CiteSeerX is a crawl-based digital library search engine providing free access to more than 4 million academic papers. Since metadata in the digital library is obtained through automatic extraction, it is inevitable that errors will occur. CiteSeerX offers a feature allowing registered users to correct paper metadata including titles, authors, abstracts, publication years, venues, etc. We claim that user corrections, as a form of crowd-collaboration, provide a useful and efficient way to improve metadata quality and the impact of the digital library. As evidence to support this claim, we investigate user corrections from the last 5 years and analyze: the nature of the corrections; the quality of the corrections; and the impact of the corrections on downloads.<\/p>\n","protected":false},"excerpt":{"rendered":"
