Abstract
How-questions are difficult to answer automatically, since the answers are usually not available in form of a single string in a technical document but need to be constructed from various information located at different places in the document or even from external knowledge sources.
In this paper, we show how procedural questions can be answered in the context of ExtrAns.
ExtrAns is an answer extraction system and operates over technical documentations that are rich in procedural knowledge. This procedural knowledge is often expressed in a procedural writing style that follows more or less strict guidelines. These guidelines together with typographical
conventions can be exploited in a systematic way to first construct and then extract informative answers to procedural questions.
