    • Reputation systems have been used to promote trust between participants in activities including online activities such as online market places. Existing online market places provide a reputation system which is a simple cumulative registry of user ratings on a given market place member. However, this simple system is open to abuse in situations where, for example, many positive ratings are given in a fraudulent manner. By modeling both reputation of participants and required reputation of participants an improved reputation system is provided. The required reputation may be thought of as a threshold, referred to herein as a required threshold, which may be used in determining how to update an indication of the reputation of a participant in the activity. The reputation system is able to learn information about required reputation and reputation of participants using an update process which is robust to participants who consistently give feedback of a particular type.
    • 信誉系统已被用于促进参与者之间的信任,包括在线活动,如在线市场。 现有的在线市场地点提供了一个声誉系统,这是一个简单的累积登记的用户评级在给定的市场成员。 然而,这种简单的系统在例如以欺诈方式给出许多正面评级的情况下是可以滥用的。 通过对参与者的声誉和参与者的声誉进行建模,提供了改进的声誉系统。 所需的信誉可以被认为是阈值,这里称为所需阈值,其可用于确定如何更新活动中参与者的信誉的指示。 信誉系统能够使用对持续给出特定类型的反馈的参与者是稳健的更新过程来学习关于参与者的所需信誉和声誉的信息。

    • In particular, systems and methods are provided for delivering a discount using a virtual currency. Inventive systems and methods offer a high perceived savings value to an end-user while maintaining the perception of product value. Further, systems and methods for providing a discount are described which impose little or no cost on the service or product provider. An embodiment of an inventive method includes presenting a display of a price paid by a consumer without access to the virtual currency along with a display of an amount payable by the end-user in actual currency in combination with an amount payable in virtual currency by an end-user of an inventive system. The end-user perceives a benefit to using the virtual currency since the price paid in actual currency is less than the displayed price to be paid by a consumer without access to the virtual currency.

    • A replication process to provide fault tolerance for a streaming signal in a computer network. In one embodiment, the original or source signal is sent to several splitters which, in turn, each make copies of the signal and send the copies into a second layer of devices, which are referred to as “concentrators.” A given concentrator receives as input one or more copies of the source signal. In a preferred embodiment, a given concentrator receives two copies of the source signal from at least two different splitters. The concentrators process the incoming streaming signal copies, for example, by merging them into a single or composite copy of the original source signal according to a given processing algorithm. The output of a given concentrator may then be fed into a splitter, with the process then being repeated if desired to make an arbitrary large number of copies of the signal. At the end of the replication process, the output of a splitter or a concentrator is fed directly or indirectly to an end user. The replication process is fault-tolerant, and thus the end user's signal is not interrupted regardless of signal or equipment problems within the distribution mechanism.
    • 为计算机网络中的流信号提供容错的复制过程。 在一个实施例中,原始或源信号被发送到多个分离器,这些分离器又分别进行信号的副本并将副本发送到被称为“集中器”的第二层设备。 给定的集中器作为输入接收源信号的一个或多个副本。 在优选实施例中,给定的集中器从至少两个不同的分配器接收源信号的两个拷贝。 集中器例如通过根据给定的处理算法将它们合并成原始信号源的单个或复合副本来处理输入的流传输信号副本。 然后可以将给定的聚光器的输出馈送到分离器中,如果需要,则重复该过程以产生任意大量的信号。 在复制过程结束时,分离器或集中器的输出被直接或间接地馈送给终端用户。 复制过程是容错的,因此无论分发机制中的信号或设备问题如何,最终用户的信号都不会中断。
