     TECHNICAL FIELD 
       [0002]    The present disclosure relates generally to inventory management in commerce systems, and more particularly to e-commerce systems for brick-and-mortar stores carrying products. 
       BACKGROUND 
       [0003]    The Internet has become the leading marketplace for purchasing goods and services. Consumers can now purchase almost any product, from groceries to vacations, through the internet. There are numerous websites that a consumer can make a purchase through. As an example, Home Depot® owns a website that allows consumers to purchase goods from its various brick and mortar stores. Retail chains, e.g., Target®, and other brick-and-mortar stores can offer goods available at their stores through their websites as well. 
         [0004]    In order to purchase a certain product, a consumer has to search for dedicated electronic commerce (e-commerce) websites that offer the product for sale or search for the product within an e-commerce website. Some existing solutions may further facilitate online purchases and/or enhance in-store selling via e-commerce websites or search engines. However, such solutions typically do not provide accurate availability of goods in local stores. Because many consumers are more interested in finding the product anywhere than in one particular store or from one particular retail chain, e-commerce product listings that only show availability at particular stores are not always desirable. 
         [0005]    Other disadvantages associated with e-commerce websites relate to the fact that a consumer cannot easily note if a certain product is “physically” available in a local store while searching for a website through which to purchase the product. In order to find such information, a consumer first searches for the product through an e-commerce website and then finds a nearby store (if such store exists) that keeps the desired product. Through this process, the inventory is only verified after the product is presented to the consumer. Besides being a cumbersome process for the consumer, e-commerce websites do not always maintain accurate information with regard to the current inventory of local stores. As a result, a product that is available may be presented as unavailable in a certain store, and vice versa. In most cases, the consumer has to directly connect to the local store (by, e.g., phone or email) in order to verify that the product is physically available. This connection requirement leads to fewer sales and consumer frustration. 
         [0006]    Further, some customers are particularly interested in verifying a quantity of goods in stock in addition to merely whether the goods are in stock at a particular store. For example, a customer painting his or her entire house may wish to verify that he or she will be able to purchase multiple cans of the same paint from the same store. Verifying that a sufficient quantity of a product is in stock may require calling a salesperson at the store and requesting the salesperson to manually check inventory, which may be inconvenient to both the customer and to the salesperson. 
         [0007]    In addition, a consumer searching for goods via e-commerce websites can gain knowledge about the local availability of the goods only through e-commerce websites that are related to the local stores. For example, a consumer shopping for a light bulb at the Home Depot® website can only find if the light bulb is available in a nearby Home Depot® store. However, the consumer does not know if the same light bulb is in a different (and possibly closer) store. 
         [0008]    As local businesses, such as brick-and-mortar stores, often do not maintain e-commerce websites and/or do not invest in the promotion of such websites, consumers cannot easily locate and purchase goods offered by such businesses except by manually requesting information directly from the businesses. Further, even if such brick-and-mortar stores regularly stock particular goods, a consumer cannot find a particular local store that has the good in stock without searching every local store, either in person or by calling the store, for that good until the user finds a store that has the good in stock. This search can be time-consuming, physically demanding, expensive, and may involve the consumer dealing with adverse weather conditions in pursuit of the goods. 
         [0009]    Moreover, from the perspective of the business, the inability of consumers to efficiently determine local availability of goods may prevent those consumers from having a definitive answer regarding whether a particular product is available for purchase and, as such, may lead to reduced sales. Such reduced sales may cause the local stores and/or distributors to stop carrying particular products even when there is sufficient demand for the products to justify carrying them. 
         [0010]    Moreover, brick-and-mortar stores generally stock products without maintaining or otherwise dynamically updating the inventory as products are added or removed from the store. This leads to inaccurate inventory data that prevents local stores and distributors from determining, in real-time, which product is in short supply, out of stock, and so on, except by manually taking inventory (e.g., counting stock, subtracting numbers of goods sold from numbers of goods delivered, and so on). Such information is further valuable to distributors, who may wish to contact and supply inventory to the stores ahead of time (i.e., before the stores run out of stock). 
         [0011]    In addition to the above, merchants and, in particular, brick-and-mortar stores, often do not invest in generating quality and accurate media assets related to the products offered for sale. A media asset may include, for example, a picture, a video clip, a textual description, and the like. As a result, a product is often identified merely by its stock keeping unit (SKU) which may be unique to a particular store, or by its universal product code (UPC). It would be further useful for consumers to be able to visually verify products that they are seeking from local stores. 
         [0012]    It would therefore be advantageous to provide an inventory management system to be integrated in e-commerce solutions that overcomes the deficiencies noted above.

     DETAILED DESCRIPTION 
       [0021]    It is important to note that the embodiments disclosed herein are only examples of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed embodiments. Moreover, some statements may apply to some inventive features but not to others. In general, unless otherwise indicated, singular elements may be in plural and vice versa with no loss of generality. In the drawings, like numerals refer to like parts through several views. 
