摘要: A classification system trains a classifier to classify blocks of the web page into various classifications of the function of the block. The classification system trains a classifier using training web pages. To train a classifier, the classification system identifies the blocks of the training web pages, generates feature vectors for the blocks that include a linguistic feature, and inputs classification labels for each block. The classification system learns the coefficients of the classifier using any of a variety of machine learning techniques. The classification system can then use the classifier to classify blocks of web pages.

摘要: A method and system for identifying locations associated with a web resource is provided. The location system identifies three different types of geographic locations: a provider location, a content location, and a serving location. A provider location identifies the geographic location of the entity that provides the web resource. A content location identifies the geographic location that is the subject of the web resource. A serving location identifies the geographic scope that the web page reaches. An application can select to use the type of location that is of particular interest.

摘要: A method and system for generating a hybrid index for indexing objects based on location and keyword attributes and performing location-based searching is provided. A search system performs a location-based search using a hybrid index that indexes both location and keyword attributes of objects. The search system generates the hybrid index either using the location attribute as the primary index or the keyword attribute as the primary index. When the location attribute is the primary index, the keyword attribute is the secondary index, and vice versa. To generate the hybrid index, the search system identifies the values for the keyword and location attributes of each object. The search system generates the primary index to map each value of a first attribute to a secondary index. The search system thus generates, for each value of the first attribute, a secondary index to map values of a second attribute to objects that have the associated values of the first and second attributes. The search system then uses the hybrid index to perform location-based searching.
摘要翻译: 提供了一种用于基于位置和关键字属性生成用于索引对象的混合索引并执行基于位置的搜索的方法和系统。 搜索系统使用索引对象的位置和关键字属性的混合索引来执行基于位置的搜索。 搜索系统使用location属性作为主索引或keyword属性作为主索引来生成混合索引。 当location属性是主索引时,关键字属性是辅助索引,反之亦然。 为了生成混合索引,搜索系统识别每个对象的关键字和位置属性的值。 搜索系统生成主索引以将第一个属性的每个值映射到次要索引。 因此,搜索系统为第一属性的每个值生成辅助索引,以将第二属性的值映射到具有第一和第二属性的相关联值的对象。 然后,搜索系统使用混合索引来执行基于位置的搜索。

摘要: Mining geographic knowledge using a location aware topic model is provided. A location system estimates topics and locations associated with documents based on a location aware topic (“LAT”) model. The location system generates the model from a collection of documents that are labeled with their associated locations. The location system generates collection level parameters based on an LDA-style model. To generate the collection level parameters, the location system estimates probabilities of latent topics, locations, and words of the collection. After the model is generated, the location system uses the collection level parameters to estimate probabilities of topics and locations being associated with target documents.

摘要: A method and system for providing location-based advertisements to requesting devices is provided. An advertisement system aggregates advertisements by collecting advertisements from multiple advertisement sources, extracting data from the collected advertisements, and storing the extracted data in a common format. After aggregating the advertisements, the advertisement system transforms each advertisement into multiple advertisement formats that are specific to protocols supported by the various device types. When the advertisement system receives queries for advertisements, it identifies matching advertisements and ranks them based on a location. The advertisement system then selects an advertisement format that is appropriate for the requesting device.

摘要: An exemplary system includes a browser to browse a web page based on a web page definition having a slicing tree defining an arrangement of rectangular regions in the web page. The web page definition can include parametric data describing adaptability parameters associated with a rectangular region. A rendering module renders an adapted web page based on the web page definition, and a proxy module generates an intermediary adapted web page definition. A method includes rendering the web page according to a slicing tree and block property data in an associated web page definition. The method may include determining a set of unsummarized blocks that maximize information fidelity.

摘要: A method and system for searching for content relating to a target or query image by identifying duplicate images with associated content is provided. An image search system identifies visual parts of objects within the target image based on analysis of two or more versions of the target image. The image search system identifies visual parts based on analysis of the versions. The image search system then identifies images of an image database that have visual parts that are similar to the visual parts of the target image. The image search system may rank the identified images based on their likelihood of being duplicates of the target image and provide their associated content as the search result ordered according to the ranking of the images.

摘要: A method and system for generating a search request from a multimodal query that includes a query image and query text is provided. The multimodal query system identifies images of a collection that are textually related to the query image based on similarity between words associated with each image and the query text. The multimodal query system then selects those images of the identified images that are visually related to the query image. The multimodal query system may formulate a search request based on keywords of web pages that contain the selected images and submit that search request to a search engine service.
