Why CICLing?

This conference is the eighth CICLing event. The past CICLing conferences have been very successful, according to the comments of the participants: Fantastic conference! (Martin Kay, 2004), Everything was just great! Super-hyper-ultra-well done! (Igor Mel'cuk, 2000). We consider the following factors to define our identity:

   Excellent keynote speakers. We invite the most prominent scientists of the field to give keynote talks which, unlike at many other confs, are published in extenso in the Proceedings. They also organize an additional tutorial or discussion, and usually even participate in the excursions, where you can speak with them in an informal environment. [Past participants' opinions]

   General interest. The conf covers nearly all topics related to computational linguistics. This makes it attractive for people from different areas and leads to vivid and interesting discussions and exchange of opinions.

   Informal interaction. It is intended for a rather small group of professionals. This allows for informal and friendly atmosphere, more resembling a friendly party than an official event. At CICLing you can pass hours speaking with your favorite famous scientists who you scarcely could greet in the crowd at large conferences.

   Excellent excursions. Mexico is a wonderful country rich in culture, history, and nature. The conference is intended for people feeling themselves young in their souls, adventurous explorers in both science and life. Our cultural program brings the participants to unique marvels of history and nature hidden from the ordinary tourists.

   Relief from frosts. In the middle of February frosts, the participants from Northern countries can enjoy bright warm sun under the shadow of palms.

The conf is organized by the Center for Computer Research (CIC) of the National Polytechnic Institute (IPN), Mexico. The IPN is one of the largest universities in the world, with over 120,000 students. The CIC is a relatively new school devoted to the cutting edge research in all areas of science related to computers, both in software and hardware. The conf is organized by the Natural Language Processing laboratory of CIC (you can find some our publications at

Areas of interest

In general, we are interested in whatever helps, will help eventually, or might help computers meaningfully process language data.

The conference is intended to the exchange of opinions between the scientists working in different areas of the growing field of computational linguistics and intelligent text processing. Our idea is to get a general view of the state of art in computational linguistics and its applications.

Areas of interest include, but are not limited to, the following topics, as long as the topic is presented in computer-related or formal description aspects:

Computational linguistics research:

   Computational linguistic theories and formalisms

   Representation of linguistic knowledge




   Discourse models

   Ambiguity resolution

   Word Sense Disambiguation

   Anaphora resolution

   Text generation

   Machine translation

   Statistical methods in computational linguistics

   Lexical resources

Intelligent text processing and applications:

   Document classification and search

   Information retrieval

   Information extraction

   Text mining

   Automatic summarization

   Spell checking

   Natural language interfaces

Naturally, we welcome the works on processing any language, not necessarily English, though major languages are of more general interest. Note: when describing phenomena of languages other than English, please be sure to make your discussion understandable for people not familiar with this language.

You can have a look at the past CICLing-2006, 2005, 2004, 2003, 2002, 2001, 2000 tables of contents to get an idea of our interests. If you are not sure whether your particular topic is of interest, please do not hesitate to ask us.

Keynote speakers

  Gregory Grefenstette

Professor of the Laboratoire d'ingénerie de la connaissance multimédia multilingue, France.

Topic of the special event: Is NLP good for anything?.

  Kathleen McKeown

Professor of Computer Science Department at Columbia University, New York, USA.

Topic of the special event: Evaluation: When does it help and when does it hurt?

  Raymond Mooney

Professor of Computer Sciences, University of Texas at Austin, USA.

Topic: To be announced.

more to be announced

Traditionally, our keynote speakers give a formal talk, which is also published in extenso in the Proceedings, and also organize a "special event" (a discussion, tutorial, experiment, or something just interesting). Such events, as well as publication of the keynote talks in the Proceedings, are distinguishing features of CICLing.

Notification of acceptance

November 19

Camera-ready & early registration (see here) deadline

December 8


February 18 to 24

We cannot guarantee processing of any paper that does not arrive by the corresponding deadline. However, you may contact us if you really cannot submit your paper in time, and we will see what can be done.


