Searching strategies for the Bulgarian language

This paper reports on the underlying IR problems encountered when indexing and searching with the Bulgarian language. For this language we propose a general light stemmer and demonstrate that it can be quite effective, producing significantly better MAP (around + 34%) than an approach not applying stemming. We implement the GL2 model derived from the Divergence from Randomness paradigm and find its retrieval effectiveness better than other probabilistic, vector-space and language models. The resulting MAP is found to be about 50% better than the classical tf idf approach. Moreover, increasing the query size enhances the MAP by around 10% (from T to TD). In order to compare the retrieval effectiveness of our suggested stopword list and the light stemmer developed for the Bulgarian language, we conduct a set of experiments on another stopword list and also a more complex and aggressive stemmer. Results tend to indicate that there is no statistically significant difference between these variants and our suggested approach. This paper evaluates other indexing strategies such as 4-gram indexing and indexing based on the automatic decompounding of compound words. Finally, we analyze certain queries to discover why we obtained poor results, when indexing Bulgarian documents using the suggested word-based approach.

研究型大学的文献资源建设探析--对86所大学图书馆的调查

根据《中国大学指南》并参阅相关献,研究86所“211工程”国家重点建设大学的献资源和相关情况后得出结论：当前图书馆的馆藏仍以印刷型献为主,与发达国家相比差距较大。建议研究型大学在献资源建设中制定一些可以达到的目标,做到完善制度,确保经费到位;加强督导,推动资源共享;着眼未来,加速网络建设。     

Are fame and fortune the kiss of death?

Trade and scholarly publishers often urge academic authors to reach out to an audience beyond their peers. One obstacle to expanding the audience for new scholarship is the widespread belief that it requires "pandering to the lowest common denominator," or "dumbing down," and that the scholar turned "popularizer" will be shunned by the academy. Where did this academic myth come from? Is there any truth behind it? What can an editor say to the academic author who fears that publishing success will spell the end of academic respectability?
