JP5299624B2 - Product search device and operation method of product search device - Google Patents

Description

  The present invention relates to a technique for a user to efficiently search for a product in shopping via the Internet.

  Currently, a so-called “net shopping” service is provided that allows a client PC to access a virtual store on the net and purchase a desired product. In addition, in such a service, a virtual shopping street called a “shopping mall site” that allows a plurality of types of merchandise to be purchased by integrating a plurality of virtual stores is constructed, The ones that have been provided are the mainstream. In these services, using the fact that product information is stored as a database in the server, a search keyword for specifying a desired product is input on the web page of the shopping mall site, and the desired product is obtained from the search result. Can also be easily found.

  In addition, the product information database has been devised so that hierarchical category information can be stored in association with product information so that a desired product can be easily found by a method for narrowing down categories other than the product search method using the above keywords. Yes. Specifically, for example, categories for each product such as “fashion”, “food”, “home appliance”, and “music” are displayed on the top page of the shopping mall site. If “Music” is clicked, the first category such as “J-POP”, “Western music”, “Classic”, “Anime”, “Indie”, etc. is displayed. Then, when the user clicks on the desired category such as “Western music”, the lower page of the Western music category “Pops”, “Rock”, “HR / HM”, “Hip-Hop”, etc. is displayed on the next page. Narrow down the category further. Then, product information associated with the narrowed categories is displayed in a list, and the user can search for a desired product. Patent Document 1 discloses a so-called recommendation in which a similar image search is performed based on a product image selected by the user, and a product hit by the search is presented to the user, thereby presenting a product that the user does not expect to the user. Technology is disclosed.

JP 2002-007803 A

  However, the conventional technique does not provide the above-mentioned “search by keyword” and “search by narrowing down the category” well integrated on the interface. Therefore, for example, after searching by keyword, searching for another product with reference to the same category as the product presented as a search result, such as seamless continuous search and mutual complementary search that link both search methods There is a problem that it is difficult to remove.

  Specifically, for example, when the user knows only the performer name “N orchestra” in a piecewise manner with respect to the desired product, the user searches for “N orchestra” as a keyword and listens to the audition data from the search results. Etc. to find the desired song “Cantata”. However, since all the performance songs of “N orchestra” are shown in the search result page, for example, the songs that “N orchestra” performed with the music belonging to the same genre “baroque music” as the desired music (cantata). It is difficult to continue searching from the search result page by the keyword.

  Also in the technique of Patent Document 1, if the product shape (album jacket for CD) is similar, the product will be presented to the user, and therefore a product in a completely different category may be presented. is there.

  In order to solve the above-described problems, the present invention provides a dynamically generated link for category search for “product attribute (category)” to which the product belongs when displaying a list of product IDs extracted by a search keyword. A product search device having a function of displaying in accordance with a list is provided. In this way, product extraction by category and keyword can be performed by clicking the product attribute on the search result page of keyword search. Therefore, seamless continuous search that links keyword search and category narrowing and mutually complementary Search can be performed.

  Specifically, a holding unit that holds a plurality of product IDs grouped by product attributes having a hierarchical structure, and an extraction unit that extracts product IDs belonging to the group having the product attribute according to the designation of the product attributes, A search unit for performing a product search with a search keyword to extract a product ID, an acquisition unit having first acquisition means for acquiring at least a part of the product ID extracted by the search unit, and the acquired product ID The product search apparatus includes a result display unit that displays a search result together with a button that designates a group of product attributes in any hierarchy to which the item belongs as a search range and executes a search with at least the same keyword.

  In addition, the product search device further includes a second acquisition unit in which the acquisition unit acquires at least a part of the product ID extracted by the extraction unit. In addition, the product search device includes a direct hierarchy display unit in which the result display unit displays only the product attribute of the hierarchy to which the product directly belongs from the group of product attributes to which the product belongs. Further, a search population designating means for designating a group of product attributes of any hierarchy to which the product ID extracted based on the search keyword in the search unit belongs as the search population to be executed by the keyword A product search device having In addition, a product search apparatus having a plurality of system display means for displaying two or more systems when the result display unit has two or more systems of product attributes having a hierarchical structure to which the product ID belongs is provided. Moreover, the operation | movement method of such a goods search apparatus is also provided.

  According to the present invention configured as described above, “search by keyword” and “search by narrowing down categories” can be successfully combined and provided on the interface in online shopping. Specifically, for example, after a search using the keyword “N orchestra”, the user designates a product ID group of “baroque”, one of the categories to which the product “cantata” as a search result belongs, as a search range. Then, it is possible to perform a re-search for narrowing down the products using the same keyword “N orchestra” as a search key and the group of the specified category as a search range, that is, re-search for baroque music performed by the N orchestra. . In this way, the user can easily perform a seamless continuous search in which both search methods are linked or a mutually complementary search.

