Meeting Minutes

Meeting with Rafael Calvo, Robert Dale
  • Academic Paper: Thumbs Up or Thumbs Down? Semantic Orientation Applied to Unsupervised Classification of Reviews, P.D Turney, July 2002
  • Much work has been done in the past on sentiment in product/movie reviews, but these may not transfer to the domain of finance, and some finance domain knowledge is necessary in analysis.
  • AFR Titles may tend to be more extreme (sensationalized) in relation to their actual content
  • Necessary to find sources of positive/negative related terms, and how well they correlate with the data set/annotations and vise versa.
  • May not be able to be done on word frequency count alone (taking out company name, terms such as the, a etc).
  • Could use synonym trees to help with the large term set (lexical database such as WordNet)
  • Found information on some research done in this area by Sirca
  • Interesting abstract and presentation given by C Robertson: "Enabling Sophisticated Financial Text Mining"
