This paper presents an analysis of indirect passives in Japanese in terms of event structure and qualia structure proposed in the framework of the generative lexicon (Pustejovsky 1995). On the assumption that the event structure of the indirect passive construction is based on the causative structure, the present analysis accounts …...

Cross-linguistically, there are two devices for grammar to process the focus mark [+FocusJ: the fronting of focused constituents and the insertion of a Focus Mark such as the English 'be' before focused constituents. In this mode of formulation, a comparative study of Focus and Focus-Marking in Chinese and Malay has …...

AbstractThis paper presents the French implementation of Amalgam, a machine-learned sentence realization system. It presents in some detail two of the machine-learned models employed in Amalgam and shows how linguistic intuition and knowledge can be combined with statistical techniques to improve the performance of the models....

AbstractA new variant of structured contextual grammar, which generates dependency trees, is introduced. The new generative model, called dependency contextual grammar, improves both the strong and weak generative power of contextual grammars, while being a potential candidate for the mathematical description of dependency-based syntactic models....

Different syntactic frameworks have different ways to deal with dislocation construc- tions. One major disagreement is whether or not empty categories should be assumed. Researchers have been working on this issue on the ground of "psychological reality" (of empty categories), yet have not come to an agreement. The first aim …...

The purpose of this paper is to discuss treatment of 'focus particles' in Japanese sen- tences to be incorporated in a Japanese parsing system based on the Lexical-Functional Grammar(LFG) formalism. Focus particle can follow nouns, quantifiers, verbs, other particles (postpositions) and auxiliary verbs. Thus, it is necessary for a large-scale …...

We present new results for the DSTO project on document classification of military messages. We report more specifically on the improvements to the Part-Of-Speech (POS) tagging, probabilistic process that assigns a tag to a a token, and discuss the training for Date Time Groups POS tags. A new implementation of …...

Natural language database interfaces re- quire translation knowledge to convert user questions into formal database que- ries. Previously, translation knowledge acquisition heavily depends on human specialties such as NLP, DBMS and do- main engineering, consequently under- mining domain portability. This paper attempts to semi-automatically construct translation knowledge by introducing a …...

In this paper, we present an application- oriented evaluation of three Part-of- Speech (PoS) taggers in a word sense disambiguation (WSD) system. Follow- ing the intuition that high quality input is likely to influence the final results of a complex system, we test whether the more accurate taggers also produce …...

In this paper we present an evalua- tion of overlap-based measures of sim- ilarity for sentences in the same lan- guage. The measures include syntactic and semantic information, and to that end they incorporate grammatical re- lations and flat logical forms. A full parser is required to build the above …...

From the view point of the linguistic ty- pology, Korean and Japanese have many grammatical similarities which enable it to easily construct a sense-tagged Korean corpus through an existing high-quality Japanese-to-Korean machine translation system. The sense-tagged corpus may serve as a knowledge source to extract useful clues for word sense …...

This paper1 presents our approach to the problem of single sentence summarisation. We investigate the use of Singular Value Decomposition (SVD) to guide the generation of a summary towards the theme that is the focus of the document to be summarised. In doing so, the intuition is that the generated …...

This paper presents the area under the Receiver Operating Characteristics (ROC) curve as an alternative metric for evaluating word sense disambigua- tion performance. The current met- rics – accuracy, precision and recall – while suitable for two-way classifica- tion, are shown to be inadequate when disambiguating between three or more …...

It is impossible to perform root-based searching, concordancing, and gram- mar checking in Arabic without a method to match words with roots and vice versa. A comprehensive word list is essential for incremental searching, predictive SMS messaging, and spell checking, but due to the derivational and inflectional nature of Arabic, …...

This paper describes a novel model for term frequency distributions that is derived from queuing-theory. It is compared with Poisson distributions, in terms of how well the models describe the observed distributions of terms, and it is demonstrated that a model for term frequency distributions based on queue utilisation generally …...

Interlinear text is a common presenta- tional format for linguistic information, and its creation and management have been greatly facilitated by the develop- ment of specialised software. In earlier work we developed a four-level model and corresponding formal specification for interlinear text. Here we describe a suitable XML representation for …...

This paper presents a range of methods for classifying Dutch noun countability based on either Dutch or English data. The classification is founded on transla- tional equivalences and the corpus anal- ysis of linguistic features which corre- late with particular countability classes. We show that crosslingual classification on the basis …...

If a sentence is ambiguous, it often hap- pens that the correct reading is the one which can most easily be incorporated into the discourse context. In this paper we present a simple method for imple- menting this intuition using the mecha- nism of presupposition resolution. The basic idea is …...

In dependency parsing of long sentences with fewer subjects than predicates, it is difficult to recognize which predicate governs which subject. To handle such syntactic ambiguity between subjects and predicates, this paper proposes an “S- clause” segmentation method, where an S(ubject)- clause is defined as a group of words containing …...

Currently, the most common technique for Natural Language parsing is done by using pattern matching through references to a database with the aid of grammatical structures models. But the huge variety of linguistical syntax and semantics means that accurate real time analysis is very dif- ficult. We investigate several optimisation …...
