全国中文机读书目主题标引格式问题分析   总被引：9，自引：0，他引：9  

朱芊 《中国图书馆学报》2002,28(1)

中文机读书目主题标引格式的不统一 ,会产生书目主题格式多样的弊端。其主要原因是由于叙词法后组式标题只能套录标题法先组式标题格式。因此 ,必须统一中文书目主题标引格式。表 2。参考文献 8。  相似文献

Validating Automated Measures of Text Complexity          下载免费PDF全文

Kathleen M. Sheehan 《Educational Measurement》2017,36(4):35-43

Automated text complexity measurement tools (also called readability metrics) have been proposed as a way to help teachers, textbook publishers, and assessment developers select texts that are closely aligned with the new, more demanding text complexity expectations specified in the Common Core State Standards. This article examines a critical element of the validity arguments presented in support of proposed metrics: the claim that criterion text complexity scores developed from students’ responses to reading comprehension test items are reflective of the difficulties actually experienced by students while reading. Evidence that fails to support this assertion is examined, and implications relative to the goal of obtaining valid, unbiased evidence about the measurement properties of proposed readability metrics are discussed.  相似文献

Generalized Hamming Distance   总被引：4，自引：0，他引：4  

Abraham Bookstein  Vladimir A. Kulyukin  Timo Raita 《Information Retrieval》2002,5(4):353-375

Many problems in information retrieval and related fields depend on a reliable measure of the distance or similarity between objects that, most frequently, are represented as vectors. This paper considers vectors of bits. Such data structures implement entities as diverse as bitmaps that indicate the occurrences of terms and bitstrings indicating the presence of edges in images. For such applications, a popular distance measure is the Hamming distance. The value of the Hamming distance for information retrieval applications is limited by the fact that it counts only exact matches, whereas in information retrieval, corresponding bits that are close by can still be considered to be almost identical. We define a Generalized Hamming distance that extends the Hamming concept to give partial credit for near misses, and suggest a dynamic programming algorithm that permits it to be computed efficiently. We envision many uses for such a measure. In this paper we define and prove some basic properties of the Generalized Hamming distance, and illustrate its use in the area of object recognition. We evaluate our implementation in a series of experiments, using autonomous robots to test the measure's effectiveness in relating similar bitstrings.  相似文献

An evaluation framework for cross-lingual link discovery     

Ling-Xiang Tang  Shlomo Geva  Andrew Trotman  Yue Xu  Kelly Y. Itakura 《Information processing & management》2014

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9.  相似文献
