  <description><![CDATA[Logic based programming systems have enjoyed increasing popularity in applied AI work in the last few years. One of the contributions that the logic programming paradigm has made to computational linguistics is the Definite Clause Grammar (DCG). An excellent introduction to this formalism can be found in [9] in which the authors present the formalism and make a detailed comparison to Augmented Transition Networks (ATN) as a means of both specifying a language and parsing sentences in that lan...]]></description>

  <description><![CDATA[BUP is a bottom-up syntactic analyzer that can be used in several ways: as a simple bottom-up parser for context-free languages, as a bottom-up parser for extended-phrase structure grammars (equivalent in power to an ATN), or as a transducer for either. BUP accepts a grammar and lexicon specified as rules. It will then analyze input strings according to those rules, recording its findings in a chart and producing all analyses in parallel. Rules can be displayed, added, or deleted incrementall...]]></description>

  <description><![CDATA[Logic-based programming systems have enjoyed increasing popularity in applied AI work in the last few years. One of the contributions to Computational Linguistics made by the Logic Programming Paradigm has been the Definite Clause Grammar. In comparing DCGs with previous parsing mechanisms such as ATNs, certain clear advantages are seen. We feel that the most important of these advantages are due to the use of Logical Variables with Unification as the fundamental operation on them. To illustr...]]></description>

  <description><![CDATA[This chapter discusses the design and implementation of the ATN interpreter and compiler used in the PLANES system ([Walt75], [Walt76] and [Walt78]). This system, developed at the University of Illinois in the mid 1970’s, is an interactive question-answering system which answers questions concerning a large database of aircraft maintenance information. The intended scope of the PLANES system is to answer such questions as:

How many Skyhawks required engine repairs in 1973?

  <description><![CDATA[Augmented Transition Networks have become a popular and effective tool for constructing natural language understanding systems. Our own system, PLANES, is based on a large “semantic grammar” which is implemented as an ATN network. In developing our system, we were frustrated by numerous problems and shortcomings in the basic ATN formalism. Consequently, we have augmented and extended the model to overcome some of these problems. We have also developed an optimizing compiler for ATN networ...]]></description>

  <description><![CDATA[This thesis is intended to both document the implementation of the ATN Augmented Transition Networks interpreter and compiler and to serve as a manual for anyone interested in using it. Chapter II gives a brief description of ATNs and discusses some of the high-level design considerations. Chapter III describes the interpreter and the auxiliary functions available to the user in some detail. Chapter IV presents the compiler which can translate ATN networks into LISP code or machine language i...]]></description>

  <description><![CDATA[A prime obstacle for non-technical people who wish to use computers has been the need to either learn a special language for communicating with the machine or communicate via an intermediary. We feel that the time is ripe for computers to be equipped for natural language systems that can be used by persons who are not trained in any special computer language. In order for such systems to be of value to a casual user, the systems must tolerate simple errors, must embody a degree of "common sen...]]></description>
