A Corpus-Based Learning Method of Compound Noun Indexing Rules for Korean

In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness.

A Model of Translations

This paper attempts to model translations from one language intoanother. Book markets are an integral part of the cultural life of anation, and new ideas on political, social and cultural aspects arespread by means of books. It is a fact, however, that linguisticbarriers will often prevent a book from reaching a mass audience unlessit is translated. But the mechanism involved in translations has notbeen adequately described. A model is presented here in three steps: Thefirst step is to determine the number of new books in an economy. Thenext step is to determine the propensity to import translated works fromother countries. The final step is to determine from which language thetranslation will originate. This provides a basis for judging thecultural affinity between nations.     

网络环境信息标引的测评与比较研究

网络环境下,文献信息具有数量多、增长快、新词层出不穷等特点。标引是对信息资源进行组织的有效手段和重要环节,标引的质量和效率直接影响信息组织的质量和速度。对受控标引、自由标引和自动标引三种标引方式进行了相符度、专指度、标引深度及通用词数的测试对比.得出自由标引优于受控标引,自动标引优于自由标引及受控标引的结论。     

基于混合索引的中文全文检索系统研究

在中文全文检索系统中引入了混合索引,建立了混合索引之Hash索引,给出了Hash索引在内存中的存储结构,并给出了这种索引下的检索算法。这种索引既能保证索引的全面性,又能提高系统检索效率。通过实际构建系统,探讨了基于混合索引的中文全文检索系统的实现。
