Notes de l'éditeur

  • What do we care or matter ?

    Deal with the complexity.
    Mean to validate the data, all possible aspects.
    Prevent the launch of lengthy computations when the data is incomplete or incorrect.
    A simple way to create the necessary knowledge to validate the data .. in a modular form so that it can be reuse and recomposed for different applications.
    Report any missing or invalid content with recommendations for quick identification and correction.
    Provide justification as to why validation fail

    Why did we do this work and what is different from what is existing.
    Rule checking is most famous for firewall to secure communications
    Traditional rule systems are usually relatively linear (one line per rule), following a specifc style (XML), with limited validation capabilities and lengthy, hard to read or interpret rule listing.

    We tried to build a complex yet easy to use experience for both the users and the subject-matter expert hat create and maintain the validation knowledge base.
  • Initial problem targeted: Lightweighting.
    But the system can also achieve a practical, performant and good looking geometry.
    The system do so through intelligent interactions and a back and forth with the user to identify the right design for the desired purpose.
  • Lightweight data unification service
    Convert data from multiple source types
    Schema based
    Works using content maps connected by domain ontologies
    Easily deployable with dedicated user interface for mapping creation
  • Show application diversity:
    Netfabb – Additive manufacturing
    Moldflow – Injection molding
    Revit – Architecture
    FeatureCAM – CNC tool path
  • Customers are attached to local desktop deployments on their own machine.
    Migration is in stage:
    Migrate data to facilitate live and regular updates
    Create bridges to Cloud compute capabilities through web based equivalents

  • Making the application to talk the same language would require massive refactoring and entire recoding.
  • Thus the idea to introduce an ontology service as a middleman
  • beneficial to the experience
    advantageous
  • Unification is really plan B as it is time consuming, plan A is to hove all related data in the same media if possible.
    Does not mean all data is one uber place but an intelligent domain separation with an effort to avoid duplications that would require unifications.
  • Lightweight service for validation and recommendation
    JSON based
    Rich set of validation techniques
    with Descriptive Logic and Code Logic
    Well-structured and easy to use validation knowledge base
    by combining Domain ontologies and Application models
    Easily deployable and scalable
  • Stream reasoning strategies
  • Roughly
  • Whether it is for supporting existing applications or creating new intelligent ones, Semantic Web has an incredibly important place, directly inside core applications or within derivative services to structure coordinate and reason over data. In the future, it will certainly be an essential component to build intelligence along with algorithms in Machine learning and technologies sch as Quantum computing.

    Connected to other digital storage -> Capture human knowledge and expertise

    As we have neurons in our brain and Cloud have service architecture. The answer is a mix but both machines and humans have limits.

    Personal opinion mostly based on how manageable the data (structure, lifecycle and monitoring) and who is supposed to manage the data (human, machine).

    Machine = allow larger blobs but beware that without control can become overly time consuming.
    Human = allow only moderate blobs because error prone, but can be protected by validation rules and human reviews.

    Ultimately, data like code beyond certain sizes and increased complexity need restructuring whether managed by machines or humans.
