1. A method, comprising:

  • obtaining, by a computing device, an incomplete semantic map of a predefined space, wherein the incomplete semantic map includes static landmarks;

    receiving, by the computing device, a set of natural language instructions including a sequence of semantically directive clauses;

    processing, by the computing device, the sequence of semantically directive clauses;

    decoding, by the computing device, one of an action and a path in the set of natural language instructions using an optimization process and based on the incomplete semantic map;

    responsive to the decoding, inserting, by the computing device, a newly identified landmark into the incomplete semantic map;

    executing, by the computing device, the set of natural language instructions along a traveling path;

    detecting, by the computing device, the newly identified landmark; and

    responsive to the detecting of the newly identified landmark, marking, by the computing device, the newly identified landmark as an identified location.
