An old-growth forest — also termed primary forest, virgin forest, primeval forest, late seral forest, or forest primeval — is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris.
A forest fire danger report semantic analysis method based on a knowledge graph
The present application relates to a kind of forest fire danger based on knowledge graph's semantic analysis method of report, belong to natural language processing technical field.It includes the following steps: collection original forest fire danger report text, constructs forest fire danger report data set;Forest fire danger report semantic analysis model is constructed, including knowledge subgraph construction and coding module, deep fusion representation generation module, graph convolution calculation module and multi-task output module;Through multi-task collaborative loss function, forest fire danger report semantic analysis model is trained and optimized, and the trained forest fire danger report semantic analysis model is obtained;New forest fire danger report text is input to the trained forest fire danger report semantic analysis model, and the forest fire danger report semantic analysis result is obtained.The present application can realize the fine modeling of the evolution logic of forest fire danger professional field, and enhance the explainability of result.
