Achieving the interoperability of Internet of Things (IoT) platforms raises a key challenge, as most current IoT applications are vertically integrated within separate silos without horizontal communications. In response to this, we propose the Semantics Extractor, a framework for automatic extraction of semantic graphs from REST interfaces exposed by IoT platforms. Through an iterative process of...
The vision of the Internet of Things (IoT) promises the capability of connecting billions of devices, resources and things together. In the realisation of this vision, we are currently neglecting the interoperability between devices that is caused by a heterogeneous landscape of things and which leads to the proliferation of isolated islands of custom IoT solutions. A first step towards enabling some...
Web APIs provide interfaces for interaction among systems based on the existing infrastructure for hosting Web sites and applications. The REST architectural style is the most employed approach for building Web APIs. However, the flexibility provided by REST may result in implementations with low quality design, limited reuse and poor documentation. This paper describes a maturity model for classifying...
Support from development tools and infrastructure frameworks is crucial to increase the development of Web APIs that follow the REST architectural principle, leaving the software developer free to focus on the implementation of the business core of the application. This paper introduces a framework for semantic description of RESTful Web APIs, which is based on annotations added to the application...
PROMIS (Project Management Information exchange Services) is a research consortium with Fujitsu, IBM Japan, Hitachi, NEC, Nomura Research Institute, NTT DATA and Nanzan University. It aims at developing a new software engineering platform for managing SSN (Software Supply Network), an inter-organizational model of software development. This article reports on the background, goals, research challenges,...
This article proposes a new architectural principle for LISA (LInked Service Architecture) based on the Linked Data, ROA (Resource-Oriented Architecture), and meta-level service broker. LISA employs a two-layer architecture separating the concerns into meta-level of linking and base level of provisioning of services. A meta-level broker can dynamically coordinate services, and make the provisioning...
Despite significant research and development efforts, the vision of the Semantic Web yielding to a Web of Data has not yet become reality. Even though initiatives such as Linking Open Data gained traction recently, the Web of Data is still clearly outpaced by the growth of the traditional, document-based Web. Instead of releasing data in the form of RDF, many publishers choose to publish their data...
Expert Collaborative Filtering is an approach to recommender systems in which recommendations for users are derived from ratings coming from domain experts rather than peers. In this paper we present an implementation of this approach in the music domain. We show the applicability of the model in this setting, and show how it addresses many of the shortcomings in traditional Collaborative Filtering...
