By Sonaksh Singh Rawat on 3/7/2024 · 5 minute read

Chatbots have been a part of the IT world for quite some time, yet they continue to be a topic of interest. Surveys indicate that 34% of consumers believe chatbots assist in connecting them with human customer service, this further highlights the usefulness of these tools. The introduction of natural language processing (NLP) has significantly improved daily life, evidenced by the fact that 84% of consumers use NLP at home, and 27% utilize it in their workplaces.

Thanks to advancements in NLP technology, chatbots have evolved to engage in conversations that are strikingly similar to human interactions.

What is a chatbot?

Chatbots are software solutions designed to simulate human conversations. They excel at completing tasks, achieving goals, and delivering results effectively. Thanks to natural language processing and machine learning, the conversations facilitated by chatbots are virtually indistinguishable from those with humans.

By utilizing advanced algorithms, chatbots are equipped to comprehend natural language and provide contextually relevant responses. In various fields, ranging from customer service to healthcare, chatbots are revolutionizing the way individuals engage with technology, simplifying many aspects of daily life.

What is an NLP chatbot?

NLP or natural language processing plays a pivotal role in facilitating human-to-machine communications, eliminating the need for humans to master programming languages like Java. The distinction between the language used by humans for interpersonal communication and the programming language or the chatbot leveraging NLP is significant.

NLP serves as the bridge, translating human language, such as English, into a format that machines can comprehend, without requiring the intricate knowledge of programming languages like Java.

How to build a chatbot using NLP?

This article outlines steps to consider when building a chatbot using Natural Language Processing (NLP):

1. Analyze the business logic

The analysis of business logic is essential for developers to understand their clients thoroughly.

To achieve this understanding, a discovery phase is undertaken. This phase involves analyzing the business logic, examining the competitive market, and outlining the essential features that the future product should possess. Following these steps leads to the creation of a solid business logic for the product, ensuring a comprehensive assessment of its relevance and potential in the market.

2. Stack of technologies and channels

Several platforms and frameworks are available for chatbot construction, including popular options such as BotPenguin, Dialogflow, Botpress, and Rasa.

For those interested in developing a voice chatbot, the BotPenguin platform is often recommended. In contrast, Telegram, Viber, or Hangouts serve as suitable channels for crafting text chatbots.

When it comes to the technical stack essential for chatbot development, the most common technologies include:

  • Python – A programming language employed to design the architecture of the chatbot.
  • Pandas – This involves libraries for data manipulation and analysis in Python.
  • Twilio – A service that allows software developers to make and receive phone calls, send and receive text messages, and perform other conversational activities through its APIs.
  • TensorFlow - Utilized for machine learning and neural network tasks, this library is a favored choice among developers.
  • SpaCy – Known for its advanced natural language processing capabilities, it is an open-source library.
  • Telegram, Viber, or Hangouts APIs – These APIs are crucial for integrating the chatbot with various messengers or websites.

3. Integration of NLP and development

The initial steps in creating a machine learning chatbot involve the development of a client-side bot and its connection to a provider’s API, such as Telegram, Viber, Twilio, among others. Incorporating NLP (Natural Language Processing) through the application of artificial intelligence can be considered once the development phase is completed.

4. Testing

Testing the chatbot with actual users and making adjustments based on their feedback is crucial. Manual testing is a viable option due to the limited number of scenarios that require checking. This process is crucial in determining the performance of the AI NLP chatbot.

How does NLP work in a chatbot?

An NLP chatbot offers significant assistance by allowing customers to simply type their requests, reducing confusion and frustration. Incorporating various techniques is essential to add more dimensions to information processing in language management. Understanding various principles of language processing is crucial at the beginning of working with NLP.

The process involves four key steps:

  • Morphology: This determines the structure and relationship of words.
  • Syntax: The Syntax dictates the order of words to form coherent sentences.
  • Semantic studies: It reveals the meaning of words through lexical and grammatical structures.
  • Pragmatics: It deals with the contextual meaning of words.

Primarily, adapting the language for computational understanding involves using syntactic and semantic analyses to make data interpretation and cleaning more efficient.
