Exploration of grateful dead concerts and memorabilia on the semantic Web

© 2018 CEUR-WS. All rights reserved. With the increasing importance attributed to intangible cultural heritage, of which music performance is an important part, public archive collections contain a growing proportion of audio and video material. Currently used models have only limited capabilities for their representation. This demo illustrates our proposal for a unified ontological model of live music recordings and associated tangible artefacts with a Web application for the exploration of live music events of the Grateful Dead

Active document enrichment using adaptive information extraction from text

The traditional process of document annotation for knowledge identification and extraction in the Semantic Web (SW) is complex and time consuming, as it requires manual annotation by domain experts. There is currently a strong interest in Text Mining technologies (and in particular in Human Language-based Technologies), for reducing the burden of text annotation for Knowledge Management (KM). In this poster we present Melita, an annotation interface that uses Adaptive Information Extraction from texts for reducing the burden of text annotation.peer-reviewe

Multi-strategy definition of annotation services in Melita

The definition of methodologies for automatic ontology-based document annotation is a fundamental step in the Semantic Web vision. In the near future, semantic annotation services could become as important as search engines are today. Tools for the easy and effective development of such services are therefore needed. In this paper, we present Melita, a tool for the definition and development of ontology-based annotation services. Melita goes beyond the dichotomy rule learning Vs rule writing of classic annotation systems, as it allows adopting different strategies, from annotating examples in a corpus for training a learner to rule writing and even a mixture of them. It also supports users in defining and maintaining an ontology for annotation and in delivering the annotation service. The result is a tool easy to use and flexible to different user needs.peer-reviewe

The collection is linked to existing musical and geographical resources allowing for the extraction of useful or nteresting subsets of data using additional metadata. The collection is published using a ‘layered’ approach, aggregating the original information with links and specialised analyses, and forms a valuable resource for those investigating or developing audio analysis tools and workflows

User-system cooperation in document annotation based on information extraction

The process of document annotation for the Semantic Web is complex and time consuming, as it requires a great deal of manual annotation. Information extraction from texts (IE) is a technology used by some very recent systems for reducing the burden of annotation. The integration of IE systems in annotation tools is quite a new development and there is still the necessity of thinking the impact of the IE system on the whole annotation process. In this paper we initially discuss a number of requirements for the use of IE as support for annotation. Then we present and discuss a model of interaction that addresses such issues and Melita, an annotation framework that implements a methodology for active annotation for the Semantic Web based on IE. Finally we present an experiment that quantifies the gain in using IE as support to human annotators.peer-reviewe

OntoQAV : a pipeline for visualising ontology quality

Ontological Quality has been the subject of extensive research due to the importance of ensuring that a system's underlying ontologies are t for purpose. Understanding quality problems may not be straightforward, depending on the ontologies' magnitude and complexity, the nature and extent of the problems, and the metrics used in its quality assessment. In this poster paper we present an innovative pipeline linking together a quality assessment framework (Luzzu) and an ontology visualisation framework (WebVOWL) in order to establish an ecosystem whereby knowledge engineers can assess and interactively understand quality problems within concepts and properties in ontologies.peer-reviewe
