Full text available: PDFPDF
Focus on movement data has increased as a consequence of the larger availability of such data due to current GPS, GSM, RFID, and sensors techniques. In parallel, interest in movement has shifted from raw movement data analysis to more application-oriented ways of analyzing segments of movement suitable for the specific ...

With the large-scale adoption of GPS equipped mobile sensing devices, positional data generated by moving objects (e.g., vehicles, people, animals) are being easily collected. Such data are typically modeled as streams of spatio-temporal (x,y,t) points, called trajectories . In recent years trajectory management research has progressed significantly towards efficient storage ...

Mobility data is becoming an important player in many application domains. Many techniques have been elaborated to extract statistical knowledge from the data sets gathering raw data tracks about the moving objects of interest to an application. These data tracks obey the physical-level specifications of the devices used for data ...

Full text available: PDFPDF
GPS devices allow recording the movement track of the moving object they are attached to. This data typically consists of a stream of spatio-temporal (x,y,t) points. For application purposes the stream is transformed into finite subsequences called trajectories . Existing knowledge extraction algorithms defined for trajectories mainly assume a specific ...

Full text available: PDFPDF
With the prevalence of GPS-embedded mobile devices, enormous amounts of mobility data are being collected in the form of trajectory - a stream of (x,y,t) points. Such trajectories are of heterogeneous entities - vehicles, people, animals, parcels etc. Most applications primarily analyze raw trajectory data and extract geometric patterns. Real-life ...

A major obstacle to the development of ontologies in support of the Semantic Web is the poor capability of current ontology techniques to handle very large ontologies, in particular regarding scalability of reasoners. This paper builds on the assumption that very large ontologies can be efficiently handled using database management ...

Spatio-temporal data management has progressed significantly towards efficient storage and indexing of mobility data. Typically such mobility data analytics is assumed to follow the model of a stream of (x,y,t) points, usually coming from GPS-enabled mobile devices. With large-scale adoption of GPS-driven systems in several application sectors (shipment tracking to ...

This book constitutes a collection of research achievements mature enough to provide a firm and reliable basis on modular ontologies. It gives the reader a detailed analysis of the state of the art of the research area and discusses the recent concepts, theories and techniques for knowledge modularization. The 13 ...

May 2009 Modular Ontologies: Concepts, Theories and Techniques for Knowledge Modularization
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 0

Modularization can be sought for as a technique to provide context-dependent perspectives over a given shared information repository. This chapter presents an approach to database modularization where the modules represent application-specific perspectives over the shared database. The approach is meant to support the creation/definition of the modules as part of ...

In an ideal world, ontologies would be build in a modular way from the start thus showing the benefits well known from modularization in software engineering. The first part of this book contained an example of how this can be done for databases. Unfortunately, the field of ontology engineering has ...

Another valid view on modularity is ontologies that differs from the one taken in part II of the book is the idea that modules are not created by splitting up a large ontology into smaller parts but by composing a number of small ontologies that have been created independently of ...

This part is meant to convey a general introduction to the domain of knowledge modularization. Chapter 1 overviews the issues and the proposed solutions that are relevant to ontology modularization. This chapter is deliberately informal to be accessible to the largest audience, so that readers can quickly get familiar with ...

Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 6

Modularization is a familiar concept in IT, widely used in e.g. software development. It has been somehow neglected in knowledge management. Database research has only marginally addressed the topic, mainly for the development of cooperative database systems. Instead, research on ontologies, seen as the knowledge provider for the semantic web, ...

Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitoring). Current DBMS support for such data is limited to the ability to store and ...

There is great potential for the development of many new applications using data on mobile objects and mobile regions. To promote these kinds of applications advanced data management techniques for the representation and analysis of mobility-related data are needed. Together with application experts (behavioural ecologists), we investigate how two novel ...

This paper presents a semantic foundation of temporal conceptual models used to design temporal information systems. We consider a modelling language able to express both timestamping and evolution constraints. We conduct a deeper investigation of evolution constraints, eventually devising a model-theoretic semantics for a full-fledged model with both timestamping and ...

Citation Count: 3

Worldwide globalization increases the complexity of problem solving and decision-making, whatever the endeavor is. This calls for a more accurate and complete understanding of underlying data, processes and events. Data representations have to be as accurate as possible, spanning from the current status of affairs to its past and future ...

Successful information management implies the ability to design accurate representations of the real world of interest, in spite of the diversity of perceptions from the applications sharing the same database. Current database management systems do not provide representation schemes that preserve each perception while fully supporting their diversity and maintaining ...
