Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that can't be indexed and searched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouseover
In computing, a mouseover, or hover box is a graphical control element that is activated when the user moves or hovers the pointer over a trigger area, usually with a mouse, but also possible with a digital pen. Mouseover control elements are common in web browsers. For example, hovering over a hyperlink triggers the mouseover control element to display a URL on the status bar. Site designers can define their own mouseover events using JavaScript or Cascading Style Sheets. Mouseover events are frequently used in web design and graphical user interface programming. It is also known as rollover, which refers to a button created by a web developer or web designer, found within a web page, used to provide interactivity between the user and the page itself. The term rollover in this regard originates from the visual process of "rolling the mouse cursor over the button" causing the button to react (usually visually, by replacing the button's source image with another image), and so ...

Toolbar
The toolbar, also called a bar or standard toolbar (originally known as ribbon) is a graphical control element on which on-screen icons can be used. A toolbar often allows for quick access to functions that are commonly used in the program. Some examples of functions a toolbar might have are open file, save, and change font. Toolbars are usually distinguished from palettes by their integration into the edges of the screen or of other windows. This can result in wasted space if multiple underpopulated bars are stacked atop each other or interface inefficiency if overloaded bars are placed on small windows. Variants There are several user interface elements derived from toolbars: * An address bar, location bar or URL bar is a toolbar that mainly consists of a text box. It typically accepts URLs or file system addresses. They are found in web browsers and file managers. * A breadcrumb or breadcrumb trail allows users to keep track of their locations within a program or a file sys ...

Open Access (publishing)
Open access (OA) is a set of principles and a range of practices through which research outputs are distributed online, free of access charges or other barriers. With open access strictly defined (according to the 2001 definition), or libre open access, barriers to copying or reuse are also reduced or removed by applying an open license for copyright. The main focus of the open access movement is "peer reviewed research literature". Historically, this has centered mainly on print-based academic journals. Whereas non-open access journals cover publishing costs through access tolls such as subscriptions, site licenses or pay-per-view charges, open-access journals are characterised by funding models which do not require the reader to pay to read the journal's contents, relying instead on author fees or on public funding, subsidies and sponsorships. Open access can be applied to all forms of published research output, including peer-reviewed and non peer-reviewed academic journal ...

Hybrid Open Access Journal
A hybrid open-access journal is a subscription journal in which some of the articles are open access. This status typically requires the payment of a publication fee (also called an article processing charge or APC) to the publisher in order to publish an article open access, in addition to the continued payment of subscriptions to access all other content. Strictly speaking, the term "hybrid open-access journal" is incorrect, possibly misleading, as using the same logic such journals could also be called "hybrid subscription journals". Simply using the term "hybrid access journal" is accurate. Publishers that offer a hybrid open access option often use different names for it. The SHERPA/RoMEO site provides a list of publishers and the names of their options. The Open Access Directory provides a list of funds that support open access journals, and provides information about which funds will pay fees of hybrid open access journals. Origins The concept was first proposed in 1998 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Scholar
Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents. Google Scholar uses a web crawler, or web robot, to identify files for inclusion in the search results. For content to be indexed in Google Scholar, it must meet certain specified criteria. An earlier statistical estimate published in PLOS One using a mark and recapture method estimated approximately 80–90% coverage of all articles published in English with an estimate of 100 million.''Trend Watch'' (2014) Nature 509(7501), 405 – discussing Madian Khabsa and C Lee Giles (2014''The Number of Scholarly Documents on the Public Web'' ...

Windows Live Academic
Live Search Academic was a Web search engine for scholarly literature that existed from April 2006 to May 2008; it was part of Microsoft's Live Search group of services. It was similar to Google Scholar, but rather than crawling the Internet for academic content, search results came directly from trusted sources, such as publishers of academic journals. Users were required to log in to access the service. Live Search Academic was known as Windows Live Academic Search when the beta version was officially launched on April 11, 2006. The name had changed to Live Search Academic by December 6, 2006, when Microsoft announced the addition of millions of new articles, mainly in biomedicine. On May 23, 2008, Microsoft announced the end of Live Search Academic and Live Search Books, both sites to be closed, with their results integrated into regular Search. The project scanned 750,000 books and indexed 80 million journal articles. Features Live Search Academic indexed journal articles, ...

BASE (search Engine)
BASE (Bielefeld Academic Search Engine) is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. It is based on free and open-source software such as Apache Solr and VuFind. It harvests OAI metadata from institutional repositories and other academic digital libraries that implement the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and then normalizes and indexes the data for searching. In addition to OAI metadata, the library indexes selected web sites and local data collections, all of which can be searched via a single search interface. Functionality Users can search bibliographic metadata including abstracts, if available. However, BASE does not currently offer full text search. It contrasts with commercial search engines in multiple ways, including in the types and kinds of resources it searches and the information it offers about the results it finds. Results can be narrowed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PubMed
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintain the database as part of the Entrez system of information retrieval. From 1971 to 1997, online access to the MEDLINE database had been primarily through institutional facilities, such as university libraries. PubMed, first released in January 1996, ushered in the era of private, free, home- and office-based MEDLINE searching. The PubMed system was offered free to the public starting in June 1997. Content In addition to MEDLINE, PubMed provides access to: * older references from the print version of ''Index Medicus'', back to 1951 and earlier * references to some journals before they were indexed in Index Medicus and MEDLINE, for instance ''Science'', ''BMJ'', and ''Annals of Surgery'' * very recent entries to records for an article before it ...
