Most Information Retrieval models offer only limited support to searchers who possess only a vague and inexpressible understanding of their actual information need. A search process that begins with this inexplicit understanding is referred to as exploratory searching. This research aims to improve the current state of research surrounding exploratory searching, by providing the searcher with a...

Success in Question Answering has been traditionally measured by precision and recall, which are good metrics for identifying specific best answer(s) that might be obtained by a lookup type of search. These metrics do not address the many information gathering techniques in exploratory interactions. In this paper, we present an integrated Question Answering environment that combines a visual an...

Information Retrieval (IR) research has recently started addressing the information need of exploratory search. where the searcher may be unfamiliar with the domain or not have decided what is the goal of his query. A popular tool to support exploratory search is the use of faceted search. The implementation of faceted search requires that documents be annotated by metadata in the form of attri...
