We propose and study a novel supervised approach to learning statistical
semantic relatedness models from subjectively annotated training examples. The
proposed semantic model consists of parameterized co-occurrence statistics
associated with textual units of a large background knowledge corpus. We
present an efficient algorithm for learning such semantic models from a
training sample of relatedness preferences. Our method is corpus independent
and can essentially rely on any sufficiently large (unstructured) collection of
coherent texts. Moreover, the approach facilitates the fitting of semantic
models for specific users or groups of users. We present the results of
extensive range of experiments from small to large scale, indicating that the
proposed method is effective and competitive with the state-of-the-art.

本文提出了一种基于主观注释的新型监督学习方法来学习统计句子相关性模型，该模型由大规模背景知识语料库中的文本单位关联的参数化共现统计信息组成，并提出了一种高效的算法来从相关性偏好的训练样本中学习语义模型，方法独立于语料库、适用于任何足够大的（非结构化）文本集合，并且可以为特定用户或用户组拟合语义模型。通过广泛的小到大规模实验结果表明，这种方法是有效的，竞争力强。
