| 英文摘要 | Temporal Expression Recognition (TER) was proven to help natural language tasks like information extraction and question answering to obtain a higher performance. In this paper, we present a method for extraction of temporal expression from Uyghur text based on machine learning technique – conditional random field (CRF). A CRF classifier is trained with human annotated data, and different feature sets are combined and used in order to achieve the best performance on this task. Experimental results show that the best performing model gave an F1-Measure of 82.71 when all features are fully integrated. We also show the effect of word stemming on the performance. After word stemming, the results obtained improve to F1-Measure of 83.19. |
