Coverage of Information Extraction from Sentences and Paragraphs

Scalar implicatures are language features that imply the negation of stronger statements, e.g., "She was married twice" typically implicates that she was not married thrice. In this paper we discuss the importance of scalar implicatures in the context of textual information extraction. We investigate how textual features can be used to predict whether a given text segment mentions all objects standing in a certain relationship with a certain subject. Preliminary results on Wikipedia indicate that this prediction is feasible, and yields informative assessments.
