Query reformulation with collaborative concept-based expansion
Most information retrieval systems on the Internet try to supply the ‘best’ documents to a certain query by ranking the complete hit list with various algorithms. But this is only appropriate if the hit list contain relevant documents which can be positioned on the top. In the case of a small or empty hit list no ranking can improve the result and the user must reformulate the query again and a...
متن کاملContextual and Concept-Based Interactive Query Expansion
In this paper, we present a novel approach for contextual and concept based query formulation in web-based information retrieval, which is an on-going PhD project being undertaken at the Software Engineering Research Lab (SERL) at Auckland University of Technology (AUT). Various query formulation approaches have been studied for a long time with varying degree of success. To the best of our kno...
متن کاملConcept-based Query Expansion and Construction
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 conceptual level. The linguistic level gives natural language expressions for concepts. Each expression has one or more matching patterns at the string level. The models specify th...

متن کاملDesign concept of K-DEMO for near-term implementation
A Korean fusion energy development promotion law (FEDPL) was enacted in 2007. As a following step, a conceptual design study for a steady-state Korean fusion demonstration reactor (K-DEMO) was initiated in 2012. After the thorough 0D system analysis, the parameters of the main machine characterized by the major and minor radii of 6.8 and 2.1 m, respectively, were chosen for further study. The a...
