Meta Tags
Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes. The meta element has two uses: either to emulate the use of an HTTP response header field, or to embed additional metadata within the HTML document. With HTML up to and including HTML 4.01 and XHTML, there were four valid attributes: content, http-equiv, name and scheme. Under HTML 5, charset has been added and scheme has been removed. http-equiv is used to emulate an HTTP header, and name to embed metadata. The value of the statement, in either case, is contained in the content attribute, which is the only required attribute unless charset is given. charset is used to indicate the character set of the document ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

Meta
Meta (from the Greek μετά, '' meta'', meaning "after" or "beyond") is a prefix meaning "more comprehensive" or "transcending". In modern nomenclature, ''meta''- can also serve as a prefix meaning self-referential, as a field of study or endeavor (metatheory: theory about a theory, metamathematics: mathematical theories about mathematics, meta-axiomatics or meta-axiomaticity: axioms about axiomatic systems, metahumor: joking about the ways humor is expressed, etc.). Original Greek meaning In Greek, the prefix ''meta-'' is generally less esoteric than in English; Greek ''meta-'' is equivalent to the Latin words ''post-'' or ''ad-''. The use of the prefix in this sense occurs occasionally in scientific English terms derived from Greek. For example: the term ''Metatheria'' (the name for the clade of marsupial mammals) uses the prefix ''meta-'' in the sense that the ''Metatheria'' occur on the tree of life adjacent to the ''Theria'' (the placental mammals).

AltaVista
AltaVista was a Web search engine established in 1995. It became one of the most-used early search engines, but lost ground to Google and was purchased by Yahoo! in 2003, which retained the brand, but based all AltaVista searches on its own search engine. On July 8, 2013, the service was shut down by Yahoo!, and since then the domain has redirected to Yahoo!'s own search site. Etymology The word "AltaVista" is formed from the words for "high view" or "upper view" in Spanish (alta + vista); thus, it colloquially translates to "overview". Origins AltaVista was created by researchers at Digital Equipment Corporation's Network Systems Laboratory and Western Research Laboratory who were trying to provide services to make finding files on the public network easier. Paul Flaherty came up with the original idea, along with Louis Monier and Michael Burrows, who wrote the Web crawler and indexer, respectively. The name "AltaVista" was chosen in relation to the surroundings of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DMOZ
DMOZ (from ''directory.mozilla.org'', an earlier domain name, stylized in lowercase in its logo) was a multilingual open-content directory of World Wide Web links. The site and community who maintained it were also known as the Open Directory Project (ODP). It was owned by AOL (now a part of Verizon Media) but constructed and maintained by a community of volunteer editors. DMOZ used a hierarchical ontology scheme for organizing site listings. Listings on a similar topic were grouped into categories which then included smaller categories. DMOZ closed on March 17, 2017 because AOL no longer wished to support the project. The website became a single landing page on that day, with links to a static archive of DMOZ, and to the DMOZ discussion forum, where plans to rebrand and relaunch the directory are being discussed. , a non-editable mirror remained available at dmoztools.net, and it was announced that while the DMOZ URL would not return, a successor version of the directory na ...

Live Search
Microsoft Bing (commonly known as Bing) is a web search engine owned and operated by Microsoft. The service has its origins in Microsoft's previous search engines: MSN Search, Windows Live Search and later Live Search. Bing provides a variety of search services, including web, video, image and map search products. It is developed using ASP.NET. Bing, Microsoft's replacement for Live Search, was unveiled by Microsoft CEO Steve Ballmer on May 28, 2009, at the '' All Things Digital'' conference in San Diego, California, for release on June 3, 2009. Notable new features at the time included the listing of search suggestions while queries are entered and a list of related searches (called "Explore pane") based on semantic technology from Powerset, which Microsoft had acquired in 2008. In July 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo! Search. Yahoo! finished the transition in 2012. In October 2011, Microsoft stated that they were working on new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Crawler
A Web crawler, sometimes called a spider or spiderbot and often shortened to crawler, is an Internet bot that systematically browses the World Wide Web and that is typically operated by search engines for the purpose of Web indexing (''web spidering''). Web search engines and some other websites use Web crawling or spidering software to update their web content or indices of other sites' web content. Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. Crawlers consume resources on visited systems and often visit sites unprompted. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent. For example, including a robots.txt file can request bots to index only parts of a website, or nothing at all. The number of Internet pages is extremely large; ev ...

Search Engine Indexing
Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science. An alternate name for the process, in the context of search engines designed to find web pages on the Internet, is ''web indexing''. Popular engines focus on the full-text indexing of online, natural language documents. Media types such as pictures, video, audio, and graphics are also searchable. Meta search engines reuse the indices of other services and do not store a local index whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent-based search engines ind ...

IETF Language Tag
An IETF BCP 47 language tag is a standardized code or tag that is used to identify human languages in the Internet. The tag structure has been standardized by the Internet Engineering Task Force (IETF) in ''Best Current Practice (BCP) 47''; the subtags are maintained by the ''IANA Language Subtag Registry''. To distinguish language variants for countries, regions, or writing systems (scripts), IETF language tags combine subtags from other standards such as ISO 639, ISO 15924, ISO 3166-1 and UN M.49. For example, the tag "en" stands for English; "es-419" for Latin American Spanish; "rm-sursilv" for Romansh Sursilvan; "sr-Cyrl" for Serbian written in Cyrillic script; "nan-Hant-TW" for Min Nan Chinese using traditional Han characters, as spoken in Taiwan; and "gsw-u-sd-chzh" for Zürich German. In its accordance with ISO 639-3, however, it does not provide codes for distinguishing between Arabic-based scripts, and maintains two duplicate codes for Punjabi, as well as a numb ...

Search Engine Results Page
Search Engine Results Pages (SERP) are the pages displayed by search engines in response to a query by a user. The main component of the SERP is the listing of results that are returned by the search engine in response to a keyword query. The page that a search engine returns after a user submits a search query. In addition to organic search results, search engine results pages (SERPs) usually include paid search and pay-per-click (PPC) ads. The results are of two general types : * organic search: retrieved by the search engine's algorithm * sponsored search: advertisements. The results are normally ranked by relevance to the query. Each result displayed on the SERP normally includes a title, a link that points to the actual page on the Web, and a short description showing where the keywords have matched content within the page for organic results. For sponsored results, the advertiser chooses what to display. Due to the huge number of items that are available or related to ...

Favicon
A favicon (; short for favorite icon), also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons, associated with a particular website or web page. A web designer can create such an icon and upload it to a website (or web page) by several means, and graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar (sometimes in the history as well) and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab, and site-specific browsers use the favicon as a desktop icon. History In March 1999, Microsoft released Internet Explorer 5, which supported favicons for the first time. Originally, the favicon was a file called favicon.ico placed in the root directory of a website. It was used in Internet Explorer's ''favorites'' ...
