相关性判据与目标信息类型的关系分析

The Relationship Between Relevance Criteria and Target Information Type

[目的/意义]相关性具有多维性,任何一个维度的改变都会对相关性判据产生相应的影响,目标信息类型是相关性概念诸多维度之一,然而二者之间缺乏足够数据的研究和相应的判断与解释。[方法/过程]通过对1990年以来文献的纵向分析和比较,描述了目标信息类型对相关性判断研究焦点以及研究成果存在影响的现象,提出了相关性判据研究受到目标信息类型变迁驱动,相关性判据集合呈现以文本相关性判据为主体、以目标信息相关的特异性判据为补充的整体结构。[结果/结论]研究提出了下一步相关性判据研究宜充分考虑数据已经成为主流目标信息类型的情况,同时应更重视相关性判据集合存在的跨目标信息类型的共性判据与目标信息类型相关的特异性判据两个子集合的情况。

[Purpose/Significance]Relevance is multidimensional. The change of any dimension will have a corresponding impact on the relevance criteria. Target imformation type is one of the dimensions of the relevance. However the study on the relationship between them lacks of enough data and the corresponding interpretation.[Method/Process]Through the longitudinal analysis and comparison of the related papers since 1990,we describe the influence of target information types on relevance judgment research focus and results. Then we put forward that relevance criteria reseach is driven by target information type,the overall structure of the relevance criteria set is characterized by literature relevance criteria as the main component,and the specific criteria related to target information as supplementary.[Result/Conclusion]The further research should give full consideration to the situation that data has become a main target information type,and should pay more attention to the common criteria across different target information types and the specific criteria which are related with the target information types.
