Abstract: Content management systems are implemented according to a multitenant architecture by which software and its supporting architecture serves multiple customers of a service. Each tenant may be given a share of the application's data, configuration, user management, and other aspects of the application. Each tenant's data is isolated and typically remains invisible to other tenants so that tenants do not share or see each other's data. Embodiments described herein provide mechanisms by which a tenant can delegate administrator rights to an external user such that the external user can grant other users access to the tenant's content while the tenant controls the level of access that is provided to the external users.

Abstract: Described herein is a technique for mapping the raw text of a job title of an online job posting to an entity embedding, associated with an entity or entry of a title taxonomy. The raw text of the job title is first encoded to generate a multilingual word embedding in a multilingual word embedding space. Then, the vector representation of the job title, as represented in the multilingual word embedding space is translated, using a neural network, to a vector representation of the job title in the entity embedding space. Finally, a nearest neighbor search is performed to identify an entity embedding associated with an entity or entry in the title taxonomy that has a vector representation that is closest in distance to the vector output by the neural network.
