The Problem

The Problem


Services (Tool) Interoperability


Common Services

Traceability
Quality
Naming
...


Open Services for Lifecycle Collaboration (oslc)


http://upload.wikimedia.org/wikipedia/en/7/7e/OSLC_diagram.png

Specifications 

3 main challenges and key-enablers


  1. Controlled vocabulary and ontology 
  2. X Breakdown Structures (e.g. PBS) 
  3. Services to manage domain knowledge


Some common Services...

  • Naming 
  • Index & Retrieval 
  • Traceability
  • Quality
  • ...

From natural language

To   requirements,  Models, etc.


OSLC-BASED SERVICES



and more...index and retrieve anything

(math formulas, electrical networks, tables, etc.)

On-going work

  • Requirements are  the key-entities  for the development of critical systems
    • Requirement as a basic unit of specification
    • Link requirements to models 
    • Quality is a MUST
    • Verification and Validation
    • Model-driven Requirements Engineering ( MDRE )
  • Re-use information and data to create a real collaborative environment
  • OSLC to ensure compatibility among tools
    • Linked Data in a controlled environment...


The Proposal...


Quality Metrics for Graph-based structures


Community detection?
Traceability?
....
Case Studies: Quality in SN and SE?

Approach



...in other words...

  • Specify the Quality Metrics
  • Design the algorithms for implementing them
  • Implement an infrastructure
  • Design & create a testbed
    • Social Network Analysis
    • Systems Engineering Quality

Similar approach...

Plan & Schedule

  • 6 full weeks in Wrocklaw
  • Work in Madrid
  • 1-2 weeks of integration and validation in Wrocklaw (to define)


Expected Outcomes

  • A set of quality metrics for graph analysis
  • A test-bed of two scenarios: SN and SE
    • Publish data and workflow? (OpenScience)
  • A public demonstrator
  • Research
    • Publications

Other collaborations...

  • Find a common technology and make a kind of "hands-on session"
    • Share knowledge & experience
    • 1 or 1/2 day
  • Prepare some type of event:
    • Some special issue proposal
    • Some workshop
    • ...
  • Make publications:
    • Journal and Conference Papers
  • Project proposals:
    • H2020
    • Eurostars
    • ...


...for your attention!
