摘要
青年群体热衷于在网络平台以打卡的形式记录和分享生活,打卡地成为其出行游玩的热门目的地之一。用户所发布的对于打卡地的主观体验和感受,从群体层面上通过网络空间进行了重现、反复和聚集,进而改变打卡地的固有功能属性。本文以北京市六环内为研究区,对小红书中相关打卡地文章数据通过句向量表示与聚类,多层级关键词提取等方法得到打卡地的活动语义。在此基础上,通过丰富度及空间聚类方法分析打卡地功能-活动语义之间的转换及其空间分布特征。结果表明,打卡地的活动语义相较于功能语义更加复杂多样且体现人本视角。功能-活动语义的转换可总结为组合类、一致类和衍生类,语义转换特点与区域功能紧密相关,体现在历史文化融入、商业综合体互转和满足多元化需求等方面,进而空间分布呈现出聚集性和区域性。
The youth group is passionate about documenting and sharing their life on social media platforms,making geo-tagged places one of the popular destinations for their outings and travels.The subjective experiences and feelings shared by users about geo-tagged places have been replicated and aggregated through the online space at the group level,affecting the functional attributes of these places.This study focuses on the area within the Sixth Ring Road of Beijing,using methods such as sentence vector representation,clustering,and multi-layer keyword extraction to obtain the activity semantics of the geo-tagged places.Based on this,the transformation between the functional and activity semantics of the geo-tagged places and their spatial distribution characteristics were analyzed using the diversity index and spatial clustering method.The results indicate that the activity semantics of geo-tagged places are more complex and diverse compared to functional semantics,reflecting a more human-centered perspective.The transformation between functional and activity semantics can be summarized as Combined,Consistent,and Derived.The characteristics of semantic transformation are closely related to regional functions,manifested in aspects such as the integration of historical culture,the mutual transformation of commercial complexes,and the meeting of diverse needs,thereby presenting a spatial distribution with clustering and regional characteristics.
