20200234324
Online shopping has brought a wide range of societal benefits, such as wider selections, lower prices, and the comfort of shopping from home and having items delivered at the click of a mouse. As online shopping becomes more popular, these benefits accumulate, not only in terms of higher efficiency, but also in terms of improved customer experience.
Challenges remain, however, for both consumers and merchants. Online shopping differentiates itself from shopping in stores by focusing on better prices and a lower hassle shopping experience. There is a concern that customers may be confused by hard to navigate websites, and when a customer attempts to use a website and is rejected, the fear that this customer may be lost, possibly for an extended period of time, becomes especially acute.
Online shopping remains a vibrant and competitive part of the economy, in part because it is so easy for shoppers to move between competing websites. Therefore, there remains a strong need to deliver better prices and a less frustrating experience for customers.
Embodiments of the invention include a computer-implemented method, a system and a computer program product for processing a third-party online coupon. According to one embodiment, a third-party online coupon is received. Text is parsed to determine a merchant's website. The third-party online coupon is parsed to determine a product term. The product term is searched for. The third-party online coupon is tested with a product associated with the product term. The validity of the third-party online coupon with the product is determined.
According to another embodiment, a system for processing online coupons, comprises a database, stored on a non-transitory computer readable medium, of third-party online coupons. There is a database, stored on a non-transitory computer readable medium, of third-party online coupon validation results. There is a database, stored on a non-transitory computer readable medium, of graphs of merchant websites. There is a coupon validator, coupled to the database of third party online coupons, the database of online coupon validation results and the database of graphs, configured to validate third party online coupons with products associated with a product term in a respective third party online coupon.
According to another embodiment, an article of manufacture including a computer-readable medium, including a third party online coupon, a parsed description of what the third party online coupon covers, and evidence that the third party online coupon has been verified for a product associated with the parsed description.
Further embodiments, features, and advantages of the invention, as well as the structure and operation of the various embodiments of the invention are described in detail below with reference to the accompanying drawings.
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate embodiments of the invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the relevant art to make and use the invention.
The invention will now be described with reference to the accompanying drawings. In the drawings, generally, like reference numbers indicate identical or functionally similar elements.

The following detailed description refers to the accompanying drawings that illustrate exemplary embodiments consistent with this invention. Other embodiments are possible, and modifications can be made to the embodiments within the spirit and scope of the invention. Therefore, the detailed description is not meant to limit the invention. Rather, the scope of the invention is defined by the appended claims.
Coupons are a well understood technique to entice customers to a store. With the advent of computers and databases, coupons have become more powerful for merchants as the merchants can learn more about the behavior of the customers who use coupons, and can better target the coupons to offer their customers promotions that they will want.
However, online coupons have proven a uniquely frustrating experience because where printed coupons have the “fine print” on them detailing deadlines, exclusions and other restrictions, online coupons are often separated from these details. Online coupons are often entered with a code, such as JULY4SALE when checking out from a merchant. Online coupons are thus often stored and shared as merely the information needed to receive the discount. In turn, this means that potential customers cannot learn if an online coupon is valid until they are trying to check out. Merchants are concerned that rejecting a customer just as they are about to complete their purchase will not only dissuade the customer from making the purchase, it may alienate them over the longer term.
Conversely, customers know that they can save a significant amount of aggravation by using coupons that they know to be valid. Therefore, a system that notifies potential customers of valid coupons in advance of checking out would be welcome by both merchants and shoppers. Further, the more information can be provided before checking out, the better the customer will understand their options and the happier they are likely to be.
In this specification, the term “coupon” is to be interpreted broadly. “Coupon” is intended to encompass promotion codes, discount codes, referring links that entitle a shopper to improved treatment, such as a discount or a free item with purchase or other distributable information that can entice a shopper to a merchant via improved treatment. “Coupon” further includes deals, sales and other promotions, even where a customer does not need to present a code, piece of paper or other item.
An “online” coupon refers to a coupon that is submitted electronically, such as a promotion code. Online coupons can be distributed on paper, such as a mailing that instructs shoppers to enter a code, or visit a particular website.
