Contrastive Study of Thinking Modes between Chinese and English and Thinking Training of English Writing for Chinese Students

Based on the relationship between language and thinking, this paper is designed to inform that Chinese mode of thinking has great effect on college students＇ English writing from the perspective of contrastive study of thinking modes between Chinese and English. In addition, one specific measure about training English mode of thinking is put forward.

Exploiting PLSA model and conditional random field for refining image annotation

This paper presents a new method for refining image annotation by integrating probabilistic la- tent semantic analysis （PLSA） with conditional random field （CRF）. First a PLSA model with asymmetric modalities is constructed to predict a candidate set of annotations with confidence scores, and then model semantic relationship among the candidate annotations by leveraging conditional ran- dom field. In CRF, the confidence scores generated lay the PLSA model and the Fliekr distance be- tween pairwise candidate annotations are considered as local evidences and contextual potentials re- spectively. The novelty of our method mainly lies in two aspects ： exploiting PLSA to predict a candi- date set of annotations with confidence scores as well as CRF to further explore the semantic context among candidate annotations for precise image annotation. To demonstrate the effectiveness of the method proposed in this paper, an experiment is conducted on the standard Corel dataset and its re- sults are ＇compared favorably with several state-of-the-art approaches.

Using SVM to construct a Chinese dependency parser

In Chinese, dependency analysis has been shown to be a powerful syntactic parser because the order of phrases in a sentence is relatively free compared with English. Conventional dependency parsers require a number of sophisticated rules that have to be handcrafted by linguists, and are too cumbersome to maintain. To solve the problem, a parser using SVM (Support Vector Machine) is introduced. First, a new strategy of dependency analysis is proposed. Then some chosen feature types are used for learning and for creating the modification matrix using SVM. Finally, the dependency of phrases in the sentence is generated. Experiments conducted to analyze how each type of feature affects parsing accuracy, showed that the model can increase accuracy of the dependency parser by 9.2%.

Constraint-induced aphasia therapy for patients with aphasia: A systematic review

Objectives:This study aimed to systematically evaluate the effects of constraint-induced aphasia therapy(OAT)for aphasic patients reported by randomized controlled trials.Methods:Relevant randomized controlled trials were retrieved from 11 electronic databases.A methodological quality assessment was conducted in accordance with the Cochrane Handbook,and metaanalyses were performed by using RevMan 5.2.A descriptive analysis was conducted when the included trials were not suitable for a meta-analysis.Results:A total of 12 trials were included.A statistically significant group difference was shown from the meta-analysis in the results measured by the Western Aphasia Battery(random-effects model,MD=1.23,95%CI=0.31 to 2.14,P<0.01).However,there were no statistically significant differences shown in the results of the Boston Naming Test(fixed-effects model,MD=-1.79,95%CI=-11.19 to Z62,P>0.05)and Aachen Aphasia Test(fixed-effects model,MD=-1.11,95%CI=-4.49 to 2.27,P>0.05).The descriptive analysis showed positive results in language performances of naming,repetition,and comprehension.Conclusion:This systematic review indicated that CIAT was efficient for improving language performance with regard to naming,comprehension,repetition,written language,and oral language based on the current evidence.And this review provides some meaningful guides for clinical practice:expand the therapy duration to 2 or 3 h per day,focus on naming,and choose the best assessment tool.It also indicates a need for more rigorous,large-scale,and high-quality trials in the future.

Teaching Maritime English： A Linguistic Approach

The purpose of the paper is to outline the parameters of a LCC （linguistically centered concept） of developing ME （maritime English） teaching materials for non-native learners who are beginning their maritime academic career. The paper introduces initial notions on applying linguistic criteria as the basic ones in the process of creating ME textbooks. Through the historical development and under the influence of extra linguistic factors （globalization of the shipping industry, in particular）, ME has accumulated and stored various resources being in current use： vocabulary, grammar and phonology, operational and semiotic systems, specific means of communication, functional models, patterns of narration and description, etc.. The proper linguistic analysis makes a secure foundation for methodology which can guarantee a better quality of ME course books for the 1st and 2nd year maritime students all over the world.