         [0022]      FIG. 1  shows an exemplary and non-limiting diagram of a network system  100  utilized to describe the various disclosed embodiments. The system  100  includes a network  110 , a plurality of user devices  120 - 1  through  120 - n , a server  130 , an inventory management system  140 , a plurality of vendor devices  150 - 1  thorough  150 - n  (hereinafter referred to individually as a vendor device  150  and collectively as vendor devices  150 , merely for simplicity purposes), a seed database  160 , and a media assets database  170 . 
         [0023]    The network  110  may be the Internet, the world-wide-web (WWW), a local area network (LAN), a wide area network (WAN), a metro area network (MAN), and other networks configured to communicate between the elements of the  110 . A user device  120  may be a personal computer (PC), a personal digital assistant (PDA), a mobile phone, a smart phone, a tablet computer, a wearable computer device, an e-reader, a game console, and the like. 
         [0024]    The vendor devices  150  are operated by vendors and may be any type of an e-commerce system, a connected point of sale (POS), or an inventory management system operated by the vendor. A vendor may be a brick-and-mortar vendor, an online vendor, and the like. Examples for brick-and-mortar vendors include, but are not limited to, local stores, restaurants, bars, hotels, service providers, and other sellers of goods. In certain embodiments, the vendor devices  150  are operated by manufacturers, distributors, importers, and/or wholesalers of the products. For example, a vendor device may be operated by a winery or by a liquor distributor. 
         [0025]    The server  130  and the inventory management system  140  are also communicatively connected to the network  110 . The server  130  may be configured to analyze any media content displayed over a user device  120  to determine if there are any goods that are related to, or mentioned in, the content viewed by a user of the user device  120 . Such content may be, but is not limited to, a webpage, an e-book, an electronic game, and the like. The media content may be pre-processed and sent to the server  130  by a script, a widget, or any other virtual point of sale  125  executed over the user device  120 . Additionally, the location of the displayed content such as, e.g., a URL of a webpage, may be sent to the server  130 . Moreover, the content may be analyzed by the widget  125  to determine if such content includes at least one product that is related to, or mentioned in, the content viewed by a user of the device  120 . The widget  125  may be, but is not limited to, embedded in a webpage, an agent installed in the user device, a web browser add-on, an application, integrated in a Document Object Model (DOM), and the like. 
         [0026]    The server  130  and/or the widget  125  may perform textual analysis, image analysis, and or/video analysis to determine if there is at least one product that is related to, or mentioned in, the content viewed by a user of the user device  120 . The determination may be performed against a configurable set of product names and a configurable list of vendors that offer these products for sale. For example, if the server  130  and/or the widget  125  is configured with the product names “New Balance  930 ” and “Nike Air Jordan”, appearances or mentions of these products will be identified via the textual, image, and/or video analysis. 
         [0027]    The server  130  may also be configured with a list of vendors that offer products designated in sets of product names. It should be noted that any entity such as a vendor, merchant, seller, and/or service provider can register to offer its products for sale. The registration may be with, but not limited to, the server  130 , the inventory management system  140 , and so on. To this end, each such entity is merely required to provide information such as, but not limited to, a list of products and their prices, a location of a store of the entity, operation hours, accepted payment methods, current inventory levels, and so on. It should be further noted that some of the details required for the registration can be retrieved directly from the vendor devices  150  by the server  130 . In an embodiment, the inventory management system  140  may be configured to estimate inventory levels as described further herein below for stores of registered entities. 
         [0028]    In response to determination of at least one product by the server  130  or the widget  125 , a location, a purchase history, and/or a user profile of a user of the user device  120  is typically determined. This information can be retrieved through a GPS, through a web browser installed in the user device  120 , based on a network connection, and/or provided by the user. 
         [0029]    According to various exemplary embodiments, based on this information, the server  130  may be configured to identify one or more of the vendors. For example, the server  130  may be configured to identify vendors that are in the vicinity of the user device  120  and/or that the user has previously purchased from. The vicinity may include, but is not limited to, in the same neighborhood, borough, town, city, state, or country as the user device; within a predetermined distance of the user device; within a predetermined travel time from the user device based on mode of locomotion (e.g., less than 5 minutes by car); and so on. 
         [0030]    Thereafter, the server  130  is configured to query the inventory management system  140  about the inventory level of each identified product offered for sale by vendors in the proximity of the user (consumer). An exemplary and non-limiting inventory management system  140  is described further herein below with respect to  FIG. 2 . 
         [0031]    In an embodiment, the inventory management system  140  is configured to provide information regarding inventories of products offered by stores. The information may be displayed via, e.g., a virtual POS displayed on a user device. Such information may include, but is not limited to, current inventories of products in stock, the stores having the products in stock, media assets of the products in stock, and so on. To this end, in an embodiment, the inventory management system  140  is configured to monitor and estimate the inventory levels of products (goods) being sold by vendors. The inventory management system  140  may or may not be connected to the vendor devices  150 . As a result, the inventory levels periodically estimated by the inventory management system  140  are not dependent on updates to inventory data entered or provided by vendors via the vendor devices  150 . For example, such estimation may be performed weekly, daily, monthly, and so on. 
