  • Analyzer includes data-mining functions provided by NetMiner module.

     NetMiner extracts Frequent Itemsets and Association Rules from databases generated by NetLogger, stores them into another database and applies SQL queries to filter the results. SQL queries are read from an XML file (i.e. netminer.xml) and can be increased and updated simply editing that file.

    This module is not intended to perform real-time analysis.  

    Overview

      

    NetMiner is a module that performs data-mining operations inside Analyzer.

      

     It is made up of three distinct tools:

     
     
    • the user interface, which is integrated into Analyzer executable and it is  activated from the NetMiner menu;
     
    • the data extraction, transformation and loading utility, which is supplied  as an external command-line utility (dbetl.exe) and that could be used also  apart from Analyzer;
     
    • the Apriori implementation, supplied as an external command-line utility  (apriori.exe),  developed by C.Borgelt of university of  Magdeburg, which implements the data mining algorithm.
     
     

    NetMiner user interface provides a simple way to handle the extraction of frequent itemsets and association rules from traffic transactions stored into NetLogger databases.

     

    The picture below shows the workflow for the extraction of data-mining results.

     

    

     
     
    1. The traffic is logged through NetLogger agent, then the transactions are extracted and transformed into a format  suitable for data-mining by running the  NetMiner wizard.
     
    2. The Apriori algorithm is applied to extract association rules or frequent  itemsets (or both).
     
    3. The results are transformed and loaded into a destination database.
     
    4. The NetMiner.xml file is processed, thus creating a set of SQL views on  the mining database.
     
    5. The results can be analyzed from the NetMiner user interface.
