A Library for Support Vector Machines. LIBSVM -- A Library for Support Vector Machines Chih-Chung Chang and Chih-Jen Lin Version 3.20 released on November 15, 2014.

A Library for Support Vector Machines

It conducts some minor fixes. LIBSVM tools provides many extensions of LIBSVM. Please check it if you need some functions not supported in LIBSVM. We now have a nice page LIBSVM data sets providing problems in LIBSVM format. A practical guide to SVM classification is available now! To see the importance of parameter selection, please see our guide for beginners. Using libsvm, our group is the winner of IJCNN 2001 Challenge (two of the three competitions), EUNITE world wide competition on electricity load prediction, NIPS 2003 feature selection challenge (third place), WCCI 2008 Causation and Prediction challenge (one of the two winners), and Active Learning Challenge 2010 (2nd place).

Introduction LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM).

SVM-Light Support Vector Machine. Database Mining Tutorial. What's Database Text Mining?

Database Mining Tutorial

This tutorial shows how to use a relational database management system (RDBMS) to store documents and LingPipe analyses. It uses MEDLINE data as the example data, and MySQL as the example RDBMS. As in the MEDLINE Parsing and Indexing Demo, the LingPipe MedlineParser is used to parse the data from an XML file. Scripts are provided to create the database and database tables. This tutorial is aimed at the novice database programmer, and therefore the database design and the way that the program interacts with the database have been kept as simple as possible. For expository purposes, we break this task into three parts: Loading MEDLINE data into the database, using the LingMed MEDLINE parser and the JDBC API to access a RDBMS.Using the LingPipe API to annotate text data in the database, and to store the annotations back into the database.SQL database queries over the annotated data.

Querying DBpedia The DBpedia data set enables quite astonishing query answering possibilities against Wikipedia data. 1.1. Public SPARQL Endpoint There is a public SPARQL endpoint over the DBpedia data set at The endpoint is provided using OpenLink Virtuoso as the back-end database engine. There is a list of all DBpedia data sets that are currently loaded into the SPARQL endpoint. You can ask queries against DBpedia using: the Leipzig query builder at the OpenLink Interactive SPARQL Query Builder (iSPARQL) at the SNORQL query explorer at (does not work with Internet Explorer); or any other SPARQL-aware client(s). Fair Use Policy: Please read this post for information about restrictions on the public DBpedia endpoint.
