Are listed on W3C’s wiki: RDF programming environment for 14+ languages, including C, C++, Python, Java, Javascript, Ruby, PHP,… (no Cobol or Ada yet ) 13+ Triple Stores, ie, database systems to store datasets 16+ general development tools (specialized editors, application builders, …) etc Ivan Herman, W3C RDF(S), tools (cont.) Note the large number of large corporations among the tool developers: Adobe, IBM, Software AG, Oracle, HP, Northrop Grumman, … …but the small companies and independent developers also play a major role!

Anybody can start developing RDF-based applications today Ivan Herman, W3C RDF(S), tools (cont.)

  • Enhancing JSON to RDF Data Conversion with Entity Type Recognition
    Enhancing JSON to RDF Data Conversion with Entity Type Recognition Fellipe Freire, Crishane Freire and Damires Souza Academic Unit of Informatics, Federal Institute of Education, Science and Technology of Paraiba, João Pessoa, Brazil Keywords: RDF Data Conversion, Entity Type Recognition, Semi-Structured Data, JSON Documents, Semantics Usage. Abstract: Nowadays, many Web data sources and APIs make their data available on the Web in semi-structured formats such as JSON. However, JSON data cannot be directly used in the Web of data, where principles such as URIs and semantically named links are essential. Thus it is necessary to convert JSON data into RDF data. To this end, we have to consider semantics in order to provide data reference according to domain vocabularies. To help matters, we present an approach which identifies JSON metadata, aligns them with domain vocabulary terms and converts data into RDF. In addition, along with the data conversion process, we provide the identification of the semantically most appropriate entity types to the JSON objects. We present the definitions underlying our approach and results obtained with the evaluation. 1 INTRODUCTION principles of this work is using semantics provided by the knowledge domain of the data to enhance The Web has evolved into an interactive information their conversion to RDF data. To this end, we use network, allowing users and applications to share recommended open vocabularies which are data on a massive scale. To help matters, the Linked composed by a set of terms, i.e., classes and Data principles define a set of practices for properties useful to describe specific types of things publishing structured data on the Web aiming to (LOV Documentation, 2016).

  • Linked Data Schemata: Fixing Unsound Foundations
    Linked data schemata: fixing unsound foundations. Kevin Feeney, Gavin Mendel Gleason, Rob Brennan Knowledge and Data Engineering Group & ADAPT Centre, School of Computer Science & Statistics, Trinity College Dublin, Ireland Abstract. This paper describes an analysis, and the tools and methods used to produce it, of the practical and logical implications of unifying common linked data vocabularies into a single logical model. In order to support any type of reasoning or even just simple type-checking, the vocabularies that are referenced by linked data statements need to be unified into a complete model wherever they reference or reuse terms that have been defined in other linked data vocabularies. Strong interdependencies between vocabularies are common and a large number of logical and practical problems make this unification inconsistent and messy. However, the situation is far from hopeless. We identify a minimal set of necessary fixes that can be carried out to make a large number of widely-deployed vocabularies mutually compatible, and a set of wider-ranging recommendations for linked data ontology design best practice to help alleviate the problem in future. Finally we make some suggestions for improving OWL’s support for distributed authoring and ontology reuse in the wild. Keywords: Linked Data, Reasoning, Data Quality 1. Introduction One of the central tenets of the Linked Data movement is the reuse of terms from existing well- known vocabularies [Bizer09] when developing new schemata or datasets. The semantic web infrastructure, and the RDF, RDFS and OWL languages, support this with their inherently distributed and modular nature. In practice, through vocabulary reuse, linked data schemata adopt knowledge models that are based on multiple, independently devised ontologies that often exhibit varying definitional semantics [Hogan12].

This paper describes our tools and method for an evaluation of the practical and logical implications of combining common linked data vocabularies into a single local logical model for the purpose of reasoning or performing quality evalua- tions. These vocabularies need to be unified to form a combined model because they reference or reuse terms from other linked data vocabularies and thus the definitions of those terms must be imported. We found that strong interdependencies between vocabularies are common and that a significant number of logical and practical problems make this model unification inconsistent. In addition to identifying problems, this paper suggests a set of recommendations for linked data ontology design best practice.

  • A User-Friendly Interface to Browse and Find DOAP Projects with Doap:Store
    A user-friendly interface to browse and find DOAP projects with doap:store Alexandre Passant Universit´eParis IV Sorbonne, Laboratoire LaLICC, Paris, France [email protected] 1 Motivation The DOAP[2] vocabulary is now widely used by people - and organizations - to describe their projects using Semantic Web standards. Yet, since files are spread around the Web, there is no easy way to find a project regarding its metadata. Recently, Ping The Semantic Web1 (PTSW) and Semantic Radar2 plugin for Firefox introduced a new way to discover Semantic Web documents[1]: by brows- ing the Web, users ping the PTSW service so that it can maintain a contineously updated list of Semantic Web document URIs. Thus, the idea of doap:store - http://doapstore.org is to provide a user- friendly interface, easily accessible for not RDF-aware users, to find and browse DOAP projects, using PTSW as a provider of data sources. This way, users do not have to register to promote a project as in freshmeat3 or related services, but just need to publish some DOAP files on their websites to benefit of this distributed architecture. doap:store is the first implemented service using PTSW data sources to provide such browsing and querying features. 2 Architecture doap:store involves 3 main components: – A crawler: Running hourly, a tiny script parses the list of latest DOAP pings received by PTSW and then put each related RDF files into a triple-store; – A triple-store: The core of the system, storing RDF files retrieved thanks to the crawler, and providing SPARQL capabilities to be used by the user- interface that is plugged on the endpoint; – A user-interface: A simple interface, offering a list of latest retrieved projects, a case-insensitive tagcloud of programming languages, and a search engine to find DOAP projects regarding various criteria in a easy way.

  • Combining RDF Vocabularies for Expert Finding
    Combining RDF Vocabularies for Expert Finding Boanerges Aleman-Meza1, Uldis Boj¯ars2, Harold Boley3, John G. Breslin2, Malgorzata Mochol4, Lyndon JB Nixon4, Axel Polleres2,5, and Anna V. Zhdanova5 1 LSDIS Lab, University of Georgia, USA 2 DERI, National University of Ireland, Galway 3 University of New Brunswick and National Research Council, Canada 4 Free University of Berlin, Germany 5 Universidad Rey Juan Carlos, Madrid, Spain 6 University of Surrey, UK Abstract. This paper presents a framework for the reuse and extension of ex- isting, established vocabularies in the Semantic Web. Driven by the primary ap- plication of expert finding, we will explore the reuse of vocabularies that have attracted a considerable user community already (FOAF, SIOC, etc.) or are de- rived from de facto standards used in tools or industrial practice (such as vCard, iCal and Dublin Core). This focus guarantees direct applicability and low entry barriers, unlike when devising a new ontology from scratch. The Web is already populated with several vocabularies which complement each other (but also have considerable overlap) in that they cover a wide range of necessary features to adequately describe the expert finding domain. Little effort has been made so far to identify and compare existing approaches, and to devise best practices on how to use and extend various vocabularies conjointly. It is the goal of the re- cently started ExpertFinder initiative to fill this gap. In this paper we present the ExpertFinder framework for reuse and extension of existing vocabularies in the Semantic Web. We provide a practical analysis of overlaps and options for com- bined use and extensions of several existing vocabularies, as well as a proposal for applying rules and other enabling technologies to the expert finding task.
