Overview

Enterprise-Grade Conversational AI For Contact Centre & Customer Care operations

Kumaran's AI Chatbot is an enterprise-grade Conversational AI assistant built for internal Contact Centre operations. It answers questions raised by Contact Centre Executives on behalf of end customers, drawing exclusively from verified internal documents such as Word files, PDFs, HTML pages, images and SharePoint portals.

Built with a cloud-agnostic approach that supports both cloud and on-prem deployment with major LLM vendor models. The bot is conversational and context-aware, avoids sensitive topics through built-in guardrails and PII filtering, and continuously improves through a structured feedback and fine-tuning loop, supporting scalable and high-availability deployment.

Why This Matters

The Challenges With Conventional Chatbots

Contact centre chatbots built on general-purpose LLMs or simple retrieval approaches face a consistent set of failures in enterprise environments.

Hallucinated Responses

Standard LLM chatbots generate plausible but factually incorrect answers when the right content is not grounded in verified internal documents.

No Follow-Up Understanding

Most bots treat every question as independent, failing to understand follow-up questions that rely on earlier conversational context.

Sensitive Topic Exposure

Without guardrails, bots may respond to prohibited or sensitive queries, creating compliance and reputational risk for the organisation.

Single-Format Knowledge Limits

Many bots only work with one file type, leaving valuable knowledge locked in Word docs, PDFs, HTML pages, images and SharePoint portals untapped.

Slow Knowledge Retrieval

Vector-only or keyword-only search approaches miss the relevance sweet spot, returning imprecise results and degrading response quality.

No Continuous Improvement

Chatbots without a feedback loop cannot learn from Contact Centre Executive corrections, causing persistent errors to go uncorrected over time.

Poor Availability & Resilience

Single-region deployments create single points of failure, risking service outages for business-critical internal support tools.

Access Control Gaps

Without proper authentication and authorisation flows, internal chatbots risk exposing confidential documents to unauthorised users.

Our Solution

Eight Purpose-Built Architectural Capabilities

Kumaran's Conversational AI Bot resolves these challenges through eight purpose-built architectural capabilities.

Hybrid RAG Architecture

Combines semantic vector search and traditional text-mining (unigram, bigram, trigram, phrase and stop-word handling) via Elastic Search for superior retrieval accuracy.

Multi-Format Knowledge Ingestion

A document crawler parses and logically chunks content from Word, PDF, HTML, images, SharePoint and other sources, then embeds and indexes each chunk via OpenAI embeddings.

Conversational Context Handling

The service checks the user's chat transcript for context, rewrites follow-up questions into standalone queries and uses that for retrieval, not for answer generation.

Azure Active Directory Auth

Every query is authenticated against Microsoft Azure Active Directory before processing, ensuring only authorised users access the knowledge base.

Fact-Based Answer Generation

Responses are generated by LLM using only the retrieved, augmented content from the internal knowledge base, preventing hallucination by design.

Feedback-Driven Fine-Tuning

Contact Centre Executives can provide feedback on responses. Issues are categorised and used to continuously fine-tune bot behaviour and improve answer quality.

High-Availability Deployment

Dual-region Azure deployment with Cross-Region Replication, Enterprise Redis and a Traffic Manager ensures resilient, always-on availability.

Sensitive Topic Guardrails

The bot detects greeting, chit-chat, sensitive and out-of-scope queries, responding appropriately without exposing restricted content or fabricating answers.

How It Works

Our Proven Query Flow, From Question To Verified Answer

Every user query follows a 7-step message flow from the chat widget to the verified response.

Step01
User Sends Query
The Contact Centre Executive types a question on behalf of the end customer via the Chat Widget (Single Page App).
Step02
Authentication
The Conversational AI Service authenticates the incoming query against Microsoft Azure Active Directory before any processing begins.
Step03
Context Check & Query Preparation
The service reviews the user's chat transcript for conversational context and rewrites the question into a clean, standalone search query.
Step04
Knowledge Base Search
The rewritten query is passed to Elastic Search, which performs a hybrid search combining semantic vector matching and keyword text-mining across the indexed knowledge base.
Step05
Content Augmentation
The Conversational AI Service prepares the retrieved content as augmented context and submits it to OpenAI LLM for answer generation.
Step06
Response Delivered To User
LLM generates a fact-based response using only the augmented knowledge-base content. The response is returned to the Chat Widget.
Step07
Chat Transcript Archived
On conversation end or session timeout, the full chat transcript is moved to Cosmos DB for audit, analysis and future fine-tuning.
