Data mining

Browser Automation. Web mining. 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

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. Text mining. After creating a free account, users can submit requests for mining and analyzing JSTOR content.

Text mining

By submitting a query, a user will receive a random sample of 1,000 of JSTOR's 4.6 million documents; more documents can be received by contacting JSTOR directly. Users can choose to receive the following results: Fouille de textes. Un article de Wikipédia, l'encyclopédie libre.

Fouille de textes

La fouille de textes ou "l'extraction de connaissances" dans les textes est une spécialisation de la fouille de données et fait partie du domaine de l'intelligence artificielle. Cette technique est souvent désignée sous l'anglicisme text mining. Announcing the PLOS Text Mining Collection | EveryONE. Hello there!

Introduction au Text-mining

Ainsi, à partir d’un document texte, un outil de text-mining va générer de l’information sur le contenu du document. Cette information n’était pas présente, ou explicite, dans le document sous sa forme initiale, elle va être rajoutée, et donc enrichir le document. A quoi cela peut bien servir ? ClearForest Gnosis. KEEL: A software tool to assess evolutionary algorithms for Data Mining problems (regression, classification, clustering, pattern mining and so on) National Centre for Text Mining — Text Mining Tools and Text Mining Services. Sipina Research -- Classification Trees Software. Retail + Social + Mobile = @WalmartLabs. Eric Schmidt famously observed that every two days now, we create as much data as we did from the dawn of civilization until 2003.

Retail + Social + Mobile = @WalmartLabs

A lot of the new data is not locked away in enterprise databases, but is freely available to the world in the form of social media: status updates, tweets, blogs, and videos. At Kosmix, we’ve been building a platform, called the Social Genome, to organize this data deluge by adding a layer of semantic understanding. Conversations in social media revolve around “social elements” such as people, places, topics, products, and events. For example, when I tweet “Loved Angelina Jolie in Salt,” the tweet connects me (a user) to Angelia Jolie (an actress) and SALT (a movie). By analyzing the huge volume of data produced every day on social media, the Social Genome builds rich profiles of users, topics, products, places, and events. KNIME | Konstanz Information Miner. Center for Intelligent Information Retrieval. Chris Harrison - Web Trigrams Visualization. Back in late 2006, Google released a massive set of web n-gram data (basically pieces of sentences).

Chris Harrison - Web Trigrams Visualization

A trigram (n=3), for example, might be "I like food" or "frog is tasty. " Each n-gram is also labeled with the number of times it appeared in Google's corpus. Cluster Execution. Compute clusters often run idle because of a lack of applications that can be run in the cluster environment and the enormous effort required to operate, maintain, and support applications on the grid.

Cluster Execution

KNIME Cluster Execution tackles this problem by providing a thin connection layer between KNIME and the cluster, which allows every node running in KNIME and every application integrated in KNIME to be executed on the cluster. Submission of data to the cluster and collection of the results is made very simple. Long-running analysis workflows can be executed on the compute cluster, thus releasing local resources for other productive work. Recherche d'information. Un article de Wikipédia, l'encyclopédie libre. La recherche d'information (RI[1]) est le domaine qui étudie la manière de retrouver des informations dans un corpus.

Celui-ci est composé de documents d'une ou plusieurs bases de données, qui sont décrits par un contenu ou les métadonnées associées. Les bases de données peuvent être relationnelles ou non structurées, telles celles mises en réseau par des liens hypertexte comme dans le World Wide Web, l'internet et les intranets. Le contenu des documents peut être du texte, des sons, ses images ou des données. Carrot Search: document clustering and visualization software. AlchemyAPI - Transforming Text Into Knowledge.
