Abstract: In an embodiment, a computer system is configured to receive, from a client computer, a request with one or more values; determine, based on the one or more values, whether the request is from a platform-specific application compiled for a first computer platform; determine, based on the one or more values, whether the platform-specific application is being executed within an emulator being executed by a second computer platform, wherein the second computer platform is different than the first computer platform.

Abstract: In some implementations, a computer system for obfuscating text in an electronic document can include an analysis module, a font data repository, a re-coding module, and a data interface. The analysis module is operable to identify strings of text from an electronic document. The font data repository can include one or more character maps that correlate, for each character map in the one or more character maps, a first set of characters with a respective different second set of characters. The re-coding module can generate a re-coded document by re-mapping, using a particular one of the one or more character maps, the identified strings of text into corresponding obfuscated strings of text, and by replacing the identified strings of text with the corresponding obfuscated strings of text from the electronic document. The data interface can transmit the re-coded document to a client computing device.

Abstract: A system indirectly infers concepts associated with a document. The concepts may be indirectly inferred based on information that does not include characteristics of the document, such as the characteristics that include a textual content of the document not associated with links included in the document, a domain of the document, and the document's Uniform Resource Locator (URL). The system may label the inferred concepts as useful to an audience of the document.

Abstract: Content owners (e.g., Website publishers) are provided with a simple mechanism to automatically summarize and display information (news, images, maps, etc.) related to inferred interests of a user or users visiting their Website. The targeting can driven by a variety of mechanisms including, for example, an automated contextual understanding of the content of the Web page, profile-based information derived from personal data supplied by, or inferred from actions by, the user visiting the Website, location-targeted information (e.g., inferred by the Website visitor's current geography), etc. “Related Content Units” may be used to help content owners render useful, related, content by allowing for a variety of targeting methods to gather related pieces of Internet content and present them integrated into an HTML iFrame or a JavaScript/XML feed which can be easily integrated by the Website publisher onto the Web pages of their Website.

Abstract: One or more keywords associated with a first content item are identified. Restricted terms are identified. One or more of the one or more keywords are selected as a link, wherein the link does not contain the restricted terms.

Abstract: Techniques for determining location-based commercial information are described The techniques include receiving a request for an advertisement to be presented together with content provided over a delivery network to a recipient, performing a process to identify advertisement information to be presented based on the content, and if advertisement information is not identified by the process, identifying commercial information to be presented based an geographic location of the recipient and communicating over the delivery network, the identified commercial information to the recipient.

Abstract: Sponsored message placements are determined by (a) estimating a number of payable actions for candidate sponsored messages for a publication, (b) accepting batch mode distribution constraints of the publication and budget constraints of sponsors of the sponsored messages, and (c) selecting sponsored messages for the publication, from the set of candidate sponsored messages, using the estimated number of payable actions of the candidate sponsored messages, the batch mode distribution constraints, and the budget constraints, such that sponsored message placement revenue is increased. Each batch of the publication may then be published including the selected set of sponsored messages.
