Abstract
The major purpose of this research is to discover the information retrieval related characteristics of the domain-specifics text documents during the development of the IR models for architecture, engineering and construction domain. The authors proposed a set of research progress to finding the solution to improve the retrieval performance for domain-specific documents, including: a. preparing the testing reference collection to provide a standard platform for evaluating the developed IR models; b. propose a methodology to extract the domain ontology from domain handbooks, and to reduce the work load for participating experts while editing and revising the ontology; c. propose a novel passage retrieval model, named “OntoPassage”, it takes domain ontology to producing concept-oriented passages that could improve the retrieval performance of the domain-specific IR. In the thesis, the research objectives, problems faced and proposed solutions of each progress were discussed separated in independent chapters. The experiment results showed the OntoPassage could highly improve the retrieval performance. OntoPassage retrieval system also demonstrates the potential success of learning and sharing the domain knowledge by using the concept-oriented retrieval scenario.
