Piwik is an open source web analytics platform.
Piwik displays reports regarding the geographic location of visits, the source of visits (i.e. whether they came from a website, directly, or something else), the technical capabilities of visitors (browser, screen size, operating system, etc.), what the visitors did (pages they viewed, actions they took, how they left), the time of visits and more.
In addition to these reports, Piwik provides some other features that can help users analyze the data Piwik accumulates, such as:
*Annotations — the ability to save notes (such as one's analysis of data) and attach them to dates in the past.
*Transitions — a feature similar to Click path-like features that allows one to see how visitors navigate a website, but different in that it only displays navigation information for one page at a time.
*Goals — the ability to set goals for actions it is desired for visitors to take (such as visiting a page or buying a product). Piwik will track how many visits result in those actions being taken.
*E-commerce — the ability to track if and how much people spend on a website.
*Page Overlay — a feature that displays analytics data overlaid on top of a website.
*Row Evolution — a feature that displays how metrics change over time within a report.
*Custom Variables — the ability to attach data, like a user name, to visit data. +

R
R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible.
R is available as Free Software for data manipulation, calculation and graphical display. It includes
*an effective data handling and storage facility,
*a suite of operators for calculations on arrays, in particular matrices,
*a large, coherent, integrated collection of intermediate tools for data analysis,
*graphical facilities for data analysis and display either on-screen or on hardcopy, and
*a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities.
R can be considered as an environment within which statistical techniques are implemented. R can be extended via packages. For example, try:

Semantic Drilldown is an extension to Semantic MediaWiki (SMW) that provides a page for drilling down through a site's data, using categories and filters on semantic properties. The list of pages in each top-level category can be viewed, and for each such category, filters can be created that cover a specific semantic property. If filters exist for a category, users can click on the different possible values for those filters, narrowing the set of results, and thus drill down through the data. +

The goal of the SEMantic simILARity software toolkit (SEMILAR; pronounced the same way as the word 'similar') is to promote productive, fair, and rigorous research advancements in the area of semantic similarity. The kit is available as application software or as Java API.
As of March 2014, the GUI-based SEMILAR application is only available to a limited number of users who commit to help improving the usability of the interface. The JAVA libray (API) however, can be downloaded.
SEMILAR comes with various similarity methods based on Wordnet, Latent Semantic Analysis (LSA), Latent Dirichlet Allocation (LDA), BLEU, Meteor, Pointwise Mutual Information (PMI), Dependency based methods, optimized methods based on Quadratic Assignment, etc. And the similarity methods work in different granularities - word to word, sentence to sentence, or bigger texts. Some methods have their own variations which coupled with parameter settings and your selection of preprocessing steps could result in a huge space of possible instances of the same basic method. +

Tableau software helps people communicate data through an innovation called VizQL, a visual query language that converts drag-and-drop actions into data queries, allowing users to quickly find and share insights in their data. With Tableau, “data workers” first connect to data stored in files, cubes, databases, warehouses, Hadoop technologies, and even some cloud sources like Google Analytics. They then interact with the Tableau user interface to simultaneously query the data and view the results in charts, graphs, and maps that can be arranged together on dashboards.

'''Quotes''' from the [http://eric.univ-lyon2.fr/~ricco/tanagra/index.html official home page] (10/2014):
* TANAGRA is a free DATA MINING software for academic and research purposes. It proposes several data mining methods from exploratory data analysis, statistical learning, machine learning and databases area.
* The main purpose of Tanagra project is to give researchers and students an easy-to-use data mining software, conforming to the present norms of the software development in this domain (especially in the design of its GUI and the way to use it), and allowing to analyse either real or synthetic data.
* The second purpose of TANAGRA is to propose to researchers an architecture allowing them to easily add their own data mining methods, to compare their performances. TANAGRA acts more as an experimental platform in order to let them go to the essential of their work, dispensing them to deal with the unpleasant part in the programmation of this kind of tools : the data management.
* The third and last purpose, in direction of novice developers, consists in diffusing a possible methodology for building this kind of software. They should take advantage of free access to source code, to look how this sort of software is built, the problems to avoid, the main steps of the project, and which tools and code libraries to use for. In this way, Tanagra can be considered as a pedagogical tool for learning programming techniques.
According to its author, Tangara can be compared to [[Weka]]: In comparison it has an easier to use Interface, but less functionality. +
