This research investigates Chinese intermediate EFL learners' errors in their writing at lexical, syntactical and textual levels based on the theories and researches of vocabulary recognition, error analysis and cohesion in the domain of discourse analysis. Both statistic and linguistic analysis were made to shed light on the learners' most incompetent aspects of the target language. The results show that the learners' greatest difficulty in their writing is grammar, which is followed by use of words and textual cohesion. It is concluded that different linguistic levels display different features of errors and therefore require different treatments. 展开更多

This paper presents two different algorithms that derive the cohesion structure in the form of lexical chains from two kinds of language resources HowNet and TongYiCiCiLin. The re-search that connects the cohesion structure of a text to the derivation of its summary is displayed. A novel model of automatic text summarization is devised,based on the data provided by lexical chains from original texts. Moreover,the construction rules of lexical chains are modified accord-ing to characteristics of the knowledge database in order to be more suitable for Chinese summa-rization. Evaluation results show that high quality indicative summaries are produced from Chi-nese texts. 展开更多

The Information Technology (IT) developments have changed the use of Healthcare terminologies from paper-based mortality statistics with the WHO international classifications of diseases (ICD) to the IT-based morbidity implementations for instance for Casemix-based healthcare funding and managing systems. This higher level of granularity is worldwide spread under the umbrella of several national modifications named ICD10 XM. These developments have met the increased use of the International Clinical Reference Terminology named SNOMED. When the updating of WHO ICD10 to WHO ICD11 was decided a merging was envisaged and a WHO SNOMED CT common work proposed a methodology to create a common formal ontology between the 11th version of the WHO International Classification of Diseases and Health Problems (ICD) and the most used in the world clinical terminology named Systematized Nomenclature of Human and Veterinary Medicine - Clinical Terms (SCT). The present work follows this unachieved work and aims to develop a SNOMED-based formal ontology for ICD11 chapter 1 using the textual definitions of ICD11 codes which is a completely new character of ICD and the ontology tools provided by SCT in the publicly available SNOMED Browser. There are two key results: the lexical alignment is complete and the ontology alignment is incomplete with the validated SNOMED concept model can be completed with not yet validated attributes and values of the SNOMED Compositional Grammar. The work opens a new era for the seamless use of both international terminologies for morbidity for instance for DRG/Casemix and clinical management use. The main limitation is that it is restricted to 1 out of 26 chapters of ICD11. 展开更多

This is not only because of the difference in language structures between their native language and the target language but also because of many other factors. In this thesis, we will focus on the description e and explanation of the interference and analyses of errors made by Chines students in their EFL learning. Analysis will be done at three linguistic levels: phonological, morphological and lexical. 展开更多

许多从传统观念看没有任何隐喻特征的话语表达方式,如词汇、短语等,在概念层上是与概念隐喻紧密相关的。在话语理解过程中,隐喻思维在词汇、篇章和文化三个层面依据话语信息构建意义,因此隐喻的认知过程是话语理解的关键环节。

Health communication is critical component of effective health delivery. While there are studies on the readability Patient Information Leaflets (PILs) around the world, so far, there is only one Ghanaian study that explored the language of patient information leaflets for malaria. The present study explores the language of PILs of seven common ailments in Ghana. In all, 68 leaflets were purposely sampled for the study. Using SMOG and Flesch Kincaid grade level readability formulae, the researcher measured the readability of PILs and discovered that the readability of all the PILs was difficult to read except the dewormer leaflets that scored standard reading score. Further statistical analysis reveal that the lexical and syntactic complexity of the leaflets were not statistically different. Finally, an interview with 20 patients confirmed that the leaflets are difficult to read due to the complex words and long sentence structures. It is recommended that the PILs be revised to make the leaflets readable. 展开更多

Charles Dickens is one of the greatest critical realist writers of the Victorian Age.In language,he is often compared with William Shakespeare for his adeptness with the vernacular and large vocabulary.Charles Dickens achieved a recognizable place among English writers through the use of the stylistic features in his fictional language.Oliver Twist is the best representative of Charles Dickens’style,which makes it the most appropriate choice for the present stylistic study on Charles Dickens.No one who has ever read the dehumanizing workhouse scenes of Oliver Twist and the dark,criminal underworld life can forget them.This thesis attempts to investigate Oliver Twist through the approach of modern stylistics,particularly the theory of linguistic devia tion.This thesis consists of an introduction,the main body and a conclusion.The introduction offers a brief summary of the com ments on Charles Dickens and Chapter X of Oliver Twist,introduces the newly rising linguistic deviation theories,and brings about the theories on which this thesis settles.The main body explores the deviation effects produced from four aspects:lexical deviation,grammatical deviation,graphological deviation,and semantic deviation.It endeavors to show Dickens’manipulating language and the effects achieved through this manipulation.The conclusion mainly sums up the previous analysis,and reveals the theme of the novel,positive effect of linguistic deviation and significance of deviation application. 展开更多

It has been widely acknowledged that vocabulary is central to language acquisition; however, vocabulary teaching in college classrooms does not seem quite fruitful. Students' oral and wriuten discourse reveals surprisingly high rate of deviant usages. A scientific and effective way of teaching and learning vocabulary is therefore strongly desired. This essay explores a comparatively new approach — 'chunking', which is considered as the key to an understanding of how language works. Theoretical underpinnings of this approach suitable for college classrooms are examined before suggestions and pedagogical implications are made as to how to raise students' chunking awareness. 展开更多
