چکیده

University of Tampere (UTA) and Swedish Institute of Computer Science (SICS) joined forces in a CLEF-IP experiment where a simple automatic query generation approach was initially tested. For two topics, the extracted query words were compared to query keys selected by three human experts to see whether the automatic key word extraction algorithms seem to be able to extract relevant words from the topics. We participated in the main task with 8 XL runs. Despite the modesty of our results, our best runs placed relatively well compared to the other participants’ runs. This suggests that our approach to the automatic query generation could be useful, and should definitely be developed further. The comparison of the queries generated by the patent engineers to those generated by our system showed that typically less than half of the query words selected by the patent engineers were present in the automatically generated queries. For the limited two topics, our automatically generated queries also performed better than the patent engineers’ ones, but clearly more user data would be needed before any conclusions can be made in one way or another.

SICS at iCLEF 2008: User Confidence and Satisfaction Tentatively Inferred from iCLEF Logs

This paper gives a brief description of some initial experiments performed at SICS using the interactive image search query logs provided for participants in the interactive track of CLEF. The SICS experiments attempt to establish whether user confidence and trust in results can be related to logged behaviour. SICS has participated in this year’s iCLEF cycle mainly with an eye on future experim...

SICS at iCLEF 2008: User Confidence and Satisfaction inferred from iCLEF Logs

SICS has participated in this year’s iCLEF cycle mainly with an eye on future experimental settings to work on measurement of searcher trust and confidence in the search process and its results, in keeping with previous experimental studies performed at SICS [2, e.g.]. SICS has used the Flickling interface [1] and the logs delivered by it to study how searcher actions can be interpreted as expo...

Trusting the Results in Crosslingual Keyword-based Image Retrieval

This paper gives a brief description of the starting points for the experiments the SICS team has performed in the 2006 interactive CLEF campaign. Our experiments attempted to coax out social behaviour out of assessing usefulness of images for the illustration of a text, but found that the experiment design was not sensitive enough to find reliable results. 1

Dictionary-based Amharic-French Information Retrieval

We present four approaches to the Amharic French bilingual track at CLEF 2005. All experiments use a dictionary based approach to translate the Amharic queries into French Bags-of-words, but while one approach uses word sense discrimination on the translated side of the queries, the other one includes all senses of a translated word in the query for searching. We used two search engines: The SI...
