Action 2

ACTION 2:

Service architecture and implementation

Action 2 consists of four individual activities:

Activity 2.1: Design and implementation of knowledge based support for user description in both waste stream and solution provider domain.

Activity 2.2: Design and implementation of semantic web service platform to support symVIOTic matching between users.

Activity 2.3: Design and implementation of analysis, feedback and interface tools.

Activity 2.4: Design and implementation of semantic web operation and portal.

Activity 2.1 involves design and implementation of waste stream and solution provider knowledge models to support description of user semantic services. Effectively, ontology engineering is the standard and common means to build knowledge models. Initially, light weight ontology has been designed to capture knowledge in the domain of waste stream and solution provider technologies concerning industrial symbiosis, in particular type and composition to reflect classification provided in Activity 1.2. At the second stage, descriptive attributes, properties and restrictions on properties were added to reflect metrics defined in Activity 1.3, in particular geographical availability of waste and byproducts, environmental and economic properties and restrictions of processing technologies. Respective links to relevant and available datasets and datasets specified by the users are ensured through metadata descriptors (annotation properties).

During the Activity 2.2 a semantic web service platform was designed and implemented, to include:

  • Design and implementation of service description facility and concomitant repository to store all users’ descriptions;
  • Selection of an appropriate inference engine from a set of already available ones, adaptation for processing waste stream and solution provider knowledge models, ontologies, developed in Activity 3.1 with a view to automatically create users service descriptions under selected framework (OWL-S or WISMO) and its implementation;
  • Selection of an appropriate service matchmaker from a set of already available ones, adaptation for matching the services in the repository and ranking not only by their semantics, but also by their environmental and economic properties and its implementation. The actual weighting of the properties for ranking is determined by the user to reflect respective environmental/economic policy;
  • Design and implementation of web facility which enables implementation of regulatory requirements and practice, such as legal restriction on synergy or specifics requested by individual users, for instance geographical location, as specified in Activity 1.1.

Support tools have been implemented during activity 2.3 to further support establishing and monitoring the process of symbiosis. This includes infrastructure for data collection from all the users, as well as graphical presentation of metrics and symVIOTic parameters, geographical location of users, user feedback facility and tools (statistical) to measure the quality of the process.

Analysis, feedback and interface tools has been implemented during activity 2.3 to further support establishing and monitoring the process of symbiosis. This includes infrastructure for data collection from all the participants, as well as graphical presentation of metrics and symbiotic parameters, geographical location of users, user feedback facility and tools (statistical) to measure the quality of the process.

Activity 2.4 involves design and implementation of a semantically enriched web portal to enable users to register, to create personal semantic web service and to publish their existence on semantic web, all in a user friendly fashion. The particular effort has been made to overcome differences in using jargon as opposed to scientific language, both of them existing in practice. This is enabled by the proper design of domain knowledge models (in activity 2.1) and their use to guide the process of registration and hence service description.

The  results from the implementation of Action 2 are:

  • A verified waste stream and solution provider knowledge models, ontologies needed for the service operation in Action 3

Target: minimum 5 different waste streams and 10 different technologies included

  • Implemented inference engine and service matchmaker
  • Design and implementation of the system tools
  • Implemented semantic web service and web portal

Target: minimum one service implemented at VIOT beneficiary server.

Progress Indicators:

  • Timely waste stream and processing technology ontology design and implementation
  • Design and implementation of inference engine and service matchmaker
  • Design and implementation of all systems tools for monitoring
  • Design and implementation of semantic web service model, service repository and web portal.
