Prospective Search
Prospective search, or persistent search, is a method of searching which determines which of a set of queries matches content in a corpus. Other names include document routing and percolate queries. It is sometimes called reverse search, but that can also refer to finding documents similar to a given document. This differs from traditional, or "retrospective", search such as search engines, where the information for the results is acquired and then queried. Comparison to retrospective search Ordinary search, also called retrospective search, starts by gathering information, indexing it, then letting users query it. A query produces results if the information is in the corpus at the time the query is issued. In contrast, prospective search starts with the user's queries, gathers the information in a targeted way, indexes it, and then provides results as they arrive. That is, a query produces results when new information that matches it is added to the corpus. Sometimes Ping Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engine Technology
A search engine is an information retrieval software program that discovers, crawls, transforms and stores information for retrieval and presentation in response to user queries. A search engine normally consists of four components, that are search interface, crawler (also known as a spider or bot), indexer, and database. The crawler traverses a document collection, deconstructs document text, and assigns surrogates for storage in the search engine index. Online search engines store images, link data and metadata for the document as well. History of Search Technology The Memex The concept of hypertext and a memory extension originates from an article that was published in The Atlantic Monthly in July 1945 written by Vannevar Bush, titled As We May Think. Within this article Vannevar urged scientists to work together to help build a body of knowledge for all mankind. He then proposed the idea of a virtually limitless, fast, reliable, extensible, associative memory storage and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engines
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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ping Blog
In blogging, a ping is an XML-RPC-based push mechanism by which a weblog notifies a server that its content has been updated. An XML-RPC signal is sent from the weblog to one or more Ping servers, as specified by originating weblog), to notify a list of their "Services" of new content on the weblog. A Ping Server may notify multiple services when pinged; * Search engines * Website directories * News websites * Aggregators * Feed websites History Server adoption The technology was first introduced by Dave Winer to Weblogs.com in October 2001. The site was powered by receiving pings from individual blog and podcast websites using weblogUpdates.ping() calls over the XML-RPC protocol. The server protocol was later adopted by FeedBurner's Pingshot, Automattic's Ping-O-Matic, Google Blogsearch, Källström's Twingly, and others. Open ping servers, like Moreover Technologies' Weblogs.com, let other web services subscribe to a list of blogs that have recently pinged them. Blog ...

Blog
A blog (a truncation of "weblog") is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (posts). Posts are typically displayed in reverse chronological order so that the most recent post appears first, at the top of the web page. Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic. In the 2010s, "multi-author blogs" (MABs) emerged, featuring the writing of multiple authors and sometimes professionally edited. MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media. ''Blog'' can also be used as a verb, meaning ''to maintain or add content to a blog''. The emergence and growth of blogs i ...

Google Alerts
Google Alerts is a content change detection and notification service, offered by Google. The service sends emails to the user when it finds new results—such as web pages, newspaper articles, blogs, or scientific research—that match the user's search term(s). In 2003, Google launched Google Alerts, which were the result of Naga Kataru's efforts. His name is on the three patents for Google Alerts. Google reported the system was not functioning properly as of 2013: "we're having some issues with Alerts not being as comprehensive as we'd like". However, the service is still operational and completely accessible around the world.

Selective Dissemination Of Information
Selective dissemination of information ("SDI") was originally a phrase related to library and information science. SDI refers to tools and resources used to keep a user informed of new resources on specified topics, including the current-awareness services used to inform about new library acquisitions.{{cite web, url=https://www.britannica.com/topic/library/User-services#ref62059, title=Library: User services, author=Britannica SDI services pre-date the World Wide Web, and the term itself is somewhat dated. Contemporary analogous systems for SDI services include alerts, current awareness tools or trackers. These systems provide automated searches that inform the user of the availability of new resources meeting the user's specified keywords and search parameters. Alerts can be received a number of ways, including email, RSS feeds, voice mail, Instant messaging, and text messaging. Selective dissemination of information was a concept first described by Hans Peter Luhn of IBM in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superfeedr
Superfeedr is a feed API built on WebSub, which is sometimes referred to as PuSH. It transforms a variety of feeds into standardized RSS, Atom, or JSON format and distributes (or "pushes") them via WebSub or XMPP. This allows subscribers to receive new notifications or updated content from their feeds and publishers to send those notifications. History Superfeedr was launched by in 2009 by parent company Notifixious. While Notifixious' website went offline sometime between September 23, 2009 January 5, 2010, Superfeedr has remained online and available. While the website of Notifixious, the parent company of Superfeedr, is no longer available Superfeedr continues to refer to it in the terms of service for the site. Superfeedr was bought by Medium in 2016. Technology PuSH is a protocol that relies on webhooks to push feed updates in real-time from publishers to subscribers in a decentralized manner. PuSH builds on existing protocols, ensuring that polling infrastructures currentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
