Efficient Sampling for Better OSN Data Provisioning [article]

Nick Duffield, Balachander Krishnamurthy
2016 arXiv   pre-print
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.  ...

Understanding user behavior in online social networks: a survey

Long Jin, Yang Chen, Tianyi Wang, Pan Hui, Athanasios V. Vasilakos
2013 IEEE Communications Magazine  
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.  ...

Verifiable Keyword-Based Semantic Similarity Search on Social Data Outsourcing

Yizhu Zou, Xin Yao, Zhigang Chen, Ming Zhao
2019 IEEE Access  
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.  ...

Network level footprints of facebook applications

Atif Nazir, Saqib Raza, Dhruv Gupta, Chen-Nee Chuah, Balachander Krishnamurthy
2009 Proceedings of the 9th ACM SIGCOMM conference on Internet measurement conference - IMC '09  
These insights help provide guidelines for OSNs and application developers. We have also made the data studied here publicly available to the research community.  ...  Little information is available on the network impact of OSNs, although there is every expectation that the volume and diversity of traffic due to OSNs is set to explode.  ...  Lacking knowledge of the internal Facebook provisioning and architecture, we surmise this difference is due to a more efficient storage/update mechanism for Facebook users' statuses. (5) Data caching has  ...

Privacy, cost, and availability tradeoffs in decentralized OSNs

Amre Shakimov, Alexander Varshavsky, Landon P. Cox, Ramón Cáceres
2009 Proceedings of the 2nd ACM workshop on Online social networks - WOSN '09  
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.  ...

UnifyDR: A Generic Framework for Unifying Data and Replica Placement

Ankita Atrey, Gregory Van Seghbroeck, Higinio Mora, Bruno Volckaert, Filip De Turck
2020 IEEE Access  
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  ...

Newton Masinde, Kalman Graffi
2020 arXiv   pre-print
While users aim for privacy and data sovereignty, often the providers aim to monetize the data they store.  ...  Secondly, it elaborates on the building blocks for P2P frameworks that allow the creation of such sophisticated and demanding applications, such as user/identity management, reliable data storage, secure  ...  Hence, as noted in [155] , the use of replication is preferred for OSNs as the data is frequently updated, while the use of erasure codes is a better choice in systems handling large static data for archival  ...

Water for Life: The Impact of the Privatization of Water Services on Child Mortality

Sebastian Galiani, Paul Gertler, Ernesto Schargrodsky
2005 Journal of Political Economy  
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.  ...
