An Approach Based on Question Answering Mechanism for Handling Unexpected Exceptions in Collaborative Design

At present, it is difficult to handle unexpected exceptions in collaborative design. Ad-hoc methods are important ones, but how to utilize the expert experience efficiently, especially, store those in structured format and not to lose any information and interact under more user-friendly interface during handling exceptions, seem a mission impossible. Aiming at those, we proposed a question answering mechanism based approach for handling unexpected exceptions in collaborative design, which have some good characteristics, 1) unexpected exception handling is treated as a question answering mechanism so as to be more user-friendly, 2) in which exception handler can use natural language to define an exception; 3) expert experience are stored in natural language, there is no information loss; 4) higher efficiency, extendability and precision. In this paper, two approaches for mining similar records are proposed, and their performance comparison is shown
