The Research Of Sensor Ontology Modeling Based On FCA And LSA

The purpose of this paper uses domain ontology construction method based on FCA and LSA to model the sensor domain ontology, aiming at solving to these problems such as no unified standard to guide the construction of ontology in the process of building ontology, the unclear hierarchy structure of constructed ontology and lack of updating for the constructed ontology.This paper analyzes the existing ontology construction method based on FAC by summarizing these advantages and disadvantages and standardizing them. Then,we summarize five steps of domain ontology construction method based on FCA.On this basis,we use related technology of LSA to update the domain ontology by summarizing the four steps of updating domain ontology based on LSA. We standardize the modeling method of domain ontology and apply the standardized method to model the sensor domain ontology to solve the problem of sharing and reusing of the sensor data.The innovation point of this paper is that we apply ontology modeling method based on FCA and LSA to Semantic Sensor Web to construct the sensor ontology,solving some existing problems in process of sensor ontology constructionThe research result of this paper proposes a new kind of ontology construction method based on FCA and LSA. Firstly, we propose the five steps of ontology construction based on FCA. Then, we propose the four steps of updating domain ontology.The research achievements of this paper can be used to guide the construction of small and medium-sized domain ontology and also can be play a good role in the relevant scientific fields.
