中文摘要： 本项目拟引入两个新的概念TSD（术语空间密度）和TDC（术语区别能力），来探测学术资源数据集合中术语及其他学术对象空间的总体特征状况和个体分布规律，分析优质对象及其形成原因，以提供有效的知识服务。研究重点：对TSD和TDC的概念进行系统定义，据此实现其测度算法并进行有效性检验；全面探测不同来源术语TDC的显著差别，分析差别存在的原因，从而对不同来源术语作为索引词的质量进行评价，并提出改善索引系统有效性的建设性意见；深入分析学术对象术语发散或聚集的原因，探讨“好”术语与内容质量、学科创新之间的内在联系，进而为学术对象研究内容的合理调整提出可行性建议；总结学科内学术对象空间分布的特征和规律，探讨优质对象与其研究内容、发展方向以及对学科的贡献等之间的关系，从而促进学术对象的健康发展。最终目标：撰写研究报告《面向学术资源的TSD与TDC测度及分析研究》；实现TSD与TDC的测算和可视化展示平台。

英文摘要： The project prepares to introduce two new concepts named as TSD(Term Space Density) and TDS(Term Discriminative Capacity), to detect the overall characteristics status and individual distribution laws of term space and spaces of other academic objects in data collection of academic resources, to analyze the high-quality objects and the causes they formed, so that to provide effective knowledge services. The research of this project will focus on the following aspects: systematically defining the intension and extension of TSD and TDC, according to which realizing their measure algorithms and conducting validation; comprehensively detecting the significant differences of TDC-values of terms from distinct sources, and analyzing the reasons why the difference are existing, so that to evaluate the quality of indexing terms from distinct fields and with different subject characteristics, and then making constructive suggestion to improve the effectiveness of the index system; analyzing in-depth the reasons why terms belonging to academic objects spread out or clustered together in the space, and exploring the internal relationship between “good” terms and the quality of subject content and discipline innovation, so that to put forward feasibility proposals for reasonable adjustments to domain areas of academic objects studying; summarizing the characteristics and laws of spatial distribution of academic objects within a discipline, and investigating the relationship between high-quality objects and their research fields, development directions and contributions to the discipline and so on, so that to promote the healthy development of academic objects. Finishing the research report named as “Studies on measurement and analysis of Term Space Density and Term Discriminative capacity oriented academic resources” and achieving a platform for calculation and visual display of TSD and TDC will be considered as final objectives of this project.
