“…However, apart from Google that use link structures among Web pages for ranking, enhanced network models of science have not been widely used in scholarly information systems so far. Our model of author centrality based ranking originates from the model initially proposed by Mutschke (1994) which has been re-implemented for a real-life IR environment, to our knowledge before anyone else, within the Daffodil system (Mutschke 2001;Fuhr et al 2002).…”

Models of science address statistical properties and mechanisms of science. From the perspective of scholarly information retrieval (IR) science models may provide some potential to improve retrieval quality when operationalized as specific search strategies or used for rankings. From the science modeling perspective, on the other hand, scholarly IR can play the role of a validation model of science models. The paper studies the applicability and usefulness of two particular science models for re-ranking search results (Bradfordizing and author centrality). The paper provides a preliminary evaluation study that demonstrates the benefits of using science model driven ranking techniques, but also how different the quality of search results can be if different conceptualizations of science are used for ranking.

In this demo, we present Proteus, a novel interface for interacting with multiple retrieval types extracted from scanned books provided by the Internet Archive. The primary purpose of Proteus is to provide a rich interactive experience for users to explore collections with automatically extracted and linked entity data. The system supports seamlessly shifting perspectives between books, entities, and topics. Proteus provides a starting point for a variety of exploratory search tasks.

Abstract. In the paper we present the organization of the INEX 2009 interactive track. For the 2009 experiments the iTrack has gathered data on user search behavior in a collection consisting of book metadata taken from the online bookstore Amazon and the social cataloguing application LibraryThing. Thus the data are more structured than in previous years' experiments, consisting of traditional bibliographic metadata, user-generated tags and reviews and promotional texts and reviews from publishers and professional reviewers. Through monitoring searches based on three different task types the experiment aims at studying how users interact with highly structured data. We describe the methods used for data collection and the tasks performed by the participants. Some preliminary results of the interaction analysis are reported.
