  • Publication number: 20200073953
    Abstract: A system stores records of different entity types and processes search queries to determine search results comprising records that match the search query. The system determines clusters of users based on feature vectors describing the users. A feature vector may be extracted from a hidden layer of a neural network. The system identifies a user that provided a search query and identifies a cluster of users matching the user. The system retrieves a set of weights for the cluster of users and uses the set of weights to rank the search results. The set of weights may represent relevance scores corresponding to various entity types. The system returns the ranked search results.

  • Publication number: 20190340256
    Abstract: A client device receives search queries and displays via a user interface, search results representing a set of the records based on the search queries. The client device monitors implicit user interactions with search query terms and records displayed in response to various search queries, for example, implicit user interactions representing movements of cursor on the portion of user interface displaying a particular record. The client device receives a partial search query. Partial search results representing a set of the records based on the partial search query are determined for display via the user interface. The relevance score for each record is determined based on implicit user interactions associated with past search queries. The partial search results are ranked based on the relevance scores and displayed by the client device according to the ranked order.

  • Publication number: 20190205465
    Abstract: A system stores objects of different types and processes search requests to determine search results matching the search criteria. For various objects stored in the system, the system tracks implicit user interactions and stores information of implicit user interactions. The implicit user interactions may be received in response to an object being presented as a search result or presented in response to other requests, for example, a request to browse objects or access the object otherwise. For each search result, the system determines a relevance score based on the stored information describing implicit user interactions. The relevance score of each entity type is used to rank search results for search requests. The system determines snippets for presenting to users along with search results based on implicit user interactions. The system also configures user interfaces for presenting search results based on implicit user interactions.

  • Publication number: 20190205472
    Abstract: A system stores objects of different types and allows search across the objects. The system receives search requests and processes them to determine search results matching the search criteria. For each of a plurality of search requests the system tracks implicit user interactions and stores information of implicit user interactions and associated search results and search requests. For each of a plurality of search results a relevance score is determined based on the stored information. The relevance score of each entity type is used to rank search results for search requests.

  • Patent number: 8533142
    Abstract: Systems, methods, and computer readable mediums. A method includes receiving an input expression including a set of options joined using logical operators. The method includes converting the input expression into an order string. The method includes receiving at least one rule that defines relationships between variants of different option families and receiving a configuration expression that specifies values for some but not all variants of the option families. The method includes producing a conjunctive normal form (CNF) order expression corresponding to the order string, at least one rule, and configuration expression. The method includes performing a partial solve of the order expression, the partial solve producing a result set that describes all possible configurations that correspond to the configuration expression.

  • Publication number: 20070232763
    Abstract: The invention provides polyester polymers suitable for production of monolayer and multilayer preforms and containers by a process of injection molding or co-injection molding and stretch blow molding technology for monolayer and multilayer containers. Containers of the invention not only have adequate CO2 barriers, but also have adequate O2 and UV barriers, high thermal stability, and burst strength to withstand tunnel pasteurization processes at about 60° C. for 20-30 minutes at 10 bar CO2 pressure for beer applications. There will further be no limitations due to humidity in respect of processing the resin/preforms and storage of preforms beyond what is required for normal PET. The polymers of the invention do not possess tie layer nor delamination problems and satisfy recycling criteria.
