Systems and methods are provided for receiving at least a first query color, and searching an electronic catalog including a plurality of product images for the first query color to determine a similarity measure between the first query color and a product image of a plurality of product images. The similarity measure may be determined by determining a Euclidean distance between values in a three-dimensional color space for the first query color and a target color of the product image, and determining the similarity measure between the query color and the product image by determining a sum of the similarity measures from all target colors on the product image, weighted by the coverage of each target color. The search results may be transmitted based on the searching of the electronic catalog including the plurality of product images for the first query color.

The present disclosure relates to systems and methods for improved vehicle transaction platforms. An example method may include receiving, by a vehicle transaction platform, a search request for vehicles from a user device associated with a first user account. The example method may also include receiving identifying information associated with the user account, wherein at least a portion of the identifying information is received from a third party. The example method may also include identifying, based on the identifying information, a predetermined search pattern, wherein the predetermined search pattern was generated based on a prior search request associated with a second user account and identifying information associated with the second user account. The example method may also include generating, based on the predetermined search pattern and the search request, a user interface configured to present a set of vehicles associated with the predetermined search pattern, wherein a presentation of a first vehicle of the set of vehicles includes financial acquisition terms customized based on the predetermined search pattern.

A system includes: a profile repository containing, for a client identifier, client attributes including an account balance defined in a first exchange medium, and an auxiliary classification attribute; a response generator to receive a request containing search parameters from a client device corresponding to the client identifier, and, synchronously with the request, to: obtain, based on the search parameters, an item identifier and an item cost in a second exchange medium; select, based on the auxiliary classification attribute, a conversion factor between the first and second exchange media; and send a response to the client device, the response containing the item identifier, the item cost, and a converted item cost in the first exchange medium, according to the conversion factor; and a classifier to, asynchronously with the request, generate an updated auxiliary classification attribute, and replace the auxiliary classification attribute in the repository with the updated auxiliary classification attribute.

Generating a printable inhalant solution may include selecting identifiers for one or more identified chemicals and creating, for each identified chemical, a chemical specification that includes at least a quantity of the chemical. The chemical specifications in the aggregate may include a chemical signature of the selected identified chemicals. Further, a printable solution may be mechanically printed onto a predetermined flammable base substrate.

In remotely rendering chemical signatures, a remote request received from a user comprises a requesting user identifier, a substrate specification, and a chemical signature. The chemical signature includes identifiers for one or more chemicals comprising a selected set of chemicals, and for each identified chemical at least a quantity of the selected set of chemicals. The received remote request is directed to a chemical printer that prints chemicals on the substrate based at least on the chemical signature. The printed substrate may be tagged with a predetermined digital tag format based at least on the requesting user identifier.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing chemical signatures are disclosed. In one aspect, a method includes the actions of receiving an original chemical signature, and an originating user identifier, the original chemical signature comprised of identifiers for one or more chemicals comprising a selected set of chemicals, and for each identified chemical at least a quantity of the selected set of chemicals. Responsive to the receiving of the original chemical signature, the actions further include generating an original hash based on at least a part of the original chemical signature and the originating user identifier. The actions further include storing on a distributed ledger the generated hash. Via at least one rule from a rules engine, the actions further include calculating an original attribution value associated with the originating user identifier.

Methods and systems to build containers of uncategorized items are described. In some example embodiments, the methods and systems collect information from titles of items available for purchase within a network-based publication system, generate a title for a container of uncategorized items available for purchase within the network-based publication system that is based on the collected information, and associate two or more uncategorized items available for purchase within the network-based publication system to the container based on a comparison of titles of the two or more uncategorized items and the generated title for the container of uncategorized items.

A system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for enhancing and personalizing an interactive marketplace. The systems and methods provided herein may allow a user to receive search results that are tailored to the user's personal preferences based on social and purchasing information known about the user. In addition, the systems and methods provided herein may provide shipping updates to a buyer that include a personalized message based on location information provided by the package being shipped. In addition, the systems and methods provided herein allow merchants to provide incentives and rewards for shoppers by participating in interactive shopping games.

Certain example embodiments relate to techniques generating a database of virtual families for real-time generation of part numbers for configurable products. For instance, certain example embodiments may include receiving a search request for part numbers and determining virtual families including entities matching the search request. The number of matching products matching the search request and the part numbers may be determined based on the virtual families and the independent groups stored in the virtual families that match the search request. The part numbers may be determined based on allowed characters, number and/or symbols for the part number positions defined in the independent groups of the virtual families including the entities matching the one or more configurable properties of the user input search request. Facet counts for the configurable product may also be determined based on the results of the user input search request.

Processing inputs to electronic list systems. Receiving, from a user device, a user input. Parsing the received user input for a minimum set of product data for querying a shopping service. Upon parsing a minimum set of product data for querying a shopping service, querying at least one shopping service using the parsed data. Receiving, from at least one queried shopping service, at least one product description responsive to the query. Presenting, via the user device, each received at least one product description to the user.
