'''NetMiner''' is an application software for exploratory analysis and visualization of large network data based on [[Social network analysis|SNA (Social Network Analysis)]]. It can be used for general research and teaching in social networks. This tool allows researchers to explore their network data visually and interactively, helps them to detect underlying patterns and structures of the network.<ref>{{cite book|last=Furht|first=Borko|title=Handbook of Social Network Technologies and Applications|year=2010|publisher=Springer Press|isbn=978-1-4419-7141-8|pages=19|url=https://books.google.com/books?id=7kCOwGMC46cC}}</ref>
It features [[data transformation]], network analysis, statistics, visualization of network data, chart, and a [[programming language]] based on the [[Python (programming language)|Python script language]]. Also, it enables users to import unstructured text data(e.g. news, articles, tweets, etc.) and extract words and network from text data. In addition, NetMiner SNS Data Collector, an extension of NetMiner, can collect some social networking service(SNS) data with a few clicks.


It has been released in 2001 as a commercial analysis software specialized in [[social network analysis]]. There are various license not only for commercial use, but also for non-commercial academic use.<ref>[http://www.netminer.com/download_buy/license_price/license_price.do NetMiner website(www.netminer.com) > License]</ref> The current version is 4 for [[Microsoft Windows]] ([[Windows 2000|2000]] or later version).<ref>[http://www.netminer.com/product/systemrequirement.do NetMiner website(www.netminer.com) > System Requirements]</ref>
=='''Script Workbench in NetMiner 4'''==


<br />
NetMiner 4 equips Script Workbench based on [[Python (programming language)|Python script language]] with Script Generator which enbles users to generate a programming script automatically. Then users can operate functions in NetMiner 4 by using GUI or programmable script lanague.
Most features of NetMiner can be performed using a script rather than clicking a menu so that complicated series of commands can be stored in scripts and executed repeatedly without additional work. Analysis flows, such as loops and conditional branching can be controlled by a user in a flexible way. Also, various existing libraries for mathematics and statistics written by Python can be applicable within NetMiner 4 without any modifications, and ordinary data structures which whar provided by Python can be defined. Users can develop their own algorithms by combinations of NetMiner features. In addition, a generated script file can be added to NetMiner 4 as a one of menu by a form of plug-in which can be shared with other NetMiner users as well.


==Release history==
===Features of NetMiner Script===
The first version of NetMiner was released on Dec 21, 2001. There have been four major updates from 2001.


lA DER/FJ
====Python-based Scripting====
Most analysis software packages with scripting feature use their own scripting language. It requires users to learn the language. NetMiner Script is based on Python which is a programming language distributed for free and widely used. Python's syntax is well known to be quite intuitive and easy to pick up for new programmers. <ref>{{cite news|last=Bloom|first=Brian|title=Python simplifies big data|url=http://www.itworldcanada.com/news/python-simplifies-big-data/146321|accessdate=31 October 2012|newspaper=ComputerWorld Canada|date=26 October 2012}}</ref><ref>{{cite news|last=Jackson|first=Joab|title=Python - Big Data's secret power tool|url=http://www.computerworlduk.com/in-depth/applications/3407943/python-big-datas-secret-power-tool/|accessdate=31 October 2012|newspaper=IDG News Service|date=30 October 2012}}</ref> Also, there are many libraries for mathematics or statistics written by Python and these libraries can be imported to NetMiner 4 and used with modules in NetMiner 4 without any additional programming. Using loops, conditionals, the in-depth analysis is available. And users can create a batch file which is executed automatically for NetMiner.
====WYSIWYG Scripting====
NetMiner provides user-friendly enviroment with GUI(Graphic User Interface) and NetMiner Script is a GUI-based script. It means all tasks executed through GUI can be controlled and expressed by script language. Modules in NetMiner 4 are executed in identical ways regardless of the interface. In addition, NetMiner 4 provides Script Generator which generates the script code automatically by clicking items on GUI which is the same as GUI of NetMiner.

==Data structure==


===Hierarchy of NetMiner data structure===
=='''Data Structure'''==


A DataSet is a basic unit in NetMiner and used as an input data for all the analysis and visualization Modules. 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 can have only one Main Nodeset. But multiple 1-mode Network data can be contained in a DataSet. Moreover, a DataSet contains multiple Sub Nodesets and multiple 2-mode Network data. ProcessLogs which are generated by analysis and visualization process can be managed with a DataSet in a Workfile. A Project contains independent multiple Workfiles. A number of nodes in Main NodeSet of each workfile does not need to be the same. In this way, the hierarchy of NetMiner data structure is as follow:

==Script workbench in NetMiner 4==
A DataSet, composed of data items, is a basic unit 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 can have only one Main Nodeset. But multiple 1-mode Network data can be contained in a DataSet. Also a DataSet contains multiple Sub Nodesets and multiple 2-mode Network data. ProcessLogs which are generated by analysis and visualization process can be managed with the DataSet in a Workfile. A Project contains independent multiple Workfiles. A number of nodes in Main NodeSet of 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'''


=== Data Item ===

====Nodeset====
Nodeset refers to a group of nodes which have common characteristics.

====Network Data====
Network data in NetMiner refers to the data which represents a relationships between nodes. It can be formd as a matrix or a link list. A relationship between nodes in one nodeset is allowed only for a main nodeset, and called 1-mode network. A relationship between nodes in more than two nodesets can be defined as a relationship between main nodeset and sub nodeset and is called 2-mode network.

====Attribute of Node and Link====
Attributes can be defined for node or link in NetMiner. Attributes can be as numbers, text, datetime, time, and have missing value. The attribute is used for network data analysis or visualization. Specific modules of NetMiner require attributes as one of input data. Using the attribute of node or link, it is available to extract some sub network from whole network data. Also it is used for styling network maps.


===Dataset===

====Multiple Sub Nodeset====
A dataset can contain multiple nodesets. In NetMiner, nodesets are divided into two types: main nodeset and sub nodesets. Only a single nodeset can be defined as a main nodeset and the rest is defined as sub nodesets in a dataset.

====Multiple Network Data (Layer)====
A dataset can include multiple network data. 1-mode network data refers to relationship between nodes in a main nodeset. More than two seperate network data can be defined under a main nodeset. For example, there are six nodes {A, B, C, D, E, F} in a main nodeset, more than two network data named "love", "hate" can be defined as follow,

* 1-mode Network 1 (Love) = {(A,B), (A,C), (B,D), (C,E)}
* 1-mode Network 2 (Hate) = {(A,C), (B,C), (D,E), (A,E)}

A group of networks under a nodeset is called a network layer in NetMiner. There can be 1-mode network layers under a main nodeset, and 2-mode network layers under a main nodeset and a specific sub nodesets. Multiple network data(layers) in a nodeset can be integrated in analysis and visualization process.


=== Workfile ===

Workfiles are composed of a dataset and a process log. NetMiner uses a concept of a workfile to manage a dataset and module process simultaneously. A process log shows traces of process execution, and is composed of Session, QuerySets, and Selections. When a module is opened, a session is created and added to a list. And when a query or a selection is saved, it is added to the list.


=== Project ===

A NetMiner data file (.NMF) corresponds to a single project. In a project, there can be more than one workfile. There are two reasons for grouping multiple workfiles in a single project file.
A new workfile is created when any changes of composition of nodes occur in a main nodeset by intentional control or executed process. Workfiles can be managed in a tree structure. So users can track history of data changes using the workfile tree.
