A new perspective on "community" and its implications for computer-mediated communication systems

Amy Bruckman
2006 CHI '06 extended abstracts on Human factors in computing systems - CHI EA '06  
This paper argues that a new perspective on the concept "community" can shed light on the subject. Ideas from cognitive science, particularly category theory, can help.  ...  I will argue that these theoretical insights can help resolve debates about the nature of community, and also can help guide designers of computer-mediated communication (CMC) systems.  ...  Acknowledgments Barry Wellman and Nancy Nersessian provided invaluable help. Special thanks to Jason Elliott, Andrea Forte, Jim Hudson, and José Zagal.  ...

A rate-disortion perspective on local differential privacy

Anand D. Sarwate, Lalitha Sankar
2014 2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton)  
We model utility by a distortion measure and consider privacy mechanisms that act via a memoryless channnel operating on the data.  ...  We show that under Hamming distortions, the differential privacy risk is lower bounded for all nontrivial distortions, and that the lower bound grows logarithmically in the alphabet size.  ...  For a probability distribution P (x) on a space X and a conditional distribution Q(x|x) from a space X toX the expression P × Q denotes the joint distribution P (x)Q(x|x) on X ×X . A.  ...

Pricing Network Resources: A New Perspective

Joy Kuri, Sharmili Roy
2007 2007 International Conference on Wireless Communications, Networking and Mobile Computing  
In our scheme, a SP needs to maintain just one single price for all the users.  ...  We show that under certain conditions, a very simple pricing scheme can ensure fair and efficient operation in the above sense.  ...  Clearly, there is an upper and a lower bound on these prices. We would like to compute these bounds.  ...

Data locality in MapReduce: A network perspective

Weina Wang, Lei Ying
2014 2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton)  
Thus the time of processing a remote task depends on the capacity of the communication network and the scheduling algorithm that allocates tasks.  ...  Inspired by this intuition, we study the data locality problem from a network perspective beyond just abstracting the effect of the communication network as a "longer processing time".  ...  As we argued, this may lead to underutilization on both the computing resources and the communication network capacity. Most related to our work is the prefetching idea [8, 17] .  ...

Suvadip Batabyal, Ozgur Ercetin
2022 arXiv   pre-print
For this, we first identify the frames containing a specific situation and assign them a high scale-of-importance (SI).  ...  The identification is made at the source using a tiny neural network (having a small number of hidden layers), which incurs a small computational resource, albeit at the cost of accuracy.  ...  We show that the proposed scheme is able to reduce the required power consumption by 2.21% and 38.5% for 720p and 2160p, respectively, while achieving a classification accuracy of 89% and 97.5%, for the  ...

Benefits of Semantics on Web Service Composition from a Complex Network Perspective [chapter]

Chantal Cherifi, Vincent Labatut, Jean-François Santucci
2010 Communications in Computer and Information Science  
In this work, we adopt a complex network perspective to perform a comparative analysis of the syntactic and semantic approaches used to describe WS.  ...  We show that WS interaction networks exhibit some of the typical characteristics observed in real-world networks, such as short average distance between nodes and community structure.  ...  A value of represents a random partition or the absence of community structure. Many real-world networks have a community structure [9] .  ...
