A Survey of Approaches to Web Service Discovery in Service-Oriented Architectures

Abstract

Discovering services acquires importance as Service-Oriented Computing (SOC) becomes an adopted paradigm. SOC’s most popular materializations, namely Web Services technologies, have different challenges related to service discovery and, in turn, many approaches have been proposed. As these approaches are different, one solution may be better than another according to certain requirements. In consequence, choosing a service discovery system is a hard task. To alleviate this task, this paper proposes eight criteria, based on the requirements for discovering services within common service-oriented environments, allowing the characterization of discovery systems. These criteria cover functional and non-functional aspects of approaches to service discovery. The results of the characterization of 22 contemporary approaches and potential research directions for the area are also shown.

A tool to improve code‐first Web services discoverability through text mining techniques

“…Indeed, there are many discovery registries exploiting the Vector Space Model (see for a pioneer work in this line). However, one of the main differences between the registry used in the experiments and similar alternatives is that the former uses a two‐step matching process that greatly reduces discovery time and it is suitable for distributed environments such as WANs or the Internet, where the number of services is large.…”

“…Previous to Baghat et al , different authors have detected this issue in Web services. To solve this issue, different researchers have proposed Web service registries. Basically, this kind of tools can be divided into two types : registries for regular Web services and registries for Semantic Web Services.…”

The latter are Web services that have been annotated with semantic information from an ontology.…”

HyOASAM: A Hybrid Open API Selection Approach for Mashup Development

“…Open APIs discovery is the efficient and accurate retrieval of a set of open APIs or services that achieve the needs of users from a service database based on the demand statements entered by users [18]. Generally, the discovery approaches can be categorized into the following two main classes.…”

An approach to improve code-first web services discoverability at development time

“…This registry exploits relevant information contained in WSDL documents by combining text-mining and machine learning techniques to remove redundant plus non-relevant data and build a vectorial representation of each service, respectively. This is a classical model borrowed from the Information Retrieval area, known as Vector Space Model [5], which is widely employed for discovering services, as reported in a recent survey of approaches to discover services [6]. With this model, documents are seen as collection of terms, whereas each dimension of the space corresponds to a separate term, thus documents having similar contents are represented as vectors located near in the space.…”
