Workshop about Spanish Negation (NEGES) Download provisional proceedings

Negation is a linguistic phenomenon used to modify the truth value of the linguistic unity which applies to, like a proposition, a phrase or word. There are several mechanisms to express negation. The most common are: 1) syntactic negation: using syntactically independent negation particles like ‘never’ 2) lexical negation: created from words with a negation affix (Eg, discontent, incoherent ...).

Treating this phenomenon implies identifying the presence of the negation in the context of the text and determining its scope. Negation is a key aspect of Language Natural Processing areas such as Automated Translation, Sentiment Analysis, Extraction of Information, or Search for Responses.

In the last years this phenomenon has aroused a special interest among the scientific community. Even prestigious researches consider this concept as a challenge in PLN due to its degree of difficulty. Until now, most research has been based on English texts, but the presence of other languages on the Internet is increasing every day.

This workshop aims to study this phenomenon in Spanish, which is the second most widely spoken language in the world and the third most used on the Internet. The main objective is to bring together the scientific community that is working on this topic, and to be able to discuss how this phenomenon is being addressed, what are the main problems encountered, as well as the pooling of resources and tools aimed at negation in Spanish.

Participants must write a paper (6 pages max) about the negation treatment in the Spanish language. These works will be exposed during the workshop with a presentation of no more than 10 minutes. In particular, the works will be about.

  • Works published or ongoing on negation in Spanish
  • Available resources
  • Future work or ideas
  • Negative results
  • Problems encountered and possible solutions
  • Application in PLN tasks
