The aim of this workshop is to bring together researchers, practitioners, stakeholders and users of the Open Web, meant as a huge and easily accessible source of data, information and services. The focus of the workshop will be on practical engineering approaches (i) to design and develop open data and services on the Web (i.e., the Web seen as an output media of an organization's information system), on the one side, and (ii) to design and develop open source intelligence and retrieval techniques on the other side (i.e., the Web seen as input media of an organization's information system). We seek for papers describing practical engineering approaches, case studies, lessons learned, etc.

Title: Introducing Ontology-based Open Data Publishing
Abstract:
The recent peak in interest in Open Data from both public and private organizations has led to significant efforts in defining guidelines and methodologies for Open Data management and publication. Nevertheless, although a number of guides and best practices introduce data formats, data licenses, and architectures for publishing Open Data, a formal and comprehensive methodology supporting an organization in deciding which data to publish and how to publish it at a high quality is still missing. One of the reasons of this lack of formal methods is that the problem of Open Data Publishing is strictly related to the problem of managing the data within an organization. In this talk we will show how the novel paradigm of Ontology-Based Data Management (OBDM) can provide the principles and the techniques for addressing this challenge. In OBDM, the usual global schema of traditional data integration systems is replaced by the conceptual model of the application domain, expressed through a logic-based ontology language. Suitable mappings are used to link the concepts in the ontology to the data at the sources, so that services expressed over the ontology can be translated into low-level services over the data. After a formal presentation of the OBDM framework, we will then go on to show how the investment of developing an ontology and mapping it to the relevant data source will produce the know-how for an organization to publish and maintain high quality Open Data, annotated with relevant semantic metadata.
Short Bio:
Domenico Fabio Savo is a research associate at DIAG, the Department of Computer, Control, and Management Engineering Antonio Ruberti at Sapienza University of Rome, and Co-Founder and leading member of the OBDA Systems's research and project development team. He received his Ph.D. in 2013 from Sapienza University of Rome, and was a fixed-term assistant professor at Sapienza University of Rome from March 2014 to February 2017. His research interests focus on the application of semantic technologies for information and data management. He studies the application of reasoning techniques over ontologies for data management: Ontology-based Data Management (OBDM); Knowledge Representation, Ontology Engineering, and Semantic Web. He has participated in several projects in collaboration with private companies and public administration bureaus with the aim of applying semantic technologies to real-world scenarios. In 2017 he (co)founded the OBDA Systems, an innovation startup of Sapienza University, which proposes state-of-the-art solutions based on the most recent breakthroughs in the field of semantic technologies. Domenico Fabio Savo regularly publishes the results of his research, and regularly serves as reviewer for conference and journals in the areas of his interest.
The workshop is held in conjunction with 17th International Conference on Web Engineering (ICWE 2017). Please refer to the conference main page for information about registration.
The main goal of the workshop is to give to the research and practicing community operating in open Web technology an opportunity to share ideas and confront each other about the challenges involved in exposing data on the Web through open services, on the one side, and to acquire information from the open Web, on the other side. Topics include (but are not limited to):
Reference architectures for the open Web
Design approaches for open Web integration architectures
Integration strategies for the open Web
Caching methodologies
Access throttling
Data refresh strategies
Integration conceptual schemas for horizontal and vertical markets
Support for streaming and big data in open Web technologies
Monetization strategies for the open Web: the business behind the open Web
Existing open Web initiatives and ecosystems
Comparison between open Web approaches and (semantic) open data approaches
