h: 'X invented the PC' for "Who invented the PC?").
h should not be matched in "Engineers demonstrated the new system", due to a mismatch between the intended sense of 'demonstrate' in h and its sense in t. Similarly, when looking for physical attack mentions using the hypothesis 'X attack Y ', we should not utilize the rule r: 'X accuse Y → X attack Y ', due to a mismatch between a verbal attack in r and an intended physical attack in h. Finally, r: 'X produce Y → X lay Y ' (applicable when X refers to poultry and Y to eggs) should not be matched in t: "Bugatti produce the fastest cars", due to a mismatch between the meanings of 'produce' in r and t. Overall, such incorrect inferences may be avoided by considering contextual information for t, h and r during their matching process.
