Title: Computerized systems and methods for using artificial intelligence to generate product recommendations

Description:
TECHNICAL FIELD 
     The present disclosure generally relates to computerized systems and methods for using artificial intelligence (AI) to generate product recommendations. In particular, embodiments of the present disclosure relate to inventive and unconventional systems that may automatically modify a user interface element based on a user identifier and a product identifier associated with a query by generating a model to generate a list of recommended products. 
     BACKGROUND 
     Consumers often shop for and purchase various items online through computers and smart devices. These online shoppers often require more than one day to determine the best product for them to purchase. For example, many online shoppers may spend weeks researching and evaluating multiple products before purchasing the best product. However, the normal online shopping experience is hindered by online shopping engines that treat all customer sessions the same, regardless of how long a shopper has been deliberating products. For example, conventional online shopping engines may provide similar recommendations regardless of whether the shopper has been shopping for a product for one day or for fourteen days. 
     Millions of products are registered online by sellers every day. Sellers are required to select the correct category to which their product belongs when registering their products online for sale. However, many sellers do not select the correct category when registering their product. For example, a seller may incorrectly select the “Kid&#39;s Fashion” category when registering an infant onesie that belongs in the “Baby” category. Incorrect product categorization may severely reduce a consumer&#39;s user experience by prolonging the consumer&#39;s product search and by reducing the recommendation quality of the online platform. Furthermore, manually correcting the categorization of products is often difficult and time-consuming since tens of thousands of different categories may exist. A consumer&#39;s user experience would be significantly improved if the online platform automatically categorized products into their correct categories. 
     Online shopping engines that fail to account for a shopper&#39;s actions during a customer session for a product may severely reduce a shopper&#39;s user experience by prolonging the shopper&#39;s product search and by reducing the recommendation quality of the online platform. Furthermore, manually accounting for different customer sessions is difficult and time-consuming since many different shoppers with various customer sessions exist. A consumer&#39;s user experience would be significantly improved if the online platform automatically learned from consumers&#39; shopping behavior and customized product recommendations accordingly. 
     Therefore, there is a need for improved methods and systems for generating product recommendations so that consumers may quickly find and purchase products while online shopping.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several illustrative embodiments are described herein, modifications, adaptations and other implementations are possible. For example, substitutions, additions, or modifications may be made to the components and steps illustrated in the drawings, and the illustrative methods described herein may be modified by substituting, reordering, removing, or adding steps to the disclosed methods. Accordingly, the following detailed description is not limited to the disclosed embodiments and examples. Instead, the proper scope of the invention is defined by the appended claims. 
     Embodiments of the present disclosure are directed to systems and methods configured for AI-based product recommendation generation. The disclosed embodiments are capable of using a model to predict at least one recommended product based on the user identifier and the product identifier. For example, a product recommendation system may retrieve at least one query submitted by a user associated with a user identifier during a time span. The product recommendation system may use the model and attributes extracted from queries to determine a product category associated with the user identifier and a product identifier. 
     In some embodiments, the product recommendation system may generate a list of recommended products by calculating a similarity score for each product on a generated list of products. In some embodiments, the product recommendation system may calculate the similarity scores by assigning at least one weighted value to at least one factor. In some embodiments, the at least one factor may include historical user data of at least one of selecting a product on a webpage, adding a product to a cart on the webpage, or purchasing a product on the webpage. 
     In some embodiments, a user may interact with a user interface element associated with a webpage to sort the generated list of recommended products. For example, the product recommendation system may modify a user interface element so that the user may sort the generated list of recommended products by price, similarity score, sales volume, etc. In some embodiments, the product recommendation system may automatically modify the user interface element to display the generated list of recommended products by price, similarity score, sales volume, etc. 
     Referring to  FIG. 1A , a schematic block diagram  100  illustrating an exemplary embodiment of a system comprising computerized systems for communications enabling shipping, transportation, and logistics operations is shown. As illustrated in  FIG. 1A , system  100  may include a variety of systems, each of which may be connected to one another via one or more networks. The systems may also be connected to one another via a direct connection, for example, using a cable. The depicted systems include a shipment authority technology (SAT) system  101 , an external front end system  103 , an internal front end system  105 , a transportation system  107 , mobile devices  107 A,  107 B, and  107 C, seller portal  109 , shipment and order tracking (SOT) system  111 , fulfillment optimization (FO) system  113 , fulfillment messaging gateway (FMG)  115 , supply chain management (SCM) system  117 , warehouse management system  119 , mobile devices  119 A,  119 B, and  119 C (depicted as being inside of fulfillment center (FC)  200 ), 3 rd  party fulfillment systems  121 A,  121 B, and  121 C, fulfillment center authorization system (FC Auth)  123 , and labor management system (LMS)  125 . 
     SAT system  101 , in some embodiments, may be implemented as a computer system that monitors order status and delivery status. For example, SAT system  101  may determine whether an order is past its Promised Delivery Date (PDD) and may take appropriate action, including initiating a new order, reshipping the items in the non-delivered order, canceling the non-delivered order, initiating contact with the ordering customer, or the like. SAT system  101  may also monitor other data, including output (such as a number of packages shipped during a particular time period) and input (such as the number of empty cardboard boxes received for use in shipping). SAT system  101  may also act as a gateway between different devices in system  100 , enabling communication (e.g., using store-and-forward or other techniques) between devices such as external front end system  103  and FO system  113 . 
     External front end system  103 , in some embodiments, may be implemented as a computer system that enables external users to interact with one or more systems in system  100 . For example, in embodiments where system  100  enables the presentation of systems to enable users to place an order for an item, external front end system  103  may be implemented as a web server that receives search requests, presents item pages, and solicits payment information. For example, external front end system  103  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, external front end system  103  may run custom web server software designed to receive and process requests from external devices (e.g., mobile device  102 A or computer  102 B), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, external front end system  103  may include one or more of a web caching system, a database, a search system, or a payment system. In one aspect, external front end system  103  may comprise one or more of these systems, while in another aspect, external front end system  103  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     An illustrative set of steps, illustrated by  FIGS. 1B, 1C, 1D, and 1E , will help to describe some operations of external front end system  103 . External front end system  103  may receive information from systems or devices in system  100  for presentation and/or display. For example, external front end system  103  may host or provide one or more web pages, including a Search Result Page (SRP) (e.g.,  FIG. 1B ), a Single Detail Page (SDP) (e.g.,  FIG. 1C ), a Cart page (e.g.,  FIG. 1D ), or an Order page (e.g.,  FIG. 1E ). A user device (e.g., using mobile device  102 A or computer  102 B) may navigate to external front end system  103  and request a search by entering information into a search box. External front end system  103  may request information from one or more systems in system  100 . For example, external front end system  103  may request information from FO System  113  that satisfies the search request. External front end system  103  may also request and receive (from FO System  113 ) a Promised Delivery Date or “PDD” for each product included in the search results. The PDD, in some embodiments, may represent an estimate of when a package containing the product will arrive at the user&#39;s desired location or a date by which the product is promised to be delivered at the user&#39;s desired location if ordered within a particular period of time, for example, by the end of the day (11:59 PM). (PDD is discussed further below with respect to FO System  113 .) 
