Six of our students presented their theses

Extremely talented young people working with us... This Friday, six of our students presented their theses, after a year's hard work. Pedro Bolbarán, Camila Pérez, Bahony Saavedra, Gabriela Cacciuttolo, Héctor Ramos and Javiera Silva are seen smiling at the camera after the defense, surrounding a very proud adviser. They were supposed to write undergraduate theses, but their work looks more like PhD theses! The manuscripts will soon be available online at the library of PUCV.cl

We presented new paper at Euralex 2022

Irene Renau presented the paper ``Towards a multilingual dictionary of discourse markers: automatic extraction of units from parallel corpus'', at the EURALEX 2022 Congress, held in Mannheim, Germany. The talk described our project Dismark, the multilingual database of discourse markers, which is now in the process of becoming a dictionary. The paper is available here.

We just presented a paper at Terminology in the 21st century

Today, at 16:45 Central European Time (that is, 10:45 Chilean time) Rogelio Nazar and David Lindemann presented the talk Terminology extraction using co-occurrence patterns as predictors of semantic relevance in the workshop on Terminology in the 21st century: many faces, many places (Term 21), co-located with LREC 2022 in Marseille, France. The paper is available here. The program of the workshop is available here, and the full Proceedings are available as well.

We delivered an online presentation at DISROM 7

Today, Irene Renau, Rogelio Nazar and Hernán Robledo presented the talk Automatic extraction of discourse markers from parallel corpus at the Discourse Markers in Romance Languages Conference (DISROM 7). The conference is taking place these days (16-18 June 2022) in Craiova, Romania, but it's also broadcast online. There are many other interesting presentations that you can follow: http://disrom2022.wordpress.com

We have a new toy: Clusterre

This script is intended as a friendly interface to R's clustering function. It will create dendrograms from several (up to nine) lists of items, as well as the data matrix if you want to use it for something else. There must be only one item per line. Any other information will be ignored, as these are treated as binary values only. The result is the matrix and the dendrogram. Happy clustering! What's new? You can now name the objects using the first element in each list as header. Just remember to click on the checkbox if those are your intentions. http://www.tecling.com/clusterre

MANDINGA is back!

Mandinga, our dear old word sense induction algorithm, is now back online, after many years forgotten. Given an input word, it tells if said unit is polysemous and, if so, it produces a list of the possible senses. Of course, it does not use any lexicographic resource. It does all using only corpora and graph-based co-occurrence algorithms: http://www.tecling.com/mandinga Update (May 9, 2022): At this moment the system is available in Spanish, English and French.

NEOPTER: identification of neologisms in a list of Spanish words

This is what happens when we have a lot of paperwork to do: we divert efforts to the creation of new demos. Now we have Neopter, a little script that takes a list of Spanish words and identifies those that had not been used prior to 2012. To enjoy (with moderation): http://www.tecling.com/neopter

GEOMOT: a script to find the distribution of Spanish words per country

We have a new product on display today. Geomot is a script that will accept one or more Spanish words and will tell in which countries they are most frequently used. We find it useful for different types of Spanish lexicographic projects. Next step will be to do the same in Arabic, as this language shares with Spanish the phenomenon of wide geographical lexical variation. http://www.tecling.com/geomot

MORFOL: a new Spanish morphological analyzer

Morfol is a brand new morphological analyzer for Spanish that we are using for the categorization of terms and neologisms. It accepts a list of terms/words/neologisms (one per line) and then proceeds to classify them. It will produce the grammatical category, grammatical genre and also, by trying to identify prefixes and suffixes, the internal morphological structure. Give it a try and tell us what you think about it: http://www.tecling.com/morfol

We have implemented different types of applications and most of them can be tested online. Take a look.

Solutions for text processing

It is critical for organizations to have the ability to process information automatically, and very often that information is contained in documents to be read by humans rather than machines. We have different methods for text processing depending on the goal.

We can be helpful teaching people how to automatize their text processing routines. We can batch-process thousands of documents to extract information from them or to derive different types of statistics. We can also change these document, or generate databases or email correspondence based on information extracted from them. Anything that involves intelligent management of information can benefit from different degrees of automatization, and by doing that we can free time, effort and resources.
