Exploratory search is an increasingly important activity yet challenging for users. Although there exists an ample amount of research into understanding exploration, most of the major information retrieval (IR) systems do not provide tailored and adaptive support for such tasks. One reason is the lack of empirical knowledge on how to distinguish exploratory and lookup search behaviors in IR sys...

Many real life search tasks are complex, multi-stepped processes. As people explore a search space, they want to find the most relevant information available to them while remaining oriented in the space they have already explored. This paper argues that during exploration it is important for search engines to present relevant information to their users in a way that maintains the users’ existi...

Recently, exploratory search has received much attention in information retrieval and database fields. This search paradigm assists users who do not have a clear search intent and are unfamiliar with the underlying data space. Specifically, query formulation evolves iteratively as the user becomes more familiar with the content. Despite its growing importance, exploratory search on graph-struct...

Abstract Exploratory search starts with ill-defined goals and involves browsing, learning, formulating new targets for search. To fluidly support such dynamic behaviours, we focus on devising interactive visual facets (IVF) , visualising information to user comprehension control of the space. We reviewed existing faceted interfaces derived two design requirements (DR) that have not been fully a...

Linked datasets now constitute a valuable background knowledge for supporting exploration and discovery objectives through browsers, recommenders and exploratory search systems in particular. Today there is a need to look at the achievements and tendencies in this rapidly developing field in order to better orient the future research works. In this paper we propose a survey of such systems from...

Abstract: This study examines how the governance form of an alliance enables partners to develop, transfer and protect knowledge in alliances. More integrative forms of control are expected when collaborations are exploratory in nature, when partners are moderately similar in technological knowledge and when industry rivalry increases. An empirical analysis of alliances, patent cross-citation r...

New search modes have been introduced recently in SOWIPORT to support the exploratory search on the basis of automatically linked references and citations. References are therefore linked to the complete data corpus via specific matching procedures. With this approach we have done a major step towards a navigable citation index in the field of the German social sciences.
