Multi-Ontology Learning: Crossing the Boundaries of Domains and Languages
Zusammenfassung der Projektergebnisse
The main focus of the MULTIPLA project was on the development of methods that allow to generate, to improve and to apply multilingual knowledge structures, ontologies in particular. One important goal was to develop methods that can exploit these multilingual knowledge structures for the task of cross-lingual information retrieval. Several achievements have been reached in the MULTIPLA project. First, we showed that user-generated content from popular knowledge and community portals can be used as multilingual resource. This allows to exploit the growing Web 2.0 consisting of millions of contributions by users from various linguistic regions. As an important contribution, we developed new approaches to build knowledge structures from these multilingual resources and we showed the actual benefit of exploiting such structures in the conlext of multilingual search and retrieval tasks. Second, we introduced several methods to improve the quality of multilingual resources. This includes approaches to ontology alignment and to ontology learning. In this line of research, we also investigated in analyzing the quality of existing Web 2.0 datasets. Third, research investigations in the field of Web mining have emphasized the role of multi-aspect content analysis for knowledge extraction tasks from Social Media. In the context of the MULTIPLA project we organized two international workshops on multilingual expert search and one on detecting and exploiting cultural diversity on the Social Web. Further, we established a multilingual retrieval challenge for multilingual expert search on a Web 2.0 dataset. These successful events were part of the project dissemination work and showed the interest of other groups on the research in MULTIPLA. The research results from the MULTIPLA project have been applied in several other projects at AIFB and WeST, such as RENDER., Active, Live+Gov, and SocialSensor. This shows that the foundational research results that were achieved in this project can be exploited in different application scenarios.
