    Evaluación de rendimiento de diferentes modelo grandes de lenguaje para el reconocimiento de emociones en texto
    (Universidad EAFIT, 2024) López Atehortúa, David Alejandro; Montoya Múnera, Edwin Nelson
    It is becoming more common for people to express their opinions in short texts through different media thanks to the expansion of internet access. Understanding and efficiently analyzing an individual’s sentiment from a text is a task that is useful in multiple scenarios. For the above, a branch of computer science called Natural Language Processing (NLP) has been dedicated to developing techniques to understand everything related to human language. Traditional techniques, based on the frequency of a word or a group of consecutive words to classify the text in a positive, negative or neutral sentiment. These techniques have limitations because they fail to capture the full context of each word in a sentence, affecting their accuracy and ability to detect a more detailed spectrum of emotions. Recently, Long Language Models (LLMs) or Transformers revolutionized the way NLP is performed thanks to their ability to capture the context around each word in a text. This allows for the detection of feelings in a more precise way and even, the classification of the text into a more specific emotion such as joy, optimism, anger, sadness or others. This project aims to evaluate the performance of different LLMs to find the best performing one in emotion detection from short texts in English using datasets typically used in research related to NLP models.
