Abstract

Temporal information is crucial in knowledge extraction. Being able to locate events in a timeline is necessary to understand the narrative behind every text. To this aim, several temporal taggers have been proposed in literature -nevertheless, not all languages received the same attention. Most taggers work only for English texts, and not many have been developed for other languages. Also the scarcity of annotated corpora in other languages notably hinders the task. In this paper we present a new rule-based tagger called Annotador (Anotador in Spanish) able to process texts both in Spanish and English. Furthermore, a new corpus with more than 300 short texts containing common temporal expressions, called the HourGlass corpus, has been built in order to test it and to facilitate the development of new resources and tools. Professionals from different domains intervened in the gathering of the text, making it heterogeneous and easy to use thanks to the tags added to each entry. Finally, we analyzed main challenges in the time expression extraction task.

Project objectives

La aportación persigue los siguientes objetivos: desarrollar un etiquetador temporal basado en reglas capaz de procesar textos en español e inglés; construir un nuevo corpus denominado HourGlass con más de 300 textos cortos que contienen expresiones temporales comunes; facilitar el desarrollo de recursos y herramientas mediante la creación de un corpus heterogéneo y anotado por profesionales de distintos ámbitos; analizar los principales desafíos en la tarea de extracción de expresiones temporales; y contribuir a superar la escasez de corpus anotados en idiomas distintos al inglés.
[+]

Most relevant results

Los resultados más relevantes de esta aportación se centran en el desarrollo y evaluación de una herramienta para el etiquetado temporal en textos en español e inglés. En primer lugar, se presenta Annotador, un etiquetador basado en reglas capaz de procesar ambos idiomas. En segundo lugar, se ha construido el corpus HourGlass, compuesto por más de 300 textos breves con expresiones temporales comunes, diseñado para evaluar el etiquetador y fomentar la creación de recursos similares. En tercer lugar, la heterogeneidad del corpus se asegura mediante la participación de profesionales de diversos ámbitos y la inclusión de etiquetas detalladas en cada texto. Finalmente, se identifican y analizan los principales desafíos en la extracción de expresiones temporales.
