1. Methods of discovering ADEs
| Mehods | Description | Pros | Cons |
|---|---|---|---|
| Threshold | Potential ADEs would be recognized once if the bumber of its reports exceeds the threshold | Simplest | Fail to consider the reporters' reliabilty |
| Truth Discovery | Infer the ture information along with learning users' reliability degrees. 2 fundamental questions: single/multiple truth discovery | Tend to discover truth with higher quality |
2. Definition of the ADE discovery problem
(1) Single object: drugs
(2) Multiple claims: users report multiple side-effects
(3) Reporters' quality: platform + user. For user quality, consider both pisitive claims and negative claims, final quality= Quality(users in positive claims) - Quality(users in negative claims)
