3. The device according to claim 1 , wherein the document interpreter (ID) comprises a semantic analyser (AS) arranged to determine the semantic compatibility relations between principal nodes of the object type and/or principal nodes of the activity type of at least one semantic tree.
1. A device Device (D) for semantic analysis of documents, comprising a computer device, a structural and semantic database (BD) and a document interpreter (ID) arranged so as to determine whether a document has a meaning, using said database, characterized in that the document interpreter (ID) comprises: an n-ary tree controller (GAN) arranged to construct a structural n-ary tree from a breakdown of a document which is to be analyzed into an ordered series of verbal entities and structural and/or semantic constraints selected from and defined in said database (BD), the structural n-ary tree comprising a root node formed by a primary governing verbal entity, and structures formed by a secondary subordinate verbal entity and attached either directly or indirectly to the root node by a link having at least one connectional characteristic, a secondary subordinate verbal entity being in turn capable of becoming a governing verbal entity, a semantic tree controller (GAS) arranged to determine, at least from the structural n-ary tree and the database (BD), categorizing entities of an object type and activity type, activated by certain nodes of the n-ary tree, for constructing a semantic tree provided with principal nodes made up of the categorizing entities of object and activity and linked by semantic relations arising from connectional characteristics of said n-ary tree and with which attributes are associated as a function of the characteristics of other nodes of the n-ary tree and their respective links; wherein the document interpreter (ID) comprises a binary tree controller (GAB) arranged to construct a structural binary tree from said breakdown of a document into an ordered series of verbal entities and structural and/or semantic constraints selected from and defined in said database (BD), the structural binary tree comprising leaves, each associated with a verbal entity of the series and constituting one of two son nodes attached to a father node, and a root node, constituting a father node and associated with all or some of the verbal entities in the series, and in that said n-ary tree controller (GAN) is arranged to construct each n-ary tree from a structural binary tree.
