What is NLP? Natural Language Processing for building conversational experiences

By March 7, 2023December 13th, 2023No Comments

A good NLP engine is highly crucial for making conversational experiences work because it ensures accurate speech recognition and natural language understanding. Accuracy is highly significant because a voice assistant must be able to correctly interpret the user’s spoken words to respond appropriately.

It ensures a good conversation flow which refers to the sequence of interactions that occur between the user and the computer. NLP engines facilitate the conversation by anticipating the user’s needs and providing relevant information or assistance at the right time. Keeping the user’s context in mind is another important aspect as it helps to understand where the user is in the conversation and what he is trying to accomplish.

What is NLP and how It powers Conversational Experiences?

NLP is a subfield of artificial intelligence that focuses on the interaction between computers and human language. It entails instructing computer systems to comprehend, decipher the natural language, and generate responses.

It is an interdisciplinary field that draws on many different areas of study, including computer science, linguistics, and psychology. It involves developing algorithms and models that can analyze and understand natural language, as well as tools and applications that can be used to process natural language data.

NLP helps in understanding the user’s intent by analyzing the natural language input. This involves identifying the keywords and entities, extracting the meaning, and identifying the user’s intent. It helps in understanding the context of the conversation, which is important in providing a relevant and personalized response. Contextual awareness involves considering the user’s history, previous interactions, and preferences.

Overall, NLP is a critical component in powering conversational experiences and conversational AI, enabling systems to understand, interpret, and generate natural language responses that are relevant, personalized, and engaging.

NLP techniques and approaches

NLP is an umbrella term covering highly intricate processes where each process is entwined with another:

  • Natural language understanding (NLU): It is the process of understanding the semantics of a language. It can be used to identify the meaning of words and phrases, extract information from text, and generate meaningful responses.
  • Natural language analysis (NLA): It is the process of understanding the structure of a language. NLA is used to identify the parts of speech, identify the relationships between words, and extract the meaning of a sentence.
  • Tokenization: This step in NLP is performed to break down the text into individual words, phrases, or sentences. This process is known as tokenization. Tokenization involves splitting a sentence into words and removing punctuation and other non-essential elements. Tokenization helps to structure the data and makes it easier for machines to process it.
  • Part-of-Speech Tagging: Once the text has been tokenized, the next step is to assign each word a part-of-speech (POS) tag. POS tagging is the process of categorizing each word in a text into its grammatical category, such as noun, verb, adjective, adverb, or preposition. This is an important step in NLP, as it helps machines to understand the meaning of a sentence based on the roles played by different words.
  • Parsing: Parsing is the process of analyzing a sentence to determine its grammatical structure. In NLP, parsing involves breaking down a sentence into its constituent parts, such as subject, verb, object, and so on. This helps machines to understand the relationship between different parts of a sentence and the overall meaning of the sentence.
  • Named Entity Recognition (NER): Named entity recognition (NER) is a technique that involves identifying and classifying named entities in text. Named entities are specific objects, people, places, organizations, or other entities that have a unique name.
  • Sentiment analysis: It is the process of analyzing text to determine the emotional tone of a sentence or document. Sentiment analysis uses NLP techniques to identify words and phrases that are associated with positive or negative emotions and assign a sentiment score to a piece of text.


The success of these voice assistants/chatbots is directly proportional to the robustness and the accuracy of the NLP engine that is powering the voice assistant.

A good NLP engine is highly crucial for making voice assistants work because it ensures accurate speech recognition and natural language understanding. Accuracy is highly significant because a voice assistant must be able to correctly interpret the user’s spoken words to respond appropriately.

In conclusion, natural language processing technology plays a critical role in the development of conversational experiences as it allows users to communicate with computers using natural language. Conversational experiences offer many benefits, including improved customer engagement, increased efficiency, and reduced costs. However, designing effective conversational experiences requires careful planning and attention to detail. Alan AI does that for your business by following the best practices and addressing challenges such as reduced ambiguity which powers conversations that are engaging, intuitive, and effective.
