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.

Abstract: Disclosed is a multi-dimensional analysis method for a tripping risk of a whole transmission line due to a lightning shielding failure. A quantity of thunderstorm days, a tower size, a terrain proportion, an altitude, and insulation configuration data are collected for a transmission line for which a tripping risk due to a lightning shielding failure needs to be analyzed, and a striking distance, an exposure distance, a lightning resisting level of the line after altitude factor correction, and a lightning shielding failure risk of a single-base tower are calculated in turn. Characteristics of a lightning shielding failure under different nominal heights, quantities of thunderstorm days, and terrains are studied. Representative combination conditions are selected to calculate a tripping risk of a typical tower due to the lightning shielding failure. A weight coefficient is extracted, to calculate a tripping risk of the whole line due to the lightning shielding failure.

Abstract: Techniques and solutions are provided for searching for documents upstream, downstream, or both upstream and downstream of a given document, and providing information about relationships between documents in the results. To help users understand relationships between documents, different “voices” can be used in a result display, such as an “active voice” being used for an upstream search and a “passive voice” being used for a downstream search. If desired, results can be limited or filtered, such as limiting a search to a particular relationship type or types, or providing a limit to an amount of indirection between documents. Disclosed techniques can provide more useful information about a document flow, and can reduce computing resources used in generating such displays.
