By Cathal Gurrin

These court cases comprise the papers provided at ECIR 2010, the thirty second ecu- pean convention on details Retrieval. The convention was once organizedby the information Media Institute (KMi), the Open college, in co-operation with Dublin urban collage and the collage of Essex, and was once supported through the knowledge Retrieval professional workforce of the British desktop Society (BCS- IRSG) and the precise curiosity staff on details Retrieval (ACM SIGIR). It used to be held in the course of March 28-31, 2010 in Milton Keynes, united kingdom. ECIR 2010 got a complete of 202 full-paper submissions from Continental Europe (40%), united kingdom (14%), North and South the USA (15%), Asia and Australia (28%), center East and Africa (3%). All submitted papers have been reviewed by means of at leastthreemembersoftheinternationalProgramCommittee.Outofthe202- pers forty four have been chosen asfull researchpapers. ECIR has alwaysbeen a convention with a powerful pupil concentration. to permit as a lot interplay among delegates as attainable and to maintain within the spirit of the convention we determined to run ECIR 2010 as a single-track occasion. for this reason we made up our minds to have presentation codecs for complete papers. a few of them have been awarded orally, the others in poster structure. The presentation structure doesn't signify any di?erence in caliber. as a substitute, the presentation layout used to be made up our minds after the total papers have been permitted on the application Committee assembly held on the college of Essex. The perspectives of the reviewers have been then considered to choose the main acceptable presentation layout for every paper.

57 By Topic. For the best-performing configuration of each method (as given in Table 1), we compute retrieval-effectiveness measures at cut-off level k = 10 and group them by topic. Table 2 shows the resulting figures. These support our above observations. In addition, we observe that all methods perform worst on queries from Technology. The best performance varies per method and measure. Table 3. 35 By Temporal Granularity. In analogy, we can group retrieval-effectiveness measurements at cut-off level k = 10 by temporal granularity – again considering only the best-performing configuration of each method.
