Abstract

The invention provides a Web service package recommendation method and system based on combined feature extraction. The method comprises: a step 1, performing semantic feature extraction; a step 2, according to the extracted semantic features, training a deep neural network and extracting combined features, and predicting the probability whether Web service pairs can be used for Mashup to be developed at the same time or not; and a step 3, recommending the Web service package according to the probability adopted by the Mashup to be developed. According to the method, the comprehensive functionformed by combining Web services can be extracted, so that a group of complementary Web services can be recommended to developers, and the Mashup requirements are completely covered.

Description

technical field [0001] The invention relates to the technical field of networked Web service retrieval, in particular to a method and system for recommending Web service packages based on combined feature extraction. Background technique [0002] Web services are an important part of modern information systems, and the number of Web services is increasing exponentially on the Web. Many businesses facilitate their business by providing web services, and developers rely on web services to build their applications. Various tools have been developed to help developers or non-IT professionals consume web services. Among them, Mashup is becoming a commonly used method, through which multiple Web services can be combined to provide more comprehensive functions. [0003] When designing a mashup, we must search and select appropriate web services. Due to the huge number of web services available on the web, finding the web services we need is a challenging task. Therefore, develo...
