Dear Colleagues,

The 8th Language and Technology Conference (LTC 2017), a meeting organized by the Faculty of Mathematics and Computer Science of the Adam Mickiewicz University, Poznań, Poland and the Adam Mickiewicz University Foundation, will take place on November 17-19, 2017. Following the tradition of the past events, it is supported by ELRA, FlaReNet, and META-NET.

Yes, we started 22 years ago! Our tradition goes back to the Language and Technology Awareness Days, a meeting organized in 1995 with the assistance of the European Commission (DG XIII). Among the key speakers were Antonio Zampolli (Italy), Dafydd Gibbon (Germany), Dan Tufiş (Romania), Orest Kossak (Ukraina). Today, we refer to this event as the first LTC. Ten years later, we decided to meet again, and since then the conference is being organized every two years as the “Language & Technology Conference: Human Language Technologies as a Challenge for Computer Science and Linguistics”.

Since the very beginning (1995) the meetings of the LTC series continue to address Human Language Technologies (HLT) as a challenge for computer science, linguistics and related fields. Fostering language technologies and resources remains an important objective in our dynamically changing information-saturated world that motivate us to invite you for joining us at the LTC 2017 in Poznań.

Chris Cieri

Executive Director, Linguistic Data Consortium,University of Pennsylvania,3600 Market Street, Philadelphia, PA. 19104 Penn State University, USA

BIO: Christopher Cieri’s interests lie at the intersection of language, large data, and computation. He received his PhD in Linguistics from the University of Pennsylvania where he focused on sociolinguistics, language contact, phonetics, phonology and morphology. He has worked since 1983 applying technology to linguistic analysis and language teaching using data sets that are too large to process with purely human effort. Cieri became the Executive Director of the Linguistic Data Consortium in 1998 and has since been responsible for overseeing all aspects of the Consortium’s operations including the publication of over 500 data sets and the management of many sponsored programs. His current work focuses on the science of linguistic annotation and the analysis of conversational data, most recently in identifying linguistic features to correlate with clinical diagnostic categories.

Title: Addressing the Language Resource Gap through Alternative Incentives, Workforces and Workflows

Abstract:For most languages, genres and technologies, the absence of Language Resources impedes progress despite several decades of intensive effort from governments and companies around the world. This deficiency even affects languages with worldwide economic and political influence and for most of the world’s 7000 linguistic varieties, the absence is acute. Current approaches cannot hope to meet the resource demand for even a reasonable subset of languages because they seek to document phenomena of great variability using resources that are highly constrained in terms of amount, duration and scope. This paper describes efforts that use non-monetary incentives to elicit greater contributions of linguistic data, metadata and annotation and sketches the adjustments to workforces, workflows and post-processing needed to collect and exploit data so elicited.

The rapid growth of language technology has created a new challenge for many languages of the world today. While for some, this can take the shape of a positive competition among the stake holders, for others it can push them further down in the race towards endangerment and extinction. The LT-LRL Workshop is an attempt to bring together all stake holders, users, developers, researchers, language activists, policy makers on a single platform and discuss how resources, policies, standards could be developed for these languages so that they can develop technologies to enable themselves in the digital age. We will particularly welcome contributions addressing the following issues:

1) LRL: charting the field - what do we know about currently available LTs for LRLs? What is the current status of language technologies and use of LRLs in the digital and social media environments? How to draw a comprehensive and accurate picture and create a road map for future? Who are the actors to be involved? What is the experience of researchers and developers?

2) LRL: Resource development - how are the LRLs dealing with resource crunch, creation and related issues of standards, IDEs and platforms, funding, usability, sharing etc? What are the perceptions and roles of various stake holders including the governments, industry and language communities? What are the additional challenges posed by multilingual societies? What are the language preservation strategies for LRLs in the digital age?

3) LRL : technology development - challenges in the development of specific enabling technologies for LRLs at language, speech and multi-modal levels. How are these technologies used in areas such as communication, education, entertainment, health, administration. governance etc?

