Data mining

Data mining is an interdisciplinary subfield of computer science. It is the computational process of discovering patterns in large data sets ("big data") involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. Data mining is the analysis step of the "knowledge discovery in databases" process, or KDD.

The term is a misnomer, because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction (mining) of data itself. It also is a buzzword and is frequently applied to any form of large-scale data or information processing (collection, extraction, warehousing, analysis, and statistics) as well as any application of computer decision support system, including artificial intelligence, machine learning, and business intelligence. The book Data mining: Practical machine learning tools and techniques with Java (which covers mostly machine learning material) was originally to be named just Practical machine learning, and the term data mining was only added for marketing reasons. Often the more general terms (large scale) data analysis and analytics – or, when referring to actual methods, artificial intelligence and machine learning – are more appropriate.

Domain name

A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names can also be thought of as a location where certain information or activities can be found.

Domain names are used in various networking contexts and application-specific naming and addressing purposes. In general, a domain name represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2014, the number of active domains reached 271 million.

Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, info, net, edu, and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users who wish to connect local area networks to the Internet, create other publicly accessible Internet resources or run web sites. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.

Information Sciences Institute

The USC Information Sciences Institute (ISI), a unit of the University of Southern California (USC) Viterbi School of Engineering, is located in Marina del Rey, California. It researches and develops information processing, computing and communications technologies.

ISI actively participated in the information revolution, including helping to develop and manage the Internet. The Institute conducts basic and applied research supported by more than 20 U.S. government agencies involved in defense, science, health, homeland security, energy and other areas. Annual funding is about $60 million.

The USC Andrew and Erna Viterbi School of Engineering was ranked among the nation’s top 10 engineering graduate schools by US News & World Report in 2015. Including ISI, USC is ranked first nationally in federal computer science research and development expenditures.

ISI employs about 350 research scientists, research programmers, graduate students and administrative staff at its Marina del Rey, California headquarters and in Arlington, Virginia. About half of the research staff hold PhDs, and about 40 are research faculty who teach at USC and/or advise graduate students. Several senior researchers are tenured USC faculty in the Viterbi School.

University of Southern California

The University of Southern California (USC or SC) is a private, not-for-profit, and nonsectarian research university founded in 1880 with its main campus in the city area of Los Angeles, California. As California's oldest private research university, USC has historically educated a large number of the region's business leaders and professionals. In recent decades, the university has also leveraged its location in Los Angeles to establish relationships with research and cultural institutions throughout Asia and the Pacific Rim. An engine for economic activity, USC contributes approximately $5 billion annually to the economy of the Los Angeles county area.

For the 2014-2015 academic year, there were 18,740 students enrolled in four-year undergraduate programs. USC is also home to 23,729 graduate and professional students in a number of different programs, including business, law, engineering, social work, and medicine. The university has a "very high" level of research activity and received $687 million in sponsored research from 2014 to 2015. Multiple rankings list the University of Southern California as being among the top 25 universities in the United States.
