3 NOTATION RESERVED FOR USE IN THE ANSWER KEYS

3.1 - Expressing Alternative Attribute Values
3.2 - Expressing Optional Markup (STATUS Attribute)
3.3 - Expressing Alternative String Boundaries (ALT Attribute)

3.1 Expressing Alternative Attribute Values

A vertical bar is being used to separate alternative TYPE attribute values in the answer key.

Alternative values will be given when the annotator does not have enough information to make a unique categorization, even considering the context and the annotator's knowledge of the world.

3.2 Expressing Optional Markup (STATUS Attribute)

When it is not certain that a string should be marked up, the annotator will include the STATUS attribute in the markup to indicate that the markup is optional. The only value of the STATUS attribute is "OPT." Examples of its possible use can be found in the appendices, such as in appendix B (holiday names).

3.3 Expressing Alternative String Boundaries (ALT Attribute)

The ALT attribute will be used when the tagged string contains one or more substrings that should be considered correct for the purposes of scoring the system response. Certain premodifiers ("a," "an," and "the") are automatically ignored by the scoring program (via the "configuration" file) and thus do not need to be specially marked in the key.

The ALT attribute will be used sparingly. A possible TIMEX example is shown below.

"all of 1987"

<TIMEX TYPE="DATE" ALT="1987">all of 1987</TIMEX>
