Cleaned version of LSQ 2.0

A cleaned version of SPARQL logs information from dumps generated by the Linked SPARQL Queries (LSQ) project. See lsq-clean for description of motivation and methods. Each RDF dump contain information about either queries or their executions on a specific SPARQL endpoint and time interval, following [the original LSQ vocabulary](http://lsq.aksw.org/vocab) visually described [here](http://lsq.aksw.org/v2/concepts/data-model.html).本数据集为关联SPARQL查询（Linked SPARQL Queries，LSQ）项目生成的转储文件中的SPARQL日志信息清理版本。有关该数据集的设计动机与实现方法，请参考lsq-clean相关文档。每个RDF（Resource Description Framework）转储文件均包含特定SPARQL端点与时间区间内的查询信息，或查询执行信息，且遵循[原始LSQ词汇表](http://lsq.aksw.org/vocab)，该词汇表的可视化说明可参见[此处](http://lsq.aksw.org/v2/concepts/data-model.html)。
