    Abstract
    This volume contains the lecture notes of the 13th Reasoning Web Summer School, RW 2017, held in London, UK, in July 2017. In 2017, the theme of the school was "Semantic Interoperability on the Web", which encompasses subjects such as data integration, open data management, reasoning over linked data, database to ontology mapping, query answering over ontologies, hybrid reasoning with rules and ontologies, and ontology-based dynamic systems. The papers of this volume focus on these topics and also address foundational reasoning techniques used in answer set programming and ontologies.

    Abstract
    iQvoc is a new open source SKOS-XL vocabulary management tool developed by the Federal Environment Agency, Germany, and innoQ Deutschland GmbH. Its immediate purpose is maintaining and publishing reference vocabularies in the upcoming Linked Data cloud of environmental information, but it may be easily adapted to host any SKOS- XL compliant vocabulary. iQvoc is implemented as a Ruby on Rails application running on top of JRuby - the Java implementation of the Ruby Programming Language. To increase the user experience when editing content, iQvoc uses heavily the JavaScript library jQuery.

    Abstract
    The PeriodO period gazetteer documents definitions of historical period names. Each entry of the gazetteer identifies the definition of a single period. To be included in the gazetteer, a definition must a) give the period a name, b) impose some temporal bounds on the period, c) have some implicit or explicit association with a geographical region, and d) have been formally or informally published in some citable source. Much care has been put into giving period definitions stable identifiers that can be resolved to RDF representations of period definitions. Anyone can propose additions of new definitions to PeriodO, and we have implemented an open source web service and browser-based client for distributed versioning and collaborative maintenance of the gazetteer.

    Abstract
    Semantic Enrichment Enabling Sustainability of Archaeological Links (SENESCHAL) was a project coordinated by the Hypermedia Research Unit at the University of South Wales. The project aims included widening access to key vocabulary resources. National cultural heritage thesauri and vocabularies are used by both national organizations and local authority Historic Environment Records and could potentially act as vocabulary hubs for the Web of Data. Following completion, a set of prominent UK archaeological thesauri and vocabularies is now freely available as Linked Open Data (LOD) via http://www.heritagedata.org - together with open source web services and user interface controls. This presentation will reflect on work done to date for the ARIADNE FP7 infrastructure project (http://www.ariadne-infrastructure.eu) mapping between archaeological vocabularies in different languages and the utility of a hub architecture. The poly-hierarchical structure of the Getty Art & Architecture Thesaurus (AAT) was extracted for use as an example mediating structure to interconnect various multilingual vocabularies originating from ARIADNE data providers. Vocabulary resources were first converted to a common concept-based format (SKOS) and the concepts were then manually mapped to nodes of the extracted AAT structure using some judgement on the meaning of terms and scope notes. Results are presented along with reflections on the wider application to existing European archaeological vocabularies and associated online datasets.

    Abstract
    The BAsel Register of Thesauri, Ontologies & Classifications (BARTOC, http://bartoc.org) is a bibliographic database aiming to record metadata of as many Knowledge Organization Systems as possible. It has a facetted, responsive web design search interface in 20 EU languages. With more than 1'300 interdisciplinary items in 77 languages, BARTOC is the largest database of its kind, multilingual both by content and features, and it is still growing. This being said, the demonstration of BARTOC would be suitable for topic nr. 10 [Multilingual and Interdisciplinary KOS applications and tools]. BARTOC has been developed by the University Library of Basel, Switzerland. It is rooted in the tradition of library and information science of collecting bibliographic records of controlled and structured vocabularies, yet in a more contemporary manner. BARTOC is based on the open source content management system Drupal 7.