         [0032]    In an embodiment, the inventory management system  140  is configured to estimate the current inventory level of a product at a certain vendor at a given point in time. Alternatively or additionally, the inventory management system  140  is configured to determine the probability that a particular vendor has a particular quantity of the product in stock at a given point in time. As will be discussed in more detail below, the inventory level is estimated based on seed inventory data. The seed inventory data represents a baseline inventory level at a given time. The seed inventory level may be determined based on seed inventory heuristics such as, but not limited to, distributions of inventory received from a distributor of the product; full or partial information regarding the product received from the vendor, an importer of the product, and/or a wholesaler; user reports; and/or other data extracted from other sources available over the web or contributed by users. It should be noted that the seed inventory level does not need to be directly provided by a vendor (i.e., the vendor does not need to explicitly send a seed inventory level value). Rather, the seed inventory may be determined implicitly and/or based on information maintained by entities other than the vendor (e.g., a distributor may note quantities of products sold to particular vendors). Accordingly, the inventory management system  140  may estimate a current inventory without requiring that a vendor maintain and update the seed inventory. 
         [0033]    In an embodiment, the seed information can be determined implicitly based on the inventory distributed to all stores in a limited geographic area. As a non-limiting example, if a wholesaler reports selling 1,000 bottles of a particular wine in a city and there are 100 comparable stores that sell the wine in that city, it may be estimated that each store has an initial inventory of 10 bottles of the wine. In a further embodiment, the seed information may be further determined based on, e.g., relative sizes of the comparable stores, known relations between stores, known inventory levels of other products in a given store, and historical inventory levels (such as, e.g., previously determined seed inventory levels and/or estimated inventory levels). Size may be based on, but is not limited to, a number of employees working for the store, an area or volume of the physical store, an annual gross income, previous quantity of sales of the product and/or associated products, and so on. As a non-limiting example, only two stores in a city sell a particular brand of cheese. The larger store occupies twice the square area of the smaller store. If a wholesaler reports selling 300 packages of the cheese in the city, the initial inventory of the larger store may be determined to be 200 packages i.e., twice the initial inventory of the smaller store. 
         [0034]    In an embodiment, the seed inventory information is saved in the seed database  160 . The inventory management system  140  may be communicatively connected to the seed database  160 . In another embodiment, the seed database  160  is embedded in the inventory management system  140 . The inventory management system  140  may be further configured to update the initial seed inventory level based on a plurality of the seed inventory heuristics, and preferably based on purchases made through the server  130 . Updates to the estimated inventory may further be based on information received from the vendors. It should be noted that not all purchases are performed through the server  130 . As a result, information received from the server  130  respective of purchases may include an incomplete record of purchases. 
         [0035]    According to some exemplary embodiments, the heuristics used in estimating current inventory levels of products may include, but are not limited to, a type of product, a time of day, weekly or annual trends, seasonal trends, industry patterns, patterns of sales in comparable stores, trends for associated products, promotions, external events, location of a vendor&#39;s store, combinations thereof, and so on. Two stores may be comparable if, e.g., the two stores carry the same type of products, the two stores are proximate to each other (i.e., within a predetermined geographical distance of each other), combinations thereof, and so on. The type of product may influence inventory determinations because sales of particular products tend to fluctuate based on, e.g., the passage of time, industry trends, and so on. 
         [0036]    As a non-limiting example of a time of day heuristic, the stock of a product may tend to go down later in the day (e.g., the stock of a product at 5 P.M. will likely be lower than the stock at 9 A.M., assuming no shipments are made during the day). Weekly trends may include particular days of the week in which certain products are sold in higher volume. As a non-limiting example, sales of movie tickets may tend to increase (thereby reducing stocks of such tickets) over the weekend (e.g., Friday, Saturday, and Sunday). 
         [0037]    Annual trends may include holidays (e.g., Fourth of July, Halloween, Thanksgiving, etc.). Sales of goods may be higher during certain times surrounding or leading up to holidays. As a non-limiting example, stores selling costumes may have reduced costume inventories in the month preceding October 31 st  due to the approach of Halloween. 
         [0038]    Seasonal trends may be related to holiday trends and/or influenced by broader repercussions of shifts in weather. As non-limiting examples, sales of red wine may increase during winter, sales of beers and white wines may increase during the summer, and so on. Industry trends may include shifts in sales that occur due to, for example, increased general popularity of certain products. As a non-limiting example, a product shown on a news show may begin seeing increased sales thereafter. As another example, sales of all products featuring a particular vegetable may increase when the vegetable is reported as being a “superfood.” In an exemplary embodiment, seasonal and/or industry trends may be fed to the inventory management system  140  by external servers or services and/or may be input by a user. 
