Military Information Extraction techniques are interested for military managers and commanders. But usual information extraction techniques cannot be used for that domain, because military corpus has special structure that differs from non-military corpus. In this paper the military documents structure is compared with non-military documents structure. Moreover a new classification is proposed for military documents. IE system effects are also surveyed for each class. Then a new composite approach is proposed according to the experimental results. The new approach is based on Wrapper Induction and CRF Model. Test bed is also prepared from battlefield reports to evaluate the proposed system. The improvement is shown based on tow metrics namely Recall and F-Measure. The usefulness of the proposed system is also demonstrates.

 
Keywords: Military Document, Information Extraction (IE), Conditional Random Field (CRF), Wrapper Induction (WI)
