Demystifying Natural Language Processing and Sentiment Analysis

Updated: Oct 18, 2023

If you've ever asked Siri to set an alarm, or watched in awe as Google Translate effortlessly transformed English into French, you've already experienced Natural Language Processing (NLP) in action. But what is it exactly, and how does Siftree leverage it to redefine comment management?


Understanding Natural Language Processing


Natural Language Processing (NLP) is a subfield of artificial intelligence (AI) that focuses on the interaction between computers and humans through natural language. The ultimate goal of NLP is to read, decipher, understand, and make sense of human language in a valuable way.


NLP combines computational linguistics—rule-based methods for language processing—and machine learning, which allows the system to learn from data. The technology can be used in many different ways, from translation and speech recognition to sentiment analysis and information extraction. By bridging the gap between human communication and computer understanding, NLP is enabling a whole new level of interactivity and productivity.


How Does NLP Work?


NLP works in several stages:


  1. Tokenization: This is the process of breaking down text into words, phrases, symbols, or other meaningful elements called tokens.

  2. Stop Word Removal: Common words that do not contain important meaning and are usually removed from texts like 'is', 'an', 'the', etc.

  3. Stemming and Lemmatization: These processes are used to reduce words to their root form. For example, 'running' would be reduced to 'run'.

  4. Part of Speech (POS) Tagging: This involves identifying the grammatical groups of the words such as whether a word is a noun, verb, adjective, etc.

  5. Named Entity Recognition (NER): This is the process of identifying and classifying named entities in text into predefined categories such as person names, organizations, locations, etc.


What is Sentiment Analysis?


Sentiment Analysis, also known as opinion mining, is an NLP technique used to determine whether data is positive, negative, or neutral. It is often used in business to detect sentiment in social data, gauge public opinion, monitor brand and product reputation, and understand customer experiences.


How Does Sentiment Analysis Work with NLP?


Sentiment Analysis works by training an NLP model on a dataset of known sentiment, typically using a labeled corpus of text where each document is marked as 'positive', 'negative', or 'neutral'. This training allows the model to learn and understand the words and phrases indicative of sentiment.


When presented with new, unlabeled text, the trained model can analyze the words and phrases used, and predict the sentiment of the text based on its training. For instance, words like 'love', 'amazing', and 'great' are often associated with positive sentiment, while words like 'hate', 'terrible', and 'awful' are often associated with negative sentiment.
