Methodology
This paper outlines the KDD (Knowledge Discovery from Databases) and DM (Data Mining) approach, leveraging Artificial Intelligence (AI), specifically Decision Trees (J48 algorithm), to predict characteristics of historic buildings. The core idea is to use existing data from archival records and building codes to infer information for buildings where data is missing, thereby reducing on-site research time. The study emphasizes the importance of data discretization, purity metrics (information gain), and validation methods like cross-validation to ensure model accuracy.
Data & Scope
The research focuses on residential buildings with basements and floors built between 1857 and 1948 in the former Austro-Hungarian Empire. Data was collected from provincial archives, building codes (Duchy of Styria 1857, Carniola 1875, etc.), and literature. A database with 2,178 samples and 9 attributes (e.g., storeys, material, wall span, thermal conductivity, year, district) was compiled. The limited availability of digital historical data necessitated a meticulous manual collection and pre-processing effort.
AI Implementation
The Weka software tool was utilized for data mining and decision tree induction, specifically the J48 algorithm (C4.5 extension). The model aims to classify buildings based on attributes like 'Wall Span' to predict their construction period and location. The accuracy varied by algorithm, with J48 achieving 100% accuracy on the training set, indicating strong pattern recognition from the prepared dataset. The decision tree structure, with its clear nodes and leaves, makes the classification process transparent and interpretable for engineers.

Predicting Building Characteristics from Wall Span
The study demonstrated that the 'Wall Span' attribute provides the greatest information gain for classifying historic buildings. If the wall span is >4m, the building is classified to the 1933-1948 construction period. For wall spans <=4m, further classification identifies buildings in Vojvodina Krajnska (<=2m) or Styria (>2m). This insight allows engineers to determine construction periods and territories for buildings with missing records, thereby inferring other characteristics like brick dates and wall thicknesses.
Outcome: Improved efficiency in identifying key building characteristics for undocumented historic structures.

Your AI Implementation Roadmap for Cultural Heritage
A strategic phased approach to integrate AI into your historic building preservation initiatives.
Phase 1: Data Digitization & Archival Integration
Initiate projects to digitize provincial archives and building permits, creating structured, machine-readable datasets. Prioritize key structural elements and material specifications for buildings from the Austro-Hungarian period (1857-1948). Establish a national-level database with robust data governance.
Phase 2: AI Model Development & Validation
Develop and train AI algorithms, starting with decision trees (e.g., J48) and exploring ensemble methods like Random Forest, using the digitized data. Focus on creating predictive models for building characteristics (e.g., material, wall thickness, construction year) based on readily observable attributes like wall span. Implement rigorous cross-validation and accuracy assessments.
Phase 3: Integration with H-BIM & Knowledge Management
Integrate AI models with Historic Building Information Modelling (H-BIM) systems to enrich 3D models with inferred structural data. Develop a knowledge management system that allows engineers, architects, and renovation planners to query and obtain AI-generated insights, speeding up the diagnostic and planning phases of renovation projects. Ensure interoperability with existing AEC tools.
