Data resource semantic support method research based on meta-data annotation

The concept of the cloud is no longer limited to providing remote hardware or platform support with the development of cloud computing technology. Instead, it encapsulates all aspects of the content in computer field into service invoked by others. As an important part of software, data resource has become core services to the cloud platform in areas such as collaborative manufacturing and collaborative service. Since these data are complex in structure, strongly independent but related to each other, it is necessary to annotate these data to improve their operability and make them able to be utilized more widely. This paper wants to design an annotation method based on word segmentation and semantics replacement aimed at metadata according to the characteristics of the meta-data itself. As a result, these data resource can then be understood by computers and further support later studies such as data fusion and semantic retrieval.
