Abstract: A method includes sequentially generating fragment records for a user device according to fragment generation rules specifying that each subsequent fragment record be generated for user device events that occur within a defined period of time. Each fragment record includes event data for a series of user device events and includes a fragment ID generated using a non-deterministic ID generation algorithm. The method includes generating an ID-fragment record associating a chain ID with the fragment IDs. The chain ID is associated with device IDs that identify the user device. The method includes removing associations between the chain ID and fragment IDs according to removal parameters indicating that associations be removed based on an age of the fragment records. The method includes generating at least one of search results and advertisements for the user device based on the event data in the fragment records that remain associated with the chain ID.

Abstract: A method includes receiving a request from a user device accessing a webpage, the request including a webpage uniform resource locator (URL) and a user device identifier. The method includes retrieving a list of events associated with the user device based on the device identifier. The method further includes retrieving sets of rules. Each set of rules indicates events and URLs that satisfy the set of rules. Each set of rules is associated with a template that includes link rendering data for rendering a link on the user device. The method includes identifying a set of rules that is satisfied by the received URL and events, transmitting link rendering data associated with the identified set of rules to the user device, and transmitting link routing data to the user device. The link routing data is configured to route the user device to an application state corresponding to the webpage.

Abstract: A method includes generating vertical-specific (VS) records from data sources. Each VS record includes a vertical identifier and a set of VS data fields. The method further comprises generating, for each VS record, an entity partial (EP) record that includes EP data fields populated from the VS data fields. The EP data fields include an entity ID that indicates an entity for the EP record, a source data field that identifies a data source, and an EP searchable data field including data that is descriptive of the entity. The method further comprises generating a search record for each entity ID by combining data from EP records. The data from the EP records is combined based on the source data included in the EP records. Each search record includes a search record searchable data field that includes data from one or more of the EP searchable data fields.

Abstract: A user device stores a local application including initial search records and an initial search function. Each initial search record includes an application link that opens an application page and search data that describes the application page. The initial search function is configured to select from the initial search records. The user device executes the local application to request and receive search update data from a remote system. The search update data includes updated search records and an updated search function. The user device updates the initial search records and the initial search function with the updated search records and the updated search function. The user device receives a search query from a requesting application, selects a set of updated search records based on the search query and the updated search function, and provides a response to the requesting application including application links from the set of updated search records.

Abstract: A contextual deep linking server receives a request associated with a valid contextual deep link from a client device, the contextual deep link associated with link data indicating a particular configuration of an application. The server also receives, after determining that the client device has stored a previously generated fingerprint, stored contextual information for the client device identified by a locally stored fingerprint that matches the previously generated fingerprint. The server then generates, after determining that the client device does not have the previously generated fingerprint, a unique fingerprint of the client device based on a plurality of characteristics of the client device and determining contextual information of the request based on a characteristic of the client device. The server also transmits a response to the client device that is selected based on the contextual information of the client device such that the response is operable on the client device.
