Sample text

This provides distinct rankings of items by citations. The documents and citations rankings can be complete (for all years) or limited by year from 1990 to 2013. Unlike document ranking, the citations ranking contains the mostcited documents not included in CiteSeerx. However, the number of citations provided does not match the total amount presented in the document page due to the variable updating rates between the lists and the general database, a fact that is noted in each ranking.

However, although CiteSeerx can be considered to be a pioneer in academic searching, at the present time it has lost the initiative and has not been able to keep pace with recent developments in the market. CiteSeerx is a product designed by scientists for scientists and its most important contribution to the academic searching environment was the development of automated citation indexing, allowing the creation of an autonomous citation index.

For example, Social and Behavioral Sciences might contain documents from Psychology and from Sociology; similarly, Life Sciences was related to both Agricultural and Biological Sciences and Environmental Sciences. Another significant problem was that there was no Arts & Humanities classification, which meant that documents about history, literature or the arts could not be retrieved, although they were indeed included.
