我一直试图在演示PDF中使用IBM Watson文档转换服务，但它并没有将文档转换成小块。它所做的只是创建一个答案单元，这真的很长：
"text": "Watson is an artificially intelligent computer system capable of answering questions posed in natural language,[2] developed in IBM's DeepQA project by a research team led by principal investigator David Ferrucci. Watson was named after IBM's first CEO and industrialist Thomas J. Watson.[3][4] The computer system was specifically developed to answer questions on the quiz show Jeopardy![5] In 2011, Watson competed on Jeopardy! against former winners Brad Rutter and Ken Jennings.[3][6] Watson received the first place prize of $1 million.[7] Watson had access to 200 million pages of structured and unstructured content consuming four terabytes of disk storage[8] including the full text of Wikipedia,[9] but was not connected to the Internet during the game.[10][11] For each clue, Watson's three most probable responses were displayed on the television screen. Watson consistently outperformed its human opponents on the game's signaling device, but had trouble responding to a few categories, notably those having short clues containing only a few words. In February 2013, IBM announced that Watson software system's first commercial application would be for utilization management decisions in lung cancer treatment at Memorial Sloan- Kettering Cancer Center in conjunction with health insurance company WellPoint.[12] IBM Watson's former business chief Manoj Saxena says that 90% of nurses in the field who use Watson now follow its guidance.[13]"
提前感谢！
不幸的是，该演示PDF并不是最好的文档：目前，Answer Units是根据标题标签（h1-h6）进行拆分的，并且该PDF不包含任何标题=（
如果将conversion_target设置为NORMALIZED_HTML，则在将转换后的PDF拆分为"应答单元"之前，您将能够看到它。它将包含段落，但不包含标题。
在未来，我们预计也会允许按段落划分答案单元，但这还没有发布。
更新：我们用一个更好的例子更新了演示网站上的PDF。
