This paper reports on the pilot question answering track that was carried out within the CLEF initiative this year. The track was divided into monolingual and bilingual tasks: monolingual systems were evaluated within the frame of three non-English European languages, Dutch, Italian and Spanish, while in the crosslanguage tasks an English document(More)
In this paper, we present our participation in the ImageCLEF 2005 ad-hoc track. First, we describe a preliminary pool of cross-language experiments with the ImageCLEF 2004 testbed performed in order to evaluate the impact of different-size dictionaries using three distinct approaches. These differences are not remarkable, however recognizing named entities(More)
This paper describes the procedure adopted by the three coordinators of the CLEF 2003 question answering track (ITC-irst, UNED and ILLC) to create the question set for the monolingual tasks. Despite the little resources available, the three groups collaborated and managed to formulate and verify a large pool of original questions posed in three different(More)
In this paper, we present FlickLing, a multilingual search interface for Flickr designed and implemented for the CLEF 2008 interactive task. FlickLing consists of two interfaces which allow to perform monolingual and multilingual image retrieval over the Flickr database, retrieving results with images annotated in different languages. From a given query(More)
This paper describes an empirical study of the “Information Synthesis” task, defined as the process of (given a complex information need) extracting, organizing and inter-relating the pieces of information contained in a set of relevant documents, in order to obtain a comprehensive, non redundant report that satisfies the information need. Two main results(More)
Participation in evaluation campaigns for interactive information retrieval systems has received variable success over the years. In this paper we discuss the large-scale interactive evaluation of multilingual information access systems, as part of the CrossLanguage Evaluation Forum evaluation campaign. In particular, we describe the evaluation planned for(More)
This paper summarizes the participation of UNED in the CLEF 2006 interactive task. Our goal was to measure the attitude of users towards cross-language searching when the search system provides the possibility (as an option) of searching cross-language, and when the search tasks can clearly benefit from searching in multiple languages. Our results indicate(More)
This paper summarises activities from the iCLEF 2009 task. As in 2008, the task was organised based on users participating in an interactive cross-language image search experiment. Organizers provided a default multilingual search system (Flickling) which accessed images from Flickr, with the whole iCLEF experiment run as an online game. Interaction by(More)
In this paper, we describe UNED’s participation in the iCLEF 2005 track. We have compared two strategies for finding an answer using an interactive question answering system: i) a search system over full documents and ii) a search system over passages (document’s paragraphs). We have added an interesting feature to both system in order to facilitate(More)
iCLEF 2004 is the first comparative evaluation of interactive Cross-Language Question Answering systems. The UNED group has participated in this task comparing two strategies to help users in the answer finding task: the baseline system is just a standard document retrieval engine searching machine-translated versions of the documents; the contrastive(More)
