A review on sentiment analysis and emotion detection from text PMC

Detection of emotion by text analysis using machine learning

how do natural language processors determine the emotion of a text?

Instead of calculating only words selected by domain experts, we can calculate the occurrences of every word that we have in our language (or every word that occurs at least once in all of our data). This will cause our vectors to be much longer, but we can be sure that we will not miss any word that is important for prediction of sentiment. Emotion detection helps companies analyze customer experience so that you can know what elements of your product and service need attention and improvement. Though natural language processing tasks are closely intertwined, they can be subdivided into categories for convenience. We have developed animations corresponding to the six emotions recognized by our detection model to enhance the web application’s user experience. These animations were created by Vladimír Hroš and are visualized in Figure 7 (positive emotions) and Figure 8 (negative emotions).

In the second group, the emotional Classification is compared with results when using various characteristics and coefficients. According to the text analysis, the provinces’ analysis’s detection results vary with different emotions. Each lateral row is the actual outcome, and the result obtained is every lateral row. Multiple regression is a visual tool that enables us to identify and confuse every type of feeling. Bing Liu is a thought leader in the field of machine learning and has written a book about sentiment analysis and opinion mining. Sentiment analysis can be used on any kind of survey and qualitative – and on customer support interactions, to understand the emotions and opinions of your customers.

Proven and tested hands-on strategies to tackle NLP tasks

Deep learning consists of CNN and Bi-GRU, and machine learning consists of an SVM classifier. It starts with input datasets, which are fed into the word embedding layer, i.e., word2vec. After getting the embedding vector, it needs to be fed into both the deep learning algorithms, namely, CNN and Bi-GRU. From CNN and Bi-GRU models, we have removed the last layer, and so they will act as encoders [28]. Table 3 describes various machine learning and deep learning algorithms used for analyzing sentiments in multiple domains. Many researchers implemented the proposed models on their dataset collected from Twitter and other social networking sites.


Following code can be used as a standard workflow which helps us extract the named entities using this tagger and show the top named entities and their types (extraction differs slightly from spacy). Spacy had two types of English dependency parsers based on what language models you use, you can find more details here. Based on language models, you can use the Universal Dependencies Scheme or the CLEAR Style Dependency Scheme also available in NLP4J now.

It is the confluence of human emotional understanding and machine learning technology. A Bidirectional GRU [25] is a sequence processing paradigm made up of two GRUs working together. One provides feedback in a forward direction, and the other in a backward direction. Just the input and output gates are used in this bidirectional recurrent neural network. After feature extraction, the embedding layer of size (18210, 300) will be input for the Bi-GRU model shown in Figure 6. The training vector will be given as an input into the Bi-GRU model to predict the emotions for the data.

Businesses use massive quantities of unstructured, text-heavy data and need a way to efficiently process it. A lot of the information created online and stored in databases is natural human language, and until recently, businesses could not effectively analyze this data. In order to negotiate this skill divide, companies have developed software that gives business analysts the ability to conduct powerful text analysis projects without having to code themselves. Low code tools like Graphext offer access to built-in NLP algorithms including topic detection, sentiment analysis and entity extraction. Confining NLP models to specific tasks allows researchers to focus on improving the accuracy of models built to achieve specific tasks. Because the focus of research is often driven by market demand, sentiment analysis models are generally accepted to be more advanced than models that detect irony.

There are four main ways in which an ML platform can detect emotion in data. Repustate has helped organizations worldwide turn their data into actionable insights. Learn how these insights helped them increase productivity, customer loyalty, and sales revenue. Animations of positive emotions Joy, Love and Surprise created by Vladimír Hroš (surprise can be a positive as well as a negative emotion). A simple illustration of our web application’s functioning is in Figure 6. In this figure, given the sentence “I am feeling very good right now,” the model detects the emotion of Joy in this sentence, with a probability of 99.84%.

Associating words with one another has huge potential in the field of text analytics. The image below represents a keyword analysis built with Graphext in which the significant terms in a text field have been extracted and linked to other, semantically similar significant terms. Document retrieval is the process of retrieving specific documents or information from a database or a collection of documents. Neri Van Otten is a machine learning and software engineer with over 12 years of Natural Language Processing (NLP) experience.

Tagging Parts of Speech

The emotional analysis of all human responses in the whole communication with chatbot and the evaluation of this analysis. The illustration of functioning of web application using the model for emotions detection. • The result of the emotion detection is supplemented with the animation of the detected emotion. • Negations processing is used when negation before a word changes the polarity of a connected word. The most used negation processing methods are the switch and the shift negation. Improved communication between a chatbot and a human through recognition of the human’s emotional state.

  • Using NLP, sentiment analysis algorithms are built to assist businesses to become more efficient and decrease the level of hands-on labor needed to process text data.
  • Namely, the positive sentiment sections of negative reviews and the negative section of positive ones, and the reviews (why do they feel the way they do, how could we improve their scores?).
  • The key part for mastering sentiment analysis is working on different datasets and experimenting with different approaches.
  • NLP techniques improve the effectiveness of methods for teaching by integrating semantic and syntactic text characteristics.

As with the basic model of ML and DL, we get better results, but they are not the best results. The ML approach will give the best accuracy for different types of emotions, and the same for the DL approach. Several studies have used various techniques to detect emotions from text [3–7].

Though not without its challenges, NLP is expected to continue to be an important part of both industry and everyday life. Syntax and semantic analysis are two main techniques used with natural language processing. Now that everyone’s remote, people are using systems to check if people are cheating. Well, that’s problematic, because an algorithm just can’t detect all the nuances, right? That doesn’t seem like a well-thought-out solution — just applying machine learning to that problem.

