Research on Ontology Reasoning Based on SWRL

With the emergence of semantic web, ontology becomes a hotspot of computer science.After introducing the conceptions and features of ontology, OWL and SWRL, The paper uses the visual descriptors to describe the features of image according to standard of MPEG-7, adopts ontology to build the semantic features of image, and uses OWL to describe these visual descriptors.Then the paper imports SWRL to image emotion recognition, uses SWRL to construct the inference rules, and executes the inference rules to find the implied information.The conclusion is to make computer have the ability of image emotion recognition by using the information of image ontology and inference rules.
