Happy New Year

Posted: 1. January, 2012 in Uncategorized

I wish you all health, happiness and luck in the new year!

My first time at Pervasive Computing and Communications. My impressions are that topics covered were mostly:

  • Context modeling and reasoning
  • Activity recognition with smartphones and wearable sensors
  • Localization

The workshops provided more diverse topics from pervasive computing.

Some papers I found intersting:

  • Reduce Latency: The Key to Successful Interactive Remote Rendering Systems
    Shu Shi
  • PocketSocial: Your Distributed Social Context Now in Your Pocket
    Bo Xing, Kristoffer Gronowski, Nimish Radia, Martin Svensson and Andrew Ton
    Ericsson Research. San Jose, USA
  • Embracing the Cloud for Better Cyber Security
    Craig A. Shue and Brent Lagesse
    Cyberspace Science and Information Intelligence Research
    Computational Sciences and Engineering
    Oak Ridge National Laboratory
  • An Augmented Reality Based Group Communication System for Bikers Using Smart Phones
    Lien-Wu Chen, Yu-Hao Peng, and Yu-Chee Tseng
    Department of Computer Science, National Chiao-Tung University, Taiwan
  • Implementing Powerful Web Services for Highly Resource-Constrained Devices
    Christian Lerche, Nico Laum, Guido Moritz, Elmar Zeeb, Frank Golatowski, Dirk Timmermann
    Institute of Applied Microelectronics and Computer Engineering
    University of Rostock, Germany
  • Video Entity Resolution: Applying ER Techniques
    for Smart Video Surveillance
    Liyan Zhang Ronen Vaisenberg Sharad Mehrotra Dmitri V. Kalashnikov
    Department of Computer Science
    University of California, Irvine

In short, conference program be shoud extended for more complete systems, and not just improvment of existing methods in different domains. Anyway the conference was excellent place to meet world-class researchers woring in the field of pervasive computing. I had great time :)

Here is a short summary to our 1st PerCom PerCoSC workshop.

First of all, we are proud that our workshop was well received at the conference. Many participants (20 – 35 people varying from sessions) were present with interesting talks. The talks covered complementary facets of the workshop’s main topics, i.e. pervasive cloud and community computing. For several papers more than one authors came. We got interactive discussions after each papers and in the last discussion session.

The topics covered during the talks include:

  • Software engineering
    • Architecture patterns
    • Offline work mechanism
    • Decision models
  • Security and privacy
    • Data encryption, operations on encrypted data
    • Code signatures
  • Cloud services extension of pervasive/ubiquitous computing – ubiquitous/pervasive cloud
    • Computation intensive services (parallel proc., search, huge dataset query)
    • Data management services
    • Network services
  • SOA
    • Service resource management, service discovery, composition
  • Cyber Foraging combined with clouds
    • Lower latency

There were aslo discussed several use cases:

  • Service technicians
  • Cloud computing operating systems (Cloud OS)
  • Mobile desktop search
  • Indoor/outdoor positioning (smart home)
  • Content Recommendation and Adaptation
  • Mobile Augmented Reality
  • Home Automation and Security

The participants had an intersting discussion trying to brainstorm on the following questions:

  • What are the requirements of pervasive communities?
  • How will cloud computing benefit pervasive communities?
  • What are the challenges for pervasive service clouds?

Based on the submissions this year, a more clear focus will be set to the new proposal for the next year. We are planning to organize PerCoSC 2012 within PerCom 2012, which will be held in Lugano, Switzerland.

The First IEEE PerCom Workshop on
Pervasive Communities and Service Clouds (PerCoSC 2011)

Held in conjunction with
9th Annual IEEE International Conference on
Pervasive Computing and Communications 2011 (PerCom 2011),

