The experiment performed as part of the MUC-3 evaluation was aimed at determinin g whether linguistic phenomena can be tested in isolation for state-of-the-art dat a extraction . Although not all of the methods of data extraction used by the participants in MUC-3 directly process linguistic phenomena, the methods are dealing with those phenomena in some manner because they are present in the input . Phenomena testing in MUC-3 is testing according to the characteristics of th e messages rather than characteristics of the systems processing those messages .", |

The systems scored similarly on the slots filled from phrase s containing appositives and sentences containing appositives suggesting that information from sentences could be used to test phenomena . Because the processing o f apposition can affect the processing of the entire sentence, the parallel results i n these scores further suggests that the phenomenon of apposition is being isolated . The systems scored markedly higher on the simpler appositives as opposed to th e more complex ones . These results are perhaps the strongest evidence that it is possible to isolate the phenomenon of apposition by scoring slot fills . The system s scored differently on the postposed and preposed appositives . It would be interestin g to look at the methods employed by each system with respect to these classes o f appositives . It was predicted that neither class would be clearly easier . The fact that this prediction was correct provides strong support for the claim that apposition i s being isolated . The systems scored lower on their responses to the messages where simple sentences were substituted for appositives . The effect on the scores, althoug h unexpected, still supports the isolatability of apposition . In some of the more welldefined trends, the anomalies noticed are often for the lower scoring systems . However, the systems are scoring highly enough overall at this stage of developmen t for the phenomena scores to be meaningful . In conclusion, there are strong indications that the phenomenon of apposition has been isolated by the testing and tha t performance on apposition can be scored using the MUC-3 scoring system .", |
