WHY INVEXUS.AI?

Artificial Intelligence in the Valuation Process

The real estate valuation sector is becoming increasingly complex with growing transaction volumes, constantly updated regulatory requirements, diversifying property types, and rising quality expectations. Experts must navigate hundreds of pages of standards and regulations while finding the most accurate references among thousands of comparable records, preparing reports with methodological consistency, and completing all of this within tightening deadlines.

Banks expect not only accurate results from valuation firms, but also fast delivery, full compliance with technical specifications, transparent methodology, and traceable processes. Meeting these expectations is becoming increasingly difficult with traditional methods. Valuation firms working with AI-powered systems can automatically check compliance with bank technical specifications, shorten report delivery times, perform comparable analyses on broader and more up-to-date data sets, and achieve a consistent quality standard in every report. This directly increases the valuation firm's credibility and preference rate in the eyes of banks.

This transformation is critical not only for valuation experts but also for auditors. Auditors are responsible for simultaneously reviewing dozens of reports, verifying regulatory compliance in each, checking methodological consistency, and detecting standard deviations. INVEXUS.AI significantly lightens this burden by offering auditors automatic consistency checks, regulatory reference matching, and standard compliance verification. This allows auditors to reduce time spent on routine checks and focus on critical evaluations requiring real expertise.

AI technologies are no longer a future vision but the current reality of the sector. Globally, AI-based decision support systems are rapidly spreading in financial services and real estate sectors; valuation firms that keep up with this transformation gain a distinct competitive advantage. With INVEXUS.AI, valuation firms can carry out this transformation securely, in a controlled manner, and within their own infrastructure.

When properly designed, AI does not replace the expert, but multiplies the expert's power.

HOW DOES THE AI WORK?

INVEXUS.AI Intelligent Core Engine

Large Language Model (LLM)
Fine-Tuned Language Model
A natural language understanding and generation engine specialized in valuation terminology, Turkish regulatory language and sector-specific concepts. Optimized specifically for the sector, unlike general-purpose AI.
Sector-Specific Fine-Tuning
RAG Architecture
Retrieval-Augmented Generation
Works by referencing current and verifiable sources, not just model knowledge, for response generation. Each response is linked to source documents, minimizing hallucination risk.
Source-Referenced Response
NL2SQL Engine
Natural Language to SQL
Converts natural language queries into secure SQL expressions. Provides multi-criteria data access without technical knowledge through query optimization, authorization control and data masking layers.
Natural Language Query
Embedding
Semantic Search
Context
WHAT INFORMATION DOES IT ACCESS?

Knowledge Sources & Vector Database

Reference Knowledge Base

Document pool integrated into RAG architecture, accessible through semantic search

International Standards
IVS/UDES, TUDES, IUK 311 and related valuation standards
Regulations & Directives
TDUB, SPK, BDDK regulations and communiques, regulatory body guides, legal texts
Bank Technical Specifications
Client bank/institution-specific technical requirements and best practice guides
Corporate Archive
Firm-specific past report archives, comparable data sets, corporate memory
Vector Database Infrastructure

All documents are indexed using vector embedding and searched semantically

Semantic Embedding
Documents converted to semantic vectors enabling contextual search
Chunk & Index
Fast context matching through optimal chunking and indexing
Version Control
Regulatory and standard changes are tracked, current version referenced
Multi-Tenant Isolation
Each valuation firm's vector space is isolated, cross-corporate data transfer prevented
Compute
IS THE DATA SECURE?

Security, Isolation & Audit Layer

On-Premise
All computation is performed on Key Yazilim's own servers; data is not transferred to cloud or third-party services, no external data export.
Data Isolation
Query, understanding, source access and response generation all occur within the valuation firm's internal infrastructure; data flow does not exit to external networks.
Multi-Tenant
Each valuation firm's data is logically isolated; data or context leakage between firms is technically prevented.
RBAC
Role-based access control is fully integrated with INVEX-D; user permissions are centrally managed, unauthorized access is blocked.
Audit Trail
All query-response interactions are logged with user and timestamp information; source references create an audit trail, regulatory compliance is supported.
Hardware
WHERE DOES IT RUN?

Physical Infrastructure — National Data Center

GPU Computing Servers
Next-generation NVIDIA or equivalent GPU servers; providing high parallel processing capacity for training, fine-tuning and inference of large language models (LLM). Thousands of vectors can be processed simultaneously, accelerating comparable analysis and NLP tasks.
Low-Latency Inference
Model inference and vector search operate with millisecond-level latency; instant responses provided to users through query optimization, caching and load balancing.
Vector Database Cluster
High-capacity, distributed vector storage infrastructure; used for semantic similarity search across millions of records in TDUB, regulatory texts, SPK and other related standards and comparable databases.
Data Sovereignty
All data and hardware hosted within Turkey's borders, in Key Yazilim's own infrastructure at a national data center. Data sovereignty, local storage and audit capabilities compliant with TDUB, KVKK, SPK and bank requirements.
