Start Using ResearchIndex

ResearchIndex is a scientific literature digital library that aims to improve the dissemination and feedback of scientific literature, and to provide improvements in functionality, usability, availability, cost, comprehensiveness, efficiency, and timeliness.

Rather than creating just another digital library, ResearchIndex provides algorithms, techniques, and software that can be used in other digital libraries. ResearchIndex indexes Postscript and PDF research articles on the Web, and provides the following features.

Summary of ResearchIndex
Autonomous Citation Indexing (ACI) ResearchIndex uses ACI to autonomously create a citation index that can be used for literature search and evaluation. Compared to traditional citation indices, ACI provides improvements in cost, availability, comprehensiveness, efficiency, and timeliness. For more details, see Autonomous Citation Indexing.
All cited documents ResearchIndex computes citation statistics and related documents for all articles cited in the database, not just the indexed articles.
Reference linking As with many online publishers, ResearchIndex allows browsing the database using citation links.
Citation context ResearchIndex can show the context of citations to a given paper, allowing a researcher to quickly and easily see what other researchers have to say about an article of interest.
Awareness and tracking ResearchIndex provides automatic notification of new citations to given papers, and new papers matching a user profile.
Related documents ResearchIndex locates related documents using citation and word based measures and displays an active and continuously updated bibliography for each document.
Similar documents ResearchIndex shows the percentage of matching sentences between documents.
Full-text indexing ResearchIndex indexes the full-text of the entire articles and citations. Full boolean, phrase and proximity search is supported.
Query-sensitive summaries ResearchIndex provides the context of how query terms are used in articles instead of a generic summary, improving the efficiency of search.
Citation graph analysis ResearchIndex analyzes the graph of citations, e.g. to provide hubs and authorities ranking (ala Kleinberg).
Page images ResearchIndex allows quick and easy viewing of page images.
Up-to-date ResearchIndex is continuously updated 24 hours a day.
Powerful search e.g. ResearchIndex allows using author initials to narrow a citation search.
Autonomous location of articles ResearchIndex uses search engines and crawling to efficiently locate papers on the Web.