Authors of accepted papers: By submitting a paper, at least one author thereby promises, in case of acceptance of the paper, to attend the conf in person to present the paper and to pay the corresponding registration fee.

We expect to provide a way to pay by credit card via Internet. The payment instructions will be announced here later.

Registration fee:




Local students


US$ 340

US$ 270

free entrance

On site

US$ 390

US$ 320

On reduced registration fee: A very limited number of reduced registrations may be available. To apply, please contact us and thoroughly justify your application. Eligible for reduced registration can be people from underdeveloped countries in case if their institutions have real difficulties paying the full fee (included: Latin America, Eastern Europe; not included: North America, Western Europe, Japan, South Korea). Authors must apply for reduced registration (clearly indicating the discount amount) before submission of their paper. No new applications will be considered for already reviewed papers. Notes: (1) Though all papers are judged by strictly academic criteria, (only) for borderline cases and (only) between papers of comparable quality we may give preference to papers with fully paid fee. (2) Though we will do our best for this not to happen, we cannot guarantee providing the conf material (including the Proceedings) and the conf lunch tickets to participants with reduced fee. Also, in case of lack of seats in the excursion bus we will give preference to fully registered participants.

Submission guidelines

See a link to the submission web system at the end of this section. However, please read first the format guidelines.


All accepted papers will be published in a Proceedings volume edited by Springer-Verlag in its Lecture Notes in Computer Science series.

The papers should not exceed 12 pages. A small additional fee will be charged for additional pages exceeding this limit. Please contact us if you exceed the limit by more than 2 pages. The additional fee is charged for the pages exceeding the page limit in either the version submitted for review or in the camera-ready version, whichever is greater. This means that you should not shorten the camera-ready version in comparison with the version submitted for review, unless the reviewer required this; in any case such shortening would not reduce the additional fee.

Note: Traditionally, there has been the modality of short papers. Since this year, according to the instructions that we received from our publisher, Springer, we only offer the modality of full papers. We apologize for inconvenience. Poster session papers will be published in another journal.


Please provide your paper in the form in which it should appear in the book (but without page numbers, running heads, and copyright note). However, since the review process is double blind, please do not indicate the author names or any information that may disclose the authors' identity (obviously, in the camera-ready version you should indicate the names).

Please strictly follow the format guidelines of Springer LNSC series (you can get the style files here). We cannot guarantee publication of any paper that does not follow these guidelines. Please do not hesitate to ask any questions.

The following are frequent formatting problems:

1.     Word users: Do not underline email addresses or URLs, and do not write them in blue font. See also below the notes on bugs in the Word template.

2.     All figures, tables, formulas, etc. must be within margins. We will not be able to include papers that do not meet this requirement.

3.     All pages must be free of page numbers and running heads.

4.     Please do not leave unused space on the pages. Try moving your figures if they cause unused space. Avoid if possible the last page being filled less than to 1/3.

5.     No section title should be the last line on the page. Avoid widow and orphan lines.

6.     All section titles must be First Letter Capitalized.

7.     Figure captions must be below the figure; table captions must be above the table (especially important for TeX users). Both figures and tables should be centered.

8.     Do not use colors in figures: they will not be visible in paper book. Especially in Excel drawings, a blue and a red line will look the same, and a yellow line will not be visible at all. In Excel drawings, eliminate the outer frame and make the background white (not grey), see below.

9.    For homogenous look of the book, please format the tables, whenever it does not cause difficulties in understanding the table, with only three thin horizontal lines:


   Collection   R   P   F       
  Reuters  0.6   0.8   0.7   
  CACM   0.7   0.7   0.7   
  BNC  0.8   0.6   0.7   
  Penn  0.9   0.5   0.8

  ::: |||| ///   ::: |||| ///   ::: ||||    
  ::: |||| \\\   ::: |||| \\\   ::: ||||    
    ::: |||| ///   ::: |||| ///   ::: |||| ///    

9.     If the title of your paper does not fit in one line, please divide it into logical parts (with Shift-Enter in Word, or \\ in TeX):


A Method of Calculation of Semantic Word




A Method of Calculation
of Semantic Word Distance

Note for Word users: the template file currently provided by Springer has the following bugs that you must correct in the text of your paper (if they affect you) in order for it to be published:

1.      All centered paragraphs (title, author, address, email, equation, etc.) and some other special paragraphs (table and figure captions) incorrectly have 0.4cm first line indentation, set it to 0 (not indented). This can be done through the menu by changing Format | Paragraph | Indenting | Special to none or (for expert users) by modifying the corresponding style.

