我想在 java 命令行中使用 stanford-parser-full-2015-01-30

Question

当我使用这个命令时

java -mx100m edu.stanford.nlp.trees.EnglishGrammaticalStructure -sentFile input.txt -collapsedTree -CCprocessed -parseTree -parserFile englishPCFG.ser.gz it return this Error: unable to find or load main class edu.stanford.nlp.trees.EnglishGrammaticalStructure

当我使用这个命令时

java -cp "*" edu.stanford.nlp.trees.EnglishGrammaticalStructure -sentFile input.txt -collapsedTree -CCprocessed -parseTree -parserFile englishPCFG.ser.gz it retruns

我不知道问题出在哪里以及如何使用这个库

Answer 1

您必须在命令中提供资源的完整路径。

edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz

当 Java 尝试查找某些内容时，它会在 CLASSPATH 中的所有 jar 文件中查找该路径。此外，-cp "*" 只有在包含所有 .jar 文件的目录中执行命令时才会起作用。
