Netlytic

ReKN Admin — Thu, 18 Dec 2014 19:42:57 +0000

"Netlytic is a cloud-based text and social networks analyzer that can automatically summarize large volumes of text and discover social networks from online conversations on social media sites". Netlytic is designed to assist researchers to "understand an online group’s operation, identify key and influential constituents, and discover how information and other resources flow in a network". Netlytic facilitates the importation of online conversation data, the exploration and identification of emerging themes within the data, and the automatic visualization of chain networks or person name networks. Netlytic facilitates the interrogation of a myriad of social network features: measuring the community's strength, identifying prominent actors versus peripheral participants, analyzing group perceptions, and "sharing information within a network of trust". The application is best suited for analyzing large, online group communities.

Tulip

ReKN Admin — Tue, 16 Dec 2014 21:28:46 +0000

Tulip is an "information visualization framework dedicated to the analysis and visualization of relational data". Tulip aims at facilitating the design of "interactive information visualization applications for relational data" while maintaining enough flexibility to be tailored to address the individual research questions of individual scholars. Tulip is written in C++ framework which enables the development of "algorithms, visual encodings, interaction techniques, data models, and domain-specific visualizations". Tulip's four main project - NOSSI, Porgy, Systrip, and rNav - were all developed in a scientific context but are applicable to other disciplines and fields. The project softwares allow users to create digital renderings of networks in a rich and manipulable environment.

Social Networks Visualizer (SocNetV)

ReKN Admin — Tue, 16 Dec 2014 21:28:18 +0000

"Social Networks Visualizer (SocNetV) is a cross-platform, user-friendly tool for the analysis and visualization of Social Networks". SocNetV allows users to easily create and manipulate social networks on a virtual canvas. SocNetV supports not only the creation and modification of social networks but it also allows users to analyze the "social and mathematical properties, produce reports for these properties and apply visualization layouts for relevant presentation of each network". SocNetV computes network properties and calculates advanced structural measures for social network analysis. SocNetV features a user-friendly interface, strong social network analysis methods, and is entirely free, open-source software.

Cytoscape

ReKN Admin — Tue, 16 Dec 2014 21:27:45 +0000

Cytoscape is an open-source software platform for visualizing networks. While originally developed to visualize molecular interaction and biological pathways, Cytoscape is readily applicable to social science and humanities research: "now it is a general platform for complex network analysis and visualization". The core Cityscape application "provides a basic set of features for data integration, analysis, and visualization". For more specialized research, Cytoscape features a wide variety of add-on applications that expand the capability of the program to answer specific research questions. Cytoscape actively forges an online community through social media and training events in order to connect users and provide support for their project's use of Cytoscape.

Graphviz

ReKN Admin — Tue, 16 Dec 2014 21:26:33 +0000

Graphviz is an "open source graph visualization software" that facilitates the representation of information in the form of an abstract diagram, graph, or network. Graphviz converts "descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages; PDF or Postscript for inclusion in other documents; or display in an interactive graph browser". Users are in complete control of the colour, font, layout, and shape of their visualization. The various shapes or layouts correspond to the type of data and the nature of the research questions being posed. Additionally, Graphviz offers many web-based and interactive interfaces, auxiliary tools, libraries and language bindings.

Gephi

ReKN Admin — Tue, 16 Dec 2014 21:25:25 +0000

Gephi is an "interactive visualization and exploration platform for all kinds of networks and complex systems, dynamic and hierarchical graphs". Described as "Photoshop but for data", Gephi is a "tool for people that have to explore and understand graphs". The aim of Gephi is to "help data analysts to make hypothesis, intuitively discover patterns, isolate structure singularities or faults during data sourcing". Gephi was designed to assist data analysis, link analysis, social network analysis, and biographical network analysis. Some of Gephi's impressive features include: easy node grouping, a manipulative and multi-level layout, real-time user interaction, colour-coded partitioning, and generating of reports on centrality or other calculable characteristics of the network.