2.      Bulleted lists seem to have a problem with the bullet character. You can choose another bullet character through the menu Format | Numbering and lists | Bulleted lists | Personalize or (only for expert users!) by modifying the corresponding style.

3.      Table captions should be centered; this can be changed through the menu by setting Format | Paragraph | Alignment to centered. Also, table caption style has German language, you might want to set it to English through Tools | Language | Define Language.

Submission procedure

We accept only electronic submissions, which should be properly formatted. See a note on reduced registration fee. All papers are to be registered and uploaded through the submission page.

Submission is done in two steps. Before the abstract registration deadline, you should register your paper. You only need a tentative abstract at this stage (the real abstract can be improved later). Then, before the full text uploading deadline, you should upload a PDF file with the complete and finished paper. Only the papers for which the abstract has been registered in time can be uploaded at this point. No new papers can be registered after the paper registration deadline has been expired.

Poster & Demo session

Poster session

The papers accepted for the poster/demo session will be published a special issue of the journal Research in Computing Science, ISSN 1870-4069. The size of the papers is the same as for the oral session, see here. The modality of short papers will not be available. If you want your paper to be considered for the journal Research in Computing Science in case if it is not accepted for the Springer LNCS volume, please tick the corresponding [X] checkbox when registering your paper.

For posters, you will be given approximately 2 square meters of vertical surface to attach your material. If you have some special requirements, please let us know. Please put your photo in a visible place on your poster (or main page of your demo) for people to easier locate you while you are looking at others' posters and demos. The following common-sense advice improves your presentation:

For a poster

   Arrange individual pages vertically, in columns, from top to bottom. Horizontal arrangement of pages makes the readers to zigzag when reading your material. Please number pages clearly to indicate the direction of reading.

   Use large font, at least 20 pt, and much larger for headings. Note that you probably will explain your poster to several or many people at the same time.

   Have detailed and additional material handy, though do not attach it together with your main material. It is a good idea to prepare some sufficient number of handouts.

For a demo

   Have a working program, not a PowerPoint presentation (which should constitute your poster instead).

   Prepare some plan of your demonstration, including some examples tested in advance.

   Prepare all necessary input files in advance, even if small. On the other hand, give the users a chance to test their own examples and play with your program’s options.

   If possible, have handy some floppies or CDs with your program and documentation to give out to attendees. Clearly indicate your name, email on these disks. Indicate a webpage where more info can be found.

Presentation: All posters and demos will be presented during the Poster/Demo session (combined with the Welcome party) on the first working day of the conference. Later, they can also be demonstrated during breaks to interested attendees.


During the poster/demo session and breaks, all participants will have a chance to demonstrate the material related to their talks or posters. However, the number of PCs for demonstration will be limited; please contact us in advance if you need one. You are encouraged to bring your laptop with your demo. Demo platforms provided by the organizers: PC with Windows 2000/ME/XP (by our choice, no guarantee of some specific version), CD and floppy drives; no significant space on the disk is guaranteed. If you need a specific version of Windows or some another OS or platform please contact the Committee in advance, as well as if you need some significant disk space, Internet access, or any special hardware or software.

Tentative general schedule


See submission deadlines in the section Important Dates.

There will be three and half working days and three and half days of excursions. You can arrive on Monday and leave on Friday if you wish; you will lose two excursions.

The general schedule is as follows:

  Sunday, Wednesday, Saturday: excursions.

  Monday morning, Tuesday, Thursday: talks.

  Monday evening: welcome party, posters, and demos.

