Discourse & Dialogue

Your smart contact center can see how many calls changed from neutral to angry. How many calls changed from angry to happy/neutral. And how many calls changed from neutral to happy. This gives you a new metric to judge agent performance and skill. Recordings where customers are converted from angry to happy can picked out in seconds and used to train agents.

Retailers are increasingly looking to harness the rewards available from social media. Social platforms are already widely used by retailers in an effort to connect with customers in an engaging and authentic manner. Sentiment analysis is used widely, but studies have shown that its accuracy can be as low as 58 per cent. Furthermore, it typically misses detailed signals such as specific nuances within customer concerns, plus emotional intent. Without intent it is hard to take action.

"Learning to choose is hard. Learning to choose well is harder. And learning to choose well in a world of unlimited possibilities is harder still, perhaps too hard." When starting a new NLP sentiment analysis project, it can be quite an overwhelming task to narrow down on a select methodology for a given application. Do we use a rule-based model, or do we train a model on our own data?

Natural Language Processing (NLP) is a subfield of machine learning concerned with processing and analyzing natural language data, usually in the form of text or audio. Some common challenges within NLP include speech recognition, text generation, and sentiment analysis, while some high-profile products deploying NLP models include Apple's Siri, Amazon's Alexa, and many of the chatbots one might interact with online. To get started with NLP and introduce some of the core concepts in the field, we're going to build a model that tries to predict the sentiment (positive, neutral, or negative) of tweets relating to US Airlines, using the popular Twitter US Airline Sentiment dataset. Code snippets will be included in this post, but for fully reproducible notebooks and scripts, view all of the notebooks and scripts associated with this project on its Comet project page. Let's start by importing some libraries.

As a Python developer and data scientist, I have a desire to build web apps to showcase my work. As much as I like to design the front-end, it becomes very overwhelming to take both machine learning and app development. So, I had to find a solution that could easily integrate my machine learning models with other developers who could build a robust web app better than I can. By building a REST API for my model, I could keep my code separate from other developers. There is a clear division of labor here which is nice for defining responsibilities and prevents me from directly blocking teammates who are not involved with the machine learning aspect of the project.

Sentiment analysis is the process of computationally identifying and categorizing opinions expressed in a piece of text, especially in order to determine whether the writer's attitude towards a particular topic, product, etc. is positive, negative, or neutral. In this article, I will show you how to build your own program to determine if an article on a website is positive, negative, or neutral using the Python programming language. If you prefer not to read this post and would like a video representation of it, you can check out the YouTube Video below and the full code on my Github. It goes through everything in this article with a little more detail and will help make it easy for you to start programming your own article sentiment analysis program even if you don't have the programming language Python installed on your computer. Or you can use both as supplementary materials for learning!

Today's marketers are rightfully obsessed with metrics. But don't forget that your customers are more than just data points. And yeah, it's easy to overlook our customers' feelings and emotions, which can be difficult to quantify. However, consider that emotions are the number one factor in making purchasing decisions. With so many consumers sharing their thoughts and feelings on social media, it quite literally pays for brands to have a pulse on how their products make people feel.

After ML.NET Model Builder installation open your Visual Studio (in my case I'm using VS2019) After Project has been selected, enter your Project Name. Select Asp.Net Core template which you want to use, I'm using Web Application MVC. After the project has been created, we will start to build our model. Right-click on Project Add Machine Learning, ML.NET Model Builder tool GUI has been opened. After scenario selection, we will select the data set that will be used to train our model.

Sentiment analysis is not an easy task to perform. Text data often comes pre-loaded with a lot of noise. Sarcasm is one such type of noise innately present in social media and product reviews which may interfere with the results. Sarcastic texts demonstrate a unique behaviour. Unlike a simple negation, a sarcastic sentence conveys a negative sentiment using only positive connotation of words.
