| Summary: | Ontology is a technology for conceptualizing specific domain knowledge, which can provide machine-readable definitions to the severed domain. Therefore, ontology can be utilized to enhance the performance of focused crawlers, by precisely defining the crawling boundary. In this paper, we will exhibit a conceptual framework of an ontology-based focused crawler serving in the domain of transport services. Here, a transport service ontology is designed for filtering non-relevant metadata, by means of logically linking the metadata with ontological concepts. In addition, we will provide the evaluation process in order to assess the power of ontology in the focused crawler. Conclusion and further works based on our current evaluation results will be made in the final section.
