    • A crowdsourcing data structuring system and method for capturing unstructured data from the Web and adding structure by placing the data in a document that is accessible by others in a cloud computing environment. Using crowdsourcing, the unstructured data is annotated, amended, and verified to add structure to the unstructured data. An anchor and update module convert the data to a pointer that links the document to the data at an information source and stores the pointer in the document rather than the data itself. The data displayed in the document is updated whenever the information source is updated. A contribution module allows users to add data to the document, a validation module allows users to determine the validity of the data linked to in the document, and an expert ranking module allows users to rank the expert or contributor of the data in the document.
    • 用于从Web获取非结构化数据并通过将数据放置在可由其他人在云计算环境中访问的文档中来添加结构的众包数据结构化系统和方法。 使用众包,非结构化数据进行注释,修改和验证,以向非结构化数据添加结构。 锚和更新模块将数据转换为将文档链接到信息源上的数据的指针,并将指针存储在文档中而不是数据本身。 每当更新信息源时,文档中显示的数据都会更新。 贡献模块允许用户向文档添加数据,验证模块允许用户确定文档中链接的数据的有效性,专家排名模块允许用户对文档中的数据的专家或贡献者进行排名。

    • A method and computer product for rendering real-time three-dimensional images on a display based on view manipulation of prestored depth images in a global coordinate space. First, a layered depth image is generated from multiple depth images based on a predetermined display viewpoint. If the determined viewpoint is within a predetermined threshold of the layered depth image, the generated layered depth image is warped based on the determined display viewpoint, pixels from the layered depth image are splatted onto the warped image, and an output image is generated and displayed based on the splat pixels. If the determined viewpoint is outside the predetermined threshold of the previously generated layered depth image, a next closest layered depth image is generated. If the next closest layered depth image is not fully generated, the previously generated layered depth image is used to generate an output image. If the next closest layered depth image is fully generated, the process is repeated for the generated next closest layered depth image.
    • 一种用于基于在全局坐标空间中预先存储的深度图像的视图操纵在显示器上呈现实时三维图像的方法和计算机产品。 首先,基于预定的显示视点从多个深度图像生成分层深度图像。 如果所确定的视点在分层深度图像的预定阈值内,则基于所确定的显示视点来扭曲所生成的分层深度图像,并将来自分层深度图像的像素分解成弯曲图像,并且生成并显示输出图像 基于splat像素。 如果确定的视点在先前生成的分层深度图像的预定阈值之外,则生成下一个最接近的分层深度图像。 如果未完全生成下一个最接近的分层深度图像,则使用先前生成的分层深度图像来生成输出图像。 如果完全生成下一个最接近的分层深度图像,则对于生成的下一个最近的分层深度图像重复该过程。

    • A searchable web site discovery and recommendation system and method for discovering and recommending searchable web sites to a user of a search engine. In general, given a search query by a user embodiments of the system and method discover and then recommend a list of searchable web sites. Embodiments of the system and method discover and recommend searchable web sites using client-side query behavior logs. A set of descriptive features is automatically extracted from the logs. In addition, embodiments of the system and method expand the initial search query by submitting the query to a general search engine and leveraging snippets from the search engine results. Embodiments of the system and method model a conditional probability of a searchable web site based on four components and the extracted descriptive features. A ranked list of recommended searchable web sites is obtained from the conditional probability and displayed to a user.
    • 一种可搜索的网站发现和推荐系统和方法,用于向搜索引擎的用户发现和推荐可搜索的网站。 通常,通过用户的系统和方法的实施例的搜索查询发现,然后推荐可搜索的网站的列表。 系统和方法的实施例使用客户端查询行为日志来发现和推荐可搜索的网站。 从日志中自动提取一组描述性特征。 此外,系统和方法的实施例通过将查询提交给一般搜索引擎并利用来自搜索引擎结果的片段来扩展初始搜索查询。 系统和方法的实施例基于四个组件和所提取的描述性特征建模可搜索的网站的条件概率。 推荐的可搜索网站的排名列表从条件概率获得并显示给用户。
