    Abstract
    This article presents an Italian experience of developing streamlined semantic interoperability between the Italian Thesaurus of Nuovo soggettario and the Library of Congress Subject Headings (LCSH). This ongoing project must take into consideration the differences between the two indexing tools, while the criteria on which the resulting actions are based are being clarified continually. Reciprocal interoperability, thanks to the Simple Knowledge Organization System format, enables us to create links with English language subject headings. The National Central Library of Florence is studying methods of automatically catching LCSH equivalents and the question of how to take advantage of both Semantic Web outputs and the multilingual dataset of Wikidata.

    Abstract
    Since the 90s, we have seen an explosion of information and with it there is an increase in the need for data and information aggregation systems that store and manage information. However, most of the information sources apply different Knowledge Organizations Systems (KOS) to describe the content of stored data. This heterogeneous mix of KOS in different systems complicate access and seamless sharing of information and knowledge. Concordances also known as cross-concordances or terminology mappings map different (KOS) to each other for improvement of information retrieval in such heterogeneous mix of systems. (Mayr 2010, Keil 2012). Also for coherent indexing with different terminologies, mappings are considered to be a valuable and essential working tool. However, despite efforts at standardization (e.g. SKOS, ISO 25964-2, Keil 2012, Soergel 2011); there is a significant scarcity of concordances that has led an inability to establish uniform exchange formats as well as methods and tools for maintaining mappings and making them easily accessible. This is particularly true in the field of library classification schemes. In essence, there is a lack of infrastructure for provision/exchange of concordances, their management and quality assessment as well as tools that would enable semi-automatic generation of mappings. The project "coli-conc" therefore aims to address this gap by creating the necessary infrastructure. This includes the specification of a data format for exchange of concordances (JSKOS), specification and implementation of web APIs to query concordance databases (JSKOS-API), and a modular web application to enable uniform access to knowledge organization systems, concordances and concordance assessments (Cocoda).
    The focus of the project "coli-conc" lies in semi-automatic creation of mappings between different KOS in general and the two important library classification schemes in particular - Dewey classification system (DDC) and Regensburg classification system (RVK). In the year 2000, the national libraries of Germany, Austria and Switzerland adopted DDC in an endeavor to develop a nation-wide classification scheme. But historically, in the German speaking regions, the academic libraries have been using their own home-grown systems, the most prominent and popular being the RVK. However, with the launch of DDC, building concordances between DDC and RVK has become an imperative, although it is still rare. The delay in building comprehensive concordances between these two systems has been because of major challenges posed by the sheer largeness of these two systems (38.000 classes in DDC and ca. 860.000 classes in RVK), the strong disparity in their respective structure, the variation in the perception and representation of the concepts. The challenge is compounded geometrically for any manual attempt in this direction. Although there have been efforts on automatic mappings (OAEI Library Track 2012 -- 2014 and e.g. Pfeffer 2013) in the recent years; such concordances carry the risks of inaccurate mappings, and the approaches are rather more suitable for mapping suggestions than for automatic generation of concordances (Lauser 2008; Reiner 2010). The project "coli-conc" will facilitate the creation, evaluation, and reuse of mappings with a public collection of concordances and a web application of mapping management. The proposed presentation will give an introduction to the tools and standards created and planned in the project "coli-conc". This includes preliminary work on DDC concordances (Balakrishnan 2013), an overview of the software concept, technical architecture (Voß 2015) and a demonstration of the Cocoda web application.

    Abstract
    Research information can be useful to science stake-holders for discovering, evaluating and planning research activities. In the Netherlands, the institute tasked with the stewardship of national research information is DANS (Data Archiving and Networked Services). DANS is the home of NARCIS, the national portal for research information, which uses a similarly named national research classification. The NARCIS Classification assigns symbols to represent the knowledge bases of contributing scholars. A recent research stream in knowledge organization known as comparative classification uses two or more classifications experimentally to generate empirical evidence about coverage of conceptual content, population of the classes, and economy of classification. This paper builds on that research in order to further understand the comparative impact of the NARCIS Classification alongside a classification designed specifically for information resources. Our six cases come from the DANS project Knowledge Organization System Observatory (KOSo), which itself is classified using the Information Coding Classification (ICC) created in 1982 by Ingetraut Dahlberg. ICC is considered to have the merits of universality, faceting, and a top-down approach. Results are exploratory, indicating that both classifications provide fairly precise coverage. The inflexibility of the NARCIS Classification makes it difficult to express complex concepts. The meta-ontological, epistemic stance of the ICC is apparent in all aspects of this study. Using the two together in the DANS KOS Observatory will provide users with both clarity of scientific positioning and ontological relativity.

