Abstract:
Competitors are classified in terms of products the competitors offer. A product set is generated from product information received from a user. Also, a competitor set is generated, where the competitor set comprises at least one competitor determined to be relevant to one or more products in the product set. A target price rule is generated that is operative to change a price offered by the user for the at least one product. A competitors relevancy can be determined by considering factors such as: (1) unique visitors to the competitor&#39;s website, (2) reviews on the competitor&#39;s website (3), ratings on the competitor&#39;s website, (4) absolute number of products common to the user&#39;s website and the competitor&#39;s website, (5) percentage number of products common to the user&#39;s website and the competitor&#39;s website, and (6) number of products offered by the competitor that comprise the product set.

     TECHNICAL FIELD 
       [0002]    This disclosure relates generally to the field of competitive intelligence, and specifically to product assortment in the retail industry. 
       BACKGROUND 
       [0003]    Competitive intelligence, as it relates to pricing, has been an important aspect of the retail business for decades. Today, consumers have tools that allow them to compare prices across thousands of retailers in seconds. 
         [0004]    To be competitive, retailers today must: i) know who their competitors are, ii) know how much their competitors are charging for the goods that they carry, and iii) be able to act on this information. 
         [0005]    Many retailers carry a very large number of products on their catalog, often times in excess of 100,000 different stock keeping units (SKUs) associated with different products. Each SKU is often sold by many different competitors at different prices. Competitors may change their prices for products at any time, which makes it even more difficult to determine the pricing of the products at different retailers. 
         [0006]    Because of the large number of retailers selling goods online, it can be important that retailers know who their relevant competitors are; not only at the store level, but also at the “product group” level. “Product group,” in this case, can be defined as a group of SKUs or other product identifiers. A “product group” can be a product category (e.g., digital cameras), a brand (e.g., Canon® products), or any pre-defined product group (e.g., high-end Canon® digital cameras). 
       SUMMARY 
       [0007]    An objective of the present disclosure is to provide competitive intelligence related to classifying competitors for a retailer. Another objective of the present disclosure is to help retailers know who their competitors are for any given product-group. These and other objectives can be achieved in embodiments disclosed herein. In particular, embodiments may determine if an online retailer is a potential competitor for a pre-defined product group. Relevancy may be determined, for instance, by looking at product overlap, estimated traffic, average rating of online reviews, and a number of views for a website associated with the potential competitor. A product group may be products in a product category, brand, in a user-defined product group, etc. 
         [0008]    In embodiments, a system may determine web pages for competitors that include relevant products to a customer of the system. One example of such a customer may be a business entity. One example of a business entity can be a retailer. This retailer may be selling a product and is interested in information relating to that product or similar ones from its competitors, including known and unknown competitors. These competitors may have a presence on the Internet. The system may be configured to pull information associated with products or product types from an unbound number of domains on the Internet. Examples of information associated with a product may include name, description, product attributes, SKU, price, image, etc. These competitors as well as their domains and websites may or may not be known by a customer requesting the information. 
         [0009]    In this disclosure, the term “domain” is used in the context of the hierarchical Domain Name System (DNS) of the Internet. Those skilled in the art appreciate that the DNS refers to a hierarchical naming system for computers or any resource connected to the Internet. A network that is registered with the DNS has a domain name under which a collection of network devices are organized. Today, there are hundreds of millions of websites with domain names and content on them. As the number of websites continues to grow, pulling information associated with a product or products from an unbound number of domains on the Internet can be a very complex, tedious, and complicated process. 
         [0010]    Embodiments disclosed herein can leverage wrapper induction and wrapper infection methodologies disclosed in Appendix A and Appendix B attached herewith to automate a data mining process across unbounded domains. Additionally, because each competitor may describe or define a product in different ways, it may be desirable or necessary to determine which products sold by different competitors refer to the same product. Embodiments disclosed herein can also leverage a novel approach disclosed in Appendix C attached herewith to match a product or product type of interest with product information crawled from the Internet. This matching process can help to ensure that any price or feature comparison made between a predefined product/product type and products/product types being sold by different competitors on the Internet are the same and/or relevant. Appendices A, B, and C are hereby incorporated by reference in their entireties. 
