语义分析 semantic parsing 其中语义分析是指将自然语言句子转化为反映这个句子语义的形式化表达。例如 我吃了一块肉 一块肉被我吃了 在语义上都表示为吃(我,肉)的意思,但句子结构却有不同。 句子的语义分析是对句子处理技术更高一级的要求,在信息检索、信息抽取、自动文摘等应用广泛。 1. SRL定义 Semantic Rol...

语义分析的高级阶段，语义角色标注（SRL）技术，以其谓词-论元结构分析见长，适用于信息检索、信息抽取、自动文摘等应用场景。SRL核心任务是识别句子中谓词及其对应的语义角色，例如“我吃肉”中的“我”是执行者，“肉”是受事。英文领域有成熟SRL数据集，而中文数据集相对较少，其中Chinese Proposition Ban...
3.1.6Semantic labelling While all the aforementioned feature types are directly extracted from input images, a higher level of features can be generated in the form of semantic labelling maps by making use ofclassification algorithms(noted assemantic labelsin the table, seeFig. 5e). These maps ca...

In this paper, we present a method for performing accurate and robust six degrees-of-freedom camera pose estimation based only on the pixelwise semantic labelling of a single query image. Localization is performed using a sparse 3D model consisting of semantically labelled points and curves, and ...
Overall, our weak supervision approach reaches ∼95% of the quality of the fully supervised model, both for semantic labelling and instance segmentation. 语义标记和实例分割是需要特别昂贵的注释的两项任务。 从边界框检测注释形式的弱监督开始,我们提出了一种不需要修改分割训练程序的新方法。 我们表明,...