     External front end system  103  may prepare an SRP (e.g.,  FIG. 1B ) based on the information. The SRP may include information that satisfies the search request. For example, this may include pictures of products that satisfy the search request. The SRP may also include respective prices for each product, or information relating to enhanced delivery options for each product, PDD, weight, size, offers, discounts, or the like. External front end system  103  may send the SRP to the requesting user device (e.g., via a network). 
     A user device may then select a product from the SRP, e.g., by clicking or tapping a user interface, or using another input device, to select a product represented on the SRP. The user device may formulate a request for information on the selected product and send it to external front end system  103 . In response, external front end system  103  may request information related to the selected product. For example, the information may include additional information beyond that presented for a product on the respective SRP. This could include, for example, shelf life, country of origin, weight, size, number of items in package, handling instructions, or other information about the product. The information could also include recommendations for similar products (based on, for example, big data and/or machine learning analysis of customers who bought this product and at least one other product), answers to frequently asked questions, reviews from customers, manufacturer information, pictures, or the like. 
     External front end system  103  may prepare an SDP (Single Detail Page) (e.g.,  FIG. 1C ) based on the received product information. The SDP may also include other interactive elements such as a “Buy Now” button, a “Add to Cart” button, a quantity field, a picture of the item, or the like. The SDP may further include a list of sellers that offer the product. The list may be ordered based on the price each seller offers such that the seller that offers to sell the product at the lowest price may be listed at the top. The list may also be ordered based on the seller ranking such that the highest ranked seller may be listed at the top. The seller ranking may be formulated based on multiple factors, including, for example, the seller&#39;s past track record of meeting a promised PDD. External front end system  103  may deliver the SDP to the requesting user device (e.g., via a network). 
     The requesting user device may receive the SDP which lists the product information. Upon receiving the SDP, the user device may then interact with the SDP. For example, a user of the requesting user device may click or otherwise interact with a “Place in Cart” button on the SDP. This adds the product to a shopping cart associated with the user. The user device may transmit this request to add the product to the shopping cart to external front end system  103 . 
     External front end system  103  may generate a Cart page (e.g.,  FIG. 1D ). The Cart page, in some embodiments, lists the products that the user has added to a virtual “shopping cart.” A user device may request the Cart page by clicking on or otherwise interacting with an icon on the SRP, SDP, or other pages. The Cart page may, in some embodiments, list all products that the user has added to the shopping cart, as well as information about the products in the cart such as a quantity of each product, a price for each product per item, a price for each product based on an associated quantity, information regarding PDD, a delivery method, a shipping cost, user interface elements for modifying the products in the shopping cart (e.g., deletion or modification of a quantity), options for ordering other product or setting up periodic delivery of products, options for setting up interest payments, user interface elements for proceeding to purchase, or the like. A user at a user device may click on or otherwise interact with a user interface element (e.g., a button that reads “Buy Now”) to initiate the purchase of the product in the shopping cart. Upon doing so, the user device may transmit this request to initiate the purchase to external front end system  103 . 
     External front end system  103  may generate an Order page (e.g.,  FIG. 1E ) in response to receiving the request to initiate a purchase. The Order page, in some embodiments, re-lists the items from the shopping cart and requests input of payment and shipping information. For example, the Order page may include a section requesting information about the purchaser of the items in the shopping cart (e.g., name, address, e-mail address, phone number), information about the recipient (e.g., name, address, phone number, delivery information), shipping information (e.g., speed/method of delivery and/or pickup), payment information (e.g., credit card, bank transfer, check, stored credit), user interface elements to request a cash receipt (e.g., for tax purposes), or the like. External front end system  103  may send the Order page to the user device. 
     The user device may enter information on the Order page and click or otherwise interact with a user interface element that sends the information to external front end system  103 . From there, external front end system  103  may send the information to different systems in system  100  to enable the creation and processing of a new order with the products in the shopping cart. 
     In some embodiments, external front end system  103  may be further configured to enable sellers to transmit and receive information relating to orders. 
     Internal front end system  105 , in some embodiments, may be implemented as a computer system that enables internal users (e.g., employees of an organization that owns, operates, or leases system  100 ) to interact with one or more systems in system  100 . For example, in embodiments where system  100  enables the presentation of systems to enable users to place an order for an item, internal front end system  105  may be implemented as a web server that enables internal users to view diagnostic and statistical information about orders, modify item information, or review statistics relating to orders. For example, internal front end system  105  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, internal front end system  105  may run custom web server software designed to receive and process requests from systems or devices depicted in system  100  (as well as other devices not depicted), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, internal front end system  105  may include one or more of a web caching system, a database, a search system, a payment system, an analytics system, an order monitoring system, or the like. In one aspect, internal front end system  105  may comprise one or more of these systems, while in another aspect, internal front end system  105  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     Transportation system  107 , in some embodiments, may be implemented as a computer system that enables communication between systems or devices in system  100  and mobile devices  107 A- 107 C. Transportation system  107 , in some embodiments, may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like). For example, in some embodiments, mobile devices  107 A- 107 C may comprise devices operated by delivery workers. The delivery workers, who may be permanent, temporary, or shift employees, may utilize mobile devices  107 A- 107 C to effect delivery of packages containing the products ordered by users. For example, to deliver a package, the delivery worker may receive a notification on a mobile device indicating which package to deliver and where to deliver it. Upon arriving at the delivery location, the delivery worker may locate the package (e.g., in the back of a truck or in a crate of packages), scan or otherwise capture data associated with an identifier on the package (e.g., a barcode, an image, a text string, an RFID tag, or the like) using the mobile device, and deliver the package (e.g., by leaving it at a front door, leaving it with a security guard, handing it to the recipient, or the like). In some embodiments, the delivery worker may capture photo(s) of the package and/or may obtain a signature using the mobile device. The mobile device may send information to transportation system  107  including information about the delivery, including, for example, time, date, GPS location, photo(s), an identifier associated with the delivery worker, an identifier associated with the mobile device, or the like. Transportation system  107  may store this information in a database (not pictured) for access by other systems in system  100 . Transportation system  107  may, in some embodiments, use this information to prepare and send tracking data to other systems indicating the location of a particular package. 
     In some embodiments, certain users may use one kind of mobile device (e.g., permanent workers may use a specialized PDA with custom hardware such as a barcode scanner, stylus, and other devices) while other users may use other kinds of mobile devices (e.g., temporary or shift workers may utilize off-the-shelf mobile phones and/or smartphones). 
