The computing power of present desktops is mostly unused under general office usage. These many computers can be unified into one grid, such that unused cycles can be scavenged to solve one computing task. Two software ...
ExpansionTool: Formal definition of concept-based query expansion and construction
(2001)
- report
We develop a deductive data model for concept-based query expansion. It is based on three abstraction levels: the conceptual, linguistic and string levels. Concepts and relationships among them are represented at the ...
Cumulated gain-based indicators of IR performance
(2002)
- report
Modern large retrieval environments tend to overwhelm their users by their large output. Since all documents are not of equal relevance to their users, highly relevant documents should be identified and ranked first for ...
The effects of separate and merged indexes and word normalization in multilingual CLIR

- report
Multilingual IR may be performed in two environments: there may exist a separate index for each target language, or all the languages may be indexed in a merged index. In the first case, retrieval must be performed separately ...
Query Performance Analyser - a tool for bridging information retrieval research and instruction
(Tampereen yliopisto, 2002)
- report
Information retrieval experiments usually measure the average effectiveness of IR methods developed. The analysis of individual queries is neglected although test results may contain individual test topics where general ...
