What is Natural Language Processing NLP Chatbots?- Freshworks

This goes way beyond the most recently developed chatbots and smart virtual assistants. In fact, natural language processing algorithms are everywhere from search, online translation, spam filters and spell checking. Interpreting and responding to human speech presents numerous challenges, as discussed in this article. Humans take years to conquer these challenges when learning a new language from scratch.

A more modern take on the traditional chatbot is a conversational AI that is equipped with programming to understand natural human speech. A chatbot that is able to “understand” human speech and provide assistance to the user effectively is an NLP chatbot. The Natural Language Toolkit (NLTK) is a platform used for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources such as WordNet.

Transfomers and Pretraining

(a) NLP based chatbots are smart to understand the language semantics, text structures, and speech phrases. Therefore, it empowers you to analyze a vast amount of unstructured data and make sense. At its core, the crux of natural language processing lies in understanding input and translating it into language that can be understood between computers. To extract intents, parameters and the main context from utterances and transform it into a piece of structured data while also calling APIs is the job of NLP engines. Machine Language is used to train the bots which leads it to continuous learning for natural language processing (NLP) and natural language generation (NLG).

If you know how to use programming, you can create a chatbot from scratch. If not, you can use templates to start as a base and build from there. The next step in the process consists of the chatbot differentiating between the intent of a user’s message and the subject/core/entity. In simple terms, you can think of the entity as the proper noun involved in the query, and intent as the primary requirement of the user. Therefore, a chatbot needs to solve for the intent of a query that is specified for the entity.

Everything you need to know about an NLP AI Chatbot

Check out these new social media software capabilities that make social publishing and engaging even easier. There are many NLP engines available in the market right from Google’s Dialog flow (previously known as API.ai), Wit.ai, Watson Conversation Service, Lex and more. Some services provide an all in one solution while some focus on resolving one single issue. Session — This essentially covers the start and end points of a user’s conversation.

One of the most important elements of machine learning is automation; that is, the machine improves its predictions over time and without its programmers’ intervention. In a more technical sense, NLP transforms text into chatbot and nlp structured data that the computer can understand. Keeping track of and interpreting that data allows chatbots to understand and respond to a customer’s queries in a fluid, comprehensive way, just like a person would.

Remarkably, within a short span, the chatbot was autonomously managing 10% of customer queries, thereby accelerating response times by 20%. Deploying a rule-based chatbot can only help in handling a portion of the user traffic and answering FAQs. NLP (i.e. NLU and NLG) on the other hand, can provide an understanding of what the customers “say”.

Sparse models generally perform better on short queries and specific terminologies, while dense models leverage context and associations. If you want to learn more about how these methods compare and complement each other, here we benchmark BM25 against two dense models that have been specifically trained for retrieval. Just because NLP chatbots are powerful doesn’t mean it takes a tech whiz to use one. Many platforms are built with ease-of-use in mind, requiring no coding or technical expertise whatsoever.