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    Ontologies are increasingly seen as a new type of knowledge organization system (KOS) besides traditional ones such as classification schemes or thesauri. Consequently, there are efforts to compare them with and map them to other KOS. This paper argues that only ontologies for reality representation are useful subjects of such comparisons and mappings. These ontologies are difficult to distinguish from other "data modelling" - types of ontology, since both can be represented through the popular Web Ontology Language (OWL). Data modelling ontologies such as Simple Knowledge Organization Systems (SKOS) are useful instruments for establishing interoperability between KOS in the sense of publishing and accessing data and data models in a uniform way as well as for relating them to each other. Discriminating these two understandings of ontologies particularly supports comparisons and mappings between traditional KOS and ontologies. In practice, such efforts are still impeded by the absence of standards or guidelines for vocabulary control in ontologies. Moreover, this paper emphasizes that methods for constructing and evaluating reality representation ontologies can be useful to re-engineer traditional KOS. This makes them become more interoperable in the sense of combinable, but also more useful in the sense of improving search expansion results and reusable for different purposes.

    Abstract
    This paper presents a system which creates and visualizes probabilistic semantic links between concepts in a thesaurus and classes in a classification system. For creating the links, we build on the Polylingual Labeled Topic Model (PLL-TM) (Posch et al., in KI 2015: advances in artificial intelligence, 2015). PLL-TM identifies probable thesaurus descriptors for each class in the classification system by using information from the natural language text of documents, their assigned thesaurus descriptors and their designated classes. The links are then presented to users of the system in an interactive visualization, providing them with an automatically generated overview of the relations between the thesaurus and the classification system.

    Abstract
    Since its launch in 1998, the initiative introducing the Functional Requirements of Bibliographic Records (FRBR) has provided and established a new standar for the representation of bibliographic data. Following the success of the Functional Requirements for Bibliographic Records, a number of related modules have been developed, complementing the initial standard. One of the most recent and promising efforts in this field is the initiative surrounding the development and approval of the Functional Requirements for Subject Authority Data (FRSAD). FRSAD is a specification of the requirements for modelling subject authority data, based on a conceptual model, which combines various theoretical aspects and technical modelling strategies. This article analyses the model's adaptability and appropriateness in an environment of heterogeneous and distributed systems and makes some suggestions for further improvements.

    Abstract
    This exploratory study examined Linked Data (LD) schemas/ontologies and data models proposed or in use by libraries around the world using MAchine Readable Cataloging (MARC) as a basis for comparison of the scope and extensibility of these potential new standards. The researchers selected 14 libraries from national libraries, academic libraries, government libraries, public libraries, multi-national libraries, and cultural heritage centers currently developing Library Linked Data (LLD) schemas. The choices of models, schemas, and elements used in each library's LD can create interoperability issues for LD services because of substantial differences between schemas and data models evolving via local decisions. The researchers observed that a wide variety of vocabularies and ontologies were used for LLD including common web schemas such as Dublin Core (DC)/DCTerms, Schema.org and Resource Description Framework (RDF), as well as deprecated schemas such as MarcOnt and rdagroup1elements. A sharp divide existed as well between LLD schemas using variations of the Functional Requirements for Bibliographic Records (FRBR) data model and those with different data models or even with no listed data model. Libraries worldwide are not using the same elements or even the same ontologies, schemas and data models to describe the same materials using the same general concepts.

    Abstract
    The compilation of terminological vocabularies plays a central role in the organization and retrieval of scientific texts. Both simple keyword lists as well as sophisticated modellings of relationships between terminological concepts can make a most valuable contribution to the analysis, classification, and finding of appropriate digital documents, either on the Web or within local repositories. This seems especially true for long-established scientific fields with various theoretical and historical branches, such as linguistics, where the use of terminology within documents from different origins is sometimes far from being consistent. In this short paper, we report on the early stages of a project that aims at the re-design of an existing domain-specific KOS for grammatical content grammis. In particular, we deal with the terminological part of grammis and present the state-of-the-art of this online resource as well as the key re-design principles. Further, we propose questions regarding ramifications of the Linked Open Data and Semantic Web approaches for our re-design decisions.

