We investigated how participation evolves in Wikidata as its editors become established members of the community. Originally conceived to support Wikipedia, Wikidata is a collaborative structured knowledge base, created and maintained by a large number of volunteers, whose data can be freely reused in other contexts. Just like in any other online social environment, understanding its contributo...

The on-line world is populated by an increasing number of knowledge-rich resources. Furthermore, there is a growing trend among authors to provide semantic markup of these resources. This presents a tantalizing prospect. Perhaps we can leverage the person-years of effort invested in building these knowledge-rich resources to create large-scale knowledge bases. The World Fact Book knowledge base...

Objective This paper describes the Precision Medicine Knowledge Base (PMKB; https://pmkb.weill.cornell.edu ), an interactive online application for collaborative editing, maintenance, and sharing of structured clinical-grade cancer mutation interpretations. Materials and Methods PMKB was built using the Ruby on Rails Web application framework. Leveraging existing standards such as the Human G...

On one hand, the proliferation of the Web has generated massive information in an unorganized way and is still growing in an accelerating pace. On the other hand, structured and queryable knowledge bases are very difficult to construct and update. Automatic knowledge base construction techniques are greatly needed to convert the rich Web information into useful knowledge bases. Besides informat...

We present an implemented approach for domainrestricted question answering from structured knowledge sources, based on robust semantic analysis in a hybrid NLP system architecture. We build on a lexicalsemantic conceptual structure for question interpretation, which is interfaced with domain-specific concepts and properties in a structured knowledge base. Question interpretation involves a limi...

Evolving out of theoretic and practical work, this paper presents the motivation and basic ideas for the construction and use of modular knowledge bases. The approach bears upon earlier work by the two authors done separately from each other. We introduce a model which attempts to merge two previous approaches while maintaining their benefits: Modules for logical knowledge bases, and ordered by...

Purpose – Aims to study the role tacit knowledge plays in shaping the knowledge base of the knowledge-intensive growing organizations using the storytelling method. Design/methodology/approach – Stories were collected from eight human resource professionals working in eight different knowledge-intensive growing organizations in New Zealand. Interviews containing loosely structured questions wer...
