The next generation of Geographic Information Systems (GIS) is anticipated to automate some of the reasoning required for spatial analysis. An important step in the development of such systems is to gain a better understanding and corresponding modeling practice of when to apply arithmetic operations to quantities. The concept of extensivity plays...

Why do some neighborhoods thrive, and others do not? While the importance of the local amenity mix has been established as a key determinant of local livability, its link to urban transport infrastructure remains understudied, partially due to a lack of data. Using spatiotemporal social media data from Foursquare, we analyze the impact of metro sta...

Full-text available
Loose programming enables analysts to program with concepts instead of procedural code. Data transformations are left underspecified, leaving away procedural details and exploiting knowledge about the applicability of functions to data types. To synthesize workflows of high quality for a geo-analytical task, the semantic type system needs to reflec...

Understanding syntactic and semantic structure of geographic questions is a necessary step towards true geographic question-answering (GeoQA) machines. The empirical basis for the understanding of the capabilities expected from GeoQA systems are geographic question corpora. Available corpora in English have been mostly drawn from generic Web search...
Article
Full-text available
In geographic information systems (GIS), analysts answer questions by designing workflows that transform a certain type of data into a certain type of goal. Semantic data types help constrain the application of computational methods to those that are meaningful for such a goal. This prevents pointless computations and helps analysts design effectiv...

A most fundamental and far-reaching trait of geographic information is the distinction between extensive and intensive properties. In common understanding, originating in Physics and Chemistry, extensive properties increase with the size of their supporting objects, while intensive properties are independent of this size. It has long been recognize...
Article
Full-text available
Web data is the most prominent source of information for deciding where to go and what to do. Exploiting this source for geographic analysis, however, does not come without difficulties. First, in recent years, the amount and diversity of available Web information about urban space have exploded, and it is therefore increasingly difficult to overvi...

In everyday communication, people effortlessly translate between spatial cognitive frames of reference. For example, a tourist guide translates from a map (“the fountain is north-west of the church”) into a cognitive frame for a tourist (“the fountain in front of the church”). While different types of cognitive reference frames and their relevance...

While location-based games (LBGs) have been around for some time, only few of them have succeeded in attracting a larger number of players. One reason is the difficulty of suitable embedding of game concepts in an environment. In order to reach players from different places, LBG concepts need to be relocalized in a way which preserves the particula...
Chapter
Using cognitive linguistic strategies, people can verbally encode and convey their spatial realities with little effort (i.e. “my house is right across the street from the grocery store”). However, to date there are a limited number of ways to transform such spatial information into forms that are useful for computational analysis in a geographic i...
Conference Paper
Full-text available
Currently, systems that let people search for opportunities to fulfill their spatio-temporal needs are built according to the conceptual model of service provider and consumer: After the providers make their needs publicly available, consumers use a specifically tailored query engine to find fitting offers. E.g., in carpooling, someone wants to fil...
Article
In Geographic Information Systems (GIS), geoprocessing workflows allow analysts to organize their methods on spatial data in complex chains. We propose a method for expressing workflows as linked data, and for semi-automatically enriching them with semantics on the level of their operations and datasets. Linked workflows can be easily published on...

Full-text available
In this article, we critically examine the role of semantic technology in data driven analysis. We explain why learning from data is more than just analyzing data, including also a number of essential synthetic parts that suggest a revision of George Box’s model of data analysis in statistics. We review arguments from statistical learning under unc...
Article
The linked data Web provides a simple and flexible way of accessing information resources in a self-descriptive format. This offers a realistic chance of perforating existing data silos. However, in order to do so, space, time and other semantic concepts need to function as dimensions for effectively exploring, querying and filtering contents. Whil...
Conference Paper

Private transport accounts for a large amount of total CO2 emissions, thus significantly contributing to global warming. Tools that actively support people in engaging in a more sustainable life-style without restricting their mobility are urgently needed. How can location-aware information and communication technology (ICT) enable novel interactiv...
Article
Maintaining knowledge about the provenance of datasets, that is, about how they were obtained, is crucial for their further use. Contrary to what the overused metaphors of ‘data mining’ and ‘big data’ are implying, it is hardly possible to use data in a meaningful way if information about sources and types of conversions is discarded in the process...

Conference Paper
Wayfinding models can be helpful in describing, understanding, and technologically supporting the processes involved in navigation. However, current models either lack a high degree of formalization, or they are not holistic and perceptually grounded, which impedes their use for cognitive engineering. In this paper, we propose a novel formalism tha...

What exactly does interoperability mean in the context of information science? Which entities are supposed to interoperate, how can they interoperate, and when can we say they are interoperating? This question, crucial to assessing the benefit of semantic technology and information ontologies, has been understood so far primarily in terms of standa...
Chapter
Increasingly large amounts of data are being generated by technical sensors distributed in the human environment. However, a naked sensor value alone is meaningless. It lacks crucial meta-information, including the support and spatio-temporal resolution, and more generally the observation and interpretation process in which it is embedded. In order...
Conference Paper
This paper discusses counter-measures for cognitive biases in maps based on pragmatic communication. We argue that communicative measures can be used to either increase bias awareness or to switch the representation to a form which avoids particular biases depending on the task.
Conference Paper
We argue that current technical and legal attempts aimed at protecting Geoprivacy are insufficient. We propose a novel 2-dimensional model of privacy, which we term "civilized cyberspace". On one dimension there are engineering, social and legal tools while on the other there are different kinds of interaction with information. We argue why such a...

Reference to places is a central but largely underexposed problem of information science. Place has been a major object of research in many domains including Geography, Cognitive Science and Geographic Information Science. However, Geographic Information Systems (GIS) have been built solely on space reference systems creating a gap between human co...
Article
Place narratives provide a rich resource of learning how humans localize places. Place localization can be done in various ways, relative to other spatial referents, and relative to agents and their activities in which these referents may be involved. How can we describe places based on their spatial and semantic relationships to objects, qualities...

Geospatial semantics as a research field studies how to publish, retrieve, reuse, and integrate geo-data, how to describe geo-data by conceptual models, and how to develop formal specifications on top of data structures to reduce the risk of incompatibilities. Geo-data is highly heterogeneous and ranges from qualitative interviews and thematic maps...
Conference Paper
The concepts of scale is at the core of cartographic abstraction and mapping. It defines which geographic phenomena should be displayed, which type of geometry and map symbol to use, which measures can be taken, as well as the degree to which features need to be exaggerated or spatially displaced. In this work, we present an ontology design pattern...
