使用 Gate 进行日志记录

Question

我是 Java 和 Gate 的新手，所以我将提供详细的步骤。我试图在我的 java 应用程序中使用 Stanford pos tagger，但它给了我这个错误：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Reading POS tagger model from file:/home/khaled/smartgit/projects/MicroblogsAnnotator/GATE_Developer_8.4.1/plugins/Stanford_CoreNLP/resourcs/english-left3words-distsim.tagger ... done [2.6 sec].

这里的另一个问题是我下载了 "slf4j-log4j12.jar" 并试图将其包含在我的 class 路径中。我不确定这是否是添加它的正确方法，但是我从 netbeans 中单击了

project->Properties->Libraries->add Jar

运行现在又给了我另一个错误：

Answer 1

您快完成了，您还需要包括 slf4j-api.jar。

然后可能需要一个 log4j 配置文件，以防你还没有...

使用 Gate 进行日志记录