         [0011]    In embodiments disclosed herein, a system is operable to obtain or otherwise gain knowledge on the products that competitors are selling and each competitor&#39;s pricing of the products. The system includes a user interface through which a customer can identify what products that the customer carries. In one embodiment, a customer can provide the system with a product catalog through the user interface or via other means. 
         [0012]    The system may include a competitor classifier operable to determine what other retailers (potential or actual competitors of the customer of the system) are selling the same products and how much they are selling the products for. The competitor classifier may identify a retailer as a potential competitor of the customer. For each potential competitor, the competitor classifier may determine the following variables: (1) an estimated number of unique visitors to the potential competitor&#39;s website; (2) a number of user-reviews that the potential competitor has; (3) a review-rating associated with the potential competitor; (4) a percentage of product that overlap between a product group of the customer and the potential competitor (e.g., the potential competitor carries 80% of the same digital cameras products carried by the customer); and (5) a number of products that the potential competitor&#39;s product group overlaps with the customer&#39;s product group (e.g., the potential competitor carries 500 of the same digital cameras products carried by the customer). 
         [0013]    Those skilled in the art will appreciate that the above list of variables is meant to be illustrative and that other variables may also be determined. In some embodiments, each variable may be associated with a weight. In some embodiments, the variables may be computed, weighted, added, and normalized to generate a value. In some embodiments, the generated value may be a number between 0 and 100. In some embodiments, if the generated value is above a configurable threshold (e.g., 60%), then the potential competitor may be considered a relevant competitor for the product group of interest. 
         [0014]    Embodiments can provide many advantages. For example, although retailers often know who their top competitors are, it is difficult to determine who their relevant competitors are for each one of their product groups. This method allows a retailer to know who their top competitors are for each one of their product groups. With this information in hand, retailers can create pricing rules for a certain product group against the competitors that are relevant for that product group. For example, while a company may have many competitors for their store in general, in a particular product group such as digital cameras, they may be competing with many niche stores that specialize in digital cameras. Knowing who their competitors are allows the company to create effective, targeted pricing rules. 
         [0015]    These, and other aspects will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. The following description, while indicating various embodiments and numerous specific details thereof, is given by way of illustration and not of limitation. Many substitutions, modifications, additions or rearrangements may be made within the scope of this disclosure, which includes all such substitutions, modifications, additions or rearrangements.

     DETAILED DESCRIPTION 
       [0021]    Various features and advantageous the present disclosure are explained more fully with reference to the nonlimiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known starting materials, processing techniques, components and equipment are omitted so as not to unnecessarily obscure the present disclosure. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments, are given by way of illustration only and not by way of limitation. Various substitutions, modifications, additions and/or rearrangements within the spirit and/or scope of the underlying inventive concept will become apparent to those skilled in the art from this disclosure. Embodiments discussed herein can be implemented in suitable computer-executable instructions that may reside on a computer readable medium (e.g., a hard disk (HD)), hardware circuitry or the like, or any combination. 
         [0022]    Before discussing specific embodiments, a brief overview of the context of the disclosure may be helpful. Embodiments of systems and methods described herein may determine if an online retailer is a potential competitor for a customer in a particular product group (e.g., a product group defined by the customer using, for instance, SKUs or other product identifiers). A product group may include products in a product category, brand, in a user-defined product group, etc. Relevancy of potential competitors may be determined, for instance, by looking at product overlap, estimated traffic, average rating of online reviews, and a number of views for a website associated with a potential competitor. By knowing who their competitors are for a product group of interest, a retailer may create targeted pricing rules for the product group. 
         [0023]    Turning now to  FIG. 1 , a block diagram illustrating an exemplary system  100  is shown. System  100  couples to a network such as the Internet  101  and has access to domains  110   a  . . .  110   n.  Each domain may have a common network name (domain name) under which a collection of network devices are organized (e.g., domain.com). Each domain may have one or more sub-domains (e.g., abc.domain.com, xyz.domain.com, etc.) according to the hierarchical Domain Name System (DNA) of the Internet. The collection of network devices in a domain may include one or more server machines hosting a website representing the domain (e.g., www.domain.com). 
