Vague Transformations in Information Retrieval
Information Retrieval (IR) is often confronted with different and heterogeneous collections of multilingual and multimedial content. Transformations are necessary in order to map between different representation schemes which are the result of different content analysis methods and different terminologies. Vague methods which have been sucessfully applied to IR seem especially suited to tackle ...
متن کاملInformation Measure for Vague Symbols*
The structures of the fuzzy information theory are focused on the concept of fuzzy entropy, where the individual information of symbols is considered only implicitely. This paper aims to fill this gap and to study the concepts of fuzzy information. Special attention is paid to the typical fuzzy set theoretical paradigma of monotonicity of operations.
متن کاملEntropies of vague information sources
The information-theoretical entropy is an effective measure of uncertainty connected with an information source. Its transfer from the classical probabilistic information theory models to the fuzzy set theoretical environment is desirable and significant attempts were realized in the existing literature. Nevertheless, there are some open topics for analysis in the suggested models of fuzzy entr...
متن کاملInformation in Vague Data Sources
This paper deals with the concept of the “size” or “extent” of the information in the sense of measuring the improvement of our knowledge after obtaining a message. Standard approaches are based on the probabilistic parameters of the considered information source. Here we deal with situations when the unknown probabilities are subjectively or vaguely estimated. For the considered fuzzy quantiti...
متن کاملEfficient Vague Joins Processing in the VQS
Joins are among the most expensive operations in database management systems (DBMSs). In the context of the VQS (Vague Query System), which is a flexible query answering system built on top of DBMSs to provide them with similarity search/retrieval capabilities, vague joins are prohibitively expensive in terms of both IO-cost and CPU-cost because they must undergo intermediate processing steps w...