         [0039]    In another embodiment, the inventory management system  140  may be configured to detect and analyze trends and patterns via a machine learning process, thereby adapting estimations accordingly. In a further embodiment, such detection may be based on purchase transactions received from, e.g., the server  130 . As a non-limiting example, increases in numbers of purchase transactions of pumpkin spice received during September and October may be detected as a seasonal trend. Accordingly, expected sales of pumpkin spice may be higher during the months of September and October. 
         [0040]    In an embodiment, the inventory management system  140  may be configured to determine increased orders and/or decreased inventory of nearby stores that sell a product when estimated inventories for comparable stores are low. As a non-limiting example, if a nearby vendor who documents its inventory of a particular product (e.g., a nearby Wal-Mart® that makes its inventory available online) indicates that it is nearly sold out of a particular product, the inventory of that product held by nearby brick-and-mortar stores may be estimated to be lower than normal. 
         [0041]    The heuristics may further include sales of associated products. Associated products include products that are typically sold together. An associated product may be, but is not limited to, an accessory or an otherwise complimentary product. As non-limiting examples, an associated product for wine may be cheese, an associated product for boots may be a purse, an associated product for a meal order may be a beverage, an associated product for a computer game may be downloadable content for that game, and so on. 
         [0042]    Associated product pairings may further be determined based on, e.g., seasonal trends, annual trends, and so on. As a non-limiting example, candy and costumes may be considered associated products during October due to Halloween, while candy and costumes are not considered associated products during the remainder of the year. 
         [0043]    The heuristics may further include current promotions associated with each identified product. As an example, a happy hour, a valid coupon, and the like can be determined to be current promotions. Such promotions may be input to the inventory management system  140  by the server  130 , by the vendors, and/or distributors of the product. The estimated inventory level of a product that is the subject of an ongoing promotion may be determined to be lower than that of the product without promotions. 
         [0044]    The heuristics may further include the location of a vendor&#39;s store. Stores in higher traffic and/or more densely populated areas (e.g., a city as opposed to a rural area) will often tend to see higher average sales than stores in less active shopping areas. In an embodiment, the effect of location on sales may further be based on one or more trends in sales in the particular location. As an example, sales of football paraphernalia for the New York Giants® football team in New Jersey may be increased when trends in sales indicate that sales of such paraphernalia in states near New York increases. 
         [0045]    The heuristics may further include external events. External events are occurrences in the area that would likely cause a temporary increase in sales of particular products. As a non-limiting example, the existence of a wine festival nearby may result in increased wine sales, a book signing by a famous author may lead to increased sales of that author&#39;s works, the premiere of a movie may lead to increased sales of merchandise associated with the movie, and so on. 
         [0046]    The server  130  may be configured to send a list of products and/or vendors to the inventory management system  140 . In response, the inventory management system  140  is configured to return the probability that each vendor keeps a sufficient inventory level of a product. A sufficient inventory level is a configurable parameter such as, e.g., an integer number equal to or greater than 1. As an example, for one order of a product P 1  and vendors V 1 , V 2  and V 3 , the system  140  estimates and returns the values 0.4, 0.9 and 0. That is, the probabilities that vendors V 1 , V 2 , and V 3  currently hold product P 1  in their inventory are 0.4, 0.9, and 0, respectively. Based on the returned probabilities, the server  130  is configured to determine whether there is a sufficient inventory of product. 
         [0047]    At least upon determination that there is a sufficient inventory level for at least one identified product, the server  130  is configured to cause the widget  125  to modify the content (e.g., a webpage) displayed over the user device  120  to inform the user the content is available for sale. As a non-limiting example, a call-to-action (CTA) button in a form of an icon or any other interactive feature can be added to a webpage indicating that a product(s) mentioned in the webpage is available for sale by vendors. It should be noted that the CTA button may be in any size, shape, and/or color. In an embodiment, the appearance of the CTA button may be determined based on the probability that a respective product is available. 
         [0048]    Upon detection of a user&#39;s gesture with respect to the CTA button, a virtual point of sale is generated as an overlay over the displayed content (e.g., on a user device). The virtual point of sale allows the consumer to purchase the product directly from the vendor without navigating to a different web site. That is, the generated virtual point of sale operates completely within the webpage or other content (e.g., e-book) currently displayed over the user device  120 . 
         [0049]    In an embodiment, the server  130  is configured to generate the virtual point of sale by means of the widget  125 . To this end, the server  130  is configured to select vendors determined to have inventory of the identified product. The selection is based on estimated current inventory levels generated by the inventory management system  140 , the probabilities computed by the inventory management system  140 , promotion information, a location of a vendor with respect to the user, or any combination thereof. The server  130  is further configured to query a vendor through a respective vendor device  150  about the price of the product and applying a current promotion(s). Thus, a list of vendors and the product prices are displayed to the user as part of the virtual point of sale. In an embodiment, a media asset associated with the product is also displayed to the user. The media assets may be obtained from the media assets database  170 . 
