System and method of mapping product attributes between different schemas

Abstract

A system is described for mapping product attributes between schemas of e-commerce websites. Using a pre-defined reverse mapping, a mapping server populates a master attribute table from product attributes and taxonomy categorizations defined in a source schema. Using a pre-defined assignment mapping, the mapping server maps the master attributes in the master attribute table to product attributes and taxonomy categorizations in the target schema.

BACKGROUND

1. The Field of the Present Disclosure

The present disclosure relates generally to electronic commerce (“e-commerce”).

2. Description of Related Art

Business conducted over the Internet, referred to as e-commerce, has grown dramatically with the proliferation of consumer electronic devices. For example, online enterprises conduct e-commerce with users through e-commerce websites made available on a network, such as the Internet.

To assist users in locating desired products, e-commerce websites often organize products using taxonomies. Taxonomies are ordered classifications of information, which may be used for organizing information in a way that makes it more accessible for retrieval. The typical form of a taxonomy is hierarchical. For example, at the top levels of a hierarchy, general terms are used to describe the information. Beneath the top levels, more descriptive terms that refine the top-level terms are used. As such, a hierarchical taxonomy may be represented as a tree of information nodes, in which each node inherits all of its predecessors' attributes, and descriptive terms and other forms of metadata may be used to identify the nodes. On an e-commerce website, users navigate through the product taxonomy by clicking on the appropriate links that represent a hierarchical taxonomy.

Products may be categorized in a taxonomy according to their product attributes pursuant to an automated process. Alternatively, merchants may manually select one or more categories of the taxonomy for a product listing.

Increasingly, e-commerce website operators allow third parties, often referred to as “partners” or “product sellers,” to list products on their websites. Often times, the third party sellers desire to list their products on multiple e-commerce websites.

One difficulty facing product sellers that list products on multiple e-commerce websites is that each e-commerce website may have its own unique taxonomy and product attribute fields, sometimes referred to herein as a “schema.” That is, for each e-commerce website, sellers typically manually enter product attributes and product taxonomy information because this information is not easily transferable between different e-commerce websites due to the unique schema, i.e., taxonomy and product attribute fields, of each of the websites.

It would be an improvement of the art to provide an automated process that allows product sellers to list products on different e-commerce websites having unique schemas without having to manually enter information. It would be a further improvement to provide a system and method for automatic mapping between difference schemas.

The features and advantages of the present disclosure will be set forth in the description that follows, will be apparent from the description, or may be learned by the practice of the present disclosure without undue experimentation. The features and advantages of the present disclosure may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

According to an exemplary embodiment of the present invention, the program 24 can include a set of instructions that when executed by the processor 22, causes the server 21, to perform the operations of: providing an e-commerce website, including product information regarding products for sale. The product information may be displayed to users on the remote computers 27 on webpages, as viewed, for example, on a display 26 of one or more remote user computers 27, through the communication network 30, e.g., Internet.

To assist users in finding products listed for sale by the e-commerce server 21, product listings on the e-commerce server 21 may be organized pursuant to a unique schema, which includes product attributes and taxonomy information. The product attributes may be utilized to respond to search results conducted by users. Product attributes may be utilized to categorize products in the unique taxonomy. Alternatively, the products may be manually categorized in the taxonomy. Further, products may be categorized in search results based on their product attributes.

It will be appreciated by those having ordinary skill that the product attributes may include any information associated with the products, including, without limitation, general product descriptions, product type, brand, style, fashion, specific product descriptions, variants, condition, pricing and availability, unique product identifiers, gender, age group, color, size, material, pattern, title, etc.

Referring now to FIG. 2, a product seller 50 may desire to provide product listings on multiple e-commerce websites, shown as e-commerce websites 1 through N. Each e-commerce website may have its own schema for organizing product information, shown as schemas 1 through N. Each schema may have its own taxonomy structure and product attribute fields. That is, the taxonomies and product attributes across the e-commerce websites, 1 through N, may be unique. For example, a product categorization in the taxonomy of schema 1 may not be present in the taxonomy of schema 2. Likewise, product attributes dictated by schema 1 may not be present in the product attributes of schema 2. This is true because each schema may be unique to its own website as determined by the website operators.

