But how do we get actual CSAT insights from customer conversations? Text classification is the process of assigning predefined tags or categories to unstructured text. There are two kinds of machine learning used in text analysis: supervised learning, where a human helps to train the pattern-detecting model, and unsupervised learning, where the computer finds patterns in text with little human intervention. Support Vector Machines (SVM) is an algorithm that can divide a vector space of tagged texts into two subspaces: one space that contains most of the vectors that belong to a given tag and another subspace that contains most of the vectors that do not belong to that one tag. Precision states how many texts were predicted correctly out of the ones that were predicted as belonging to a given tag. For example, in customer reviews on a hotel booking website, the words 'air' and 'conditioning' are more likely to co-occur rather than appear individually. This is where sentiment analysis comes in to analyze the opinion of a given text. Machine learning techniques for effective text analysis of social Sentiment analysis uses powerful machine learning algorithms to automatically read and classify for opinion polarity (positive, negative, neutral) and beyond, into the feelings and emotions of the writer, even context and sarcasm. The Azure Machine Learning Text Analytics API can perform tasks such as sentiment analysis, key phrase extraction, language and topic detection.

Go-to Guide for Text Classification with Machine Learning - Text Analytics Essentially, sentiment analysis or sentiment classification fall into the broad category of text classification tasks where you are supplied with a phrase, or a list of phrases and your classifier is supposed to tell if the sentiment behind that is positive, negative or neutral. Once all of the probabilities have been computed for an input text, the classification model will return the tag with the highest probability as the output for that input. By using a database management system, a company can store, manage and analyze all sorts of data. The table below shows the output of NLTK's Snowball Stemmer and Spacy's lemmatizer for the tokens in the sentence 'Analyzing text is not that hard'. Developed by Google, TensorFlow is by far the most widely used library for distributed deep learning. However, it's important to understand that automatic text analysis makes use of a number of natural language processing techniques (NLP) like the below. Machine learning-based systems can make predictions based on what they learn from past observations. Once a machine has enough examples of tagged text to work with, algorithms are able to start differentiating and making associations between pieces of text, and make predictions by themselves. For example, it can be useful to automatically detect the most relevant keywords from a piece of text, identify names of companies in a news article, detect lessors and lessees in a financial contract, or identify prices on product descriptions. Accuracy is the number of correct predictions the classifier has made divided by the total number of predictions. Supervised Machine Learning for Text Analysis in R To see how text analysis works to detect urgency, check out this MonkeyLearn urgency detection demo model. In other words, recall takes the number of texts that were correctly predicted as positive for a given tag and divides it by the number of texts that were either predicted correctly as belonging to the tag or that were incorrectly predicted as not belonging to the tag.
