Uncovering Download Fraud Activities in Mobile App Markets [PDF]
International Conference on Advances in Social Networks Analysis and Mining, 2019 Download fraud is a prevalent threat in mobile App markets, where fraudsters manipulate the number of downloads of Apps via various cheating approaches. Purchased fake downloads can mislead recommendation and search algorithms and further lead to bad user experience in App markets. In this paper, we investigate download fraud problem based on a company'

Optimal Download Cost of Private Information Retrieval for Arbitrary Message Length [PDF]
arXiv, 2016 A private information retrieval scheme is a mechanism that allows a user to retrieve any one out of $K$ messages from $N$ non-communicating replicated databases, each of which stores all $K$ messages, without revealing anything about the identity of the desired message index to any individual database.

On full text download and citation distributions in scientific-scholarly journals [PDF]
arXiv, 2015 A statistical analysis of full text downloads of articles in Elseviers ScienceDirect covering all disciplines reveals large differences in download frequencies, their skewness, and their correlation with Scopus-based citation counts, between disciplines, journals, and document types.

Scale-free download network for publications [PDF]
Chin.Phys.Lett. 21 (2004) 1855-1857, 2004 The scale-free power-law behavior of the statistics of the download frequency of publications has been, for the first time, reported. The data of the download frequency of publications are taken from a well-constructed web page in the field of economic physics (http://www.unifr.ch/econophysics/).

PIR schemes with small download complexity and low storage requirements [PDF]
arXiv, 2016 In the classical model for (information theoretically secure) Private Information Retrieval (PIR), a user wishes to retrieve one bit of a database that is stored on a set of $n$ servers, in such a way that no individual server gains information about which bit the user is interested in.

Coding for Fast Content Download [PDF]
arXiv, 2012 We study the fundamental trade-off between storage and content download time. We show that the download time can be significantly reduced by dividing the content into chunks, encoding it to add redundancy and then distributing it across multiple disks. We determine the download time for two content access models - the fountain and fork-join models that

On the Delay-Storage Trade-off in Content Download from Coded Distributed Storage Systems [PDF]
arXiv, 2013 In this paper we study how coding in distributed storage reduces expected download time, in addition to providing reliability against disk failures. The expected download time is reduced because when a content file is encoded to add redundancy and distributed across multiple disks, reading only a subset of the disks is sufficient to reconstruct the ...

An Index for SSRN Downloads [PDF]
Journal of Informetrics 10(1) (2016) 9-28, 2015 We propose a new index to quantify SSRN downloads. Unlike the SSRN downloads rank, which is based on the total number of an author's SSRN downloads, our index also reflects the author's productivity by taking into account the download numbers for the papers.

Is your EPL attractive? Classification of publications through download statistics [PDF]
Europhys. Lett. 108 (2014) 50011, 2014 Here we consider the download statistics of EPL publications. We find that papers in the journal are characterised by fast accumulations of downloads during the first couple of months after publication, followed by slower rates thereafter, behaviour which can be represented by a model with predictive power.
