A logic formalism is presented which increases the expressive power of the ID/LP format of GPSG by enlarging the inventory of ordering relations and extending the domain of their application to non-siblings. This allows a concise, modular and declarative statement of intricate word order regularities. 1....

. A grammar ,nodel for concurrent, object-ori- ented natural language l)arsing is introduced. Complete lexical distribution of grmnmatical knowledge is achieved huilding upon the head-oriented notions of valency and dependency, while inheritance mechanisms tire uscd to capture lexic;tl generalizations. The underlying concurrent computation m(xlel relies upon the actor l)aradigm. We …...

This paper describes the experiment of the English generation from interlingua by the example-based method. The generator is implemented by using English Word Dictionary ,and Concept Dictionary developed in EDR. How to construct examples lind how to define the similarities are main problems. The results of experi- ments are shown. …...

GENERATION BASED ON RHETORICAL STRUCTURE EXTRACTION Kenjl Ono, Kazuo Sumlta, Seijl Miike Research and Development Center Toshiba Corporation Komukai-Toshiba-cho 1, Saiwai-ku, Kawmsaki, 210, Japan ono@isl.rdc.toshiba.co.jp 1 ABSTRACT We have developed an automatic abstr~mt genera- tion system for Japanese expository writings based on rhetorical structure extraction. The system first extracts the …...

This paper presents PI£OVF, I¢,I"f a text planner for argumentative texts. I~I~OVI']]~II~ Inain feature is that it combines global hierarchical planning and llti- phmned organization of text with respect to local de- rivation relations in a complementary way. The former splits the task of presenting a particular pronf into subtasks …...

This paper describes the enhancements made, within a unification framework, based on typed feature structures, in order to support linking of lexical entries to their translation equivalents. To help this task we have developed an interactive environment: TGE. Several experiments, corresponding to rather "closed" semantic domains, have been developed in …...

Semantic disambiguation depends on a process of defining the appropriate knowledge context. Recent research directions suggest a eonnectionist approach which use dictionaries, but there remain problems of scale, analysis, and interpretation. IIere we focus on word disambiguation as scene selection, based on the Oxford Pictorial English Dictionary. We present a …...

We present a new softw,'u'e architecture for NLP systems made of heterogeneous components, and demonstrate an architectural prototype we have built at ATR iu the context of Speech Translation. KEYWORDS: Distributed NLP systems, Software architectures, Whiteboard....

Ira this paper I present a parser based on De- scription Logics (I)I.) for a German lll'SG-slyle fragment. The specilied parser relies mainly on the inferential capabilities of the nnderlying DL system. Given a preferential default ex- tension for DL disamhiguation is achieved by choosing the parse containing a qualitatively …...

This paper describes a syllable-based computational model for the Korean morphology. In this model, morpholovical analysis is considered as a process of candidate Generation and candidate selection. In order to increase tile performance of the system, the number of candidates is highly reduced and tim system require.s small number of …...

This paper describes a modular connection,st model of the acquisition of receptive inflectional morphology. The model takes inputs in the form of phones one at a time and outputs the associ- ated roots and infections. In its simplest version, the network consists of separate simple recurrent subnetworks for root and …...

We present a novel method for segmenting the input sentence into words and assigning parts of speech to the words. It consists of a statistical language model and an efficient two-pa~qs N-best search algorithm. The algorithm does not require delimiters between words. Thus it is suitable for written Japanese. q'he …...

Because of its simple appearance, Japanese verb inflection has never been treated seriously. In this paper we reconsider traditional lexical treatments of Japanese verb inflection, and propose a new treatment of verb inflection which uses newly- devised segmenting units. We show that our proposed treatment minimizes the number of lexical …...

In optical character recognition and coni.in- uous speech recognition of a natural language, it has been diflicult to detect error characters which are wrongly deleted and inserted. ]n <>r- der to judge three types of the errors, which are characters wrongly substituted, deleted or inserted in a Japanese "bunsetsu" and …...

This I)aper presents an implemented multi-tal)e two- level model capable of describing Semitie non-linear morphology. The computational fl'arnework behind the ettrrcnt work is motivated by [Kay 1987]; the fimnal- ism presented here is an extension to the formalism re- ported by [Puhnan art(1 Hepl)le. 1993]. The objectives of the current …...

We describe the first prototype version of TransCheck, a system for automatically detecting certain types of translation errors that is based on the notion of bi-text, or aligned corpora of translated texts. We analyse the preliminary results obtained from applying TransCheck to five lengthy samples of published translations, discuss some …...

The parsing component of previous principle-based machine translation systems are inefficient since they tend to adopt a generate-and-test paradigm. We combine the benefits of a message-passing paradigm with the benefits of a parametric approach in the implementation of a parser that avoids overgeneration and is easily ported to multiple languages. …...

We discuss some key methodological and operational aspects related to the design and development of a machine translation (MT) prototype which can be integrated in healthcare information systems. We first describe the approach adopted for collecting, formating, sampling and analyzing multilingual corpora of diagnostic expressions. The resulting generic language representation …...

We report experiments on automatic learning of an English-Chinese translation lexicon, through statistical training on a large parallel corpus. The learned vocabulary size is non- trivial at 6,517 English words averaging 2.33 Chinese translations per entry, with a manually- filtered precision of 95.1% and a single-most-probable precision of 91.2%. We …...

The increasing use of world wide networking facilities for international information exchange and service provision demands for specific applications of machine translation (MT) tools which are beyond their traditional tasks. The new areas of application of MT will have to be centered around various human-to-human communication media taking into account …...
