Inria Rhône-AlpesEMGnet meeting - December 98 1 A Platform for EMG Studies Danielle Ziébelin, Martine Maume and Philippe Genoud INRIA Rhône-Alpes Projet Sherpa

Inria Rhône-AlpesEMGnet meeting - December 98 2 Goals of the EMGnet Project share the different resources of the EMGnet nodes ­software ­specialized equipment... exchange data that require analysis enhance knowledge and profit from it

Inria Rhône-AlpesEMGnet meeting - December 98 3 Difficulties each node should have access to the competence of the other nodes but... complex software libraries / modules heterogeneous computer environments physicians are not programmers

Inria Rhône-AlpesEMGnet meeting - December 98 4 The JACOMO Platform JAva & COmponents for electroMyOgraphy a common platform for the different partners that allows them: - to integrate their own software - to access software of the other partners

Inria Rhône-AlpesEMGnet meeting - December 98 5 JACOMO’s Features use of software components to encapsulate data processing ability to distribute processing visual programming interface aid to the users through the use of a knowledge base JAVA language: the glue to assemble different parts of the platform

Inria Rhône-AlpesEMGnet meeting - December 98 6 Software Components modules to be integrated in the environment modules with different levels of granularity related components to link the modules (filters, choice, loop, …) creation of « scripts » (chains of components)

Inria Rhône-AlpesEMGnet meeting - December 98 7 Visual Programming GUI to dynamically ­load ­configure ­connect ­execute components

Inria Rhône-AlpesEMGnet meeting - December 98 8 Knowledge Based Supervision Knowledge Based Problem Solving System The user submits a problem to be solved The system helps him/her in ­selecting the right components ­interacting with the components (parameters) ­linking the components

Inria Rhône-AlpesEMGnet meeting - December 98 9 Types of Knowledge Methodological (strategies of resolution) ­decomposition of a problem to several subproblems (tasks) ­association of one or more components with each elementary task ­assembling the components to solve a higher level problem Methodological KB Component library

Inria Rhône-AlpesEMGnet meeting - December Types of Knowledge Methodological Descriptive ­functionality of the components ­nature of the information used by the tasks input, output Methodological KB Components library KB related to the EMG domain

Inria Rhône-AlpesEMGnet meeting - December Distribution Domain (descriptive) knowledge ­common knowledge shared by all the partners Components and the operative knowledge associated with them ­developed and maintained locally under responsibility of each EMGnet node ­accessible by the other nodes through the network

Inria Rhône-AlpesEMGnet meeting - December Distribution (cont.) A task can be published to allow its use from other sites A distant task used in a problem solving strategy is seen as a terminal task

Inria Rhône-AlpesEMGnet meeting - December Distribution (cont.) When a distant task is invoked ­the resolution graph is downloaded ­the resolution process continues until elementary tasks are obtained

Inria Rhône-AlpesEMGnet meeting - December Distribution Execution of a distant component ­Download of the component and then its local execution ­Remote execution Data Results

Inria Rhône-AlpesEMGnet meeting - December How far we are ? INRIA: has long-term and valuable experience in program supervision based on tasks object-based knowledge representations + is currently focusing on technology components and building the EMG knowledge base + has to develop the distributed environment (RMI, CORBA, etc.) JACOMO

Inria Rhône-AlpesEMGnet meeting - December Contribution of INRIA to the Project creation of a knowledge base of the EMG concepts specification and development of the visual distributed environment based on components implementation of a component to record medical cases
