Natural language (NL) processing of NL commands is performed to determine one or more of (i) content to be included in a hypertext document, (ii) a layout for the hypertext document, or (iii) parameters corresponding to behavior of the hypertext document. Performing the NL processing includes: determining assumptions concerning one or both of (a) ambiguities associated with the NL commands or (b) information necessary for creating the hypertext document not specified by the NL commands. The assumptions correspond to the one or more of (i) content to be included in the hypertext document, (ii) the layout for the hypertext document, or (iii) the parameters corresponding to behavior of the hypertext document. Hypertext document code or data for displaying the hypertext document is generated based on the NL processing of the NL commands including the determined assumptions.
