“…An interesting approach to identify similarity is to map relationships between concepts in the user profile by using ontologies. Fernández et al [12] argue that ontologies can be exploited to structure news items and to annotate them with additional information. Dudev et al [10] propose the creation of user profiles by creating knowledge graphs that model the relationship between different concepts in the Linked Open Data Cloud.…”

In recent years, a number of research works have been carried out to improve the information retrieval process by exploiting external knowledge, e.g., by employing ontologies. Even though ontologies seem to be a promising technique to improve the retrieval process, hardly any study has been performed to evaluate the use of ontologies over a longer time period to model user interests. In this work we introduce an ontology based video recommender system that exploits implicit relevance feedback to capture users' evolving information needs. The system exploits a generic ontology to organise users' interests. We evaluate the recommendations by performing a user-centred multiple time-series study where participants were asked to include the system into their daily news gathering routine. The results of this study suggest that the system can be successfully employed to improve personal information seeking tasks in news domain.

“…It defines, within an XML Schema, metadata related to image parameters, creation information, content description (who, what, when and where), history and intellectual property rights. In collaboration with Ghent University, we have recently modeled these metadata blocks into a DIG35 ontology 7 , following the same guidelines detailed in Section 4. XMP 8 provides a native RDF data model and predefined sets of metadata property definitions such as Dublin Core, basic rights and media management schemas for describing still images.…”

“…NEWS 13 is a completed EU project that aims to combine Semantic Web technologies and web services for improving the news agencies workflow. The project has developed a lightweight RDFS news ontology (in English, Spanish and Italian) based on the IPTC Subject Codes for categorizing the news items and on NITF and NewsML for the metadata management [7,9]. The Neptuno 14 research project has also modeled a lightweight RDFS news ontology representing a newspaper archive.…”

Abstract. For easing the exchange of news, the International Press Telecommunication Council (IPTC) has developed the NewsML Architecture (NAR), an XML-based model that is specialized into a number of languages such as NewsML G2 and EventsML G2. As part of this architecture, specific controlled vocabularies, such as the IPTC News Codes, are used to categorize news items together with other industry-standard thesauri. While news is still mainly in the form of text-based stories, these are often illustrated with graphics, images and videos. Media-specific metadata formats, such as EXIF, DIG35 and XMP, are used to describe the media. The use of different metadata formats in a single production process leads to interoperability problems within the news production chain itself. It also excludes linking to existing web knowledge resources and impedes the construction of uniform end-user interfaces for searching and browsing news content.In order to allow these different metadata standards to interoperate within a single information environment, we design an OWL ontology for the IPTC News Architecture, linked with other multimedia metadata standards. We convert the IPTC NewsCodes into a SKOS thesaurus and we demonstrate how the news metadata can then be enriched using natural language processing and multimedia analysis and integrated with existing knowledge already formalized on the Semantic Web. We discuss the method we used for developing the ontology and give rationale for our design decisions. We provide guidelines for re-engineering schemas into ontologies and formalize their implicit semantics. In order to demonstrate the appropriateness of our ontology infrastructure, we present an exploratory environment for searching and browsing news items.

Abstract. There is a need for personalised news video retrieval due to the explosion of news materials available through broadcast and other channels. In this work we introduce a semantic based user modeling technique to capture the users' evolving information needs. Our approach exploits the Linked Open Data Cloud to capture and organise users' interests. The organised interests are used to retrieve and recommend news stories to users. The system monitors user interaction with its interface and uses this information for capturing their evolving interests in the news. New relevant materials are fetched and presented to the user based on their interests. A user-centred evaluation was conducted and the results show the promise of our approach.
