A likelihood-free Bayesian derivation method for service variants

Static Analysis for Improved Modularity of Procedural Web Application Programming Interfaces

“…In our algorithm, this search process is captured by function SemanticMatch(p, R) (line 5) which either returns a business entity that semantically matches p or an empty element (null) when no match can be found. Next, if a matching entity e is retrieved, the mapping between e and the corresponding parameter p is recorded (line 11), and all the parameters p nested in p are mapped to the attributes of e (lines [12][13][14]. Mapping a parameter to an attribute is captured by function ConvertToAttr(p ) (line 13).…”

“…The technique exploits close proximity of parameters in each operation to determine the most likely next parameter to find for a subset based on a previous parameter probabilistic tree search. We herein give a short introduction to this service variant analysis technique proposed in our previous publication [14], where readers interested in the technique can find more relevant details. Figure 4 depicts an overview of our service variant analysis technique (using an abstract example).…”

“…The research presented in this paper draws upon and extending the techniques developed from our previous contributions [12]- [14]. An earlier version of our method for extracting business entities from a service interface specification was proposed in [12], and our initial findings in deriving the potential temporal order of operations that may be carried out by different business entities was reported in [13].…”

“…An earlier version of our method for extracting business entities from a service interface specification was proposed in [12], and our initial findings in deriving the potential temporal order of operations that may be carried out by different business entities was reported in [13]. In [14], we presented a service variant analysis technique which can be used to compute different ways of invoking a service based on the service's business entity model, and no further extension is made to this technique in our current study. However, given that this technique is an important part of the overall systematic approach that we propose for static analysis of Web APIs, a short introduction to the technique published in [14] is included in the paper.…”

Furthermore, having a complete proposal of our systematic approach allows us to present an overall tool implementation of the approach and its application to several services that are widely deployed in practice.…”