A “third party” coupon refers to one that is distributed or otherwise interacted with by a party other than the issuer and the customer. If Macy's were to host coupons for its stores on macys.com, these would not be third party coupons. If that same coupon were hosted at zendeals.com, it would be a third party coupon because zendeals.com is not part of Macy's.
“Product” includes products and services, and is to be interpreted broadly. “Merchant” is also a broad term, and includes retailers and websites that a shopper might visit. Marketplaces, such as amazon.com and ebay.com are examples of merchants, as are independent operators who sell through amazon.com or ebay.com.
A “web interface” includes a webpage, a website, an email newsletter, a browser extension user interface, mobile app user interface, or other user interfaces that can be delivered through a network.
The coupon validation server 106 is coupled to the merchant server 102 via a network 104, such as the internet. The coupon validation server 106 includes a database of coupons to validate 121. The coupon validation server 106 also includes a database of coupon validation results 122. The coupon validation server 106 further includes a database of maps of various merchant websites 124, to be discussed in more detail below. A map is an example of a graph. The coupon validation server 106 also includes spiders 126 and computer robots 128, such as a webbot. The coupon validation server 106 includes website 130 that provides information about coupons. The coupon validation server 106 also includes a coupon response classifier 132. A coupon validation server is an example of a coupon validator.
The client 108 is coupled to both the merchant server 102 and the coupon validation server 106 via the network 104. Network 104 may be any network or combination of networks that can carry data communication. Such a network 102 may include, but is not limited to, a local area network, metropolitan area network, and/or wide area network such as the Internet. Network 102 can support protocols and technology including, but not limited to, World Wide Web (or simply the “Web”), protocols such as a Hypertext Transfer Protocol (“HTTP”) protocols, and/or services. Intermediate web servers, gateways, or other servers may be provided between components of the system shown in
Client 108 is a computing device that is under the control of a user and is capable of requesting and receiving resources over network 104. Client 108 can also be implemented in software, firmware, hardware, or a combination thereof on one or more computing devices at the same or different locations. As mentioned above, such a computing device can be any type of device having one or more processors and memory. For example, a computing device for client 108 can be a workstation, mobile device (e.g., a mobile phone, personal digital assistant, tablet or laptop), computer, server, computer cluster, server farm, game console, set-top box, kiosk, embedded system or other device having at least one processor and memory.
The client 108 may be operated by an individual who is considering an online purchase. The client 108 can navigate to the coupon validation website 130 and to the merchant's homepage 114. For example, client 108 can include an application, such as a web browser (or simply browser) through which a user can request resources from a website over network 104. A user requests a resource by typing the website address associated with the resources that is stored on a web server(s) over the web.
Another approach to gathering coupons may be to join an affiliate program, such as Commission Junction®. One advantage to using an affiliate program is that the coupons are provided in a variety of formats including but not limited to XML, CSV, or accessed through an API. Websites may be able to collect a commission on sales from customers who the website directs to the merchant website 110, and offering a coupon is one way to persuade browsers 108 of a web site to visit the merchant web site 110.
Affiliate programs may also distribute deals and sales. In certain cases, the deal or sale may be an upcoming one, whereas in other cases, the deal or sale may be currently underway. A customer 108 may qualify for a deal or sale at a merchant website 110 by making a qualifying purchase when the deal or sale is active.
Coupon distributors, such as retailers, are often interested in tracking coupon usage to, for example, be able to pay commissions. A successful purchase can be associated with a commission program participant when the participant directs the shopper to the merchant website via a uniform resource locator with tracking data embedded that specifies who should receive the commission. Sometimes the uniform resource locators include a redirect, such as through gan.doubleclick.net. The redirect allows the server which performs the redirect to place a cookie or perform other types of tracking. Another approach to tracking is to place a cookie on a shopper's computer when they receive the coupon. The merchant may in turn detect the cookie and know that a commission is due. Another approach is for a merchant server 102 to detect the referring website when the user 108 clicks a link on the referring website. Yet another approach is for the website providing the coupons to open a background window, or a pop-up window, when a visitor requests a coupon such that the merchant server 102 may detect this window in order to credit the website that the visitor started at. Combinations of these techniques may also be used. In certain cases, a merchant may pay the commissions directly, in other, a third-party, such as a coupon affiliate program operator, may pay the commissions.
