A great variety of text tasks such as topic or spam identification, user profiling, and sentiment analysis can be posed as a supervised learning problem and tackle using a text classifier. A text classifier consists of several subprocesses, some of them are general enough to be applied to any supervised learning problem, whereas others are specifically designed to tackle a particular task, using complex and computational expensive processes such as lemmatization, syntactic analysis, etc. Contrary to traditional approaches, we propose a minimalistic and wide system able to tackle text classification tasks independent of domain and language, namely µTC. It is composed by some easy to implement text transformations, text representations, and a supervised learning algorithm. These pieces produce a competitive classifier even in the domain of informally written text. We provide a detailed description of µTC along with an extensive experimental comparison with relevant state-of-the-art methods. µTC was compared on 30 different datasets. Regarding accuracy, µTC obtained the best performance in 20 datasets while achieves competitive results in the remaining 10. The compared datasets include several problems like topic and polarity classification, spam detection, user profiling and authorship attribution. Furthermore, it is important to state that our approach allows the usage of the technology even without knowledge of machine learning and natural language processing.

“…Similarly, some researchers proposed to apply textual features like n-grams, bag of words (BOW), and term frequency-inverse document frequency (TF-IDF) in machine learning algorithms to classify sentiments [13], [18], [19]. On the other hand, some researchers devised a hybrid technique, which combines lexicon and machine learning together to recommend sentiments [14], [16], [20].…”

“…Over the past, machine learning and lexicon-based techniques have been used for sentiment classification. Some researchers modeled features to enhance the functionality of the learning algorithms [13], [18], [19]. However, feature modeling requires careful shortlisting of the discriminating features; Deep learning automatically learns discriminating features from the data.…”

Sentiment classification is an active area of research with applications in many domains. Many researchers in the past have proposed techniques to identify sentiments with reasonable accuracy. However, the focus is more on the syntactic and semantic features of the documents. These features are effective but they ignore the user's past sentiments. In this research, we hypothesize that the past sentiments help the classifier to effectively link the user's history along with the contents of the current tweet. Thus, allowing learning algorithms to correlate past activities in determining the current sentiments. For this sake, we propose three sliding window features to accumulate past sentiments from the time series data. In this paper, we propose seven variations of Context-aware Sliding Window (CSW) features on different machine learning and deep learning algorithms. Furthermore, we propose a temporal dataset of user tweets, which is manually labeled by nine human annotators. The proposed dataset consists of 36 users having 4,557 tweets. Results indicate significant improvements over six state-of-the-art baseline methods.

“…They also use the model to identify the target of the opinions, the product or the video itself. Tellez et al (2017) proposed an extensive list of features that can be used to polarity assignment. These features were grouped in two sets -the cross-lingual and the language dependent.…”
