“第三届中文空间语义理解评测任务(SpaCE2023)旨在测试机器的空间语义理解能力,包括三个子任务:(1)空间信息异常识别任务;(2)空间语义角色标注任务;(3)空间场景异同判断任务。本届评测在SpaCE2022的基础上,优化了子任务一和子任务二的任务设计,并提出了子任务三这一全新的评测任务。最终有1支队伍提交参赛结果,并且在子任务一上的成绩超过了基线模型。本文还报告了大语言模型ChatGPT在SpaCE2023三个子任务上的表现,结合问题提出指令设计可改进的方向。”

It is a common practice for recent works in vision language cross-modal reasoning to adopt a binary or multi-choice classification formulation taking as input a set of source image(s) and textual query. In this work, we take a sober look at such an “unconditional” formulation in the sense that no prior knowledge is specified with respect to the source image(s). Inspired by the designs of both visual commonsense reasoning and natural language inference tasks, we propose a new task termed “Premise-based Multi-modal Reasoning” (PMR) where a textual premise is the background presumption on each source image. The PMR dataset contains 15,360 manually annotated samples which are created by a multi-phase crowd-sourcing process. With selected high-quality movie screenshots and human-curated premise templates from 6 pre-defined categories, we ask crowd-source workers to write one true hypothesis and three distractors (4 choices) given the premise and image through a cross-check procedure.
