Temporal Expression Recognition and Normalization Task Guidelines for Participants
Valentina Bartalesi, Rachele Sprugnoli · 2007
Task Definition In the Temporal Expression Recognition and Normalization task, systems are required to recognize the Temporal Expressions occurring in a text by identifying their extension, and to normalize them, i.e. give a representation of their meaning by assigning values to a pre-defined set of attributes. The task will be based on the TIMEX2 standard, with some adaptations to Italian (see Magnini 2007). Both development data and test data are part of the Italian Content Annotation Bank (I-CAB) and will be distributed upon acceptance of the agreement terms for a free research licence. Two evaluation conditions will be supported for the evaluation. When participants submit their system output for scoring, they must identify which of these two conditions they wish to be evaluated on: Recognition only Recognition + Normalization It is possible to submit a maximum of two runs for each subtask.
