具有焦点标记作用的“是”字句重音分布研究

本研究以汉语中标记焦点的结构“[是[…XP…]]”为研究对象,通过声学和感知实验,系统地考察了这一句式所标记的焦点成分的重音位置及其声学表现。实验结果显示,该句式所标记的焦点位置,以韵律词为单位,音高的音域被整体拉大,后面的成分的音阶被陆续压低,被标记的焦点成分后面通常存在中间短语边界,而在第二个焦点标记前面,通常有语调短语边界。以实验结果为基础,本研究进一步讨论了语法学界争论较多的,关于焦点和重音关系的问题,研究指出,汉语中有标记的焦点位置通常有重音分布,有重音的位置一般伴有语调(音高音域)的变化,但重音和语调的变化不是确定焦点位置的依据。     

AN OPINION FEATURE EXTRACTION APPROACH BASED ON A MULTIDIMENSIONAL SENTENCE ANALYSIS MODEL

With Web 2.0 applications being widely used, social networking services, including web blogs, forums, and other online communities, have become informative tools that help individuals to easily gauge the pulse of the electronic consuming market. As a substitute for traditional public media, the related site provides unique mechanisms to instantly reveal the degree of public product acceptance by either statistically aggregating the rating results or archiving opinions shared by experienced customers. However, the growth of user-generated information and its scattered unstructured contents is overwhelming to users, thereby triggering the demand for a more efficient system that can offer concise information. Most existing efforts dedicated to these issues may neglect vital aspects of the sentence-level context. This article aims to explore the critical features hidden in the sentential structure of opinion articles and expects that the detected patterns may contribute to the enhancement of related applications. Accordingly, a multidimensional sentence modeling algorithm (MSMA) is designed to evaluate various sentential characteristics and adopt a genetic algorithm to optimize the weighting scheme while determining feature importance. The study also makes use of the public knowledge resource Wikipedia as a global reference to fine-tune the feature set's effectiveness and enhance the overall performance of this framework. The results of experiments on an electronic product data set demonstrate that the proposed method is promising and provides significant improvement over previous studies.     

Finding relevant features for Korean comparative sentence extraction

In this paper, we study how to extract comparative sentences from Korean text documents. We decompose our task into three steps: (1) collecting comparative keywords; (2) extracting comparative-sentence candidates by keyword searching; and (3) eliminating non-comparative sentences from these candidates using machine learning techniques. We perform various experiments to find relevant features. As a result, our experiments show significant performance, an F1-score of 90.23%.     

Strategies for processing unbounded dependencies: Lexical information and verb–argument assignment.

This article describes 2 experiments about verb–argument relations in sentence processing in which there is no ambiguity involving the subcategorization of the verb but in which the role that the argument serves is initially unclear. Specifically, a self-paced reading experiment and an eye-tracking experiment investigated the way in which readers form unbounded dependencies when the verb is looking for both a direct object and a clause and when the filler either could be the direct object or could form part of the clause. The results suggested that readers treated the filler as the verb's direct object and probably also considered the clausal analysis at the same time. The results are interpreted with respect to current accounts of parsing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Structural dependency in language production.

The subjects and verbs of English agree in number. This superficially simple operation is regularly implemented by speakers, but occasionally derails in sentences such as "The time for fun and games are over". Such mistakes are interesting because their systematic deviations from the structural dependencies that govern normal agreement may shed light on how such dependencies are ordinarily implemented in speech. There were two issues at the focus of this work. The first had to do with the nature of the information that is used in carrying out agreement, and the second with the scope of processing operations. The findings from several experiments are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

也谈主谓谓语句的范围

以“三个平面”的有关理论为指导,从话题和主语区别的角度来重新审视朱德熙在《语法讲义》中提出的7类主谓谓语句。认为在S1 S2 V的句子中,如果S1表时间或地点,那么该类句子不能看作主谓谓语句。提出了辨别主谓谓语句的7条标准。

Linguistic Attention Control: Attention Shifting Governed by Grammaticized Elements of Language.

In 2 experiments, the authors investigated attention control for tasks involving the processing of grammaticized linguistic stimuli (function words) contextualized in sentence fragments. Attention control was operationalized as shift costs obtained with adult speakers of English in an alternating-runs experimental design (R. D. Rogers & S. Monsell, 1995). Experiment 1 yielded significant attention shift costs between tasks involving judgments about the meanings of grammatical function words. The authors used a 3-stage experimental design (G. Wylie & A. Allport, 2000), and the emerging pattern of results implicated task set reconfiguration and not task set inertia in these shift costs. Experiment 2 further demonstrated that shift costs were lower when the tasks involved shared attentional resources (processing the same grammatical dimension) versus unshared resources (different grammatical dimensions). The authors discuss the results from a cognitive linguistic perspective and for their implications for the view that language itself can serve a special attention-directing function.
