Research Index (also known as CiteSeer) : The NECI Scientific Literature Digital Library

ResearchIndex is a free citation index for computer science and technology disciplines. It uses search engines to locate papers on the Web, indexes the paper including the citations. Papers indexed includes technical reports, conference proceedings as well as literature in "Postscript" and "PDF" formats.

It allows :

• searching for articles by keyword, title or author
• Computes citation statistics and related documents for all articles cited in the database, not just the indexed articles.
• Access to full text articles

Begin

Go to http://citeseer.comp.nus.edu.sg/cs to access this database hosted at NUS School of Computing.

Search Documents This is a search for the words in the author, document title, full text of articles, abstract, keywords or the Meta information. Enter the term or phrase, for example sfx. Use AND when all the terms must appear and may be far apart from each other. Example: blue and tooth Use OR when at least one terms must appear. Example: blue or tooth Use w/#, when # is the number of word within the 2 terms. Example: blue w/10 tooth, blue within 10 words of tooth in any order.

The Results List

By default, articles that have been cited the most would be displayed first. Order by Hubs, to list the papers containing the most external links first. Click on # citations, to view the list of documents that have cited the article. Click on Correct, to submit any corrections regarding a particular document. Click on the first record and it will give the following detailed result, shown partially.

The Detailed Record

View or Download, is the link to the document in its original format At Cached, just select the desired format of the document you wish to view or download. At From, are links to the original page on which the document was found. At Homepages. are links to the current document authors' hompages which could be useful in locating more materials, opinions and theories of these authors. Click on Home/Search if you want to do another search. Click on Bookmark if you wish to return to the record in the future. Click on Context will display the articles that have cited the current document and context of citations in those articles (shown in the detailed record) where the reference was made.

Click on Context and will list these all articles from these hosts that have cited this current document. The figures in the brackets is a prediction in CiteSeer as self-citations. To view articles that are predicted as self-citations, click on Doc The graph shows the number of citations (excludes all self-citations) against the year of publication for each cited article.
