MuchMoreMultilingual Concept Hierarchies for Medical Information Organization and Retrieval The focus of our involvement in the MuchMore project for multilingual information access in medical information is on word sense disambiguation (WSD) and cross-language information retrieval (CLIR). During the first phase of the project, our work had two main directions: Co-authoring and editing a "State-of-the-Art Report" (for which particular thanks are due to Stefan Kaufmann) covering all major aspects of the MuchMore project, and the early stages of software development and experimental design for our part of the research. The State-of-the-Art Report provides a survey of the topics addressed in the project, existing results, techniques and evaluation standards, with special attention paid to their relevance to the project and its intended domain of application. It serves both to ensure that the project draws maximal benefit from previous work and available resources, thus avoiding duplication of work, and as a medium for the participants to share their expertise in their respective areas of strength in order to arrive at a common understanding of the nature and complexity of the tasks involved. The report is public-domain information and will be integrated in a larger, dynamically updated website for general accessibility. Meanwhile, it is available upon request from us. Thus we intend for it to serve as a resource and education material beyond the confines of the group of MuchMore participants. Our work on software development and experiment design has so far been at the preparatory stage. The work will involve extensive testing and evaluation of a number of linguistic and stochastic techniques, to which different sub-groups contribute. To facilitate this cooperation, we prepared the necessary computational infrastructure, defined standards for encoding and interfaces, and re-designed existing programs to comply with those standards. |
