This short paper is a work in progress describing our participation in the GRID@CLEF task. The GRID@CLEF task is intended to capture in XML form the intermediate results of the text processing phases of the indexing process used by IR systems. Our approach was to create a new instrumented version of the indexing program used with the Cheshire II system. Thanks to an extension by the organizers,...

In this paper we present a distributed spatial data warehouse system designed for storing and analyzing a wide range of spatial data. The data is generated by media meters working in a radio based measurement system. The distributed system is based on a new model called the cascaded star model. In order to provide satisfactory interactivity for our system, we used distributed computing supporte...

Indexing is the core component of most information retrieval systems, because it allows for a compact representation of the content of a collection of documents, aimed at efficient and scalable access and retrieval. Indexing techniques can be extended also to music, providing that significant descriptors are computed from music documents. These descriptors can be defined as the “lexical units” ...

Resource management and search is very important yet challenging in large-scale distributed systems like P2Pnetworks. Most existing P2P systems rely on indexing to efficiently route queries over the network. However, searches based on such indices face two key issues. First, majority of existing search schemes often rely on simply keyword based indices that can only support exact string based m...

NLM previously utilized two separate systems, the PubMed system and the Data Creation and Maintenance System (DCMS), for data management of PubMed citations. The PubMed system was managed by the National Center for Biotechnology Information (NCBI) with the purpose of storage and indexing of citation data for PubMed search. The role of the DCMS was then to facilitate data reviews and indexing of...
