This paper makes a typological study on the universality and relativity of the Conceptual Metaphors （CM） of color terms in different languages. It attempts to explore the cognitive differences and similarities in the process of categorization and metaphorization of color terms of oriental and western peoples. It proposes that the CM system of color terms is determined by the interactivity of three factors as neurophysiologic mechanisms, general cognitive psychological mechanisms and socio-cultural selective mechanisms. The CM of color terms in different languages carry their specific cognitive characteristics and cultural values, and reflect self-similarity of the language and culture.展开更多

According to statistical theory, a method which is based on the hidden Markov model is presented to establish ontology mapping. This method considers concepts as models, and attributes, relations, hierarchies, siblings and rules of the concepts as the states of the HMM, respectively. The models corresponding to the concepts are built by virtue of learning many training instances. On the basis of the best state sequence that is decided by the Viterbi algorithm and corresponding to the instance, mapping between the concepts can be established by maximum likelihood estimation. Experimental results show that this method can improve the precision of heterogeneous ontology mapping effectively.展开更多

The tone recognition performance is improved using HCRFs by taking advantage of intra-syllable dynamic, inter-syllable dynamic and duration features. When the tone model is integrated into continuous speech recognition, the discriminative model weight training （DMWT） is proposed. Acoustic and tone scores are scaled by model weights discriminatively trained by the minimum phone error （MPE） criterion. Two schemes of weight training are evaluated and a smoothing technique is used to make training robust to overtraining problem. Experiments show that the accuracies of tone recognition and large vocabulary continuous speech recognition （LVCSR） can be improved by the HCRFs based tone model. Compared with the global weight scheme, continuous speech recognition can be improved by the discriminative trained weight combinations.展开更多

Translating is to reconstruct the original text, which leads to information changes. This change is attributed to translator＇s idiolect and thinking pattern as well as different languages. The translator＇s role is obvious in the text translation. How to be invisible？ Even if invisibility is possible, the invisibility is like a moon in water, flower in fog. That is vague but invisible.展开更多

Conceptual metaphors belong to traditional vocabulary metaphors, and ideational grammatical metaphors are pointed out by Halliday--the main representative of systemic-functional theory. This paper elaborates on the specific grammatical feature of EST （English for Science and Technology） text--＂nominalization of processes＂ to reveal the source of ideational metaphors. From the analysis of some examples, it is found that nominalization as a grammatical metaphor expresses the transference between process types, so it reveals the essence of ideational grammatical metaphors. Meanwhile, the comparison made between grammatical metaphors and vocabulary metaphors reflects the similarities between conceptual metaphors and ideational metaphors. In this way, this paper comes to the conclusion that the combination of the study methods of metaphors from both cognitive and systemic-functional perspectives is the best way to uncover the basic characteristic of human thinking.展开更多

In this paper, Latent Semantic Analysis （LSA） is first used to extract semantic knowledge from a given document, all question paragraphs are identified, an automatic text segmentation approach analogous to Text＇filing is exploited to improve the precision of correlating question paragraphs and answer paragraphs, and finally some ＂important＂ sentences are extracted from the generic content and the question-answer pairs to generate a complete summary. Experimental results showed that our approach is highly efficient and improves significantly the coherence of the summary while not compromising informativeness.展开更多

A large hidden Markov model is applied to model the immittance spectral frequency （ISF） parameters in AMR-WB codec to optimally estimate the lost ISFs based on the minimum mean square error （MMSE） rule. The estimated ISFs are weighted with the ones of their previous neighbors to smooth the speech, resulting in the actual concealed ISF vectors. They are used instead of the lost ISFs in the speech synthesis on the receiver. Comparison is made between the speech concealed by this algorithm and by Annex I of G. 722. 2 specification, and simulation shows that the proposed concealment algorithm can lead to better performance in terms of frequency-weighted spectral distortion and signal-to-noise ratio compared to the baseline method, with an increase of 2.41 dB in signal-to-noise ratio （SNR） and a reduction of 0. 885 dB in frequency-weighted spectral distortion.展开更多

To solve the large embedding capacity problem for real-time information hiding, a steganographic system combined with a watermarking scheme is proposed, which skillfully transfers the secret speech into watermarking information. The basic idea is to use the speech recognition to significantly reduce the size of information that has to be transmitted in a hidden way. Furthermore, an improved DFT watermarking scheme is proposed which adaptively chooses the embedding locations and applies the multi-ary modulation technique. Based on the GUI (Graphical User Interface) software, the CST operates on both ordinary and secure mode. It is a completely digital system with high speech quality. Objective and subjective tests show that the CST is robust against normal signal processing attacks and steganalysis. The proposed scheme can be used in terms of military applications.展开更多

Particularly, interesting is the fact that the language of science is characterized by the use of figurative language, which appeals to the common knowledge of the world, mainly to explain, clarify, and describe intricate concepts. Metaphors are helpful for lexicalizing new concepts and meanings or extending the meanings of pre-existing words. The analysis of tropes as a means to improve foreign language learners＇ reading competence is a rather novel teaching practice in ESP （English for Specific Purposes）, implemented at the University of Rio Cuarto, Argentina. Therefore, the aim of this paper is to explain the theoretical basis for teaching and developing metaphorical competence in ESP classes as a means of providing an intellectually stimulating alternative approach, and to present some teaching ideas and activities designed to familiarize students with the use of metaphorical language in scientific discourse in order to enhance their reading competence.展开更多
