Twitter sentiment analysis

Abstract

Sentiment analysis is a machine learning technique used to classify the level of sentiment from a text. It could be from the simplest classification of a message according to whether it expresses a positive or negative feeling, to the most complex that it is able to classify text into different emotions. It is a common technique that is used more and more in many companies and sectors, to see people's reaction in front of a new product or service and react to the predictions to offer what the client wants. In this project, sentiment analysis will be applied for the classification of messages on social networks, a very common technique as it is where people express more their feelings without filters, related to Covid-19 and the pandemic we are living in. The aim is to conduct a study to see the emotional tendency of the population in this context.

El sentiment analysis és una tècnica de machine learning utilitzada per a classificar el grau de sentiment d'un text. Existeix des de la més simple classificació d'un missatge segons si expressa un sentiment positiu o negatiu, fins a la més complexa que és capaç de classificar en diferents emocions. És una tècnica que cada vegada és més utilitzada en moltes empreses i sectors, per veure la reacció de la població davant d'un nou producte o servei i reaccionar segons el que el client demana. En aquest projecte, s'aplicarà el sentiment analysis per a la classificació de missatges en xarxes socials, una tècnica molt freqüent, ja que és on la població és més expressiva, relacionats amb la Covid-19 i la pandèmia que estem vivint. L'objectiu és realitzar un estudi per veure la tendència emotiva de la població en aquest context.
