This implies that around half of them are usually not associated to drug treatment options. Regarding the false positives (see Table two), the principle supply of errors is the lack of context resolution. This means that, regardless of appropriately detecting a drug and an effect (based on the drug package insert), the context from the text did not fulfill the needs to properly contemplate it a relation.
