This could be the reason why bibliometric analyses from CiteSeerx are few in number (Fiala, 2011). As we will see with other autonomous citation indexing systems, their principal drawback is that developments often led to a loss of consistency in the parsing process, and they needed to develop well-defined cleaning processes that solved the malfunctions of these automatic systems. In the case of CiteSeerx, this cleaning process was absent, or it was left to the users to correct the mistakes. 27 This page intentionally left blank 3 Scirus: a multi-source searcher Abstract: This chapter is devoted to the now-retired search engine, Scirus.
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. In this way, CiteSeerx promotes interaction with its users to improve its bibliographic database, perhaps due to the multiple failures of its parsing system, as we will see below (see p. 20). The left-side margin shows the access to the document copies (‘Cached’) hosted in the search engine and the list of URLs (‘Download links’) from where the search engine located the file.
CiteSeerx also includes an advanced search page but its possibilities are rather limited. It enables the user to search in seven metadata fields that describe each record: Text, Title, Author Name, Author Affiliation, Publication Venue, Key Words and Abstract (CiteSeerx, 2013b). These tips support wildcards, double quotes for exact phrases and Booleans queries. However, the tips don’t really search into the metadata content of each record, but into a different index in which some erroneous tags are removed, avoiding the retrieval of inaccurate records.
