In this paper, a set of new Real-Coded Genetic Algorithms (RCGAs) with local and global exploratory search capabilities are proposed. The search capabilities are based on the inclusion of a modified crossover procedure and a new global exploratory method in RCGA. The global exploratory method is based on vector projection while the modified crossover procedure is based on a limited version of t...

Exploratory search over a collection often requires users to iteratively apply a variety of strategies, such as searching for more general or more specific concepts in reaction to the information they encounter. Rich semantic models, such as WordNet, are potentially valuable aids for making sense of this information. However, these large complex models often contain specialized vocabularies and...

Subjectivity is inherent in exploratory search. It is evident in the attributes of the searcher before beginning the search (e.g., the searcher’s domain knowledge). In the form of the searcher’s interests, knowledge, cognitive/learning style, and personality, it affects the search process – its overall trajectory. And it comes into play at the end of the search, when the searcher makes judgment...

We report on the construction of a new query log corpus that consists of 150 exploratory search missions, each of which corresponds to one of the topics used at the TREC Web Tracks 2009–2011. Involved in the construction was a group of 12 professional writers, hired at the crowdsourcing platform oDesk, who were given the task to write essays of 5000 words length about these topics, thereby indu...

At present, the promise of the Semantic Web has yet to be realized, partly because there are few real-world applications that allow end-users to access, view and process Semantic Web information. We aim to facilitate Semantic Web adoption by providing users with advanced exploratory search capability over Semantic Web data by providing a faceted exploratory search interface for arbitrary Semant...

Linked Data offers an entity-based infrastructure to resolve indirect relations between resources, expressed as chains of links. If we could benchmark how effective retrieving chains of links from these sources is, we can motivate why they are a reliable addition for exploratory search interfaces. A vast number of applications could reap the benefits from encouraging insights in this field. Esp...

In this paper we present LocLinkVis (Locate-Link-Visualize); a system which supports exploratory information access to a document collection based on geo-referencing and visualization. It uses a gazetteer which contains representations of places ranging from countries to buildings, and that is used to recognize toponyms, disambiguate them into places, and to visualize the resulting spatial foot...

The Semantic Web contains well organized information in structured form, what gives opportunity for more effective automated information processing. But its data structure is not directly readable for common users. This with combination of exponentially grooving amount of information on the Web escalates to necessary of additional support for common users to find desired information in informat...

To date, children come more and more often into contact with information systems. Unfortunately, these systems are usually designed for adults and the increasing group of young users has been widely neglected. In order to create and support children’s information seeking appropriately, we have to consider their specific state of development resulting into different needs and capabilities. In th...

This paper presents an optimal design of linear phase digital low pass finite impulse response (FIR) filter using hybrid particle swarm optimization (HPSO) technique where PSO has been hybridized with exploratory search technique. PSO is a simple, population based robust global search algorithm capable of handling large search space. Exploratory move is a gradient free deterministic algorithm, ...