     In some embodiments, transportation system  107  may associate a user with each device. For example, transportation system  107  may store an association between a user (represented by, e.g., a user identifier, an employee identifier, or a phone number) and a mobile device (represented by, e.g., an International Mobile Equipment Identity (IMEI), an International Mobile Subscription Identifier (IMSI), a phone number, a Universal Unique Identifier (UUID), or a Globally Unique Identifier (GUID)). Transportation system  107  may use this association in conjunction with data received on deliveries to analyze data stored in the database in order to determine, among other things, a location of the worker, an efficiency of the worker, or a speed of the worker. 
     Seller portal  109 , in some embodiments, may be implemented as a computer system that enables sellers or other external entities to electronically communicate with one or more systems in system  100 . For example, a seller may utilize a computer system (not pictured) to upload or provide product information, order information, contact information, or the like, for products that the seller wishes to sell through system  100  using seller portal  109 . 
     Shipment and order tracking system  111 , in some embodiments, may be implemented as a computer system that receives, stores, and forwards information regarding the location of packages containing products ordered by customers (e.g., by a user using devices  102 A- 102 B). In some embodiments, shipment and order tracking system  111  may request or store information from web servers (not pictured) operated by shipping companies that deliver packages containing products ordered by customers. 
     In some embodiments, shipment and order tracking system  111  may request and store information from systems depicted in system  100 . For example, shipment and order tracking system  111  may request information from transportation system  107 . As discussed above, transportation system  107  may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like) that are associated with one or more of a user (e.g., a delivery worker) or a vehicle (e.g., a delivery truck). In some embodiments, shipment and order tracking system  111  may also request information from warehouse management system (WMS)  119  to determine the location of individual products inside of a fulfillment center (e.g., fulfillment center  200 ). Shipment and order tracking system  111  may request data from one or more of transportation system  107  or WMS  119 , process it, and present it to a device (e.g., user devices  102 A and  102 B) upon request. 
     Fulfillment optimization (FO) system  113 , in some embodiments, may be implemented as a computer system that stores information for customer orders from other systems (e.g., external front end system  103  and/or shipment and order tracking system  111 ). FO system  113  may also store information describing where particular items are held or stored. For example, certain items may be stored only in one fulfillment center, while certain other items may be stored in multiple fulfillment centers. In still other embodiments, certain fulfilment centers may be designed to store only a particular set of items (e.g., fresh produce or frozen products). FO system  113  stores this information as well as associated information (e.g., quantity, size, date of receipt, expiration date, etc.). 
     FO system  113  may also calculate a corresponding PDD (promised delivery date) for each product. The PDD, in some embodiments, may be based on one or more factors. For example, FO system  113  may calculate a PDD for a product based on a past demand for a product (e.g., how many times that product was ordered during a period of time), an expected demand for a product (e.g., how many customers are forecast to order the product during an upcoming period of time), a network-wide past demand indicating how many products were ordered during a period of time, a network-wide expected demand indicating how many products are expected to be ordered during an upcoming period of time, one or more counts of the product stored in each fulfillment center  200 , which fulfillment center stores each product, expected or current orders for that product, or the like. 
     In some embodiments, FO system  113  may determine a PDD for each product on a periodic basis (e.g., hourly) and store it in a database for retrieval or sending to other systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ). In other embodiments, FO system  113  may receive electronic requests from one or more systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ) and calculate the PDD on demand. 
     Fulfilment messaging gateway (FMG)  115 , in some embodiments, may be implemented as a computer system that receives a request or response in one format or protocol from one or more systems in system  100 , such as FO system  113 , converts it to another format or protocol, and forward it in the converted format or protocol to other systems, such as WMS  119  or 3 rd  party fulfillment systems  121 A,  121 B, or  121 C, and vice versa. 
     Supply chain management (SCM) system  117 , in some embodiments, may be implemented as a computer system that performs forecasting functions. For example, SCM system  117  may forecast a level of demand for a particular product based on, for example, based on a past demand for products, an expected demand for a product, a network-wide past demand, a network-wide expected demand, a count products stored in each fulfillment center  200 , expected or current orders for each product, or the like. In response to this forecasted level and the amount of each product across all fulfillment centers, SCM system  117  may generate one or more purchase orders to purchase and stock a sufficient quantity to satisfy the forecasted demand for a particular product. 
     Warehouse management system (WMS)  119 , in some embodiments, may be implemented as a computer system that monitors workflow. For example, WMS  119  may receive event data from individual devices (e.g., devices  107 A- 107 C or  119 A- 119 C) indicating discrete events. For example, WMS  119  may receive event data indicating the use of one of these devices to scan a package. As discussed below with respect to fulfillment center  200  and  FIG. 2 , during the fulfillment process, a package identifier (e.g., a barcode or RFID tag data) may be scanned or read by machines at particular stages (e.g., automated or handheld barcode scanners, RFID readers, high-speed cameras, devices such as tablet  119 A, mobile device/PDA  119 B, computer  119 C, or the like). WMS  119  may store each event indicating a scan or a read of a package identifier in a corresponding database (not pictured) along with the package identifier, a time, date, location, user identifier, or other information, and may provide this information to other systems (e.g., shipment and order tracking system  111 ). 
     WMS  119 , in some embodiments, may store information associating one or more devices (e.g., devices  107 A- 107 C or  119 A- 119 C) with one or more users associated with system  100 . For example, in some situations, a user (such as a part- or full-time employee) may be associated with a mobile device in that the user owns the mobile device (e.g., the mobile device is a smartphone). In other situations, a user may be associated with a mobile device in that the user is temporarily in custody of the mobile device (e.g., the user checked the mobile device out at the start of the day, will use it during the day, and will return it at the end of the day). 
     WMS  119 , in some embodiments, may maintain a work log for each user associated with system  100 . For example, WMS  119  may store information associated with each employee, including any assigned processes (e.g., unloading trucks, picking items from a pick zone, rebin wall work, packing items), a user identifier, a location (e.g., a floor or zone in a fulfillment center  200 ), a number of units moved through the system by the employee (e.g., number of items picked, number of items packed), an identifier associated with a device (e.g., devices  119 A- 119 C), or the like. In some embodiments, WMS  119  may receive check-in and check-out information from a timekeeping system, such as a timekeeping system operated on a device  119 A- 119 C. 
     3 rd  party fulfillment (3PL) systems  121 A- 121 C, in some embodiments, represent computer systems associated with third-party providers of logistics and products. For example, while some products are stored in fulfillment center  200  (as discussed below with respect to  FIG. 2 ), other products may be stored off-site, may be produced on demand, or may be otherwise unavailable for storage in fulfillment center  200 . 3PL systems  121 A- 121 C may be configured to receive orders from FO system  113  (e.g., through FMG  115 ) and may provide products and/or services (e.g., delivery or installation) to customers directly. In some embodiments, one or more of 3PL systems  121 A- 121 C may be part of system  100 , while in other embodiments, one or more of 3PL systems  121 A- 121 C may be outside of system  100  (e.g., owned or operated by a third-party provider). 
