本文提出了一种通过从研究论文标题中提取符合我们信息需求和兴趣的词n图来探索技术短语框架的方法。技术短语框架是我们方法的结果，是带有通配符的短语，可以替换任何技术术语。我们的方法首先从研究论文的标题中提取词的三元组，并构建三元组的共现图。即使简单地将Page Rank算法应用于共现图，我们也可以得到在Page Rank得分较高的级别上可以视为技术关键短语的三元组。相比之下，我们的方法是基于三元组之间的Jaccard相似性为共现图的边缘分配权重，然后应用加权的Page Rank算法。因此，我们得到了截然不同但更有趣的结果。通过未加权的Page Rank获得的排名靠前的三元组只有一个自包含的含义，而通过我们的方法获得的是技术短语框架，即只有在其之前或之后放置一个（或多个）技术单词后才能形成完整技术短语的单词序列。我们声称我们的方法是发现重要短语逻辑模式的有用工具，可以扩展查询关键字以提高信息检索性能，也可以作为技术写作中的候选短语，使我们的研究论文更具吸引力。
This paper proposes a method for exploring technical phrase frames by extracting word n-grams that match our information needs and interests from research paper titles. Technical phrase frames, the outcome of our method, are phrases with wildcards that may be substituted for any technical term. Our method, first of all, extracts word trigrams from research paper titles and constructs a co-occurrence graph of the trigrams. Even by simply applying Page Rank algorithm to the co-occurrence graph, we obtain the trigrams that can be regarded as technical key phrases at the higher ranks in terms of Page Rank score. In contrast, our method assigns weights to the edges of the co-occurrence graph based on Jaccard similarity between trigrams and then apply weighted Page Rank algorithm. Consequently, we obtain widely different but more interesting results. While the top-ranked trigrams obtained by unweighted Page Rank have just a self-contained meaning, those obtained by our method are technical phrase frames, i.e., A word sequence that forms a complete technical phrase only after putting a technical word (or words) before or/and after it. We claim that our method is a useful tool for discovering important phrase logical patterns, which can expand query keywords for improving information retrieval performance and can also work as candidate phrasings in technical writing to make our research papers attractive.