    Abstract
    In this lecture we will discuss and introduce challenges of integrating openly available Web data and how to solve them. Firstly, while we will address this topic from the viewpoint of Semantic Web research, not all data is readily available as RDF or Linked Data, so we will give an introduction to different data formats prevalent on the Web, namely, standard formats for publishing and exchanging tabular, tree-shaped, and graph data. Secondly, not all Open Data is really completely open, so we will discuss and address issues around licences, terms of usage associated with Open Data, as well as documentation of data provenance. Thirdly, we will discuss issues connected with (meta-)data quality issues associated with Open Data on the Web and how Semantic Web techniques and vocabularies can be used to describe and remedy them. Fourth, we will address issues about searchability and integration of Open Data and discuss in how far semantic search can help to overcome these. We close with briefly summarizing further issues not covered explicitly herein, such as multi-linguality, temporal aspects (archiving, evolution, temporal querying), as well as how/whether OWL and RDFS reasoning on top of integrated open data could be help.

    Abstract
    The research study as reported here is an attempt to explore the possibilities of an AI/ML-based semi-automated indexing system in a library setup to handle large volumes of documents. It uses the Python virtual environment to install and configure an open source AI environment (named Annif) to feed the LOD (Linked Open Data) dataset of Library of Congress Subject Headings (LCSH) as a standard KOS (Knowledge Organisation System). The framework deployed the Turtle format of LCSH after cleaning the file with Skosify, applied an array of backend algorithms (namely TF-IDF, Omikuji, and NN-Ensemble) to measure relative performance, and selected Snowball as an analyser. The training of Annif was conducted with a large set of bibliographic records populated with subject descriptors (MARC tag 650$a) and indexed by trained LIS professionals. The training dataset is first treated with MarcEdit to export it in a format suitable for OpenRefine, and then in OpenRefine it undergoes many steps to produce a bibliographic record set suitable to train Annif. The framework, after training, has been tested with a bibliographic dataset to measure indexing efficiencies, and finally, the automated indexing framework is integrated with data wrangling software (OpenRefine) to produce suggested headings on a mass scale. The entire framework is based on open-source software, open datasets, and open standards.

    Abstract
    Der Begriff Ontologie stammt ursprünglich aus der Metaphysik, einem Teilbereich der Philosophie, welcher sich um die Erkenntnis der Grundstruktur und Prinzipien der Wirklichkeit bemüht. Ontologien befassen sich dabei mit der Frage, welche Dinge auf der fundamentalsten Ebene existieren, wie sich diese strukturieren lassen und in welchen Beziehungen diese zueinanderstehen. In der Informationswissenschaft hingegen werden Ontologien verwendet, um das Vokabular für die Beschreibung von Wissensbereichen zu formalisieren. Ziel ist es, dass alle Akteure, die in diesen Bereichen tätig sind, die gleichen Konzepte und Begrifflichkeiten verwenden, um eine reibungslose Zusammenarbeit ohne Missverständnisse zu ermöglichen. So definierte zum Beispiel die Dublin Core Metadaten Initiative 15 Kernelemente, die zur Beschreibung von elektronischen Ressourcen und Medien verwendet werden können. Jedes Element wird durch eine eindeutige Bezeichnung (zum Beispiel identifier) und eine zugehörige Konzeption, welche die Bedeutung dieser Bezeichnung möglichst exakt festlegt, beschrieben. Ein Identifier muss zum Beispiel laut der Dublin Core Ontologie ein Dokument basierend auf einem zugehörigen Katalog eindeutig identifizieren. Je nach Katalog kämen daher zum Beispiel eine ISBN (Katalog von Büchern), ISSN (Katalog von Zeitschriften), URL (Web), DOI (Publikationsdatenbank) etc. als Identifier in Frage.

    Abstract
    Linked Open Data initiative has played a vital role in the realization of the Semantic Web at a global scale by publishing and interlinking diverse data sources on the Web. Access to this huge amount of Linked Data presents exciting benefits and opportunities. However, the inherent complexity attached to Linked Data understanding, lack of potential use cases and applications which can consume Linked Data hinders its full exploitation by naïve web users and developers. This book aims to address these core limitations of Linked Open Data and contributes by presenting: (i) Conceptual model for fundamental understanding of Linked Open Data sphere, (ii) Linked Data application to search, consume and aggregate various Linked Data resources, (iii) Semantification and interlinking technique for conversion of legacy data, and (iv) Potential application areas of Linked Open Data.

