Thompson Conference Center, University of Texas at Austin Morning 8:30 A.M. - 12:30 P.M. 8:30 12:30 INTRODUCTION TO NATURAL LANGUAGE PROCESSING James Allen, University of Rochester ABSTRACT This tutorial will cover the basic concepts underlying the construction of natural language processing systems. These include basic parsing techniques, semantic interpretation and the representation of sentence meaning, as well as knowledge representation and techniques for understanding natural language in context. In particular, the topics to be addressed in detail will include augmented transition networks (ATNs), augmented context-free grammars, the representation of lexical meaning, especially looking at case-grammar based representations, and the interpretation of pronouns and ellipsis. In addition, there will be an overview of knowledge representation, including semantic networks, frame-based systems, and logic, and the use of general world knowledge in language understanding, including scripts and plans. Given the large range of issues and techniques, an emphasis will be placed on those aspects relevant to existing practical natural language systems, such as interfaces to database systems. The remaining issues will be more quickly surveyed to give the attendee an idea of what techniques will become important in the next generation of natural language systems. The lecture notes will include an extensive bibliography of work in each area. INTENDED AUDIENCE This tutorial is aimed at people who are interested in learning the fundamental techniques and ideas relevant to natural language processing. It will be useful to managers who want an overview of the field, to programmers starting research and development in the natural language area, and to researchers in related disciplines such as linguistics who want a survey of the computational approaches to language. BIOGRAPHICAL SKETCH Dr. James Allen is an Associate Professor and Chairman of the Computer Science Department at the University of Rochester. He is editor of the journal Computational Linguistics and author of the book Natural Language Understanding, published in 1987. In 1984, he received a five-year Presidential Young Investigator award for his research in Artificial Intelligence. 8:30 12:30 MACHINE-READABLE DICTIONARIES: A COMPUTATIONAL LINGUISTICS PERSPECTIVE Branimir Boguraev, Cambridge University, and Beth Levin, Northwestern University ABSTRACT The lexical information contained explicitly and implicitly in machine-readable dictionaries (MRDs) can support a wide range of activities in computational linguistics, both of theoretical interest and of practical importance. This tutorial falls into two parts. The first part will focus on some characteristics of raw lexical data in electronic sources, which make MRDs particularly relevant to natural language processing applications. The second part will discuss how theoretical linguistic research into the lexicon can enhance the contribution of MRDs to applied computational linguistics. The first half will discuss issues concerning the placement of rich lexical resources on-line; raise questions related to the suitability, and ultimately the utility, of MRDs for automatic natural language processing; outline a methodology aimed at extracting maximally usable subsets of the dictionary with minimal introduction of errors; and present ways in which specific use can be made of the lexical data for the construction of practical language processing systems with substantial coverage. The second half of the tutorial will review current theoretical linguistic research on the lexicon, emphasizing proposals concerning the nature of lexical representation and lexical organization. This overview will provide the context for an examination of how the results of this research can be brought to bear on the problem of extracting syntactic and semantic information encoded in dictionary entries, but not overtly signaled to the dictionary user. INTENDED AUDIENCE This tutorial presupposes some familiarity with work in both computational and theoretical linguistics. It is aimed at researchers in natural language processing and theoretical linguists who want to take advantage of the resources available in MRDs for both applied and theoretical purposes. The issues of providing substantial lexical coverage and system transportability are addressed, thus making this tutorial of particular relevance to those concerned with the automatic acquisition, on a large scale and in a flexible format, of phonological, syntactic, and semantic information for nlp systems. BIOGRAPHICAL SKETCHES Dr. Branimir Boguraev is an SERC (UK Science & Engineering Research Council) Advanced Research Fellow at the University of Cambridge. He has been with the Computer Laboratory since 1975, and completed a doctoral thesis in natural language processing there in 1979. Recently he has been involved in the development of computational tools for natural language processing, funded by grants awarded by the UK Alvey Programme in Information Technology. Dr. Beth Levin is an Assistant Professor in the Department of Linguistics, Northwestern University, Evanston, IL. She was a System Development Foundation Research Fellow at the MIT Center for Cognitive Science from 1983-1987 where she assumed major responsibility for directing the MIT Lexicon Project. She received her Ph.D. in Electrical Engineering and Computer Science from MIT in June 1983. 8:30 12:30 SPOKEN LANGUAGE SYSTEMS: PAST, PRESENT, AND FUTURE Salim Roucos, BBN Laboratories, Inc. ABSTRACT: This tutorial will present the issues in developing spoken language systems for natural speech communication between a person and a machine. In particular, the performance of complex tasks using large vocabularies and unrestricted sentence structures will be examined. The first Advanced Research Projects Agency (ARPA) Speech Understanding Research project during the seventies will be reviewed, and then the current state-of-the-art in continuous speech recognition and natural language processing will be described. Finally, the types of spoken language systems' capabilities expected to be developed during the next two to three years will be presented. The technical issues that will be covered include acoustic-phonetic modeling, syntax, semantics, plan recognition and discourse, and the issues for integrating these knowledge sources for speech understanding. In addition, computational requirements for real-time understanding, and performance