         [0050]    The server  130  may be configured to enable a purchase transaction of the user for the product on behalf of the vendor, to notify the vendor about the purchase, and/or to inform the user when the product will be ready for pick-up or delivery from the vendor. In an embodiment, directions to the vendor may be displayed to the user. The purchase transaction may also allow the user to RSVP, chat, or speak with a vendor&#39;s sales representative, share the product with others (e.g., social connections), and so on. Thus, the user of a user device  120  can perform and complete the entire purchase transaction from the virtual point of sale without navigating away from the current webpage. In an embodiment, to allow the completion of the purchase transaction, a direct communication channel can be established between a vendor device  150  of the respective vendor and a user device  120 . Such a communication channel may be realized through Network Protocols, Interactive Protocols, emails, SMS messages, instant messaging, or any other generic or dedicated communication protocol. 
         [0051]    In an embodiment, the inventory management system  140  is configured to receive information from the server  130  upon completion of a purchase transaction. Such information includes the product and the respective vendor through which a purchase has been made. The inventory management system  140  is configured to update the inventory level of the respective product and vendor based on any such purchase transaction information. 
         [0052]    The media assets database  170  contains media assets that can be associated with the products maintained by the inventory management system  140 . A media asset may include, but is not limited to, a picture, a video clip, a textual description, or any other media identifying or otherwise describing a product. For example, a media asset of a wine bottle may be a picture of the wine&#39;s label. As another example, media assets of a vacuum cleaner may include a picture of the vacuum cleaner, a video clip demonstrating the vacuum in use, a textual description of the vacuum&#39;s features, and a textual description of the vacuum cleaner&#39;s technical specifications. 
         [0053]    Each media asset stored in the media assets database  170  may be associated with a unique identifier such as an SKU. In an embodiment, the virtual point of sale generated by the server  130  may include the media assets associated with the SKU of each product identified in a webpage. To this end, the inventory management system  140  may further be configured to provide media assets associated with each identified product to the server  130  for display via, e.g., the virtual point of sale. 
         [0054]    In an embodiment, the inventory management system  140  is communicatively connected to the media assets database  170 . In another embodiment, the media assets database  170  is embedded in the system  140 . Communications between the inventory management system  140  and the media assets database  170  allows various vendors to share access to public assets associated with products while only allowing each vendor to access its own private assets (e.g., prices, inventory levels, and so on). Such public assets may include, but are not limited to, images and videos of products, product descriptions, products reviews, and so on. As a result, information displayed to a user may include public assets identifying the product as well as private assets relating to purchasing the product. 
         [0055]    According to various embodiments, the vendor devices  150  interface with the inventory management system  140 . This interface allows each vendor to manage (i.e., view, provide information about, etc.) its inventory via the inventory management system  140 . It should be noted that inventory data of each vendor is typically stored separately from that of other vendors, such that, for example, a vendor accessing the inventory management system  140  through the vendor device  150 - 1  may not be able to view any information of a vendor accessing the system  140  through the vendor device  150 -N. 
         [0056]    In certain embodiments, the inventory management system  140  is configured to analyze information received from a vendor respective of inventory data maintained by the inventory management system  140 . This analysis is utilized, in part, to verify information provided through the vendor devices  150  (e.g., as part of the seed data), to generate inventory analytics, and so on. Thus, the inventory management system  140  may be configured to determine whether inventory provided by a vendor via the vendor device  150  is accurate. This determination is achieved by cross-correlating information entered by the vendor with information stored in the inventory management system  140  (or information provided by external channels). 
         [0057]    Such cross-correlation may include comparing values provided by a vendor to known values of, e.g., that vendor, other comparable vendors, combinations thereof, and so on. For example, if a vendor enters a product P 1  with a quantity Q 1  and a tag price TP 1 , these details can be checked against information related to the same product that was provided by other vendors. If the tag price TP 1  is lower or higher than a price tag TP X  by a predefined threshold, the inventory management system  140  is configured to generate a warning message. In another embodiment, the inventory management system  140  is configured to generate an error message if the quantity Q 1  is lower or higher than the quantity reported to be typically shipped to the vendor. 
         [0058]    In an embodiment, inventory information may be analyzed to generate one or more inventory analytics. The generation of inventory analytics may be for a specific product or group of products, a specific vendor or group of vendors, or any combination thereof, and may indicate trends, patterns, and so on. For example, a rapid decline in the inventory level of a certain product may indicate that the product is trendy (i.e., there has been an increasing trend in sales of the product). In such a case, a message may be generated and sent to vendors to suggest that those vendors increase their inventories of the trendy product. Further, the inventory analytics may be utilized to identify trends in inventories. Such trends may be further used when estimating inventory levels. In particular, inventory analytics for a particular product may be utilized to determine whether to raise or lower the estimate of the product for any particular store and/or for all stores. 
         [0059]    As another non-limiting example, a rapid decline in the inventory level of a certain product with a tag price of TPy and static inventory level of the same product priced at tag price TPz may indicate that the right price for the product is between TPy and TPz. In a further embodiment, the inventory analytics may be generated in response to a request from, e.g., a consumer, a vendor, a distributor, and so on. 
