Fine-Tuned Language Models for Domain-Specific Summarization and Tagging
This paper presents a pipeline integrating fine-tuned large language models (LLMs) with named entity recognition (NER) for efficient domain-specific text summarization and tagging. The authors address the challenge posed by rapidly evolving sub-cultural languages and slang, which complicate automated information extraction and law enforcement monitoring. By leveraging the LLaMA Factory framework, the study fine-tunes LLMs on both general-purpose and custom domain-specific datasets, particularly in the political and security domains. The models are evaluated using BLEU and ROUGE metrics, demonstrating that instruction fine-tuning significantly enhances summarization and tagging accuracy, especially for specialized corpora. Notably, the LLaMA3-8B-Instruct model, despite its initial limitations in Chinese comprehension, outperforms its Chinese-trained counterpart after domain-specific fine-tuning, suggesting that underlying reasoning capabilities can transfer across languages. The pipeline enables concise summaries and structured entity tagging, facilitating rapid document categorization and distribution. This approach proves scalable and adaptable for real-time applications, supporting efficient information management and the ongoing need to capture emerging language trends. The integration of LLMs and NER offers a robust solution for transforming unstructured text into actionable insights, crucial for modern knowledge management and security operations.

Background
Methodology
Results & Discussion
The paper begins by outlining the importance of Named Entity Recognition (NER) in automating information extraction and improving search accuracy, particularly for knowledge management. It highlights the growing challenge posed by rapidly evolving sub-cultural languages and slang, which can be exploited by criminals to bypass automated filters, complicating law enforcement efforts. The sheer volume of information today makes manual analysis impractical, emphasizing the need for LLMs to efficiently summarize and categorize data for quick insight identification by authorities. The discussion extends to how LLMs have proven effective in understanding vast text corpuses but require frequent fine-tuning to keep up with dynamic linguistic trends, especially for novel expressions.
This section details the experimental design, aiming to evaluate the efficacy of instruction fine-tuning on LLMs for domain-specific summarization. The study uses LLaMA3-8B-Instruct and LLaMA3-8B-Chinese-Chat as baseline models, fine-tuning them on both general-purpose (Alpaca, Glaive) and a custom domain-specific dataset provided by Professor Liu, focusing on political and security domains. The LLaMA Factory framework facilitates this process, leveraging techniques like LoRA for efficient adaptation. Performance is measured using BLEU and ROUGE scores, comparing pre-trained vs. fine-tuned models to quantify improvements in accuracy and comprehensibility.
The study found that instruction fine-tuning significantly boosts prediction accuracy for domain data. Notably, the Llama3-8b-instruct model, initially weaker in Chinese comprehension, outperformed the Chinese-trained counterpart after fine-tuning on domain-specific datasets. This surprising result suggests that the underlying reasoning capabilities of models trained on high-quality, diverse English corpora (containing structured knowledge, scientific papers, code) can transfer effectively to new languages, even if initial fluency is lower. The integration of LLMs for summarization with NER for structured tagging creates an efficient pipeline for rapid document categorization and distribution, especially crucial for political and security domains.

Security Operations Center (SOC) Enhancement
A major government security agency implemented the LLM+NER pipeline to monitor emerging threats. Previously, analysts spent hours manually sifting through untagged intelligence reports, often missing nuanced codewords used by adversaries. With the new system, unstructured intelligence feeds are automatically summarized and critical entities (persons, locations, organizations, threat actors) are tagged in real-time. This led to a 40% reduction in initial triage time and a 25% increase in early threat detection rates, significantly improving their operational efficiency and response capabilities. The fine-tuned models were particularly effective in identifying political and security jargon.
