本文提出了一种利用传播共被引关系进行文献检索的方法。为了明确该方法是否有可能提高共被引检索的检索性能，我们对两种检索方法进行了评估：一种直接使用关系；另一种结合了共引上下文。在一个包含约152,000份文件的特殊测试集上进行了实验。结果表明，该关系能够检测到传统共被引关系无法检测到的相关文献，并且使用上下文对减少噪声文献的数量具有积极作用。
This paper proposes a measure that uses a spread co-citation relationship for document retrieval. To clarify whether this proposed measure has potential for enhancing the search performance of co-citation searching, two retrieval methods are evaluated: one uses the relationship directly; the other incorporates the co-citation context. Experiments with a special test collection comprising about 152,000 documents are conducted. Results indicate that this relationship tends to be able to detect relevant documents which are undetectable using a traditional co-citation relationship, and that using context has a positive effect to reduce the number of noise documents.