     Fulfillment Center Auth system (FC Auth)  123 , in some embodiments, may be implemented as a computer system with a variety of functions. For example, in some embodiments, FC Auth  123  may act as a single-sign on (SSO) service for one or more other systems in system  100 . For example, FC Auth  123  may enable a user to log in via internal front end system  105 , determine that the user has similar privileges to access resources at shipment and order tracking system  111 , and enable the user to access those privileges without requiring a second log in process. FC Auth  123 , in other embodiments, may enable users (e.g., employees) to associate themselves with a particular task. For example, some employees may not have an electronic device (such as devices  119 A- 119 C) and may instead move from task to task, and zone to zone, within a fulfillment center  200 , during the course of a day. FC Auth  123  may be configured to enable those employees to indicate what task they are performing and what zone they are in at different times of day. 
     Labor management system (LMS)  125 , in some embodiments, may be implemented as a computer system that stores attendance and overtime information for employees (including full-time and part-time employees). For example, LMS  125  may receive information from FC Auth  123 , WMS  119 , devices  119 A- 119 C, transportation system  107 , and/or devices  107 A- 107 C. 
     The particular configuration depicted in  FIG. 1A  is an example only. For example, while  FIG. 1A  depicts FC Auth system  123  connected to FO system  113 , not all embodiments require this particular configuration. Indeed, in some embodiments, the systems in system  100  may be connected to one another through one or more public or private networks, including the Internet, an Intranet, a WAN (Wide-Area Network), a MAN (Metropolitan-Area Network), a wireless network compliant with the IEEE 802.11a/b/g/n Standards, a leased line, or the like. In some embodiments, one or more of the systems in system  100  may be implemented as one or more virtual servers implemented at a data center, server farm, or the like. 
       FIG. 2  depicts a fulfillment center  200 . Fulfillment center  200  is an example of a physical location that stores items for shipping to customers when ordered. Fulfillment center (FC)  200  may be divided into multiple zones, each of which are depicted in  FIG. 2 . These “zones,” in some embodiments, may be thought of as virtual divisions between different stages of a process of receiving items, storing the items, retrieving the items, and shipping the items. So while the “zones” are depicted in  FIG. 2 , other divisions of zones are possible, and the zones in  FIG. 2  may be omitted, duplicated, or modified in some embodiments. 
     Inbound zone  203  represents an area of FC  200  where items are received from sellers who wish to sell products using system  100  from  FIG. 1A . For example, a seller may deliver items  202 A and  202 B using truck  201 . Item  202 A may represent a single item large enough to occupy its own shipping pallet, while item  202 B may represent a set of items that are stacked together on the same pallet to save space. 
     A worker will receive the items in inbound zone  203  and may optionally check the items for damage and correctness using a computer system (not pictured). For example, the worker may use a computer system to compare the quantity of items  202 A and  202 B to an ordered quantity of items. If the quantity does not match, that worker may refuse one or more of items  202 A or  202 B. If the quantity does match, the worker may move those items (using, e.g., a dolly, a handtruck, a forklift, or manually) to buffer zone  205 . Buffer zone  205  may be a temporary storage area for items that are not currently needed in the picking zone, for example, because there is a high enough quantity of that item in the picking zone to satisfy forecasted demand. In some embodiments, forklifts  206  operate to move items around buffer zone  205  and between inbound zone  203  and drop zone  207 . If there is a need for items  202 A or  202 B in the picking zone (e.g., because of forecasted demand), a forklift may move items  202 A or  202 B to drop zone  207 . 
     Drop zone  207  may be an area of FC  200  that stores items before they are moved to picking zone  209 . A worker assigned to the picking task (a “picker”) may approach items  202 A and  202 B in the picking zone, scan a barcode for the picking zone, and scan barcodes associated with items  202 A and  202 B using a mobile device (e.g., device  119 B). The picker may then take the item to picking zone  209  (e.g., by placing it on a cart or carrying it). 
     Picking zone  209  may be an area of FC  200  where items  208  are stored on storage units  210 . In some embodiments, storage units  210  may comprise one or more of physical shelving, bookshelves, boxes, totes, refrigerators, freezers, cold stores, or the like. In some embodiments, picking zone  209  may be organized into multiple floors. In some embodiments, workers or machines may move items into picking zone  209  in multiple ways, including, for example, a forklift, an elevator, a conveyor belt, a cart, a handtruck, a dolly, an automated robot or device, or manually. For example, a picker may place items  202 A and  202 B on a handtruck or cart in drop zone  207  and walk items  202 A and  202 B to picking zone  209 . 
     A picker may receive an instruction to place (or “stow”) the items in particular spots in picking zone  209 , such as a particular space on a storage unit  210 . For example, a picker may scan item  202 A using a mobile device (e.g., device  119 B). The device may indicate where the picker should stow item  202 A, for example, using a system that indicate an aisle, shelf, and location. The device may then prompt the picker to scan a barcode at that location before stowing item  202 A in that location. The device may send (e.g., via a wireless network) data to a computer system such as WMS  119  in  FIG. 1A  indicating that item  202 A has been stowed at the location by the user using device  1198 . 
     Once a user places an order, a picker may receive an instruction on device  1198  to retrieve one or more items  208  from storage unit  210 . The picker may retrieve item  208 , scan a barcode on item  208 , and place it on transport mechanism  214 . While transport mechanism  214  is represented as a slide, in some embodiments, transport mechanism may be implemented as one or more of a conveyor belt, an elevator, a cart, a forklift, a handtruck, a dolly, a cart, or the like. Item  208  may then arrive at packing zone  211 . 
     Packing zone  211  may be an area of FC  200  where items are received from picking zone  209  and packed into boxes or bags for eventual shipping to customers. In packing zone  211 , a worker assigned to receiving items (a “rebin worker”) will receive item  208  from picking zone  209  and determine what order it corresponds to. For example, the rebin worker may use a device, such as computer  119 C, to scan a barcode on item  208 . Computer  119 C may indicate visually which order item  208  is associated with. This may include, for example, a space or “cell” on a wall  216  that corresponds to an order. Once the order is complete (e.g., because the cell contains all items for the order), the rebin worker may indicate to a packing worker (or “packer”) that the order is complete. The packer may retrieve the items from the cell and place them in a box or bag for shipping. The packer may then send the box or bag to a hub zone  213 , e.g., via forklift, cart, dolly, handtruck, conveyor belt, manually, or otherwise. 
