Automatic Extraction of Fuzzy Domain Ontology Concepts
演讲摘要:
Although the semantic web is getting popular, such as Google YouTube, the engineering of the knowledge construct using relation tagging of concepts is very time consuming and expensive involving a large amount of human resources. For example, the IMDB movie management site, and Wikipedia website, they both want to discover the knowledge and allow their clients to search for the information across the knowledge base. Nevertheless, to achieve this goal, they must face a big challenge which is how to tag and link up those concepts. It appears that human tagging is not a feasible way to build up the solution space, and it becomes the bottleneck of knowledge acquisition. We are dealing with this bottleneck, which is also a classical knowledge engineering problem.
This talk presents an Automatic Ontology Concepts Extractor (AOCE) for ontology construction. The AOCE extracts concept knowledge from a fuzzy domain of movie articles involving imprecise or vague information. The system development and formulation of algorithms for the extraction process will be discussed.
Experimental results are promising that the system can reduce human efforts for extracting concepts and knowledge from similar articles in a specific domain. The proposed methodology demonstrates the potentials of automatic ontology construction and creation, which give a positive step toward resolving the bottleneck problem in knowledge acquisition.
