Natural Language Processing

Innovation and its advancements have gotten fundamental to our way of life in the digital age. In a digitally dominated world, a huge amount of information gets produced each second at an alarming rate. The flood of Big Data and Data Science has made it important to utilize raw information to make a few data-driven decisions. The question remains, how on the planet are we going to deal with this data. The appropriate response is through Natural Language Processing (NLP).

Natural language processing, frequently known as NLP, alludes to the ability of a computer to comprehend human speech as it is spoken. NLP is a key segment of artificial intelligence (AI) and depends on machine learning, a particular type of AI that analyzes and utilizes patterns in information to improve a program’s comprehension of speech.

In simple terms, NLP represents the automatic handling of natural human languages like speech or message, and in spite of the fact that the idea itself is captivating, the real value behind this technology originates from the use cases.

NLP empowers the recognition and prediction of diseases dependent on electronic health records and patient’s own speech. This ability is being explored in health conditions that go from cardiovascular diseases to depression and even schizophrenia. For instance, Amazon Comprehend Medical is a service that utilizes NLP to extricate illness conditions, prescriptions and treatment results from patient notes, clinical trial reports and other electronic health records.

Amazon’s Alexa and Apple’s Siri are instances of smart voice-driven interfaces that utilize NLP to react to vocal prompts and do everything like locate a specific shop, disclose to us the climate forecast, recommend the best course to the workplace or turn on the lights at home. Having an understanding into what’s going on and what individuals are discussing can be truly important to financial traders. NLP is being utilized to follow news, reports, remarks about potential mergers between organizations, everything can be then consolidated into a trading algorithm to create gigantic benefits. Keep in mind: purchase the gossip, sell the news.

NLP is especially booming in the healthcare industry. This innovation is improving care delivery, disease diagnosis and cutting expenses down while healthcare companies are experiencing a growing adoption of electronic health records. The way that clinical documentation can be improved implies that patients can be better comprehended and profited through better healthcare. The objective should be to enhance their experience, and a few companies are as of now taking a shot at this.


Applications of NLP

Text Classification

Wherein text inputs can be sorted by topic or tonality and so on. This application supposedly aids in filtering spam emails, language identification, sentiment analysis (of product reviews) and type characterization (of books, motion pictures, arts and so on).

Language Modeling

Here the computers use NLP to anticipate an appropriate feature or expression dependent on the underlying source of content. It tends to be seen in producing new headlines, new sentences, sections, or documents as well as for anticipating the recommended continuation of a sentence.

Speech Recognition

Here NLP is utilized to make the correct text output dependent on audio info information obtained. Interpreting a speech, subtitle addition and even virtual personal assistants deal with this ability.

Subtitle Generation

Through this, a digital picture/video can be depicted in text structure. It’s not just helpful for the individuals who are visually impaired yet in addition to producing search results of images & videos with respect to input text.

Machine Translation

Here, the input information is interpreted from the first language to another dependent on user demands. These incorporate translating a text document or audio file from any unknown language to English or the other way around.


Advantages of NLP

The advantages of natural language processing are incalculable. Natural language processing can be used by organizations to improve the effectiveness of documentation processes, improve the accuracy of documentation, and distinguish the most appropriate data from large databases. For instance, a hospital may use natural language processing to pull a particular diagnosis from a doctor’s unstructured notes and assign a billing code.

Certainly, it assists organizations with understanding customers better or serving them all the more flawlessly. Having more impressive models of language implies that tasks that computers could scarcely deal with a couple of years back are currently possible. You can mine and sum up user comments, measure their sentiment, extract named entities to perceive what different products and organizations are being examined and how they’re connected, translate between different languages, automate question answering with chatbots, and classify documents and responses dependent on different measurements of similarity and difference. The rundown goes on.

Most convincing of all, there are currently individual models being built up that can sum up to achieve these tasks, which means a possibly immense decrease in the amount of time and effort it recently took when numerous various models were required.
