We investigated how to effectively apply link analysis techniques to the tasks of natural language processing. Specifically, we developed a method for analyzing conjunctive structures in natural language sentences. The method borrows an idea from the similarity computation method in link analysis, which counts all paths between the nodes of interest. Our proposed method applied the idea to finding the most similar phrases in a sentence, which are likely to form coordination. We also proposed a graph construction method that reduces the influence of "hubs", which are the nodes located close by to many other nodes in a graph.

我们研究了如何有效地将链接分析技术应用于自然语言处理任务。具体来说，我们开发了一种分析自然语言句子中的连接结构的方法。该方法借鉴了链路分析中相似度计算方法的思想，对感兴趣节点之间的所有路径进行计数。我们提出的方法应用这个想法来寻找句子中最相似的短语，这些短语可能形成协调。我们还提出了一种图构造方法，可以减少“中心”的影响，“中心”是图中靠近许多其他节点的节点。