The Critical Discourse Analysis of a report on Barack Obama

Critical Discourse Analysis （CDA） is a new method in linguistic analysis. Usually approached from the angles of linguistics, sociology and psychology, CDA aims to uncover through analyzing linguistic forms, the relations between language and ideology. By applying the specific methods of transitivity, transformation, modality and classification in CDA to a report on Barack Obama in The New York Times--a mainstream media in the United States, this paper aims to reveal the ideology hidden in the report, so as to raise the readers＇ awareness of perceiving unconscious ideologies in news and help them to have a deeper understanding of news and the language in news.

Contrastive Analysis of the Middle Construction

The English Middle Construction (EMC), as a piculiar syntactic structure, shares its semantic features, but diversifies in its syntactic configuration compared with other languages. This paper tries to have a contrast study of the Middle Construcitons between English and Chinese and find the two languages share the same semantic features that the incompatibility between the semantic quantitatives (SQs) of the Adverb (Adjunct in the syntactic term) and the SQs of the Verb denoted by the predicate of MC leads to the deactivization of the predicate by means of the Adjunct, functioning as a quantitative device, assign delimitation to the predicate, hence ensures the grammaticality of the construction. But syntatically, we agree that the NP Movement Approach accounts for the formation of EMC, while we argue in Chinese it is the verb raising that results in the MC. This paper first represents the structural representation of the English Middle Construction; then the structural analysis is elaborated in comparison with that in Chinese, based on the previous studies; and finally the motivations of the Ecs in the perspective of syntactic and semantic functions are explored and hence a new hypothesis is raised to probe the similar construction in Chinese.

Chinese spoken language understanding in SHTQS

Spoken dialogue systems are an active research field with wide applications. But the differences in the Chinese spoken dialogue system are not as distinct as that of English. In Chinese spoken dialogues, there are many language phenomena. Firstly, most utterances are ill-formed. Secondly, ellipsis, anaphora and negation are also widely used in Chinese spoken dialogue. Determining how to extract semantic information from incomplete sentences and resolve negation, anaphora and ellipsis is crucial. SHTQS (Shanghai Transportation Query System) is an intelligent telephone-based spoken dialogue system providing information about the best route between any two sites in Shanghai. After a brief description of the system, the natural language processing is emphasized. Speech recognition sentences unavoidably contain errors. In language sequence processing procedures, these errors can be easily passed to the later parts and take on a ripple effect. To detect and recover these from errors as early as possible, language-processing strategies are specially considered. For errors resulting from divided words in speech recognition, segmentation and POS Tagging approaches that can rectify these errors are designed. Since most of the inquiry utterances are ill-formed and negation, anaphora and ellipsis are common language phenomena, the language understanding must be adequately adaptive. So, a partial syntactic parsing scheme is adopted and a chart algorithm is used. The parser is based on unification grammar. The semantic frame that extracts from the best arc set of the chart is used to represent the meaning of sentences. The negation, anaphora and ellipsis are also analyzed and corresponding processing approaches are presented. The accuracy of the language processing part is 88.39% and the testing result shows that the language processing strategies are rational and effective.

A case study： Errors and error analysis

Before cognitive approach came into being in the 1960s, errors in L2 learning were always regarded as signs of failure which needed immediate attention from the teacher. By analyzing a student＇s writing, this paper tries to elaborate on the roles that errors can play in L2 learning process.

Presupposition Analysis in Advertising Language

In modem society, advertising plays a very important role in people＇s daily life. We can not imagine the world without advertisements. Advertisers try every means to design persuasive advertisements for their products by attractive patterns, photos and colors, as well as commonly shared resources of language. The use of presupposition in advertising language, which is an important topic in pragmaties, can serve the function fairly well. This paper first presents a general review of previous studies on presupposition phenomena in advertising language, then investigates the use of presuppositions in advertising language by both qualitative and quantitative analyses. By qualitative analysis, the author tries to explore the functions of each type of presuppositions in advertising texts; by quantitative analysis, 100 sentences selected from various advertisements for different products are examined.

