苏轼“以文为四六”与北宋中后期的骈散共存

苏轼在文章改革上,采取的是＂以四六为文＂、＂以文为四六＂的办法,将四六对句运用于散行之文中,在古文创作中融入用典,把＂道＂与四六联系在一起,解决了四六内容的贫乏。在苏轼的影响下,宋代文章已经形成了一个独有的特色,即章奏表启类作品多用四六,其他文章多用散体,实现了骈散共存。     

Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.

Using lexical chains for keyword extraction

Keywords can be considered as condensed versions of documents and short forms of their summaries. In this paper, the problem of automatic extraction of keywords from documents is treated as a supervised learning task. A lexical chain holds a set of semantically related words of a text and it can be said that a lexical chain represents the semantic content of a portion of the text. Although lexical chains have been extensively used in text summarization, their usage for keyword extraction problem has not been fully investigated. In this paper, a keyword extraction technique that uses lexical chains is described, and encouraging results are obtained.     

Authorship attribution based on a probabilistic topic model

This paper describes, evaluates and compares the use of Latent Dirichlet allocation (LDA) as an approach to authorship attribution. Based on this generative probabilistic topic model, we can model each document as a mixture of topic distributions with each topic specifying a distribution over words. Based on author profiles (aggregation of all texts written by the same writer) we suggest computing the distance with a disputed text to determine its possible writer. This distance is based on the difference between the two topic distributions. To evaluate different attribution schemes, we carried out an experiment based on 5408 newspaper articles (Glasgow Herald) written by 20 distinct authors. To complement this experiment, we used 4326 articles extracted from the Italian newspaper La Stampa and written by 20 journalists. This research demonstrates that the LDA-based classification scheme tends to outperform the Delta rule, and the χ² distance, two classical approaches in authorship attribution based on a restricted number of terms. Compared to the Kullback–Leibler divergence, the LDA-based scheme can provide better effectiveness when considering a larger number of terms.     

汉语框架网络知识本体构建研究

汉语框架网络知识本体是以框架语义学为理论基础,有丰富的语料库支撑,揭示了概念的本体关系。其获取,是在构建语料库的基础上,利用叙词表、分类表和其他知识分类体系等现有的知识本体,识别领域内外相关的概念并抽取相应属性,建立概念之间的关系,并利用所识别的概念和关系创建新的本体,融合已有的本体和新建本体。图2。参考文献4。     

Parallelism修辞格探微

Parallelism意为"平行结构",即将结构相同或相似、意义并重、语气-致的语言成分并行排列的一种修辞手法.它与汉语"排比"颇为相似,但不等同.从平行项数来看,它可以有两项,也可以有三项或三项以上,通常以二项或三项并行景为常见;就构成格式而言,它有单层次格式和多层次格式两种.

英语写作中语块使用的实证研究

提高英语写作技能是英语教学的目标之一,但怎样提高写作水平是英语教学亟待解决的难题。将语块理论引入写作教学,为其提供了新的视角。采用SPSS17．0对140名学习者在写作中使用语块的数据分析,发现其特征如下：从语块使用频度上看,语块使用较少,仅占全文的1/3;从语块使用重复率上看,其重复率较高,接近语块总数的1/3,这表明学习者语块使用不够多样化,种类不丰富;从语块类型上看,短语语块使用较多,句子语块使用较少;从学习者水平上看,高分组限制语块使用较多,低分组固定语块使用较多。
