The Walkthrough Example

The text of the system-walkthrough is given in an appendix to this volume. We were dismayed to see that our system did not produce a template in response to the walkthrough text. Closer inspection, however, revealed that the system had in fact produced a reasonable analysis for this text, but the analysis was discarded by the POST PROCESSOR because it failed a basic consistency check: the joint venture company had to be distinct from all of its parent entities. Experience has shown that a failure to satisfy this condition usually arises due to a failure in the merging process, and it turns out that the score is usually improved by discarding what is likely to be a spurious template. Unfortunately in this case the strategy resulted in discarding basically correct information. We turned off the filter, and reran the example, producing the output listed in Appendix 1.