At stage 204, the coupons can be associated with a merchant website 110 by coupon validation server 106. In one example, a spreadsheet or other data structure can be used to store associations between a coupon and a merchant website 110. If the coupons came from an affiliate program, the website where the purchase can be made can be included in a spreadsheet row with the discount code. A coupon validation server 106 may have a parser module to parse the spreadsheet. If the coupon was discovered by a spider 126, the merchant website 110 may be associated with the coupon when the spider 126 reports the coupon to the coupon validation server 106, because the spider 126 likely retrieved the coupon from the merchant's website 110. In other words, if a spider 126 finds a coupon while spidering target.com, the coupon validation server 106 may associate the coupon with Target, the merchant, whose web site is target.com. If a deal code is found in a Bed, Bath and Beyond promotional email, by a batch program on the coupon validation server 106, the coupon could be associated with www.bedbathandbeyond.com (though other systems may have a lookup table such that if a company moved its website, you could find the new uniform resource locator by looking up the company name in the table).
It may be easier to validate a coupon if it has been associated with a merchant website 110, because the association allows the coupon validation server 106 to know where to attempt to validate the coupon. This validation performed by coupon validation server 106 is described with respect to stages 206-214. If the goal is to validate an industrial quantity of coupons, such as millions of coupons or more than a hundred thousand, it may be advantageous to automate the process of validating coupons. One way to automate the process is to validate a coupon with a computer robot 128, dispatched from a coupon validation server 106, that navigates the merchant website 110, and attempts to apply the coupon. Often checkout pages 118 have a button that a user 108 or computer robot 128 can select to see if the coupon is valid. In certain instances, the checkout page 118 may display whether or not a coupon is valid after the user 108 or a computer robot 128 enters a return key, or allows a specified period of time to pass. Certain merchant servers 102 are allowing users 108 to test coupons earlier in the shopping experience, such as when viewing the contents of a shopping cart, to reduce future surprises for customers 108. The computer robot 128 may then process the page returned by the merchant's server 102 to determine if the coupon has been accepted, and is thus valid.
Given enough coupons to process, it may be advantageous to visit a merchant's website 110 with a spider 126 before employing the computer robots 128, in order to find the fastest route through the merchant's website 110 for the computer robots 128 to use. In certain situations, a human operator may manually determine an optimal route and then program this information into a computerized system.
Stage 206 is spidering the merchant website 110. This may start where the coupon validation server 106 directs a spider 126 to visit a home page 114, such as the landing page 116 of the merchant's domain. Upon reaching a page 120, the spider 126 may first determine if it is able to checkout, i.e., exercise a coupon, on that page 120. The spider 126 may then determine the potential exit paths from the current page 120. Often the exit paths will be accessible as links on the page. Other exit paths may be discovered in response to activating page elements, such as a button (e.g., “place in cart”). The spider 126 can use this information to build a graph of the merchant's website 110. The coupon validation server 106 may store the graph in the database of maps of various merchant websites 124.
In certain embodiments, the spider 126 may attempt to traverse the merchant's entire website 110. This may be accomplished using either a breadth first or depth first search of the website 110 according to the graph that the spider 126 builds as it traverses. It may be safe to assume that if a page 120 of the merchant's website 110 is not accessible by following links, it is unlikely to be a checkout page 118. Once the entire website 110 has been spidered, one way to find an optimal route may be to conduct a breadth first search of the graph and stop upon reaching a checkout page 118.
When spidering a merchant website 110, it may be advantageous to avoid creating loops in the graph of the merchant website 110, such that a later traversal of the graph cannot result in traveling in an endless loop. One way to avoid loops when spidering a merchant's website 110 is to not follow an exit path to a webpage 120 that has been previously visited (the spider 126 may return to a webpage after spidering a subsection of the website 110, but not via an exit path. For instance, a spider 126 may find a webpage 120 with three exit paths. After exploring the first exit path, the spider 126 may return to explore the second exit path without creating a loop because the spider 126 will not create a link in the graph back to the webpage 120). More sophisticated algorithms may also be used, such as Kosaraju's algorithm, Tarjan's algorithm and the path-based strong component algorithm.