Note for the participants of past CICLing events held in Mexico: we plan to repeat nearly the same excursions; I apologize for inconvenience. I advise you two options: either to stay just from Monday to Friday or to arrive earlier and visit some very interesting places to which we cannot organize an excursion, for example: Tula (2 hours by bus), El Tajin (7 hours); or: arrive to Cancun and visit Chichen-Iza, Uxmal, Palenque, La Venta-Villahermosa traveling to Mexico City (2 nights in bus, 3 days of sightseeing). There are many other good options if you are adventurous enough and can rent a car or pass nights in the buses. Please ask me for more info.

Accepted papers and Program

The list of accepted papers and the program to be announced.

Cultural Program


One of the most exciting things at the conference are excursions to the ancient Indian pyramids and visiting a unique natural phenomenon, the Monarch Butterfly wintering site where you can see millions of beautiful butterflies in the trees and in the air around you. In common opinion of the participants of the previous events the excursions were excellent; you can see their own photos: CICLing-2000, 2001, 2002, 2003, 2005, 2006, as well as Ted’s site.

Warning: the excursion to the butterflies site is very long and tiresome, especially for elder people. We really think it is very worth the trouble, but you decide. Note that population of the butterflies changes from year to year, so we cannot guarantee any particular number (or presence) of the butterflies.

Note: Please bring with your (valid) Student / Professor / Teacher ID, and have it with you at all excursions. This will help us to reduce our expenses, since the entrance to some sites with such an ID is cheaper.

Here is the list of excursions:

   Excursion to Teotihuacan: ancient Indian pyramids, 1 hour drive, much (but slow) walking.

   Excursion to Angangueo: Monarch Butterfly wintering site, 4 hours drive, hard walking up the hill.

   Informal short walk by the City Center ("Zocalo").

   Excursion to the Anthropological Museum.

   Excursion to Xochicalco ancient pyramids, Cacahuamilpa cave and colonial city Taxco, 2+1+1 hours drive, much (but slow) walking.

Note for past CICLing participants: I do understand that repeating the same excursions is a bad idea. On the other hand, these are the best ones, and significantly changing the list would not be fair to the new participants. If you have any specific idea on what you would like to visit, please let us know and we will try to arrange for this.

We are open to any ideas on what other excursions would be interested. Please let us know your ideas.

Welcome party

The reception party will be combined with the Poster and Demo section. We will have some snack, maybe some wine. (No music, no heavy food, even no tables, sorry. We consider official banquets waste of your valuable time.) You will enjoy the informal atmosphere to speak with each other and with the presenters of the posters and demos. You will also have a chance to show and discuss your own programs (for this, please let us know your software and hardware requirements).


We suggest that it is convenient for the participants to stay in the same hotel, to facilitate informal interaction. Usually our participants form ad-hoc informal companies in the hotel reception to go to some restaurant, walking tours, etc. We will do our best to provide free transportation from the recommended hotel to the conf place. Also, we have discounted rates for the participants of the conference.

 NEW  The official hotel of the conference is **** El Ejecutivo: it is affordable, nice, and located in the central district. Address: Av. Viena # 8, Colonia Juarez, Mexico DF, 06600. Tel. +52 (55) 5566-6422, 5566-6565, fax +52 (55) 5705-5476, booking +52 (55) 5535-5088. Here you also can see a booklet with some info and a local map, and here the other side of the booklet.

You do not need to reserve your room; we will do it for you. Please send us a message (at the hotel@ address) well in advance indicating:

   your name,

   dates: check-in day, check-out day,

   type of the room (single, double, triple, quadruple),

   number of persons,

   whether you prefer to share the room with other persons. In this case, what type of room (double or triple), and your gender. We will try to find a roommate for you, for your whole stay or for a part of your stay (while you will pay the whole price for the days for which we could not find you a roommate). Note that there is no guarantee: your request for a shared room does not guarantee that we will be able to fulfill it, and you will pay the whole price for the days when you owned the whole room. If you prefer to share a room with a specific person, please contact that person instead and send us one request for a double room (indicating two names), not two separate requests, to avoid confusion.

   any other indications.
