Web Search is increasingly entity-centric; as many common queries target specific entities, search results are progressively augmented with semi-structured and multimedia information about entities. However, search over personal Web browsing history still revolves around keyword-search mostly. B-hist aims at providing Web users with an effective tool for searching and accessing information prev...

The evolution of the Internet topology has never been subject to a long-term quantitative analysis, despite the potential importance of the analysis’ results. This paper surveys the current state of the art in all of the fields required, and finds that the time is ripe for exactly such a study to be performed. We close with a proposed timeline for completing this study, a brief description of w...

We propose a simple web search engine based method for collecting approximated historical data of temporally changing social adaptive networks, which are rather difficult to obtain experimentally in conventional research methods. In the proposed method, a search query string is combined with additional keywords that specify inclusion/exclusion of specific years to limit the search results to a ...

MOTIVATION Visualizing search histories and supplying the user with interaction methods such as zooming, brushing and linking, annotation and tagging, has attracted increasing attention in scientific literature (Liu, Hong, & Pedersen, 2010), (Pedersen, Gyllstrom, Gu, & Hong, 2010), (Cernea, Truderung, Kerren, & Ebert, 2013), and (Yu & Ingalls, 2011). The overall assumption is that the user’s in...

The success of sponsored search has radically affected how people interact with the information, websites, and services on the web. Sponsored search provides the necessary revenue streams to web search engines and is critical to the success of many online businesses. However, there has been limited academic examination of sponsored search, with the exception of online auctions. In this paper, w...

Users are depending on the web to pursue complex tasks and to achieve broader information. Search of complex tasks usually breaks down into co-dependent steps and issue multiple queries. Query Grouping is used to collect related queries which need common information. Query groups are used to support user in their long term information search. Online query groups are created in an automated and ...

Background: Understanding the physiological and psycho-social effects of pregnancy through Assisted Reproductive Technologies (ARTs) will enable health care providers to identify and treat any adverse outcomes, and provide support to women seeking fertility treatments. The aim of this paper was to review studies describing prenatal care in pregnancy through ARTs. Methods: A systematic search o...

Using a gaze-contingent paradigm, we directly measured observers' memory capacity for fixated distractor locations during search. After approximately half of the search objects had been fixated, they were masked and a spatial probe appeared at either a previously fixated location or a non-fixated location; observers then rated their confidence that the target had appeared at the probed location...

The Reactive Search (RS) method proposes the integration of a simple history-based feedback scheme into local search for the on-line determination of free parameters. In this paper a new RS algorithm is proposed for the approximated solution of the Maximum Satissability problem: a component based on local search with temporary prohibitions is complemented with a reactive scheme that determines ...

This project assesses the resources necessary to make oral history searchable by means of automatic speech recognition (ASR). There are many inherent challenges in applying ASR to conversational speech: smaller training set sizes and varying demographics, among others. We assess the impact of dataset size, word error rate and term-weighted value on human search capability through an information...