evaluation methodology will be described. Some of the human factors of speech understanding in the context of performing interactive tasks using an integrated interface will also be discussed. INTENDED AUDIENCE: This tutorial is aimed at technical managers, product developers, and technical staff interested in learning about spoken language systems and their potential applications. No expertise in either speech or natural language will be assumed in introducing the technical details in the tutorial. BIOGRAPHICAL SKETCH: Dr. Salim Roucos has worked for seven years at BBN Laboratories in speech processing such as continuous speech recognition, speaker recognition, and speech compression. More recently, he has been the principal investigator on integrating speech recognition and natural language understanding for developing a spoken language system. His areas of interest are statistical pattern recognition and language modeling. Dr. Roucos is chairman of the Digital Signal Processing committee of the IEEE ASSP society. Afternoon 1:30 P.M. - 5:30 P.M. 1:30 5:30 THE TECHNOLOGY OF NATURAL LANGUAGE INTERFACES Carole D. Hafner, Northeastern University ABSTRACT This tutorial will describe the development of natural language processing from a research topic into a commercial technology. This will include a description of some key research projects of the 1970's and early 1980's which developed methods for building natural language query interfaces, initially restricted to just one database, and later made "transportable" to many different applications. The further development of this technology into commercial software products will be discussed and illustrated by a survey of several current products, including both micro-computer NL systems and those offered on higher-performance machines. The qualities a user should look for in a NL interface will be considered, both in terms of linguistic capabilities and general ease of use. Finally, some of the remaining "hard problems" that current technology has not yet solved in a satisfactory way will be discussed. INTENDED AUDIENCE This tutorial is aimed at people who are not well acquainted with natural language interfaces and who would like to learn about 1) the capabilities of current systems, and 2) the technology that underlies these capabilities. BIOGRAPHICAL SKETCH Dr. Carole D. Hafner is Associate Professor of Computer Science at Northeastern University. After receiving her Ph.D. in Computer and Communication Sciences from the University of Michigan, she spent several years as a Staff Scientist at General Motors Research Laboratories working on the development of a natural language interface to databases. 1:30 5:30 THE ROLE OF LOGIC IN REPRESENTING MEANING AND KNOWLEDGE Robert C. Moore, SRI International ABSTRACT This tutorial will survey the use of logic to represent the meaning of utterances and the extra-linguistic knowledge needed to produce and interpret utterances in natural-language processing systems. Problems to be discussed in meaning representation include quantification, propositional attitudes, comparatives, mass terms and plurals, tense and aspect, and event sentences and adverbials. Logic-based methods (unification) for systematic specification of the correspondence between syntax and semantics in natural language processing systems will also be touched on. In the discussion of the representation of extra-linguistic knowledge, special attention will be devoted to the role played by knowledge of speakers' and hearers' mental states (particularly their knowledge and beliefs) in the generation and interpretation of utterances and logical formalisms for representing and reasoning about knowledge of those states. INTENDED AUDIENCE This tutorial is aimed at implementors of natural-language processing systems and others interested in logical approaches to the problems of meaning representation and knowledge representation in such systems. BIOGRAPHICAL SKETCH Dr. Robert C. Moore is a staff scientist in the Artificial Intelligence Center of SRI International. Since joining SRI in 1977, Dr. Moore has carried out research on natural-language processing, knowledge representation, automatic deduction, and nonmonotonic reasoning. In 1986-87 he was the first director of SRI's Computer Science Research Centre in Cambridge, England. Dr. Moore received his PhD from MIT in 1979. 1:30 5:30 MACHINE TRANSLATION Sergei Nirenburg, Carnegie Mellon University ABSTRACT The central problems faced by a Machine Translation (MT) research project are 1) the design and implementation of automatic natural language analyzers and generators that manipulate morphological, syntactic, semantic and pragmatic knowledge; and 2) the design, acquisition and maintenance of dictionaries and grammars. Since a short-term goal (or even medium term goal) of building a system that performs fully automated machine translation of unconstrained text is not feasible, an MT project must carefully constrain its objectives. This tutorial will describe the knowledge and processing requirements for an MT system. It will present and analyze the set of design choices for MT projects including distinguishing features such as long-term/short-term, academic/commercial, fully/partially automated, direct/transfer/interlingua, pre-/post-/interactive editing. The knowledge acquisition needs of an MT system, with an emphasis on interactive knowledge acquisition tools that facilitate the task of compiling the various dictionaries for an MT system will be discussed. In addition, expectations, possibilities and prospects for immediate application of machine translation technology will be considered. Finally, a brief survey of MT research and development work around the world will be presented. INTENDED AUDIENCE This tutorial is aimed at at a general audience that could include both students looking for an application area and testbed for their ideas in natural language processing and people contemplating starting an MT or machine-aided translation project. BIOGRAPHICAL SKETCH Dr. Sergei Nirenburg, Research Scientist at the Center for Machine Translation at Carnegie-Mellon University, holds an M.Sc. in Computational Linguistics from Kharkov State University, USSR, and a Ph.D. in Linguistics from the Hebrew University of Jerusalem, Israel. He has published in the fields of parsing, generation, machine translation, knowledge representation and acquisition, and planning. Dr. Nirenburg is Editor of the journal Computers and Translation.
