OntoWEDSS: an ontology-underpinned decision-support system for wastewater management
msra
摘要
This paper characterizes part of an interdisciplinary research on articial intelligence techniques ap- plied to environmental decision-support systems. The architecture's design of OntoWEDSS, a decision support system for wastewater management, is presented. This system augments classic rule-based reasoning and case- based reasoning with a domain ontology. The integration of the newly created WaWO ontology provides a more e xible management capability to OntoWEDSS. The construction of the decision support system is based on a specic case study but the system is also of general interest, given that its ontology-underpinned architecture can be applied to any wastewater treatment plant and, at an appropriate level of abstraction, to other environ- mental domains. The OntoWEDSS system helps improve the diagnosis of faulty states of a treatment plant, it provides support for wastewater-related complex problem-solving, and it facilitates knowledge modeling and reuse by means of the WaWO ontology. In particular, the following issues are dealt with: (1) the improve- ment of the modeling of information about wastewater treatment processes and the clarication of a part of the existing terminological confusion in the domain, (2) the incorporation of ontology-modeled microbiologic knowledge related to the treatment process into the reasoning process and (3) the creation of a decision support system with three layers (perception, diagnosis and decision support) which combines knowledge through a novel integration between KBSs and ontologies, thus providing better results.
