Abstract: Techniques for standardizing and deduplicating unpaid job postings obtained from third-party systems are described. An unpaid job posting is obtained by a social networking service from a third-party system. The title and description of the unpaid job posting are standardized and combined into a standardized unpaid job posting. A deduplication process is performed to prevent the standardized unpaid job posting from replacing a paid job posting within the social networking service, and to prevent the standardized unpaid job posting from replacing a more authoritative, unpaid job posting within the social networking service.

Abstract: User privacy is protected by preventing certain unsafe search queries from being associated with the user when saved by a search engine. When an unsafe query is detected, the unsafe query is submitted to a proxy service, and the proxy service submits the query to a search engine preventing the query from being associated with the user. The user receives the search results from the proxy service. Query filtering only allows queries to be submitted directly to the search engine that do not provide personal information or information which may infer an undesirable trend when taken in aggregate with other submitted queries by that user.
