    摘要: This disclosure provides systems and methods for determining a classification model for a secondary language different from a primary language. A social networking server is configured to obtain primary language content written in a first spoken language and secondary language content written in a second spoken language. The social networking server further obtains a machine translation of the primary language content. The social networking server then determines an initial language model from the machine translation. The social networking further determines a language model perturbation using the initial language model, where the language model perturbation accounts for a difference between the machine translation and the secondary language content. The social networking server also determines a classification model from the initial language model and the language model perturbation, which is then applied to a plurality of comments associated with an item of interest provided by a social networking service.

    摘要: A method is provided. The method comprises receiving a search query that is part of a search conversation, the search query in an unstructured format; identifying a first list of facets with a first list of associated values from the search query; deriving a second list of facets with a second list of associated values from the first list of facets based on a context of the search query within the search conversation; generating a database query based on the second list of facets with the second list of associated values; causing a database search with the database query; transmitting a search result of the database search to a sender of the search query, wherein the method is performed by one or more computing devices.

    摘要: Hybrid classification system and method are described. The method commences when an input detector detects a raw input string that represents a value of a category in a member profile maintained by the on-line social network. The machine learning classifier derives a standardized value corresponding to the raw input string. The trigger module provides the raw input string to the correcting filter. The correcting filter determines a corrected standardized value corresponding to the raw input string based on the raw input string and a corrective rule. The label module then identifies the member profile as associate with the corrected standardized value.

    摘要: A method is provided. The method comprises receiving, from a user device, a current search query that is in an unstructured format; after receiving the current search query from the user device, retrieving a corresponding current list of facets with a current list of associated values and a context of the current search query, the context comprising a previous search query from the user device and a corresponding previous list of facets with a previous list of associated values; determining a group of actions on one or more of the current list of facets with the current list of associated values and the previous list of facets with the previous list of associated values based on the current search query; creating an updated list of facets with an updated list of associated values based on the group of actions; generating a database query based on the updated list of facets with the updated list of associated values; causing a database search with the database query; transmitting a search result of the database search to the user device, wherein the method is performed by one or more computing devices.