  • As for the administration, the most commonly and frequently asked questions from students to the institution can be answers via our chatbot to ease out the cycle and ensure a faster and effective resolution to their problems.
  • They can assist with library catalog searches, recommend resources based on subject areas, provide citation assistance, and offer guidance on library policies.

In this article, we’ll explore how ChatGPT is revolutionizing education and helping students achieve their goals. Multilingual chatbots act as friendly language ambassadors, breaking down barriers for students from diverse linguistic backgrounds. Their ability to communicate in various languages fosters inclusivity, ensuring that all students can learn and engage effectively, irrespective of their native language. Through this multilingual support, chatbots promote a more interconnected and enriching educational experience for a globally diverse student body.

Discover content

Handle student applications, course registration, finance and billing, FAQs, tutoring support, results, timetables, and curriculum advising – all automated. For the best outcomes, it is important to capture these insights and map them to your CRM to get qualitative insights that help you engage with students better and guide them throughout their journey at university. For example, queries related to financial aid, course details, and instructor details often have straightforward answers, or the student can be redirected towards the right page for information. Pounce helped GSU go beyond industry standards in terms of complete admissions cycles.

With their ability to automate tasks, deliver real-time information, and engage learners, they have emerged as powerful allies. Artificially intelligent chatbots do not only facilitate student’s learning process by making it more engaging, short and snappy and interesting but also assist teachers by easing out their teaching processes. Our chatbots are designed to engage students with different media to take a break from heavy text-based messages and enjoy some graphically pleasing learning content. This does not only increases the potential to learn quickly but develops an interest in the longer run.

The future of customer experience is conversational. Join us today.

As an example of an evaluation study, the researchers in (Ruan et al., 2019) assessed students’ reactions and behavior while using ‘BookBuddy,’ a chatbot that helps students read books. The researchers recorded the facial expressions of the participants using webcams. It turned out that the students were engaged more than half of the time while using BookBuddy. Chatbots have been found to play various roles in educational contexts, which can be divided into four roles (teaching agents, peer agents, teachable agents, and peer agents), with varying degrees of success (Table 6, Fig. 6).

Best AI Chatbots for Education

Only a few studies partially tackled the principles guiding the design of the chatbots. For instance, Martha and Santoso (2019) discussed one aspect of the design (the chatbot’s visual appearance). This study focuses on the conceptual principles that led to the chatbot’s design. Concerning the platform, chatbots can be deployed via messaging apps such as Telegram, Facebook Messenger, and Slack (Car et al., 2020), standalone web or phone applications, or integrated into smart devices such as television sets. with one another in group chats, grasp each other’s perspectives and difficulties, and even assist one another with questions.

The bot then analyzes the feedback, compiles the highlighted points mentioned by most of the students, and send it to the teachers. CourseQ is a chatbot that is created to help the students, college groups, and teachers by providing them an easy platform to communicate. The college group can use it to broadcast messages and answer students’ queries.

What are the top Benefits of using Chatbots for Educational Apps?

We need to understand the fact that integrating a chatbot to a classroom will be an essential part of education since the time is running fast and the leap into the education system has been taken by technology years ago. As soon as a student clicks ‘Get Started’ the chatbot welcomes and responds to student queries with detailed information. If need be, students can get in touch with a human support representative by clicking ‘Human Help’ in the top menu. Since the world is filled with millions of prospective students enrolling into colleges and universities across the globe, the number of queries each institution or consultancy receives over its website is humongous.

By leveraging chatbot technology, educators can improve the quality of education, reduce workload, and provide students with the support they need to succeed. As chatbot technology continues to evolve, we can expect to see more innovative use cases in the education sector. Moreover, according to Cunningham-Nelson et al. (2019), one of the key benefits of EC is that it can support a large number of users simultaneously, which is undeniably an added advantage as it reduces instructors’ workload.

Evaluation studies

With artificial intelligence, the complete process of enrollment and admissions can be smoother and more streamlined. Administrators can take up other complex, time-consuming tasks that need human attention. Educational institutions are adopting artificial intelligence and investing in it more to streamline services and deliver a higher quality of learning. Students now have access to all types of information at the click of a button; they demand answers instantly, anytime, anywhere. Technology has also opened the gateway for more collaborative learning and changed the role of the teacher from the person who holds all the knowledge to someone who directs and guides instead.

Only two studies presented a teachable agent, and another two studies presented a motivational agent. Teaching agents gave students tutorials or asked them to watch videos with follow-up discussions. Peer agents allowed students to ask for help on demand, for instance, by looking terms up, while teachable agents initiated the conversation with a simple topic, then asked the students questions to learn. Motivational agents reacted to the students’ learning with various emotions, including empathy and approval. The teaching agents presented in the different studies used various approaches.

How to create chatbots for Education Institutions?

They can act as virtual tutors, providing personalized learning paths and assisting students with queries on academic subjects. Additionally, chatbots streamline administrative tasks, such as admissions and enrollment processes, automating repetitive tasks and reducing response times for improved efficiency. With the integration of Conversational AI and Generative AI, chatbots enhance communication, offer 24/7 support, and cater to the unique needs of each student.


In comparison, chatbots used to teach languages received less attention from the community (6 articles; 16.66%;). Interestingly, researchers used a variety of interactive media such as voice (Ayedoun et al., 2017; Ruan et al., 2021), video (Griol et al., 2014), and speech recognition (Ayedoun et al., 2017; Ruan et al., 2019). Pérez et al. (2020) identified various technologies used to implement chatbots such as Dialogflow Footnote 4, FreeLing (Padró and Stanilovsky, 2012), and ChatFuel Footnote 5. The study investigated the effect of the technologies used on performance and quality of chatbots. I think you seem convinced that using a chatbot for education at your institute will prove beneficial.
