GorUp: An Ontology-Driven Audio Information Retrieval System that Suits the Requirements of Under-Resourced Languages
نویسندگان
چکیده
GorUp is an Information Retrieval system that provides information about the contents of audio broadcast news in Basque, Spanish, and French. Since the resources available for Basque in general, and for this task in particular, were very few, data optimization methodologies had to be applied in various phases of the development. Moreover, the agglutinative nature of Basque required the use of morphemes and other sub-word units. Additionally, some keyword spotting and semantic methods have been also applied in the system in order to retrieve information properly. In most of the cases, the methods employed during this project could suit the requirements of many under-resourced languages, and one of these techniques could be the ontology-based approach. This paper presents the system in general for Basque and emphasizes the techniques employed in order to enhance the system using a semantic ontology.

متن کاملAn Iterative approach to extract dictionaries from Wikipedia for under-resourced languages
The problem of extracting bilingual dictionaries from Wikipedia is well known and well researched. Given the structural and rich multilingual content of Wikipedia, a language independent approach is necessary for extracting dictionaries for various languages more so for under-resourced languages. In our attempt to mine dictionaries for under-resourced languages, we developed an iterative approa...
