  1. C r o s sp o i n tCollaboration Services for the 21st Century Patrick Gabriel (James Madison University) Joel Coffman (CS Graduate Student, University of Virginia) NSF Research Experience for Undergraduates, University of Virginia

  2. What is Crosspoint’s Vision? • Crosspoint is a web-based collaboration service which is intended to enhance interaction among problem holders. • End users issue a Request for Information (RFI) and identify the nature of the solution needed. • An analyst picks an RFI for review, and then works to • understand the problem, • sharpen the question, • and clarify the end user’s goals.

  3. Crosspoint’s Vision • The analyst uses Crosspoint to locate Subject Matter Experts (SMEs) whose skill set and availability match the requirements of the problem being addressed. • Crisis Action Teams (CATs) for short-term problems • Communities of Interest (COIs) for long-term problems

  4. Crosspoint’s Vision • The CAT/COI collaboration team members: • collectively develop an action strategy, • locate and collect relevant information and data assets, • perform analyses, • and produce information products and visualizations relevant to the desired end-state. • The analyst delivers the collaboration team’s response to the problem holder.

  5. Crosspoint’s Vision • Over time, each analyst and SME acquires an electronic reputation regarding the utility of their work product. • Analysts provide feedback for the SMEs • End users provide feedback for the analysts

  6. Why is Crosspoint Needed? • Today’s collaboration tools assume that the user already knows the identities of those with whom he or she wishes to collaborate. • In contrast, with Crosspoint, problems can be described from the problem holder’s perspective, and the characteristics of the desired outcome can be identified. • Crosspoint is collaborator-focused, in that the analyst uses a query service to locate SMEs with relevant skills. • SME profiles • Crosspoint is implemented using web services • Avoids adding another application to run and manage • Users can integrate Crosspoint into their existing and future projects without undergoing a complete redesign.

  7. Bridging the Gap

  8. What are Crosspoint’s Capabilities? • To achieve its vision, Crosspoint must support the following capabilities: • user-friendly creation and management of RFIs • interaction between the analyst and the RFI’s author • collaboration among the CAT/COI team members • definable search queries for the SME profile database • customizable priorities and preferences for search queries • delivery of requested information end-state to the end user

  9. Technology • Crosspoint utilizes three main technologies to accomplish its goal: • Apache HTTP Server 2.2.4 • PHP 5.2.3 • PostgreSQL 8.2. • PostgreSQL 8.2.4 was implemented for the following reasons: • It is faster with a large feature set • Provides excellent data integrity • Is stable and reliable

  10. Crosspoint Demo • Login • User Interface • Profiles • End User • Analyst • Subject Matter Expert • RFIs • Search • Results

  11. Future Work • Formation of CATs/COIs • Search algorithm development (currently a boolean search) • Must be specific for a relational database (google operates on text, not tables) • Weighted search • Electronic reputation (feedback) • User defined tags (like del.icio.us)
