    • A method for anonymization of personal data is provided for protecting the privacy of a user while sharing user information with a third party. The method includes receiving from a user a domain name address associated with an intended website and an Internet Protocol (IP) address associated with the user and determining that the domain name address is an invalid domain name. The method may further include encrypting the IP address associated with the user by translating the IP address into a unique identifier, with the encryption being a one-way hashing process, and then sending the unique identifier and the invalid domain name address to the third party. The method may further include receiving, from the third party, the unique identifier and a third party content, with the third party content being based on the invalid domain name; decrypting the unique identifier by translating the unique identifier back into the IP address, associating the third party content with the IP address, and based on the IP address, providing the third party content to the user.

    • A system is disclosed for warping models made from geometric objects, such as electronic maps, to correct local distortions in the models without compromising model topology. A set of transformation functions are derived from relationships between points in a first model that match points in a second model. The transformation functions are then applied to the points in the first model to generate a new model with reduced distortion. In order to provide for reducing local distortions, warping is applied to selected corresponding regions of the first model and the second model by triangulating these regions and generating transformation functions for each corresponding pair of triangles. Topology preservation is achieved by identifying matching points in the first model and the second model that have a potential for causing topology deviations. Such matching points are then excluded from the process of developing transformation equations to be used in the warping process. Matching points with potential for causing topology deviations are identified by triangulating matching points in the selected regions of the first model and the second model and analyzing the resulting triangles.
    • 公开了一种用于对由几何对象(例如电子地图)制成的扭曲模型的系统,以校正模型中的局部失真,而不损害模型拓扑。 一组转换函数从与第二模型中的点匹配的第一模型中的点之间的关系导出。 然后将变换函数应用于第一模型中的点以生成具有减小的失真的新模型。 为了提供减少局部失真,通过对这些区域进行三角测量并为每个相应的三角形对生成变换函数,对第一模型和第二模型的选定对应区域进行翘曲。 通过识别具有引起拓扑偏差潜力的第一模型和第二模型中的匹配点来实现拓扑保存。 然后将这些匹配点从开发在翘曲过程中使用的变换方程的过程中排除。 通过对第一模型和第二模型的选定区域中的匹配点进行三角测量并分析所得到的三角形来标识具有引起拓扑偏差潜力的匹配点。

    • A presentation system accepts presentations or references to presentations from prospective presenters. Some or all of the presentations or references are stored in a database and referenced by keywords such that presentations to be presented in response to particular searches can be identified. A presentation manager handles accepting bids and settling terms between prospective presenters. The results of such processes might be stored in a presentation details database. A presentation server handles retrieving presentations from the presentation details database for presentation to users along with requests such as search results. Both the presentation manager and the presentation server can operate on a keywords-basis, wherein presentation terms specify keywords to be associated with particular presentations and the presentation server serves particular presentations based on keywords in a search query for which the presentations are to be returned. The association of keywords can be done using canonicalization so that, under certain conditions, different keywords are treated as the same keyword. Canonicalizations might include plural/singular forms, gender forms, stem word forms, suffix forms, prefix forms, typographical error forms, word order, pattern ignoring, acronyms, stop word elimination, etc. Conditions might include aspects of the search query state, such as the user's demographics, the page from which the search query was initiated, etc.
    • 演示系统接受来自潜在主持人的演示或参考。 一些或全部演示文稿或参考资料存储在数据库中,并由关键字引用,以便能够识别出响应特定搜索而呈现的演示文稿。 演示经理处理接受投标并在潜在主持人之间确定条款。 这些过程的结果可能存储在演示详细信息数据库中。 呈现服务器处理从呈现详细数据库检索演示文稿,以呈现给用户以及诸如搜索结果的请求。 呈现管理器和呈现服务器都可以基于关键字操作,其中呈现术语指定要与特定演示文稿相关联的关键字,并且呈现服务器基于要对其进行演示的搜索查询中的关键字进行特定演示。 可以使用规范化来完成关键字的关联,使得在某些条件下,不同的关键字被视为相同的关键字。 规范化可能包括复数/单数形式,性别形式,词干形式,后缀形式,前缀形式,排版错误形式,字序,模式忽略,首字母缩略词,停止词消除等。条件可能包括搜索查询状态的方面, 作为用户的人口统计,搜索查询的起始页面等。
