Embedding citation metadata in the ADS HTML

March 1st, 2010

Here’s what I know: you can embed a set of <meta/> tags containing citation metadata in your HTML to help Google Scholar to index your content. We’ve been doing it at ADS for quite a while. I’m not certain if the impetus came directly from Google, or, more likely, we got the idea from a CrossTech blog post by Tony Hammond that describes the technique.

For example, if you execute  curl -s http://adsabs.harvard.edu/abs/1977NuPhB.126..298A | grep meta you should see:

...
<meta name="citation_language" content="en" />
<meta name="citation_doi" content="10.1016/0550-3213(77)90384-4" />
<meta name="citation_abstract_html_url" content="http://adsabs.harvard.edu/abs/1977NuPhB.126..298A" />
<meta name="citation_title" content="Asymptotic freedom in parton language" />
<meta name="citation_authors" content="Altarelli, G.; Parisi, G." />
<meta name="citation_issn" content="0550-3213" />
<meta name="citation_date" content="08/1977" />
<meta name="citation_journal_title" content="Nuclear Physics B" />
<meta name="citation_volume" content="126" />
<meta name="citation_firstpage" content="298" />
<meta name="citation_lastpage" content="318" />
...

Since first implementation we’ve had some back-and-forth with Abhishek Jain at Google Scholar to ensure we’re making use of the full set of fields that Google Scholar looks for.*

Dan Chudnov, David Bucknum & Ed Summers at the LoC recently expressed interest in also embedding these tags. In the absence of official reference from the Google Scholar folks, I figured it would be a good thing to post here.

  • citation_language
  • citation_doi
  • citation_abstract_html_url
  • citation_title
  • citation_authors
  • citation_issn
  • citation_date
  • citation_journal_title
  • citation_volume
  • citation_firstpage
  • citation_lastpage
  • citation_publisher
  • citation_issue
  • citation_pdf_url
  • citation_pmid
  • citation_keywords (multiple instances OK)
  • citation_conference
  • citation_dissertation_name
  • citation_dissertation_institution
  • citation_patent_number
  • citation_patent_country
  • citation_technical_report_number
  • citation_technical_report_institution

I had to cull this list via a visual scan of a long, forwarded e-mail thread. So, like I tried to insinuate above, it sure would be great if Google Scholar would publish an official reference to this schema somewhere.

* all instances of the term “we” should really be read as “my boss, Alberto”.

Contextual Inquiry on the Cheap

December 31st, 2009

I thought I’d share the interview outline I’ve been using to conduct some low effort contextual inquiry sessions with ADS users.

Classic contextual inquiry, in which the researcher sits with or shadows a person in the context of the subject’s own working environment, is often conducted in 3+ hour sessions, frequently with all manner of video capturing equipment. My goal is cut that time down to 30 minutes, partly because this whole user research thing is supposed to be a part-time endeavor, and also because the majority of ADS users are PhD’s, and we all know just how valuable their time is.

So far I’ve only managed to conduct four of these interviews (with two more scheduled). Would love to get a total of 10. Since I don’t have access to video equipment I simply mash out typewritten, poorly spelled notes as fast I can. The notes have a stream of consciousness flavor, but the early indications are that the information gathered will be valuable.

Example notes:

refers to bibcode as "indexing thing". "not any use to me."
wrote a perl script that rewrites the bibcode into something understandabl
other strategies for searching for particular star: entering star name into abstract search or title search.
finds one article using abstract search.
mentions that he doesn't know boolean sytnax by memory
to find more tries going to simbad and finds alternate names for the star
