In order to resolve the embedding problem, context information of a graph production in the CAGG is represented in the form of context attributes of the nodes involved. Moreover, several properties of a set of confluent CAGG productions are characterized, and then an algorithm based on them is developed to decide whether or not a set of productions is confluent, which provides the foundation for the design of efficient parsing algorithms. It can also be shown through the comparison of CAGG with several typical context-sensitive graph grammars that CAGG is more succinct and, at the same time, more intuitive than the others, making it more suitably and effortlessly applicable to the specification of visual languages.展开更多

We utilize the fuzzy linguistic scale to construct a linguistic preference matrix, and propose a fuzzy induced ordered weighted geometric averaging (FIOWGA) operator to aggregate linguistic preference information. A method based on the fuzzy linguistic scale and FIOWGA operator for decision-making problems is presented. Finally, an illustrative example is given to verify the developed method and to demonstrate its feasibility and effectiveness.展开更多

The study is based on analysis of personal counseling experience, where literature was used as a tool to disclose client's personal meanings. During our sessions, clients were observed phenomenologically, and their speach was written down. Reflecting on the qualitative data of transformative learning in language arts, we developed techniques for facilitation and disclosure of personal meanings. Grounded theory was used for data generalization: Personal educational insights and its comparison with other researchers' theoretical insights were the basis to develop the methodical system for psychological guidance and counseling and to explain it. We revealed that focus on personally important meanings during discussion after literature reading has influence on the mental state of personality and deepens the interactions with the literature art, so we suggest a spiral model to explain the methodical system of our method. Transformative learning in language arts as a method of guidance and counseling can be understood as spiritual motion by spirale. It has three levels: (1) art level (interaction with the literature); (2) psychology level (counseling); and (3) art level (interaction with the same peace of literature as in the beginning of the session, poetic summary of the session). Levels (1) and (3) mean interaction with literature art, but at the third level, this interaction has new quality, because personality has better perception of Self and more ability to connect personal meanings and literature wisdom. At the first level, we have direction from literature to Personality. At the third level, we have direction from the Self (Speaking from Within) to literature. Disclosure of personally important meanings is a key to self-understanding and poetical thinking; our developed methodical system reduces emotional tension and strengthens interconnectedness between inner and outer world and improves poetical understanding. In this paper, the methodical system of transformative learning and guidance is discussed.展开更多

But the standard SVM cannot deal with length-variable vectors, which is one severe obstacle for its applications to some important areas, such as speech recognition and part-of-speech tagging. The paper proposed a novel SVM with discriminative dynamic time alignment ( DDTA - SVM) to solve this problem. When training DDTA - SVM classifier, according to the category information of the training sampies, different time alignment strategies were adopted to manipulate them in the kernel functions, which contributed to great improvement for training speed and generalization capability of the classifier. Since the alignment operator was embedded in kernel functions, the training algorithms of standard SVM were still compatible in DDTA- SVM. In order to increase the reliability of the classification, a new classification algorithm was suggested. The preliminary experimental results on Chinese confusable syllables speech classification task show that DDTA- SVM obtains faster convergence speed and better classification performance than dynamic time alignment kernel SVM ( DTAK - SVM). Moreover, DDTA - SVM also gives higher classification precision compared to the conventional HMM. This proves that the proposed method is effective, especially for confusable length - variable pattern classification tasks展开更多

In contrast to English, Chinese does not have perfect constructions. English perfective aspect is an actual aspect indication: duration and completion of an action or situation. According to different reference time, the actual aspect can be divided into past actuality, present actuality and future actuality. This paper will undoubtedly contribute to the study of tense-aspect in Chinese. The study of English perfective aspect is conducive to the comparative study and translation of aspect in English and Chinese.展开更多

The subjects were selected from Malaysian university students majoring in English at University Sains Malaysia. Data were collected through an open-ended questionnaire in the form of a discourse completion task and a semi-structured interview. The responses were analyzed based on Rinnert and Nogami's (2006) taxonomy of the speech act of complaint to examine the main components of complaint, the level of directness and the degree of mitigation. It is anticipated that the findings will be able to provide valuable insights into teaching and learning English in non-native settings.展开更多

Idols and B-boys stages are fun, touching, and fantastic. Today, South Korean students are excited and enthusiastic about their colorful dance moves. The study is about creative educational methods that use K-pop music videos to learn the proverbs and old words that our ancestors learned to keep in mind and teach. K-pop lyrics are a rich reflection of the experiences of life and the world in which people are living today. Accordingly, this study can present new teaching and learning method examples that are used in class related to the old language associated with K-pop lyrics and can also introduce interesting class materials.展开更多

But does everybody born by an Urhobo parent speak Urhobo? From our observation, the answer to this question is clearly "no". Many of the Urhobo people in the Diaspora as well as those at home have chosen to shift from their own language to other languages. Hence Urhobo language has gradually acquired the status of a second language. Therefore, its teaching would also veer away from language teaching methods that are used for first languages. Based on Noam Chomsky's theory of Generative Grammar, aspects of the Urhobo grammar will be treated as we present specifically the verb "edia"/"to be". As it is, it is being presented as a second language bearing in mind the great population of Urhobo people in the Diaspora as well as Mowarin's "miguo generation" of Urhobo children back home in Urhobo land. This being so, the methods applied in this study are the Grammar Translation Method Approach as well as the Direct Method Approach. To facilitate its learning especially for the new generation of Urhobo persons, the poetic approach would also be applied.展开更多
