Semantic and Conceptual Context-Aware Information Retrieval
This paper presents an information retrieval methodology which uses Formal Concept Analysis in conjunction with semantics to provide contextual answers to Web queries The conceptual context defined in this article can be global i.e. stableor instantaneousi.e. bounded by the global context. Our methodology consists first in a pre-treatment providing the global conceptual context and then in an o...
متن کاملBridging Semantic Gaps in Information Retrieval: Context-Based Approaches
In Information Retrieval (IR), the semantic gap is the difference between what computers store and what users expect via their queries. There are several reasons for the existence of those gaps such as homonymy and synonymy in text retrieval, or the typical difference between low-level representations and keyword-based queries in image retrieval. The objective of this work is to close these gap...
متن کاملInformation Retrieval in Context
The situations in which we search form a context: a complex set of variables describing our intentions, our personal characteristics, the data and systems available for searching, and our physical, social and organizational environments. Different contexts can mean that we want search systems to behave differently or to offer different responses. Creating search systems and search interfaces to...
متن کاملSemantic Rules for Context-Aware Geographical Information Retrieval
Geographical information retrieval (GIR) can benefit from context information to adapt the results to a user’s current situation and personal preferences. In this respect, semantics-based GIR is especially challenging because context information – such as collected from sensors – is often provided through numeric values, which need to be mapped to ontological representations based on nominal sy...
متن کاملSemantic processing in information retrieval.
Intuition suggests that one way to enhance the information retrieval process would be the use of phrases to characterize the contents of text. A number of researchers, however, have noted that phrases alone do not improve retrieval effectiveness. In this paper we briefly review the use of phrases in information retrieval and then suggest extensions to this paradigm using semantic information. W...