     Hub zone  213  may be an area of FC  200  that receives all boxes or bags (“packages”) from packing zone  211 . Workers and/or machines in hub zone  213  may retrieve package  218  and determine which portion of a delivery area each package is intended to go to, and route the package to an appropriate camp zone  215 . For example, if the delivery area has two smaller sub-areas, packages will go to one of two camp zones  215 . In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Routing the package to camp zone  215  may comprise, for example, determining a portion of a geographical area that the package is destined for (e.g., based on a postal code) and determining a camp zone  215  associated with the portion of the geographical area. 
     Camp zone  215 , in some embodiments, may comprise one or more buildings, one or more physical spaces, or one or more areas, where packages are received from hub zone  213  for sorting into routes and/or sub-routes. In some embodiments, camp zone  215  is physically separate from FC  200  while in other embodiments camp zone  215  may form a part of FC  200 . 
     Workers and/or machines in camp zone  215  may determine which route and/or sub-route a package  220  should be associated with, for example, based on a comparison of the destination to an existing route and/or sub-route, a calculation of workload for each route and/or sub-route, the time of day, a shipping method, the cost to ship the package  220 , a PDD associated with the items in package  220 , or the like. In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Once package  220  is assigned to a particular route and/or sub-route, a worker and/or machine may move package  220  to be shipped. In exemplary  FIG. 2 , camp zone  215  includes a truck  222 , a car  226 , and delivery workers  224 A and  224 B. In some embodiments, truck  222  may be driven by delivery worker  224 A, where delivery worker  224 A is a full-time employee that delivers packages for FC  200  and truck  222  is owned, leased, or operated by the same company that owns, leases, or operates FC  200 . In some embodiments, car  226  may be driven by delivery worker  224 B, where delivery worker  224 B is a “flex” or occasional worker that is delivering on an as-needed basis (e.g., seasonally). Car  226  may be owned, leased, or operated by delivery worker  224 B.

Processors  332 ,  352 , or  362  may be one or more known processing devices, such as a microprocessor from the Pentium™ family manufactured by Intel™ or the Turion™ family manufactured by AMD™. Processors  332 ,  352 , or  362  may constitute a single core or multiple core processor that executes parallel processes simultaneously. For example, processors  332 ,  352 , or  362  may use logical processors to simultaneously execute and control multiple processes. Processors  332 ,  352 , or  362  may implement virtual machine technologies or other known technologies to provide the ability to execute, control, run, manipulate, store, etc. multiple software processes, applications, programs, etc. In another example, processors  332 ,  352 , or  362  may include a multiple-core processor arrangement configured to provide parallel processing functionalities to allow product recommendation system  330 , query system  350 , or customer affinity system  360  to execute multiple processes simultaneously. One of ordinary skill in the art would understand that other types of processor arrangements could be implemented that provide for the capabilities disclosed herein. 
     Product recommendation system  330 , query system  350 , and customer affinity system  360  may each comprise memory  334 ,  354 , and  364 , respectively. Memories  334 ,  354 , or  364  may store one or more operating systems that perform known operating system functions when executed by processors  332 ,  352 , or  362 . By way of example, the operating system may include Microsoft Windows, Unix, Linux, Android, Mac OS, iOS, or other types of operating systems. Accordingly, examples of the disclosed invention may operate and function with computer systems running any type of operating system. Memories  334 ,  354 , or  364  may be a volatile or non-volatile, magnetic, semiconductor, tape, optical, removable, non-removable, or other type of storage device or tangible computer readable medium. 
     Product recommendation system  330 , query system  350 , and customer affinity system  360  may each comprise databases  336 ,  356 , or  366 . Databases  336 ,  356 , or  366  may include, for example, Oracle™ databases, Sybase™ databases, or other relational databases or non-relational databases, such as Hadoop™ sequence files, HBase™, or Cassandra™. Databases  336 ,  356 , or  366  may include computing components (e.g., database management system, database server, etc.) configured to receive and process requests for data stored in memory devices of the database(s) and to provide data from the database(s). Databases  336 ,  356 , or  366  may include NoSQL databases such as HBase, MongoDB™ or Cassandra™. Alternatively, databases  336 ,  356 , or  366  may include relational databases such as Oracle, MySQL and Microsoft SQL Server. In some embodiments, database  336  may take the form of servers, general purpose computers, mainframe computers, or any combination of these components. 
     Databases  336 ,  356 , or  366  may store data that may be used by processors  332 ,  352 , or  362 , respectively, for performing methods and processes associated with disclosed examples. Databases  336 ,  356 , or  366  may be located in product recommendation system  330 , query system  350 , and customer affinity system  360 , respectively, as shown in  FIG. 3 , or alternatively, it may be in external storage devices located outside of product recommendation system  330 , query system  350 , and customer affinity system  360 . Data stored in database  336  may include product categories, similarity scores, generated lists of products, generated lists of recommended products, thresholds, product price, aggregated customer actions, search trends, historical data. Data stored in database  356  may include queries submitted by users, keywords included in queries, keywords associated with a product identifier, historical data, etc. Data stored in database  366  may include filter applications submitted by users (e.g., product dimensions, product brands, product price minimum, product price maximum, product price range, historical data, etc.) or product specifications, such as product dimensions, product brands, product colors, product storage capacity, associated keywords or products, etc. 
     User device  320  may be a tablet, mobile device, computer, or the like. User device  320  may include a display. The display may include, for example, liquid crystal displays (LCD), light emitting diode screens (LED), organic light emitting diode screens (OLED), a touch screen, and other known display devices. The display may show various information to a user. For example, it may display a user interface element (e.g., on a webpage associated with SRP of  FIG. 1B ), which may include a filter application for a list of products, options for submitting a query, options for selecting a product, options for adding a product to a cart, options for purchasing a product, options to sort a generated list of recommended products by price, similarity score, or sales volume, buttons for the listed examples, etc. 
     User device  320  may include one or more input/output (I/O) devices. The I/O devices may include one or more devices that allow user device  320  to send and receive information from user  320 A or another device. The I/O devices may include various input/output devices, a camera, a microphone, a keyboard, a mouse-type device, a gesture sensor, an action sensor, a physical button, an oratory input, etc. The I/O devices may also include one or more communication modules (not shown) for sending and receiving information from product recommendation system  330 , query system  350 , or customer affinity system  360  by, for example, establishing wired or wireless connectivity between user device  320  and network  310 . 
     In some embodiments, user  320 A may be an internal user (e.g., employees of an organization that owns, operates, or leases systems  100  or  300 ) or an external user (e.g., an online shopper). 
     In some embodiments, system  300  may receive, from user device  320 , a query (e.g., a search request). External front end system  103 , in some embodiments, may be implemented as a computer system that enables external users to interact with one or more systems in system  100 . For example, in embodiments where system  100  enables the presentation of systems to enable users to place an order for an item, external front end system  103  may be implemented as a web server that receives search requests, presents item pages, and solicits payment information. System  300  may extract at least one keyword from the query. System  300  may determine a user identifier (e.g., a customer identification, user identification, computer identification, name, address, e-mail address, phone number, etc.) and a product identifier (e.g., product type keywords associated with at least one product category, a barcode, an image, a text string, an RFID tag, or the like) based on the extracted keywords. The user identifier may be associated with user  320 A (e.g., an online shopper). 
