Efficient Sampling for Better OSN Data Provisioning
[article]
2016
arXiv
pre-print
Preserved Fulltext
In this paper, we propose a method for OSNs to provide samples of the user graph of tunable size, in non-intersecting increments, with sample selection that can be weighted to enhance accuracy when estimating ...
APIs let OSN providers monetize the release of data while helping control measurement load, e.g. by providing samples with different cost-granularity tradeoffs. ...
Much research activity (see Section II) has focused both on developing strategies for efficiently using these resources and estimating OSN properties from the subsets of data so obtained. ...

There are several challenges for performing dynamic analysis. One is fast data collection and timely processing, where an unbiased and efficient graph sampling algorithm can play an important role. ...
Also, collecting dynamic data raises challenges for information storage; therefore, the temporal and spatial dependence between different data items can be utilized for better compression. ...

The SDP can construct a verification object for the data consumer based on these information. Extensive experiments ran on a real Twitter dataset confirm that our schemes are effective and efficient. ...
Data consumers in the basic scheme utilize the public APIs to collect the sampled social data and compare them with their received social data. ...
OVERVIEW OF BASIC SCHEME Recall that the OSN operator also provides the public APIs for data consumers to obtain sampled social contents. ...

Recent work has proposed decentralized OSNs as more privacy-preserving alternatives to the prevailing OSN model. We present three schemes for decentralized OSNs. ...
However, two aspects of many current OSNs have important implications with regards to privacy: their centralized nature and their acquisition of rights to users' data. ...
For each of these sample operations, we created a Meta Group consisting of all available VISs. ...

The effectiveness and scalability of UnifyDR are showcased by experiments performed on data generated using the TPC-DS benchmark and a trace of the Gowalla OSN for the OLAP queries and OSN service use-case ...
The key objective of data placement is to obtain a partitioning (possibly allowing for replicas) of a set of data-items into distributed nodes that minimizes the overall network communication cost. ...
To better motivate the need for scalable solutions to the data placement problem, we consider two popular application domains-(1) Online analytical processing (OLAP), and (2) Online social networks (OSNs ...

One important proposal under discussion is whether to privatize water provision. ...
Using the variation in ownership of water provision across time and space generated by the privatization process, we find that child mortality fell 8 percent in the areas that privatized their water services ...
Privatization increased efficiency and profitability. Before privatization, OSN was overstaffed and absenteeism was high. ...
