Evaluation of interactive cross-lingual information retrieval systems has been the focus of recent research. The goal is to support the users in formulating effective queries and selecting the documents which satisfy their information needs regardless of the language of the documents. This dissertation aims at harnessing the user-system interaction, extracting the added value and integrating it...

Several mathematical ideas have been investigated for Quantitative Information Flow. Information theory, probability, guessability are the main ideas in most proposals. They aim to quantify how much information is leaked, how likely is to guess the secret and how long does it take to guess the secret respectively. In this work we investigate the relationship between these ideas in the context o...

The Web has become the most important information source for most of us. Unfortunately, there is no guarantee for the correctness of information on the Web. Moreover, different websites often provide conflicting information on a subject. Several truth discovery methods have been proposed for various scenarios, and they have been successfully applied in diverse application domains. In this paper...

The concept of "relevance" is the fundamental concept of information science in general and information retrieval, in particular. Although "relevance" is extensively used in evaluation of information retrieval, there are considerable problems associated with reaching an agreement on its definition, meaning, evaluation, and application in information retrieval. There are a number of different vi...

Information Systems Discipline (ISD) is dominated by the two contrary paradigms of design science on the one hand and behavioral science on the other. Apart from that, research results are considered more or less relevant for practice depending on the respective paradigm. Conclusively, research communities following the paradigms are partly incompatible while, due to the notion of relevance for...

An increasing data overload makes it difficult to deliver needed information to knowledge-workers and decision-makers in process-oriented enterprises. The main problem is to identify information being relevant for process participants and their activities. To cope with this challenge, enterprises crave for an intelligent and processoriented information logistics. The major challenge is to provi...

Purpose – Explores the relevance of structuralism and post-structuralism to the field of library and information science (LIS). Design/methodology/approach – The paper is a literature-based conceptual analysis of the two philosophical movements, structuralism and post-structuralism, as represented by the seminal figures of Ferdinand de Saussure and Michel Foucault. Findings – The principles of ...

In many domains there are specific attributes in documents that carry more weight than the general words in the document. This paper proposes the use of information extraction techniques in order to identify these attributes for the domain of calls for papers. The utilisation of attributes into queries imposes new requirements on the retrieval method of conventional information retrieval system...