     System  300  may search a database  346  containing search action logs associated with the user identifier and the product identifier. Database  346  may include historical user actions associated with various users (e.g., products users searched, products users purchased, queries users submitted, etc.) or historical data associated with a plurality of product identifier customers may interact with on a webpage (e.g., while browsing a webpage, selecting a product on a webpage, adding a product to a cart on a webpage, purchasing a product on a webpage). Although database  346  is depicted as separate from databases  336 ,  356 , and  366 , in some embodiments, database  346  may be integrated with one or more of databases  336 ,  356 , and  366 . 
     In some embodiments, product recommendation system  330  may use a model to predict at least one recommended product based on the user identifier and the product identifier. For example, product recommendation system  330  may determine a time span associated with the user identifier by calculating a time in which user  320 A may perform a predetermined number of actions. For example, the predetermined number of actions may be determined based on historical data associated with a plurality of product identifier customers may interact with on a webpage (e.g., while browsing a webpage, selecting a product on a webpage, adding a product to a cart on a webpage, purchasing a product on a webpage). For example, the predetermined number of actions may be an average number of actions customers may perform starting from first searching for a product to purchasing a product. In some embodiments, the time span may be associated with an average amount of time in which a customer may browse for and purchase a product. In some embodiments, the actions may include at least one of selecting a product on a webpage, adding a product to a cart on the webpage, or purchasing a product on the webpage. 
     Product recommendation system  330  may retrieve at least one query submitted by a user associated with the user identifier during the time span from query system  350 . In some embodiments, the queries may include at least one keyword associated with a product identifier. In some embodiments, product recommendation system  330  may retrieve at least one filter application submitted by user  320 A during the time span from customer affinity system  360 . The filter applications may include at least one of product dimensions, product brand, product price. In some embodiments, a user interface associated with a webpage may include a filter application, where user  320 A may use the filter application on a list of products on a webpage (e.g., a list of products provided when the user submits a query). In some embodiments, product recommendation system  330  may retrieve at least one product specification associated with at least one product associated with the retrieved queries or filter applications. In some embodiments, the product specifications may include at least one of product dimensions, product brands, product colors, or product storage capacity. 
     In some embodiments, query system  350  may extract attributes from queries submitted by users. For example, query system  350  may extract keywords from queries. In some embodiments, customer affinity system  360  may extract attributes from filter applications applied by users and attributes from product specification. For example, customer affinity system may extract filter applications (e.g., product dimensions, product brands, product price minimum, product price maximum, product price range, etc.) and associated keywords or products. In some embodiments, customer affinity system may extract product specifications associated with keywords or products with which users have interacted (e.g., selecting a product on a webpage, adding a product to a cart on the webpage, purchasing a product on the webpage, etc.). 
     In some embodiments, product recommendation system  330  may extract attributes from historical data over moving windows of time to train and generate a model. In some embodiments, product recommendation system  330  may use the model and the extracted attributes from the queries, the filter applications, and the product specifications to determine a product category associated with the user identifier and the product identifier. In some embodiments, the training data may include at least one of historical queries, historical filter applications, or historical product specifications of a plurality of customers. 
     For example, attributes from historical data of queries may include laptops, Samsung Laptops, 15-inch Samsung Laptops, 15-inch Gaming laptops, etc. In some embodiments, product recommendation system  330  may use the extracted attributes to determine at least one product category (e.g., laptops) associated with the queries. In some embodiments, attributes from historical data of filter applications may include a 15-inch size filter, a ‘Samsung’ brand filter, a less than $300 price filter, etc. Product recommendation system  330  may use the extracted attributes to determine that at least one product category associated with the filter applications includes laptops. In some embodiments, attributes from historical data of product specifications may include a 15-inch size associated with Samsung or Sony laptops customers have selected during a time span (e.g., two weeks). Product recommendation system  330  may use the extracted attributes to determine that at least one product category associated with the product specifications includes high-end laptops. 
     In some embodiments, product recommendation system  330  may generate a list of products based on the determined product category. For example, product recommendation system  330  may generate a list including all products with which user  320 A (associated with the user identifier) engaged (e.g., products the user selected on a webpage, added to a cart on the webpage, or purchased on the webpage). In some embodiments, product recommendation system  330  may retrieve data from at least one of database  346  (the search action logs), query system  350 , or customer affinity system  360  to generate the list. In some embodiments, the list of products may be generated based on user actions performed during the time span. For example, product recommendation system  330  may generate a list of products with which user  320  engaged in the past two weeks. 
     In some embodiments, product recommendation system  330  may calculate a similarity score for each product on the generated list. In some embodiments, product recommendation system  330  may calculate the similarity score based on a comparison of attributes of products on the generated list to the determined product category. In some embodiments, products with more attributes in common with attributes of the determined product category may have a higher similarity score. In some embodiments, product recommendation system  330  may remove products with similarity scores below a threshold from the generated list of products. In some embodiments, similarity scores may be calculated using any combination of methods described below. 
     In some embodiments, the threshold may be determined by an internal user. In some embodiments, product recommendation system  330  may determine the threshold based on historical data for all customers. In some embodiments, when all of the products on the generated list have similarity scores below the threshold, a new threshold may be determined (e.g., a default threshold). In some embodiments, all the products may remain on the generated list. In some embodiments, no recommended products may be provided. For example, product recommendation system  330  may calculate a threshold based on a deviation in historical values (e.g., product price, product categories, aggregated customer actions, etc.). For example, product recommendation system  330  may not calculate similarity scores for products with attributes that deviate more than a predetermined value from historical averages of attributes for those products. In some embodiments, product recommendation system  330  may end the running model when no products have a similarity score that meets the threshold. 
     In some embodiments, product recommendation system  330  may generate a list of recommended products by calculating a similarity score (e.g., a numerical value) for each product on the generated list of products. In some embodiments, product recommendation system  330  may calculate the similarity scores by assigning at least one weighted value to at least one factor. In some embodiments, the at least one factor may include historical user data of at least one of selecting a product on a webpage, adding a product to a cart on the webpage, or purchasing a product on the webpage. For example, each user engagement with a product may be a factor with a value of “1” (e.g., adding a product to a cart on a webpage five times may have a sum of factors of “5”). Product recommendation system  330  may assign a weighted value to a factor by multiplying a weighted value by the value of the factor. For example, selecting a product on a webpage may be assigned a weighted value of “1,” adding a product to a cart on a webpage may be assigned a weighted value of “3,” and purchasing a product on a webpage may be assigned a weighted value of “10” (e.g., so that products that were adding to a cart have higher similarity scores than products that were selected on a webpage). 
