Risk-Aware Information Retrieval
Probabilistic retrieval models usually rank documents based on a scalar quantity. However, such models lack any estimate for the uncertainty associated with a document’s rank. Further, such models seldom have an explicit utility (or cost) that is optimized when ranking documents. To address these issues, we take a Bayesian perspective that explicitly considers the uncertainty associated with th...
متن کاملApplication of Geometrical Approaches to Information Retrieval
In this paper we propose an idea of transformation relational database problems to computational geometry problems to develop more efficient algorithms for discovering useful information from databases. We consider in detail relational algebra operations the base of relational language foundation and give adequate geometrical interpretation for each of them.
متن کاملSome Non-traditional Approaches to Information Retrieval
In this brief overview of the projects I've worked on, I'd like brieey to describe several approaches to information retrieval which push on the traditional boundaries in various ways in order to provide practical solutions to some of the real challenges facing information retrieval systems. These \experiments", which have often used existing (or borrowed) techniques in sometimes unexpected way...
متن کاملChapter 1 COMBINING APPROACHES TO INFORMATION RETRIEVAL
The combination of different text representations and search strategies has become a standard technique for improving the effectiveness of information retrieval. Combination, for example, has been studied extensively in the TREC evaluations and is the basis of the “meta-search” engines used on the Web. This paper examines the development of this technique, including both experimental results an...
متن کاملDifferent approaches to Cross Language Information Retrieval
This paper describes two experiments in the domain of Cross Language Information Retrieval. Our basic approach is to translate queries word by word using machine readable dictionaries. The first experiment compared different strategies to deal with word sense ambiguity: i) keeping all translations and integrate translation probabilities in the model, ii) a single translation is selected on the ...
