4.4 Ambiguous Match

The query "example circle" produces the response "Did you mean 'red circle'(1) or 'green circle'(2)?" In this case, the second token of the query is matched to the lower-level match pattern "circle" but is ambiguous between the higher-level match patterns "red" and "green," so the match is ambiguous, and the system seeks to resolve the ambiguity.

This query also illustrates the "hyperlink" feature of DOTGO. In reply to the above response, the query "1" is equivalent to the query "example red circle." Similarly, the query "2" is equivalent to the query "example green circle." In this case, the hyperlinks were generated automatically by the system, although CMRL allows arbitrary hyperlinks to be specified.
