What is NOESIS?
The NOESIS open-source framework for network data mining provides a large collection of network analysis techniques, including the analysis of network structural properties, community detection methods, link scoring and prediction techniques, and network visualization algorithms. NOESIS includes a complete graphical user interface, but it can also be included in other software projects as a lightweight library, since it is distributed under a permissive BSD license.

Several network analysis measures: degree, eccentricity, average path length, closeness, decay, betweenness, PageRank, HITS, eigenvector centrality, Katz centrality, clustering coefficient, connected components, link betweenness, link embeddedness, link neighborhood overlap...
Different supported network file formats: GML, GraphML, and GDF, among others. Networks can be exported to some image formats, including SVG, PNG, and JPEG format.
A large number of random network models: Erdös-Renyi, Gilbert, Watts-Strogatz, Barabasi-Albert, and Price models. Other models, including regular models, are also available.
Different community detection methods: Kernighan-Lin, Newman-Girvan, Radicchi, hierarchical, fast greedy, spectral, or BigCLAM community detection, among others.
Several link scoring and prediction scores, such as Adamic-Adar score, Resource Allocation index, Katz score, or different random walk-based metrics.
Graphical user interface
Even though NOESIS is provided as a library to be reused in other software development projects, it also includes an easy-to-use graphical user interface. The NOESIS Network Analyzer can be used as an alternative to well-known SNA tools such as Gephi, Pajek, UCINET, or NodeXL. You can load and visualize your own networks and use all the data mining techniques implemented in the NOESIS framework using its GUI. Network visualization can be customized for nodes and links based on their attributes and different network layout algorithms are also available.
The NOESIS framework relies on the iKor library of reusable software components, which provides a customizable collection framework, support for the execution of parallel algorithms, mathematical routines, and the application generator used to build the NOESIS GUI. This is the only external dependency of the NOESIS framework, a deliberate decision to keep it lightweight and facilitate its integration in other software projects.
