The survey of the CIKM Call for Papers for the period 1998 - 2002 demonstrates that the CIKM organizers very accurately "identify challenging problems facing the development of future knowledge and information systems [in] applied and theoretical research" [1998] and also play an important role fostering "bridging traditionally separated areas ...

In October 1991 the National Science Foundation (NSF) sponsored a workshop to examine the role of the Information Retrieval research community in the emerging environment of Internet, high performance text processing capabilities and ever-increasing volumes of digitized documents. Ed Fox, Michael Lesk and Michael McGill drafted a White Paper, calling ...

To address the challenge of adapting Information Retrieval (IR) to the constantly evolving user tasks and needs and to adjust it to user interactions and preferences we develop a new model of user behavior based on Markov chains. We aim at integrating the proposed model into several aspects of IR, ...

Progress and innovation are driven by experiments, but experimentation is useless without an objective evaluation measure that allow researchers to detect the improvements and identify the successful strategies. Due to the experimental nature of Information Retrieval (IR), accurately interpreting the result of a system in terms of user satisfaction is ...

Narrowing down the context in the ranking phase of information retrieval has been shown to produce results that are more relevant to searcher's need. We have identified two types of contexts that could be used in the process of personalisation. We research these contexts in the domain of personalised search, ...

Many important applications in scientific fields such as Bioinformatics depend on the management of large collections of heterogeneous XML documents, containing complex domain-specific data. To allow advanced querying, these systems need to support techniques such as data exploration and approximate query processing by using multiple notions of similarity. The development ...

Our work focuses on the improvement of the accuracy of context-aware recommender systems. Contextual information showed to be promising factor in recommender systems. However, pure context-based recommender systems can not outperform other approaches mainly due to high sparsity of contextual information. We propose an idea to improve accuracy of context ...

Ontologies play an important role in the Semantic Web. Currently, several Web ontology languages have been proposed and there has been a substantial effort towards the formalization of different knowledge domains. However, it is difficult to identify the ontologies for a specific domain and their annotated Web sources.XWebSOGO is a ...

Students' performance in Massive Open Online Courses (MOOCs) is enhanced by high quality discussion forums or recently emerging educational Community Question Answering (CQA) systems. Nevertheless, only a small number of students answer questions asked by their peers. This results in instructor overload, and many unanswered questions. To increase students' participation, ...

Hash-based similarity search reduces a continuous similarity relation to the binary concept "similar or not similar": two feature vectors are considered as similar if they are mapped on the same hash key. From its runtime performance this principle is unequaled--while being unaffected by dimensionality concerns at the same time. Similarity ...

Heterogeneity arises naturally in virtually all real-world data. This paper presents evolutionary extensions to a relational database system for supporting three classes of data heterogeneity: variational, structural and annotational heterogeneities. We define these classes and show the impact of these new features on data storage, data-access mechanisms, and the data-description ...

In this paper we examine recent work in the area of spatial clustering with obstacles [14, 13] and present a discussion of several identified drawbacks. We propose an algorithm, called GRAVIclust, which addresses the identified problems. The algorithm uses a heuristic to pick the initial cluster centres and utilises centre ...
