The Automatic Abstracting Project The project is devoted to develop a new approach to automatic abstracting, which is supported by the implementation of an experimental system at the University of Udine. The system is conceived to accept input a natural language text (scientific papers, in the current application), together with the user's specifications and to produce as output a summary of the specified kind. The original contribution of the project is mostly focused on the role of forward and backward reasoning in the abstracting activity. Forward reasoning represents the aptitude to read a text, fully understand its content, reduce the text discarding superfluous information until a summary of the desired length and level of abstraction is obtained. Backward reasoning concerns the capability to capture some fragments of the text which are relevant to the abstracting task, to understand these fragments, to fill the slots of an original frame with the key terms obtained until the frame expands and becomes the final summary.