March 21, 2011, Seattle, USA

The First IEEE PerCom Workshop on Pervasive Communities and Service Clouds aims to offer researchers, Ph.D. students, and practitioners a forum to present and discuss research advances and challenges related to cloud computing support for pervasive communities. The workshop thus aims to enable the sharing of insights and experiences related to the development and use of cloud computing technologies, often called service clouds, for supporting pervasive communities. Pervasive communities are user communities that are enabled by pervasive computing technologies. Service clouds denote the totality of cloud computing services, applications, platforms, and infrastructure that comply with the service-oriented architecture paradigm.
Pervasive community services deal with data sensed and collected from the users’ physical environments via networked mobile devices. Hence, they support data exchange, communication, and collaboration among mobile users. Pervasive communities of users with mobile devices and network connections have been increasing. Thus, the pervasive technologies to support pervasive communities face new requirements, e.g., related to mobility support, context-awareness, spatiotemporal intelligence, connectivity to communities, information sharing, collaboration, pervasive interaction, and privacy and security issues. However, the computational capabilities of mobile devices remain limited, when faced with pervasive communities who share large data volumes. Cloud computing technologies offer computational resources on a pay-per-use basis and are capable of abstracting technical details from the mobile devices. These technologies thus hold the potential for enabling pervasive community services with varying computing requirements in a cost-effective and scalable manner. Indeed, service clouds may envision future pervasive computing and enables innovative pervasive community services and applications.

Topics

Topics of interest include but are not restricted to the following topics:
* cloud computing (services, platforms, infrastructure, and standards etc.) for pervasive communities

* software architectures for cloud computing and pervasive computing
* data modeling and management for cloud computing and pervasive communities
* social software and Web 2.0 in cloud computing and pervasive computing
* augmented reality for pervasive communities

7th IEEE Workshop on Context Modeling and Reasoning (CoMoRea) at the 8th IEEE PerCom

Shared via AddThis

Important dates:

General Information:
Ontology-based systems have been developed to structure content and support knowledge retrieval and management. Semantic multimedia data processing and indexing in ontology- based systems is usually done in several steps, one starts by enriching multimedia metadata with additional semantic information (possibly obtained by methods for bridging the semantic gap). Then, in order to structure data, a localized and domain specific ontology becomes necessary since the data has to be interpreted domain-specific. The annotations are stored in an ontology management system where they are kept for further processing. In this scope, Semantic Database Technologies are now applied to ensure reliable and secure access, efficient search, and effective storage and distribution for both multimedia metadata and data. Their services can be used to adapt multimedia to a given context based on multimedia metadata or even ontology information. Services automate cumbersome multimedia processing steps and enable ubiquitous intelligent adaptation. Both, database and automation support facilitate to ubiquitous use of multimedia in advanced applications.

We are searching for research contributions on the mapping and integration of multimedia metadata and ontologies into databases, on multimedia query languages, on the optimization and processing of semantic queries. Moreover, we are interested how multimedia data services are conceived to ensure interoperability, how to improve security and reliability of access and storage of multimedia data and metadata.

In addition, application papers showing concrete semantic multimedia database services (like, adaptation of multimedia, semantic enrichment of multimedia, and bridging of media breaks), as well as demonstrations on database technologies (like, mobile online image analysis and retrieval) are expected.

Topics of interest:

  • Multimedia metadata models and mappings to databases
  • Multimedia ontology and interoperability
  • Multimedia ontology to database mapping and processing
  • Multimedia query optimization and processing
  • Ontology query languages and multimedia
  • Semantic retrieval in multimedia databases
  • Database management: security, indexing, reliability, distribution, transactions
  • Indexing strategies for multimedia databases
  • Semantic enrichment and annotation of multimedia
  • Semantic metadata management
  • Uncertainty in multimedia databases
  • Human-computer interfaces for multimedia database access
  • Mobile multimedia database services
  • Context-aware multimedia
  • Semantic adaptation of multimedia
  • Proactive semantic multimedia delivery & distribution services
  • Self-organization in service oriented multimedia architectures
  • Semantic multimedia demonstrations and applications

WORKSHOP ON CONTEXT-AWARE RECOMMENDER SYSTEMS (CARS-2009)

New York, NY, USA, October 25, 2009

http://ids.csom.umn.edu/faculty/gedas/cars2009/

(In conjunction with the 3rd ACM Conference on Recommender Systems)

CALL FOR PAPERS

The importance of contextual information has been recognized by researchers and practitioners in many disciplines, including e-commerce personalization, information retrieval, ubiquitous and mobile computing, data mining, marketing, and management.  While a substantial amount of research has already been performed in the area of recommender systems, the vast majority of existing approaches focuses on recommending the most relevant items to users and does not take into account any additional contextual information, such as time, location, weather, or the company of other people.  Therefore, this workshop aims to bring together researchers with wide-ranging backgrounds to identify important research questions, to exchange ideas from different research disciplines, and, more generally, to facilitate discussion and innovation in the area of context-aware recommender systems (CARS).  In particular, topics of interest for this workshop include (but are not limited to):