Referring now to FIG. 3, there is depicted a mapping server 100 for automatically mapping taxonomy and product attributes between different schemas used by e-commerce websites. In particular, the product seller 50 may define product listings according to a source schema of an e-commerce website A. That is, the e-commerce website A requires that the product seller 50 provide taxonomy and product attribute information unique to the source schema. In an illustrative embodiment, the taxonomy and product attribute information for the products is entered manually through a computer in accordance with schema 1. In an illustrative embodiment, the taxonomy and product attribute information entered is for at least one product listing. In an illustrative embodiment, the taxonomy and product attribute information are for at least one hundred product listings. The taxonomy and product attribute information for the products entered pursuant to source schema is stored in a product database on an electronic storage medium.

At a future time, the product seller 50 may also desire to provide product listings on the e-commerce website B. In lieu of having the product seller 50 manually re-enter the product information according to a target schema, the mapping server 100 automatically maps the product information provided under the source schema to the target schema in the manner that will be described below. The taxonomy and product attribute information for the products entered pursuant to the target schema is stored in a product database on an electronic storage medium.

The mapping server 100 includes a processor 102 and a memory 104. The server 100 further includes a mapping program 106 stored on a tangible computer medium, such as, for example, one or more various types of memory, such as, for example, memory 104. The program 106 contains instructions, that when executed by the processor 102, causes the processor 102 to automatically map product taxonomy and attribute information from the source schema to the target schema. The server 100 can also include a plurality of database servers (not shown) that warehouse data regarding e-commerce conducted through the server 100. The server 100 may include a database of master attributes for the product listings as will be described in more detail herein after.

As understood by those skilled in the art, the memory 104 of the server 100 can include volatile and nonvolatile memory known to those skilled in the art including, for example, RAM, ROM, and magnetic or optical disks, just to name a few. It should also be understood by those skilled in the art that although illustrated as a single server, the illustrated configuration of the server 100 is given by way of example and that other types of servers or computers configured according to various other methodologies known to those skilled in the art can be used.

The server 100 shown schematically in, for example, FIG. 3 may represent a server or server cluster or server farm and is not limited to any individual physical server.

The server site may be deployed as a server farm or server cluster managed by a server-hosting provider. The number of servers and their architecture and configuration may be increased based on usage, demand and capacity requirements for the system.

Similarly, database servers (not shown) may connected to the server 100, each database server representing a server or server cluster or server farm and are not limited to any individual physical server or configuration.

As further understood by those skilled in the art, the program 106 can be in the form of microcode, programs, routines, and symbolic languages that provide a specific set or sets of ordered operations that control the functioning of the hardware and direct its operation, as known and understood by those skilled in the art. The program 106, according to an embodiment of the present invention, also need not reside in its entirety in volatile memory, but can be selectively loaded, as necessary, according to various methodologies as known and understood by those skilled in the art. As further understood by those skilled in the art, the term “computer-readable medium” encompasses distribution media, intermediate storage media, execution memory of a computer, and any other medium or device capable of storing the program 106 implementing the functionality or processes of various embodiments of the present invention for later reading by a computer.

When the program 106, or portions thereof, is to be run, it can be loaded either from its distribution medium or its intermediate storage medium into the execution memory of the server 100, configuring the server 100 to act in accordance with the functionality or method of various embodiments of this invention. All such operations are well known to those skilled in the art of computer systems.

According to an exemplary embodiment of the present invention, the program 106 can include a set of instructions that when executed by the processor 102, causes the server 100, to perform the operations of mapping the product taxonomy and attribute information organized pursuant to a source schema to the organization of a target schema. It will be appreciated that the program 106 eliminates the need for the product seller 50 to manually enter the information pursuant to the target schema. It will be further appreciated that a product's categorization pursuant to a given taxonomy may be considered a product attribute for purposes of this disclosure. It will be further appreciated, that the information exchanged between the mapping server 100 and the e-commerce websites A and B may be transmitted over a network, such as the Internet.

