Language models generate text and speech that seem as if a human has written them. The most popular language model GPT which is developed by OpenAI has been trained on a large dataset and mimics human intelligence.

5. Automatic Text Summarization

The processing of long texts into a synopsis of key messages is another area where NLP can be used. 

By summarizing key documents, knowledge workers can save time on information gathering and fasten decision making. It has been predicted that such a use case can help to automate the tasks of even decision-makers. 

Types of NLP

1. Named Entity Recognition

Name Entity Recognition(NER) helps with information extraction by identifying key entities within a text. NER is used in the healthcare industry to extract key information such as patient names, conditions, and treatments.

2. Sentiment Analysis

Among the different types of NLP, sentiment analysis is very popular as it helps to classify emotions from the text which is helpful for applications such as analyzing large numbers of customer reviews fast and with accuracy.

3. Text Summarization

This type of NLP helps to summarize vast amounts of text and extracts the key points to create summaries. It has many applications such as saving time for lawyers to get key points from a large amount of legal documents.

4. Topic Modeling

Topic modeling helps classify topics from texts without the need of human supervision. For instance, companies can use topic modeling to identify the key topics that their followers are discussing regarding their social media profiles.

5. Machine Translation

The use of machine translation helps to translate text or speech from one language to another. This is the same type of NLP that Google Translate has been using to serve more than 1 billion users.

What Are the Benefits of NLP in Business

To make the most out of NLP, it’s necessary to understand how exactly it can help a business. Here are the key benefits of NLP.

1. Efficient customer service

The high interactivity and continuous availability of chatbots created with NLP are able to handle up to 70% of complicated customer service queries. 

As a result, businesses are able to serve their customers more efficiently along with accuracy in their responses.

2. Save time and money

NLP helps to save both time and money by automating tasks and accelerating the speed of existing processes. 

A case in point, trading teams have been using NLP to read tens of thousands of pages of unstructured data in annual reports and security filings to get insights into a company much faster. 

3. Boost your conversion rate

Additionally, NLP benefits businesses by increasing the conversion rate since there are multiple NLP solutions for optimizing websites and applications. This is done by creating personalized messages based on the user’s behavior. 

4. Improve the end-user experience

The advanced functionalities that NLP presents can help to improve the entire experience for the user. For instance, social media platforms use NLP to automatically detect and remove any spam content. 

5. Increase employee satisfaction

Using NLP can help to streamline unfulfilling employee tasks including scanning documents, data entry, and appointment scheduling. 
With NLP, 45% of research analysts estimate that their roles will be significantly different in the coming 5 to 10 years
