In this paper, we present an innovative chart mining technique for improving parse coverage based on partial parse outputs from precision grammars. The general approach of mining features from partial analyses is applicable to a range of lexical acquisition tasks, and is particularly suited to domain-specific lexical tuning and lexical acquisition using lowcoverage grammars. As an illustration ...

We present a first version of a filter dictionary for use in a computer-telephony text-to-speech synthesis system. The aim of the filter dictionary was to provide a lexicon that was compact, fast and had broader coverage than the standard dictionary used to create it. Correct phonemic transcriptions and lexical stress assignment were both required for a transcription to be deemed accurate. The ...

We describe the automatic acquisition of a lexicon of verb subcategorisations from a domain-specific corpus, and an evaluation of the impact this lexicon has on the performance of a “deep”, HPSG parser of English. We conducted two experiments to determine whether the empirically extracted verb stems would enhance the lexical coverage of the grammar and to see whether the automatically extracted...

the present dissertation aims to investigate four-word lexical bundles in applied linguistics research articles by iranian and internationally-published writers. the aims of this study are two-fold: first of all, attempts have been made to create a comprehensive list of the most commonly used four-word lexical bundles categorized by their type and token frequency, their structural characteristi...

Lack of proper linguistic resources is the major challenges faced by the Machine Translation system developments when dealing with the resource poor languages. In this paper, we describe effective ways to utilize the lexical resources to improve the quality of statistical machine translation. Our research on the usage of lexical resources mainly focused on two ways, such as; augmenting the para...

This paper reports on the current status and evaluation of a Finnish semantic tagger (hereafter FST), which was developed in the EU-funded Benedict Project. In this project, we have ported the Lancaster English semantic tagger (USAS) to the Finnish language. We have re-used the existing software architecture of USAS, and applied the same semantic field taxonomy developed for English to Finnish....

0 Introduction The canonical word order of English is generally taken to be SVO, where S and O are assumed to be lexical, i.e., non-pronominal (cf. Lambrecht 1987), as in (1) below. 2 (1) The news coverage showed all the, you know, the guys who didn't get hurt coming home. In the example in 1 we see that the lexical NP the news coverage is the subject of the sentence. While this sentence looks ...

Semantic role labeling (SRL) is a method for the semantic analysis of texts that adds a level of semantic abstraction on top of syntactic analysis, for instance adding semantic role labels like Agent on top of syntactic functions like Subject . SRL has been shown to benefit various natural language processing applications such as question answering, information extraction, and summarization. Au...

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

This paper describes a wide-coverage Japanese grammar based on HPSG. The aim of this work is to see the coverage and accuracy attainable using an underspecified grammar. Underspecification, allowed in a typed feature structure formalism, enables us to write down a wide-coverage grammar concisely. The grammar we have implemented consists of only 6 ID schemata, 68 lexical entries (assigned to fun...
