    • Embodiments include an apparatus comprising a memory hardware coupled to a processor hardware; the memory hardware configured to store a data graph encoding information as a plurality of vertices and interconnections between the plurality of vertices, each vertex representing an entity, each interconnection being directed from one vertex to another vertex, representing a relation of the entity represented by the one vertex to the entity represented by the another vertex, and being assigned a label defining the relation; the processor hardware configured to execute processing instructions stored on the memory hardware causing the processor hardware to: receive an identification of a vertex in the data graph as a subject of a query; in respect of each of a plurality of candidate vertices in the data graph, find paths along interconnections between the respective candidate vertex and the subject of the query, the candidate vertices being a group of vertices from among which a closest match to the subject vertex is required by the query; for each interconnection on each of the paths, obtain a word vector representation of the label assigned to the interconnection generated by forward propagating all or part of the label through a neural language model stored on the memory hardware; for each path, computing a distance measure based on a cumulative sum of the obtained word vector representations of the interconnections on the path; identify the path from among the found paths with the shortest computed distance measure, and output, as a response to the query, the candidate vertex in respect of which the identified path was found.
