Automatic part of speech tagging is an area of natural language processing where statistical techniques have been more successful than rule- based methods. In this paper, we present a sim- ple rule-based part of speech tagger which au- tomatically acquires its rules and tags with ac- curacy comparable to stochastic …...

The paper reports on a new approach to automatic generation of back-of-book indexes for Chinese books. Parsing on the level of complete sentential analysis is avoided because of the inefficiency and unavailability of a Chinese Grammar with enough coverage. Instead, fundamental analysis particular to Chinese text called word segmentation is …...

I1. is often assumed that when natural language processing meets the real world, the ideal of aiming for complete and correct interpretations has to be abandoned. However, our experience with TACITUS; especially in the MUC-3 eval- uation, has shown that. principled techniques fox' syntactic and pragmatic analysis can be bolstered …...

This paper presents a system which detects and corrects morpho-syntactic errors in Dutch texts. It includes a spelling corrector and a shift-reduce parser for Augmented Context-free Grammars. The spelling corrector is based on trigram and triphone analysis. The parser is an extension of the well-known Tomita algorithm (Tomita, 1986). The …...

The real difficulty in development of practical NLP systems comes from the fact that we do not have effective means for gathering "knowl- edge". In this paper, we propose an algorithm which acquires automatically knowledge of se- mantic collocations among "words" from sam- ple corpora. The algorithm proposed in this …...

When implementing computational lexicons it is important to keep in mind the texts that a NLP system must deal with. Words relate to each other in many different, often queer, ways: this information is rarely found in dictionaries, and it is quite hard to be invented a priori, despite the …...

We describe the lexical knowledge base sys- tem (LKB) which has been designed and im- plemented as part of the ACQUILEX project 1 to allow the representation of multilinguM syn- tactic and semantic information extracted from machine readable dictionaries (MRDs), in such a way that it is usable by natural …...

This paper is concerned with the question of how to extract lexical knowledge from Machine- Readable Dictionaries (MRDs) within a lexi- cal database which integrates a lexicon devel- opment environment. Our long term objective is the creation of a large lexical knowledge base using semiautomatic techniques to recover syn- tactic …...

In our current research into the design of cognitively well-mo- tivated interfaces relying primarily on the display of graphical information, we have observed that graphical information alone does not provide sufficient support to users particu- larly when situations arise that do not simply conform to the users' expectations. This can …...

The Intelligent Documentation Advisory Sys- tem generates on-line documentation and help messages from a domain knowledge base, using natural-language (NL) generation techniques. This paper gives an overview of IDAS, with par- ticular emphasis on: (1) its architecture and the types of questions it is capable of answering; (2) its KR …...

We present a localisation component that sup- ports the generation of cross-modal deictic ex- pressions in the knowledge-based presentation system WIP. We deal with relative localisations (e.g., "The object to the left, of object X."), absolute localisations (e.g., "The object in the upl)er left part of the l)icture.") and corner …...

This paper describes the approach followed in the development of the linguistic proces- sor of the continuous speech dialog system im- plemented at our labs. The application sce- nario (voice-based information retrieval ser- vice over the telephone) poses severe specifi- cations to the system: it has to be speaker- independent, …...

In this paper, we concern ourselves with an applica- tion of text-to-speech for speech-impaired, deaf, and hard of hearing people. The application is unusual because it requires real-time synthesis of unedited, spontaneously generated conversational texts transmitted via a Telecommunications Device for the Deaf (TDD). We describe a parser that we …...

Multilevel semantics has been proposed as a powerful architecture for semantic analysis. We propose a methodology that, while maintaining the generality of the multilevel approach, is able to establish formal constraints over the possible ways to organize the level hierarchy. More precisely, we propose a "strong" version of the multilevel …...

Weather reports are created in various modes -- natural language text, specialized language text, tables and maps. The system presented allows the user to define his needs of weather information and requirements on the form of presentation. The system analyzes a dataset obtained through spe- cific procedures of forecasting or …...

The paper describes a principled approach to the problem of deriving database queries from logical forms produced by a general NL in- terface. Our method attempts to construct a database query and a set of plausible assump- tions, such that the logical form is equivalent to the query given the …...

underlying predication. Predicates and predications make no reference whatsoever to the surface forms of expressions. Predications are related to surface orderings by means of expression rules. These constitute the nearest thing FG has to a syntactic component. Functional Grammar and the Computer consists of six sections containing a total of …...

AbstractWe present JANUS, a speech-to-speech translation system that utilizes diverse processing strategies including connectionist learning, traditional AI knowledge representation approaches, dynamic programming, and stochastic techniques. JANUS translates continuously spoken English utterances into Japanese and German speech utterances. The overall system performance on a corpus of conference registration conversations is 87%. …...

AbstractAll human languages are open and complex communication systems. No machine translation system will ever be able to automatically translate all possible sentences from one language to another in high quality. One way to combat complexity and openness of language translation is to decompose the task into well-defined sequential subtasks …...

AbstractRecently, several types of Japanese to English MT (machine translation) systems have been developed, but prior to using such systems, they have required a pre-editing process of re-writing the original text into Japanese that could be easily translated. For communication of translated information requiring speed in dissemination, application of these …...
