Abstract

The invention belongs to the technical field of Internet data acquisition and application, and provides a service tag extension method in a big data environment. The service tag extension method includes the steps that the content of actual service is obtained, and a tag representing the service is extracted out; the tag is retrieved through a search engine to obtain an initial set of key words and webpage addresses (URLs) related to the tag; all the keywords and the URLs in the initial set are calculated according to K center distance, naive Bayes and pointwise mutual information algorithms to obtain weights; whether the weights meet a certain threshold value or not and are added into a result set of the tag or not is judged; whether the scale of the result set is larger than or equal to a scaled threshold value is judged. The service tag extension method has the advantages that a servicer can extend the service tag and the keywords and the URLs belonging to the tag conveniently through simple operation, the production efficiency is greatly improved, and requirements of development of various services are met.
