Sammanfattning : Scientific applications require processing of high-volume on-line streams of numerical data from instruments and simulations. In order to extract information and detect interesting patterns in these streams scientists need to perform on-line analyses including advanced and often expensive numerical computations. LÄS MER
Sammanfattning : The ability to physically interconnect many distributed, autonomous and heterogeneous software systems on a large scale presents new opportunities for sharing and reuse of existing, and for the creataion of new information and new computational services. However, finding and combining information in many such systems is a challenge even for the most advanced computer users. LÄS MER
Sammanfattning : Many applications require storage and indexing of new kinds of data in main-memory, e.g. color histograms, textures, shape features, gene sequences, sensor readings, or financial time series. LÄS MER
Sammanfattning : The Semantic Web provides a framework for semantically annotating data on the web, and the Resource Description Framework (RDF) supports the integration of structured data represented in heterogeneous formats. Traditionally, the Semantic Web has focused primarily on more or less static data, but information on the web today is becoming increasingly dynamic. LÄS MER
Sammanfattning : Scientists who need to explore several different databases in theirresearch can find it difficult and tedious to extract and combineinformation from various heterogeneous data sources manually.This is a particular problem for researchers in the life sciences,since technical advances in the last decade have resulted in a dramaticincrease in the quantity and variety of data.