         [0060]    It should be noted that the above description discusses the inventory management system estimating inventories and probabilities respective of a request from the server  130  attempting to generate a virtual point of sale including product information merely for simplicity purposes and without limitation on the disclosed embodiments. In various embodiments, the inventory management system  140  may provide information directly to a consumer, vendor, distributor, and so on. Such information may be provided pushed by the system  140  or pulled by the other devices. 
         [0061]    The information may include, but is not limited to, estimated inventory levels of products, probabilities that the store has certain quantities of products in stock, trends or patterns in sales, and so on. In a further embodiment, each vendor may configure the inventory management system  140  with one or more permissions regarding provision of information. As a non-limiting example, a vendor may choose to allow the inventory management system  140  to send certain distributors estimated inventory levels for its products. As another non-limiting example, a vendor may choose to allow the inventory management system  140  to send distributors estimated inventory levels but not trends or patterns in sales. 
         [0062]    It should be noted that a widget  125  is described herein merely for simplicity purposes and without limitation on the disclosed embodiments. Other types of virtual points of sale allowing display and/or receipt of information may be utilized without departing from the scope of the disclosure. Additionally, a call to action (CTA) button is described merely for simplicity purposes and without limitation on the disclosed embodiments. Other interactive features using a variety of appearances and/or interactions (e.g., sound, user gestures other than clicking, and so on) may be used in addition to a clickable CTA button without departing from the scope of the disclosure. 
         [0063]    In an embodiment, the inventory management system  140  is integrated in the server  130 . Each of the server  130  and the inventory management system  140  includes at least a memory and processing system (not shown in  FIG. 1 ). The processing system may comprise or be a component of a larger processing system implemented with one or more processors. The one or more processors may be implemented with any combination of general-purpose microprocessors, microcontrollers, graphics processing units (CPUs), digital signal processors (DSPs), field programmable gate array (FPGAs), programmable logic devices (PLDs), controllers, state machines, gated logic, discrete hardware components, dedicated hardware finite state machines, quantum computers or any other suitable entities that can perform calculations or other manipulations of information. 
         [0064]      FIG. 2  is an exemplary and non-limiting schematic block diagram of an inventory management system  140  according to an embodiment. The inventory management system  140  includes a processing system  210 , a memory  220 , a database  230 , a statistical modeler  240 , and an interface  250 . The memory  220  typically contains instructions that, when executed by the processing system  210 , configures the inventory management system  140  to perform the methods described further herein. In particular, the instructions contained in the memory may configure the system  140  to perform the method of estimating a current inventory described further herein below with respect to  FIG. 3 . The processing system  210  may be realized using any of the implementations described in detail herein above. 
         [0065]    The database  230  may be used to store information related to calculating the current inventory of a product in a particular store. Such information may include, but is not limited to, information related to the seed inventory information retrieved from a seed database (as described further herein above with respect to  FIG. 1 ), an initial inventory, a previously determined inventory, a set of heuristics, a set of seed heuristics, and so on. 
         [0066]    The statistical modeler  240  is configured to use information stored in the database  230  to calculate an estimated current inventory of a product in a vendor&#39;s store. In an embodiment, the estimated current inventory may be calculated by applying a Markov model respective of information related to the set of heuristics. As a non-limiting example, a potential customer views a particular toy on a website in December. In this example, the statistical module  240  may apply a Markov model when information in the inventory management database  230  indicates that an initial inventory of the toy in a nearby toy store was likely 20 toys based on a shipment to the toy store 3 days prior. Heuristics considered pursuant to the Markov model illustrate that, although during a “normal” time of year, it would be expected that 2 of the toys in inventory would be sold per day, the holiday shopping season in December leads to increased average sales of 5 toys per day. As a result, it is determined that there is an estimated current inventory of 5 toys left in the store (i.e., an initial inventory of 20 toys minus the product of 5 toys per day by 3 days). The statistical modeler  240  can be implemented as a processing system includes one or more processors as discussed above. 
         [0067]    The interface  250  allows various entities to upload/import and/or retrieve/export data to and from the inventory management system  140 . The various entities include systems or servers, a point of sale (PoS) system or other computing devices of the distributors, importers, regulators, wholesales, vendors, e-commerce systems, and users of such entities. The importing and exporting data may include, but is not limited to, defining external events (e.g., indicating that a wine festival is occurring on a particular week), providing a trend, subscribing to trends detected by the inventory management system  140  (i.e., requesting information regarding trends as they are detected), sending estimated current inventories, sending probabilities, receiving and sending media assets, and so on. 
         [0068]    It should be noted that the connections among components of the inventory management system  140  as illustrated in  FIG. 2  are merely exemplary and do not limit any of the disclosed embodiments. Any or all of the components of the inventory management system  140  may be communicatively or otherwise connected to any other components of the inventory management system  140  without departing from the scope of the disclosure. 
