    This paper presents the semantic portal MUSEUMFINLAND for publishing museum collections on the Semantic Web. It is shown how museums with their semantically rich and interrelated collection content can create a large, consolidated semantic collection portal together on the web. By semantic web techniques, it is possible to make collections semantically interoparable and provide the museum visitors with inntelligent content-based search and browsing services to the global collection base.

    Abstract. Ontologies and vocabularies are a key resource for creating interoperable metadata on the Semantic Web. To make finding and using ontologies easier, the idea of Ontology Repositories has been introduced with current implementations including eg the NCBO Bioportal, ONKI and Cupboard. There is a genuine need for different kinds of Ontology Repositories, each focusing on different kinds specific user-needs, different ontologies and different organizational requirements which cannot be addressed by a ...

    Abstract. This paper presents a deployed semantic web application in the cultural domain: the semantic portal MuseumFinland. It is a demonstration of a community portal and a publication channel by which heterogeneous collection database contents of different museums can be published on the Semantic Web. By semantic web techniques, it is possible to make collections semantically interoperable and provide the museum visitors with intelligent content-based search and browsing services to the global collection base.

    More and more museum collections are published on the Web. A problem in this work is the heterogeneous nature of the (meta) data catalogued in the databases. From the data perspective, heterogeneity is due to the different nonstandard cataloguing formats and practices used, the incomplete or partly erroneus data entered, the different and ad hoc semantic taxonomies in use, and different (natural) languages employed in descriptions. From the system perspective, the collections are incompatible: the databases have ...

    Abstract. HEALTHFINLAND is a national semantic publishing system for providing Finnish citizens with reliable, up-to-date information about health. The system consists of three parts: 1) a centralized service of health ontologies with tools, 2) a semantic content creation channel based on several distributed health organizations, and 3) an intelligent semantic portal aggegating and presenting the contents from intuitive and health promoting end-user perspectives. The system demontrates how semantic web techniques can be applied to ...

    Digital libraries and memory organizations such as museums, libraries and archieves, are heading major challenges in the digital age. We are moving fast from preserving and cataloguing physical objects such as books or artifacts to archival of digital artifacts such as electronic copies of texts or images of the physical artifacts. While the digitalized collections are available in growing numbers, accessing, indexing and searching these collections is far from trivial. A widely shared goal of cultural institutions and libraries is to provide the ...

    TerveSuomi.fi is a national health portal under construction that provides citizens with reliable and up-to-date health information created by the National Public Health Institute1 and affiliated health organizations in Finland. The content includes metadata of thousands of web documents such as web pages, articles (eg, “Dangers of smoking”), reports, campaign information (eg, “National non-smoking week”), news, services, and other information related to health. Our technical challenge is to develop methods and tools 1) for creating and annotating the content by distributed ...

    We present ONKI ontology server, a” mash-up” approach for integrating ontology library services with semantic web applications. The idea of ONKI is to provide applications with ready-to-use ontology service functionalities, such as semantic autocompletion, browsing, and annotation support, at the user interface level using AJAX mash-up technologies. The system is being integrated with various semantic web applications.

    Content in semantic Web portals is often projected along application specific navigational taxonomies and linked semantically. This paper presents a logic-based method and a server Ontodella for these tasks. We argue that logic rules between the content layer and the application layer add flexibility and better architectural separation of content and functionality. The system has been implemented and applied succesfully in several semantic portals

    Many semantic portals use faceted browsing, where the facets are based on the underlying indexing ontologies of the content. However, in many cases, like in medical applications, the ontologies may be very large and complex, and do not provide the end-user with intuitive facet hierarchies for conceptualizing the content, for formulating queries, and for classifying the search results. We argue that in such cases end-user facets should be separated from the annotation ontologies, and show how to generalize the semantic view-based search ...

    This deliverable defines the functional and non-functional requirements of the MeMAD prototype system, based on input concerning the tools developed in WP2, WP3, WP4 and WP5 and based on the project's overall use cases from which many requirements will be dictated. This initial version introduces the methodology that will be followed to construct the project's prototype requirements and exchange format specifications. We then identify relevant stakeholders and processes for the project's prototypes from the media production and consumption chain. We define an initial set of user stories for the prototype system, from which the functional, non-functional and data interchange format requirements for the first version of the MeMAD prototype are then derived.

