Natural Language Processing(NLP) and Natural Language Understanding(NLU), along with other technologies like big data analytics form the core part for providing great Conversational experiences.

Though these technologies have been there for many years, it is only recently that they have obtained a level of accuracy for being adopted by people.

In this article, we will understand how important NLP and NLU are across all of your customer service channels. But first, let us have a basic discussion about customer service channels and technologies we are talking about: NLP and NLU.

Understanding different Customer Service Channels

Different customer service channels refer to different mediums in which your customers can engage with you to solve their problems.

Phone calls, live chats and ticket systems are some of the basic examples. However, other forms of channels like Emails, Knowledge bases, forums too provide a great help.

The knowledge bases and forums don't necessarily need to be manually accessed by your customers though, you can use conversational bots that get content from them and serve to customers (more on this later!)

Another channel that is getting popular lately is social media and also messaging apps like Whatsapp to stay in touch with customers! As you may have predicted, those use conversational experiences.

NLU and NLP Explained

Natural language understanding and natural language processing are very much related and have slight differences. If we talk about NLU vs NLP, one is concerned more about understanding semantics and correcting mistakes of natural languages while the other is concerned regarding undresanting entities in language and splitting sentences into tokens etc...

While they might be rule-based initially, many recent versions of NLU and NLP technologies are increasingly reliant on Machine learning, which are basically statistical models that learn to do all of things by themselves without manually providing all the logic when large amounts of training data is given to them.

For once, let us think that you have no NLP & NLU across any customer service channels. Much of everything would have to be done manually by your customers. They need to solve their problem by themselves through Knowledge bases or helping each other out through forums. When they are not able to solve problems, you need to have dedicated staff personnel for live chat, forums and also answer raised tickets. This would be very costly and is also inefficient.

How NLP and NLU help to improve your customer service channels

Rapid response

Customer service chatbot that is powered by NLP and NLU works really fast and can generate responses quickly! No more waiting for any customer service personnel to take up a request and solve it.

Localization

Today’s technology in NLP and NLU helps to provide conversational experiences in various languages. Not only a literal plain translation, they would translate sentences in a way so that original intent and tone of the statement does not change. With this, you can achieve a reasonable localization out of the box!

Sentiment analysis

Conversational experiences powered by NLP and NLU are not only able to understand the general meaning of what customers say but also their emotions. With sentiment analysis, your chatbots can clearly understand how users feel about service and with analyzing many instances, they can provide general insights about the efficacy of customer service.

Integrate knowledge from various sources

There are a lot of sources where useful knowledge exists for customers. Take knowledge bases and forums for instance. With your chatbot readily having access to them, it can easily fetch data that might be or might not be asked directly by the user.

Personalization

Chatbots do not only have immediate information regarding customers but a pool of big data regarding you. With this information, it can easily determine what you need and tailor the entire experience in a way that suits you.

Less cost and low number of employees

Although you have to spend certain time and money on initial training, which is sometimes challenging, in the long run virtual assistants cost fairly less than employing a high number of people for doing the same tasks.

Another main thing to consider is varying volume of requests. In the traditional sense if you hire employees, they are fixed and if an unusually high volume of requests come, they can't handle and if a very low volume of requests come, they sit idle.

Virtual assistant software can easily work with any kind of volume: they scale up fastly when there is a huge need. With this, there would not be any kind of worrying about volume!

Help customer service staff to perform better

Even Though NLP and NLU enabled virtual conversational agents are very powerful, there would be some cases in which they cannot solve the whole issue. In that scenario too they would be useful.

The way they help is to present a complete picture of the problem to your customer service agent. That includes details of conversation, sentiment analysis and also, all of the appropriate data regarding customers.

Along with them there would be many other use cases for NLP in your customer service channels.

Final Words

Recent developments in NLP and NLU along with general artificial intelligence and machine learning has taken them to a level that is highly usable and economical.

Implementing AI enabled conversational experiences in all your customer service channels provide a great advantage through rapid response, personalization and localization, integration of various sources of knowledge and more.

In all senses, NLP and NLU provide great advantages in all customer service channels including Emails, Live Chat, Social media platforms and others.

There are also a lot of platforms and NLP services that provide you out of the box tools that you can easily use to develop your own conversational experiences that satisfy your needs.

Do this and improve customer service engagement and provide an overall positive customer service experience!
