We get significantly higher scores in terms of MRR@150 (from 0.25 to 0.34) and success@10. The 23% improvement that we reach in terms of MRR is comparable to the improvement reached on different QA tasks by other researchers in the field, although our re-ranking approach is based on relatively lightweight overlap measures incorporating syntactic constituents, cue words, and document structure. <\/jats:p>","DOI":"10.1162\/coli.09-032-r1-08-034","type":"journal-article","created":{"date-parts":[[2010,1,29]],"date-time":"2010-01-29T20:35:32Z","timestamp":1264797332000},"page":"229-245","source":"Crossref","is-referenced-by-count":23,"title":["What Is Not in the Bag of Words for <i>Why<\/i>-QA?"],"prefix":"10.1162","volume":"36","author":[{"given":"Suzan","family":"Verberne","sequence":"first","affiliation":[{"name":"* Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"** Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2020 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2021 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lou","family":"Boves","sequence":"additional","affiliation":[{"name":"* Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"** Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2020 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2021 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nelleke","family":"Oostdijk","sequence":"additional","affiliation":[{"name":"* Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"** Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2020 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2021 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter-Arno","family":"Coppen","sequence":"additional","affiliation":[{"name":"* Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"** Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2020 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."},{"name":"\u2021 Department of Linguistics, PO Box 9103, 6500 HD Nijmegen, the Netherlands.."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"p_5","first-page":"132","volume":"4","author":"Charniak E.","year":"2000","journal-title":"ACM International Conference Proceeding Series"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1145\/1147197.1147210"},{"key":"p_17","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4573(88)90021-0"},{"key":"p_25","doi-asserted-by":"publisher","DOI":"10.1145\/219717.219752"}],"container-title":["Computational Linguistics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/coli.09-032-R1-08-034","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:25:26Z","timestamp":1615584326000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/coli\/article\/36\/2\/229-245\/2047"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,6]]},"references-count":4,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2010,6]]}},"alternative-id":["10.1162\/coli.09-032-R1-08-034"],"URL":"https:\/\/doi.org\/10.1162\/coli.09-032-r1-08-034","relation":{},"ISSN":["0891-2017","1530-9312"],"issn-type":[{"value":"0891-2017","type":"print"},{"value":"1530-9312","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,6]]}}}