         [0024]    A website (also referred to as Web site, web site, or site) refers to a set of related web pages (also referred to as pages) containing content such as text, images, video, audio, etc. A website can be accessible via a network such as the Internet or a private local area network through an Internet address known as a Uniform Resource Locator (URL). All publicly accessible websites collectively constitute the World Wide Web. 
         [0025]    Crawler  130  of system  100  may crawl the Internet  101  across domains  110   a - 110   n  for data and store them in raw data database  140 . The data obtained by crawler  130  may be associated with retail products. Wrappers  160  may be generated using techniques disclosed in Appendix A and/or Appendix B to extract desired information, such as domain product and price information, from the raw data obtained by crawler  130 . Other suitable wrapper generation techniques may also be used. The domain product and price information thus obtained may be stored at database  170 . 
         [0026]    System  100  may include competitor classifier system or module  150 . Functionality of this feature will now be described in detail. Competitor classifier module  150  may be configured to receive a user defined product group and determine who are the relevant competitors associated with the product group. The relevant competitors for the product group may be determined based on weighted variables associated with a number of unique visitors that the competitor&#39;s website has over a time period, a number of reviews and review ratings of the competitor&#39;s website, a number of overlapping products that the retailer and a competitor carry, a percentage of overlapping products that the retailer and a competitor carry etc. 
         [0027]    The number of unique visitors that a competitor&#39;s website has may be obtained from a data source or website communicatively connected to system  100 . An example data source or website that provides this type of information may be www.compete.com. Likewise, the number of reviews and the review ratings associated with a potential competitor&#39;s website may be obtained from a data source or website. An example data source or website that provides this type of information may be www.google.com. In some embodiments, the number and percentage of overlapping products that a retailer and their competitor(s) carry may be determined utilizing embodiments described in the attached Appendices A, B, and C, which form part of this disclosure. 
         [0028]    In one embodiment, each of the variables may have a relative weight. In one embodiment, the variables may be weighted, added together, and normalized to produce a value indicating relevancy. If the relevancy value is above a certain threshold, then the potential competitor may be considered a relevant competitor for the product group of interest. An example threshold may be 60. 
         [0029]      FIG. 2  depicts one embodiment of a table  200  associated with a product group of interest for a potential competitor. Table  200  may include variables such as the product percentage overlap  210 , the number of visitors  215  the potential competitor&#39;s website had over a period of time, the number of reviews  220  the competitor&#39;s website had, the average of the reviews  225 , and the product overlap count  230 . 
         [0030]    Each of the variables may have different threshold ranges  235  with respective weights  240 . In one embodiment, product percentage overlap variable  210  may have thresholds ranges  235  associated therewith if a potential competitor has a product overlap of 0-10%, 10-20%, 60-100%, etc. Based on which threshold range  235  a competitor should be classified for a particular variable and the weight  240 , a total number of points  237  may be determined for a potential competitor for that variable. For example, as shown in  FIG. 2 , a potential competitor may have a product percentage overlap  210  in the range of 60-100% and the weight  240  for that threshold range  235  may be four. Therefore, the potential competitor may be assigned a total number  237  of four points for the percentage overlap variable  210 . 
         [0031]    This calculation is performed for each of the variables  210 ,  215 ,  220 ,  225 , and  230  to generate a total number  237  for each variable. The total numbers  237  are then added to produce a total score points  250 . The total score  250  is computed relative to the maximum possible score points  255  to generate a relevancy score  260 . If the relevancy score  260  is higher than a relevancy threshold  265 , then the potential competitor is considered a relevant competitor and displayed accordingly in box  270 . 
         [0032]    Accordingly, total point score  250  may represent a summation of points score  237  for each weighted variable. Max score  255  may represent a summation of the highest possible point score of the weighted variables for a potential competitor. Relevancy score  260  may represent how relevant a potential competitor is, and may be based on max score  255  and point score  250 . In one embodiment, relevancy score may be determined by dividing point score  250  by max score  255 . 
