Distributed Intelligent Agents
- IEEE Expert
, 1996
"... We are investigating techniques for developing distributed and adaptive collections of agents that coordinate to retrieve, filter and fuse information relevant to the user, task and situation, as well as anticipate a user's information needs. In our system of agents, information gathering is se ..."

Phrasal Translation and Query Expansion Techniques for Cross-Language Information Retrieval
- In Proceedings of the 20th International ACM SIGIR Conference on Research and Development in Information Retrieval
, 1997
"... Dictionary methods for cross-language information retrieval give performance below that for mono-lingual retrieval. Failure to translate multi-term phrases has been shown to be one of the factors responsible for the errors associated with dictionary methods. First, we study the importance of phrasal ..."

Increased availability of on-line text in languages other than English and increased multi-national collaboration have motivated research in cross-language information retrieval (CLIR) - the development of systems to perform
Applying Associative Retrieval Techniques to Alleviate the Sparsity Problem in Collaborative Filtering
- ACM Transactions on Information Systems
, 2004
"... this article, we propose to deal with this sparsity problem by applying an associative retrieval framework and related spreading activation algorithms to explore transitive associations among consumers through their past transactions and feedback. Such transitive associations are a valuable source o ..."

To evaluate the effectiveness of our approach, we have conducted an experimental study using a data set from an online bookstore. We experimented with three spreading activation algorithms including a
Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

1 Towards Collaborative Information Retrieval: Three Approaches
"... Abstract. The accuracy of ad-hoc document retrieval systems has plateaued in the last few years. At DFKI, we are working on so-called collaborative information retrieval (CIR) systems which unintrusively learn from their users ’ search processes. As a first step towards techniques, we focus on a res ..."

Collaborative Aspects of Information Retrieval Tools:
"... Information retrieval (IR) tools are engaged to find information in electronic form, in databases, digital libraries, and networks. However, the advent of the web technology has boosted the amount of information available to us way beyond our cognitive capacity. The importance of good IR tools has t ..."

User Oriented Information Retrieval in a Collaborative and Context Aware Search Engine
"... Abstract: The web is the largest knowledge system who people can access. Unfortunately, its size makes very complex to find the right information. Search engines help people but they face user with a large amount of results, mostly useless, and he have to select one by one the right satisfying needs ..."

To focus the attention on user requirements and involving the end-user in their systems, new search engines should evolve from keyword-based indexing and classification to more sophisticated techniques considering the meaning, the context and the usage of information. The key aspects are three
Learning about Potential Users of Collaborative Information Retrieval Systems

Reflective physical prototyping through integrated design, test, and analysis
- UIST '06. ACM
, 2006
"... Prototyping is the pivotal activity that structures innovation, collaboration, and creativity in design. Prototypes embody design hypotheses and enable designers to test them. Framing design as a thinking-by-doing activity foregrounds iteration as a central concern. This paper presents d.tools, a to ..."