FIG. 1 is a diagram illustrating an example of a display screen of a product search result by the product search device according to the present embodiment. As shown in this figure, for example, a user who accessed a shopping mall site on the Internet performed a product search using “N Orchestra” as a search keyword. Then, “N orchestra” is a performer as a search result, and CD products “Cantata”, “Diva” and the like including the information as search tag information are displayed in a list with thumbnails.

  In the product search apparatus according to the present embodiment, hierarchical product category information (grouping based on product attributes) such as “Classic> Baroque Music> Bach” and “Classic> Operatta> Offenbach” that can be clicked on the product hit in the search. Information) α and β are also displayed together. In this way, the user, for example, clicks “baroque music” from the search result page, and continuously selects CD products of baroque music performed by the N orchestra that are further narrowed down by category in addition to the search keyword. Or you can search complementarily.

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the commodity search apparatus according to the present embodiment. Note that the functional blocks of the product search device described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications.

  Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or the hard disk is processed and stored, An instruction for controlling the software is generated. In addition, the present invention can be realized not only as a product search apparatus but also as a method. A part of the invention can be configured as software. Furthermore, a software product used for causing a computer to execute such software and a recording medium in which the product is fixed to a recording medium are naturally included in the technical scope of the present invention (the same applies throughout the present specification). Is).

  As shown in FIG. 2, the “product search device” (0200) of the present embodiment includes a “holding unit” (0201), an “extraction unit” (0202), and a “search unit” (0203). , “Acquisition unit” (0204) having “first acquisition means” (0205), and “Result display unit” (0206).

  The “holding unit” (0201) has a function of holding a plurality of product IDs grouped by product attributes having a hierarchical structure, and can be realized by, for example, an HDD, a nonvolatile memory, a recording medium, and a reading drive thereof. it can. In addition, “product attribute having a hierarchical structure” means that, for example, as shown in FIG. 3, the first attribute is “music”, and the lower second attribute is “Japanese music”, “Western music”, “classic”, etc. The genre of music handled in the shop is associated. Furthermore, subordinate to the second attribute, each genre is further subdivided, and third attributes such as “POP” and “Rock” for Japanese music, “Baroque” and “contemporary music” for classical music are associated. That's it. For example, if the music is Bach, it can be grouped by “product attributes having a hierarchical structure” such as “(music)> classical> baroque music> Bach”.

  “Product ID” refers to information for identifying a product, such as a product name or a product number. Note that the product name may not indicate a version difference, for example, and does not strictly identify the product strictly. However, in the present invention, the product ID is presented to the user as a product search result. The identification information is good if the product can be distinguished. Therefore, the product ID is a concept including the product name.

  FIG. 4 is a diagram illustrating an example of holding product IDs grouped by such “product attributes having a hierarchical structure”. As shown in this figure, for example, the product identified by the ID “B001” and the product name “JS Bach“ Cantata ”” has the first layer “Classic” and the second layer “Baroque Music” (also Although it is not shown in the drawing, it is grouped according to product attributes having a hierarchical structure in which the third hierarchy is “Bach”). In addition, the product ID is associated with search tag information to be used for a search by a search keyword, for example, “N orchestra (player)”.

  Then, for example, by storing the information shown in this figure as a database and holding it in the holding unit, it is possible to perform a search by keyword or a product search by narrowing down product attributes (categories).

  The “product attribute” used for grouping the product ID is not limited to the genre as in the above example, and may indicate various attributes related to the product. For example, if the product is valuable for the brand, it may be configured to include “Manufacturer / Brand Type” in the hierarchical product attribute, or a numerical range such as “Product Weight” or “Product Price”. It may be an attribute.

  In addition, the holding unit holds the product ID and the product attribute having the hierarchical structure or the search tag information in association with each other as described above. Further, as shown in FIG. Product information such as text data and price information for product explanation (not shown) and URL of a Web shop site where the product can be purchased may be stored in association with each other. In this way, when the product ID is displayed on the result display section described later, these product information can also be displayed together.

  The “extractor” (0202) has a function of extracting a product ID belonging to a group having the product attribute in accordance with specification of the product attribute, and can be realized by, for example, a CPU, a main memory, an extraction program, or the like. . Specifically, for example, product attribute names, icons indicating the product attributes, and the like are displayed side by side on a Web page such as a shopping mall site. When the user designates a desired product attribute with the input device, the product ID associated with the product attribute is extracted with reference to a database as shown in FIG.

  Further, it is preferable that the product attribute group belonging to the hierarchical lower level of the product attribute designated by the user is continuously displayed on the Web page so that the user can narrow down the product attribute.