    Abstract
    Ontologies are viewed as the silver bullet for many applications, but in open or evolving systems, different parties can adopt different ontologies. This increases heterogeneity problems rather than reducing heterogeneity. This book proposes ontology matching as a solution to the problem of semantic heterogeneity, offering researchers and practitioners a uniform framework of reference to currently available work. The techniques presented apply to database schema matching, catalog integration, XML schema matching and more. Ontologies tend to be found everywhere. They are viewed as the silver bullet for many applications, such as database integration, peer-to-peer systems, e-commerce, semantic web services, or social networks. However, in open or evolving systems, such as the semantic web, different parties would, in general, adopt different ontologies. Thus, merely using ontologies, like using XML, does not reduce heterogeneity: it just raises heterogeneity problems to a higher level. Euzenat and Shvaiko's book is devoted to ontology matching as a solution to the semantic heterogeneity problem faced by computer systems. Ontology matching aims at finding correspondences between semantically related entities of different ontologies. These correspondences may stand for equivalence as well as other relations, such as consequence, subsumption, or disjointness, between ontology entities. Many different matching solutions have been proposed so far from various viewpoints, e.g., databases, information systems, artificial intelligence. With Ontology Matching, researchers and practitioners will find a reference book which presents currently available work in a uniform framework. In particular, the work and the techniques presented in this book can equally be applied to database schema matching, catalog integration, XML schema matching and other related problems. The objectives of the book include presenting (i) the state of the art and (ii) the latest research results in ontology matching by providing a detailed account of matching techniques and matching systems in a systematic way from theoretical, practical and application perspectives.

    Abstract
    Eine einheitliche Sacherschließung in Deutschland wird durch die Vielzahl an vorhandenen und verwendeten Erschließungssystemen, Universal-, Fachklassifikationen und Fachthesauri erschwert. Den Benutzern von Bibliothekskatalogen oder Datenbanken fällt es daher schwer, themenspezifische Recherchen in heterogen erschlossenen Datenbeständen durchzuführen. In diesem Fall müssen die Nutzer derzeit nämlich den Umgang mit mehreren Erschließungsinstrumenten erlernen und verschiedene Suchanfragen anwenden, um das gewünschte Rechercheergebnis datenbankübergreifend zu erreichen. Um dem Benutzer einen einheitlichen Zugang zu heterogen erschlossenen Datenbeständen zu gewährleisten und gleichzeitig auch den Arbeitsaufwand für die Bibliothekare zu reduzieren, ist die Erstellung eines so genannten "Integrierten Retrievals" sinnvoll. Durch die Verknüpfung der unterschiedlichen Sacherschließungssysteme mit Hilfe von Konkordanzen wird es dem Nutzer ermöglicht, mit einem ihm vertrauten Vokabular eine sachliche Recherche in unterschiedlich erschlossenen Datenbeständen durchzuführen, ohne die spezifischen Besonderheiten der verschiedenen Erschließungsinstrumente kennen zu müssen. In dieser Arbeit sind exemplarisch drei Abbildungen für den Fachbereich der Bibliotheks- und Informationswissenschaften zwischen den für Deutschland wichtigsten Sacherschließungssystemen Dewey-Dezimalklassifikation (DDC), Regensburger Verbundklassifikation (RVK) und Schlagwortnormdatei (SWD) erstellt worden. Die Ergebnisse dieser Arbeit sollen einen ersten Überblick über spezifische Problemfelder und Möglichkeiten der hier erstellten Konkordanzen DDC - RVK, SWD - DDC und SWD - RVK liefern, um damit die Erstellung eines zukünftigen Recherchetools (und gegebenenfalls einer Klassifizierungshilfe) voranzutreiben. Die erstellten Konkordanzen liegen der Arbeit als Anhang bei.

