| 摘 要： | 研究发现,非相关文献知识发现有三个理论基础:检索理论、文献计量学理论和逻辑学理论.其中目标性检索策略、共现理论与三段论的逻辑推理是非相关文献知识发现的实际应用理论.目标性检索策略总的原则是缩小范围,提高主题关联度与准确性,这决定了非相关文献知识发现过程中过滤和排序方法的改进方向;而基于三段论逻辑推理的非完全形式化,非相关文献知识发现应改变目前的以完全自动化为目标的研究方向,实现高阶共现框架下的非相关文献知识发现的过滤和排序方法的优化,从而形成人工辅助下的更具实际应用价值的知识发现系统.

| Abstract: | Some studies find that noninteractive literature based discovery has three theoretical principles, including retrieval theory, bibliometrics and logics. Thereinto, targeted retrieval strategy, co occurrence theory, and syllogism are practical theories. The general principle of targeted retrieval strategy is narrowing range and improving relevancy and accuracy, which determines the direction of filtration and sorting method in noninteractive literature based discovery. While based on incomplete formalization of syllogistm, noninteractive literature based discovery should change research direction with a target of full automation and achieve optimization of filtration and sorting method in high level concurrence framework, thus, form a knowledge discovery system with application value under human intervention. 2 figs. 1 tab. 9 refs. |
