Methods and apparatus related to identifying authorship of Internet content. Some implementations are directed to methods and apparatus for identifying a content submission form on a webpage, recognizing submission of content by a user via the content submission form, and transmitting verification data in response to submission of the content by the user. The verification data may include content data indicative of at least some of the content submitted for publication via the content submission form.

Systems and methods related to identifying authorship of internet content

Systems and methods for identifying inadequate search content are provided. Inadequate search content, for example, can be identified based on statistics associated with the search queries related to the content.

Identifying inadequate search content

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for privacy protection. In one aspect, a method includes accessing personally identifiable information (PII) type definitions that characterize PII types; identifying PII type information included in content of a web page, the PII type information being information matching at least one PII type definition; identifying secondary information included in the content of the web page, the secondary information being information that is predefined as being associated with PII type information; determining a risk score from the PII type information and the secondary information; and classifying the web page as a personal information exposure risk if the risk score meets a confidentiality threshold, wherein the personal information exposure risk is indicative of the web page including personally identifiable information.

Personally identifiable information detection

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating activity signatures and detecting activity replays. In one aspect, a method includes accessing activity data first and second activity sequences; generating a first activity sequence signature from the first activity sequence, and generating, for each second activity sequence, a respective second activity sequence signature from the second activity sequence; for each second activity sequence, determining a similarity measure that is a measure of similarity of the first activity sequence to the second activity sequence from the signatures; for each second activity sequence having a similarity measure that meets a threshold, determining that a security violation occurred during the second user session of the second activity sequence; and for each second activity sequence having a similarity measure that does not meet the threshold, determining that a security violation did not occur during the second user session.

Activity signatures and activity replay detection

A spam detector accesses a message body of an email, extracts one or more features of a return path from the message body, and uses the extracted features to detect the return path for a user to respond to the email. The return path may include a postal address, and the extracted feature may comprise one or more of a complete or partial street name, city name, state name, country name, street number address, postal code, designations for post office box, and post office box number.

Methods and apparatus for detecting spam messages in an email system

Methods, systems, and apparatus, including computer program products, for testing web search scoring functions. A query is received. A first and a second scoring function are selected by receiving search results responsive to the query; applying candidate scoring functions to the search results to determine scores for the search results for each candidate scoring function; identifying pairs of the candidate scoring functions, and calculating a diversity score for each of the pairs. A pair of candidate scoring functions is chosen from the one or more pairs of candidate scoring functions based on the diversity scores, and the alpha function is selected as the first scoring function and the beta function is selected as the second scoring function. The plurality of search results are presented in an order according to scores from the first scoring function and are presented in an order according to scores from the second scoring function.

Framework for evaluating web search scoring functions

A method of processing documents is described. The method includes the operation of receiving a document in a search engine crawler. The document includes an embedded first link tag. The first link tag includes one or more information pairs. A respective information pair includes a respective parameter and a corresponding value. The parameters in the one or more information pairs may correspond to content at one or more content locations or one or more document locations. The method also includes selecting a method of processing content associated with the first link tag in accordance with one or more of the information pairs.

Embedded communication of link information

When a website has a number of equivalent domain names including a preferred domain name, the locator for a document in the website can be rewritten using the preferred domain name before indexing the document, according to certain embodiments. According to certain embodiments, a user interface is provided to allow a user to specify the preferred domain name for a website for which the user is a verified owner.

System and method for managing multiple domain names for a website in a website indexing system

When a website has a number of equivalent domain names including a preferred domain name, the URL for a document in the website can be rewritten using the preferred domain name before indexing the document, according to certain embodiments. According to certain embodiments, a user interface is provided to allow a user to specify the preferred domain name for a website for which the user is a verified owner.
