摘要

在本文中，我们提出了一个整合术语依赖关系的模型。与以往的研究不同，每对术语根据其对IR的效用分配了不同的依赖权重。实验表明，我们的模型可以显著优于以前使用固定权重的依赖模型。

Using various term dependencies according to their utilities

In this paper, we propose a model to integrate term dependencies. Different from previous studies, each pair of terms is assigned a different weight of dependency according to their utility to IR. The experiments show that our model can significantly outperform the previous dependency models using fixed weights.
