The DOI system places basically no useful limitations on what constitutes a reasonable identifier . However, being able to pull DOIs out of PDFs, web pages, etc. is quite useful for citation information, etc. Is there a reliable way to identify a DOI in a block of text without assuming the 'doi:' prefix? (any language acceptable, regexes preferred, and avoiding false positives a must) Alix Axel Ok, I'm currently extracting thousands of DOIs from free form text (XML) and I realized that my previous approach had a few problems, namely regarding encoded entities and trailing punctuation, so I

I was wondering if it is possible to "automate" the task of typing in entries to search forms and extracting matches from the results. For instance, I have a list of journal articles for which I would like to get DOI's (digital object identifier); manually for this I would go to the journal articles search page (e.g., http://pubs.acs.org/search/advanced ), type in the authors/title/volume (etc.) and then find the article out of its list of returned results, and pick out the DOI and paste that into my reference list. I use R and Python for data analysis regularly (I was inspired by a post on
