However, for languages with complex and ambiguous word-internal structure, known as morphologically rich languages (MRLs), it has been hypothesized that syntactic context may be crucial for accurate MA&amp;D, and vice versa. In this work we empirically confirm this hypothesis for Modern Hebrew, an MRL with complex morphology and severe word-level ambiguity, in a novel transition-based framework. Specifically, we propose a joint morphosyntactic transition-based framework which formally unifies two distinct transition systems, morphological and syntactic, into a single transition-based system with joint training and joint inference. We empirically show that MA&amp;D results obtained in the joint settings outperform MA&amp;D results obtained by the respective standalone components, and that end-to-end parsing results obtained by our joint system present a new state of the art for Hebrew dependency parsing.<\/jats:p>","DOI":"10.1162\/tacl_a_00253","type":"journal-article","created":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T13:04:45Z","timestamp":1554210285000},"page":"33-48","update-policy":"http:\/\/dx.doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":14,"title":["Joint Transition-Based Models for Morpho-Syntactic Parsing: Parsing Strategies for MRLs and a Case Study from Modern Hebrew"],"prefix":"10.1162","volume":"7","author":[{"given":"Amir","family":"More","sequence":"first","affiliation":[{"name":"Open University Ra\u2019anana, Israel. habeanf@gmail.com"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amit","family":"Seker","sequence":"additional","affiliation":[{"name":"Open University Ra\u2019anana, Israel. amitse@openu.ac.il"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Basmova","sequence":"additional","affiliation":[{"name":"Open University Ra\u2019anana, Israel. vicbas@openu.ac.il"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reut","family":"Tsarfaty","sequence":"additional","affiliation":[{"name":"Open University Ra\u2019anana, Israel. reutts@openu.ac.il"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","published-online":{"date-parts":[[2019,3,1]]},"reference":[{"key":"2021060823284273900_bib1","doi-asserted-by":"crossref","unstructured":"Steven P.\n              Abney and \n            \n              Mark\n              Johnson. \n          \n          1991.
