TEXTrend ( lead by George Kampis, Eötvös University, Hungary develops a framework for the easy and flexible integration, configuration, and extension of plugin-based components in support of natural language processing (NLP), classification/mining, and graph algorithms for the analysis of business and governmental text corpuses with an inherently temporal component (Kampis, Gulyas et al. 2009). TEXTrends recently adopted OSGi/CIShell for the core architecture and the first seven plugins are IBMs Unstructured Information Management Architecture (UIMA) (, the data mining, machine learning, classification and visualization toolset WEKA (, Cytoscape, Arff2xgmml converter, R ( via iGgraph and scripts (, and yEd. Upcoming work will focus on integrating the Cfinder clique percolation analysis and visualization tool (, workflow support, and web services.

Note that the Sci2 Sci2 Tool uses plugins from several other efforts/tools such as the Information Visualization cyberinfrastructure (, the Network Workbench (, and TEXTrend. As the functionality of OSGi/CIShell-based software frameworks improves and the number and diversity of dataset and algorithm plugins increases, the capabilities of custom tools will expand.
