The parsing strategies differ in terms of the order in which they recognize productions in the derivation tree, where bottom-up strategies and top-down strategies take post-order and pre-order traversal over trees, respectively. Bottom-up parsers benefit from rich features from readily built partial parses, but lack lookahead guidance in the parsing process; top-down parsers benefit from non-local guidance for local decisions, but rely on a strong encoder over the input to predict a constituent hierarchy before its construction. To mitigate both issues, we propose a novel parsing system based on in-order traversal over syntactic trees, designing a set of transition actions to find a compromise between bottom-up constituent information and top-down lookahead information. Based on stack-LSTM, our psycholinguistically motivated constituent parsing system achieves 91.8 F<jats:sub>1<\/jats:sub> on the WSJ benchmark. Furthermore, the system achieves 93.6 F<jats:sub>1<\/jats:sub> with supervised reranking and 94.2 F<jats:sub>1<\/jats:sub> with semi-supervised reranking, which are the best results on the WSJ benchmark. <\/jats:p>","DOI":"10.1162\/tacl_a_00070","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T15:42:50Z","timestamp":1546011770000},"page":"413-424","source":"Crossref","is-referenced-by-count":23,"title":["In-Order Transition-based Constituent Parsing"],"prefix":"10.1162","volume":"5","author":[{"given":"Jiangming","family":"Liu","sequence":"first","affiliation":[{"name":"Singapore University of Technology and Design, 8 Somapah Road, Singapore,                         487372,"}]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[{"name":"Singapore University of Technology and Design, 8 Somapah Road, Singapore,                         487372,"}]}],"member":"281","reference":[{"issue":"4","key":"p_15","first-page":"613","volume":"24","author":"Johnson Mark","year":"1998","journal-title":"Computational Linguistics"},{"key":"p_16","doi-asserted-by":"publisher","DOI":"10.1162\/tacl_a_00101"},{"key":"p_19","doi-asserted-by":"publisher","DOI":"10.1162\/tacl_a_00045"},{"issue":"2","key":"p_20","first-page":"313","volume":"19","author":"Marcus Mitchell P.","year":"1993","journal-title":"Computational Linguistics"},{"key":"p_26","doi-asserted-by":"publisher","DOI":"10.1162\/coli.2010.36.1.36100"},{"issue":"2","key":"p_36","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1017\/S135132490400364X","volume":"11","author":"Xue Naiwen","year":"2005","journal-title":"Natural Language Engineering"}],"container-title":["Transactions of the Association for Computational Linguistics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/tacl_a_00070","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:38:14Z","timestamp":1615585094000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/tacl\/article\/43405"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,12]]},"references-count":6,"alternative-id":["10.1162\/tacl_a_00070"],"URL":"https:\/\/doi.org\/10.1162\/tacl_a_00070","relation":{},"ISSN":["2307-387X"],"issn-type":[{"value":"2307-387X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,12]]}}}
