The research field Exploratory search, embedded in the field of Human Computer Interaction (HCI), aims for a next generation of search interfaces beyond the document centered Google-like approaches. New interfaces should support users to find information even if their goal is vague, to learn from the information, and to investigate solutions for complex information problems. The goal of this th...
This paper reports on a study investigating the information seeking and sensemaking processes undertaken by groups engaged in collaborative exploratory searches. We conducted semi-structured interviews with eight participants who each described two collaborative search experiences: one with friends or family who they knew well, and one with a project group for school or work. Our results highli...
This paper consists of design of digital FIR high pass filter using predator prey optimization and hybrid predator prey optimization (HPPO) technique. HPPO is a combination of predator prey optimization (PPO) and exploratory search where Predator prey optimization is a global search method and exploratory move is a local search method. Local stagnation is possible in PSO but there is no local s...
Search algorithms in image retrieval tend to focus on giving the user more and more similar images based on queries that the user has to explicitly formulate. Implicitly, such systems limit the users exploration of the image space and thus remove the potential for serendipity. As a response, in recent years there has been an increased interest in developing content based image retrieval systems...
A traditional relational database can evaluate complex queries but requires users to precisely express their information need. But users often do not know what information is available in a database, and hence cannot correctly express their information need. Traditional databases do not provide convenient means for users to gain familiarity with the data. In this paper, we study the problem of ...
Today’s search engines provide instant keyword-based auto-suggestion and completion of the user’s search queries. This paper presents a novel auto-suggestion interface for the Semantic Multimedia Explorer (SEMEX), a semantic search engine that supports entity-based exploratory video retrieval. In difference to traditional textbased retrieval, auto-suggestion and auto-completion of the user’s qu...
In this work dual-process theory from the social psychology domain is introduced to help understand exploratory search behaviors and relate them to searchers’ cognitive processes as they evaluate information resources. Our setting is the consumer health domain, where information seeking is often an exploratory search episode involving searchers who have high motivation but low ability to find a...
When people search for information about a new topic within large document collections, they implicitly construct mental model of the unfamiliar space to represent what currently know and guide their exploration into unknown. Building this can be challenging as it requires not only finding relevant documents but also synthesizing important concepts relationships that connect those both across d...
In this paper, we explore various search tasks that are supported by a social bookmarking service. These bookmarking services hold great potential to powerfully combine personal tagging of information sources with interactive browsing, resulting in better social navigation. While there has been considerable interest in social tagging systems in recent years, little is known about their actual u...
Recently, there has been a great deal of interest in how new technologies can support the more effective use of online museum content. Two particularly relevant developments are exploratory search and semantic web technologies. Exploratory search tools support a more undirected and serendipitous interaction with the content. Semantic web technology, when applied in this context, allows the expl...