Another approach to determining a preferred route through a merchant's website 110 is to develop Bayesian networks describing the website 110. Each node in the network could correspond to a page 120 in the website 110, and each edge between nodes could correspond to an exit path. The higher the score applied to the edges, the more optimal the edge, or exit path, is believed to be in quickly reaching a checkout page 118. A spider 126 may thus traverse the merchant's website 110, and then upon reaching a checkout page 118, divide one by the number of edges followed to arrive at the checkout page 118, and add this value to each of the edges (a website 110 where the homepage 114 is also a checkout page 118 is a trivial corner case). Over time, the fastest path to a checkout page 118 is likely to emerge. In certain embodiments, scores may be deprecated over time, for example, discounted by 10% every six months. Such an approach may help the Bayesian network adjust to merchant websites 110 that periodically alter their layout to move checkout pages. Additional disclosure about spidering a merchant's website may be found in U.S. application Ser. No. 13/307,586, filed Nov. 30, 2011 and entitled “Promotion Code Validation Apparatus and Method,” which is herein incorporated by reference in its entirety.
It may be advantageous to discover not only if a coupon is valid, but also which products it covers. One way to do this may be for a computer robot 128 to try putting each item available from a merchant's website 110 into a shopping cart and applying the coupon to each item individually and removing the item before adding the next one to the shopping cart. Such an approach may be computationally intensive. It may be advantageous to stop after detecting a product that is covered by the coupon. In another embodiment, it may be desirable to determine all products that the coupon may cover. It may be advantageous to validate coupons against products which are more likely to be covered in an effort to reduce the amount of computational resources (including bandwidth) required. Text that is included in, or associated with, a coupon code is part of the “coupon description,” may provide clues as to which products are likely covered by the coupon. An example of a coupon description may be the text provided by a coupon distributor, such as a retailer or coupon aggregator. Another example of a coupon code description may be text that has been laid out around the discount code on a website.
Stage 208 is to parse a coupon for product terms. One approach may be for a coupon validation server 106 to instruct a parser module to parse the coupon's text for product terms, and then direct a computer robot 128 to search the merchant website 110 for the product terms. The parser module may include a lexer to perform a lexical analysis of the coupon text. One embodiment of the coupon validation server 106 may employ a natural language processing module to determine which words in the coupon's text are most likely to be fruitful for searches. Consider the phrase “10% off of all Lego toys in March!” One technique that may be employed by a natural language processing module is to remove noisy words, such as “of,” “in”, “the”, “save”, “off” because these terms are so unlikely to be useful keywords. Another technique is to remove words from a corpus, such as terms that are frequently used in describing sales, such as “limited,” “only,” “today,” “hurry,” “Black Friday,” and various holidays, occasions for gift giving (e.g., graduation), days, months, years or other terms that regularly appear in sales copy. Another technique is for the coupon validation server 106 to reference a database of all known brands, and then instruct the natural language processing module to extract those terms from the coupon description. This way, a natural language processing module can know that Armani® is likely a product term.
Another technique to parse a coupon for product terms that a natural language processing module might be configured to perform may be to perform sentence recognition, to understand which parts of a sentence are most likely to be describing the product. This technique may be performed by a lexer in the natural language processing module. Such a lexer may employ orthographic techniques to identify the sentence, as the author of coupon may not have used a complete sentence. An orthographic technique, in English, includes starting from a capitalized letter and continuing to a full stop, such as a period or exclamation mark (though algorithms are often more complicated, in order to correctly parse abbreviations, for example). Because coupons may not employ periods at the end of a sentence, certain whitespace may be recognized as a full stop. Sentence recognition may seek to identify the subjects and objects of a sentence as these are more likely to be useful keywords in describing the covered product (or product category). The position of a word in the sentence may also play a role.
Another technique to parse a coupon for product terms may be to identify irregular capitalization (because brand names are more likely to be capitalized) or words followed by a registered trademark symbol (®). Though each of the above approaches may be used individually, they may also be used in combination.
