有没有好的插件可以生成关键字和摘要，最好为js或者php版本的
有，比较乱，需要自己做实验才知道好坏，摘要本身就是机器学习的范畴，很多人还等拿这东西发论文呢
关键字的话如果建单点可以用命名实体识别/分词词性+高频词库来做
为什么我这里没说词频？词频这东西只是最基本的解决方式，你知道中文有指代的，而且有花式指代，如果一个人名只出现一次，对于娱乐类新闻人名肯定是核心词，但是通篇都用他或者X某指代呢？那他可能在词频算法中就算不出什么来了，因此我建议把命名实体也放进去
摘要就麻烦了，需要提取关键句，而且还要在指定字数内，提取完的句子连起来读还得通顺，我们当时想做没做出来...
当然http://blog.csdn.net/hotallen/article/details/12690499这种文章你也可能搜到
但是里面一句sentence.split()，在中文里就是一个分词组件了
类似参考https://github.com/someus/TextRank4ZH
我还是要说，算法和应用之间的距离不近的，比如这个公司

2013年还在融资，现在服务器已经出错，估计没做下去，老老实实找编辑写摘要吧

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