         [0069]      FIG. 3  is an exemplary and non-limiting flowchart illustrating a method for estimating a current inventory level of a particular product at a particular store according to an embodiment. In an embodiment, the method may be performed by an inventory management system (e.g., the inventory management system  140 ). 
         [0070]    In S 310 , the seed inventory level of a product in a store is determined. The seed inventory level may be determined explicitly (e.g., by retrieving the initial inventory value directly from a database) or implicitly (e.g., by retrieving information related to the initial inventory from a database and estimating the initial inventory respective thereof). Information related to the initial inventory may be stored in a local database (e.g., the database  230 ) or may be stored in a remote database (e.g., the seed database  160 ). Determination of seed (initial) inventory levels is described further herein above with respect to  FIG. 1 . The seed inventory level is a baseline value of the inventory level for the product in a store. For example, the seed inventory level may be the inventory value for a store immediately after receiving a shipment of goods. 
         [0071]    In S 320 , respective of the determined seed inventory level, an estimated current inventory level of the product is generated. In an embodiment, the estimated current inventory level is generated based on time elapsed since the seed inventory information is fed to the system. In another embodiment, the estimated current inventory level of the product in the store may be generated based on, but not limited to, an estimated average quantity of the product sold per time period (e.g., hour, day, week, and so on). 
         [0072]    In one embodiment, the average quantity of the product sold per time period is determined respective of one or more heuristics. Such heuristics may include, but are not limited to, a type of product, a time of day, weekly or annual trends, seasonal trends, industry patterns, patterns of sales in comparable stores, trends for complimentary products, promotions, external events, relative size of a vendor&#39;s store, combinations thereof, and so on. Heuristics are described further herein above with respect to  FIG. 1 . 
         [0073]    In S 330 , based on the estimated current inventory of the product in the store, a probability that the store has a certain quantity of the product in stock is determined. In an embodiment, the probability that the store has a particular quantity of the product in stock may be calculated via a Markov model that accounts for the current estimated inventory level. 
         [0074]    In various embodiments, S 330  involves calculating a plurality of probabilities that the store has various quantities of a product in stock. As a non-limiting example, S 330  may yield probabilities {p 1 , p 2 , . . . , p 1 }, where p 1  is the probability that the store has one of the product in stock, p 2  is the probability that the store has two of the product in stock, and so on. In S 340 , the estimated inventory level of the product in the store as well as the computed probabilities are saved in a database (e.g., the database  230 ). 
         [0075]    Optionally, in S 350 , it is determined whether the estimated inventory level is below a predefined threshold and, if so, execution continues with S 360 ; otherwise, execution terminates. In S 360 , an alert indicating a low inventory level is generated and sent (through, e.g., the interface  250 ). The alert may be sent to a vendor, a distributor, and so on. 
         [0076]    As a non-limiting example, based on distributions of 100 tennis rackets in a city having 5 stores that sell tennis rackets, a seed inventory level for a tennis racket of a store in the city is determined to be 20 rackets. The seed inventory level is determined to be based on distributions made two days ago. It is determined that an average sale of tennis rackets per day in such a store is 8. Accordingly, an estimated current inventory of 4 rackets (20 baseline−8 rackets/day times 2 days) is generated. A Markov model is used to determine that a probability of the store having the racket in stock is 80%. Further, based on a suggested threshold of 10 rackets, it is determined that inventory is low, and an alert respective thereof is generated. 
         [0077]    It should be noted that the method can be executed at predefined time intervals (e.g., every 120 hours), when the seed inventory information has been changed, and/or upon a specific external request. For example, the method may be executed upon receiving a request for product information for a virtual point of sale, upon receiving information regarding an external event, and so on. 
         [0078]    According to various embodiments, the inventory data maintained by the inventory management system  140  can be analyzed. The analysis is utilized, in part, to verify information provided through the vendor devices  150  (e.g., as part of the seed data), to generate inventory analytics, and the like. Exemplary and non-limiting embodiments for verification of the inventory data are provided above with respect to  FIG. 1 . 
         [0079]    It should be noted that the method of  FIG. 3  is described herein with reference to a particular store and product merely for the sake of simplicity and without limitation on the disclosed embodiments. The method may be applicable to multiple products and/or stores without departing from the scope of the disclosure. 
         [0080]      FIG. 4  is an exemplary and non-limiting flowchart  400  illustrating a method for identifying a store that is likely to have sufficient quantity of a particular product in stock according to an embodiment. In an embodiment, the identification may be performed by an inventory management system (e.g., the inventory management system  140 ). 
         [0081]    In S 410 , a request to identify a store that is likely to have particular quantity of a product in stock is received. The request may include, but is not limited to, a geographic location of a potential customer, a product description, and a requested quantity. 
