claimThe study investigates two primary research questions: whether a fine-tuned domain LLM improves performance in knowledge answering, tactical planning, and threat assessment tasks, and whether the proposed domain knowledge graph construction framework generates a high-quality domain knowledge graph.

measurementThe threat assessment task accounts for 20% of the training corpus.

measurementIn threat assessment, there is a 0.01 divergence in Kendall’s Tau between non-desensitized and desensitized data.

procedureThe ablation study in the paper evaluates the contribution of individual components in the proposed framework by systematically removing or disabling key modules and measuring performance on knowledge question answering, tactical planning, and threat assessment tasks.

claimThe researchers constructed evaluation datasets for three specific tasks: knowledge question answering, tactical planning, and threat assessment, ensuring domain complexity aligns with real-world scenarios.

claimThe threat assessment task branch constructs a dynamic risk coefficient matrix by integrating multi-source intelligence and risk assessment models to provide precise battlefield situation judgment.

measurementThe LoRA fine-tuned model achieved a score 16.5% higher than GPT-4 in threat assessment tasks.

measurementExcluding the Task-Adaptive LoRA (TA-LoRA) module from the knowledge graph construction framework resulted in a decrease of 0.08 in Kendall’s Tau for threat assessment tasks.

claimThe task branch set module supports five core tasks: tactical planning, threat assessment, equipment configuration decision-making, instruction parsing, and question answering, by dividing input-output structures based on functional task types.

procedureThe experimental evaluation of the DeepSeek-R1 70B LoRA model uses BERTScore for knowledge question answering, an overall score for tactical planning, Kendall’s Tau for threat assessment, and privacy scores of k-anonymity ≥ 5 and l-diversity ≥ 2.

claimThe desensitization strategy, which applies generalization and masking techniques to raw data, preserves semantic integrity in knowledge question answering, tactical planning, and threat assessment tasks with minimal performance loss compared to non-desensitized approaches.

claimNon-desensitized data occasionally outperforms desensitized data in tasks requiring precise temporal reasoning, such as threat assessment with real-time sensor streams.

claimEffective deployment of Large Language Models (LLMs) in high-security domains requires datasets that are information-rich, highly reliable, structurally consistent, and capable of covering tasks such as tactical decision support, threat assessment, and domain-specific question answering.
