21. IVC Software Framework Docu is at http://iv.slis.indiana.edu/swhttp://iv.slis.indiana.edu/sw ANALYSIS ALGORITHMS generate models from parsing other data structures and/or processing on the data LAYOUT ALGORITHMS run graphical processes on the appropriate model DATA MODEL PERSISTENCE factory to persist a model to a particular data store (i.e. XML format, database) STANDARD MODEL INTERFACES based on Java 2 Swing standard models CODE INTEGRATION new algorithms can be integrated easily by supporting one or more of the models

22. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004.  Framework can run different data analysis and IV algorithms on a standard set of input data formats (tree, matrix, network, table, list).  Models from the algorithms can be serialized through the persistence layer; and it is generic enough for plugging in various persistence options (XML, SQL database, etc).  Based on Model-View- Controller (MVC) by focusing on standard data model interfaces for data exchange.

23. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Demo IVC Software Framework Download from http://iv.slis.indiana.edu/sw/ (code is hosted at Sourceforge.net)http://iv.slis.indiana.edu/sw/ CD contains  Readme.txt  04-iv-ivc.ppt (this slide show)  IVC-www (web pages available via http://iv.slis.indiana.edu/)http://iv.slis.indiana.edu/  IVC-source (IVC source code, needs to be compiled using ant)  IVC-build (contains an executable jar file and sample data)

24. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Run the IVC Software Framework Copy CD content to harddrive In ‘/IVC-build’ double click ‘ivc.jar’ to open the window below Use menu system to  Load or simulate a data set.  Analyze, visualize, or interact with a data set.  To start a toolkit.  To access code reference pages, learning modules, javadoc, get updates, etc.

25. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Whenever an algorithm is selected, the user receives feedback on what algorithm was run, what parameters were used, any textual results, who developed this algorithm, etc. The amount of feedback can be customized. In addition, a log file is generated as a permanent track of all user actions. Each loaded/simulated data set is internally stored as a data model. All data models of a session are listed on the right hand side. Right click a model to rename it.

26. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Only algorithms that can be used with a selected data model are selectable (all others are grayed out).* *The black shown network visualizations are prefuse demo’s that do not (yet) use the IVC data modules but require their own data format.

27. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Currently Available Algorithms Data Modeling  P2P network modeling and search algorithms  - Structured P2P Systems (Content-Addressable Network Model (CAN), Chord Model)  - Unstructured P2P System (PRU Model, Hypergrid Model)  TARL model for the co-evolution of author-paper networks Data Analysis  General Search Algorithm – Breadth First Search, k-Random Walk Search  CAN Search Algorithm, Chord Search Algorithm Visualization  JUNG network layout algorithms  Prefuse demos Interaction  Prefuse demos Toolkits  AW toolkit In Sept 2004, most of the algorithms at http://iv.slis.indiana.edu will be integrated, see menu.ini.http://iv.slis.indiana.edu

34. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Steps to integrate a new algorithm 1.Clean up the code and document it well. 2.Check if the IVC persistence layer satisfies your data storing and loading requirements (if not goto 5.2). 3.Implement the Plugin interface (visualization, java code) Two choices: (I) Build visualization window, return it to the IVC using getView method of the Plugin. (II) If your visualization uses a top-level GUI Container then start your visualization as a separate window and return null to the IVC. 4.Use java jar utility and archive your files including your plugin implementation and place it in the plugins folder. Put only java.class files in this jar. Put the other files at the same or lower level in the directory structure and make sure this is how you refer to your files within the code. Test your plugin to see that everything works. 5.Zip up or make a tar ball of all your files including non-java code. Now your algorithm is available to anyone who has the IVC. Anyone can download your zip file, unzip it in their plugins folder and the algorithm is immediately available.

43. Katy Börner: InfoVis CyberInfrastructure, InfoVis Conference 2004. Future Work This summer, more data modeling, data analysis and visualization algorithms will be integrated into the IVC. Hope many of you will contribute to the IVC via Sourceforge http://sourceforge.net/projects/ivc.http://sourceforge.net/projects/ivc A programmer-friendly Java API that allows researchers to pipeline data between analysis algorithms and visualization tools within and outside the IVC will be implemented. Algorithm documentation and the learning modules set will be updated/expanded. We plan to have demos/tutorials on the InfoVis CyberInfrastructure at the - InfoVis Conference 2004 in London, UK, July 14-16. - IEEE InfoVis Conference 2004 in Austin, Texas, Oct 10-12. - Visualization and Data Analysis Conf. 2005 in San Jose, CA, Jan 17-18.
