What is NetMiner?
NetMiner is a software tool for exploratory analysis and visualization of large network data. NetMiner 4 embed internal Python-based script engine which equipped with the automatic Script Generator for unskilled users. Then the users can operate NetMiner 4 with existing GUI or programmable script language.
Key Features
Expressive Network Data Model
NetMiner has data structure that can express various types of nodes, links, node attributes and link attributes. In this flexible data structure, almost any social events and research topics can be modelled for network analysis.
Large Scale Network Data Processing
With proper license, computing power, and some algorithmic limitation, NetMiner can handle over 1,000,000 nodes and 10,000,000 links.
Comprehensive Network Measures and Methods
In NetMiner, about 140 analysis modules are mounted. There are 26 modules for data transformation, 66 modules for network analysis, 19 modules for statistical analysis, and 37 modules for network visualization and chart.
Standardized Option and Output Process
All of the analysis sessions in NetMiner are composed of five common analysis components that support standardized analysis process: input, pre-process, main-process, post-process, and output.
Intuitive User Interface
NetMiner is driven by GUI and provides intuitive workflow management interface for complicated analysis.
NetMiner Script Environment
NetMiner provides a python-based script environment. This can access most functions of NetMiner including data management, network analysis, and visualization. Users can create his or her own custom plugins by NetMiner script.
Mix and Match of Numerical and Graphical Output
Exploratory analysis based on the results is available on the graphical output panel. With this visual exploration, intuitive and dynamic interpretation of network analysis results is available.
Integrated Environment for Statistical Analysis
NetMiner provides built-in methods for statistical analysis and visualization.

Data Structure
A DataSet, composed of individual data items, is a basic unit for analysis and visualization in NetMiner. A DataSet is used as an input data for all the analysis and visualization Modules in NetMiner. A DataSet is composed of four types of data items: Main Nodeset, Sub Nodeset, 1-mode Network data and 2-mode Network data. A DataSet contains only one Main Nodeset. But multiple 1-mode Network data can be contained in a DataSet. A DataSet contains multiple Sub Nodesets and multiple 2-mode Network data for each Sub Nodeset can be contained in a DataSet.
ProcessLogs which are generated in the analysis and visualization process can be managed with the DataSet that is used for these analysis and visualization processes in a Workfile.
A Project contains independent multiple Workfiles. Number of Main Nodes in each Workfile does not need to be the same. In this way, the hierarchy of NetMiner data structure is as follow:
Project > Workfile > Dataset > Data items
Even if you perform a data analysis in NetMiner using only one data item, you need to recognize the hierarchy of data structure in NetMiner. The basic data file extension ‘NMF’ represents the Project which is in the highest level in the hierarchy of data structure. If you ‘open’ a NMF file, you need to select a Workfile to use in the analysis and then select data item(s) for each analysis and visualization module. Each level in the hierarchy of data structure in NetMiner will be covered in the following topics.
