    La información temporal ayuda a organizar la información textual situando las acciones y los estados en el tiempo. Por eso, es importante identificar los puntos e intervalos temporales en el texto, así como los tiempos a los que estos se refieren. Hemos desarrollado EusHeidelTime para la extracción y normalización de expresiones temporales para el euskera. Para ello, hemos analizado las expresiones temporales en euskera, hemos creado las reglas y recursos para la herramienta y hemos construido un corpus para el desarrollo y la evaluación. Finalmente, hemos realizado un experimento para evaluar el rendimiento de EusHeidelTime. Hemos conseguido resultados satisfactorios en una lengua con morfología rica.

    Temporal information helps to organise the information in texts placing the actions and states in time. It is therefore important to identify the time points and intervals in the text, as well as what times they refer to. We developed EusHeidelTime for Basque time expression extraction and normalisation. For it, we analysed time expressions in Basque, we created the rules and resources for the tool and we built corpora for development and testing. We finally ran an experiment to evaluate EusHeidelTime's performance. We achieved satisfactory results in a morphologically rich language.