  The “search unit” (0203) has a function for executing a product search using a search keyword and extracting a product ID, and can be realized by, for example, a CPU, a main memory, an extraction program, or the like. Specifically, for example, a search window is provided on a web page such as a shopping mall site. Then, when the user inputs a desired search keyword in the search window using the input device, this also refers to the database as shown in FIG. 4 to determine whether the keyword matches the product name or search tag information not shown. The matching product ID is extracted.

  In the product search device according to the present embodiment, after the “product ID extraction process based on the search keyword” in the search unit, the “product ID extraction process based on product attributes” in the continuous or complementary extraction unit can be easily performed. Can be executed. And in order to provide the user interface which can operate the said continuous or complementary goods ID extraction process easily, the goods search apparatus of a present Example is characterized by further having the following structures.

  The “acquisition unit” (0204) includes first acquisition means. The “first acquisition unit” (0205) has a function of acquiring at least a part of the product ID extracted by the search unit, and is realized by, for example, an acquisition program including a CPU, a main memory, and a first acquisition program. Can do.

  “Result display section” (0206) is a function for designating a group of product attributes of any hierarchy to which the acquired product ID belongs as a search range and displaying a search result together with a button for executing a search with at least the same keyword. For example, it can be realized by a CPU, a main memory, a result display program, or the like. Hereinafter, a specific example of display in the result display unit will be described with reference to FIG.

  FIG. 5 is a diagram illustrating an example of a Web page displayed by the function of the result display unit. As shown in FIG. 5A, for example, a Web page that displays a list of product IDs (product names) “cantata” of products corresponding to the search keyword “N orchestra” acquired by the acquisition unit is generated. Then, for example, the product attribute “classic> baroque music> Bach” to which the search result product “cantata” belongs is acquired from the database as shown in FIG. 4 and displayed in the vicinity of the product ID on the Web page so as to be clickable. , And so on. In this way, the user can specify the search range by an operation such as clicking on the product attribute of any hierarchy to which the product ID displayed in the search result list belongs.

  Then, the user operates the input device to place the cursor α on “baroque music” in the hierarchical product attributes and click. Then, as shown in FIG. 5B, this time, the product ID belonging to the designated product attribute “baroque music” is extracted by the processing of the extraction unit. Then, using the extracted product ID group as a search range, the product ID extraction process by the search unit is executed again with the keyword “N orchestra”. Then, for example, “Pachelbel's Canon and Zieg” and “Handel's Symphony” are acquired as baroque music performed by the N orchestra and displayed as a result list.

  The “button” displayed in the search result display screen includes a clickable character string as described above, and must be a three-dimensional image or icon simulating a real button. There is no.

  In addition to the product ID such as the product name, the result list displayed on the result display unit refers to the database held in the holding unit as described above, and the product image, product description, price Alternatively, the URL of a Web shop site where the product can be purchased may be displayed together.

  As described above, the product search apparatus according to the present embodiment performs a search for another product using the same keyword A with a search range as a group of any hierarchy to which the product as a search result belongs after the search using the keyword A in the search unit. It is possible to provide a user interface that can be easily performed.

<Hardware configuration>
FIG. 6 is a schematic diagram illustrating an example of a configuration in the commodity search apparatus when the functional components are realized as hardware. The operation of each hardware component in the search result page display process will be described with reference to FIG.

  As shown in this figure, the product search device is a “CPU (central processing unit)” (0601) for executing arithmetic processing related to the extraction unit, search unit, acquisition unit, and result display unit and other various arithmetic processing. ) And “main memory” (0602). In addition, a “HDD” (0603) serving as a holding unit and a “communication circuit” (0604) for information communication with the user client PC1 or PC2 are also provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “HDD”, and in the arithmetic processing of the “CPU”, the address is specified and the stored data is accessed to access the data. It is possible to perform the arithmetic processing used.

  Here, access to the shopping mall site is executed from the PC 1 or PC 2 of the user connected through the network, and the HTTP request is received by the “communication circuit” of the product search apparatus. Then, the merchandise retrieval apparatus returns HTML data of the shopping mall site held in “HDD” to the user's PC as an HTTP response.

  Then, the web page of the accessed shopping mall site is displayed on the user's PC by the reply from the product search device. Then, the user inputs a keyword for searching for a desired product such as “N Orchestra” in the search window column provided on the page, and clicks the search button. Then, an HTTP request including the input search keyword is transmitted from the user's PC and received by the “communication circuit” of the product search device.

  In the product search device, the received search keyword is stored at address 1 of “main memory”. Further, in response to the search command indicated by the HTTP request, the search program is read into the “main memory”, and the “CPU” interprets the search program. Then, according to the interpretation result, among the items in the product database (DB) held in “HDD” as shown in FIG. 4, those that match the search keyword stored in “main memory” Whether or not there is is determined by logical operation processing of “CPU”.