         [0082]    In S 420 , based on the geographic location of the potential customer and the product description, it is determined which nearby stores would likely carry the product (even if the product would not necessarily be in stock). A store may be nearby if, for example, the store is within the vicinity of a user device of the potential customer. The vicinity may include, but is not limited to, in the same neighborhood, borough, town, city, state, or country as the user device; within a predetermined distance of the user device; within a predetermined travel time from the user device based on mode of locomotion (e.g., less than 5 minutes by car); and so on. As a non-limiting example, a store may be nearby if it is less than 1 mile away from the potential customer. A store may be likely to carry the product if, for example, the product category aligns with a category of the store, if the store lists the product on its website, and so on. As a non-limiting example of a product category that aligns with a category of a store, a hammer may fall into the product category “home improvement tools” that is typically carried by stores that are categorized as hardware stores. Determination of which stores likely carry the product may reduce utilization of computing resources by pre-filtering stores before generating estimated inventories for each store. 
         [0083]    In S 430 , a probability that each determined store has at least the requested quantity of the product in stock is determined. In an embodiment, the probability that each determined store has at least the requested quantity of product in stock may be the sum of probabilities of the store having quantities of the product that are greater than or equal to the requested probability. For example, if a user requests  3  of a product, the probability that a store has at least 3 of the product in stock may be the sum of the respective probabilities that the store has 3, 4, 5, and so on of the product in stock. Determination of probabilities that stores have particular quantities of products in stock is described further herein above with respect to  FIG. 3 . 
         [0084]    In S 440 , all stores that likely have a sufficient amount of the product in stock are determined. In an embodiment, a store likely has a sufficient amount of the product in stock if, e.g., the probability that the store has the requested quantity of the product in stock exceeds a threshold (e.g., 50%). Such a threshold may vary based on one or more sufficiency heuristics. As a non-limiting example, the threshold may be raised during a season in which more of the product will sell because the inventory of the product at any particular time during a high sales volume season tends to be lower than that of the product at the same time during a normal sales volume season. In another example, the threshold may be set respective of the method of delivery. For example, a higher threshold is set for in-store pick-up than for product shipping because product shipping may allow time for additional deliveries to come in and/or may require an employee to set aside the ordered good. 
         [0085]    In an embodiment, the threshold may further provide an allowance for error. The allowance reduces the chance that an incorrect estimation of inventory will result in improper determination of a store as likely to have the requested quantity of product in stock. Accordingly, the threshold may be further raised depending on the likelihood of sudden significant changes in inventory. As a non-limiting example, the allowance for determination of whether a store has a particular grill in stock may be higher during the month of June than during the month of October because seasonal trends indicate high volumes of grill sales during the summer months. 
         [0086]    In S 450 , each store that likely has a sufficient quantity of the product in stock is returned. In an exemplary embodiment, one store is selected and returned. The selection may be based on, but not limited to, the probability and/or location of each store that likely has a sufficient quantity of the product in stock. For example, if three nearby stores each have a 90% probability of having the product in stock, the store that is closed to the consumer may be selected and returned. In another embodiment, multiple stores may be returned. In a further embodiment, the returned stores may be displayed in a ranking order based on their relative probabilities and/or locations. For example, if three nearby stores have probabilities of 70%, 60%, and 50%, respectively, the three stores may be returned in order from highest to lowest probability. 
         [0087]    In an embodiment, the selection may be further based on one or more user preferences of the consumer requesting a particular quantity of the goods. The user preferences may define an importance of one or more factors such as, but not limited to, probabilities and/or locations of stores having the product in stock. In a further embodiment, the user preferences may rank, weigh, or otherwise prioritize factors based on importance to the user. As an example, the user preferences may rank probability higher than location such that nearby stores having the highest probability of having the requested quantity of product in stock are prioritized over closer stores having lower probabilities. 
         [0088]    As a non-limiting example, a request to identify a nearby store that has at least one pair of a particular shoe in stock, a geographic location of a potential customer, and a product identification number for the shoes are received. The threshold for a store being nearby is within 6 miles of the potential customer. In this example, stores A, B, and C are located 3 miles, 1 mile, and 5 miles away from the potential customer, respectively. Additionally, all three stores are determined to have previously purchased the pair of shoes from a shoe distributor. Thus, stores A, B, and C are determined to be nearby stores that are likely to carry at least one pair of the shoes. 
         [0089]    An initial inventory for store A is determined to be 10 pairs of the shoe. Based on the date and any relevant trends, a current inventory for store A is determined to be 2 pairs of the shoe in stock. Additionally, the probability that store A has one of the pair of shoes in stock is determined to be 0.5. Respective analyses for stores B and C yield initial inventories of 15 pairs of shoes for store B and 13 shoes for store C, current inventories of 3 pairs of shoes for store B and 5 pairs of shoes for store C, and probabilities of 0.8 for store B and 0.8 for store C. A threshold for being likely to have the shoe in stock is determined to be 0.6. In this example, since store B has the highest probability of having at least one pair of the shoe in stock while being the closest store to the potential customer and since the probability for store B is above the threshold probability, store B is selected to be identified.
