Rogelio Nazar will offer a course at JELing


From Wednesday November 13 to Friday 15, 2019, Rogelio Nazar will be presenting a course titled "Introduction to Computational Linguistics" at JELing, which will take place at Univerdad Nacional de Cuyo, Mendoza, Argentina. The course is a gentle introduction to the state of the art of this area of ​​linguistics and he will explain the basics of different computational tools for natural language processing, from concordancers, to regular expressions, Perl and R programming languages and some basic Linux commands.

We are presenting Verbario at PhrasaLex


Irene Renau and Rogelio Nazar will present the talk: "Verbario: A database of Spanish verbs as source for pedagogical lexicography". The presentation is about Verbario, a database of Spanish verbs built with the Corpus Pattern Analysis (CPA) technique. The database from manual analysis of Spanish verb patterns has been updated with new examples extracted from corpora. PhrasaLex will take place at Università degli Studi di Modena e Reggio-Emilia, Italy.



June 25, 2019:
A new version of Kind is online



We just added a new function that performs a full autocheck of the results for all hyponyms in each category, flagging those suspected of being errors. For the moment, it does not delete the suspected errors, it just flags them. We will be monitoring this in the next few days and then proceed with the definitive deletion of all suspected errors. Please send us email to alert us if you find something strange in the results.


[UPDATE June 29, 2019]: We just implemented a new algorithm (morfeo) to the filtering process and the quality of the error-detection result has considerably improved. But beware: we are updating the data right now. You might expect some inconsistencies in the process.

Tools & demos

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

+ Bifid: a parallel corpus aligner

+ Dsele: a model dictionary for ELE learners

+ EMaD: automatic categorization of discouse markers

+ Estilector: a tool for assisted writing

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

+ Jaguar: a tool for statistic corpus analysis

+ Kind: a taxonomy induction algorithm

+ Kwico: a concordancer for big corpora

+ Neven: a program to detect eventive nouns

+ Termout: a terminology extraction system

+ POL: named entity recognition and classification

+ Poppins: a supervised text classifier

+ Porcus: an interface for various taggers and parsers for Spanish

+ Sapo: a program to detect similarities between documents

+ Sicam: a Perl implementation of Ricardo Martínez' Excel routine to separate a Spanish Word in syllables (new!)

+ Verbario: corpus pattern analysis in Spanish

Sausalito

This is the view from where we are located, in the Sausalito lagoon, a quiet and lovely place in Viña del Mar, Chile. Sunny days. Birds can be seen in the center of the lagoon (click to enlarge).

As researchers, we are currently affiliated to:

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.
