In this paper) we propose a method for text categoriza- Lion task using term weight learning. In our approach, learning is to learn true keywords from the error of clus- tering results. Parameters of term weighting are then estimated so as to maximize the true keywords and min- imize the …...

We consider the problem of assigning level numbers (weights) to hierarchically organized categories during text categorization. These levels control the ability of the categories to attract documents during the catego- rization process. The levels are adjusted to obtain a balance between recall and precision for each category. If a category's …...

It. is common in NLP that the categories into which text is classified do not have fully objective def- initions. Examples of such categories are lexical distinctions such as part-of-speech tags and word- sense distinctions, sentence level distinctions such as phrase attachment, and discourse level distinc- t.icms such as topic …...

Automatic accent inser·tion (AAI) is the problem of re-inserting accents (diacritics) into a text where they are missing. Unaccented French texts are still quite common in electronic media, as a result of a long his- tory of character encoding problems and the lack of well-established conventions for typing accented char- …...

This paper describes a method for the automatic align- ment of parallel texts at clause level. The method fea- tures statistical techniques coupled with shallow linguis- tic processing. It presupposes a parallel bilingual corpus and identifies alignments between the clauses of the source and target language sides of the corpus. …...

Most traditional approaches to anaphora resolution rely heavily on linguistic and domain knowledge. One of the disadvantages of developing a knowledge-based system, however, is that it is a very labour-intensive and timehconsuming task. This paper presents a ro- bust, knowledge-poor approach to resolving pronouns in technical manuals. This approach is …...

Miscommunication in speech recognition sys- tems is unavoidable, but a detailed character- ization of user corrections will enable speech systems to identify when a correction is taking place and to more accurately recognize the con- tent of correction utterances. In this paper we investigate the adaptations of users when they …...

In this paper, we present a framework, PRE- SENTOR, for the development and customiza- tion of hypertext presentation generators. PRE- SENTOR offers intuitive and powerful declarative languages specifying the presentation at differ- ent levels: macro-planning, micro-planning , re- alization, and formatting. PRESENTOR is im- plemented and is portable cross-platform and …...

Language modeling is to associate a sequence of words with a priori probability, which is a key part of many natural language applications such as speech recognition and statistical ma- chine translation. In this paper, we present a language modeling based on a kind of simple dependency grammar. The grammar …...

We describe novel aspects of a new natural lan- guage generator called Nitrogen. This generator has a highly flexible input representation that allows a spectrum of input from syntactic to semantic depth, and shifts' the burden of many linguistic decisions to the statistical post-processor. The generation al- gorithm is compositional, …...

This paper describes the work achieved in the first half of a 4-year cooperative research project (ARCADE), financed by AUPELF-UREF. The project is devoted to the evaluation of paral- lel text alignment techniques. In its first period ARCADE ran a competition between six sys- tems on a sentence-to-sentence alignment task …...

Treebanks, such as the Penn Treebank (PTB), offer a simple approach to obtaining a broad coverage grammar: one can simply read the grammar off the parse trees in the treebank. While such a grammar is easy to obtain, a square-root rate of growth of the rule set with corpus size …...

This paper describes a grapheme-to-phoneme conversion method using phoneme connectivity and CCV conversion rules. The method consists of mainly four modules including morpheme normalization, phrase-break detec- tion, morpheme to phoneme conversion and phoneme connectivity check. The morpheme normalization is to replace non-Korean symbols into standard Korean graphemes. The phrase-break detector …...

A term-list is a list of content words that charac- terize a consistent text or a concept. This paper presents a new method for translating a term-list by using a corpus in the target language. The method first retrieves alternative translations for each input word from a bilingual dictionary. It …...

For languages whose character set is very large and whose orthography does not require spac- ing between words, such as Japanese, tokenizing and part-of-speech tagging are often the diffi- cult parts of any morphological analysis. For practical systems to tackle this problem, un- controlled heuristics are primarily used. The use …...

Nonconcatenative constraints, such as the shuffle re- lation, are frequently employed in grammatical anal- yses of languages that have more flexible ordering of constituents than English. We show how it is pos- sible to avoid searching the large space of permuta- tions that results from a nondeterministic applica- tion of …...

In this paper we sketch an approach for Natural Language parsing. Our approach is an example-based approach, which relies mainly on examples that already parsed to their representation structure, and on the knowledge that we can get from these examples the required information to parse a new input sentence. In …...

Word processors or computers used in Japan employ Japanese input method through key- board stroke combined with Kana (phonetic) character to Kanji (ideographic, Chinese) char- acter conversion technology. The key factor of Kana-to-Kanji conversion technology is how to raise the accuracy of the conversion through the homophone processing, since we …...

In this paper I will report the result of a quan- titative analysis of the dynamics of the con- stituent elements of Japanese terminology. In Japanese technical terms, the linguistic contri- bution of morphemes greatly differ according to their types of origin. To analyse this aspect, a quantitative method is …...

In this paper we discuss the use of discourse con- text in spoken dialogue systems and argue that the knowledge of the domain, modelled with the help of dialogue topics is important in maintaining robust- ness of the system and improving recognition accu- racy of spoken utterances. We propose a …...
