Simon Sandstone (Cambrian). A hydrogeological model with comprehensive characterization of uncertainties is needed to predict the behavior of CO2 and the risk of leakage. To start, ArcGIS was used to construct a 3-D model

A large effort went into the construction of a geographic thesaurus which was utilized to add geographic knowledge to the documents and queries. Geographic filtering was applied to the results returned from a retrieval by content run. Employing such a geographic knowledge base however showed no added value - the content-only baseline outperformed all geographically filtered runs.

MapReduce for Information Retrieval Evaluation: “Let’s Quickly Test This on 12 TB of Data”

We present a small case study in which we use a cluster of 15 low cost machines to search a web crawl of 0.5 billion pages showing that sequential scanning is a viable approach to running large-scale information retrieval experiments with little effort. The code is available to other researchers at: http://mirex.sourceforge.net

CLEF 2007: Ad Hoc Track Overview

The track was divided into two streams. The main stream offered mono-and bilingual tasks on target collections for central European languages (Bulgarian, Czech and Hungarian). Similarly to last year, a bilingual task encouraging system testing with non-European languages against English documents was also offered; this year, particular attention was given to Indian languages. The second stream, designed for more experienced participants, offered mono-and bilingual "robust" tasks with the objective of privileging experiments which achieve good stable performance over all queries rather than high average performance. These experiments re-used CLEF test collections from previous years in three languages (English, French, and Portuguese). The performance achieved for each task is presented and a statistical analysis of results is given.

Problematic cases arise due to the fact that each site re-used different resources and because the core vocabulary of the wordnets show complex properties. Many of these cases are discussed with respect to language internal and equivalence relations. Possible solutions are given in the form of additional criteria.

However, limitations in information and communication technologies have so far prevented the average person from taking much advantage of existing resources. Historical documentaries held by national archives constitute some of the most precious yet least accessible cultural information. The ECHO project has facilitated accessibility to this type of precious information by developing a digital library (DL) service for historical films belonging to large national audiovisual archives.

The first approach indexes documents and queries in terms of the EuroWordNet Inter-Lingual-Index, thus turning term weighting and query/document matching into language-independent tasks. The second describes

MultiMatch is a 30 month specific targeted research project under the Sixth Framework Programme, supported by the unit for Content, Learning and Cultural Heritage (Digicult) of the Information Society DG. MultiMatch plans to develop a multilingual search engine designed specifically for the access, organization and personalized presentation of cultural heritage information. This paper provides an overview of the project goals and describes the preliminary results.

In contrast to the standard Quartz Crystal Monitor (QCM), the LFE sensor surface allows one to sensitively monitor both mechanical and electrical property changes in adjacent media or analyte selective biological or chemical films. Although LFE
