The Diligent argumentation framework helps capture design deliberations in ontology-engineering discussions. It makes consensus-building tasks more efficient and provides detailed guidance for nonexperts. The semantic Web envisions an infrastructure in which humans and machines seamlessly exchange information on the Web. During the discussions participants(More)
Designing an effective and sustainable citizen science (CS)project requires consideration of a great number of factors. This makes the overall process unpredictable, even when a sound, user-centred design approach is followed by an experienced team of UX designers. Moreover, when such systems are deployed, the complexity of the resulting interactions(More)
The realization of the Semantic Web as a linked machine readable Web of data depends on the availability of authoring tools that enable ordinary Web users (i.e. non-experts w.r.t. Web technologies) to create and publish semantic data. In this paper, we introduce the “One Click Annotator” for enriching texts with RDFa annotations and linking resources(More)
The workshop on Usage Analysis and the Web of Data (USEWOD2011) was the first workshop in the field to investigate combinations of usage data with semantics and the Web of Data. Questions the workshop aims to address are for example: How can semantics help in understanding usage data, how can semantic information be derived from usage data, and how can we(More)
We conducted a quantitative analysis of ten citizen science projects hosted on the Zooniverse platform, using a data set of over 50 million activity records and more than 250, 000 users, collected between December 2010 and July 2013. We examined the level of participation of users in Zooniverse discussion forums in relation to their contributions toward the(More)
Weaving the Semantic Web the research community is working on publishing publicly available data sources as RDF data on the Web. Well-known costand process-oriented problems of ontology engineering hinder the employment of ontologies as a flexible, scalable, and cost-effective means for integrating data in corporate contexts. We propose an innovative(More)
Ontologies are an appropriate means to represent knowledge on the Web. Research on ontology engineering methodologies has come from describing the scratch development of ontologies and reached practices for an integrative lifecycle support. The ontology engineering discipline has changed from an individual art towards a collaborative and distributed process(More)
Online citizen science [Silvertown 2009] can be seen as a form of collective intelligence Lévy [1997] and Woolley et al. [2010] in which the wisdom of the crowd is applied to the Web to advance scientific knowledge [Prestopnik and Crowston 2012] Thus far, online citizen science projects [Bonney et al. 2009; Gray et al. 2012] have applied millions of(More)
In this concept paper, we outline our working plan for the next phase of the Corporate Semantic Web project. The plan covers the period from March 2009 to March 2010. Corporate ontology engineering will improve the facilitation of agile ontology engineering to lessen the costs of ontology development and, especially, maintenance. Corporate semantic(More)
