Abstract

Autonomous Citation Indexing (ACI) automates the construction of citation indexes - Lower cost, wider availability: ACI is completely autonomous - no manual effort is required. This should result in lower cost and wider availability. Broader coverage: Because no manual effort is required, there are few barriers to indexing a broader range of literature, compared to indexes like the Science Citation Index that require manual effort. More timely feedback: Conference papers, technical reports, and preprints can be indexed, providing far more timely feedback in many cases (often such publications appear far in advance of corresponding journal publications). Citation context: ACI groups together the context of citations to a given article, allowing researchers to easily see what is being said and why the article was cited. Benefits for both literature search and evaluation. Freely available: Our implementation of ACI is available at no cost for non-commercial use. Several orgnizations have requested the software and expressed interest in providing an index within their domain, or in using ACI within their own digital libraries.
