Dear Colleagues,

The 4th Language and Technology Conference (LTC'09), a meeting organized by the Faculty of Mathematics and Computer Science of Adam Mickiewicz University, Poznań, Poland in cooperation with the Adam Mickiewicz University Foundation (co-organizer), will take place on November 6-8, 2009.

Human Language Technologies (HLT) continue to be a challenge for computer science, linguistics and related fields as these areas become an ever more essential element of our everyday technological environment. Since the very beginning of the Computer and Information Age these fields have influenced and stimulated each other. The European Union strongly supports HLT under the 7th Framework Program. These efforts as well as technological, social and cultural globalization have created a favorable climate for the intensive exchange of novel ideas, concepts and solutions across initially distant disciplines. We aim at further contributing to this exchange and invite you to join us at LTC in November 6-8, 2009 as well as at the satellite FlaReNet workshop (November 6) co-located with the LTC'09.

This event is listed at the Computer Science Event List,

JOINT LTC-FLaReNet SATELLITE WORKSHOP: Getting Less-Resourced Languages on-Board!

Name: Getting Less-Resourced Languages on-Board!

(New) Date: 6.11.2009, half-day (afternoon) + banquet

Theme: Language Technologies (LT) provide an essential support to the challenge of Multilingualism. In order to develop them, it is necessary to have access to Language Resources (LR) and to assess LT performances. To this regard, the situation is very different across the different languages. Little or sparse data exist for languages in countries or regions where limited efforts have been devoted to such issues in the past, also known as Less-Resourced Languages (LRL). The workshop aims at reporting the needs, at presenting achievements and at proposing solutions for the future, both in terms of LR and of LT evaluation, especially in the European, Euro-Mediterranean and regional frameworks. This will allow to identity the factors that have an impact on a potential and shared roadmap towards supplying LR and LT for all languages.


  • Experience in the production, validation and distribution of LR for less-resourced languages
  • Experience in the evaluation of LT for less-resourced languages
  • Infrastructures for making available LR and LT in less-resourced languages
  • Alternative approaches (comparable corpora, pivot languages, language clustering…)
  • To be completed...

Co-Chairs: Joseph Mariani (LIMSI-CNRS & IMMI-CNRS), Khalid Choukri(ELRA & ELDA), Zygmunt Vetulani (Adam Mickiewicz University, Poznan)

CLARIN-FLaReNet LTC Panel Debate: "How to make standards attractive = how to make attractive standards?"

Key issue: "How to make standards attractive = how to make attractive standards?"

Organisers: CLARIN, FLaReNet

Moderator: Steven Krauwer (CLARIN/ELSNET/UiL OTS)

Inved panelists : to be confirmed

Objectives: A precondition for standards to be attractive seems meeting real needs of the community of users. Identification of needs is therefore essential and improving methodologies which would permit doing it correctly is an important challenge. This is also an urgent task regarding the globalisation pressure and the risk of growing technological gap between the so called "Less-resourced languages" and technologically leading ones. The panel is intended to be a contribution to face this challenge.

Planned date: 7.11.2009, afternoon

Special Track on Information Technologies in application to the Public Security Research

Objectives:The aim of the ITPS Special Track is an overview of the results obtain within three years research-and-development projects of PPBW, as well as confrontation of the results obtain so far with the initial expectations and the newly manifested needs. This Special Track aims at detection of new application areas of Language Technologies in the field of Public Security.

Key words: Homeland security, Human language technologies, Systems with natural language competence, Language engineering resources for the security domain, Speech and text processing, Multilingual aspects, Legal aspects of human language technologies of security domain

Organisers: PPBW - Polish Platform for Homeland Security

Chairs: Dr. Zbigniew Rau (PPBW), Prof. dr. Emil W. Pływaczewski (Univ. Białystok)

Secretary: Rashel Talukder(PPBW)

Contributors : invited representatives of the PPBW projects and external presenters

Participants : the ITPS is an integral part of the LTC and is open to all LTC participants

Submissions : the external presenters are supposed to follow the same procedure as for the LTC, additionally, they are requested to send a security copy to Rashel Talukder and Zygmunt Vetulani by September 6 (with "LTC-ITPS Workshop" in the "subject" field); in particular, both invited and external presenters should submit papers using the EasyChair system (accessible via

Publications : as for LTC

Even though we did our best to make sure all conference locations are within walking distance, conference guests may wish to use the public transport. Fortunately, Poznań boasts a vast public transport network.

The timetable (by tram or bus line) can be viewed at (After choosing the line, one has to choose the proper bus or tram stop in the right direction.)

An interactive transportation map is available at (You type the street name in the text box to see the chosen part of town and display bus and tram lines by selecting A for buses and T for trams from the left upper corner menu.)

A 10-minute adult ticket costs PLN 2.00, A 30-minute ticket costs PLN 3.60 and a 60-minute ticket is PLN 5.80. They are valid in both trams and buses. You have to validate the ticket in a special machine inside the vehicle. Within the time frame you can change lines. Normal tickets are valid also for the night buses and trams.

You can buy tickets in one of the newspaper stands near bus stops.


Electronic tickets Electronic tickets allowing conference participants to enter the Poznań International Fair area will be available in the Entrance Hall (Hol Wschodni). The tickets are valid for the three days of the conference. Conference participants should carry the tickets with them at all times. It is not possible to enter the Fair area without the ticket.

Wi-Fi Free wireless Internet is available in pavilion 14B (where the conference takes place). Please choose the MPT network (unprotected).

Taxi You can call a taxi free from the reception desk.

Restaurants The following restaurants are in near proximity of pavilion 14B (where the conference takes place):

  • an Asian restaurant (Śniadeckich Street)

Tram trip On November 7 (Saturday) at 16:55 we meet by the reception desk to go on a guided tram tour around Poznań. Two historical trams will take conference participants from Dworzec Zachodni (Western Train Station) to Wrocławska Street. From there we will take a short walk to the City Hall, where we will meet the President of Poznań. The trams will leave from the stop by Dworzec Zachodni at 17:20. Because we will use the public tram network, it is impossible to leave with any delay!
