State-of-the-art faceted search graphical user interfaces for digital libraries provide a wide range of filters perfectly suitable for narrowing down results for well-defined user needs. However, they fail to deliver summarized overview information for users that need to familiarize themselves with a new scientific topic. In fact, exploratory search remains one of the major problems for scienti...

We use information retrieval (IR) systems to meet a broad range of information needs, from simple ones involving day-to-day decisions to complex and imprecise information needs that cannot be easily formulated as a question. In consideration of these diverse goals, search activities are commonly divided into two broad categories: lookup and exploratory. Lookup searches begin with precise search...

Current image retrieval systems ooer either an exploratory search method through browsing and navigation or a direct search method based on speciic queries. Combining both of these methods in a uniform framework allows users to formulate queries more naturally, since they are already acquainted with the contents of the database and with the notion of matching the machine would use to return res...

There are growing arguments that linked data technologies can be utilised to enable user-oriented exploratory search systems for the future Internet. Recently, search over linked data has been studied in different domains and contexts. However, there is still limited insight into how conventional semantic browsers over linked data can be extended to empower exploratory search, which is open-end...

In order to provide a qualitative support to the users during a web search, it is important to have access to a multitude of information sources simultaneously. Depending on the available domain expertise, the user can get an overview and insight to different information perspectives and compare the quality of resources. In this work, we present an exploratory search engine that simultaneously ...

The first generation of search tools provided remarkable capabilities to many researchers for finding specific information, navigating to desired websites or tracking down needed documents. A second generation of tools is helping researchers conduct exploratory search in situations where the goals are less clear, where complete coverage is necessary, and where proof of absence is required (pate...

The aim of this tutorial is first to provide in-depth explanations of DOREMUS, a model for describing music metadata. We will demonstrate how real data coming frommusical libraries can be converted to this model by presenting the whole DOREMUS tools chain. We will illustrate how the DOREMUS data can be used for query answering and consumed through various applications including an exploratory s...

Kothari, Sarika S. M.S., Purdue University, May, 2010. Evaluating the Efficacy of Clustered Visualization in Exploratory Search Tasks. Major Professor: James Mohler. Information visualization has the potential to improve the quality of Web search results representation providing more context and novel ways to see relationships among items in a result set. The key objective of this research was ...

Modern information seekers face dynamic streams of large-scale heterogeneous data that is both intimidating and overwhelming. They need a strategy to filter this barrage of massive data sets, and to find all of the information responding to their information needs, despite the pressures imposed by schedules and budgets. In this applied research, we present an exploratory search strategy that al...
