Artificial Intelligence is one of the most innovative technological breakthroughs of the modern times. From daily lives to corporate cultures, everything is being impacted by the novel technology. Artificial Intelligence (AI) strategically improves business processes by giving managers the power to analyze a vast amount of valuable data derived from customers as well as employees. When it comes to human resources, AI is particularly solving one of the greatest issues managers have been facing for many years- to improve employee engagement and retention rates. AI has the potential to give managers the power to make a better workplace, where employees don't feel distracted or dissatisfied with their job roles.
If you have a model that has acceptable results but isn't amazing, take a look at your data! Taking the time to clean and preprocess your data the right way can make your model a star. In order to look at scraping and preprocessing in more detail, let's look at some of the work that went into "You Are What You Tweet: Detecting Depression in Social Media via Twitter Usage." That way, we can really examine the process of scraping Tweets and then cleaning and preprocessing them. We'll also do a little exploratory visualization, which is an awesome way to get a better sense of what your data looks like!
Text Analytics is the process of converting unstructured text data into meaningful data for analysis, to measure customer opinions, product reviews, feedback, to provide search facility, sentimental analysis and entity modeling to support fact based decision making. Text analysis uses many linguistic, statistical, and machine learning techniques. Text Analytics involves information retrieval from unstructured data and the process of structuring the input text to derive patters and trends and evaluating and interpreting the output data. It also involves lexical analysis, categorization, clustering, pattern recognition, tagging, annotation, information extraction, link and association analysis, visualization, and predictive analytics. Text Analytics determines key words, topics, category, semantics, tags from the millions of text data available in an organization in different files and formats.
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.
We're excited to announce an end-to-end solution that leverages natural language processing to analyze and visualize unstructured text in your Amazon Elasticsearch Service domain with Amazon Comprehend in the AWS Cloud. You can deploy this solution in minutes with an AWS CloudFormation template and visualize your data in a Kibana dashboard. Amazon Elasticsearch Service (Amazon ES) is a fully managed service that delivers Elasticsearch's easy-to-use APIs and real-time capabilities along with the availability, scalability, and security required by production workloads. Amazon Comprehend is a fully managed natural language processing (NLP) service that enables text analytics to extract insights from the content of documents. Customers can now leverage Amazon ES and Amazon Comprehend to index and analyze unstructured text, and deploy a pre-configured Kibana dashboard to visualize extracted entities, key phrases, syntax, and sentiment from their documents.