Step 210 is to identify a product that matches a product term, such as by a coupon validation server 106. One way to do this is for a computer robot 128 to use a merchant website's search feature to search for corresponding products by entering the product terms as search terms. The product terms may be entered by the computer robot 128 into the merchant's search feature individually or as a group. In certain embodiments, the coupon validation server 106 may have assigned confidence scores to product terms when the product terms were extracted by the parser module, such that the product terms with the highest confidence are searched first. For many merchant websites 110, the search box appears on every page 120. The search box is coupled to the search database 112 and may serve as a gateway interface to allow a client 108 to execute queries against the search database 112. Therefore, the search box may often be found on the homepage 114, without needing to spider the merchant's website 110. Another approach is to use an external search engine, such as Google®, to search for the product terms while restricting the search to the merchant's website 110, perhaps with search terms such as [site:merchant.com legos]. A specialized shopping search engine, such as Froogle® may also be employed.
Once a page of search results 120 has been generated by the merchant server 102, there are additional steps before the computer robot can place the listed search results in a shopping cart on the merchant website 110. One: way to retrieve a page of search results 120 is for a computer robot 128 to download the webpage 120 and pass it to the coupon validation server 106. Another way is for the coupon validation server to download the page of search results 120. The coupon validation server 106 may also retrieve the information from product feeds. In some instances, merchant servers 102, such as Amazon.com, provide product feeds. In other instances, companies like pricegrabber.com provide product feeds. Information that may be of interest to a coupon validation server 106 from a product feed includes the uniform resource location, images of the product, product details, product price, and product specifications. The page of search results 120 may be parsed by a parser module on the coupon validation server 106, or the parser module may be included in a computer robot 128, for links that correspond to search results under the theory that these links lead to product pages 120, where the products can be added to a shopping cart on the merchant website 110. In one embodiment, a different computer robot 128 may be dispatched by the coupon validation server 106 for each product to search. For example, if the product term “soccer” is searched, the merchant server 102 might return a webpage 120 with ten results for “soccer,” including items such as soccer balls, soccer jerseys and/or soccer shorts. The coupon validation server 106 may then dispatch ten computer robots 128, each one set to add a different “soccer” product to their respective shopping cart and then validate the coupon against their respective product. If a coupon validates with a given product, the computer robot 128 may report back to the coupon validation server 106 that the coupon it was assigned covers the product that it was assigned.
Stage 212 is for computer robot 128 to check out with a coupon. The computer robot 128 navigates to the checkout page 118, as described above. The computer robot 128 retrieves a copy of the webpage presenting the costs, such as a checkout page 118. The computer robot 128 applies the coupon. In some embodiments, the coupon may already be applied, such as if the computer robot 128 were referred to the merchant's website 110 via uniform resource locator with tracking information associated with a coupon. In some embodiments, the computer robot 128 may enter a coupon code into a textbox on a checkout page 118, and then activate a button or other item to enter the coupon. In certain embodiments, the coupon validation server 106 may have previously provided a coupon code to the computer robot 128 from the database of coupons to validate 121. If the coupon code was not automatically applied, e.g., by way of a referring uniform resource locator, the computer robot 128 saves a copy of the checkout page 118 before the coupon has been applied.
Stage 214 is for a coupon response classifier 132 to determine if the coupon was accepted. The computer robot 128 saves a copy of the checkout page 118 after the coupon has been entered. In one embodiment, the computer robot 128 may process the checkout page 118 itself. In another embodiment, the coupon validation server 106 may process the checkout page 118. One approach to processing the checkout page 118 is to compare the before and after versions. Under this approach, page elements, such as text and images, that are the same in both copies 118 are stripped out by a natural language processing module. A final price may be identified by the coupon validation server 106, such as by searching for the largest number adjacent to a dollar or other currency sign, or for an amount placed near a term such as “price,” “total” or an extended line, as is used in arithmetic for summations of a vertical list of summands. Even where a final price cannot be definitively identified, it may be possible to determine if the numbers in the “after” version of the checkout page 118 are lower than the numbers in the same place of the “before” checkout page 118. If so, it may be determined that the coupon was accepted.
