ParaCite – Powerful System for Reference Parsing and Location
http://paracite.eprints.org/

ParaCite is an experimental service, being designed at the University of Southampton, for the location of articles from raw references. When a reference is passed to the service, it is split into its component parts (e.g. author, title, year), and transferred to the search resource. Based on the subject area, and the data provided, a set of resources is presented that the system believes have the highest probability of providing the full text article at no charge. The reference parsing is currently achieved using a custom built reference handler. This uses a chain of regular expressions, combined with a set of templates for common reference styles. The parser is still in an experimental status, but once it is stable they plan to release the Perl modules as open source. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
