视觉场景的扎根语义合成

Grounded Semantic Composition for Visual Scenes

MIT Media Laboratory(麻省理工学院媒体实验室)

P. Gorniak, D. Roy

摘要:

我们提出了一个视觉接地语言理解模型的基础上,人们如何口头描述场景中的对象的研究。该模型的重点是对单个词的意义的组合,以产生复杂的指称表达的意义。该模型已经实现,它能够理解广泛的空间指称表达。我们描述了我们的实现词级视觉接地语义和他们的嵌入在一个组成分析框架。所实现的系统选择正确的引用,以响应自然语言表达式的测试用例的很大比例。在系统的成功和失败的分析,我们揭示了视觉环境如何影响话语的语义,并提出未来的扩展模型,考虑到这种情况。

英文摘要:

We present a visually-grounded language understanding model based on a study of how people verbally describe objects in scenes. The emphasis of the model is on the combination of individual word meanings to produce meanings for complex referring expressions. The model has been implemented, and it is able to understand a broad range of spatial referring expressions. We describe our implementation of word level visually-grounded semantics and their embedding in a compositional parsing framework. The implemented system selects the correct referents in response to natural language expressions for a large percentage of test cases. In an analysis of the system's successes and failures we reveal how visual context influences the semantics of utterances and propose future extensions to the model that take such context into account.
