    • A process determines for a search string which, if any, of the strings in a text list have edit distance from the search string less than a threshold. The process uses dynamic programming on a grid with search string characters corresponding to rows and text characters corresponding to columns. For each text string, computation proceeds by columns. If successive text strings share a prefix, then the columns corresponding to the prefix are re-used. If the minimum value in a column is at least the threshold, then the prefix corresponding to that and previous columns causes edit distance to be at least the threshold. So the computation for the present text is abandoned, and computations for any other texts that share the prefix are avoided.
    • 过程确定搜索字符串,如果有的话,文本列表中的字符串中的任何字符串具有小于阈值的搜索字符串的编辑距离。 该过程在网格上使用动态规划,搜索字符串字符对应于与列对应的行和文本字符。 对于每个文本字符串,计算按列进行。 如果连续的文本字符串共享一个前缀,则重新使用与前缀相对应的列。 如果列中的最小值至少为阈值,则与该列和先前列相对应的前缀将使编辑距离至少为阈值。 因此,本文的计算被放弃,并且避免了共享前缀的任何其他文本的计算。

    • A process performs multiple evaluations of text simultaneously. There are multiple counters, each with pattern-amount pairs. The pattern-amount pairs are accumulated into a single finite-state machine, with each state having a list of (counter, value) pairs instead of a single value. While the finite-state machine is applied to text, a score for each counter is accumulated by summing values for the counter from value lists of visited states. With one state transition per character, evaluating text using one finite-state machine for multiple counters is more efficient than using separate finite-state machines for counters or patterns.
    • 进程同时执行文本的多个评估。 有多个计数器,每个都有模式量对。 模式量对被累积到单个有限状态机中,每个状态具有(计数器,值)对的列表而不是单个值。 当将有限状态机应用于文本时,每个计数器的得分通过对来自访问状态的值列表的计数器的值求和来累加。 每个字符有一个状态转换,使用多个计数器的一个有限状态机评估文本比使用单独的有限状态机来计数器或模式更有效。

    • The present invention provides techniques that may be used in connection with or as part of an online advertising auction-based exchange. Techniques are provided in which reserve prices, which may set minimum amounts for winning bids, are randomized. For a set of one or more auctions during a time period to which a single reserve price would otherwise apply, one or more randomized reserve prices may instead be applied. Use of randomized reserve prices can smooth otherwise abrupt responses resulting from advertiser bid modifications, and lead to desirable marketplace characteristics or marketplace optimization.
    • 本发明提供了可以与基于在线广告拍卖的在线交流相结合或作为其一部分使用的技术。 提供了一些技术,其中可以设定中标的最低金额的储备价格是随机的。 对于一个或多个拍卖在一个单独的预留价格将适用的时间段内,可以替代地应用一个或多个随机的储备价格。 使用随机储备价格可以平滑,否则由于广告客户出价修改而产生的突然反应,并导致理想的市场特征或市场优化。
