Narrative Voices and Theme in The House of the Seven Gables

Under the instruction of the author's own confession in the preface of The House of the Seven Gables, it's easy for readers and critics to take the theme of this novel as past and present, stasis and change, aristocracy and democracy, and then to unfavor?ably judge Pycheon siblings, the representatives of the former, by Holgrave, that of the latter. However, by using two narrative voic?es simultaneously in the novel, an intradiegeitic one and an extradeigetic one, Hawthorne actually reveals his equal disapproval of both the Pycheon siblings and Holgrave. In the intradiegetic narrative, the narrative voice as a whole takes its side with Holgrave and reveals Pycheon siblings'isolation from the united struggle of mankind. In the extradiegetic narrative where the narrator ad?dresses directly to his readers, the narrator expresses a similar disapproval of Holgrave, who is equally isolated from the chain of hu?manity for lacking sympathy for his fellow beings. With the co-existence of two narrative voices, Hawthorne's true concern lies in calling attention to the equally dangerous situations of isolation from the chain of humanity:an isolation from the chain of progress and that of human sympathy.     

新课程改革下语文学科的农村化探索——乡村孩子的趣味语文

语文课堂在新课改之后出现了一个崭新的局面:教师的教学理念更新了,教学方式方法改进了,师生之间角色的转换实现了。但是,地处偏远山区的乡村中学,学生因缺乏语文学习的环境而丢失了语文学习的积极性、主动性,从而将包罗万象、富有趣味的语文学科搁浅。因此,在乡村中学的语文课堂教学中应该充分挖掘语文学习的趣味性,还原并升华语文教学应有的精彩内容。

浅论鲁迅杂文的抒情方式

鲁迅是一个以心发现心的人,在其剑拔弩张的杂文背后,隐含着一股情感的激流,熔铸着他浓烈饱满的爱憎之情,然而这种情感的抒发和表达方式却不尽相同:有的较为外露,有的则倾于内向。无论是溢于言表的悲愤激扬,还是沉郁含蓄的抒而不发无不体现出其“情感中的理性的美”。     

Use of place information for improved event tracking

The main purpose of topic detection and tracking (TDT) is to detect, group, and organize newspaper articles reporting on the same event. Since an event is a reported occurrence at a specific time and place and the unavoidable consequences, TDT can benefit from an explicit use of time and place information. In this work, we focused on place information, using time information as in the previous research. News articles were analyzed for their characteristics of place information, and a new topic tracking method was proposed to incorporate the analysis results on place information. Experiments show that appropriate use of place information extracted automatically from news articles indeed helps event tracking that identify news articles reporting on the same events.

Optimization of some factors affecting the performance of query expansion

This paper examines the factors affecting the performance of global query expansion based on term co-occurrence data and suggests a way to maximize the retrieval effectiveness. Major parameters to be optimized through experiments are term similarity measure and the weighting scheme of additional terms. The evaluation of four similarity measures tested in query expansion reveal that mutual information and Yule's Y, which emphasize low frequency terms, achieve better performance than cosine and Jaccard coefficients that have the reverse tendency. In the evaluation of three weighting schemes, similarity weight performs well only with short queries, whereas fixed weights of approximately 0.5 and similarity rank weights were effective with queries of any length. Furthermore, the optimal similarity rank weight achieving the best overall performance seems to be the least affected by test collections and the number of additional terms. For the efficiency of retrieval, the number of additional terms needs not exceed 70 in our test collections, but the optimal number may vary according to the characteristics of the similarity measure employed.
