多校区大学管理研究

我国的多校区大学是在当前深化高等教育体制改革的过程中形成的 ,具有不同于国外多校区大学模式的特殊性。我国的多校区大学管理面临着一些基本问题 ,如实质性融合、集权与分权、组织成员对大学组织目标的认同、改善学科布局等。立足于我国高等教育改革实际对这些问题进行研究 ,具有重要的理论意义和现实意义     

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.
