    • A method of forming a mask. The method includes providing design information of a design layer. The design layer includes M original design features and N original dummy features. The method further includes (i) creating a cluster of P representative dummy features, P being a positive integer less than N, (ii) performing OPC for the cluster of the P representative dummy features but not for the N original dummy features, resulting in P OPC-applied representative dummy features, and (iii) forming the mask including N mask dummy features. The N mask dummy features are identical. Each mask dummy feature of the N mask dummy features of the mask has an area which is a function of at least an area of an OPC-applied representative dummy feature of the P OPC-applied representative dummy features. The N mask dummy features have the same relative positions as the N original dummy features.
    • 一种形成掩模的方法。 该方法包括提供设计层的设计信息。 设计层包括M原始设计特征和N个原始虚拟特征。 该方法还包括(i)创建P代表虚拟特征的聚类,P是小于N的正整数,(ii)对P代表虚拟特征的簇进行OPC,而不对N个原始伪特征执行OPC,导致 P OPC应用的代表虚拟特征,以及(iii)形成包括N个掩模虚拟特征的掩模。 N个掩码虚拟特征是相同的。 掩模的N个掩模虚拟特征的每个掩码虚拟特征具有至少是应用于P OPC应用的代表虚拟特征的OPC应用的代表性虚拟特征的区域的函数的区域。 N个掩模虚拟特征具有与N个原始虚拟特征相同的相对位置。

    • A technique is provided for providing an aggregate tag view of a website that comprises a plurality of webpages that each has a corresponding URL. A tag is a set of one or more words that have been associated with a URL and is typically created by a user to describe content of the webpage corresponding to the URL. Initially, a request is received to display information pertaining to a website. In response to the request, a plurality of tags associated with the website is displayed. A first subset of the plurality of tags is associated with a particular URL. A second subset of the plurality of tags is associated with one or more URLs that are not the particular URL. Alternatively, or in addition to an aggregate tag view tag-related information for each URL of the website is provided, in response to the initial request.
    • 提供了一种用于提供包括多个网页的网站的聚合标签视图的技术,每个网页各自具有对应的URL。 标签是与URL相关联的一个或多个单词的集合,并且通常由用户创建以描述对应于URL的网页的内容。 最初,接收到显示有关网站的信息的请求。 响应于该请求,显示与网站相关联的多个标签。 多个标签的第一子集与特定URL相关联。 多个标签的第二子集与一个或多个不是特定URL的URL相关联。 或者,或除了聚合标签之外,还提供了响应于初始请求的网站的每个URL的标签相关信息。

    • Novel, computationally efficient schemes for deterministic wavelet thresholding with the objective of optimizing maximum-error metrics are provided. An optimal low polynomial-time algorithm for one-dimensional wavelet thresholding based on a new dynamic-programming (DP) formulation is provided that can be employed to minimize the maximum relative or absolute error in the data reconstruction. Directly extending a one-dimensional DP algorithm to multi-dimensional wavelets results in a super-exponential increase in time complexity with the data dimensionality. Thus, novel, polynomial-time approximation schemes (with tunable approximation guarantees for the target maximum-error metric) for deterministic wavelet thresholding in multiple dimensions are also provided.
    • 提供了用于确定性小波阈值的计算有效方案,其目的是优化最大误差度量。 提供了一种基于新动态规划(DP)公式的一维小波阈值优化的最优低次多项式时间算法,可用于最小化数据重构中的最大相对误差或绝对误差。 将一维DP算法直接扩展为多维小波导致数据维度在时间复杂度方面的超指数增长。 因此,还提供了用于确定性小波阈值在多个维度中的新颖多项式时间近似方案(对于目标最大误差度量具有可调近似保证)。

    • A method and apparatus for client-side federated search is provided. The user subscribes to a number of information providers, wherein a list of the information providers for the user is stored at a search engine. When the user at a client device submits a search query to the search engine, the search engine responds by sending general search results to the client device, along with search instructions that instruct the client device how to automatically initiate a search at information providers in which the user is interested. Without any further input from the user, the client device uses the search instructions to initiate searches at information providers in which the user is interested. When the client receives search results from the information providers, the client device displays the general search results concurrently with the information provider search results.
    • 提供了一种用于客户端联合搜索的方法和装置。 用户订阅多个信息提供者,其中用户的信息提供者列表存储在搜索引擎中。 当客户端设备上的用户向搜索引擎提交搜索查询时,搜索引擎通过向客户端设备发送一般搜索结果以及指示客户端设备如何在信息提供者中自动发起搜索的搜索指令来进行响应, 用户感兴趣 客户端设备没有来自用户的任何进一步的输入,使用搜索指令来发起用户感兴趣的信息提供者的搜索。 当客户端从信息提供者接收到搜索结果时,客户端设备与信息提供商搜索结果同时显示一般搜索结果。
