摘要
排序技术是信息检索系统进行结果处理的核心技术,排序算法的优劣直接影响系统的效率。将现有的排序算法分为基于链接分析和基于机器学习两大类,系统地分析了各自代表性算法,指出它们各自的优势和存在的不足,并指出不同算法在不同领域和场合所具有的优势,最后讨论可继续研究的课题。
The ranking technology is a core technology of tire result reduction for inforn^tion retrieval system, and the ranking algorithm directly influence its efficacy. The two kinds of ranking algorithms are link analysis-based and machine learning-based. This paper systematically analyzed representative ranking algorithms respectively and pointed out their advantages and deficiency, different ranking algorithms had different performance in different domains, discussed the future issues at last.
