This paper presents an overview of the TIPSTER/SHOGUN project, the major results, and the SHOGUN data extraction system. TIP-STER/SHOGUN was a joint effort of Management and Data Systems (formerly GE Aerospace), part of the ARPA TIPSTER Text program. Two of the main technical thrusts of the project were: (1) the development of a model of finite-state(More)
PHRED (PHRasal English Diction is a natural language generator designed for use in a variety of domains. It was constructed to share a knowledge base with PHRAN (PHRasal ANalyzer) as part of a real-time user-friendly interface. The knowledge base consists of pattern-concept pairs, i.e., associations between linguistic structures and conceptual templates.(More)
Ordinarily, one thinks of the problem of natural language understanding as one of making a single, left-to-right pass through an input, producing a progressively refined and detailed interpretation. In text interpretation, however, the constraints of strict left-to-right processing are an encumbrance. Multi-pass methods , especially by interpreting words(More)
To understand the roles of secretory peptides in developmental signaling, we have studied Drosophila mutant for the gene peptidylglycine alpha-hydroxylating monooxygenase (PHM). PHM is the rate-limiting enzyme for C-terminal alpha-amidation, a specific and necessary modification of secretory peptides. In insects, more than 90% of known or predicted(More)
Recent work in text analysis has suggested that data on words that frequently occur together reveal important information about text content. Co-occurrence relations can serve two main purposes in language processing. First, the statistics of co-occurrence have been shown to produce accurate results in syntactic analysis. Second, the way that words appear(More)
This is the first and final collection of a noteworthy set of research papers, which is both historical and timely. PLNLP, the Programming Language for Natural Language Processing, which emerged at IBM's Thomas J. Watson Research Center in Yorktown Heights about 15 years ago, is ostensibly the glue that holds the volume's 22 chapters together. But it is as(More)
To learn about construction of the adult nervous system, we studied the differentiation of imaginal neurons in the Drosophila visual system. OL2-A and OL3 are tangential neurons that display dFMRFa neuropeptide gene expression in adults but not in larvae. The two large OL2-A neurons are generated near the end of the embryonic period and already show(More)
