In this paper, we introduce a formal bidding strategy model for specification of flexible and complex bidding strategies. The formal model is defined as a layered bidding strategy model (LBSM), which can be represented using notations borrowed from UML activity diagrams. To support real-time and efficient reasoning, the formal model is converted into a rule-based bidding strategy model (RBSM) specified in bidding strategy language (BSL) that can be directly executed by a reasoning module of a bidding agent. We present an algorithm for converting an LBSM to an RBSM, and an algorithm to drive the reasoning engine. Finally, we develop a prototype agent-based online auction system using JADE, and illustrate how flexible and complex bidding strategies can be precisely specified and efficiently executed.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115649402","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 system allows users to use any public information available on the Internet for defining notification criteria. This opens up a huge repository of dynamic information related to stock investments such as current stock prices, daily trading volumes, current offer prices and volumes, current bid prices and volumes, n-day trading averages, interest rates, currency exchange rates, etc. All this public information can be used to define the stocks monitoring criteria based on the specific investor requirements. Based on the defined criteria, notification messages are generated and sent to the investor notifying him/her whenever the criteria are met. A number of applications related to stocks investment can benefit from this system.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123045558","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}

Embedding a monitoring mechanism, such as our Continuous Compliance Assurance (CCA) module, into a technology solution for inter-organizational information sharing, if not too costly in processing, would ensure appropriately timed compliance enforcement. A test-bed, which incorporated our CCA module, was built to capture realistic processing statistics. Through this test-bed, we have observed a limiting factor imposed by XML based processing. The feasibility of CCA rests on the reduction of these limiting factors. Accordingly we present two approaches to mitigate these issues.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117227088","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 analysis results show that our approach can detect shills and that using Dempster-Shafer theory to combine multiple sources of evidence of shilling behavior can reduce the number of false positive results that would be generated from a single source of evidence.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127360952","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}

It is an enabler for sharing information and services among organizations while respecting the authorization decisions of each organization. Federation can be realized in two ways: 1) Conventional federation that is based on a multilateral agreement among participants and 2) Peer-to-peer (P2P) federation that is based on bilateral agreements. In this paper, we introduce a P2P federated authentication system based on the OASIS security assertion markup language (SAML) version 2.0 standard. The P2P federation model is simpler and more flexible than the conventional federation model even though managing peer relationships becomes a burden if the number of peers gets unmanageably large. The conventional federation model and P2P federation model are not mutually exclusive. The two models can co-exist and interoperate.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125929317","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}

We also propose a technique to shorten the path an operand takes by exploiting the copies of the operand distributed over the architecture.

This is compounded by online auction sources being non-cooperative in providing auction data, usually citing \"security and privacy'' as reasons for not wanting to help.  This paper presents a software tool that can extract data from various online auction sources.  The system is able to collect all the data for a given search criteria on auctions that have completed, and also returns later to collect the data from ongoing auctions once they have completed (without user intervention).  We share our experiences from the development process and describe the challenges that must be overcome to successfully set up such a system. The data collected is used to analyse the behaviour and bidding patterns of sellers and buyers that are engaged in online auctions.  The work presented in this paper represents the first serious attempt at creating an openly available software tool and establishing a repository of online auction data that will be free for use by other researchers.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126772013","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 interface is divided into two sections with right half supporting the ability to draw profile curve both symmetric and asymmetric. This query can be further refined using the left half which provides contextual based information. Using a curve-matching algorithm the software then searches the database and returns a series of potential matches sorted by the percentage of similarity between the curves.
