Where do weak signals come from, and how do they become strong signals? Signals must have sources. Many new ideas are conceived not by one individual or isolated team, but by many individuals and teams that may or may not be aware of each other's work.
But where do the new ideas come from? Growth of a Weak Signal All of the messages whose synthesis will result in a new weak signal or idea come to us from the past.
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 and text analytics 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. The term is roughly synonymous with text mining; indeed, Ronen Feldman modified a 2000 description of "text mining" in 2004 to describe "text analytics.
" The latter term is now used more frequently in business settings while "text mining" is used in some of the earliest application areas, dating to the 1980s, notably life-sciences research and government intelligence. History Text analysis processes Text mining. After creating a free account, users can submit requests for mining and analyzing JSTOR content.

Les outils de text-mining ont pour vocation d’automatiser la structuration des documents peu ou faiblement structurés. Ainsi, à partir d’un document texte, un outil de text-mining va générer de l’information sur le contenu du document.

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. 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.
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. Theeasybee.com. 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).
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. The entire archive, which is almost 100GB uncompressed, has unigrams (n=1) through fivegrams (n=5). The data set is offered through the LDC for those who are interested (link). As soon as I got my hands on the data, I quickly got to work on some straight forward visualizations. These visual comparisons allow us to see differences in how the two subjects are used - both where they are similar and diverge. I also created a little series of visualizations that shows how six common subjects are used. 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.
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.

La recherche d'information (RI) 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. Carrot Search: document clustering and visualization software.

With the continued growth of your organization, the people and hardware deployed to ensure that it remains in working order is essential, yet the threat picture of your “environment” is not always clear or complete. Maltego 3.
