FERRET is a full text, conceptual information retrieval system that uses a partial understanding of its texts to provide greater precision and recall performance than keyword ,search techniques, It uses a machine-readable dictionary to augment its lexical knowledge and a variant of genetic learning to extend its script database. Comparison of FERRET's… (More)
The Turing Test was proposed by Alan Turing in 1950; he called it the Imitation Game. In 1991 Hu Loebner prize competition, offering a f h Loebner started the 100,000 prize to the author of the first computer program to pass an unrestricted Turing test. Annual competitions are held each year with smaller prizes for the best program on a restricted Turing… (More)
The inevitable proliferation of expert systems underscores the need for robust, friendly interfaces requiring minimal user training. The objective of the XCALIBUR project is to meet this need by providing natural comprehension and generation in the context of a focused mixed-initiative dialog. The XCALIBUR architecture is discussed, including its three… (More)
Abstrac t This paper describes the GE-CMU TIPSTER/SHOGUN system as configured for the TIP-STER 24-month (MUC-5) benchmark, and gives details of the system's performance on the selected Japanese and English texts. The SHOGUN system is a distillation of some of the key ideas that emerged from previous benchmarks and experiments, emphasizing a simple… (More)
This paper presents a semantically oriented, rule based method for single sentence text generation and discusses its implementation in the Kafka generator. This generator is part of the XCALIBUR natural language interface developed at CMU to provide natural language facilities for a wide range of expert systems and data bases. Kafka takes as input the… (More)
Abstrac t The GE-CMU team is developing the TIPSTER/SHOGUN system under the government-sponsored 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 tw o new domains. MUC-4 served as the first substantial test of the combined system.… (More)
Abstrac t This paper reports on the joint GE-CMU Tipster SHOGUN customization effort for MUC-4 , and analyzes the results of the TST3 and TST4 runs in comparison with the GE system .
A number of projects at the Carnegie-Mellon University Computer Science Department address issues in Natural Language Processing. Since several of these projects share rescarchers and a similar view of the world, we have listed them in a single summary. Our general interests are in robust man-machine interfaces and the modelling of human dialogs.
