Title Automatic Answer Typing for How-Questions
Venue Human Language Technologies
Session Main Conference
Year 2007

We introduce an answer typing strategy specific to quantifiable how questions. Us- ing the web as a data source, we auto- matically collect answer units appropri- ate to a given how-question type. Exper- imental results show answer typing with these units outperforms traditional fixed- category answer typing and other strate- gies based on the occurrences of numeri- cal entities in text.
