Constructing a Tactical Mission Event Logic Graph (TMELG) can assist military staff to analyze the composition and evolution process of tactical missions. We can construct Military Internet of Things (MIoT) applications based on the TMELG to assist military staff to make planning and study tactical missions in the Network-Centric Warfare situation. In this paper, we proposed a representation framework for tactical mission events, based on the Simple Event Model (SEM), to present and construct the TMELG. First of all, sub-mission events and event elements are extracted from military texts with an invented Two-Stage Event Extraction (TSEE) method. Secondly, the Hierarchical Task Network (HTN) was applied to decompose a tactical mission into sub-missions, which were further decomposed into atomic missions, then basic relations were established for sub-missions. Finally, we exploited the explicit causality among sub-mission events, and the implicit causality between atomic mission events and military resources with the Granger Causality Model (GCM). With respect to automatic extraction of sub-mission events and event elements from military texts, the experimental results showed that our TSEE method outperforms the listed methods. The successful application of TMELG to a joint landing operation case verifies the feasibility of our construction method proposed in this paper. |
