[open-science] fyi - Using OpenCV & Tesseract open source OCR for equation recognition

Mon Feb 4 20:23:17 UTC 2013

Bryan,

Could you elaborate a bit?  What kind of information do you have to base
the query on, and what data do you want to get out?

You might find Greycite (http://greycite.knowledgeblog.org/) useful
(through its API, I think source-code is also available).  The CrossRef API
is pretty useful: http://api.labs.crossref.org/, particularly if you
already have the DOIs.  A good number of publishers have their own API for
all their data (PLoS: http://api.plos.org/) or at least the metadata
(Nature: http://developers.nature.com/docs/read/APIs), and most publishers
follow the Google Scholar/highwire convention for html metadata
http://scholar.google.com/intl/en-US/scholar/inclusion.html#indexing, which
any open source html/xml parser could help extract.  Sorry if this is old
news and you have something more elaborate in mind.

Cheers
