“…Research fields related to natural language processing, e.g. information retrieval [1], [2], document classification [3], named entity recognition [4], machine translation [5], sentiment analysis [6], [7], recommendation systems [8] or audience segmentation [9], [10] have in common that they are problems of perception related to our senses. Thus, they have always represented a great challenge for researchers because it is particularly difficult to describe a text using algorithms and mathematical formulas.…”

<span lang="EN-US">Word embedding has become the most popular method of lexical description in a given context in the natural language processing domain, especially through the word to vector (Word2Vec) and global vectors (GloVe) implementations. Since GloVe is a pre-trained model that provides access to word mapping vectors on many dimensionalities, a large number of applications rely on its prowess, especially in the field of sentiment analysis. However, in the literature, we found that in many cases, GloVe is implemented with arbitrary dimensionalities (often 300d) regardless of the length of the text to be analyzed. In this work, we conducted a study that identifies the effect of the dimensionality of word embedding mapping vectors on short and long texts in a sentiment analysis context. The results suggest that as the dimensionality of the vectors increases, the performance metrics of the model also increase for long texts. In contrast, for short texts, we recorded a threshold at which dimensionality does not matter.</span>
