Our evaluation was based on four metrics, precision, recall, F1 score, and specificity. Our results indicate that Google Translate, with the proposed ensemble model, achieved the highest F1 score in all four languages.

• Sprout’s AI can detect sentiment in complex sentences and even emojis, giving you an accurate picture of how customers truly think and feel about specific topics or brands.
• The context of the YouTube comments, including the author's location, demographics, and political affiliation, can also be analyzed using deep learning techniques.
• Most machine learning algorithms applied for SA are mainly supervised approaches such as Support Vector Machine (SVM), Naïve Bayes (NB), Artificial Neural Networks (ANN), and K-Nearest Neighbor (KNN)26.

Similarly for offensive language identification the states include not-offensive, offensive untargeted, offensive targeted insult group, offensive targeted insult individual and offensive targeted insult other. Finally, the results are classified into respective states and the models are evaluated using performance metrics like precision, recall, accuracy and f1 score. Sentiment analysis is a process in Natural Language Processing that involves detecting and classifying emotions in texts. The emotion is focused on a specific thing, an object, an incident, or an individual. Although some tasks are concerned with detecting the existence of emotion in text, others are concerned with finding the polarities of the text, which is classified as positive, negative, or neutral.

LSTM is the most widespread DL architecture applied to NLP as it can capture far distance dependency of terms15. GRUs implemented in NLP tasks are more appropriate for small datasets and can train faster than LSTM17. Precision, Recall, Accuracy and F1-score are the metrics considered for evaluating different deep learning techniques used in this work. Bidirectional Encoder Representations from Transformers is abbreviated as BERT. It is intended to train bidirectional LSTM characterizations from textual data by conditioning on both the left and right context at the same time. As an outcome, BERT is fine-tuned just with one supplemental output layer to produce cutting-edge models for a variety of NLP tasks20,21.

It depends mainly on the mathematical manipulation of the polarity scores, which differs from the unsupervised machine learning methodology. The hybrid approaches (Semi-supervised or weakly supervised) combine both lexicon and machine learning approaches. It manipulates the problem of labelled data scarcity by using lexicons to evaluate and annotate the training set at the document or sentence level. Un-labelled data are then classified using a classifier trained with the lexicon-based annotated data6,26. NLP tasks were investigated by applying statistical and machine learning techniques.

It’s the foundation of generative AI systems like ChatGPT, Google Gemini, and Claude, powering their ability to sift through vast amounts of data to extract valuable insights. Sentiment analysis lets you understand how your customers really feel about your brand, including their expectations, what they love, and their reasons for frequenting your business. In other words, sentiment analysis turns unstructured data into meaningful insights around positive, negative, or neutral customer emotions. One significant challenge in translating foreign language text for sentiment analysis involves incorporating slang or colloquial language, which can perplex both translation tools and human translators46. Slang and colloquial languages exhibit considerable variations across regions and languages, rendering their accurate translation into a base language, such as English, challenging.

Persons can express any sentiment about anything uploaded by people on social media sites like Facebook, YouTube, and Twitter in any language. Pattern recognition and machine learning methods have recently been utilized in most of the Natural Language Processing (NLP) applications1. Each day, we are challenged with texts containing a wide range of insults and harsh language. Automatic intelligent software that detects flames or other offensive words would be beneficial and could save users time and effort. These works defy language conventions by being written in a spoken style, which makes them casual.

It can also be used as a framework for word representation to detect psychological stress in online or offline interviews. GloVe is an unsupervised learning example for acquiring vector representations of words. It collects and aggregates global word-to-word co-occurrences from the corpus for training, and it returns a linear substructure of all word vectors in a given space. BERT is an innovative model which applies bidirectional training of transformers. BERT uses Transformers, and it learns the relation between a word to another word (or sub-words) in the given text of contextual nature. In its initial form, BERT contains two particular tools, an encoder for reading the text input and a decoder for the prediction.