– Context modeling techniques for recommender systems;

– Context-aware user modeling for recommender systems;

– Data sets for context-dependent recommendations;

– Algorithms for detecting the relevance of contextual data;

– Algorithms for incorporating contextual information into recommendation process;

– Algorithms for building explicit dependencies between contextual features and ratings;

– Interacting with context-aware recommender systems;

– Novel applications for context-aware recommender systems;

– Large-scale context-aware recommender systems;

– Evaluation of context-aware recommender systems.

In case the main topic of the paper is a challenging dataset for context-aware recommender systems, the author(s) should describe the data model and the main features of this dataset, and make the dataset available for the research community.

Paper submission.  The length of submissions is 5 pages in the standard ACM SIG proceedings format.  Microsoft Word and LaTeX templates for papers in ACM SIG format are provided at:

http://www.acm.org/sigs/publications/proceedings-templates

All submissions must be in English and the files should be in PDF format.

Paper submissions and reviews will be handled electronically; each paper will be evaluated by the workshop program committee based on originality, significance, technical soundness, and clarity.  All papers must be submitted through the CARS-2009 page on the EasyChair conference management site at:

http://www.easychair.org/conferences/?conf=cars2009

Accepted papers.  The accepted papers will be made available on the workshop website, and their authors will present their work in front of the workshop audience.  The workshop will NOT request the copyright transfer from the authors; therefore, after receiving feedback at the workshop, the authors will be able to submit the improved versions of their papers to conferences and journals (the workshop organizers are currently exploring the possibilities to organize a special issue on this topic in some research journal).

Note about workshop participation.  According to RecSys-2009 procedures, only accepted workshop participants can register to attend the workshops.  Those, who do not have a paper at the CARS-2009 workshop but would still like to attend it, are encouraged to email a statement of interest (no more than 1

page) to the workshop chairs by August 10.  The requests to participate will be honored based on the space available.

2009 International Workshop on Location Based Social Networks (LBSN’09)
http://research.microsoft.com/en-us/um/people/xingx/LBSN2009.htm

Nov. 3, 2009, Seattle, WA, USA
Held in conjunction with the 17th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems

Aim and Scope
Social networking services have become extremely popular in recent years, especially for young people. However, they are still rooted in the virtual world. People usually need to sit behind a desktop computer to upload photos, write blogs and communicate with friends. The development of wireless networks and location sensing technologies have made it easier to track and share personal location information on the fly. By adding a location dimension, we can bring social networking back from the virtual world into real life and allow real-life experiences to be shared in a more convenient way. We define Location Based Social Networks (LBSN) as social network services where people can track and share location related information with each other, via either mobile or desktop computers. As location is one of the most important aspects for peoples everyday lives, a lot of novel application scenarios can be supported by LBSN. For example, we
can collect and share more trustworthy location recommendations within LBSN and use them to rank interesting locations, discover new places, people and activities.
The objective of this workshop is to provide a single forum for researchers and technologists to discuss the state-of-the-art, present their contributions, and set future directions in emerging innovative research for location based social networks.

Topics of Interest
Topics of interest include, but are not limited to the following aspects of location based social networks:
* Spatial data mining and knowledge discovery
* Personal location/trajectory data mining
* Spatial query log mining
* Geo-tagged multimedia mining
* Opinion mining for location related information
* Spatial data indexing
* Hybrid index for spatial, textual and multimedia data
* Index for moving objects
* Location based social network analysis
* Geographical information extraction and retrieval
* Spatial data acquisition and pre-processing
* Spatial data visualization and computer human interface
* Location privacy, data sharing and security
* Navigation and traffic prediction
* Systems, architectures and middleware

Submission
We seek three kinds of submissions related to location based social networks:
* Full research papers V up to 8 pages
* Vision papers and short technical papers – up to 4 pages
* Demo papers V up to 2 pages
Authors are invited to submit full, original, unpublished research papers that are not being considered for publication in any other forum. Manuscripts should be submitted in PDF format and formatted using the ACM camera ready templates available at:
