摘要： A client application installed on end user computers generates metadata from the content of web pages visited by end users and provides the metadata to a search engine. When an end user visits a web page, the end user's computer downloads and displays the web page to the end user. The client application may simultaneously access the web page content and generate this metadata in the form of a content signature of the web page from the web page content. The client application then provides the content signature to a search engine. The search engine may employ content signatures to identify new web pages to crawl and index. Additionally, the search engine may employ content signatures to identify changes to web pages and determine the crawl frequency of web pages.

摘要： Methods, systems, and computer-storage media for improving the freshness, or the apparent freshness, of search results are described. In an embodiment, the first portion of search results presented on a search results page are based on responsiveness to the search query and a second portion of results describe only recently published documents that are responsive to the search query. In an embodiment, a more recent version of the document, which is not directly used to determine responsiveness, is used to build the caption for a search result. Another way to make search results appear fresh is to include a publication time within the search result caption. In one embodiment, the publication time is generated by calculating a point in time between when a document is first added to a search index and the previous time the search engine visited the site where the document was found.

摘要翻译： 描述了用于提高搜索结果的新鲜度或表观新鲜度的方法，系统和计算机存储介质。 在一个实施例中，在搜索结果页面上呈现的搜索结果的第一部分基于对搜索查询的响应，并且结果的第二部分仅描述响应于搜索查询的最近发布的文档。 在一个实施例中，使用不直接用于确定响应性的文档的更新版本来构建搜索结果的标题。 使搜索结果显示新鲜的另一种方法是在搜索结果标题中包含发布时间。 在一个实施例中，发布时间是通过计算文档首次添加到搜索索引的时间点与搜索引擎访问该文档所在的站点的之前的时间点来生成的。

摘要： Methods, systems, and media are provided for delivering clustered search results for recent and non-recent events by maintaining the identification (ID) numbers of the respective clustered documents beyond the “fresh” life span of the clustered documents. When clusters are formed according to similar content, an ID number and associated attributes are assigned to each of the clusters. This provides a mechanism to track and retrieve the respective clusters for subsequent delivery of search results. The respective ID numbers of the clusters are maintained, even after the documents are no longer considered “fresh.” These similar-content clusters are further subdivided according to publication date. This provides individual subdivided clusters for similar content events that occurred at different time spans, which are delivered along with individual non-clustered search results in a SERP.

摘要翻译： 提供了方法，系统和媒体，用于通过维护相应聚集文档的识别（ID）数字超出聚集文档的“新鲜”寿命，来传递最近和非近期事件的群集搜索结果。 当根据类似内容形成簇时，将ID号和相关属性分配给每个簇。 这提供了跟踪和检索相应集群以用于随后传送搜索结果的机制。 即使文件不再被认为是“新鲜”，集群的各自的ID号也被维护。这些类似内容的集群根据出版日期进一步细分。 这提供了用于在不同时间跨度发生的类似内容事件的单独的细分簇，它们与SERP中的各个非聚集搜索结果一起传送。

摘要： Methods and systems for determining an adaptive crawl rate for a Web crawler based on historical publication data from a Web source are provided. A frequency of publication of the Web source is determined over a specified period of time, and an adaptive crawl rate is calculated using the frequency of publication. The Web crawler is then deployed at the calculated adaptive crawl rate.

摘要： Methods, systems, and computer-readable media are provided for updating a search index with new uniform resource locators (URLs) and spiking URLs with increased user interest. History data, provided from browser applications residing on users' computers that indicate URLs accessed by the users, is parsed to identify new/previously unknown URLs. The history data also indicates URLs in which there is increased interest based on a number of recent hits as compared to an average number of hits determined over time. Author postings of new URLs to social networking sites and a quality rating of the authors may also be used to identify and filter new URLs. Search indexes are updated with the new and spiking URL data. As such, lag time between posting of new URLs and spiking of URL interest and inclusion of this data in a search index is greatly decreased.

摘要： Methods, systems, and computer-readable media are provided for updating a search index with new uniform resource locators (URLs) and with metadata for new and known URLs. Data associated with communications made by users using a social network is received. The communications include a URL therein that a user has shared, posted, or otherwise communicated to one or more other users using the social network. When the URL is not found in a search index it is identified as a new URL and is added to the search index. A measure of a trending interest, or virality, of the URL is determined from the data. The determined virality is associated with the URL in a search index as metadata. The virality is useable to inform a ranking of the URL against a plurality of other URLs for identification and presentation as a search result in a search engine results page.

摘要： Systems and methods for applying user behavior data to improve search query result ranking are provided. Upon receiving an update file indicating that recent, significant user behavior data is available for a document associated with an inverted index, the update file is published periodically and frequently to an index server. After filtering out the relevant update information from the update file, the index server extracts identifiers of the documents having the associated user behavior data. The update file and the identifier of the documents are utilized to update an in-memory index containing representations of metadata indicative of the user behavior. The in-memory index is continuously updated and utilized to serve search query results in response to user search queries. Search query results from the in-memory index are ranked using the user behavior data prior to serving. Thus, results associated with recent, significant user-behavior metadata receive prominent placement on the search results page.
