结合案例,从robots协议的语法规则出发,分别讨论了作为搜索条目组成部分的搜索摘要、链接和网页快照的著作权侵权风险问题,论证robots.txt对搜索条目是否构成著作权侵权认定没有直接影响。即使robots.txt禁止被抓取的网页构成作品,但不论是搜索摘要,还是搜索链接,抑或网页快照,认定其构成著作权侵权具有很大的难度。 According to the rules of the robots protocol, this paper discusses the copyright infringement risk of search abstracts, links and web page snapshots as part of search terms respectively.

Even though robots.txt prohibits crawling web pages from constituting works, it is very difficult to determine whether the robots.txt constitutes a copyright infringement, regardless of whether it is a search abstract, a search link, or a webpage snapshot.
