Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for correcting entity names. One method includes receiving texts and deriving a plurality of name-context pairs from the texts. The method further includes calculating a context consistency measure for each name-context pair and storing context-entity name data representing the name-context pairs. Another method includes identifying an entity name and one or more context terms from a query and generating candidate names for the entity name. The method further includes determining a score for each of the candidate names, selecting a number of top scoring candidate names, and using the selected candidate names to respond to the query.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, that are operable to identify a web page that is to be a basis for an advertisement creative; extract content to create an advertisement for serving in response to a request, extracting including extracting a title for the web page; create a title for the advertisement creative including computing a snippet of the title based on the request and the extracted title; combine a body with the advertising creative title; and combine with the body a uniform resource locator (URL) for a landing page that is to be associated with the advertisement creative.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, that are operable to identify a web page that is to be a basis for an advertisement creative; extract content associated with the web page to create an advertisement for serving in response to a request, extracting including abstracting content extracted so that the advertisement is not specifically descriptive of the web page; create a title for the advertisement; combine a body with the title; and combine with the body a uniform resource locator (URL) for a landing page that is to be associated with the advertisement creative.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, that are operable to index a plurality of commercial landing web pages in a database using queries previously resolved to the commercial landing pages where each entry in the database includes at least one query and a pointer to a commercial landing web page. A query can be received. The query can be processed by one or more processors including identifying a relevant commercial landing web page using the query. An advertisement creative can be generated from the relevant commercial landing web page.
