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 (also known as CiteSeer)
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.
Freely available
The full source code of ResearchIndex is available at no cost for non-commercial use.
