I'm trying to extract triplet subject, predicate, and object from sentence. I need more references on how to do this.

推荐答案

做到这一点的最基本方法是进行浅层解析，然后提取NOUN-VERB-NOUN三元组，并且结果可以接受.这应该适用于所有SVO(主语-动词-宾语)语言，例如英语.可能需要一些调整才能从句子中仅提取第一个三元组，或者在昏迷的情况下不提取.这是一个非常快速的解决方案，因为浅层POS标记通常为O(n)-每句0.01，而不是深度解析(Open NLP，Stanford Parser)为O(n ^ 3)-每句0.4秒.

The most basic way to do this, with acceptable result is to do shallow parsing and then extracting NOUN-VERB-NOUN triples. This should work for all SVO (subject–verb–object) languages like English. Some tuning may be required to extract only the first triple from a sentence, or not extract in case of comas. It is a very fast solution, because shallow POS tagging usually is O(n) - 0.01 per sentence, instead of deep parsing(Open NLP, Stanford Parser) which is O(n^3) - 0.4 sec per sentence.
