Funtion for Headline reference with article

@riseandshine0 But the headline is subject to the article. So if you'd run it through a static dictionary, it would not be personalized to the article. I think you could better cross-reference words and synonyms in the title with words in the article.

This would just as easy as the dictionary idea.

首先阅读 issue #10 中引用的讨论，并找到分析文章链接的 classifier 入口点。在决定单词与同义词之间的交叉引用应如何工作之前，先确定标题和文章正文目前是如何表示的。当有一份达成共识的实现和测试，能够表明标题相关性是根据文章而不是静态词典进行评估时，即视为完成。
