Hello, When I try to segment Chinese document on Windows 10 system with script: bash topictilling.bat -ri 5 -tmd topicmodel -tmn model-final -fp "*txt" -fd files_to_segment I encounter the following error Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/IllegalClassException at org.uimafit.factory.CollectionReaderFactory.createDescription(CollectionReaderFactory.java:217) at org.uimafit.factory.CollectionReaderFactory.createDescription(CollectionReaderFactory.java:208) at org.uimafit.factory.CollectionReaderFactory.createCollectionReader(CollectionReaderFactory.java:154) at org.uimafit.factory.CollectionReaderFactory.createCollectionReader(CollectionReaderFactory.java:118) at de.tudarmstadt.langtech.semantics.segmentation.segmenter.RunTopicTilingOnFile.(RunTopicTilingOnFile.java:102) at de.tudarmstadt.langtech.semantics.segmentation.segmenter.RunTopicTilingOnFile.main(RunTopicTilingOnFile.java:94) Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang.IllegalClassException at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 6 more What does this error mean?

Before execute topictilling, I execute JGibbLDA with command java -cp bin:lib/args4j-2.0.6.jar jgibblda.LDA -est F:\JGibbLDA-v.1.0\model\ -dfile 01.txt and get five model-final files. Did I do anything wrong?
