    Doctoral Thesis
    Development of Geographic Turkish Question Answering Framework over Linked Data (GEO-TR)
    (2018) Taşar, Ceren Öcal; Komesli, Murat
    With a considerable growth of linked data, researchers focused on how to increase the availability of the semantic web technologies to provide practical usage for real life systems. Question answering systems are one of these real life systems that communicate directly with the end users, understand user intention and generate answers. End users do not want to care about any structural query language or vocabulary of the knowledge base where the point of the problem arises. In this study, a question-answering framework that converts Turkish natural language input into SPARQL queries in geographic domain is proposed. Additionally, a novel Turkish ontology which covers Chapter 6 of the geography lesson named 'Spatial Synthesis: Turkey' in secondary school in 10th grade curriculum, is developed to be used as linked data provider. Later on, a literature gap in Turkish question answering systems, which utilizes linked data in geographical domain, is addressed. Hybrid system architecture that combines natural language processing techniques with linked data technologies to generate answers is also represented. Further related research areas are also suggested. Key Words: question answering systems, linked data, ontology development, natural language processing
