“…Every word contains in a tweet is important in decision making, so pre-processing of these tweets is an important task because these messages are full of slang, misspellings, and words from other languages [60][61][62][63]. In order to tackle the problems with the noise in texts, normalization of tweets is performed by applying text preprocessing steps like tokenization, stop words removal, stemming, lemmatization, feature weighting, dimensionality reduction, frequency based methods proposed by Bao et .al [62].…”

“…Therefore, pre-processing is typically conducted to convert the text into textual features that could be fit into the SA methods. Once the pre-processed text features are extracted, they are ready to be fit in the next phase of SAFeature Selection [10] [11]. Pre-processing is usually based on NLP techniques such as tokenization (splitting the sentences into words), de-noising (remove special characters, capture symbols for emotions), normalization (remove duplicate characters, identify root words etc.…”

“…For stop words, they constructed list of domain specific stop words which are not standard stop words but carry no information for the specific domain. Bao et al [11] evaluated the effects of text pre-processing in twitter sentiment analysis. They first considered username, hashtags, emotions, digital symbols, single letters, punctuations and other non-alphabetic symbols for de-noising.…”
