Device and method for semantic analysis of documents by construction of n-ary semantic trees

摘要

A semantic analysis device includes a structural and semantic database and a document interpreter. The document interpreter includes an N-ary tree controller for constructing an N-ary tree from a decomposition of a document and an ordered sequence of verbal entities and structural and/or semantic constraints. The N-ary tree includes a root node formed by a primary verbal entity and structures formed from a subordinate verbal entity related directly or indirectly to the root node by a link having a connecting characteristic. The document interpreter also includes a semantic tree controller for determining object and activity types from the N-ary tree and database, activate by certain nodes of the N-ary tree, for constructing a semantic tree with principal nodes for objects and activities and connected by semantic relationships from connecting characteristics of the N-ary tree, and to which attributes are associated based on other nodes of the N-ary tree.