     For example, in some embodiments, attributes of products used to calculate similarity scores may include at least one of product price, product category, or aggregated customer actions. For example, product recommendation system  330  may calculate similarity scores based on a comparison of product prices on the generated list of products to the product price of the product identifier associated with the determined product category. In some embodiments, a threshold may include a price minimum, maximum, or range and product recommendation system  330  may remove products with similarity scores that do not meet the threshold from the generated list of products. 
     In some embodiments, product recommendation system  330  may determine search trends (e.g., user is searching for a discounted product, user is searching for specific brand of product, user is searching for a size range of a product, etc.) based on the extracted attributes and assign weighted values to factors in calculating the similarity score based on the search trends. For example, product recommendation system  330  may assign a higher weighted value to product price factors for products that have prices within a determined price range (e.g., the price range may be the average price within a predetermined deviation for products with which the user interacted). For example, each product price may be a factor with a value of “1.” Product recommendation system  330  may assign a weighted value to a factor by multiplying a weighted value by the value of the factor. For example, engagement with a product that has a product price outside a determined price range may be assigned a weighted value of “1” while engagement with a product that a has a product price within a determined price range may be assigned a weighted value of “10.” 
     In some embodiments, product recommendation system  330  may calculate similarity scores based on a comparison of product categories on the generated list to the determined product category. In some embodiments, product recommendation system  330  may remove products with similarity scores that indicate that the products do not belong to the determined product category from the generated list of products. For example, user  320 A may frequently or primarily engage with expensive laptops (e.g., Macbooks, Microsoft Surface, etc.) within a two week time span, but also occasionally engage with significantly less expensive laptops (e.g., searching for laptops that are less than $200). Product recommendation system  330  may determine that the product category is expensive laptops and may calculate similarity scores that indicate that the significantly less expensive laptops do not belong to the determined category. Product recommendation system  330  may remove the significantly less expensive laptops from the generated list of products so that only relevant products are recommended to user  320 A. 
     In some embodiments, product recommendation system  330  may calculate similarity scores based on a comparison of aggregated customer actions. For example, aggregated customer actions may include all customer actions (e.g., selecting a product on a webpage, adding a product to a cart on the webpage, purchasing a product on the webpage, etc.) for products belonging to the determined product category in the same time span or a different time span. In some embodiments, product recommendation system  330  may calculate similarity scores based on customer actions in a time span that ends at the point in time when the product belonging to the determined product category was purchased by a customer (e.g., user  320 A). 
     In some embodiments, product recommendation system  330  may calculate similarity scores by assigning different weights to different customer actions. For example, purchasing a product on a webpage may be assigned a higher weight than adding a product to a cart on a webpage and adding a product to a cart on a webpage may be assigned a higher weight than selecting a product on a webpage. For example, each user engagement with a product may be a factor with a value of “1” (e.g., adding a product to a cart on a webpage five times may have a sum of factors of “5”). Product recommendation system  330  may assign a weighted value to a factor by multiplying a weighted value by the value of the factor. For example, selecting a product on a webpage may be assigned a weighted value of “1,” adding a product to a cart on a webpage may be assigned a weighted value of “3,” and purchasing a product on a webpage may be assigned a weighted value of “10” (e.g., so that products that were adding to a cart have higher similarity scores than products that were selected on a webpage). 
     In some embodiments, products with similarity scores based on aggregated customer actions may not be initially included in the generated list of products. For example, product recommendation system  330  may calculate similarity scores based on a comparison of aggregated customer actions after generating the list of products. In some embodiments, product recommendation system  330  may add a predetermined number of products with the highest similarity scores to the generated list of products. In some embodiments, an internal user may determine the number of products to be added to the generated list. In some embodiments, the number of products to be added to the generated list may be determined based on historical data for all customers. For example, historical data may indicate that the predetermined number of products results in a list of products with the lowest amount of deviation in similarity scores. 
     In some embodiments, product recommendation system  330  may determine a plurality of product identifier based on the extracted keywords and determine that the plurality of product identifier belong to the same product category or related product categories. In some embodiments, product recommendation system  330  may determine a plurality of product categories for one or more product identifier. In some embodiments, product recommendation system  330  may perform steps, as described above, to generate a list of products for each determined product category. 
     In some embodiments, product recommendation system  330  may add greater weight to a product when the product appears on more than one generated list, resulting in a higher similarity score for that product. For example, if three lists are generated and product A appears on two lists while product B appears on three lists, product B is assigned a higher similarity score than product A, thereby advantageously resulting in a more accurate generated list for product recommendations. 
     In some embodiments, user  320 A may interact with a user interface element associated with a webpage (e.g., SRP of  FIG. 1B ) to sort the generated list of recommended products. For example, product recommendation system  330  may modify a user interface element so that user  320 A may sort the generated list of recommended products by price, similarity score, sales volume, etc. In some embodiments, product recommendation system  330  may automatically modify the user interface element to display the generated list of recommended products by price, similarity score, sales volume, etc. 
     Referring to  FIG. 4 , a process  400  for AI-based product recommendation generation is shown. While in some embodiments product recommendation system  330  may perform several of the steps described herein, other implementations are possible. For example, any of the systems and components (e.g., system  100 , query system  350 , customer affinity system  360 , etc.) described and illustrated herein may perform the steps described in this disclosure. In some embodiments, the system components in setting  420  may operate in an offline environment while the steps in setting  430  may be performed in a real-time, online environment. 
     In step  401 , system  300  may receive, from user device  320 , a query (e.g., a search request). System  300  may extract at least one keyword from the query. System  300  may determine a user identifier (e.g., a customer identification, user identification, computer identification, name, address, e-mail address, phone number, etc.) and a product identifier (e.g., product type keywords associated with at least one product category, a barcode, an image, a text string, an RFID tag, or the like) based on the extracted keywords. The user identifier may be associated with user  320 A (e.g., an online shopper). 
     System  300  may search a database  346  containing search action logs associated with the user identifier and the product identifier. In some embodiments, product recommendation system  330  may use a model to predict at least one recommended product based on the user identifier and the product identifier. For example, product recommendation system  330  may determine a time span associated with the user identifier by calculating a time in which user  320 A may perform a predetermined number of actions. For example, the predetermined number of actions may be determined based on historical data associated with a plurality of product identifier customers may interact with on a webpage (e.g., while browsing a webpage, selecting a product on a webpage, adding a product to a cart on a webpage, purchasing a product on a webpage). For example, the predetermined number of actions may be an average number of actions customers may perform starting from first searching for a product to purchasing a product. In some embodiments, the time span may be associated with an average amount of time in which a customer may browse for and purchase a product. In some embodiments, the actions may include at least one of selecting a product on a webpage, adding a product to a cart on the webpage, or purchasing a product on the webpage. 
