摘要:

微地图是自媒体时代地图泛化的产物。当前微地图的研究尚未关注如何将文本描述中的空间方向关系转译为地图表达的机制,制约了微地图的发展。基于此,本文提出了微地图制图的空间方向关系转译法。在图论的支持下构建了微地图的表达模型,明确了微地图的数据组织形式,定义了微地图的描述结构,借助自然语言的预训练模型从文本描述中提取空间方向关系,并将其转译为图结构的微地图进行表达,为微地图制图提供了目标框架。通过构造数据集,从定性(微地图的特征匹配性)和定量(微地图的结构稳定性,包括可读性、稳定性和平衡性)两方面验证了本文方法的可行性。试验结果表明,在选取的500个测试数据样本中,可读性在[0.772 9,0.982 1]之间浮动,均值为0.928 6;稳定性在[0.001 6,0.463 8]之间浮动,均值为0.091 2;平衡性在[0.000 016,0.062 816]之间浮动,均值为0.008 5。微地图可读性的值接近于1,稳定性和平衡性的值接近于0,且生成的地图符合微地图的特点。本文方法能够有效提取制图实体和实体间的空间方向关系,并实现路径连通、结构稳定的微地图绘制,整体表现良好。

Abstract:

We-maps are a generalized form of maps emerging in the era of social media, characterized by micro-content, low entry barriers, rapid production, and personalization. However, current research on We-maps lacks mechanisms to translate spatial directional relations from textual descriptions into cartographic expressions, which limits the development of We-map generation. In response, this paper proposes a spatial directional relation translation method for We-map making. A We-map representation model is established under the support of graph theory, defining its data organization and description structure, which serves as the target schema for the translation process. Structured spatial directional relations are extracted from natural language and stored in graph-based structures. A dual-layout strategy is designed to visualize these structures into map representations. The proposed method is validated using a custom dataset through both qualitative (feature matching of We-maps) and quantitative (structural stability of We-maps, including readability, stability, and balanced) metrics. Quantitative evaluation on 500 test samples shows that the readability scores ranged from 0.772 9 to 0.982 1, with a mean of 0.928 6. The stability values ranged from 0.001 6 to 0.463 8, with a mean of 0.091 2. The balance values ranged from 0.000 016 to 0.062 816, with a mean of 0.008 5. The readability value is close to 1, while the stability and balance metrics are close to 0, confirming consistency with We-map characteristics. These results demonstrate the method's effectiveness in extracting cartographic entities and their spatial relations, enabling the automatic generation of readable and stable We-maps with connected paths and structured layouts.
