Text Skimming as a Part in Paper Document Understanding
Rainer Bleisinger; Klaus-Peter GoresZusammenfassung
With respect to the usually proposed three working phases of a predictor -- start, discrimination, and instan-tiation -- the following differences are remarkable. The starting problem of text skimming is solved by applying specialized substantiators for classifying a business letter into message types. In order to select appropriate expectations within the message type hypotheses a twofold discrimination is performed. A coarse discrimination reduces the number of message type alternatives, and a fine discrimination chooses one expectation within one or a few previously selected message types. According to the expectation selected substantiators are activated. Several rules are applied both for the verification of the substantiator results and for error recovery if the results are insufficient.
