ArtworkChatAgent Documentation

Overview

The ArtworkChatAgent is a sophisticated AI-powered conversational agent that enables users to have natural language discussions about artworks from multiple perspectives. It leverages Microsoft Semantic Kernel and OpenAI's advanced language models to create immersive, educational experiences around art and cultural artifacts.

Key Features

🎭 Multi-Persona Conversations

  • Artwork Persona: Chat with the artwork itself - hear its "voice", stories, and perspective
  • Artist Persona: Converse with the creator - understand artistic process, inspiration, and techniques
  • Curator Persona: Get expert museum perspective - historical context, acquisition stories, and scholarly insights
  • Historian Persona: Explore historical context - cultural movements, time periods, and influences

👁️ Vision Analysis Capabilities

  • Automatically detects when users ask visual questions about artworks
  • Integrates with OpenAI's vision models (GPT-4V) for detailed image analysis
  • Describes colors, patterns, textures, composition, and artistic elements
  • Provides contextual visual insights based on conversation flow

🧠 Intelligent Memory Management

  • Maintains conversation history across chat sessions
  • Caches conversations for performance optimization
  • Preserves context for more natural, flowing discussions
  • Configurable memory persistence settings

💡 Smart Question Generation

  • Generates contextual follow-up questions based on conversation
  • Creates persona-specific conversation starters
  • Adapts suggestions to user's interests and discussion flow
  • Fallback to curated default questions when needed

📊 Analytics & Performance Tracking

  • Tracks token usage and response times
  • Monitors model performance and vision usage
  • Provides comprehensive chat analytics
  • Enables optimization and cost management

Method Overview

Primary Public Methods

ChatAsync(ChatRequest, CancellationToken)

Purpose: Main conversation method - processes user messages and generates AI responses

Process Flow:

  1. Retrieves and enriches artwork data
  2. Creates appropriate persona handler
  3. Builds conversation history with system prompts
  4. Optionally includes vision analysis for visual questions
  5. Generates AI response using configured settings
  6. Creates suggested follow-up questions
  7. Saves conversation to memory (if enabled)
  8. Returns comprehensive response with analytics

Key Features:

  • Error handling with fallback responses
  • Performance monitoring and logging
  • Configurable AI model settings
  • Vision integration for image analysis

GenerateConversationStartersAsync(ArtworkData, ChatPersona, CancellationToken)

Purpose: Creates engaging opening questions for new conversations

Features:

  • Persona-specific question generation
  • Artwork-contextual suggestions
  • Fallback to curated defaults
  • Async generation with error handling

GenerateSuggestedQuestionsAsync(ArtworkData, string, ChatPersona, CancellationToken)

Purpose: Creates contextual follow-up questions based on conversation flow

Logic:

  • Analyzes conversation context and user's last message
  • Generates persona-appropriate questions
  • Parses and filters AI responses
  • Provides curated fallbacks

AnalyzeArtworkVisuallyAsync(ArtworkData, string?, CancellationToken)

Purpose: Performs detailed visual analysis of artwork images

Capabilities:

  • Describes visual elements, colors, patterns, textures
  • Analyzes composition and artistic techniques
  • Responds to specific visual questions
  • Handles missing images gracefully

Core Private Methods

BuildChatHistory(ChatRequest, ArtworkData, IPersonaHandler)

Purpose: Constructs complete conversation context for AI processing

Components:

  • System prompt from persona handler
  • Historical conversation messages
  • Current user message with optional vision content

AddUserMessageWithVision(ChatHistory, ChatRequest, ArtworkData)

Purpose: Intelligently adds user messages with vision analysis when appropriate

Vision Logic:

  • Detects visual analysis requests through keyword matching
  • Checks for available artwork images
  • Validates vision model capabilities
  • Falls back to text-only when needed

IsVisualAnalysisRequest(string)

Purpose: Determines if user message contains visual analysis keywords

Keywords Detected:

  • Visual: "see", "look", "color", "shape", "pattern", "design", "visual", "appearance"
  • Descriptive: "texture", "carving", "details", "surface", "decoration", "style", "form"
  • Compositional: "composition", "describe", "show", "appears", "seems", "looks like"

Configuration

Usage Examples

Basic Chat Interaction

var request = new ChatRequest
{
    ArtworkId = "artwork-123",
    Persona = ChatPersona.Artwork,
    Message = "Tell me about yourself",
    ConversationHistory = new List<ChatMessage>(),
    IncludeVisualAnalysis = true
};

var response = await chatAgent.ChatAsync(request);

Visual Analysis

var analysis = await chatAgent.AnalyzeArtworkVisuallyAsync(
    artwork, 
    "What colors and patterns do you see in this piece?"
);

Conversation Starters

var starters = await chatAgent.GenerateConversationStartersAsync(
    artwork, 
    ChatPersona.Artist
);
