Philip A. Bernstein, Adriana Szekeres, Jorgen Thelin, Sebastian Burckhardt, Sergey Bykov, Natacha Crooks, Jose M. Faleiro, Gabriel Kliot, Alok Kumbhare, Muntasir Raihan Rahman, Vivek Shah
2017 Proceedings of the ACM on Programming Languages  
We present Geo, an open-source geo-distributed actor system that improves performance by caching actor states in one or more datacenters, yet guarantees the existence of a single latest version by virtue  ...  of a distributed cache coherence protocol.  ...  A distinguishing feature of our actor-based approach is that it separates geo-distribution from durability, which is highly relevant for actor-based services: (1) Providing durability for volatile actors  ...

USING GEO-DATA CORPORATELY ON THE RESPONSE PHASE OF EMERGENCY MANAGEMENT

E. Demir Ozbek, S. Ates, A. C. Aydinoglu
2015 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
Management of the industrial fire case is organized according to defined actors, activities, and working cycle that describe required geo-data.  ...  Following developing web technologies, this scenario based approach can be effective to use geo-data on the web corporately.  ...  GII provides tools giving easy access to distributed databases for emergency management actors who need geo-data for their own decision making and emergency tasks.  ...

Actor-Oriented Database Systems

Philip A. Bernstein
2018 2018 IEEE 34th International Conference on Data Engineering (ICDE)  
We present the vision of an actor-oriented database.  ...  Its goal is to integrate database abstractions into an actor-oriented programming language for interactive, stateful, scalable, distributed applications that use cloud storage.  ...  In a multi-master setting, many updatable copies of an actor may be running. This is mainly useful for geo-distribution, with copies running in different datacenters.  ...

A SOA-Based Module for the Production of Geo-Summaries

Elena Roglia, Rosa Meo
2014 International Journal of Organizational and Collective Intelligence  
MDR, developed in the context of an overall project based on SOA architecture, adds updated information to the system via Web Services provided by OpenStreetMap and GeoNames.  ...  Furthermore, MDR can be applied for the acquisition and the integration of users' spatial annotations and use them in any way to produce, illustrate and enhance geo-summaries.  ...  The concept of Web Service implies an architectural model made of distributed objects or applications, which are located in different parts of the network and/ or different platforms.  ...

Spatio-Temporal Small Worlds for Decentralized Information Retrieval in Social Networking [article]

Georg Groh and Florian Straub and Benjamin Koster
2012 arXiv   pre-print
We discuss foundations and options for alternative, agent-based information retrieval (IR) approaches in Social Networking, especially Decentralized and Mobile Social Networking scenarios.  ...  In addition to usual semantic contexts, these approaches make use of long-term social and spatio-temporal contexts in order to satisfy conscious as well as unconscious information needs according to Human  ...  This kind of information is usually pro-actively delivered by awareness services, or news services, or by direct communication services [14] .  ...
