[Abstract] [BibTeX] [PDF]

Abstract: A natural language interface will improve the human-computer interaction with Geographic Information Systems (GIS). A prerequisite for this is the mapping of natural language expressions onto spatial queries. Previous mapping approaches using, for example, fuzzy sets, failed because of the flexible and context-dependent use of spatial terms. Context changes the interpretation drastically. For example, the spatial relation ''near'' can be mapped onto distances ranging anywhere from kilometers to centimeters. We present a context-enriched semiotic triangle that allows us to distinguish between multiple interpretations. As formalization we introduce the notation of contextualized concepts that is tied to one context. One concept inherits multiple contextualized concepts such that multiple interpretations can be distinguished. The interpretation for one contextualized concept corresponds to the intention of the spatial term, and is used as input for a spatial query. To demonstrate our computational model, a next generation GIS is envisioned that maps the spatial relation ''near'' to spatial queries differently according to the influencing context.

[Abstract] [BibTeX] [PDF]

Abstract: Different forms of spatial descriptions are used to communicate information in the context of navigation in urban environments. When generated by computers, such descriptions are combinations of map features in a predefined way. Unlike computers, however, people are capable of flexibly generating navigational spatial descriptions by taking into account a wide array of different contextual factors, e.g. a user's prior knowledge and the structure of the environment. This paper deploys the notion of pragmatics to compare formal addresses, route descriptions (generated either by computers or humans), and destination descriptions in terms of their adaptability to contextual factors in order to identify the means to creating more cognitively sound information systems.

Abstract: Comparative literature investigates texts simultaneously in multiple languages. It is by definition conducting corpus-based research (each study is based on a quantitatively discernible number of texts chosen by single sets of qualities), in practice however it is facing diverse limitations which restrict the value of generalized statements. We propose to extend well approved methods of corpus-based research to computational comparative literature in order to overcome those limitations. The core is the construction of a large corpus of annotated literary texts with a related set of computational analysis methods. The aspects of the proposed technical solution make it even suited for the comparison of multi-lingual text corpora, as the same methods can be applied to all texts irrespective of language. Computational comparative literature has a supportive function for established approaches in comparative literature. It allows for systematic evaluation of a large number of texts that goes beyond established questions.

Abstract: Data is spatial if it contains references to space. We can easily detect explicit references, for example coordinates, but we cannot detect whether data implicitly contains references to space, and whether it has properties of spatial data, if additional semantic information is missing. In this paper, we propose a graph model that meets typical properties of spatial data. we can, by the comparison of a graph representation of a ata set to the graph model, decide whether the data set (implicitly or explicitly) has these typical properties of spatial data.

We propose to use a semantic model and anbr>extraction methodology which is aimed at allowing the consumption ofbr>geographic information in an intuitive way. We illustrate our approachbr>based on previous work of a highway navigation conceptualization andbr>present a functional approach to exploit granularity extractions targetedbr>at enabling the user to change the point of view in navigation tasks.

Abstract: The location check-in data, developing along with social network, are considered as user-generated crowd-sourcing geospatial data. With massive data volume, abundance in contained information, and high up-to-date status, the check-in data provide a new data source for geographic information service represented by location-based service. However, there is a significant quality issue regarding to crowd-sourcing data, which has a direct influence to data availability. In this paper, a data quality analysis approach is designed for the location check-in data and a check-in data uncertainty model is proposed. First of all, the quality issue of location check-in data is discussed. Then, according to the characteristics of check-in data, a location check-in data quality analysis and data processing approach is proposed, using certain standard dataset as reference to conduct an affine transformation for the check-in dataset, during which the RANSAC algorithm is adopted for outlier elimination. Subsequently, combining GIS data uncertainty theory, an uncertainty model of processed check-in data is set up. At last, using location check-in data obtained from jiepang.com as experimental data and selected navigation data as data standard, multiple location check-in data quality analysis and uncertainty modeling experiments are conducted. By comprehensive analysis of experimental results, the feasibility of proposed location checkin data quality analysis and process approach and the availability of proposed uncertainty model are verified. The novel approach is proved to have a certain practical significance to the study of the quality issue of crowd-sourcing geographic data.

[Abstract] [BibTeX]

Abstract: Space and time are the most prominent features of our everyday experience. While we can movebr>relatively freely within and interact with space, time imposes stricter restrictions on us. We arebr>mere bystanders to the ever-changing flow of time. Close observation of our environment revealsbr>that nothing stands still and everything changes constantly.br>It is generally acknowledged that GIS need to account for the dynamic aspects of the world.br>The almost exclusive depiction of static phenomena (spatial configurations) in GIS reveals itsbr>close historical ties to Cartography. A first call to move beyond the ''map metaphor'' and focusbr>on ''spatial processes, changing the spatial configuration'' can be found in Abler et al. (1971). Anbr>integration of processes in GIS will help to answer questions related to ''When somethingbr>happened or will happen'' (Frank 1998). For a thorough review focusing on the dynamic aspectsbr>in GIS research see Worboys (2005). The vision of a fully dynamic GIS requires a simple,br>combinable, and scalable formal application-independent approach (Weiser and Frank 2010).br>In this work we present our ongoing research on (1) how to represent processes over multiplebr>levels of detail, (2) their combination, and as a result (3) reasoning over processes. We buildbr>upon the notion of ''processes over multiple levels of detail (LoD)'' we have formalizedbr>previously, using partial function application (Weiser and Frank 2012). We now focus on thebr>challenges that arise from combining those processes.

[Abstract] [BibTeX] [PDF]

Abstract: Personal Information Management is the study of how people store andbr>retrieve data for their purposes. Traditionally the data is stored in applications like calendars, todo-lists, address books, etc... These applications or PIM-tools do not take the spatial character of much of the information into account. But space, just as time plays a major role in the way we organize and utilize personal information.br>In this paper we present ongoing research in which we try to identify a proper formalism for integrating space into PIM-tools. We therefore attempt to model an ordinary task from daily life experience and expect to find answers to the question of how and what to integrate into a system to move from a regular PIM-tool to a spatial-PIM.

[Abstract] [BibTeX] [PDF]

Abstract: Traditionally personal information management (PIMs) tools supportbr>people in their daily tasks. While research around personal information management focuses on how to store and retrieve information e ciently,we focus on the use of spatial (geographic) aspects in personal information. Tasks and appointments are represented in calendars or todolists,br>often including temporal and sometimes even spatial information. Un-br>fortunately the spatial information is seldom used for task planning or execution support. Therefore current PIM applications, e.g. on mobile phones, do not use the full power of the devices, and they too often simply resemble a piece of paper with the relevant information on it. The research goal is to extend the possibilities of modern GIS and enable ubiquitous GPS technology to pro-actively support the user in his daily tasks.

[Abstract] [BibTeX] [PDF]

Abstract: 3D and temporal objects must be included in GIS to handle real
world phenomena. Many have studied extension of spatial operations to these
multi-dimensional spaces and suggested technical solutions to extend a spatial
operation to a new multi-dimensional space. These technical approaches have
led to developments which can not be generalized. One technique used to
extend a spatial operation from 2D to a multi-dimensional space is not likely
usable for another spatial operation, nor to extend the same spatial operation to
another multi-dimensional space. This paper suggested studying spatial
operations via their dimension-independent properties. It intends to construct a
mathematical framework to integrate spatial operations of different multi-
dimensional spaces (3D and time) a GIS should support. The framework will be
independent of the space in which the operations are applied using algebraic
structures - and more specifically category theory - that ignore those properties
of operations which depend on the objects they are applied to. Implementations
for some case studies for spatial operations of moving points are presented.
