Book Description
The ninth campaign of the Cross-Language Evaluation Forum (CLEF) for European languages was held from January to September 2008. There were seven main eval- tion tracks in CLEF 2008 plus two pilot tasks. The aim, as usual, was to test the p- formance of a wide range of multilingual information access (MLIA) systems or s- tem components. This year, 100 groups, mainly but not only from academia, parti- pated in the campaign. Most of the groups were from Europe but there was also a good contingent from North America and Asia plus a few participants from South America and Africa. Full details regarding the design of the tracks, the methodologies used for evaluation, and the results obtained by the participants can be found in the different sections of these proceedings. The results of the CLEF 2008 campaign were presented at a two-and-a-half day workshop held in Aarhus, Denmark, September 17–19, and attended by 150 resear- ers and system developers. The annual workshop, held in conjunction with the European Conference on Digital Libraries, plays an important role by providing the opportunity for all the groups that have participated in the evaluation campaign to get together comparing approaches and exchanging ideas. The schedule of the workshop was divided between plenary track overviews, and parallel, poster and breakout sessions presenting this year’s experiments and discu- ing ideas for the future. There were several invited talks.

Book Description
In its ?rst ten years of activities (2000-2009), the Cross-Language Evaluation Forum (CLEF) played a leading role in stimulating investigation and research in a wide range of key areas in the information retrieval domain, such as cro- language question answering, image and geographic information retrieval, int- activeretrieval,and many more.It also promotedthe study andimplementation of appropriateevaluation methodologies for these diverse types of tasks and - dia. As a result, CLEF has been extremely successful in building a wide, strong, and multidisciplinary research community, which covers and spans the di?erent areasofexpertiseneededto dealwith thespreadofCLEFtracksandtasks.This constantly growing and almost completely voluntary community has dedicated an incredible amount of e?ort to making CLEF happen and is at the core of the CLEF achievements. CLEF 2010 represented a radical innovation of the “classic CLEF” format and an experiment aimed at understanding how “next generation” evaluation campaigns might be structured. We had to face the problem of how to innovate CLEFwhile still preservingits traditionalcorebusiness,namely the benchma- ing activities carried out in the various tracks and tasks. The consensus, after lively and community-wide discussions, was to make CLEF an independent four-day event, no longer organized in conjunction with the European Conference on Research and Advanced Technology for Digital Libraries (ECDL) where CLEF has been running as a two-and-a-half-day wo- shop. CLEF 2010 thus consisted of two main parts: a peer-reviewed conference – the ?rst two days – and a series of laboratories and workshops – the second two days.

Book Description
The pervasive creation and consumption of content, especially visual content, is ingrained into our modern world. We’re constantly consuming visual media content, in printed form and in digital form, in work and in leisure pursuits. Like our cave– man forefathers, we use pictures to record things which are of importance to us as memory cues for the future, but nowadays we also use pictures and images to document processes; we use them in engineering, in art, in science, in medicine, in entertainment and we also use images in advertising. Moreover, when images are in digital format, either scanned from an analogue format or more often than not born digital, we can use the power of our computing and networking to exploit images to great effect. Most of the technical problems associated with creating, compressing, storing, transmitting, rendering and protecting image data are already solved. We use - cepted standards and have tremendous infrastructure and the only outstanding ch- lenges, apart from managing the scale issues associated with growth, are to do with locating images. That involves analysing them to determine their content, clas- fying them into related groupings, and searching for images. To overcome these challenges we currently rely on image metadata, the description of the images, - ther captured automatically at creation time or manually added afterwards.

Book Description
This book constitutes the thoroughly refereed proceedings of the 10th Workshop of the Cross Language Evaluation Forum, CLEF 2010, held in Corfu, Greece, in September/October 2009. The volume reports experiments on various types of textual document collections. It is divided into six main sections presenting the results of the following tracks: Multilingual Document Retrieval (Ad-Hoc), Multiple Language Question Answering (QA@CLEF), Multilingual Information Filtering (INFILE@CLEF), Intellectual Property (CLEF-IP) and Log File Analysis (LogCLEF), plus the activities of the MorphoChallenge Program.

Book Description
The tenth campaign of the Cross Language Evaluation Forum (CLEF) for European languages was held from January to September 2009. There were eight main eval- tion tracks in CLEF 2009 plus a pilot task. The aim, as usual, was to test the perfo- ance of a wide range of multilingual information access (MLIA) systems or system components. This year, about 150 groups, mainly but not only from academia, reg- tered to participate in the campaign. Most of the groups were from Europe but there was also a good contingent from North America and Asia. The results were presented at a two-and-a-half day workshop held in Corfu, Greece, September 30 to October 2, 2009, in conjunction with the European Conference on Digital Libraries. The workshop, attended by 160 researchers and system developers, provided the opportunity for all the groups that had participated in the evaluation campaign to get together, compare approaches and exchange ideas.

This volume contains the papers presented at NLDB 2009, the 14th Inter- tional Conference on Applications of Natural Language to Information Systems held June 24–26, 2009, at the University of the Saarland and the German - search Center for Arti?cial Intelligence in Saarbruc ̈ ken, Germany. In addition to reviewed submissions, the program also included contributions to the doctoral symposiumheldduring NLDB2009aswellastwoinvitedtalks.Thesetalksc- ered some of the currently hot topics in the use of natural languagefor accessing information systems. Wereceived51submissionsasregularpapersforthemainconference,2extra submissions as posters, and 3 short papers for the doctoral symposium. Each paper for the main conference was assigned four reviewers, taking into account preferences expressed by the ProgramCommittee members as much as possible. Within the review deadline, we received at least three reviews for almost all submissions. After the review deadline, the Conference Organizing Committee members and the Program Committee Chair acted as meta-reviewers. This task included studying the reviews and the papers, speci?cally those whose assessment made them borderline cases, and discussing con?icting opinions and their impact on theassessmentofindividualpapers.Finally,themeta-reviewerswroteadditional reviews for the few papers which received less than three reviews, as well as for papers which received reviews with considerably con?icting assessments.

Book Description
The Internet has been acknowledged as a recent technological revolution, due to its significant impact on society as a whole. Nevertheless, precisely due to its impact, limitations of the current Internet are becoming apparent; in particular, its inability to automatically take into account the meaning of online documents. Some proposals for taking meaning into account began to appear, mainly the so-called Semantic Web, which includes a set of technologies like RDF that are based on new markup languages. Though these technologies could be technically sound, practical limitations, such as the high training level required to construct Semantic Web pages, and the small proportion of current Semantic Web pages make the Sematic Web marginal today and also in the near foreseeable future. Quantitative Semantics and Soft Computing Methods for the Web: Perspectives and Applications will provide relevant theoretical frameworks and the latest empirical research findings related to quantitative, soft-computing and approximate methods for dealing with Internet semantics. The target audience of this book is composed of professionals and researchers working in the fields of information and knowledge related technologies (e.g. Information sciences and technology, computer science, Web science, and artificial intelligence).
