Common NLP tasks and techniques. Sentiment analysis

#artificialintelligence

Sentiment analysis, also known as opinion mining, is the process of determining the attitude or emotion of the writer towards a particular topic. Sentiment analysis is used in a wide range of applications, such as market research, brand management, and political analysis. There are several techniques used in sentiment analysis, including lexicon-based methods, which use a predefined list of words and their associated sentiment, and machine learning-based methods, which use algorithms to learn patterns in the data. Text classification is the process of automatically categorizing text into predefined categories or labels. Text classification has a wide range of applications, including spam detection, sentiment analysis, and topic classification.


Fine-Tuning of a Sentiment Analysis Task with Transformers-TensorFlow on Apple M1 Chip

#artificialintelligence

A simple guide to fine-tuning a Transformers DistilBert Model using Tensorflow on Apple M1 Chip for a Sentiment Analysis Task. During the execution of the model.fit() After investigation, I found this solution that works for TF2.6 and forces the GPU as the only device available to run the network Read the CSV file and apply a lambda function to convert labels from text to numbers. Label positive is 1 and label negative is 0. The dataset will be split into training, validation, and testing, according to the percentages of 70, 15, and 15. For this copy-paste tutorial, the distilbert-base-uncased has been used, so the DistilBertTokenizerFast is used to tokenize the dataset, the output is in numpy form.


Flipkart Reviews Sentiment Analysis using Python

#artificialintelligence

Flipkart is one of the most popular Indian companies. It is an e-commerce platform that competes with popular e-commerce platforms like Amazon. One of the most popular use cases of data science is the task of sentiment analysis of product reviews sold on e-commerce platforms. So, if you want to learn how to analyze the sentiment of Flipkart reviews, this article is for you. In this article, I will walk you through the task of Flipkart reviews sentiment analysis using Python.


AI Integrated Patients Sentiment Analysis

#artificialintelligence

In order to comprehend how the text is organised, syntactic and semantic methods were being used (to identify meaning). Lemmatization, tokenization, and part-of-speech tagging are some of these approaches.After the text has been cleaned up using NLP methods, machine learning algorithms may classify it. Computers could now detect patterns in data and forecast events thanks to machine learning. So instead explicit instructions, machine learning algorithms get their cues from example that are close to them (training data). If you desire your model to be able to classify text according to sentiment, you must train it with examples of textual emotions.


How AI-driven sentiment analysis can enhance employee satisfaction

#artificialintelligence

Check out all the on-demand sessions from the Intelligent Security Summit here. With tech talent in short supply, companies are desperate to hold onto top performers. However, many are losing ground. Employees are sticking around for much shorter periods than they used to. Sentiment analysis combined with artificial intelligence (AI) is being harnessed to help companies in a number of ways: Discovering how employees feel about their work environment, how effective they feel training and skill development initiatives are, and what their concerns are, and how to spot danger signs, identify signs of burnout, identify indicators of job dissatisfaction, and prevent employees from jumping ship rivals.


Sentiment Analysis on Encrypted Data with Homomorphic Encryption - KDnuggets

#artificialintelligence

It is well-known that a sentiment analysis model determines whether a text is positive, negative, or neutral. However, this process typically requires access to unencrypted text, which can pose privacy concerns. Homomorphic encryption is a type of encryption that allows for computation on encrypted data without needing to decrypt it first. This makes it well-suited for applications where user's personal and potentially sensitive data is at risk (e.g. This blog post uses the Concrete-ML library, allowing data scientists to use machine learning models in fully homomorphic encryption (FHE) settings without any prior knowledge of cryptography.


Twitter Sentiment Analysis with Hugging Face

#artificialintelligence

Sentiment analysis is a type of NLP that aims to label data according to its sentiments, such as positive, negative, and neutral. This analysis helps companies understand how their customers feel about their products or services or identify trends in public opinion about a particular topic. For example, a company like Audi can learn whether people like the colors of its new car by examining Twitter shares like the image below. With the developing technology, it is now much easier to express all kinds of emotions, feelings, and thoughts through social networking sites. Social media scraping is the process of extracting data from social media platforms.


Topic Modeling -- Intro and Implementation

#artificialintelligence

Businesses interact with their customers to better understand them and also to improve their products and services. This interaction can take the form of emails, textual social media posts (e.g. It would be inefficient and cost-prohibitive to have human representatives look through all of these forms of textual communications and then route the communications to the relevant teams to review, take action on and/or respond to customers. One inexpensive method to group such interactions and to assign them to relevant teams is using topic modeling. Topic modeling in the context of Natural Language Processing (NLP) is a type of unsupervised (i.e.


Why Companies Should Invest in Sentiment Analysis

#artificialintelligence

Monitoring and examining sentiments have become increasingly popular with brands focused on automating their business processes. Mainly known as an innovative tool used by social media and marketing analysts, sentiment analysis, sometimes referred to as "social listening," has also proved helpful in other functional areas. We explain why companies should invest in sentiment analysis. Insight engines allow to use sentiment analysis across the enterprise and doesn't limit the tool to just one business need. Without machine learning (ML), methods like natural language processing (NLP) sentiment analysis would be unachievable.


Can an AI recognize my opinion from tweets?

#artificialintelligence

To make a long story short: In principle; yes. And if my colleagues at the University of Edinburgh are to be believed, it even works in cases where an opinion is not explicitly expressed. In fact, the terms "sentiment analysis" or "opinion mining" are nothing new to people who deal with language technology. However, this is not infrequently a marketing ploy: because what sounds like opinion analysis is in fact usually nothing more than a polarity analysis of the feelings that are transported via a text. In other words, it analyzes whether a social media post has positive or negative vibes.
