使用 Apache Jena Fuseki 我正在尝试从Wikidata加载 latest-truthy.nt 数据集，但在尝试导入文件时出现以下错误。受到来自Bitplan的以下成功的启发，他们确实取得了成功。

错误日志：

导入脚本：

@ECHO off
cd apache-jena-4.0.0
echo start import on %DATE% %TIME%

tdb2_tdbloader --loader=parallel --loc "C:\fuseki\data" "F:\latest-truthy.nt" > tdb2-out.log 2> tdb2-err.log

echo finish import on %DATE% %TIME%
pause

文件结构：

- C:/fuseki/
-- apache-jena-4.0.0/
-- apache-jena-fuseki-4.0.0/
-- data/
-- startfusekidb.bat
-- wikidata2fuseki.bat

- F:/
-- latest-truthy.nt

这是Fuseki的问题吗？我无法自己打开 .nt 文件来解决问题。有没有我可以使用的标志，所以它跳过了使用 tdbloader 对给定导入的验证？

我也在 Wikidata 的 IRC 频道中询问这个问题，看看他们是否可以帮助我。

更新：我得到了 IRC 某人的回答，他们告诉我数据集中存在很多错误 Wikidata中的错误所以我知道需要找到一种方法来跳过与错误相关的行并继续加载。但是Fuseki TDB2 命令没有显示任何帮助。

还尝试 --help 输出以下内容，从而表明不存在跳过？

@NLxDoDge - 感谢您指出我的 BITPlan 成功故事。实际上，wikidata nt 转储可能包含与 Jena 4.1 不兼容的三元组导入 - 我今天在人类住区的https://wdumps.toolforge.org/dump/1607遇到了类似的问题。

一个三元组：

<http://www.wikidata.org/entity/Q992883> <http://www.wikidata.org/prop/direct/P856> <http://www.sonora.gob.mx/portal/Runscript.asp?p=ASP\\pg239.asp> .

会破坏节目给出错误：

10:45:06 ERROR riot            :: [line: 6964090, col: 139] Illegal unicode escape sequence value: \\ (0x5C)
org.apache.jena.riot.RiotException: [line: 6964090, col: 139] Illegal unicode escape sequence value: \\ (0x5C)

我只是编辑了 1.2 GB wdump-1607.nt 文件 vim，您可以在其中使用

:6964090

然后保存文件

:wq!

在尝试 wikidata 完全导入之前，您可能希望使用这个 100 MB 的小转储文件来尝试您的环境，最终需要 >2TB 的SSD！工作的磁盘空间。

请在下面找到我用于导入转储和启动 fuseki 服务器的脚本。

你应该得到类似的结果