Fees: LRL is an integral part of the LTC (with autonomous Program Committee). Fees and payment procedures are the same for general LTC and worshop participants (cover participation in the general LTC program). Notice: the workshop is free for participants registered to the general LTC. Single registration covers only one paper presentation (general LTC or workshops) (cf. the Publication Policy section in case of more than one submitted paper).

Submition:
See the LRL web site: the 5th LRL website.

Reviewing and acceptance: on the ground of blind reviewing

More LRL participation details: cf. also the general program (the access to the program of both the main conference and the workshop (as well as the social program) is the same for all LTC/LRL participants).

Theme and Motivation

PolEval is a SemEval-inspired evaluation campaign for natural language processing tools for Polish. Submitted tools compete against one another within certain tasks selected by organisers, using available data and are evaluated according to pre-established procedures. PolEval 2017-related papers will be presented at a special session during LTC 2017.

Task 1: POS Tagging

There is an ongoing discussion whether the problem of part of speech tagging is already solved, at least for English, by reaching the tagging error rates similar or lower than the human inter-annotator agreement, which is ca. 97%. In the case of languages with rich morphology, such as Polish, there is however no doubt that the accuracies of around 91% delivered by taggers leave much to be desired and more work is needed to proclaim this task as solved. The aim of this proposed task is therefore to stimulate research in potentially new approaches to the problem of POS tagging of Polish, which will allow to close the gap between the tagging accuracy of systems available for English and languages with rich morphology.

Registered systems compete in three settings:

Subtask (A): Morphosyntactic disambiguation and guessing: Given a sequence of segments, each with a set of possible morphosyntactic interpretations, the goal of the task is to select the correct interpretation for each of the segments and provide an interpretation for segments for which only 'ign' interpretation has been given (segments unknown to the morphosyntactic dictionary).
Subtask (B): Lemmatisation: Given a sequence of segments, each with a set of possible morphosyntactic interpretations, the goal of the task is to select the correct lemma for each of the segments and provide a lemma for segments for which only 'ign' interpretation has been given (segments unknown to the morphosyntactic dictionary).
Complete system (C): POS tagging: Given a raw text in Polish, the goal of the task is to segment the text by separating individual flexemes and provide the correct lemma and POS tag for each of the segments.

Task 2: Sentiment analysis

Sentiment analysis is a vital research area, approached at different levels: phrase-level (either in the context of opinion targets/aspects or phrases defined as syntactic sub-trees), sentence-level (related to the task of tweet-level analysis). The aim of this task is to promote research on this topic in the context of the Polish language, provide reference data sets to work and motivation for potentially new methods.

The systems compete in one setting: Given a set of syntactic dependency trees, the goal of the task is to provide the correct sentiment for each sub-tree (phrase). Phrases correspond to sub-trees of dependency parse tree. The annotations assign sentiment values to whole phrases (and in some cases, sentences), regardless of their type.

Presentation of results

All accepted system descriptions, following the LTC 2017-compatible review process (in a special track and with a special deadline set to end of August) will be published in the conference proceedings provided the author registers to the conference under standard LTC conditions. Extended versions of best papers from each main track will be recommended for publication in the post-conference Springer's LNAI volume (subject to additional rounds of reviews).

LTC 2017 will be located in Poznań, Poland. More information soon.

As at the 2nd, 3rd, 4th, 5th, 6th and 7th Language and Technology Conferences (2005, 2007, 2009, 2011, 2013,2015) special awards will be granted to the best student papers. The regular or PhD students (on the date of paper submission) are concerned. Co-authored papers will be considered provided that the students' contributions exceeds 60% and that the main author(s) is (are) student(s)(this fact must be documented by a written declaration signed by all co-authors).

In 2005 the Jury, composed of the Program Committee members participating in the conference, awarded this distinction to: Ronny Melz (University of Leipzig), Hartwig Holzapfel (University of Karlsruhe), Marcin Woliński (IPI PAN, Warsaw) (picture at LTC 2011).
