Title: "UFO-S: A Core Reference Ontology for Services"
Speaker: João Paulo A. Almeida, Associate Professor, Computer Science Department, Federal University of Espírito Santo, Brazil
Abstract: In this talk, João Paulo A. Almeida will present UFO-S: A Core Reference Ontology for Services. UFO-S addresses the three basic phases of the service life-cycle, namely: (i) service offer (when a service is presented and made available to a target customer community), (ii) service negotiation (when providers and customers negotiate in order to establish an agreement), and (iii) service delivery (when actions are performed to fulfill a service agreement). The ontology accounts for service phenomena from the perspective of the social relations established and maintained by service participants. As a reference ontology, UFO-S is intended to assist humans in meaning negotiation and shared understanding. It is grounded in the Unified Foundational Ontology (UFO), from which it reuses foundational notions of objects, types, object properties, object relations, reified relational complexes (relators), events/processes, and further social concepts that specialize the more general notions and account for social reality.

Title: "ETSI Industry Specification Group for Context Information Management"
Speakers: Dr. Lindsay Frost, Chief Standardisation Engineer, NEC Laboratories Europe GmbH, ETSI Board Member, SF-SSCC Delegate, ISG CIM Chairman, NEC Labs Europe; and Ricardo Vitorino, Smart Cities R&I Manager at Ubiwhere and Vice-Chairman of the ISG CIM at ETSI
Abstract: The ETSI Industry Specification Group for Context Information Management has been working since early 2017 to create a flexible and relatively simple means to exchange information (data and metadata) between different systems and users: called NGSI-LD APIl. The initial target was Smart Cities, which is being expanded towards Smart Agri-Food topics. The API requires all data to reference its definitions of terms and properties and relationships i.e. the data ontology. The API itself has a minimalistic core ontology and facilitates referencing of many/most kinds of data ontologies (the approach uses Property Graphs so that besides properties also relationships are covered, and also properties of properties for e.g. annotating provenance). Much introductory material, including links to specification documents for the NGSI-LD and the information modelling specification, is available on our open area.

Title: "Common City Concepts: Results from the PolisGnosis Project"
Speakers: Professor Mark Fox, Associate Director, Research, School of Cities, is Distinguished Professor of Urban Systems Engineering and Professor of Industrial Engineering and Computer Science (Full biography
Abstract: Cities use a variety of metrics to evaluate and compare their performance.  With the introduction of ISO 37120, which contains over 100 indicators for measuring a city’s quality of life and sustainability, it is possible to consistently measure and compare cities.  The goal of the PolisGnosis project is to enable the performance of longitudinal analysis (i.e., how and why a city’s indicators change over time) and transversal analysis (i.e., how and why cities differ from each other), in order to discover the root causes of differences. A major focus of the project has been the development of ontologies of city knowledge  that can be used to represent indicator definitions and the data used to derive them. Over the last 7 years ontologies have been created to created for many of the ISO 37120 themes, including Environment, Health, Public Safety, Shelter, and Transportation (visit This presentation will review the concepts that are shared across the themes.
