Abstract: 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.

Abstract: The invention relates to a device (D), for the semantic analysis of documents, comprising a structural and semantic database (BD) and a document interpreter (ID) comprising i) an N-ary tree controller (GAN) for the construction of a structural N-ary tree from a decomposition of a document for analysis and an ordered sequence of verbal entities and structural and/or semantic constraints, said structural N-ary tree comprising a root node for a primary controlling verbal entity and structures formed from a subordinate secondary verbal entity related directly or indirectly to the root node by a link provided with at least one connecting GAN characteristic, a secondary subordinate verbal entity being able to itself become a controlling verbal entity and ii) a semantic tree controller (GAS) for determination of entities characterising object and activity types from the N-ary structural tree and the database (BD), activated by certain nodes of the N-ary tree in order to construct a semantic tree provided with princi
