  2. Outline • Motivation • Objective • Methodology • Experiments • Conclusion • Comments

  3. Motivation • In the past, studies mainly focussed on identifying customers' sentiment polarities toward products. The most important problem in CI—i.e., collecting and analyzing the competitors' information to identify potential risks as early as possible and plan appropriate strategies—has not been well studied. • Users usually prefer to compare several competitive products with similar functions.

  4. Objective • To propose a novel approach to extracting product comparative relations from customer reviews, and display the results as comparative relation maps for decision support in enterprise risk management. V.S. iPhone beats the curve in both function and looks.

  5. Methodology R (P1; P2; A; S) Product Sentiment Attribute Sentiment Attribute Product The iPhone has better looks, but a much higher price than the BBCurve “BlackBerry 8320” is written as “BB 8320” and “8320”.

  10. Conclusion(1/2) • MAJOR CONTRIBUTION • The proposed graphical model can achieve better performance for relation extraction by modeling the unfixed interdependencies among relations, which is not covered by the existing methods. • To the best of our knowledge, this is the first work on using comparison opinion as information sources in CI for enterprise risk management. • The empirical evaluation shows that the performance of the comparative relation extraction is quite promising, and it implies the feasibility of mining the comparison opinions for CI. • FUTURE WORK • To conduct an empirical evaluation of the proposed model on a larger scale with other product types.

  11. Conclusion(1/2) • FUTURE WORK • To extend the model to jointly recognize the comparative relations and entities so as to reduce the errors accumulated in the pipeline process.

  12. Comments • Advantage • This paper describes very clearly. • Application • CRM
