ECIR is theannualconferenceoftheBritishComputerSociety’sspecialistgroupinInf- mation Retrieval. This yr the convention used to be held on the tuition of Computing and know-how on the college of Sunderland. ECIR all started existence because the - nual Colloquium on info Retrieval learn. The colloquium was once held within the united kingdom every year till 1998 while the development used to be held in Grenoble, France. considering then the convention venue has alternated among the uk and Continental Europe, and the development was once renamed the eu convention on info Retrieval. lately, ECIR has persevered to develop and has turn into the foremost ecu discussion board for the dialogue of analysis within the ?eld of knowledge Retrieval. To mark this metamorphosis from a small casual c- loquium to a big occasion within the IR learn calendar, the BCS-IRSG made up our minds to rename the development to the ecu convention on info Retrieval. ECIR2004received88fullpapersubmissions,fromacrossEuropeandfurther a?eldincludingNorthAmerica,ChinaandAustralia,atestamenttothegrowing acceptance and popularity of the convention. Out of the 88 submitted papers, 28 have been authorized for presentation. All papers have been reviewed via at the least 3 reviewers. one of the authorised papers eleven have a pupil because the basic writer, illustrating that the conventional pupil concentration of the unique colloquium is alive today.

This quantity comprises the lawsuits of the 15th Colloquium on timber in Algebra and Programming. The papers chosen current new learn effects and canopy the next subject matters: - Logical, algebraic and combinatorial homes of discrete constructions (strings, timber, graphs, and so on. ), together with the idea of formal languages regarded as that of units of discrete constructions and the speculation of rewriting platforms over those items.

However, and quibbles aside, this approach has now even suggested considering questionanswering as a form of translation (as it been seen as a form of IR for quite a while) and in that case the asymmetry is not so striking (see [5]). All this work remains statistical, as indeed is so much of NLP and AI these days, but there is clearly an element here of NLP techniques, however construed, being applied to IR (rather than the reverse) even if much of this is achieved by a widening or redefinition of the core IR task itself.