    Abstract
    The Brazilian Government has made a massive volume of structured, semi-structured and non-structured public data available on the web to ensure that the administration is as transparent as possible. Subsequently, providing applications with enough capability to handle this "big data environment" so that vital and decisive information is readily accessible, has become a tremendous challenge. In this environment, data processing is done via new approaches in the area of information and computer science, involving technologies and processes for collecting, representing, storing and disseminating information. Along these lines, this paper presents a conceptual model, the technical architecture and the prototype implementation of a tool, denominated DBgoldbr, designed to classify government public information with the help of ontologies, by transforming open data into open linked data. To achieve this objective, we used "soft system methodology" to identify problems, to collect users needs and to design solutions according to the objectives of specific groups. The DBgoldbr tool was designed to facilitate the search for open data made available by many Brazilian government institutions, so that this data can be reused to support the evaluation and monitoring of social programs, in order to support the design and management of public policies.

    Abstract
    Currently, several datasets released in a Linked Open Data format are available at a national and international level, but the lack of shared strategies concerning the definition of concepts related to the statistical publishing community makes difficult a comparison among given facts starting from different data sources. In order to guarantee a shared representation framework for what concerns the dissemination of statistical concepts about graduates, we developed SW4AL, an ontology-based system for graduate's surveys domain. The developed system transforms low-level data into an enriched information model and is based on the AlmaLaurea surveys covering more than 90% of Italian graduates. SW4AL: i) semantically describes the different peculiarities of the graduates; ii) promotes the structured definition of the AlmaLaurea data and the following publication in the Linked Open Data context; iii) provides their reuse in the open data scope; iv) enables logical reasoning about knowledge representation. SW4AL establishes a common semantic for addressing the concept of graduate's surveys domain by proposing the creation of a SPARQL endpoint and a Web based interface for the query and the visualization of the structured data.

    Abstract
    In recent years, cultural heritage institutions have been exploring the benefits of applying Linked Open Data to their catalogs and digital materials. Innovative and creative methods have emerged to publish and reuse digital contents to promote computational access, such as the concepts of Labs and Collections as Data. Data quality has become a requirement for researchers and training methods based on artificial intelligence and machine learning. This article explores how the quality of Linked Open Data made available by cultural heritage institutions can be automatically assessed. The results obtained can be useful for other institutions who wish to publish and assess their collections.

    Abstract
    Das Medium Internet ist im Wandel, und mit ihm ändern sich seine Publikations- und Rezeptionsbedingungen. Welche Chancen bieten die momentan parallel diskutierten Zukunftsentwürfe von Social Web und Semantic Web? Zur Beantwortung dieser Frage beschäftigt sich der Beitrag mit den Grundlagen beider Modelle unter den Aspekten Anwendungsbezug und Technologie, beleuchtet darüber hinaus jedoch auch deren Unzulänglichkeiten sowie den Mehrwert einer mediengerechten Kombination. Am Beispiel des grammatischen Online-Informationssystems grammis wird eine Strategie zur integrativen Nutzung der jeweiligen Stärken skizziert.

    Abstract
    Topic Maps are a standardized modelling approach for the semantic annotation and description of WWW resources. They enable an improved search and navigational access on information objects stored in semi-structured information spaces like the WWW. However, the according standards ISO 13250 and XTM (XML Topic Maps) lack formal semantics, several questions concerning e.g. subclassing, inheritance or merging of topics are left open. The proposed TMUML meta model, directly derived from the well known UML meta model, is a meta model for Topic Maps which enables semantic constraints to be formulated in OCL (object constraint language) in order to answer such open questions and overcome possible inconsistencies in Topic Map repositories. We will examine the XTM merging conditions and show, in several examples, how the TMUML meta model enables semantic constraints for Topic Map merging to be formulated in OCL. Finally, we will show how the TM validation process, i.e., checking if a Topic Map is well formed, includes our merging conditions.
