Sentiment Analysis with Deep Learning by Edwin Tan It features automatic documentation matching, search, and filtering as well as smart recommendations. This solution consolidates data from numerous construction documents, such as 3D plans and bills of materials (BOM), and simplifies information delivery to stakeholders. Spiky is a US startup that develops an AI-based analytics tool to improve sales calls, training, and coaching sessions. The startup’s automated coaching platform for revenue teams uses video recordings of meetings to generate engagement metrics. Below you see the vectors for a hypothetical news article for each group using a bag-of-words approach. These are the class id for the class labels which will be used to train the model. Sawhney et al. proposed STATENet161, a time-aware model, which contains an individual tweet transformer and a Plutchik-based emotion162 transformer to jointly learn the linguistic and emotional patterns. Fine-grained analysis delves deeper than classifying text as positive, negative, or neutral, breaking down sentiment indicators into more precise categories. In positive class labels, an individual’s emotion is expressed in the sentence as happy, admiring, peaceful, and forgiving. The language conveys a clear or implicit hint that the speaker is depressed, angry, nervous, or violent in some way is presented in negative class labels. Mixed-Feelings are indicated by perceiving both positive and negative emotions, either explicitly or implicitly. Finally, an unknown state label is used to denote the text that is unable to predict either as positive or negative25. How to use sentiment analysis A sentiment analysis tool uses artificial intelligence (AI) to analyze textual data and pick up on the emotions people are expressing, like joy, frustration or disappointment. Decoding those emotions and understanding how customers truly feel about your brand is what sentiment analysis is all about. If you are looking for the most accurate sentiment analysis results, then BERT is the best choice. However, if you are working with a large dataset or you need to perform sentiment analysis in real time, then spaCy is a better choice. If you need a library that is efficient and easy to use, then NLTK is a good choice. Sawhney et al. proposed STATENet161, a time-aware model, which contains an individual tweet transformer and a Plutchik-based emotion162 transformer to jointly learn the linguistic and emotional patterns. Furthermore, Sawhney et al. introduced the PHASE model166, which learns the chronological emotional progression of a user by a new time-sensitive emotion LSTM and also Hyperbolic Graph Convolution Networks167. It also learns the chronological emotional spectrum of a user by using BERT fine-tuned for emotions as well as a heterogeneous social network graph. Moreover, many other deep learning strategies are introduced, including transfer learning, multi-task learning, reinforcement learning and multiple instance learning (MIL). Rutowski et al. made use of transfer learning to pre-train a model on an open dataset, and the results illustrated the effectiveness of pre-training140,141. Ghosh et al. developed a deep multi-task method142 that modeled emotion recognition as a primary task and depression detection as a secondary task. Then, slowly increase the number to verify capacity and quality until you find the optimal prompt and rate that fits your task. For this subtask, the winning research team (i.e., which ranked best on the test set) named their ML architecture Fortia-FBK. This section describes and analyses the dataset description, experimental setup, and experiment results. Annette Chacko is a Content Strategist at Sprout where she merges her expertise in technology with social to create content that helps businesses grow. In her free time, you’ll often find her at museums and art galleries, or chilling at home watching war movies. Google Cloud Companies can deploy surveys to assess customer reactions and monitor questions or complaints that the service desk receives. Sentiments from hiring websites like Glassdoor, email communication and internal messaging platforms can provide companies with insights that reduce turnover and keep employees happy, engaged and productive. Sentiment analysis can highlight what works and doesn’t work for your workforce. It requires accuracy and reliability, but even the most advanced algorithms can still misinterpret sentiments. Accuracy in understanding sentiments is influenced by several factors, including subjective language, informal writing, cultural references, and industry-specific jargon. Continuous evaluation and fine-tuning of models are necessary to achieve reliable results. IBM Watson Natural Language Understanding (NLU) is an AI-powered solution for advanced text analytics. Moreover, the Gaza conflict has led to widespread destruction and international debate, prompting sentiment analysis to extract information from users’ thoughts on social media, blogs, and online communities2. Israel and Hamas are engaged in a long-running conflict in the Levant, primarily centered on the Israeli occupation of the West Bank and Gaza Strip, Jerusalem’s status, Israeli settlements, security, and Palestinian freedom3. Moreover, the conflict in Hamas emerged from the Zionist movement and the influx of Jewish settlers and immigrants, primarily driven by Arab residents’ fear of displacement and land loss4. Additionally, in 1917, Britain supported the Zionist movement, leading to tensions with Arabs after WWI. The Arab uprising in 1936 ended British support, resulting in Arab independence5. In recent years, NLP has become a core part of modern AI, machine learning, and other business applications. Similar to XLM-R, it can be fine-tuned for sentiment analysis, particularly with datasets containing tweets due to its focus on informal language and social media data. However, for the experiment, this model was used in the baseline configuration and no fine tuning was done. Similarly, the dataset was also trained and tested using a multilingual BERT model called mBERT38.

These steps are performed separately for sentiment analysis and offensive language identification. The pretrained models like Logistic regression, CNN, BERT, RoBERTa, Bi-LSTM and Adapter-Bert are used text classification. The classification of sentiment analysis includes several states like positive, negative, Mixed Feelings and unknown state. It contains