         [0033]    Relevancy threshold  265  may be a threshold associated with the relevancy of a potential competitor. If a potential competitor has a relevancy score  260  above relevancy threshold  265 , then relevancy indicator  270  may indicate that the potential competitor is a relevant competitor for the product group. If the potential competitor has a relevancy score  260  below relevancy threshold  265 , then the relevancy indicator  270  may indicate that the potential competitor is not a relevant competitor for the product group. 
         [0034]    One skilled in the art will appreciate that threshold ranges  235 , weights  240  for threshold ranges  235 , relevancy score  260 , and/or relevancy threshold  265  may be determined based on a desired configuration for a product group and may vary from implementation to implementation. 
         [0035]    In one embodiment, each variable may include a disqualifier  245 , where if the potential competitor has a variable in a certain disqualified range or value, then the potential competitor is automatically disqualified from being a relevant competitor, even if the potential competitor&#39;s relevancy score  260  is above the relevancy threshold  265 . For example, in one embodiment, if the product overlap variable is between 0-10% (i.e., there is no or little overlap of products in the product group), then the potential competitor may be automatically disqualified from being a relevant competitor. 
         [0036]    Now that relevant competitors are determined,  FIG. 3  depicts an example user interface  300  through which relevant competitors can be compared according to one embodiment. User interface  300  may include a table  310  with entries associated with a product group  320  for a retailer (e.g., customer  102  of system  100 ). In one embodiment, the product group  320  may be monitors. For each entry  320  in table  310 , user interface  300  may include data associated with how many products the retailer carries for the product group, a number of relevant competitors the retailer has in the product group, etc. An authorized user of the customer may be able to select, via user interface  300 , the relevant competitors in product group  320  to view further information associated with the relevant competitors. This is further illustrated in  FIG. 4 . 
         [0037]    As shown in  FIG. 4 , a user interface  400  implementing an embodiment of competitor classifier module  150  may provide data associated with a product group  410  for a retailer. In one embodiment, product group  410  may be monitors, and user interface  400  may provide data associated with product group  410 , including, but are not limited to, a number of products (e.g., identified by SKUs) a customer carries for product group  410 , a number of relevant competitors the customer has in product group  410 , relative price index in product group  410 , profit margin for product group  410 , etc. An authorized user of the customer may be able to select, via user interface  400 , the relevant competitors that the customer has in product group  410  to view further information associated with the relevant competitors. In the example of  FIG. 4 , the customer has 35 relevant competitors, as determined by an embodiment of competitor classifier module  150 .  FIG. 5  depicts a user interface  500  providing further information associated with such relevant competitors. 
         [0038]    As illustrated in  FIG. 5 , a customer may have a set of relevant competitors (e.g.,  35 ) in a product set (e.g., product category  510 ). A list of top relevant competitors in product category  510  may be generated and displayed via user interface  500  to authorized user of the customer. User interface  500  may include various information such as the relevancy scores of the relevant competitors, names of the relevant competitors, a relevancy index associated with how relevant a competitor is, etc. 
         [0039]    User interface  500  may also include additional information such as a product overlap associated with products that the relevant competitors carries and the products in the product group, a number of unique visitors that the relevant competitor&#39;s website has over a time period, a number of reviews associated with the competitor&#39;s website, and the average rating of the reviews associated with the competitor&#39;s website that are used to determine the competitor&#39;s relevancy score. 
         [0040]    By determining what competitors are relevant competitors for a product set, a retailer may determine the products for a product group of interest, determine products that relevant competitors carry that the retailer does not, determine what products the retailer carries that the relevant competitors do not, etc. This can help the retailer to refine their product offerings and further improve their bottom line, thereby becoming more competitive in each product group of interest. 
         [0041]      FIG. 6  depicts an example flow chart  600  illustrating an embodiment of a method for determining relevant competitors for a product group of interest to a retailer. 
