Data Mining: What is Data Mining?

Data Mining: What is Data Mining?
Overview Generally, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and summarizing it into useful information - information that can be used to increase revenue, cuts costs, or both. Data mining software is one of a number of analytical tools for analyzing data. It allows users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational databases. Continuous Innovation Although data mining is a relatively new term, the technology is not. Example For example, one Midwest grocery chain used the data mining capacity of Oracle software to analyze local buying patterns. Data, Information, and Knowledge Data Data are any facts, numbers, or text that can be processed by a computer. Information Knowledge Data Warehouses What can data mining do?

Text mining : vers un nouvel accord avec Elsevier | Sciences communes La semaine est placée sous le signe de la divulgation de documents officiels sur le text mining (pourrait-on parler de MiningLeaks ?). Le collectif Savoirscom1 vient de publier le rapport du Conseil supérieur de la propriété littéraire et artistique sur « l’exploration de données ». De mon côté, j’apporte quelques informations sur l’accord conclu entre le consortium Couperin et Elsevier concernant la licence de data et text mining accordée par le géant de l’édition scientifique à plusieurs centaines d’établissements universitaires et hospitaliers français. Contre toute attente, les nouvelles sont meilleures du côté d’Elsevier que du CSPLA : en digne représentant des ayants-droits, le Conseil vient de retoquer toute éventualité d’exception au droit d’auteur pour les projets scientifiques de text mining (alors que le Royaume-Uni vient tout juste d’en voter une, et qu’il s’agit d’un des principaux axes des projets de réforme européens du droit d’auteur). Ce projet initial a été clarifié.

Text mining A typical application is to scan a set of documents written in a natural language and either model the document set for predictive classification purposes or populate a database or search index with the information extracted. Text mining and text analytics[edit] The term text analytics describes a set of linguistic, statistical, and machine learning techniques that model and structure the information content of textual sources for business intelligence, exploratory data analysis, research, or investigation.[1] The term is roughly synonymous with text mining; indeed, Ronen Feldman modified a 2000 description of "text mining"[2] in 2004 to describe "text analytics The term text analytics also describes that application of text analytics to respond to business problems, whether independently or in conjunction with query and analysis of fielded, numerical data. History[edit] Text analysis processes[edit] Subtasks — components of a larger text-analytics effort — typically include: Software[edit]

What is Data Mining? A Webopedia Definition Main » TERM » D » By Vangie Beal Data mining requires a class of database applications that look for hidden patterns in a group of data that can be used to predict future behavior. For example, data mining software can help retail companies find customers with common interests. The phrase data mining is commonly misused to describe software that presents data in new ways. Data mining is popular in the science and mathematical fields but also is utilized increasingly by marketers trying to distill useful consumer data from Web sites.

Consortium of 325 institutions working together to acquire and preserve social science data. Maintained at University of Michigan, ICPSR receives, processes, and distributes data on social phenomena in 130 countries.

Data for Research (dfr.jstor.org) Data for Research (dfr.jstor.org) is a free, self-service tool that allows computer scientists, digital humanists, and other researchers to select and interact with content on JSTOR. Created in 2008, Data for Research enables exploration of both scholarly journal literature (more than 7 million journal articles) and a set of primary resources (26,000 19th Century British Pamphlets). The resource consists of a set of web-based tools, including: a powerful faceted search interface that can be leveraged to define content of interest through an iterative process of searching and results filtering word frequencies, citations, key terms, and ngrams utilized for conducting analysis of document-level data topic modeling (classification of subject headings at the article level), a powerful tool for content selection and filtering downloadable datasets containing word frequencies, citations, key terms, or ngrams associated with the content selected visualization tools
