What is Natural Language Processing, and Why It’s Important?

Natural Language Processing (NLP), a fascinating subset of artificial intelligence, lies at the intersection of computer science and linguistics. Its primary goal is to enable computers to comprehend and respond to human language just as humans do, which is an incredibly complex task due to the nature of human language.

To “understand” and “generate” human language, computers must recognize spoken or written words, interpret the context, capture the intended sentiment, and detect sarcasm or humor. This comprehension is not just about understanding individual words but also how words in a sentence relate to each other and the message they collectively express.

When we talk about NLP enabling computers to generate human language in a valuable way, computers can create meaningful and relevant responses based on the information they’ve understood. This capacity is evident in Chatbots, voice assistants like Siri or Alexa, or even in Gmail’s predictive text functionality, all of which utilize NLP.

But why is this important in Mobile App?

Natural Language Processing (NLP) is an essential component in mobile applications for several reasons:

1. Enhances User Experience

NLP significantly enhances the user experience by making interactions with the app more natural and intuitive. Users can interact with the app using their natural language, making it easier and more accessible to a broader range of users.

2. Improves User Engagement

NLP can dramatically improve user engagement through features like voice commands, intelligent search, and personalized recommendations. When users find the app more engaging and responsive to their needs, they will likely spend more time on it and recommend it to others.

3. Provides Insights into User Behavior

NLP can analyze user input to provide valuable insights into user behavior, needs, and preferences. This data can then be used to personalize the user experience further and improve the app.

4. Increases App Functionality

NLP opens up new possibilities for app functionality. For instance, it can enable features like real-time language translation, sentiment analysis, and automatic summarization.

5. Automates Customer Service

Integrating NLP in mobile apps enriches the app’s functionality. It transforms how users interact with the app, making it a crucial factor in the success of modern mobile applications.

Real-World Examples of NLP Applications in Businesses

Natural Language Processing (NLP) is a powerful tool integrated into various business applications to improve services, enhance user experience, and streamline operations. Let’s summarize the examples in this section to understand how businesses utilize NLP.

1. Google Translate

Google Translate is a free multilingual translation service provided by Google. It translates text, images, speech, and even real-time video from one language to another. At the heart of Google Translate is NLP. When you enter text to translate, the system breaks down the input into smaller components (a process called tokenization), understands the context, and then reassembles the translation in the target language. This application of NLP enables users to communicate effectively in different languages.

2. Amazon’s Alexa and Apple’s Siri

Alexa and Siri are voice-activated virtual assistants that use NLP to comprehend and respond to user commands. When a user issues a voice command, the assistant uses NLP to break down the spoken sentence into parts it can understand, interpret the meaning of those parts in context, and then perform the requested action. For example, if you tell Alexa to “play my workout playlist,” it recognizes the words, understands that you want to hear music from a specific playlist, and executes the command.

3. AI Chatbots in Customer Service

Many businesses utilize NLP in their Chatbots to provide efficient and interactive customer service. When a customer types a question or statement, the Chatbot uses NLP to understand the query’s intent and generates a suitable response. This process often involves understanding language nuances, interpreting context, and extracting relevant information. NLP allows Chatbots to handle various customer service tasks, from answering frequently asked questions to assist with bookings or orders, enhancing customer experience and operational efficiency.

These real-world examples illustrate how NLP can facilitate seamless interaction between humans and machines, overcome language barriers, and automate tasks, contributing to enhanced services and improved user experiences in businesses.

1. NLP Techniques

Tokenization: Tokenization is breaking down an enormous paragraph into sentences or words. These individual sentences or words are called tokens. Tokenization helps in understanding the context of the text by analyzing each token separately.

Part of Speech Tagging: Part of Speech (POS) Tagging is a process where you label the words in a sentence as nouns, verbs, adjectives, adverbs, etc. The program can use this information to understand the meaning of sentences.

Named Entity Recognition (NER): Named Entity Recognition is used to classify entities in the text into predefined categories such as names of people, organizations, locations, expressions of times, quantities, etc. This helps in understanding the context in which the named entities are used.

Topic Modeling: Topic modeling is a technique to extract hidden topics from large volumes of text. Latent Dirichlet Allocation (LDA) is a popular algorithm for topic modeling which automatically identifies topics in text data.

Sentiment Analysis: Sentiment Analysis is used to identify the sentiment expressed in a series of words, sentences, or paragraphs. It can be used to identify positive, negative, and neutral sentiments. It is commonly used in brand monitoring, understanding customer feedback, and social media monitoring.

2. NLP Algorithms

NLP uses machine learning algorithms and deep learning models to process natural language data.

Decision Trees: Decision trees classify data into predefined classes based on certain conditional control statements. They are simple to understand, easy to visualize, and work well with decision boundaries.

Random Forest: Random Forest is an ensemble learning method that operates by constructing many decision trees at training time and outputting the class that is the mode of the classes (classification) or mean prediction (regression) of the individual trees.

Naïve Bayes: Naïve Bayes classifiers are a family of simple “probabilistic classifiers” based on applying Bayes’ theorem with strong (naïve) independence assumptions between the features. They are highly scalable and suitable for large datasets.

Support Vector Machines (SVM): SVM is used for classification and regression challenges. However, it is mostly used in classification problems in the industry. The SVM algorithm aims to create the best line or decision boundary to segregate n-dimensional space into classes.

Deep Learning Models: Deep Learning is a subset of machine learning that uses neural networks with many layers (deep structures). Because of their ability to learn complex patterns, deep learning models like Recurrent Neural Networks (RNNs) and Transformers are often used for NLP tasks.

Understanding these techniques and algorithms is crucial while working to develop a mobile app using natural language processing, as these techniques form the foundation of your NLP model.
