Towards Task-Based Temporal Extraction and Recognition

pdf-format:


Abstract

We seek to improve the robustness and portability of temporal
information extraction systems by incorporating data-driven
techniques. We present two sets of experiments pointing us in this
direction. The first shows that machine-learning-based
recognition of temporal expressions not only achieves high
accuracy on its own but can also improve rule-based
normalization. The second makes use of a staged
normalization architecture to experiment with machine learned
classifiers for certain disambiguation sub-tasks within the
normalization task.
