The only previously known solution method for proxy bidding in combinatorial auctions requires the auctioneer to run the auction with myopic bidders to determine the outcome. In this paper we present a radically different approach that computes the bidders' allocation of their attention across the bundles only at the points at which they change their bidding patterns. This algorithm has several advantages over alternatives, including that it computes exact solutions and is invariant to the magnitude of the bids. We present a general framework and apply it to Ausubel and Milgrom's APA mechanism and our own simple combinatorial proxy auction. We present an example in which the approach is applied to a multistage proxy auction, and report on some preliminary computational results.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116091657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This algorithm takes two schemata of EDI messages as the input, computes the basic similarity between each pair of elements by comparing their textual description and data type. Then, it computes the structural similarity value basing on the structural neighbors of each element (ancestor, sibling, immediate children and leaf elements) with an aggregation function. The basic similarity and structural similarity values are used in the pair wise element similarity computing which is the final similarity value between two elements.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134431490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the availability of cheap pseudonyms, incentive schemes that are based on reward and punishment are vulnerable to the whitewashing attack, where users continuously discard their old identity and acquire a new one to escape the consequences of their bad behavior. In this paper, we study the implications of the whitewashing attack from an evolutionary perspective. Not surprisingly, the whitewashing attack degrades the evolutionary stability of strategies that are otherwise stable. In particular, the tit-for-tat strategy and its variant, probabilistic TFT, are not stable against white-washers, unless identity costs are sufficiently large. In addition, we extend the indirect reciprocity model and find that discriminators can defeat whitewashers only if the probability to cooperate with strangers is small enough, which in turn degrades social welfare.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115897312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EMMIL structures bring together three entity types - seller, buyer and third party logistics service provider - within the same transaction thus enabling combined total cost optimisation for purchase and delivery. We give an overview of the general principles of EMMIL then present the case of buyer oriented marketplaces in more detail. A composite procurement auction is introduced in which bids from sellers of goods and from logistics providers are combined. After formulating the optimisation problem, we investigate possible solution methods for different scenarios.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125160589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novel feature of this work is that the system learns and uses models of both user preferences and the user's intentional context. Both learning types are based on the same user input, but elicit different aspects of the user model. User preference is learned via support vector machine (SVM) with user ratings on the products, whereas the user's intentional context is inferred using a hidden Markov model (HMM) from given product access sequences. We propose a product recommendation scheme based on an analysis on both the preference and intentional context model. An empirical analysis shows that the hybrid approach is able to support users with different preference structures and intentional contexts.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127246238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper contributes to the development of an optimization model that aims to determine the optimal amount to be invested in technical security mechanisms and insurance policies.
