Knowledge Representation Model for Crime Analysis

The knowledge representation model is a particular way in representing knowledge by using the knowledge and reasoning mechanism. Ontology is a kind of knowledge representation model that represents knowledge as a set of concepts within a domain and the relationship between these concepts. It is important to solve the problem of large amount of data in the crime investigation domain which is not well defined in a proper relation. The problems exist currently are how to develop an ontology model to represent the crime investigation information and how to make good use of the information represented by the model. These problems could be solved by developing an ontological-based case matching model, named CrimeAnalysis as a study prototype. In this study, an ontology model is developed using the selected semantic modelling tool, named TopBraid Composer Standard Edition in order to represent the crime information with the well-defined classes and relationships. This would help to save the investigation officer's effort in aiming and targeting the possible suspect within the shortest time interval.
