RESUMO

The Building Industry has been adopting several technologies in the last years for improving its performance, including those from the Information Technology (IT). Some of the main objectives of IT in this sector are to integrate and to add value to processes, as well as to help in enterprise management. In this sense, along with the consolidation of the Internet, the so-called project extranets were developed for process management and document archival. With these systems it is possible to integrate all the different teams involved with the building construction processes, offering each user a large amount of information. The purpose of this work is to devise an expert tool to help in the information retrieval from building documents stored in project extranets. The searching engines available in current extranets are conventional, featuring only keyword search. These mechanisms can retrieve many irrelevant documents upon a request. This is due to the generic nature and the non-contextualization of these tools. The subject matter of the documents in a project extranet is restricted (Building Construction). The proposed tool aims to optimize the user query terms and to rank retrieved documents according to their relevance. The document search and ranking algorithms of this system are based on building construction domain knowledge for improving retrieval efficacy. The obtained results show large improvements on the system’s precision and recall parameters when compared to a standard search mechanism.
