由于机器可读的文件已经变得普遍，一些最近的研究提出了使用的引用链接和它的上下文相结合的检索方法。在共引链接的情况下，已经尝试通过检查文献中引文的位置来辨别“强”共引与“弱"共引。然而，这个有前途的概念尚未得到充分的评估，目前还不清楚是否搜索性能显着提高。因此，本文通过比较六种检索方法的检索性能，探讨了是否使用共引上下文和使用被引频率归一化的影响，更深入、更广泛地探讨了使用共引上下文的效果。为了实证评估效果，一个特殊的测试集合，从CiteSeer元数据创建，并通过两个IR度量（AP和nDCG）的搜索性能的六种检索方法进行了比较。本文的主要结论是：（1）共引语境对共引检索有积极的影响;（2）使用被引频次的归一化技术对基于语境的共引检索有一定的帮助;（3）共引语境的使用方式对检索性能有一定的影响。
Since machine-readable documents have become widespread, some recent studies have proposed retrieval methods using a combination of citation linkage and its context. In the case of co-citation linkage, there have been attempts to discern ‘strong’ co-citations from ‘weak’ ones by examining the positions of citations in a document. However, this promising concept has not yet been sufficiently evaluated, and it remains unclear whether search performance is significantly improved. Therefore, this paper explores the effects of using co-citation context more deeply and more widely by comparing the search performance of six retrieval methods, which differ as to whether co-citation context and normalization using cited frequency are used. For empirically evaluating the effects, a special test collection was created from CiteSeer Metadata, and the search performances of the six retrieval methods were compared by two IR metrics (AP and nDCG). The main conclusions of this paper are: (1) co-citation context has a positive effect on co-citation searching; (2) the normalization technique using cited frequency is useful for context-based co-citation searching; (3) approaches of using co-citation context tend to affect the characteristics of search performance.
