1Tenopir, C. ; Wang, P. ; Zhang, Y. ; Simmons, B. ; Pollard, R.: Academic users' interactions with ScienceDirect in search tasks : affective and cognitive behaviors.
In: Information processing and management. 44(2008) no.1, S.105-121.
Abstract: This article presents part of phase 2 of a research project funded by the NSF-National Science Digital Library Project, which observed how academic users interact with the ScienceDirect information retrieval system for simulated class-related assignments. The ultimate goal of the project is twofold: (1) to find ways to improve science and engineering students' use of science e-journal systems; (2) to develop methods to measure user interaction behaviors. Process-tracing technique recorded participants' processes and interaction behaviors that are measurable; think-aloud protocol captured participants' affective and cognitive verbalizations; pre- and post-search questionnaires solicited demographic information, prior experience with the system, and comments. We explored possible relationships between affective feelings and cognitive behaviors. During search interactions both feelings and thoughts occurred frequently. Positive feelings were more common and were associated more often with thoughts about results. Negative feelings were associated more often with thoughts related to the system, search strategy, and task. Learning styles are also examined as a factor influencing behavior. Engineering graduate students with an assimilating learning style searched longer and paused less than those with a converging learning style. Further exploration of learning styles is suggested.

2Eijk, C.C. van der ; Mulligen, E.M. van ; Kors, J.A. ; Mons, B. ; Berg, J. van den: Constructing an associative concept space for literature-based discovery.
In: Journal of the American Society for Information Science and technology. 55(2004) no.5, S.436-444.
Abstract: Scientific literature is often fragmented, which implies that certain scientific questions can only be answered by combining information from various articles. In this paper, a new algorithm is proposed for finding associations between related concepts present in literature. To this end, concepts are mapped to a multidimensional space by a Hebbian type of learning algorithm using co-occurrence data as input. The resulting concept space allows exploration of the neighborhood of a concept and finding potentially novel relationships between concepts. The obtained information retrieval system is useful for finding literature supporting hypotheses and for discovering previously unknown relationships between concepts. Tests an artificial data show the potential of the proposed methodology. In addition, preliminary tests an a set of Medline abstracts yield promising results.

Abstract: In response to the ever increasing complexity of international scientific networking, the Dutch Govemment through NWO, The Netherlands Organization for Scientific Research, has taken the initiative to develop a global information system for Research Councils with the working title IRIS (International Research Information System). Most Research Councils consider finding referees a frustrating and time-consuming process. Too often major resources are spent an maintaining websites, indexing research proposals, trying to find the perfect referee, and evaluating researchers and research institutes. Science Managers should ideally have access to information about referees from any country or discipline in the most effective way possible. This paper describes the pilot phase of the IRIS project, aimed at the construction and set up of an International System to share reviewers.
