Job posting standardization and deduplication

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. 描述用于对从第三方系统获得的未付费公开招聘进行标准化和重复数据删除的技术。通过社交网络服务从第三方系统获得未付费公开招聘。所述未付费公开招聘的职位和描述被标准化且组合成标准化未付费公开招聘。执行重复数据删除过程以防止所述标准化未付费公开招聘替代所述社交网络服务内的付费公开招聘，并且防止所述标准化未付费公开招聘替代所述社交网络服务内的更具权威性的未付费公开招聘。
