gAnwer运行正确，我用的是浏览器进行http请求，输出结果是{"question":"who is the wife of Donald Trump?","message":"InvalidQuestionException: the question you input is invalid, please check","status":"500"}，日志如下：

我http请求的输入是
http://localhost:9999/gSolve/?data={maxAnswerNum:3,needSparql:1,question:who%20is%20the%20wife%20of%20Donald%20Trump?}

您好！这里是因为dbpedialookup它更新成https访问了，gAnswer中原来的访问方法无法处理https，我们正在着手修改这部分的代码。如果您急需使用的话，您可以在本地自己建一个dbpedialookup，您可以发一封邮件到我的邮箱linyinnian@pku.edu.cn 我可以把相关文件发给您。

好的，谢谢，因为我需要中文知识问答，然后我就避开了dbpedialookup的问题，但是现在我在测试中文问答的源码时，发现输出结果为：{"question":"北京奥运会的口号是什么？","vars":["?口号"],"sparql":["select DISTINCT ?口号 where { <2008年北京奥运会>\t<口号>\t?口号. } LIMIT 3"],"results":{"bindings":[]},"status":"200"}
输出日志为：

这是不是因为您那边服务器服务没开？？？，因为我这边没有建立本地的gStore库

[nicklin96]

这两天一直有个脚本在发送导致重启的查询，我们正在处理~ 建议的话还是本地建一个比较稳定~

您好，能否提供一个相对较小的pkubase triples文件，我这边想构建本地gStore库，但是您之前提供的文件太大了，我现在只是想跑通您的这个gAnswer问答系统。
