Martin Porter
Martin F. Porter is the inventor of the Porter Stemmer, one of the most common algorithms for stemming English, and the Snowball programming framework. His 1980 paper "An algorithm for suffix stripping", proposing the stemming algorithm, has been cited over 8000 times (Google Scholar). The Muscat search engine comes from research performed by Porter at the University of Cambridge and was commercialized in 1984 by Cambridge CD Publishing; it was subsequently sold to MAID which became the Dialog Corporation. Part of Dialog was then spun off to become BrightStation in 2000, which transitioned Open Muscat to a closed-source development model in 2001. Subsequently, a group of developers led by Porter initiated a project based on Open Muscat called Xapian and released the first official version on September 30, 2002. In 2000 he was awarded the Tony Kent Strix award. Porter read mathematics at St John's College, Cambridge (1963–66) and went to get a Diploma in Computer Science (1967 ...

Inventor
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stemming
In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. Algorithms for stemming have been studied in computer science since the 1960s. Many search engines treat words with the same stem as synonyms as a kind of query expansion, a process called conflation. A computer program or subroutine that stems word may be called a ''stemming program'', ''stemming algorithm'', or ''stemmer''. Examples A stemmer for English operating on the stem ''cat'' should identify such strings as ''cats'', ''catlike'', and ''catty''. A stemming algorithm might also reduce the words ''fishing'', ''fished'', and ''fisher'' to the stem ''fish''. The stem need not be a word, for examp ...

Dialog (online Database)
Dialog is an online information service owned by ProQuest, who acquired it from Thomson Reuters in mid-2008. Dialog was one of the predecessors of the World Wide Web as a provider of information, though not in form. The earliest form of the Dialog system was completed in 1966 in Lockheed Martin under the direction of Roger K. Summit. According to its literature, it was "the world's first online information retrieval system to be used globally with materially significant databases". In the 1980s, a low-priced dial-up version of a subset of Dialog was marketed to individual users as ''Knowledge Index''.Phyllis E. WordenKnowledge Index ''Journal of Extension'', Volume 26 Number 2, 1988. ISSN 1077-5315 This subset included INSPEC, MathSciNet, over 200 other bibliographic and reference databases, as well as third-party retrieval vendors who would go to physical libraries to copy materials for a fee and send it to the service subscriber.

Dan Wagner
Daniel Maurice Wagner (born 28 July 1963) is a British Internet entrepreneur. He created MAID, one of the first online information platforms in 1984. He was later the founder and CEO of Venda, ATTRAQT, Powa Technologies and most recently, Rezolve. Early life Wagner was born in Edgware, Middlesex on 28 July 1963. He was educated at Merchant Taylors' School, Northwood but expelled when he was 13, before attending several schools, ending up at University College School, London. Wagner dropped out of school when he was sixteen years old to work as a shop assistant for entrepreneur Julian Richer at Richer Sounds. Afterwards he joined an advertising agency as an account executive. There he came up with the idea of creating databases of records about businesses as a resource for marketing professionals. Career MAID/Dialog After Wagner left his job at the advertising agency, he founded the online information company MAID (''Market Analysis Information Database'') in 1984. The comp ...

Cambridge Computer Laboratory
The Department of Computer Science and Technology, formerly the Computer Laboratory, is the computer science department of the University of Cambridge. it employed 35 academic staff, 25 support staff, 35 affiliated research staff, and about 155 research students. The current Head of Department is Professor Ann Copestake.

The new laboratory was housed in the North Wing of the former Anatomy School, on the New Museums Site. Upon its foundation, it was intended "to provide a computing service for general use, and to be a centre for the development of computational techniques in the University". The Cambridge Diploma in Computer Science was the world's first postgraduate taught course in computing, starting in 1953. In October 1946, work began under Maurice Wilkes on EDSAC (''Electronic D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedgwick Museum
The Sedgwick Museum of Earth Sciences, is the geology museum of the University of Cambridge. It is part of the Department of Earth Sciences and is located on the university's Downing Site in Downing Street, central Cambridge, England. The Sedgwick Museum is the oldest of the eight museums which make up the University of Cambridge Museums consortium. History Construction and opening Dr John Woodward collected and catalogued over 35 years nearly 10,000 specimens in five walnut cabinets, two of which he bequeathed to the university in his will. The university later purchased another two, and the fifth was added in the 1840s. The cabinets are still in use today. He also left funds to establish the position of the Woodwardian Professor of Geology. Adam Sedgwick began the process of expanding the collection, and purchased several ichthyosaur skeletons from Mary Anning. He persuaded the university to set aside space in the Cockerill Building, but by the time he died, the collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
