short
papers were given 8 pages in the proceedings (instead of 12). Out of these 60
selected papers, 30 have a student as the primary author. The accepted papers
themselves come from a mixture of universities, research institutes and commercial
organizations.
There was also a separate call for posters. Each of the 60 poster submissions
was reviewed by three Program Committee members, as with paper submissions.
Twenty-five posters were accepted for presentation.
Taken together, these papers cover the state of the art in information retrieval,
including topics such as retrieval models, evaluation andWeb search, and emerging
topics such as learning to rank, expert search and opinion detection.
The success of such a conference is not possible without the huge effort
of several people and organizations. We owe a great thanks to our various
committees—Program and Poster Committees, Tutorial and Workshop Committee
and Award Committees—for their hard work in ensuring the quality of
the ECIR 2009 program. We really appreciate the support, the expertise and
the effort given so freely. We thank the researchers who submitted their results,
and the members of the local Organizing Committee for their hard work over
many months.
We also thank our sponsoring institutions, Google, Matrixware Information
Services, Microsoft Research, Yahoo! Research, Exalead, GDR I3, Universit´e
Paul Sabatier, ARIA, Inforsid and R´egion Midi-Pyr´enn´ees for their support of
ECIR 2009. |