This kind of breakdown is much more helpful for understanding the range of sentiment in the dataset. This shows that both corpuses are similar, but the Hate Speech label has slightly more negative tweets, on average. It’s interesting that a majority of tweets in both classes were deemed pretty neutral, but at least we have a clear breakdown. Ultimately, these scores seem to be not representative of the tweets in this dataset, where the text ranges from hate speech to offensive language. Let’s see what VADER can do with this type of dirty, nonsensical social media data.

NLP algorithms detect and process data in scanned documents that have been converted to text by optical character recognition (OCR). This capability is prominently used in financial services for transaction approvals. While the Deepgram system can better determine sentiment than text-based methods alone, detecting sarcasm can be a little trickier.

Another potential challenge in translating foreign language text for sentiment analysis is irony or sarcasm, which can prove intricate in identifying and interpreting, even for native speakers. Irony and sarcasm involve using language to express the opposite of the intended meaning, often for humorous purposes47,48. For instance, a French review may use irony or sarcasm to convey a negative sentiment; however, individuals lacking fluency in French may struggle to comprehend this intended tone. Similarly, a social media post in German may employ irony or sarcasm to express a positive sentiment, but this could be arduous to discern for those unfamiliar with language and culture. To accurately identify sentiment within a text containing irony or sarcasm, specialized techniques tailored to handle such linguistic phenomena become indispensable.

Pattern provides a wide range of features, including finding superlatives and comparatives. It can also carry out fact and opinion detection, which make it stand out as a top choice for sentiment analysis. The function in Pattern returns polarity and the subjectivity of a given text, with a Polarity result ranging from highly positive to highly negative. Breaks down sentiment indicators into more precise categories, such as very positive, positive, neutral, negative and very negative.

Sentiment analysis is a natural language processing technique that involves using machine learning algorithms to identify and extract subjective information from text data. It is commonly used to determine the overall sentiment of a piece of writing, whether it is positive, negative, or neutral. This can be useful for a variety of applications, such as analyzing customer feedback, detecting the sentiment of social media posts, or identifying the sentiment of movie reviews. Sentiment analysis algorithms typically use a combination of natural language processing techniques and machine learning algorithms to process and analyze text data and can be trained to recognize various types of sentiment.

Still, as an AI researcher, industry professional, and hobbyist, I am used to fine-tuning general domain NLP machine learning tools (e.g., GloVe) for usage in domain-specific tasks. This is the case because it was uncommon for most domains to find an out-of-the-box solution that could do well enough without some fine-tuning. GloVe32 ChatGPT is a distributed word representation model derived from Global Vectors. The GloVe model is an excellent tool for discovering associations between cities, countries, synonyms, and complementary products.

This section analyses the performance of proposed models in both sentiment analysis and offensive language identification system by examining actual class labels with predicted one. The first sentence is an example of a Positive class label in which the model gets predicted correctly. The same is followed for all the classes such as positive, negative, mixed feelings and unknown state.

Machine and deep learning algorithms usually use lexicons (a list of words or phrases) to detect emotions. A machine learning sentiment analysis system uses more robust data models to analyze text and return a positive, negative, or neutral sentiment. Instead of prescriptive, marketer-assigned rules about which words are positive or negative, machine learning applies NLP technology to infer whether a comment is positive or negative. Another approach involves leveraging machine learning techniques to train sentiment analysis models on substantial quantities of data from the target language. This method capitalizes on large-scale data availability to create robust and effective sentiment analysis models.

Applying the data shuffling augmentation technique enhanced the LSTM model performance40. In another context, the impact of morphological features on LSTM and CNN performance was tested by applying different preprocessing steps steps such as stop words removal, normalization, light stemming and root stemming41. It was reported that preprocessing steps that eliminate text noise and reduce distortions in the feature space affect the classification performance positively. Whilst, preprocessing actions that cause the loss of relevant morphological information as root stemming affected the performance. Also, in42, different settings of LSTM hyper-parameters as batch size and output length, was tested using a large dataset of book reviews. In addition to gated RNNs, Convolutional Neural Network (CNN) is another common DL architecture used for feature detection in different NLP tasks.
