“…Qualitative Spatial Reasoners (QSR), in turn, provide the means to answer more complex questions based on the description of external, that is, relational, qualities of places (cf. 'Place graphs'; Chen et al, 2018aChen et al, , 2018bHamzei et al, 2018;Kim et al, 2015Kim et al, , 2017aKim et al, , 2017bKremer, 2018). However, they focus on spatial qualities and have to deal with high computational complexity (cf., e.g., Fogliaroni, 2013).…”

Place can hardly be formally captured at the moment, as it is unclear how to represent places and draw conclusions by technological means. GIScience scholars hence use the term ‘Place’ even when they presume a paradigm similar to the one assumed for Geometrical Space, largely ignoring the richness of the geographical Place concept. This article reviews the ongoing debate and outlines directions of how to extend it much beyond the currently assumed spatial paradigm. The agenda laid out in this article aims to set a frame of reference for and stimulate future developments towards a Platial Information Science.

“…Wang et al [66] propose a toponym recognition approach based on a deep belief network as a promising and powerful method to extract georeferenced information from text. Chen et al [67] propose a place graph model for modelling spatial, non-spatial, and contextual knowledge from place descriptions. The model extends a prior place graph through georeferencing, reasoning, and querying.…”

Around the globe, Geographic Information Systems (GISs) are well established in the daily workflow of authorities, businesses and non-profit organisations. GIS can effectively handle spatial entities and offer sophisticated analysis and modelling functions to deal with space. Only a small fraction of the literature in Geographic Information Science—or GIScience in short—has advanced the development of place, addressing entities with an ambiguous boundary and relying more on the human or social attributes of a location rather than on crisp geographic boundaries. While the GIScience developments support the establishment of the digital humanities, GISs were never designed to handle subjective or vague data. We, an international group of authors, juxtapose place and space in English language and in several other languages and discuss potential consequences for Geoinformatics and GIScience. In particular, we address the question of whether linguistic and cultural settings play a role in the perception of place. We report on some facts revealed by this multi-language and multi-cultural dialogue, and what particular aspects of place we were able to discern regarding the few languages addressed.

“…Place descriptions in sources such as news articles, local chronicles, social media texts, and travel diaries represent a method of communicating spatial information and a type of mental representation of human spatial cognition [24,25]. By exploring human mobility and activities via place descriptions, we can extract abundant semantic information of places [26,27].…”

Geospatial Semantics Analysis of the Qinghai–Tibetan Plateau Based on Microblog Short Texts

Place descriptions record qualitative information related to places and their spatial relationships; thus, the geospatial semantics of a place can be extracted from place descriptions. In this study, geotagged microblog short texts recorded in 2017 from the Tibetan Autonomous Region and Qinghai Province were used to extract the place semantics of the Qinghai–Tibetan Plateau (QTP). ERNIE, a language representation model enhanced by knowledge, was employed to extract thematic topics from the microblog short texts, which were then geolocated and used to analyze the place semantics of the QTP. Considering the large number of microblogs published by tourists in both Qinghai and Tibet, we separated the texts into four datasets according to the user, i.e., local users in Tibet, tourists in Tibet, local users in Qinghai, and tourists in Qinghai, to explore the place semantics of the QTP from different perspectives. The results revealed clear spatial variability in the thematic topics. Tibet is characterized by travel- and scenery-related language, whereas Qinghai is characterized by emotion, work, and beauty salon-related language. The human cognition of place semantics differs between local residents and tourists, and with a greater difference between the two in Tibet than in Qinghai. Weibo texts also indicate that local residents and tourists are concerned with different aspects of the same thematic topics. The cities on the QTP can be classified into three groups according to their geospatial semantic components, i.e., tourism-focused, life-focused, and religion-focused cities.
