Sample text

Introduced by Elsevier in 2000 it was the first academic search engine that mixed up authoritative sources such as publisher platforms and open access repositories with a deep crawl of academic web pages. It also presented a complete search interface with an advanced filtering system that allowed the user to analyse their most relevant sources and their indexing problems. Its principal weaknesses were its poor duplication control – producing several entries for the same document or webpage, and its classification inconsistencies – producing many materials without a subject matter.

These facts allow us to claim that CiteSeerx really is a specialized computing and information science search engine, although it does host documents from other disciplines as well. 2). This is because CiteSeerx is also a digital library that stores documents that it locates on the web. Each record contains, firstly, information that identifies the file, such as title, publication year, author, venue and number of citations from CiteSeerx. Secondly, on the left side, a box is presented that displays several functions describing what users can do with the record, such as: save it; add it to any personal collections; suggest any corrections and monitor the changes in the record.

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. At the time of writing, the ‘Venue Impact Rating’ was not working, so I cannot discuss what information it contains nor what its validity is.
