Abstract:

Monitoring weapons proliferation requires detecting and tracking weapons transfers. Many public sources of weapons-transfer data come from incomplete and manually collected and maintained government and commercial records. We propose a technique to gather weapons-transfer information by mining publicly available Web pages for features, which we categorize as arms, actions, actors, or money. We design a retrieval system and parser, and develop techniques for extracting currency values from text, measuring precision without available training data, and measuring recall with a parallel but different corpus. Results show that, of the sentences matching four feature categories, 70 of relevant features were found, and sentences that only matched three categories introduced more false positives. We conclude that such a technique can improve the speed at which transfer information is compiled.
