Dear Colleagues,

You are kindly invited to participate in the 3rd Language and Technology Conference (L&TC'07), organized by the Faculty of Mathematics and Computer Science of Adam Mickiewicz University, Poznan, Poland in cooperation with the Adam Mickiewicz University Foundation.

At the beginning of the 7th Framework Program, recently launched by the European Commission, Human Language Technologies continue to be a challenge for computer science, linguistics and related fields as these technologies become an ever more essential element of our everyday technological environment. Since Ajdukiewicz, Tarski, Turing and Chomsky (i.e. since the very beginning of the Computer Age) these fields have influenced and stimulated each other. Technological, social and cultural globalization has 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 we invite you to join us at L&TC'07 in October, 2007.

Zygmunt Vetulani
L&TC'07 Chair
vetulani@amu.edu.pl

The conference program will include the following topics:

• electronic language resources and tools
• formalisation of natural languages
• parsing and other forms of NL processing
• computer modelling of language competence
• NL user modelling
• NL understanding by computers
• knowledge representation
• WordNet technologies, ontologies (cf. L&TC WordNet Special Track)
• man-machine NL interfaces
• Logic Programming in Natural Language Processing
• corpus linguistics
• speech processing
• NL applications in robotics
• text-based information retrieval and extraction, question answering
• question answering
• tools and methodologies for developing multilingual systems
• translation enhancement tools
• methodological issues in HLT
• prototype presentations
• language-specific computational challenges for HLTs (especially for languages other than English)
• HLT standards
• HLT support for foreign language teaching
• communicative intelligence
• legal problems connected with HLTs (problems and challenges)
• contribution of HLTs to the homeland security problems (application and legal aspects), cf. L&TC Homeland Security Workshop,
• vision papers in the field of HLT
• HLT related policies

You will have noted that we intend to continue traditional HLT interest areas (cf. L&TC'05 topics). You may also have observed that we have included a new dimension at the frontier between HLTs and the Homeland Security field. We invite authors working in this domain to contribute either on theoretical issues (e.g. legal aspects of development and application of HLTs) or technical developments (applications, software, language infrastructure and tools), see L&TC Homeland Security Workshop. Political and mature vision papers in this field are also welcome.

This list is by no means closed and we are open to further proposals. The Program Committee is also open to suggestions concerning accompanying events (workshops, exhibits, panels, etc). Suggestions, ideas and observations may be addressed directly to the L&TC Chair by email (vetulani@amu.edu.pl).

The 3rd Language & Technology Conference will be held in the Poznań International Fair Conference Center (Głogowska 14), pavilion 14B (see the International Fair map).

Conference opening ceremony will take place in Rotunda (pavilion 11 of the Poznań International Fair Conference Center).

Conference participants will have to pass two registration desks. First they will be greeted at the desk located in the East Gate hall of Poznań International Fair. The proper registration desk will be set in Rotunda (pavilion 11 of the Poznań International Fair Conference Center), where the conference opening ceremony will take place. This desk will later move to pavilion 14B, where the technical session will be held.

Ryszard Grobelny, Mayor of Poznań, will receive conference attendants in City Hall in Old Market Square (Stary Rynek).

The conference banquet will take place in Sala Lustrzana (the Mirror Hall) of Adam Mickiewicz University's Collegium Minus (Wieniawskiego 1).

LTC'07 special award for best student paper was presented to Darja Fišer by the Jury composed of the Program Committee members present at the conference.

Darja Fišer graduated from the Department of Translation Studies at the Faculty of Arts, University of Ljubljana, Slovenia in 2004 with a thesis on translation memory systems that received the faculty award for best thesis. As a junior researcher at the same department she is working towards her PhD in computational lexical semantics, more specifically on the development of Slovene wordnet. She also participates in several national projects in the field of human language technologies, and teaches courses on translation technologies and lexical semantics. Apart from working she likes travelling, hiking, photography and reading.

Ronny Melz (University of Leipzig),
Hartwig Holzapfel (University of Karlsruhe),
Marcin Woliński (IPI PAN, Warsaw).

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 http://www.mpk.poznan.pl/wg_linii.html. (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 http://www.info.poznan.pl/Map/MapControl.html?Id=0. (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 1.30, A 30-minute ticket costs PLN 2.60 and a 60-minute ticket is PLN 3.90. 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.

The currency of Poland is Polish złoty (PLN). Złoty is subdivided into 100 groszy (singular: grosz). As for September 26, 2007, the euro/złoty exchange rate is 3.78, the dollar/złoty exchange rate is 2.68.

If you are arriving by plane, you can get to the city centre by bus or by taxi. Two bus lines run from the Poznań-Ławica Airport to the city centre: 78 and 59 (see information on public transport). Bus 78 departs from the airport grounds and bus 59 departs from the opposite side of Bukowska street. The bus needs approximately 20 minutes to reach the city centre. Poznań International Fair building complex is located near the "Bałtyk" stop. The taxi rank is located in front of the airport's arrival hall. You may also call a taxi (in Polish or English) by dialing the number 9622 (no prefixes). Depending on the traffic, you will pay PLN 25-40 to get to the city centre.

If you do not feel like walking from the Conference Center to the City Hall, you can take tram no 5 (see information on public transport) in front of the Conference Center and get off at the Wrocławska street stop.

During lunch hours a restaurant will be open in pavilion 15 (see the International Fair map).
