A model of targeted advertising with customer recognition

A two-period duopoly model is developed to examine the competitive effects of targeted advertising with customer recognition （TACR）. In the model, two competing firms sell goods to end consumers in the first period, during which customer recognition is obtained. In the second period, advertising can be targeted toward different consumer types. Advertising is assumed to be persuasive in the way that consumer valuation is increased. Equilibrium decisions and profits in each period are derived, showing that the firm who loses the current competition will win in the future. As a result, forward-looking firms price less aggressively so that their long-term profits can be enhanced with the help of TACR. Particularly, TACR improves profits through three important effects： valuation increasing, customer poaching, and anti-competition. Finally, this paper investigates the welfare issues, showing that firms enhance profits at the expense of consumer surplus. It is, therefore, suggested that public sectors take a step to protect consumers with the rapid development of targeting technology.

Optimal targeted advertising strategies based on consumers' value attributes

To evaluate the effects of consumers＇ value attributes on a firm＇s marketing strategies with targeted advertising, each consumer＇s value is measured according to the consumer＇s consuming behavior and consumption features. The baseline model in which a firm sends targeted advertising to myopic consumers with constant valuations is established. The results showthat, when a firm sells products to consumers with distinct values using the strategies of targeted advertising and discriminative price, the firm＇s equilibrium profit with targeted advertising may not always be higher than that using mass advertising, which depends on the ratio of high-value and low-value consumers. Then, three extension models are constructed.First, the firm sends targeted advertising to consumers with different targeting precisions. Secondly, the firm invests in the targeting precision of targeted advertising. Finally, the deliberation cost of rational consumers accepting the discriminative price and targeted advertising is considered. The results indicate that it is profitable for a firm to send targeted advertising to consumers with different value attributes.

Imperfect targeted advertising with two-period competition

A two-period model is developed to investigate the competitive effects of targeted advertising with imperfect targeting in a duopolistic market. In the first period, two firms compete in price in order to recognize customers. In the second period, targeted advertising plays an informative role and acts as a price discrimination device. The firms＇ optimal advertising and pricing strategies under imperfect targeting are compared with those under perfect targeting. Equilibrium decisions show that, under imperfect targeting, when the advertising cost is low enough, both firms will choose to target ads at the rivals＇ old segments. This equilibrium, which could not exist under perfect targeting, results in two opposite results. When cost is high, the effect of mis-targeting will soften price competition and increase profits; on the contrary, when cost is low enough, it will lead to aggressive price competition and profit loss with the increase of imperfect targeting, so firms may have incentives to reduce the mis- targeting degree.

Understanding advertisements from the perspective of relevance theory

This paper approaches advertisements on the basis of relevant theory. It elaborates how the advertiser as addresser in communication succeed in conveying his intention for publicity and how the recipient as addressee takes advantage of different types of relevant devices in reasoning out the communicative purposes from four different angles, namely, non-stereotypical interpretation of advertisements, psychological requirements of the recipient as addressee in advertisements, advertisements as explicit information and the situational approach to implicit meanings of advertisements. It aims at providing guidance for advertisement planning and translation by means of the exposure of rules underlying advertisements.

The advertisement call of the giant spiny frog Paa spinosa

We analyzed the advertisement call of Paa spinosa at Yuliang Mountain,Lanxi,Zhejiang Province,in eastern China.Temporal and spectral call parameters were analyzed,along with call intensity.Calls comprised of three to seven notes,the last of which had the longest duration.Three formants(harmonics)were clearly distinguishable from the audio spectrogram.The dominant frequency ranged from 411-1534 Hz,and was either the first or the second formant.The number of notes within a call was positively correlated to air temperature,so that calls contained more notes during the day.Also,the dominant frequency appeared to be lower at the highest temperature.

Contextual advertising is a major revenue source for today＇s companies. Keyword extraction is a key step in this kind of advertising, through which appropriate advertising keywords are extracted from Web pages so that corresponding ads can be triggered. This paper describes a system that learns how to extract keywords from web pages for advertisement targeting. Firstly a text network for a single webpage is build, then PageRank is applied in the network to decide on the importance of a word, finally top-ranked words are selected as keywords of the webpage. The algorithm is tested on the corpus ofblog pages, and the experimental results prove practical and effective.

TCP-Rab： a receiver advertisement based TCP protocol

With the evolution of network technologies, the deficiencies of TCP protocol are becoming more and more distinct. The new TCP implementation, called Receiver Advertisement Based TCP (TCP-Rab) proposed here to eliminate these deficiencies, adopts two basic mechanisms: (1) Bandwidth Estimation and (2) Immediate Recovery. Bandwidth estimation is carried out at the receiver, and the result is sent back to the sender via the acknowledgments. Immediate Recovery guarantees high performance even in lossy link. Rab can distinguish the reason for packet loss, and thus adopt appropriate recovery strategy. For loss by network congestion, it will back off its congestion window, and for loss by link errors, it will recover the congestion window immediately. Simulations indicated that Rab has superiority over other TCP implementations.

The Effect of Verbal Anchoring on the Processing of Advertising Pictorial Metaphors

Although investigating metaphors in advertising is gaining in popularity, there are still certain unresolved arguments, such as the interaction between elements of different modalities. This study,composed of three behavioral experiments, aims to identify how verbal anchoring(literal anchoring, metaphor anchoring and unrelated anchoring) influences the processing of pictorial metaphors in advertising, by observing the cognitive and affective indicators, advertising comprehension and advertising likeability. The results showed 1) that metaphors in pictorial modality were recognized more quickly than those in verbal modality, 2) that verbal anchoring facilitated participants ’ comprehending and appreciating of pictorial metaphors and 3) that literally-anchored metaphors with a moderate level of novelty yielded the most favorable cognitive responses. The study not only enriches the existing theoretical framework of multimodal metaphors in advertising, but also proposes an optimal match between pictorial metaphors and verbal elements, for advertisers and manufacturers to design effective multimodal advertisements.

Impact of thumb up sharing advertising in social media

“Thumb up advertising”is a new and effective way to spread shared advertising in social media.How the retailer adapts“thumb up advertising”in marketing with a game theory model is analyzed.The results show that when the retailer chooses to thumb up the advertising in Moments,a higher reward will increase the equilibrium price but hurt the retailer s expected profit;if the consumers can more easily reach the thumb up amount,the retailer will charge a higher price,and possibly gain more profit.When the retailer chooses thumb up at the end of the advertising context,a higher reward will increase the equilibrium price and the retailers expected profit will increase/decrease.If the consumers are easier to reach the thumb up amount,the retailer will charge a higher price,and may get more profit.If a consumer s click cost of clicking the sharing advertising is higher,the retailer charges a lower price;and if the consumer s additional perceived value from the advertising is higher,the retailer charges a higher price and reaps more profit.

Intelligent outdoor video advertisement recommendation system based on analysis of audiences' characteristics

An integrated implementation framework of an intelligent recommendation system for outdoor video advertising is proposed, which is based on the analysis of audiences＇ characteristics. Firstly, the images of the scene and the people who view the video advertisements are captured by the net- work camera deployed on the video advertising terminal side. Then audiences＇ characteristics can be obtained by applying computer vision technologies ： face detection, face tracking, gender recogni- tion and age estimation. Finally, an intelligent recommendation algorithm is designed to decide the most fitting video ads for each terminal according to multi-dimensional statistical information of its reover, a novel face detection method and a new face tracking method have been proposed to meet the practical requirements of the system, of which the average Fl-score is O. 988 and 0. 951 respec- tively.