Another approach to determining if the coupon was accepted by the merchant server 102 is to search the “after” checkout page 118 for terms or phrases associated with successfully entering a coupon, such as “discount applied,” “congratulations,” “success,” or “new price.” Conversely, the checkout page 118 may be searched by a coupon response classifier 132 on the coupon validation server 106 for terms or phrases associated with a coupon that was not entered successfully, such as “sorry,” “error,” “expired,” “unrecognized,” or “try again.” The technique of searching a checkout page 118 for terms indicating success or failure may be applied by a coupon response classifier 132 to a checkout page 118 even if there. was not a “before” version.
Certain coupon response classifiers 132 may determine more than just if the coupon was accepted. One coupon response classifier 132. may be configured to determine changes in price, such as the total price, the price of a product, shipping price and other amounts that a customer 108 may be charged. Such a coupon response classifier 132 would determine an original price from a “before” checkout page 118. The coupon response classifier 132 may search the source code of a checkout page 118 for a corpus of price related terms, such as “price,” “total,” “shipping” “tax,” “taxes,” “subtotal,” or “handling.” Certain coupon response classifiers 132 may associate the discount with a basis, such as detecting that the discount is a discount on shipping or a particular item. A coupon response classifier 132 may be configured to specifically check for free shipping, such as by searching for a shipping charge that appears in a “before” checkout page 118 but not in an “after” checkout page 118, or by searching for terms such as “free shipping.”
A coupon response classifier 132 may have a module to find prices in a checkout page 118, which may be useful for measuring price changes. The coupon response classifier 132 may also search for a dollar sign, or other currency symbol, or may perform regular expression parsing to find a dollar sign followed by a number. Another coupon response classifier 132 may perform regular expression parsing to detect a number followed by a period with two digits following the period, such as $5.00). The coupon response classifier 132 may then compare the values from the “before” and “after” checkout pages 118 to determine a change in price. Another coupon response classifier 132 may search an after page for information regarding an applied discount, such as by searching for ‘%’ or terms such as “discount” or “taken off” Such a coupon response classifier 132 may retrieve nearby numerical values to determine if the “after” checkout page 118 has recorded a percentage discount (likely expressed as two digits followed by a percentage sign) or an amount of a discount, detected as a dollar amount, as discussed herein.
Another coupon response classifier 132 may determine if the “after” checkout page 118 has more items than a “before” checkout page 118, as may be the case where a free gift is included with purchase. Such a coupon response classifier 132 may search for terms such as “item,” “added,” “free,” or “new.” Another coupon response classifier 132 may search for new items in an enumerated list, particularly where the layout of the “after” checkout page 118 suggests that the enumerated list is relevant. Examples of relevancy may include being near a detected price, being part of the same hypertext markup language table as the price, being in the primary frame of the checkout page 118 and being in a font associated with checking out, such as bold with dark colors. If no “before” checkout page 118 is available, a coupon response classifier 132 may compare the number of items detected in the “after” checkout page 118 to the number of items the computer robot 128 reported adding to the shopping cart.
In certain embodiments, a checkout page 118 may be marked as “indeterminate,” such as if neither the success or failure algorithm produced a reliable result. A coupon validation server 106 may periodically review the “indeterminate” checkout pages 118 to reconsider them, perhaps in light of an updated corpus of terms. In another embodiment, “indeterminate” checkout pages 118 may be reviewed manually. The results, success, indeterminate or failure, may then be stored in the database of coupon validation results 122.
The techniques for processing a third party coupon may also be applied to a coupon being promoted by a coupon validation server 106 on its website 130 where the coupon validation server 106 is operated by the merchant. Presently, merchants may issue coupons but do not have a reliable way of tracking what the parameters for a customer 108 to use the coupon. In such a situation, the coupon validation server 106 could be part of a merchant server 102.
Certain embodiments of the method
Stage 302 is for a computer robot 128, having been dispatched by a coupon validation server 106, to go to a merchant website 110. It may be advantageous to wait until the page has loaded completely. In one embodiment, the computer robot 128 may opt to not load any images, in order to improve speed and reduce bandwidth consumption.
