摘要:

我们提出并比较了各种句子选择策略的主动学习的任务,检测提到的实体。最佳策略采用在数据的不同视图上训练的两个统计分类器的置信度之和。我们的实验结果表明,与随机选择策略相比,该策略减少了超过50%的所需标记的训练数据,而达到相同的性能。当仅考虑命名提及时,效果甚至更显著:系统仅使用随机选择策略所需的训练数据的42%来实现相同的性能。

英文摘要:

We propose and compare various sentence selection strategies for active learning for the task of detecting mentions of entities. The best strategy employs the sum of confidences of two statistical classifiers trained on different views of the data. Our experimental results show that, compared to the random selection strategy, this strategy reduces the amount of required labeled training data by over 50% while achieving the same performance. The effect is even more significant when only named mentions are considered: the system achieves the same performance by using only 42% of the training data required by the random selection strategy.
