Massimo Marchiori (Padua, 1970) is an Italian mathematician and computer scientist.
In July, 2004, he was awarded the TR35 prize by Technology Review (the best 35 researchers in the world under the age of 35). [1]
He is Professor in Computer Science at the University of Padua, and Research Scientist at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) in the World Wide Web Consortium.[ citation needed ]
He was the creator of HyperSearch, a search engine where the results were based not only on single page ranks, but on the relationship between single pages and the rest of the Web. Afterwards, Google co-founders Larry Page and Sergey Brin cited HyperSearch when they introduced PageRank. [2]
He has been chief editor of the world standard for privacy on the Web (P3P), and co-author of the companion APPEL specification. [3]
Initiator of the Query Languages effort at W3C (see for instance QL'98 [4] ), he started the XML-Query project, deemed to develop the corresponding world standard for querying XML (XQuery), finally providing the due integration between the Web and the database world. [3]
He co-developed the first version of the Web Ontology Language (OWL) standard. [3]
In April 2010 he became the Chief Technology Officer of Atomium Culture. [5]
He was the creator of the social search engine Volunia, launched on February 2012. [6] [7] On 8 June 2012 Marchiori announced, with an open letter, [8] [9] [10] that he had been excluded from the CTO position in the company "because someone else wants to do it instead of me. This person wants to decide everything, without me. And so, he put himself into my shoes, commanding me to step aside".
He created Negapedia, [11] the negative version of Wikipedia.
Google Search is a search engine provided and operated by Google. Handling more than 3.5 billion searches per day, it has a 92% share of the global search engine market. It is the most-visited website in the world. Additionally, it is the most searched and used search engine in the entire world.
Lawrence Edward Page is an American business magnate, computer scientist and internet entrepreneur. He is best known for co-founding Google with Sergey Brin.
Sergey Mikhailovich Brin is an American business magnate, computer scientist, and internet entrepreneur, who co-founded Google with Larry Page. Brin was the president of Google's parent company, Alphabet Inc., until stepping down from the role on December 3, 2019. He and Page remain at Alphabet as co-founders, controlling shareholders, board members, and employees. As of February 2023, Brin is the 9th-richest person in the world, with an estimated net worth of $89.0 billion.
A query language, also known as data query language or database query language (DQL), is a computer language used to make queries in databases and information systems. A well known example is the Structured Query Language (SQL).
Yahoo! Search is a Yahoo! internet search provider that uses Microsoft's Bing search engine to power results, since 2009, apart from four years with Google until 2019.
OpenSearch is a collection of technologies that allow the publishing of search results in a format suitable for syndication and aggregation. Introduced in 2005, it is a way for websites and search engines to publish search results in a standard and accessible format.
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 cannot be indexed and searched by a web search engine falls under the category of deep web.
Google was officially launched in 1998 by Larry Page and Sergey Brin to market Google Search, which has become the most used web-based search engine. Larry Page and Sergey Brin, students at Stanford University in California, developed a search algorithm at first known as "BackRub" in 1996, with the help of Scott Hassan and Alan Steremberg. The search engine soon proved successful and the expanding company moved several times, finally settling at Mountain View in 2003. This marked a phase of rapid growth, with the company making its initial public offering in 2004 and quickly becoming one of the world's largest media companies. The company launched Google News in 2002, Gmail in 2004, Google Maps in 2005, Google Chrome in 2008, and the social network known as Google+ in 2011, in addition to many other products. In 2015, Google became the main subsidiary of the holding company Alphabet Inc.
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.
An RDF query language is a computer language, specifically a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework (RDF) format.
Hyper Search is a method of link analysis for search engines. It was created by Italian researcher Massimo Marchiori.
Rajeev Motwani was an Indian American professor of Computer Science at Stanford University whose research focused on theoretical computer science. He was a special advisor to Sequoia Capital. He was a winner of the Gödel Prize in 2001.
Ranking of query is one of the fundamental problems in information retrieval (IR), the scientific/engineering discipline behind search engines. Given a query q and a collection D of documents that match the query, the problem is to rank, that is, sort, the documents in D according to some criterion so that the "best" results appear early in the result list displayed to the user. Ranking in terms of information retrieval is an important concept in computer science and is used in many different applications such as search engine queries and recommender systems. A majority of search engines use ranking algorithms to provide users with accurate and relevant results.
The Stanford Digital Library Project (SDLP) was a research program run by Hector Garcia-Molina, Terry Winograd, Dan Boneh, and Andreas Paepcke at Stanford University in the mid-1990s to 2004. The team also included librarians Rebecca Wesley and Vicky Reich. The primary goal of the SDLP project was to "provide an infrastructure that affords interoperability among heterogeneous, and autonomous digital library services." and described elsewhere as "to develop the enabling technologies for a single, integrated and "universal" library, proving uniform access to the large number of emerging networked information sources and collections."
Googlization is a neologism that describes the expansion of Google's search technologies and aesthetics into more markets, web applications, and contexts, including traditional institutions such as the library. The rapid rise of search media, particularly Google, is part of new media history and draws attention to issues of access and to relationships between commercial interests and media.
PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank is a way of measuring the importance of website pages. According to Google:
PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.
Volunia was a web search engine created by Massimo Marchiori. It was launched in beta only for registered power users on February 6, 2012 and went live on June 14, 2012. Volunia, dubbed as "the search engine of the future", was speculated to be based on Hyper Search technology. On June 8, 2012, Marchiori announced with an open letter that he had been excluded from his project: six days later, on June 14, 2012, the site went live, but it ceased to operate in February 2014.
The following outline is provided as an overview of and topical guide to search engines.
Rajen Sheth is an executive at Google, where he currently runs product management at cloud AI and machine learning team. The idea of an enterprise version Google's email service Gmail was pitched by Rajen in a meeting with CEO Eric Schmidt in 2004. Schmidt initially rejected the proposal, arguing that the division should focus on web search, but the suggestion was later accepted. Sheth is known as "father of Google Apps", and is responsible for development of Chrome and ChromeOS for Business.
