Zusammenfassung
This paper presents LiSnQA, a list question answering
system that extracts answers to list queries from the short descriptions
of web-sites returned by search engines, called web snippets. LiSnQA
mines Wikipedia resources in order to obtain valuable information that
assists in the extraction of these answers. The interesting facet of
LiSnQA is, that in contrast to current systems, it does not account for
lists in Wikipedia, but for its redirections, categories, sandboxes, and
first definition sentences. Results show that these resources strengthen
the answering process. In this work, we additionally deal at length with
some findings concerning the distribution of answers to list questions
across the web.