Comparative Analysis of Modal Auxiliary Verbs in English and in Chinese

The study of modal auxiliary verbs has been done by comparing modal auxiliary verbs in English with the ones in Chinese qualitatively and quantitatively. The modals in English and in Chinese are statistically analyzed through their forms and meanings. The data consists of 50 pieces of Chinese prose with their 50 English translation versions called corpus A and 50 pieces of English prose with their Chinese translation versions called corpus B, altogether 200 articles, which represent a type of discourse that is rich in modal auxiliary verbs both in English and in Chinese The major findings are as follows： （1） The three criteria： inversion, negation, and the use of pro-forms can be used to define both English and Chinese auxiliaries; （2） the modals of both languages can be analyzed within the same semantic categories： volition, probability, and necessity; （3） Chinese epistemic modals can have inversion patterns; （4） the negative forms of Chinese modals are more complex than those of English modals; and （5） the statistic analysis shows that the modals in probability category both in English and in Chinese are used much more often compared to the other two categories： volition and necessity and that deontic modals are used much fewer in both languages to express necessity

Literature and the Teaching of Stylistics： An Investigation Into the Pragmatics of Community Formation in the Educational Context of Namibia

The author＇s paper is an attempt to investigate the success of the pedagogy of stylistics and pedagogical stylistics in the Namibian context. As an applied linguistics course, stylistics is eminently suitable for study and analysis of literature, because it clearly explicates literary effects through linguistic analysis. Many scholars have illustrated the use of stylistics analysis for the purposes of studying literature and teaching it, which is, pedagogical stylistics. However, this paper combines both the study of Stylistics as a discipline, which is the pedagogy of Stylistics, and the use of stylistics for teaching literature in general and poetry in particular. Namibia adopted English as its official language 22 years ago. Since then, both teachers and students have been struggling with the analysis of poetry. This study is an empirical one using qualitative methods in the author＇s research to determine the impact of the study of Stylistics on the understanding and teaching of literature in Namibia. The author uses traditional British poetry from the 16th century up to the 20th century alongside postcolonial poetry to assess the importance of culture in understanding poetry and examine the advantage of using stylistics to teach the poems that the author selects.

Video Concept Detection Based on Multiple Features and Classifiers Fusion

The rapid growth of multimedia content necessitates powerful technologies to filter, classify, index and retrieve video documents more efficiently. However, the essential bottleneck of image and video analysis is the problem of semantic gap that low level features extracted by computers always fail to coincide with high-level concepts interpreted by humans. In this paper, we present a generic scheme for the detection video semantic concepts based on multiple visual features machine learning. Various global and local low-level visual features are systelrtically investigated, and kernelbased learning method equips the concept detection system to explore the potential of these features. Then we combine the different features and sub-systen on both classifier-level and kernel-level fusion that contribute to a more robust system Our proposed system is tested on the TRECVID dataset. The resulted Mean Average Precision （MAP） score is rmch better than the benchmark perforrmnce, which proves that our concepts detection engine develops a generic model and perforrrs well on both object and scene type concepts.

What Motivate Sudanese Students to Leam English as a Foreign Language？

While there are several research studies that planned to discover what drives students＇ motivation to learn English as a foreign/second language, to our knowledge there have been no pragmatic studies in the field of EFL that examined Sudanese college-level students learning motivation. This study, therefore, intends to investigate Sudanese college-level students＇ motivation and its correlation to student＇s achievement. With strong emphasis on motivation, this study is, also examining the relationship between students＇ motivation and achievement when learning English as foreign language. The participants in this study were college-level students in Sudan. The data was collected from 60 college level students. This quantitative study employed both Pearson Correlation methods of analysis as well as ANOVA Regression analysis. The results of this study revealed that there is strong correlation between students＇ motivation and students＇ achievement.
