  • Publication number: 20240078477
    Abstract: A method, a computer-readable medium, and an apparatus for transport service are provided. The apparatus may receive a plurality of transport service transactions associated with a point of interest entity. For each transport service transaction, the apparatus may determine a transport service location at which the transport service transaction is executed. The apparatus may cluster the transport service locations determined for the plurality of transport service transactions. The apparatus may determine one or more candidate transport service locations for the point of interest entity based on the clustering. The apparatus may provide the one or more candidate transport service locations to a client or a service provider associated with a transport service transaction that is to be executed at the point of interest entity.

  • Publication number: 20230397010
    Abstract: Aspects concern a server computer for verifying a location of a user device including a memory interface connected to a memory device that stores a database including verification and gathering questions, wherein each question of the verification and gathering questions is associated with a location, the database including an answer to each verification question and not including an answer to each gathering question; and a processing unit configured to: receive location data representing the location of the user device; select a verification question and a gathering question associated with the location of the user device; transmit the verification question and the gathering question to the user device and receive an answer to each of the verification and gathering question from the user device; if the answer provided by the user device to the verification question corresponds to the answer included in the database, verify the location of the user device.

  • Publication number: 20230306004
    Abstract: An automated computer implemented method of deduplicating point of interest of computer implemented database including: standardizing data of a pair of records, wherein equivalent words with different spelling may be normalized to a single spelling; classifying the pair of records into a category of pre-defined address categories; carrying out a category specific determination of non-duplicate and failing to determine that the pair of records may be a category specific non-duplicate; tokenizing the data of the pair of records into a pair of tokenized records; determining that core words of the pair of records are linked by computing scores of cross information and distance; and determining whether the scores pass a pre-determined threshold. An aspect of the disclosure relates to an electronic data processing system, a data processing apparatus, a non-transitory computer-readable medium, and a computer executable code for deduplicating point of interest of computer implemented database.

  • Publication number: 20230119116
    Abstract: An apparatus and method for inferring optimal pick-up/drop-off locations for transport services use historical bookings data associated with past bookings, the past bookings having a pick-up or drop-off location within a defined geographical area. Each historical data instance for a booking includes a geographical data point recorded at a time of a pick-up/drop-off event within the geographical area. The historical data is processed to identify clusters of geographic data points having similar geographical locations. A quality indicator is determined and compared with a first threshold. If the quality indicator satisfies the first threshold, a cluster centroid for each cluster is designated as an optimal pick-up/drop-off location for the geographical area.

  • Patent number: 11488276
    Abstract: A processor device has a CPU cooperating with an input device and an output device, under control of stored instructions, and is arranged to receive service requests at the input device, assign service requests received in successive time periods to respective batches of requests; access stored service provider data to identify available service providers from among a pool of service providers; after completing the assignment of service requests to a batch, perform a matching process to endeavour to match each service request of the batch of requests to a service provider; and for each service provider to whom a match is made, output a notification of the respective potential match from the output device.

  • Publication number: 20210341299
    Abstract: Example embodiments relate generally to methods, systems, and devices for managing service providers and service requests. The method includes, for each identified geographical area, deriving a service request forecast and service provider forecast for a particular upcoming time period. The method includes, for each identified geographical area, determining whether the geographical area will be in an over-supply state during the particular upcoming time period. The method includes, for each identified geographical area determined to be in the over-supply state during the particular upcoming time period: determining a quantity M of available service providers; selecting at least M available service providers in the geographical area; and providing a notification to only the selected available service providers. Each notification may include a message to move out of the geographical area and into a particular location in another geographical area.
