A semantic and agent-based approach to support information retrieval, interoperability and multi-lateral viewpoints for heterogeneous environmental databases
PhDData stored in individual autonomous databases often needs to be combined and
interrelated. For example, in the Inland Water (IW) environment monitoring domain,
the spatial and temporal variation of measurements of different water quality indicators
stored in different databases are of interest. Data from multiple data sources is more
complex to combine when there is a lack of metadata in a computation forin and when
the syntax and semantics of the stored data models are heterogeneous. The main types
of information retrieval (IR) requirements are query transparency and data
harmonisation for data interoperability and support for multiple user views. A
combined Semantic Web based and Agent based distributed system framework has
been developed to support the above IR requirements. It has been implemented using
the Jena ontology and JADE agent toolkits. The semantic part supports the
interoperability of autonomous data sources by merging their intensional data, using a
Global-As-View or GAV approach, into a global semantic model, represented in
DAML+OIL and in OWL. This is used to mediate between different local database
views. The agent part provides the semantic services to import, align and parse
semantic metadata instances, to support data mediation and to reason about data
mappings during alignment. The framework has applied to support information
retrieval, interoperability and multi-lateral viewpoints for four European environmental
agency databases.
An extended GAV approach has been developed and applied to handle queries that can
be reformulated over multiple user views of the stored data. This allows users to
retrieve data in a conceptualisation that is better suited to them rather than to have to
understand the entire detailed global view conceptualisation. User viewpoints are
derived from the global ontology or existing viewpoints of it. This has the advantage
that it reduces the number of potential conceptualisations and their associated
mappings to be more computationally manageable. Whereas an ad hoc framework
based upon conventional distributed programming language and a rule framework
could be used to support user views and adaptation to user views, a more formal
framework has the benefit in that it can support reasoning about the consistency,
equivalence, containment and conflict resolution when traversing data models. A
preliminary formulation of the formal model has been undertaken and is based upon
extending a Datalog type algebra with hierarchical, attribute and instance value
operators. These operators can be applied to support compositional mapping and
consistency checking of data views. The multiple viewpoint system was implemented
as a Java-based application consisting of two sub-systems, one for viewpoint
adaptation and management, the other for query processing and query result
adjustment

Critical thinking, problem solving : a unified framework for teaching a process approach.
This dissertation presents a unified framework to teach critical thinking and problem solving in a sixth grade computer classroom. In the context of this framework, problem solving is viewed as a critical thinking skill that also incorporates application of other critical thinking skills. Through a review of literature of critical thinking, problem solving, writing, Logo, simulations, and other related areas of study, we derive instructional principles important to consider when formulating a pedagogy to teach critical thinking/problem solving in a 6th grade computer classroom. We then present a rationale for a unified framework to teach critical thinking/problem solving and describe the said framework, titled, TACTICS (Tools ((to)) Assimilate Critical Thinking in Classroom Subjects). A process approach is advocated that includes an emphasis on the development of metacognition and an inquisitive spirit, the application of a general problem solving approach, and the use of specific heuristics. Through conscious use of critical thinking skills when applying problem solving strategies, students can learn to strengthen critical thinking and problem solving skills and come to see how the same general skills are used in a variety of circumstances. Eight instructional principles are suggested to teach critical thinking skills and to promote their generalization to other subject areas. These are supported by four problem solving tools designed to aid students in connecting their problem solving experiences in one area to their work in other subject areas. These tools are: Polya Four-Step General Problem Solving Approach, The Heuristic Bank, Student and Teacher-Made Reference Manuals and Students\u27 Journals. A curriculum resource book is included that demonstrates how the use of the TACTICS model can build critical thinking and problem solving skills when studying Logo, when writing or when using a simulation. Included are examples of curriculum unit and instructions for teachers to design their own curriculum units in their subject areas
