5 Best Free Data Mining Software For Windows

Here is a list of Best Free Data Mining Software For Windows. These software are used to perform various data mining operations in order to extract useful information from datasets. The supported file formats to import datasets include CSV, ARFF, DATA, TXT, XLS, etc. files. Most of these provide a set of sample dataset files which you can import for analysis.

In terms of operations, these let you perform data manipulation, classification, association, regression, clustering, modeling, and data visualization. Each of these provide several algorithm to support respective tasks. For example, for Clustering, you can use K-Means, Kohonen-SOM, LVQ, Neighborhood Graph, etc. algorithms. For Association, you can apply A priori, A priori MR, A priori PT, Assoc Outlier, Frequent Itemsets, etc. rules. For Data Visualization, Scaterrplots, Box Plot, Distribution, Heat Map, etc. methods can be used, and so on. One of these is a text data mining software which lets you analyze text data using various methods.

The results can be viewed on the interface and can also be saved as reports in different formats. All in all, these are good software that you can use for data mining tasks for free.

My Favorite Data Mining Software For Windows:

I quite liked Weka as it provides all sufficient tools to perform primary data mining tasks. It is also not that difficult to use. Orange is also good for professionals as it provides a unique approach to perform data mining operations which is by using widgets.

Data Mining with Weka:

Here are the applications which divide data mining tasks into easily manageable sections:

  • Explorer: This application is used for data pre processing, data classification, data clustering, association, and data visualization. You can open data files in several formats including arff, data, CSV, JSON, Matlab ASCII files, dat, etc. You can also open a set of instances from a URL or database. It also provides a tool called DataGenerator to generate artificial data. Various classifier rules can be chosen from, including DecisionTable, OneR, PART, ZeroR, etc. EM, Canopy, Cobweb, FarthestFirst, FilteredClusterer, HierarchicalClusterer, SimpleKMeans, etc. clustering algorithms are available to select from. Association rules including Apriori, FilteredAssociator, and FPGrowth can be used. It provides a tab called Select attributes which basically evaluates relevance of attributes. For this, you can select an attribute evaluator (CfsSubsetEval, ClassifierAttributeEval, OneRAttributeEval, InfoGainAttributeEval, etc.) and a method (GreedyStepwise, BestFirst, Ranker). The respective output is displayed in respective tabs for each of aforementioned tasks.
  • KnowledgeFlow: It performs same data mining processes as mentioned in Explorer, but with more tools. It handles data either incrementally or in batches. Some of its features include: chain filtering together, showing models produced by classifiers for each fold in a cross validation, and visualizing performance of incremental classifiers during processing. Here, you also get numerous data visualization methods including Text Viewer, Image Viewer, Attribute Summarizer, Strip Chart, Model Performance Chart, Boundary Plotter, Scatter Plot Matrix, Graph Viewer, and Cost Benefit Analysis.
  • Experimenter: Using this application, you can create, run, and analyse experiments of different types including cross validation, train/test percentage split, random split result, learning rate result, etc. You can define a dataset, specify iteration controls, and choose an algorithm to perform experiment.

A Workbench application is also provided which is used to perform same tasks as mentioned in above applications.

All in all, it is a nice free data mining software. It is also not that tough to operate but if you still have difficulty, you can check this video tutorial in order to view detailed explanations of tasks.
