What is Conversational AI?
Fundamentally, conversational AI is a kind of artificial intelligence (AI) technology that simulates human conversations. It enables computers and software applications to collaborate with humans in a human-like demeanor using spoken/written language. These systems can be implemented in various forms, such as chatbots, virtual assistants, voice-activated intelligent devices, and customer support systems.
How Does Conversational AI Work?
A conversational AI workflow is a collection of various processes. A typical conversation AI works in the following manner.
- Interactive User Interface: It has an interface using which the user inputs text. Alternatively, an ASR (Automatic Speech Recognition) system could record the user’s voice and convert it into text.
- Natural Language Processing: NLP technology is then used to extract the intent from the user input and transform it into structured data to be analyzed.
- Natural Language Understanding (NLU): NLU focuses on extracting the intent and context from the user’s input. It involves analyzing the information to determine the user’s goal or desired action.
- Natural Language Generation (NLG): Response generation using natural language generation (NLG). NLG is used to infer from the above process and generates responses to converse with humans.
Natural Language Understanding (NLU)
As the name suggests, natural language understanding (NLU) is a branch of AI that understands user input using computer software. It helps bridge the gap between the user’s language and the system’s ability to process and respond appropriately.
Importance of Accurate and Context-Aware Language Comprehension
As artificial intelligence advances, more and more companies are adopting AI-based technologies in their operations. Customer services and management is one area where AI adoption is increasing daily. Consequently, AI that can accurately analyze customers’ sentiments and language is facing an upward trend. This reduces the need for human professionals to interact with customers and spend numerous human hours trying to understand them.
NLU Techniques in Conversational AI Systems
NLU is a vital component of all conversational AI systems. To classify intent, extract entities, and understand contexts, NLU techniques often work in conjunction with machine learning. It uses supervised learning, named entity recognition, and deep learning.
- Supervised Learning: Generally, NLU models are trained using supervised machine learning with labeled training data. The training data consists of examples of user inputs and their corresponding intents and entities. Using this data, the NLU model learns to identify patterns and relationships between the input and desired output.
- Named Entity Recognition (NER): NER is a specific NLU technique to identify and classify named entities in text. It extracts entities like names, dates, organizations, or predefined categories.
- Deep Learning: Various NLU tasks utilize recurrent neural networks (RNNs) and transformers to capture more complex patterns in the input data. It helps in understanding intents and extracting entities effectively.
Intelligent Virtual Assistants (IVAs)
Have you interacted with Siri, Cortana, or Alexa? If yes, then you must be familiar with what virtual assistants are. Even if you haven’t, you must have at least heard about them.
