The ROBOT TALK corpus was created with the aim of serving as a language sample to perform the quantitative and qualitative contrastive linguistic analyses in order to answer the main question of the project: is it possible to distinguish whether a text in Spanish has been generated by an LLM or by a person using linguistic features of the text?

This is a comparable monitor corpus in Spanish. It is composed of author-comparable texts (human, Bard, Claude, GPT-3.5-Turbo, GPT-4, Mixtral, DeepSeek) of three main genres (news, film reviews and scientific articles specialised in linguistics).
