Data from various sources are in heterogeneous underlying formats. Combining and extracting data from all such sources will require the user to generate mappings between the different formats which vary on a case by case basis. The solution proposed is a knowledge-based approach to solve the problem of data extraction from different source formats: Build ontologies from source files, find mappings between ontologies, use reasoners to extract data, and convert ontologies to desired formats. There are several ontological tools in the market for converting, mapping and reasoning ontologies. Rather than re-inventing the wheel, the solution proposed is to develop a workbench of all the existing tools in the ontological domain and those that may emerge. This is achieved by an extensible Eclipse plugin based architecture called Knowledge-based Data Extraction (KDE). In addition to the architectural aspects of KDE, this thesis makes the following contributions: a taxonomy of terms used in the ontology domain, identification of the capabilities missing in existing ontological tools, and a scenario-based comparison of two ontology mapping algorithms used in the implementation of the architecture.
