TABLE OF CONTENTS

Welcome to ECIR 2011, the 33rd European Conference on Information Retrieval which is taking place from the 18th to the 21st April 2011. The conference is organised by Dublin City University in cooperation with the University of Sheffield, and is supported by the Information Retrieval Specialist Group of the British Computer Society (BCS-IRSG) and the Special Interest Group on Information Retrieval (ACM SIGIR). The ECIR 2011 conference (and Industry Day) is being held in the Radisson Blu Royal Hotel, Dublin city centre. The workshops & tutorials take place on the 18th April at the Guinness Storehouse, also in Dublin.

I am delighted to welcome you to Dublin this week and I hope that you have a wonderful stay in Ireland and that you find ECIR 2011 both enjoyable and rewarding. The organisers are very pleased to be able to offer a high quality programme, from the workshops & tutorials, to the papers, posters & demos at the conference, and to the excellent speakers at the Industry day.

There are three social events as part of ECIR 2011: the welcome reception, the posters/demos session and the conference banquet. Where possible, we have endeavoured to include aspects of Irish culture and food in the social experience for ECIR 2011. This includes holding the welcome reception at the Guinness Storehouse, which is the most popular tourist attraction in Ireland, and holding the banquet at the unique venue of The Village at Lyons Demesne in County Kildare (just outside Dublin).

The registration desk will be open during workshops/tutorials at the Guinness Storehouse and throughout the conference at the Radisson Blu. The organisers at the desk will be able to help you with any query that you may have, from conference details, through to important matters such as the best places to eat or drink and to the ordering of taxis. In addition, this delegate’s booklet will provide an overview of ECIR 2011 and information on local activities.

General InformatIon

Presenters Information: The ECIR 2011 oral sessions will take place in GoldSmith’s Halls 1 & 3 in the conference hotel. Both of these rooms are on the ground floor. Industry Day will take place in the Sky Suite on the seventh floor of the conference hotel. The poster and demonstration sessions will take place in two locations, Goldsmiths Hall 2 and the conference centre on the first floor of the conference hotel.

Each of the oral presentation rooms is equipped with a Windows laptop, a projector and a fixed microphone. All presenters should go to their session’s room 15 minutes before their oral session starts, and report to the session chair. A full-length paper will be allocated a 30 minute presentation slot (ideally 25 minutes presentation and 5 minutes questions), while a short-paper will be allocated a 15 minute presentation slot (ideally 12 minutes presentation and 3 minutes questions). It is very important that presenters keep to their time-slots to avoid any cascading delays in the conference schedule.

There is a poster and demonstration session on the evening of the 19th April 2011. It will take place in two locations in the conference hotel. The Goldsmith Hall 2 will host one group of posters and the conference centre on the first floor of the hotel will host the other group of posters and the demonstrations. Please see the Technical Programme for more details.

Meals: Each day will include a 30 minute coffee break during the morning, lunch and a 30 minute coffee break during the afternoon. Lunch will be 90 minutes in duration and will consist of a buffet lunch in the conference hotel. The whole restaurant, bar and open area are available to ECIR attendees for lunch. Attendees are also a short stroll from the Georges Street and the Temple Bar area which provides a wide variety of restaurants if one wishes to eat outside of the hotel. There will be light refreshments provided at the welcome reception and the poster/demo session. For all meal times, please refer to the agenda.

Network: There will be wireless network facilities provided in the conference hotel. Details will be provided in the conference delegate pack.

Power: Ireland uses a UK style power socket. The electrical current is 220 / 240 volts (50 cycles) and the plugs are 3-pin flat. Adapters are therefore required for

3

2-pin appliances. At ECIR we will provide a number of universal power points that will work with most international plugs. These will be located in the Goldsmiths Halls 1 & 3. Conventional Irish power sockets are also located in hotel open areas and seating areas. The reception desk will also keep a limited supply of single plug adaptors which should be returned at the end of the conference day.

Entertainment: Traditional Irish music will be played during both the conference banquet at the Village at Lyons Demesne and during the welcome reception at the Guinness Storehouse.

General Information: For any general information, please inquire at the registration desk, which will be manned for the entire duration of the conference. Do not hesitate to ask any of the registration desk attendees or any volunteer. Volunteers will be easy to identify because they will be wearing orange ECIR 2011 t-shirts.

Climate: Dublin’s climate is mild and very changeable. In April, one can expect an average temperature range from 4°C-13°C (39°-55°F) with a 1/3 chance of rain on each day (averaging 11 wet days in the month of April). Consequently we are providing one disposable raincoat in every delegate's pack.

Tourism: Information and reservation centres can be found at Dublin Airport, Suffolk Street and O’Connell Street. Call into one of their offices and let the experts guide you around Dublin. For more information see visitdublin.com.

Language: English is the spoken language throughout Ireland. Irish (or Gaelic) is the original native language of Ireland and can be heard in daily use in certain regions (e.g. the west coast of Ireland). Place names and signage are usually in both languages. The ECIR welcome address will begin with a welcome statement in Irish.

Currency: The Euro is the only currency that is officially recognised as legal tender in the Republic of Ireland. Each Euro has 100 cent. Most shops (except small ones) accept credit cards. It is useful to keep cash for public transport and smaller items.

Telephone: The international code for Ireland is 00 353. The local area code for Dublin is 01. The numbers for local and national directory enquiries are 11811 or 11850 and for international enquiries 11818 or 11860.

Hospitals and Emergency: In an emergency, call 999 (from a fixed phone) or 112 (from a mobile phone). These numbers will alert the appropriate service - fire, police (Gardaí), lifeboat, coastal, mountain and cave rescue services. For contact points for local healthcare suppliers, please see the last page of this booklet.

