New tool for the detection of discourse markers in Spanish

For a long time we were in the need for some tool that could detect and classify discourse markers (DMs) in Spanish according to the taxonomy of Martín Zorraquino & Portolés (1999), as this taxonomy is the one we use with our students of Text Grammars. We collected a large sample of DMs both manually and automatically, but the collection we now publish has been manually curated. It is published here in its entirety (if you spot some mistake please let us know).
In this demo you can paste a text in Spanish and the program will detect and classify DMs according to said taxonomy.

The documentation is still pending.

We presented lots of papers at Wopatec 2020

Our team presented various communications at the Fifth Edition of Wopatec, which was this time co-organized with the Third International Congress of Computational and Corpus Linguistics, held in October 21-23, 2020 and hosted by Universidad de Antioquia in Colombia. Members of our team who presented their research were Javier Obreque, Ana Castro, Valentina Ravest, Benjamín López, Nicolás Acosta and Rogelio Nazar. Six presentations in total... yeah we sort of invaded the program.

New web demo for modality detection in Spanish

Yeah, we know. We are crazy. We should focus on one thing at a time and try to make a piece of software that really works. Instead of that, we keep biting off more than we can chew. We can't help it! It's in our nature. We are now launching a new web demo based on modality detection in Spanish. It takes a text as input and it detects and classifies instances of modality. It's pretty cool.
Come on, give it a try:
And, you guessed it: the documentation is still pending.
Update: [October 23, 2020]: we added some documentation.

+ GeNom: a program to detect the gender of proper nouns

+ HAT: a project for the treatment of polysemy in lexical taxonomies

+ Jaguar: a tool for statistic corpus analysis

+ Kind: a taxonomy induction algorithm

+ Kwico: a concordancer for big corpora

Upcoming Events

October 21-22, 2020: Wopatec is back! The 5th Workshop on Natural Language Processing will take place in Antioquía, Colombia, in conjunction with the 3rd International Congress of Computational and Corpus Linguistics. For the first time, the event will be held completely online.

November 30, 2020: Rogelio Nazar will be gest editor of the special issue on Computational Linguistics of the journal Anales de lingüística, founded by the great Catalan linguist Joan Corominas in 1941, at Universidad Nacional de Cuyo, Argentina.
If you would like to have your paper published in this issue, send it by email to rogelio dot nazar at pucv dot cl before the deadline indicated in the heading.
Here is the call for papers (at the moment only available in Spanish).
And here the instructions for authors.

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.

Tell us which are your needs and we will show you what we can do about it.
