A lightweight extraction method derives text snippets associated to dates from the Web. The snippets are organized dynamically into answers to de nition questions. Experi- ments on standard test question sets show that temporally-anchored text snippets allow for ef ciently answering de nition ques- tions at accuracy levels comparable to the best systems, without any need for complex lexical resources, or specialized processing modules dedicated to nding de nitions.
