The Depling 2017 conference in Pisa is the fourth meeting in the recently established series of international conferences on Dependency Linguistics which started in Barcelona in 2011 and continued in Prague and Uppsala in 2013 and 2015, respectively. The initiative to organize special meetings devoted to Dependency Linguistics, which is currently at the forefront of both theoretical and computational linguistics, has received great support from the community. We do hope that the present conference will manage to keep up the high standards set by the previous meetings.
This year we received 41 submissions by 93 authors from 27 countries, one of which was withdrawn before reviewing. Of the remaining 40 submissions (each reviewed by 3 members of the Program Committee), 30 were accepted, resulting in an acceptance rate of 75%. All in all, the proceedings contain a wide range of contributions to Dependency Linguistics, ranging from papers advancing new theoretical models, through empirical studies of one or more languages, as well as experimental investigations of computational systems of dependency parsing and linguistic knowledge extraction, to the design and construction of dependency-based linguistic resources (both treebanks and lexicons) for a wide range of languages.
New to Depling 2017 edition is the fact that the conference is held in conjunction with the biennial meeting of SIGPARSE, namely the International Conference on Parsing Technologies (IWPT 2017), organized by the Special Interest Group on “Natural Language Parsing” of the Association for Computational Linguistics (ACL). IWPT 2017 will take place immediately after Depling 2017, from the 20th to 22nd of September 2017. The two conferences have an overlapping event, held on September 20th and focusing on different aspects of dependency parsing, in which the results of a shared task jointly organized by Depling and IWPT are presented and discussed from different and complementary perspectives.
The shared task, named “Extrinsic Parser Evaluation” (EPE) and playing the role of “bridge event” between the two conferences, is aimed at shedding light on the downstream utility of various dependency representations (at the available levels of accuracy for different parsers), that is, to seek to contrastively isolate the relative contributions of each type of representation (and corresponding parsing systems) to a selection of state-of-the-art systems (which use different types of text and exhibit broad domain and genre variation).
In addition to the accepted papers, the core conference program also includes the contribution of two distinguished keynote speakers, Yoav Goldberg (Bar Ilan University) and Eva Hajicová (Charles University in Prague). We are honoured that they accepted to contribute to Depling 2017 and thank them for agreeing to share their knowledge and expertise on key Dependency Linguistics topics with the conference participants.
Our sincere thanks go to the members of the Program Committee who thoroughly reviewed all the submissions to the conference and provided detailed comments and suggestions, thus ensuring the quality of the published papers. Many thanks to the members of the Local Organizing Committee who took care of all matters related to the local organization of the conference. Thanks are also due to Michela Carlino, who did a great job in putting the proceedings together, and to Chiara Mannari, for designing and constructing the Depling and IWPT+Depling conference websites and continuously updating them. Last but not least, we would like to acknowledge the support from endorsing organizations and institutions and from our sponsors, who generously provided funds and services that are crucial for the organization of this event. At the time of writing, Depling was sponsored by the newly founded “Italian Association of Computational Linguistics” (AILC) and by the University of Pisa. Special thanks are also due to the Institute for Computational Linguistics “Antonio Zampolli” of the Italian National Research Council (ILC-CNR) for the support in the organization of the event. Thanks finally to everyone who chose to submit their work to Depling 2017, without whom this volume literally would not exist.
We welcome you all to Depling 2017 in Pisa and wish you an enjoyable conference!
