Problems solved by technology

However, there are a large number of Mashup services registered in mainstream service warehouses, and most of the Mashup services only use natural language to describe services, lacking normative Web Services Description Language (WSDL) documents, which undoubtedly hinders service search. Increased difficulty of work

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] refer to figure 1 and figure 2 , a Mashup service feature representation method based on functional semantic association calculation, characterized in that the method comprises the following steps:

[0053] The first step is to preprocess all Mashup service data that requires feature representation;

[0054] The second step is to extract functional nouns based on the preprocessed Mashup service data;

[0055] Step 3: For the functional noun set FS of each Mashup service, perform semantic association calculation on the semantic weight of each functional noun;

[0056] The fourth step is based on the semantic weight calculation results of the third step, combined with the TF-IDF algorithm and the Word2Vec model, to represent the Mashup semantic feature vector, the process is as follows:

[0057] For each mashup service, based on the semantic weight calculatio...

Abstract

The invention discloses a Mashup service feature representation method based on functional semantic association calculation. The method comprises the following steps: 1, preprocessing all Mashup service data needing feature representation; 2, based on the preprocessed Mashup service data, performing a function noun extraction operation; 3, for the function noun set FS of each Mashup service, carrying out semantic association calculation on the semantic weight of each function noun; and 4, based on the semantic weight calculation result in the step 3, combining a TF-IDF algorithm and a Word2Vecmodel to express a Mashup semantic feature vector. According to the invention, the matching precision of Mashup services and the service search efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the field of Mashup service clustering, in particular to a Mashup service feature representation method based on functional semantic correlation calculation. Background technique [0002] In recent years, with the continuous development of information technologies such as big data, cloud computing, and mobile Internet, the business scenarios faced by Web services have become more diverse and complex. Traditional single-function services have been unable to meet the flexible and changeable user needs in reality. In this background, Mashup technology is considered to be a key way to solve this problem. Mashup technology constructs a brand-new web application—Mashup service by mixing and matching a variety of Web API services with different functions. This convenient and efficient development technology greatly improves the development efficiency of software developers for composite-level applications. It allows software develope...