     In step  403 , product recommendation system  330  may retrieve at least one query submitted by a user associated with the user identifier during the time span from query system  350 . In some embodiments, the queries may include at least one keyword associated with a product identifier. In some embodiments, query system  350  may extract attributes from queries submitted by users. For example, query system  350  may extract keywords from queries. 
     In step  405 , product recommendation system  330  may retrieve at least one filter application submitted by user  320 A during the time span from customer affinity system  360 . The filter applications may include at least one of product dimensions, product brand, product price. In some embodiments, a user interface associated with a webpage may include a filter application, where user  320 A may use the filter application on a list of products on a webpage (e.g., a list of products provided when the user submits a query). In some embodiments, product recommendation system  330  may retrieve at least one product specification associated with at least one product associated with the retrieved queries or filter applications. In some embodiments, the product specifications may include at least one of product dimensions, product brands, product colors, or product storage capacity. In some embodiments, customer affinity system  360  may extract attributes from filter applications applied by users and attributes from product specification. For example, customer affinity system may extract filter applications (e.g., product dimensions, product brands, product price minimum, product price maximum, product price range, etc.) and associated keywords or products. In some embodiments, customer affinity system may extract product specifications associated with keywords or products with which users have interacted (e.g., selecting a product on a webpage, adding a product to a cart on the webpage, purchasing a product on the webpage, etc.). 
     In step  407 , product recommendation system  330  may use the model and the extracted attributes from the queries, the filter applications, and the product specifications to determine a product category associated with the user identifier and the product identifier. In some embodiments, the training data may include at least one of historical queries, historical filter applications, or historical product specifications of a plurality of customers. 
     In some embodiments, product recommendation system  330  may generate a list of products based on the determined product category. For example, product recommendation system  330  may generate a list including all products with which user  320 A (associated with the user identifier) engaged (e.g., products the user selected on a webpage, added to a cart on the webpage, or purchased on the webpage). In some embodiments, product recommendation system  330  may retrieve data from at least one of database  346  (the search action logs), query system  350 , or customer affinity system  360  to generate the list. In some embodiments, the list of products may be generated based on user actions performed during the time span. 
     In some embodiments, product recommendation system  330  may calculate a similarity score for each product on the generated list. In some embodiments, product recommendation system  330  may calculate the similarity score based on a comparison of attributes of products on the generated list to the determined product category. In some embodiments, products with more attributes in common with attributes of the determined product category may have a higher similarity score. In some embodiments, product recommendation system  330  may remove products with similarity scores below a threshold from the generated list of products. 
     In step  409 , product recommendation system  330  may generate a list of recommended products by calculating a similarity score for each product on the generated list of products. In some embodiments, product recommendation system  330  may calculate the similarity scores by assigning at least one weighted value to at least one factor. In some embodiments, the at least one factor may include historical user data of at least one of selecting a product on a webpage, adding a product to a cart on the webpage, or purchasing a product on the webpage. 
     For example, in some embodiments, attributes of products used to calculate similarity scores may include at least one of product price, product category, or aggregated customer actions. For example, product recommendation system  330  may calculate similarity scores based on a comparison of product prices on the generated list of products to the product price of the product identifier associated with the determined product category. In some embodiments, a threshold may include a price minimum, maximum, or range and product recommendation system  330  may remove products with similarity scores that do not meet the threshold from the generated list of products. 
     In some embodiments, product recommendation system  330  may determine search trends (e.g., user is searching for a discounted product, user is searching for specific brand of product, user is searching for a size range of a product, etc.) based on the extracted attributes and assign weighted values to factors in calculating the similarity score based on the search trends. For example, product recommendation system  330  may assign a higher weighted value to product price factors for products that have prices within a determined price range (e.g., the price range may be the average price within a predetermined deviation for products with which the user interacted). 
     In some embodiments, product recommendation system  330  may calculate similarity scores based on a comparison of product categories on the generated list to the determined product category. In some embodiments, product recommendation system  330  may remove products with similarity scores that indicate that the products do not belong to the determined product category from the generated list of products. 
     In some embodiments, product recommendation system  330  may calculate similarity scores based on a comparison of aggregated customer actions. For example, aggregated customer actions may include all customer actions (e.g., selecting a product on a webpage, adding a product to a cart on the webpage, purchasing a product on the webpage, etc.) for products belonging to the determined product category in the same time span or a different time span. In some embodiments, product recommendation system  330  may calculate similarity scores based on customer actions in a time span that ends at the point in time when the product belonging to the determined product category was purchased by a customer (e.g., user  320 A). 
     In some embodiments, product recommendation system  330  may calculate similarity scores by assigning different weights to different customer actions. For example, purchasing a product on a webpage may be assigned a higher weight than adding a product to a cart on a webpage and adding a product to a cart on a webpage may be assigned a higher weight than selecting a product on a webpage. In some embodiments, products with similarity scores based on aggregated customer actions may not be initially included in the generated list of products. For example, product recommendation system  330  may calculate similarity scores based on a comparison of aggregated customer actions after generating the list of products. In some embodiments, product recommendation system  330  may add a predetermined number of products with the highest similarity scores to the generated list of products. In some embodiments, an internal user may determine the number of products to be added to the generated list. In some embodiments, the number of products to be added to the generated list may be determined based on historical data for all customers. For example, historical data may indicate that the predetermined number of products results in a list of products with the lowest amount of deviation in similarity scores. 
     In some embodiments, product recommendation system  330  may determine a plurality of product identifier based on the extracted keywords and determine that the plurality of product identifier belong to the same product category or related product categories. In some embodiments, product recommendation system  330  may determine a plurality of product categories for one or more product identifier. In some embodiments, product recommendation system  330  may perform steps, as described above, to generate a list of products for each determined product category. 
     In some embodiments, product recommendation system  330  may add greater weight to a product when the product appears on more than one generated list, resulting in a higher similarity score for that product. For example, if three lists are generated and product A appears on two lists while product B appears on three lists, product B is assigned a higher similarity score than product A, thereby advantageously resulting in a more accurate generated list for product recommendations. 
     For example, each product may have an initial numerical value for a similarity score based on different factors (e.g., user engagements such as selecting a product on a webpage, adding a product to a cart on a webpage, purchasing a product on a webpage, etc.). Product recommendation system  330  may assign a weighted value to a product by multiplying a weighted value by the initial similarity score of the product. For example, product A may be assigned a weighted value of “2” since it appears on two lists while product B may be assigned a weighted value of “3” since it appears on three lists. 
     In step  411 , user  320 A may interact with a user interface element associated with a webpage (e.g., SRP of  FIG. 1B ) to sort the generated list of recommended products. For example, product recommendation system  330  may modify a user interface element so that user  320 A may sort the generated list of recommended products by price, similarity score, sales volume, etc. In some embodiments, product recommendation system  330  may automatically modify the user interface element to display the generated list of recommended products by price, similarity score, sales volume, etc.
