AdaptIE Using Domain Language concept to enable Domain Experts in Modeling of Information Extraction Plans

Implementing domain specific Information Extraction (IE) technologies to retrieve structured information from unstructured data is a challenging and complex task. It requires both: IE expertise and domain knowledge, provided by a domain expert who is aware of, e.g., the text corpus specifics and entities of interest. While the IE expert role is addressed by several approaches, less has been done in enabling domain experts in the process of IE development. Our approach targets this issue. We provide a base platform for collaboration of experts ’ through IE modeling languages. We provide each of the experts with an IE language that is adapted to their respective expertise. IE experts leverage a fine grained view and domain experts can use a coarse grain view on IE plan. We use Model Driven Architecture concept to enable transition among the languages and a model of algebraic IE framework. To prove applicability of our approach we realized AdaptIE and demonstrate it in a real world scenario for the SAP Community Network.
