• Einat Minkov
• Andy Schlaikjer
• Laura Kieras

The Problem

• Determine academic institutions with which a
  professor is or has been affiliated
• Where degrees earned
• Previous affiliations, including post-doc
• Current affiliation
• Why would this be useful?
• Studying social networks in academia
• Person entity disambiguation

Knowledge We Will Learn

• Example text rules to be learned
• If string ltpersongt received his ltdegreegt in
  ltdepartmentgt from ltinstitutiongt , Then
  'Affiliated(ltpersongt, ltinstitutiongt)
• If stringltdegreegt , ltdepartmentgt ,
  ltinstitutiongt on ltpersongt s home page,
• Then 'Affiliated(ltpersongt, ltinstitutiongt)'
• Class of beliefs to be learned
• Affiliated(ltpersongt,ltinstitutiongt)

Sources of redundant information

• URL of professors personal home page(e.g.,
  www.cmu.edu/xxx)
• Text found on multiple web pages, especially in
  resume, CV, or biography section of personal home
  pages
• Links incoming and outgoing from personal home
  pages

5
Additional information

• Dictionary of institution names
• Dictionary of degrees
• E.g. Ph.D., B.S., B. Tech., etc
• Map of domain names to institution names
• E.g cmu.edu -gt Carnegie Mellon University
• This could be learned but we will leave that for
  another group!

Bootstrapping Logistics

• Start with a few seed rules and seed facts
• Use these rules to learn more facts, these facts
  to learn more rules, etc etc!

Our seed facts

• Affiliated(ltTom M. Mitchellgt, ltStanford
  Universitygt)
• Affiliated(ltTom Mitchellgt, ltCarnegie Mellon

Our seed rules

• If URL of personal web page is in the academic
  URL dictionary, then believe Affiliated(ltpersongt,

• "ltpositiongt,ltdepartmentgt ltinstitutiongt
• "ltpersongt received ltpronoungt ltdegreegt from
  ltinstitutiongt"

Algorithm walk-through

• Start with known belief Affiliated(William Cohen,
  Duke University)
• Extract sentences from William Cohen web page
  that contain "William Cohen" and "Duke"
• Found pattern "William Cohen received his
  bachelor's degree in Computer Science from Duke
  University in 1984
• Learned new pattern "received ltpronoungt ltdegreegt
  from ltinstitutiongt

10
Walk-through continued

• Search for new web pages matching our pattern
  "received his degree from
• Found example "Adnan Darwiche is an Associate
  Professor of Computer Science at UCLA, having
  received his PhD and MS degrees in Computer
  Science from Stanford University
• Extracted belief Affiliated(Adnan Darwiche,
  Stanford University)
