From Keywords to Ontologies: An autonomous agent mapping traditional keyword related data to ontologies on semantic web
Abstract: Mapping an old database originally designed for keyword searching to ontology terms on semantic web was studied in this paper. Specifically, a database containing biological experiment images together with relevant data was used in this project. In order to meet the annotation challenge, a multiagent system was designed and then implemented. Four annotation methods were created. In order to check the quality of annotations as well as make a comparison of the four annotation methods, we performed user evaluations to make a comparison of the four annotation methods. Several professional researchers who used to work with the database were involved in evaluations where the annotation terms found by the agent were exposed to the subjects who were requested to select the most appropriate terms. The results of user evaluations were discussed. With the first results, some improvements and modifications were applied to the agent. At the end, suggestions for future works were listed.

Peer Production in the Physical World
Abstract: Traditional views on organization consider top-down structures and processes as fundamental requirements for the successful realization of group efforts. This view has however been changing over the last decades. The emergence of the Internet brought with it radically different approaches to collaboration. Online information and communication technologies gave rise to new types of organizations characterized by their bottom-up, self-organizing and self-regulating properties. Our research looks at this topic from the perspective of grassroots communities and investigates whether peer production could extend beyond the online spectrum. Furthermore we investigate if there are any organizational innovations happening around grassroots communities that allow them to come closer to becoming self-sufficient entities, and to what extent they resemble online organizations.
