Multi-Touch Attribution Based Budget Allocation in Online Advertising
Budget allocation in online advertising deals with distributing the campaign
(insertion order) level budgets to different sub-campaigns which employ
different targeting criteria and may perform differently in terms of
return-on-investment (ROI). In this paper, we present the efforts at Turn on
how to best allocate campaign budget so that the advertiser or campaign-level
ROI is maximized. To do this, it is crucial to be able to correctly determine
the performance of sub-campaigns. This determination is highly related to the
action-attribution problem, i.e. to be able to find out the set of ads, and
hence the sub-campaigns that provided them to a user, that an action should be
attributed to. For this purpose, we employ both last-touch (last ad gets all
credit) and multi-touch (many ads share the credit) attribution methodologies.
We present the algorithms deployed at Turn for the attribution problem, as well
as their parallel implementation on the large advertiser performance datasets.
We conclude the paper with our empirical comparison of last-touch and
multi-touch attribution-based budget allocation in a real online advertising
setting.Comment: This paper has been published in ADKDD 2014, August 24, New York

Privacy-preserving targeted advertising scheme for IPTV using the cloud
In this paper, we present a privacy-preserving scheme for targeted advertising via the Internet Protocol TV (IPTV). The scheme uses a communication model involving a collection of viewers/subscribers, a content provider (IPTV), an advertiser, and a cloud server. To provide high quality directed advertising service, the advertiser can utilize not only demographic information of subscribers, but also their watching habits. The latter includes watching history, preferences for IPTV content and watching rate, which are published on the cloud server periodically (e.g. weekly) along with anonymized demographics. Since the published data may leak sensitive information about subscribers, it is safeguarded using cryptographic techniques in addition to the anonymization of demographics. The techniques used by the advertiser, which can be manifested in its queries to the cloud, are considered (trade) secrets and therefore are protected as well. The cloud is oblivious to the published data, the queries of the advertiser as well as its own responses to these queries. Only a legitimate advertiser, endorsed with a so-called {\em trapdoor} by the IPTV, can query the cloud and utilize the query results. The performance of the proposed scheme is evaluated with experiments, which show that the scheme is suitable for practical usage

Monitoring food marketing to children: A joint Nordic monitoring protocol for marketing of foods and beverages high in fat, salt and sugar (HFSS) towards children and young people
The protocol describes methods for how to monitor marketing of foods and beverages high in fat, salt and sugar towards children and young people at a given time as cross-sectional studies, as well as allowing for monitoring of trends. The data provided could also be used for evaluation purposes, for instance providing relevant data for evaluating regulation practices and schemes in the respective countries; to study advertising and marketing practices, contents and forms over time. In addition to being a tool for monitoring purposes within each country, the protocol will also enable comparisons between the Nordic countries by establishing a joint understanding on how each marketing channel should be monitored. The protocol has been developed as a Nordic project between representatives and experts from Iceland, Finland, Sweden, Denmark and Norway together with international experts

Evaluating implementation of the WHO set of recommendations on the marketing of foods and non-alcoholic beverages to children: Progress, challenges and guidance for next steps in the WHO European Region
This paper describes the status of the implementation of the WHO Set of Recommendations on the Marketing of Foods and Non-alcoholic Beverages to Children (2010). The Set of Recommendations, adopted by the World Health Assembly, urges Member States to reduce the impact on children of the marketing of energy-dense, highly processed foods and beverages that are high in saturated fats, trans fats, free sugars and/or salt (HFSS). A growing body of independent monitoring and research indicates that existing policies and regulations are markedly insufficient to address the continuing challenges in this field. This report identifies loopholes, ongoing challenges, and factors that Member States need to consider to effectively limit the harmful impact that HFSS food marketing has on children, their health and their rights.
Policies and regulations tend to use narrow definitions and criteria (they frequently apply to pre-digital media only, to younger children and not to adolescents, and to “child-directed” media, rather than those with the greatest child audiences), and they almost never address the complex challenges of crossborder marketing. This situation can be explained, in part, by the strong scrutiny and opposition that countries have faced from parts of the private sector, and by weak self-regulatory schemes. As a result, and in order to ensure that States uphold their legal obligations to protect the child’s right to health and related rights, the World Health Assembly requested that WHO provides additional technical support to Member States in implementing the Set of Recommendations. This report identifies challenges States need to address

Understanding the Detection of View Fraud in Video Content Portals
While substantial effort has been devoted to understand fraudulent activity
in traditional online advertising (search and banner), more recent forms such
as video ads have received little attention. The understanding and
identification of fraudulent activity (i.e., fake views) in video ads for
advertisers, is complicated as they rely exclusively on the detection
mechanisms deployed by video hosting portals. In this context, the development
of independent tools able to monitor and audit the fidelity of these systems
are missing today and needed by both industry and regulators.
In this paper we present a first set of tools to serve this purpose. Using
our tools, we evaluate the performance of the audit systems of five major
online video portals. Our results reveal that YouTube's detection system
significantly outperforms all the others. Despite this, a systematic evaluation
indicates that it may still be susceptible to simple attacks. Furthermore, we
find that YouTube penalizes its videos' public and monetized view counters
differently, the former being more aggressive. This means that views identified
as fake and discounted from the public view counter are still monetized. We
speculate that even though YouTube's policy puts in lots of effort to
compensate users after an attack is discovered, this practice places the burden
of the risk on the advertisers, who pay to get their ads displayed.Comment: To appear in WWW 2016, Montr\'eal, Qu\'ebec, Canada. Please cite the
