摘要:

推断文本文档中实体提及的语义类型是许多下游NLP任务的重要资产,例如语义角色标签,实体消歧,知识库问答等。先前的工作主要集中在监督解决方案上,这些解决方案通常在相对较小到中等大小的类型系统上操作。在这项工作中,我们描述了两个系统,旨在预测以下两个任务的类型信息,即TypeSuggest模块,一个无监督的系统,旨在预测一组用户输入的查询条件的类型,和一个答案类型预测模块,它提供了一个解决方案的任务,确定正确类型的答案预期给定的查询。我们的系统推广到任何大小的任意类型系统,从而使其成为一个非常吸引人的解决方案,以任何粒度提取类型信息。

英文摘要:

Inferring semantic types for entity mentions within text documents is an important asset for many downstream NLP tasks, such as Semantic Role Labelling, Entity Disambiguation, Knowledge Base Question Answering, etc. Prior works have mostly focused on supervised solutions that generally operate on relatively small-to-medium-sized type systems. In this work, we describe two systems aimed at predicting type information for the following two tasks, namely, a TypeSuggest module, an unsupervised system designed to predict types for a set of user-entered query terms, and an Answer Type prediction module, that provides a solution for the task of determining the correct type of the answer expected to a given query. Our systems generalize to arbitrary type systems of any sizes, thereby making it a highly appealing solution to extract type information at any granularity.
