  20. Overview Brief Description of Teams Features and technical info Flowchart Process Screenshots of Usage 4/27/2011

  21. Instant Messaging

  22. Instant Messaging Team • Deployment of Openfire Server to implement XMPP protocol • MYSQL database to synchronize data with server • Chat client of choice: Spark(Windows and Linux), Adium(Mac) 4/27/2011

  23. Features and Technical Info • Openfire is a java based server implementation • XMPP protocol is open sourced and secure • Future improvements on server capabilities possible through plugins • Setup relies on a dual database configuration • Automatic user synchronization with ISO database 4/27/2011

  33. Isolation Layer Team Phase 3 Kendra Garwin Andrew Yi Skanda Mohan David Wang Skanda Mohan 1/24/11

  34. Overview What is Iso-Layer? The layer that isolates the database from other modules. Incorporated later after being recommended by Eric Rose. Reason:  Better modularity. Hence, better structure. 4/27/2011

  35. Composition Statistics: Packages and their handlers:     10 classes, 85 packages, avg ~ 50 SLOC/package External Packages Programs:      Dispatcher, Commands class, Diagnostic UI etc. Connecting to other modules:     External Applications, IOV, Infrastructure 4/27/2011

  36. Class Package Analysis Class Class, Group, User and Expertise Class Class Add, Remove, Files, Groups etc File Class Create, Destroy, Get, Info Friends Class Accept, Add, Ignore, List etc. General Class File, Link, Meeting, Post etc Group Class Add, Remove, File, Info etc. Meeting Class Add, Create, Date/time, File etc User Class Connect, Disconnect, Expert, Get Status Web Class Create, Destroy, Info Whiteboard Class File-path, Meeting, Users Composition 4/27/2011

  37. Working (Request) Iso Layer Dispatcher XML command Request XML command BLACK BOX USER Package XML command parameters Command Handler Data Base SQL command request 4/27/2011

  38. Working (Response) Iso Layer Dispatcher XML command Response XML command BLACK BOX USER Package XML command parameters Command Handler Data Base SQL command  Response 4/27/2011

  39. Testing A diagnostic GUI provided (with major modifications).  4/27/2011

  40. Database and Content Analysis Phase 3 Rohith Salim Jason Lei Steve Luminais 1/24/11

  41. Interaction Architecture 4/27/2011

  42. What is LingPipe • A toolkit for processing text using computational linguistics • Used to do tasks like • Find names of people, organizations etc in news • Automatically classify Twitter results into categories (Topics) • Annotating Databases of Information 4/27/2011

  43. Input to Output • Fed it three documents regarding Sensors • Topics Generated • Sensors, Voltage etc. • Generated through Linear Discriminant Analysis Algorithm • Clustering of words • Conclusion • Need a larger sample set 4/27/2011

  44. How we use it • Use LingPipe on existing Database to create topics from the documents and posts uploaded • Create a People-Web whereby different people are linked together if they have common expertise 4/27/2011

  45. What is BirdEye • Open source Information Visualization and Visual Analytics library for Adobe Flex • Community Project • Enables users to create multi-dimensional data visualization for analysis and presentation of information 4/27/2011

  46. How we use it • Represent the data extracted by LingPipe in a visually appealing manner 4/27/2011

  47. Overall Design • Isolation layer gets information from database • Sends Information as an XML file to LingPipe • LingPipe extracts the meaningful words(topics) out of these words • BirdEye then uses this information to create a visual, interactable representation 4/27/2011
