Military realm entity links based on improved editing distances

Abstract

In order to accurately link the entity references in the commander’s demand statement to the standardized entity nodes in the knowledge graph, an entity linking method in the military domain based on improved edit distance is proposed. By summarizing the non-standard forms of entity referencing to establish an index, and using the BM25 model to integrate the improved edit distance algorithm that considers the character position exchange, inclusion similarity and other similarities, the entities to be linked are sorted to achieve the link. The experimental results show that the entity linking method in the military field can effectively improve the matching accuracy in similarity calculation.