  Then, a product ID having an item that matches the search keyword is extracted and stored in the address 2 of the “main memory”. Subsequently, for each extracted product ID, a hierarchical product attribute associated with the product ID is acquired from the product DB, and stored in addresses 3... Of “main memory”.

  Then, the “CPU” interprets the first acquisition program included in the acquisition program, and identifies, for example, the top 10 product IDs (for example, the number of items that can be displayed on one Web page). Subsequently, “CPU” interprets the result display program. Then, in accordance with the interpretation, HTML data of a search result page in which the identified top 10 product IDs are listed is generated and stored as result display data 1 at address 4 of “main memory”. Also, the HTML data is characterized in that the product attribute information stored at the address 3 of the “main memory” is embedded as a dynamically generated link that can be specified by clicking, for example.

  Then, the HTML data is returned as an HTTP response from the “communication circuit” to the user's PC via the network. Then, a result display page 1 as shown in FIG. 5A is displayed on the user's PC. Here, when the user wants to search for a CD of another composer of the same genre (product attribute) as Bach, for example, a link display part such as a product attribute “baroque music” on the result display page 1 is clicked. Then, an HTTP request including the clicked product attribute is then transmitted from the user's PC and received by the “communication circuit” of the product search device.

  Then, the merchandise retrieval apparatus stores the merchandise attribute included in the received HTTP request at the address 5 of the “main memory”, similarly to the reception of the search keyword. Further, in response to the extraction command indicated by the HTTP request, the extraction program is read into the “main memory”, and the “CPU” interprets the search program. Then, in accordance with the interpretation result, the product attribute item of the product database (DB) held in “HDD” as shown in FIG. 4 is searched and associated with the product attribute by logical operation processing of “CPU”. The product ID being extracted is extracted.

  Then, for example, the top 10 product IDs are identified from the extracted product IDs, the HTML data of the category extraction result page listing the identified product IDs is generated, and the result display data 2 is “ Stored at address 6 of "main memory". Then, the HTML data is returned as an HTTP response from the “communication circuit” to the user's PC via the network. Then, the result display page 2 in which the product ID is extracted by the product attribute as shown in FIG. 5B is displayed on the user's PC.

<Process flow>
FIG. 7 is a flowchart illustrating an example of a processing flow in the commodity search apparatus according to the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care.

  As shown in this figure, first, for example, a search keyword input by a client PC connected via a network is received (step S0701). Then, a product search is executed by referring to the product database with the received search keyword, and a product ID including the search keyword is extracted (step S0702). Then, at least a part of the extracted product ID, for example, 10 items that can be displayed in one page of the web page is acquired (step S0703).

  Subsequently, a group of product attributes to which the product identified by the acquired product ID belongs is specified with reference to, for example, a product database. Then, the product attribute specified in association with the product ID is displayed on the client PC so as to be designated (step S0704). Therefore, on the client PC, when an operation for specifying one of the hierarchical product attributes is accepted (step S0705), the product ID belonging to the group having the specified product attribute is assigned to the product database or the like. Refer to and extract (step S0706). Then, using the extracted product ID as a search range, the product ID extraction process using the search keyword accepted in step S0701 is executed (step S0707), and the further refined search results are listed and displayed on the display. It is.

<Brief description of effect>
As described above, after the search using the keyword A by the product search apparatus of the present embodiment, the product ID group included in one of the categories to which the product of the search result belongs is specified as the search range, and the same keyword A is set as the search key. Thus, it is possible to provide a user interface capable of easily executing a refinement and re-search for different products. Therefore, the user can easily perform a seamless continuous search and a mutually complementary search in which both search methods are linked.

Example 3
<Overview>
FIG. 10 is a diagram for explaining an example of display of product search results and the like by the product search device of the present embodiment. As shown in this figure, there is a product “cantata” grouped by hierarchical product attributes such as “...> Baroque music> Bach”. Here, in the present embodiment, when displaying the product ID searched with the search keyword “N orchestra” as a search result, not all the hierarchical product attributes are displayed together, but the hierarchical product ID is displayed. For example, as shown in FIG. 10B, only a part of the product attributes, that is, “Bach” positioned one level above the cantata is displayed α. In this way, the user designates only the product attribute one level above the product. Therefore, when a user searches for another product by narrowing down the hierarchical product attributes, the product attributes are narrowed down from the next higher level, rather than narrowing down by product attributes that cover an unnecessarily wide range. It is possible to go on. Further, even when the hierarchical structure is increased, it is not necessary to increase the display space for the product attributes, so that the display screen can be used effectively.
