All aboard the Semantic Bandwagon

  1. 1. All aboard the semantic bandwagon… … hold on a moment Colin Batchelor 20101202
  2. 2. What do people mean by semantics? <ul><li>Semantic web </li></ul><ul><li>Specifying how web service shall speak unto web service </li></ul><ul><li>Natural-language semantics </li></ul><ul><li>Lexical semantics </li></ul><ul><li>Compositional semantics </li></ul>
  3. 3. What do search engines do? <ul><li>Words stand only for themselves (Sp ä rck-Jones) </li></ul><ul><li>You shall know a word by the company it keeps (Firth) </li></ul><ul><li>Search engines don’t use semantic methods. </li></ul>
  4. 4. Statistics versus semantics <ul><li>A counterblast: </li></ul><ul><li>Alon Halevy, Peter Norvig and Fernando Pereira, “ The Unreasonable Effectiveness of Data ”, Intelligent Systems , 2009, 24 , 8. </li></ul><ul><li>But STM publishers don’t just publish text. </li></ul>
  5. 5. Beyond text <ul><li>Data which doesn’t come in sentences: </li></ul><ul><li>Tables in articles </li></ul><ul><li>Microarray data </li></ul><ul><li>Experimental protocols </li></ul><ul><li>Crystallographic data </li></ul><ul><li>Chemical structures </li></ul>
  6. 6. The case for chemical markup There are very well established and understood methods for indexing and searching chemical structures. Chemical structures are the chief route into the literature for many chemists. We can extract chemical structures at least semi-automatically from: Molecule names Author-supplied graphics
  7. 7. 5 questions for you <ul><li>What could you achieve through “letting words stand for themselves”? </li></ul><ul><li>What do you hope to achieve through semantic markup? </li></ul><ul><li>What kinds of non-textual data do you have access to? </li></ul><ul><li>What can you do with your non-textual data? </li></ul><ul><li>What external resources could be opened to your readers? </li></ul>
  8. 8. Any questions for me?
