GE-CMU: description of the TIPSTER/SHOGUN system as used for MUC-4

The GE-CMU team is developing the TIPSTER/SHOGUN system under the governmentsponsored TIPSTER program, which aims to advance coverage, accuracy, and portability in tex t interpretation. The system will soon be tested on Japanese and English news stories in two new domains. MUC-4 served as the first substantial test of the combined system. Because th e SHOGUN system takes advantage of most of .the components of the GE NLTooLsET except for the parser, this paper supplements the NLTOOLSET system description by explaining th e relationship between the two systems and comparing their performance on the examples from MUC-4. INTRODUCTIO N Work on the GE-CMU TIPSTER-SHOGUN system began in the fall of 1991 . The first stage of the project involved integrating the resources and algorithms of the existing GE and CMU systems, in order that the combined team could effectively explore new data extraction methods . This integration was barely complete d in time for MUC-4: There are still some loose ...