Referring now to FIGS. 3 and 4, there are depicted flow diagrams of a general overview of the algorithm of the mapping program 106 for mapping between different schemas. As shown, the program 106 causes the processor 102 to first reverse map at least one of the product attributes and taxonomy information defined in the source schema to populate a master attribute table. The master attribute table may be stored in a database.

The reverse map may be unique to the source schema. The reverse map may be stored in a database. Using the master attribute table, the program 106 then causes the processor 102 to map the entries in the master attribute table to the target schema. The mapping from the master attribute table to target schema may be unique. It will be appreciated that once created, that the master attributes may be utilized to map to multiple schemas. But, it will be appreciated that each mapping to a target schema is unique.

Referring now to FIG. 5, there are shown multiple examples, Examples A-G, of mappings from a source schema to a target schema by the server 100 using a reverse mapping and an assignment mapping. Each of these examples will be explained below.

Example A

This example demonstrates that a single product attribute in the source schema may be reverse mapped to multiple master attributes in the master attribute table. This example further demonstrates that multiple master attributes may be mapped to a taxonomy categorization in the target schema. This example further demonstrates that a single master attribute may be mapped to a product attribute in the target schema.

Example B

This example demonstrates that multiple product attributes in the source schema may be reversed mapped to determine a single master attribute. This example further demonstrates that a single master attribute may be mapped to determine multiple product attributes and a taxonomy categorization in the target schema.

Example C

This example demonstrates that a taxonomy categorization in the source schema may be reverse mapped to a master attribute. This example further demonstrates that a master attribute may be mapped to a product attribute in the target schema.

Example D

This example demonstrates that multiple master attributes may be mapped to a single taxonomy categorization in the target schema.

Example E

This example demonstrates that a product attribute in the source schema may be reverse mapped to a master attribute that is then mapped to multiple product attributes in the target schema as well as a taxonomy categorization.

Example F

This specific example demonstrates that a product attribute in the source schema may be reversed mapped to a master attribute in the master attributes table, and a different product attribute in the target schema.

Example G

This example demonstrates a specific example of how a taxonomy categorization in the source schema is mapped to a taxonomy categorization in the target schema. In this example, the target schema may not have a category for wedding rings in its taxonomy, but may have a taxonomy categorization for female gifts.

From the above examples, it will be appreciated that there is not necessarily a one-to-one correspondence between the source schema, master attributes, and the target schema. As used herein, the term “schema” may refer to the underlying organizational structure of the taxonomy and product attributes for organization of product information on an e-commerce website. It will be appreciated that the taxonomy categorization and the product attributes in the source and target schemas may be stored as name/value pairs in a database. It will be further appreciated that the master attributes may be stored as name/value pairs in a database.

Referring now to FIG. 6, in an illustrative embodiment, the product seller 50 may directly enter product attributes into the master attribute table 52 such that no reverse mapping is required. The master attributes in the master attribute table may then be mapped to the schemas of different e-commerce websites, e-commerce websites 1-N, using unique assignment mappings 1-N.

Referring now to FIG. 7, there is depicted a flow diagram of a computer-implemented process 200 for mapping at least one of product attributes and taxonomy information from a source schema to a target schema according to an illustrative embodiment of the present disclosure. The process 200 may be performed by the processor 102 of the mapping server 100 shown in FIG. 3. That is, the process 200 may be embodied in the mapping program 106 that is executed by the processor 102. At step 202, a master table is defined as an organizational structure in a computer database. The master table may include a column of master attributes and master taxonomies. Associated with each of the master attributes and master taxonomies are fields for data entry. At step 204, a computer-assisted reverse mapping from a source schema to the master table is defined. At step 206, a first assignment mapping from the master table to a first target schema and a second assignment mapping to a second target schema are defined. At step 208, at least one of product attributes and taxonomy information defined in the source schema is reverse mapped using the reverse mapping to populate fields in the master table. At step 210, the product information in the fields of the master table is mapped to the first target schema using the first assignment mapping and, optionally, the product information in the fields of the master table is mapped to the second target schema using the second assignment mapping. It will be appreciated that additional assignment mappings may be defined to map the information in the master table to additional target schemas.