    This deliverable primarily describes the MeMAD ontology which builds on top of the EBU Core data model. A number of additional classes and properties are defined in order to cope with the original set of metadata delivered by the MeMAD data providers (INA and Yle). Furthermore, this deliverable describes two tools that enable to convert the legacy metadata coming from both INA and Yle into RDF, the W3C standard for representing knowledge graph on the web, following the MeMAD ontology. During this process, metadata is harmonized and enriched semantically enabling to perform queries across sources. This deliverable describes also a number of tools that perform named entity recognition and disambiguation on both automatic transcription and true subtitles of TV programs. These tools existed prior to the beginning of MeMAD but they have been further improved and developed during the first year of the project (e.g. development of API, specific training to MeMAD audiovisual material). The ...

    This deliverable describes a joint collection of libraries and tools for multimodal content analysis created by the MeMAD project partners. These tools have been further improved and developed during the first year of the project. The description of the components is divided into the visual and auditory domain, and these are further subdivided into differ- ent themes. As part of this deliverable, the open source components have been gathered into a joint software collection of tools and libraries publicly available on GitHub. Finally, five scientific publications are appended to the report, which describe the technological advances related to these components that has been made so far in the project.

    The Semantic Web is based on using shared ontologies for enabling semantically disambiguated data exchange between distributed systems on the web. This requires, from the ontology publisher’s viewpoint, efficient means for publishing ontologies on the web to ensure the availability and acceptance of the ontologies. From the ontology user’s viewpoint, support services are needed for utilizing ontologies easily and cost-effectively in the users ’ own systems that are typically legacy systems without ontology support. This paper presents the ONKI ontology server for addressing these vital needs. For the publisher, ONKI provides a server and a Simple Knowledge Organization (SKOS) compatible lightweight ontology browser with ready-made web interfaces for making ontologies available both for human and machine users. For external legacy and other applications, ONKI provides centralized ontology services for semantic disambiguation, concept finding, and concept fetching. A major contributio...

    Abstract. Ontology repository systems are used for publishing and sharing ontologies. However, currently the repositories form separate islands of ontologies, which hinders the user from finding and utilizing the most suitable ontological concepts and ontologies on a global level. In contrast, this paper presents the idea of creating a network of Linked Open Ontology Services (LOOS) based on a set of ontology services that publish their content via a shared API. This facilitates global search and browsing over all ontologies in the network. LOOS has been implemented in the National Finnish Ontology Service ONKI serving currently 79 ontologies.

    Abstract. Ontologies evolve over time, when they are altered to correct errors, to accommodate new information or to adjust the representation of the domain. Hence there is a need for methods and means to manage the ontology evolution in order to ensure that applications using different versions of an ontology remain compatible with respect each other and metadata annotated. In this paper an ontology versioning framework is presented to enable ontology versioning. The presented approach aims to provide means for ...

    Abstract. The Resource Description Framework RDF is used to describe content, such as HTML pages and other documents, for the machines to interpret on the Semantic Web. In contrast, we consider the problem of rendering RDF content for the human user by transforming RDF descriptions into a repository of semantically indexed and linked HTML pages. This paper presents a two level method for such a transformation: On the HTML level, the layout of the pages can be described by an HTML designer by using templates and ...

    Abstract. Finding ontologies and concepts from a collection of ontologies is a recurring task in many use cases, such as content indexing, searching, and ontology developing. To facilitate this, efficient search and browsing methods are needed. This paper introduces ONKI2, an ontology browser providing a user interface for a repository of ontologies. The system provides a multi-facet search facility for finding an ontology. Finding concepts is supported by autocompletion-based text search that can be refined with additional ...

    Abstract. We introduce the idea of utilizing ontologies as a service for query expansion, based on an AJAX widget. This ONKI Query Expansion Widget can be integrated into the search input field of a traditional keyword-based legacy system by one line of JavaScript code, making the search system semantic. For example, when searching for “tools”, also “hammers”,“axes” etc. can be found based on the underlying hyponymy. In the same vein, the spatial relations of a geo-ontology or temporal relations can be utilized. Application of ...