         [0042]    At step  610 , a weighted variable associated with a number of unique visitors that a potential competitor&#39;s website had over a time period may be determined. 
         [0043]    At step  620 , a weighted variable associated with the number of user-reviews that the potential customer&#39;s website has may be determined. 
         [0044]    At step  630 , a weighted variable associated with the average rating of the user-reviews that the potential customer&#39;s website has may be determined. 
         [0045]    At step  640 , a weighted variable associated with the percentage overlap between the products within the product group and the products the potential competitor carries. 
         [0046]    At step  650 , a weighted variable associated with the number of the products within the product group that the products the potential competitor carries. 
         [0047]    At step  660 , the weighted variables may added together to determine a relevancy score. 
         [0048]    At step  670 , the relevancy score may be compared to a relevancy threshold to determine if the potential competitor is a relevant competitor.

The control logic may be stored in an information storage medium, such as a computer-readable medium, as a plurality of instructions adapted to direct an information processing device to perform a set of steps disclosed in the various embodiments. Based on the disclosure and teachings provided herein, a person of ordinary skill in the art will appreciate other ways and/or methods to implement the described embodiments. 
         [0057]    It is also within the spirit and scope of the disclosure to implement in software programming or code an of the steps, operations, methods, routines or portions thereof described herein, where such software programming or code can be stored in a computer-readable medium and can be operated on by a processor to permit a computer to perform any of the steps, operations, methods, routines or portions thereof described herein. Various embodiments may be implemented by using software programming or code in one or more general purpose digital computers, by using application specific integrated circuits, programmable logic devices, field programmable gate arrays, optical, chemical, biological, quantum or nanoengineered systems, or components and mechanisms may be used. In general, the functions of various embodiments can be achieved by any means as is known in the art. For example, distributed, or networked systems, components and circuits can be used. In another example, communication or transfer (or otherwise moving from one place to another) of data may be wired, wireless, or by any other means. 
         [0058]    A “computer-readable medium” may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, system or device. The computer readable medium can be, by way of example only but not by limitation, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, system, device, propagation medium, or computer memory. Such computer-readable medium shall generally be machine readable and include software programming or code that can be human readable (e.g., source code) or machine readable (e.g., object code). Examples of non-transitory computer-readable media can include random access memories, read-only memories, hard drives, data cartridges, magnetic tapes, floppy diskettes, flash memory drives, optical data storage devices, compact-disc read-only memories, and other appropriate computer memories and data storage devices. In an illustrative embodiment, some or all of the software components may reside on a single server computer or on any combination of separate server computers. As one skilled in the art can appreciate, a computer program product implementing an embodiment disclosed herein may comprise one or more non-transitory computer readable media storing computer instructions translatable by one or more processors in a computing environment. 
         [0059]    A “processor” includes any, hardware system, mechanism or component that processes data, signals or other information. A processor can include a system with a general-purpose central processing unit, multiple processing units, dedicated circuitry for achieving functionality, or other systems. Processing need not be limited to a geographic location, or have temporal limitations. For example, a processor can perform its functions in “real-time,” “offline,” in a “batch mode,” etc. Portions of processing can be performed at different times and at different locations, by different (or the same) processing systems. 
         [0060]    It will also be appreciated that one or more of the elements depicted in the drawings/figures can also be implemented in a more separated or integrated manner, or even removed or rendered as inoperable in certain cases, as is useful in accordance with a particular application. Additionally, any signal arrows in the drawings/figures should be considered only as exemplary, and not limiting, unless otherwise specifically noted. 
         [0061]    As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, product, article, or apparatus that comprises a list of elements is not necessarily limited only those elements but may include other elements not expressly listed or inherent to such process, process, article, or apparatus. 
         [0062]    Furthermore, the term “or” as used herein is generally intended to mean “and/or” unless otherwise indicated. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). As used herein, including the claims that follow, a term preceded by “a” or “an” (and “the” when antecedent basis is “a” or “an”) includes both singular and plural of such term, unless clearly indicated within the claim otherwise (i.e., that the reference “a” or “an” clearly indicates only the singular or only the plural). Also, as used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
