Data Mining Dissertations and Adventures and Experiences in the World of Chemistry

Published on

This presentation was given at the CLIR/DLF Postdoctoral Fellowship Summer Seminar at Bryn Mawr college in Pennsylvania on July 29th 2014. The intention was to communicate what we are doing in the fields of text and data mining in the domain of chemistry and specifically around mining the RSC archive publication and chemistry dissertations and theses. How would these experiences map over to the humanities?

  • Can easily spot titles, authors, abstract, headings
  • In this case, the OCR used by the scanning organisation couldn’t cope with inderlined titles, and the context pointers were ost
  • This should be a single node, a noun. But because of the punctuation in the chemical name, the Stanford parser, which is very good but trained on the Wall Street Journal, has interpreted it as a huge baroque sentence.
  • Not sure who the audience for this will be but worth mentioning if there’s a humanities audience.

    36. 36. Questions to ask: (1)Has someone already produced an ontology covering your area? (Places to look: Bioportal, OBO Foundry.) (2)Do they take requests? (3)Are they responsive? (4)Is the ontology kept up to date? Early days for ontologies and any ontology will almost certainly be a long way from complete! Best practices: experiences from biomedical ontologies
    37. 37. • Best that these don’t change • Best that everyone calls them the same things • Best that they are unambiguous • Meanwhile, back in the real world What things are you looking for?
    38. 38. • Place names – somewhat ambiguous • Species names – can change with time • Diseases – every pharmaceutical company has a different list • People – can be very ambiguous: Authors and researchers are hard to map…except for Google it seems! How easy?

    51. 51. Tinman - mutant fly embryos lack a heart. Van Gogh - hair-like bristles on wings have a swirling pattern. INDY - acronym for I'm Not Dead Yet, they live twice as long as normal; from the scene in the movie "Monty Python and the Holy Grail" Ken and Barbie - males and females lack external genitalia. Tribbles - some cells divide uncontrollably Cheap date - flies are extra-sensitive to alcohol. Cleopatra - flies die when Cleopatra gene interacts with another gene, Asp. Kojak - no hairs on wings. Maggie - fly development is arrested; named after Maggie Simpson, who's development also seems to be arrested.

Allegedly from “Celestial Emporium of Benevolent Knowledge” The Analytical Language of John Wilkins, Jorge Luis Borges Animal classification
    53. 53. • Are you just identifying entities? • Are you looking for sentiment? • In chemistry names will lead you to a recipe for synthesis, and analytical data about that compound Classification after “things”

    55. 55. • Automation can give good results • Especially looked at in bulk • Less easy to judge at the article level • People accept discovery is fuzzy • Not so with data points • (but maybe can screen out) Quality
    56. 56. • Chemical names are both difficult and rewarding. • Difficult in the sense that they can break standard software. • Rewarding in the sense that you can extract useful information about the molecule they’re referring to without a dictionary. • Some examples… Chemistry-specific challenges and opportunities
