如何在java中使用spark-corenlp

Question

我在java中实现spark-corenlp时遇到困难。我无法弄清楚java中下面的scala代码的步骤。 spark-corenlp git

scala示例：

function waitForMapLoaded() {
    if(!map.loaded()) {
        window.setTimeout(waitForMapLoaded, 100);
    } else {
        loadData();
    }
}
waitForMapLoaded();

Java：

val input = Seq(
  (1, "<xml>Stanford University is located in California. It is a great university.</xml>")
).toDF("id", "text")
val output = input
  .select(cleanxml('text).as('doc))
  .select(explode(ssplit('doc)).as('sen))
  .select('sen, tokenize('sen).as('words), ner('sen).as('nerTags), sentiment('sen).as('sentiment))

感谢您的帮助。
