Forum Expression Conversion for Threat Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in collecting and analyzing threat information from hacker forums due to the unstructured and mixed nature of data, which includes forum expressions like contractions and collapsed words, making it difficult to extract relevant threat information accurately using models trained on official security reports.
Innovation Solution
An information analyzing apparatus with a detection unit to identify unknown words and a conversion unit that converts forum expressions into formal expressions using pre-defined conversion information, allowing threat information to be analyzed even in documents with forum expressions, thereby improving analysis accuracy without the need for dedicated models or manual data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a model trained on official security reports is used to analyze threat information, then analysis accuracy is improved, but the ability to handle forum expressions deteriorates
Solution Approach 1:
The patent introduces an intermediary conversion process that translates forum expressions into formal expressions before analysis. The conversion unit acts as a mediator between the informal hacker forum text and the formal analysis model, enabling the model to accurately analyze threat information while adapting to the unique expression styles of hacker forums.
2Measurement precision
If manual extraction of threat information is performed, then analysis accuracy is improved, but productivity deteriorates
Solution Approach 1:
The system enables self-service automation where the conversion unit automatically translates forum expressions and the analysis unit processes threat information without requiring manual intervention. This automated pipeline maintains high analysis accuracy while significantly improving productivity by eliminating manual extraction processes.
Solution Approach 2:
The patent replaces manual mechanical extraction processes with automated computational systems. The detection unit, conversion unit, and analysis unit work together as an automated pipeline that substitutes human analysts' manual work with algorithmic processing, maintaining accuracy while dramatically improving extraction efficiency.
3Adaptability or versatility
If a dedicated model for hacker forums is created, then adaptability to forum expressions is improved, but device complexity increases
Solution Approach 1:
The patent segments the processing system into distinct functional units: a detection unit for identifying forum expressions, a conversion unit for translating them to formal expressions, and an analysis unit for processing the converted text. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining high adaptability to forum expressions.
Solution Approach 2:
The conversion unit performs preliminary action by pre-converting forum expressions into formal expressions before the analysis unit processes the text. This preliminary conversion step simplifies the analysis process and reduces the complexity required in the analysis model itself, as it only needs to handle formal expressions rather than both informal and formal variants.