Banks & Post Offices: In general, banks open Monday to Friday, 10.00-16.00, with late opening on Thursdays until 17.00. Foreign exchange facilities are available in most banks and in the Dublin Tourism Centre on Suffolk Street. ATM machines will accept all major types of bank cards and credit cards. Most post offices are open Monday to Friday 09.00-17.30 and some open on Saturdays from 09.00-13.00. The General Post Office on O’Connell Street in the city centre is open Monday to Saturday 08.00-20.00.

Business hours: Most businesses are open Monday to Friday 09.00-17.30. Most shops in Dublin city are open from 09.00 until 18.00 Monday-Saturday. Sunday opening is typically from 12.00 until 18.00. Shops stay open late on Thursday evenings in the city centre and late on Friday evenings in the suburbs.

Tipping: In restaurants a customary service charge may be added to a bill. If a service charge is included, tipping is not necessary, unless the service received is exemplary. If a service charge was not included, a normal tip is between 10%-15%. With other services from hairdressers to taxi drivers, it is generally not necessary to tip although staff will always appreciate acknowledgment of service.

Smoking: Dublin was Europe’s first smoke free capital city! Smoking is banned in all enclosed places of work. This includes banks, office blocks, public buildings, pubs, nightclubs, restaurants, cafés. This includes the conference venue and any pub or restaurant that you may eat in while at ECIR 2011. Many pubs and some restaurants have installed or extended existing beer-gardens or patios to cater for those who smoke.

Dublin taxis have no distinctive colour but are easily identified by their official roof signs. Three of the main taxi ranks in the city centre are located on O’Connell Street, College Green and at St. Stephen’s Green. It is also possible to hail taxis on the street and numerous private taxi companies also operate throughout Dublin city and county. Some suggested companies are: Checkers Cabs (+353 1 8343434), Co-Op Taxis (+353 1 6766666), Express Taxis (+353 1 8553333) & VIP/ACE Taxis (+353 1 4783333). It is advisable to allow up to 60 minutes to travel by taxi from the conference hotel to the airport during rush hour (16:00-19:00). At other times, it will take between 20-30 minutes.

Dublin Bus operates the city’s bus routes. Depending on the location, buses run from 06.30-23.30. Dublin Bus operates an exact fare policy so it is advisable to have correct change ready when boarding the bus. Fares are dependent on age and destination. For details on all routes, timetables and special value tickets available, enquire at any Dublin Tourism Office or directly at Dublin Bus, 59 Upper O’Connell Street, Dublin 1 or www.dublinbus.ie.

Bus Éireann is Ireland’s national bus company. It provides bus services throughout the country with the exception of Dublin City. The majority of buses depart Dublin from the central bus station (Busáras) on Store Street in the city centre. For more information, timetables and services see www.buseireann.ie.

Train: Iarnród Éireann (Irish Rail) operates the nationwide rail network. The DART (Dublin Area Rapid Transit) is Dublin’s main train service and stretches the full length of Dublin Bay, from Malahide in North County Dublin to Greystones in County Wicklow. Suburban Rail covers commuter routes to and from Dublin and InterCity trains service major cities and towns around the country. Details on all routes, timetables and special value tickets are available at www.irishrail.ie.

The Dublin tram system is called the LUAS. It is a state of the art light rail transit system with high capacity, high frequency and high speed services. The Luas runs on two tramlines: - The Green Line – connecting Sandyford to St. Stephen’s Green – journey time approximately 22 minutes. – The Red Line – connecting Tallaght to Connolly train station – journey time approximately 46 minutes. Details on routes, timetables and tickets are available at www.luas.ie.

Welcome reception:

The welcome reception for ECIR 2011 will take place on the evening of the 18th April 2011 at the Guinness Storehouse, the same venue at which workshops/tutorials will have been held earlier that day. The seventh floor Gravity bar will be the venue which provides a unique 360-degree view over the city of Dublin. Prior to this, the lower levels of the Guinness Storehouse will remain open especially for ECIR 2011 welcome reception attendees to explore the history of Guinness. Attendees can arrive from 18:30, with the gravity bar opening at 19:30. Traditional Irish music will be played during this event.

The Storehouse is an industrial building, originally built in 1904 in the style of the Chicago School of Architecture, with massive steel beams providing the support for the entire structure of the building. The Storehouse housed the fermentation of Guinness beer until 1988. In November 2000, the Storehouse opened its doors to the public and has quickly become Ireland’s number one tourist attraction.

banquet:

The conference banquet will take place at The Village at Lyons Demesne in County Kildare (6.541566W, 53.306316N). The Village is beautifully situated alongside the Grand Canal and is a rare and amazing treasure of architectural features, master craftsmanship and decorative detailing which was lovingly restored in 2006. The village derives its name from an ancient town and castle, which were both destroyed in the war of 1641. The Village incorporates a restaurant, wedding venue, shops and boutique accommodation. The conference banquet will take place at the two-level Mill restaurant, which overlooks cascading waters. The room’s panelled walls are complimented by rich tapestries, offset by a soft and relaxing palette of neutral shades, while the dramatic 17th century fireplace and soothing sounds from the waterfall add to the uniqueness of the room.

The proposed banquet schedule is:

• 18:15-18:30 - Buses depart from the Radisson Blu Hotel• 19:00-19:15 - Arrive at Lyons estate for pre-dinner reception• 19:45 - Conference Banquet until 22:30• 20:00 - Harpist set begins• 20:30-23:00 - Buses depart for the Radisson Blu Hotel and the