    Abstract
    This proposal presents the methodology of indexing with images suggested by De Brito and Caribé (2015). The imagetic model is used as a compatible mechanism with FRSAD for a global information share and use of subject data, both within the library sector and beyond. The conceptual model of imagetic indexing shows how images are related to topics and 'key-images' are interpreted as nomens to implement the FRSAD model. Indexing with images consists of using images instead of key-words or descriptors, to represent and organize information. Implementing the imaged navigation in OPACs denotes multiple advantages derived from this rethinking the OPAC anew, since we are looking forward to sharing concepts within the subject authority data. Images, carrying linguistic objects, permeate inter-social and cultural concepts. In practice it includes translated metadata, symmetrical multilingual thesaurus, or any traditional indexing tools. iOPAC embodies efforts focused on conceptual levels as expected from librarians. Imaged interfaces are more intuitive since users do not need specific training for information retrieval, offering easier comprehension of indexing codes, larger conceptual portability of descriptors (as images), and a better interoperability between discourse codes and indexing competences affecting positively social and cultural interoperability. The imagetic methodology deploys R&D fields for more suitable interfaces taking into consideration users with specific needs such as deafness and illiteracy. This methodology arouse questions about the paradigms of the primacy of orality in information systems and pave the way to a legitimacy of multiple perspectives in document indexing by suggesting a more universal communication system based on images. Interdisciplinarity in neurosciences, linguistics and information sciences would be desirable competencies for further investigations about he nature of cognitive processes in information organization and classification while developing assistive KOS for individuals with communication problems, such autism and deafness.

    Abstract
    The purpose of this paper is to examine how complexities of pre-coordinated classes can influence mapping quality. Though various kinds of mappings among vocabularies have been achieved and applied, there is little research directly pointing out the problems that hinder the mapping quality. This paper focuses on the relationship between the grammatical forms of pre-coordinated classes and semantic mapping quality, in order to provide useful assistance to the setting and mapping of complex concepts in knowledge organization systems. A review of the literature on vocabulary interoperability and an empirical study of pre-coordinated classes in Dewey Decimal Classification (DDC) and Chinese Library Classification (CLC) are presented. As research objects, the authors have selected two main classes, mathematics and astronomy, in both DDC and CLC. Distributions in the selected classes are described based on the definition and division of pre-coordinated classes. We conclude that the high proportion of pre-coordinated classes in both DDC and CLC greatly increase the difficulty of achieving mapping quality.

    Abstract
    This paper describes recent work on registering Resource Description Framework (RDF) versions of the entities and relationships from the Functional Requirements for Bibliographic Records (FRBR) and Functional Requirements for Authority Data (FRAD) models developed by the International Federation of Library Associations and Institutions (IFLA). FRBR was developed several years before FRAD, and is under-developed in areas which FRAD was expected to cover; FRAD therefore makes significance reference to FRBR. Similarly, FRAD leaves a full treatment of subject authority data to the ongoing development of Functional Requirements for Subject Authority Data (FRSAD) which was finalised during 2010. Although the FRBR Review Group is charged with consolidating all three models in due course, the RDF versions of FRBR, FRAD, and FRSAD are being created in separate namespaces, with a separate Web Ontology Language (OWL) ontology to connect the three models. The paper discusses interoperability issues arising from this work. Such issues include class definitions and sub-classes, reciprocal properties, and disjoint classes and properties. The paper discusses similar work on the International Standard Bibliographic Description (ISBD), also maintained by IFLA, and related issues arising from the RDF representation of the metadata element set of RDA: resource description and access, which is based on the FRBR and FRAD models. The work is ongoing, and the paper updates the original conference presentation to the end of October 2010.

    Abstract
    The Semantic Web consists of data structured for use by computer programs, such as data sets made available under the Linked Open Data initiative. Much of this data is structured following the entity-relationship model encoded in RDF for syntactic interoperability. For semantic interoperability, the semantics of the relationships used in any given dataset needs to be made explicit. Ultimately this requires an inventory of these relationships structured around a relation ontology. This talk will outline a blueprint for such an inventory, including a format for the description/definition of binary and n-ary relations, drawing on ideas put forth in the classification and thesaurus community over the last 60 years, upper level ontologies, systems like FrameNet, the Buffalo Relation Ontology, and an analysis of linked data sets.

    Abstract
    This article proposes an approach to mapping between Knowledge Organization Systems (KOS), including ontologies, classifications, taxonomies, and thesauri and even natural languages, that is based on deep semantics. In this approach, concepts in each KOS are expressed through canonical expressions, such as description logic formulas, that combine atomic (or elemental) concepts drawn from a core classification. Relationships between concepts within or across KOS can then be derived by reasoning over the canonical expressions. The canonical expressions can also be used to provide a facet-based query formulation front-end for free-text search. The article illustrates this approach through many examples. It presents methods for the efficient construction of canonical expressions (linguistic analysis, exploiting information in the KOS and their hierarchies, and crowdsourcing) that make this approach feasible.