Stage 304 is for the computer robot 128 to log in to merchant website 110. Logging in to the merchant's website 110 is often necessary to add products to a shopping cart on the merchant website 110. Certain websites allow a “guest checkout,” i.e., a shopper can make a purchase without needing to log in, and thus a computer robot 128 can validate a coupon without logging in to the merchant website 110. In such an embodiment, stage 304 is optional. In certain embodiments, a coupon validation server 106 will have instructed the computer robot 128 whether logging in is necessary. In certain embodiments, a coupon validation server 106 will provide customer account details to the computer robot 128 in order to log in.
Stage 306 is for a computer robot 128 to add a selected item to a shopping cart of the merchant website 110. If the computer robot 128 logged in, it may be advisable to clear the shopping cart, to ensure that there is not an item in there from a previous validation effort. As described above, this computer robot 128 may be one of many computer robots 128 tasked with validating that a coupon applies to a variety of products. Therefore, it may be important for this computer robot 128 to put a particular item in its shopping cart such that the coupon validation server 106 can know that the coupon validation result returned by this computer robot 128 corresponds to the intended product. In other words, if the coupon validation server 106 wishes to test 10 products, and assigns 10 computer robots 128 to the task, it is important that each computer robot 128 validate that the coupon applies to the intended product, e.g., the third computer robot 128 validates that the coupon applies to the third product.
The computer robot 128 may have specific instructions as to which product should be added to the shopping cart on the merchant website 110. One way to specify this is for the coupon validation server 106 to provide the computer robot 128 with a search string and a result to select, e.g., search for [superman action figure] and select the fifth result. Another way to specify this is for the coupon validation server 106 to provide the computer robot 128 with a uniform resource locator for the selected product's product page 120. The computer robot 128 could then navigate to the product page 120 and add the displayed item to the shopping cart. After completing this stage 306, the computer robot 128 should be confident that it has one product in its shopping cart, the selected product.
Stage 308 is for the computer robot 128 to checkout from the merchant website 110 with a coupon. Each dispatched computer robot 128 proceeds to the checkout page 118 and attempts to validate the coupon using techniques similar to those described with respect to stage 212.
Stage 310 is for the coupon response classifier 132 to determine if the coupon was accepted by the merchant server 102. The computer robot 128, or the coupon validation server 106, will validate the coupon by determining if it was accepted using techniques similar to those described with respect to stage 214, such as employing a coupon response classifier 132.
Stage 312 is for the coupon validation server 106 to synthesize validation results. Reports from computer robots 128 that have completed a checkout process can be communicated back to the coupon validation server 106. If a coupon response classifier 132 on either the computer robot 128 or the coupon validation server 106 determines that a coupon was not accepted, the coupon validation server 106 may write this information to the database of coupon validation results 122. In scenarios where none of the computer robots 128 find a valid coupon, the coupon validation server 106 may write to the database of coupon validation results 122 that the coupon is invalid, and not proceed to test it further, as few coupons transition from being invalid to valid. In some instances, the coupon validation server 106 may write to the database of coupon validation results 122 that the coupon is invalid for this merchant, but designate that the coupon should be tested at other merchant websites 110, such as those of a competitor.
When a coupon is detected as valid, the coupon validation server 106 may write this information to the database of coupon validation results 122. In another embodiment, the coupon validation server 106 may wait until it has received reports from all of the computer robots 128 before writing a result to the database of coupon validation results 122. One advantage of this approach is that the coupon validation server 106 may be able to detect patterns of the validated versus invalidated coupons to learn, for instance, that the coupon covers all men's clothing, that the coupon is only valid at certain times, that the coupon is only valid on purchases more than $100 or other restrictions on the coupon's use. In other embodiments, the coupon validation server 106 may command other computer robots 128 to cease after a first computer robot 128 successfully uses the commonly assigned coupon, to reduce the required computational resources.
As a final step in synthesizing the coupon validation results, the coupon validation server 106 may update its webpage 130 with the results so that potential shoppers may visit the website 130 to learn the latest validation results, so that they may efficiently receive discounts and other promotions in a hassle free manner.
