dbpedia spotlight数据集

Question

在接下来的dbpedia spotlight dataset中，我按照说明更新了我的数据集，但得到了以下错误：

INFO 2012-06-19 11:58:04,300 main [MergedOccurrencesContextSearcher] - Using index at: org.apache.lucene.store.MMapDirectory@/home/user_name/new/spotlight/index lockFactory=org.apache.lucene.store.NativeFSLockFactory@671381e7

我已经能够成功地使用spotter字典，但不能使用索引文件。

你能帮帮我吗？

Answer 1

在没有足够信息的情况下很难帮助你。该消息抱怨文件不在那里。文件在那里吗？目录在那里吗？

请粘贴ls -lah /home/user_name/new/spotlight/index命令的结果
