Harmonising Heterogeneous Data Sources for Comprehensive Forensic Analysis
Bibliographic record
Abstract
New techniques must be devised to integrate data types for extensive and accurate analysis as digital forensics evolves. Five key algorithms are recommended for a full framework in this study. Cross-platform normalization for standardization, semantic integration for common representation, federated learning for collaborative analysis, ontology-driven anomaly detection, and blockchain-enhanced chain of custody. The semantic integration algorithm creates a common vocabulary, maps data sources, and standardizes data first. Future algorithms employ this common representation to handle standardization, joint analysis, anomaly detection, and ownership tracking concerns. The ablation research details what each software undertakes to improve and adapt to real-time changes. The proposed performance evaluation system is more accurate, safer, customizable, and effective than present techniques. Federated learning allows numerous analysts to work together while protecting data, while ontology-driven anomaly detection detects anomalies with data consistency. Blockchain-Enhanced Chain of Custody makes Common Representation more dependable by employing a safe and independent blockchain. Forensic research in evolving data systems presents challenges, which this paradigm addresses. The offered methodologies give specialists additional tools to combine and assess multiple types of data, providing a full and flexible solution for current forensic investigations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
