  The product information acquisition system of the present invention is a system for acquiring information related to a product designated by a user via the communication network 400 in the user terminal 100 of the user. A plurality of information providing sites 300 disclosed in the above are used as product information acquisition sources. The management server 200 performs management so that the user terminal 100 can automatically determine an appropriate information providing site 300 and acquire the product information.

  Here, “product” refers to a product such as a part used for electrical work, in which a product number is assigned to each item for distinction.

  For example, in addition to parts such as electrical work and electronic work, products with such product numbers are products sold in catalogs such as mail order, various electrical products such as TVs and PCs, There are various industrial products such as automobiles and motorcycles, and these can be handled as “products” for acquiring related information in the product information acquisition system of the present invention.

  Referring to the network configuration of the present embodiment in FIG. 4, user terminals 100-1,..., 100-n of each user, which is a terminal from which the user acquires product information, via the communication network 400. The information providing sites 300-1,..., 300-m, which are websites of individual business operators that disclose information related to products, are connected. Furthermore, a management server 200 is also connected, and performs management so that each user terminal 100 can appropriately and automatically select these information providing sites 300 from which information is acquired.

  The management server 200 registers and manages address correspondence information indicating the correspondence between the product number assigned to each product and the address of the web page related to the product for each information providing site 300. Then, the user terminal 100 accesses the management server 200 via the communication network 400 to acquire the address correspondence information, and automatically refers to the address correspondence information to the web page related to the product of the product number designated. Real access.

  The communication network 400 is a network such as the Internet for performing information communication. In addition to the Internet, a personal network using a personal computer communication, an in-house LAN, data communication via a telephone line, and other dedicated lines may be used.

  The user terminal 100 is a terminal used by a user for information acquisition, and has a communication function via the communication network 400. For example, a personal computer, a mobile phone, a mobile terminal, etc. can be used.

  The management server 200 is a server that allows each user terminal 100 to automatically select the information providing site 300 appropriately and acquire information. The management server 200 is provided with address correspondence information necessary for the management, and communicates the information. Each user terminal 100 is made to acquire via the network 400. The management server 200 can use a commercially available server device or a computer having other server functions.

  Each of the information providing sites 300-1,..., 300-m is a website that provides information via the communication network 400, and is a target for acquiring product information by the user terminal 100. Each information providing site 300 can be, for example, a site that publishes information on products handled by each business operator on a web page.

  Further, although the operator of the product information acquisition system of the present invention manages the management server 200, it is not necessary to operate or manage each information providing site 300, and it is operated by another organization. It may be managed. The business of each information providing site 300 may be a site that is managed and operated by an individual business.

  Referring to FIG. 1, a user terminal 100 according to the present embodiment is a terminal having a function of communicating via a communication network 400, and includes a browser 110, an address correspondence information storage unit 120, an address correspondence information acquisition unit 130, and a product number. A designation unit 140, an address search unit 150, and an information acquisition unit 160 are provided.

  The browser 110 is a browser for connecting to each information providing site 300 via the communication network 400 and displaying a web page of product information.

  The address correspondence information storage unit 120 is a storage unit for storing address correspondence information acquired from the management server 200.

  The address correspondence information acquisition unit 130 communicates with the management server 200 to acquire the latest address correspondence information in each information providing site 300 and store it in the address correspondence information storage unit 120.

  The acquisition processing of the latest address correspondence information may be executed only when it is confirmed that the address correspondence information has been updated by inquiring the management server 200 whether the address correspondence information has been updated.

  Inquiry to the management server 200 about whether the address correspondence information is updated can be automatically made by the user terminal 100 based on a predetermined schedule. For example, an inquiry may be made when the user terminal 100 is activated, or an inquiry may be made periodically once a day.

  The product number specifying unit 140 accepts a user's specifying operation for specifying a product for which information is to be acquired. In the product designation operation, designation is performed using the product number.

  The address search unit 150 searches for the address correspondence information in the address correspondence information storage unit 120 acquired from the management server 200 using the product number received by the product number designation unit 140, thereby obtaining information on the product of the product number. Get the address of the web page that offers

  The information acquisition unit 160 acquires information on the product by connecting the browser 110 to the web page of the address obtained by the address search unit 150 and displaying the web page.

  As described above, the web page indicating the product information designated by the user is displayed on the browser 110 of the user terminal 100.

  Here, the product number is a model number of a product used for indicating the product on an information providing site that provides information on the product. In many cases, a short character string such as “A123”, “HK-567”, “05555”, and “PP0123” is used.

  In the product number specifying unit 140, there are various methods for the user to specify the product number. For example, a method of inputting a character string of the product number directly from the keyboard, a product number (or product) A list of products (including product number information) that is displayed on the display and selected from the list, or a product number that is displayed on the building material parts that make up each part of the building in a CAD drawing such as construction A method of performing a selection operation by placing a mouse cursor, a method of designating a character string stored in the clipboard of the OS of the user terminal 100 as a product number, and the like are conceivable.

  Referring to FIG. 2, the management server 200 of this embodiment includes an address correspondence information storage unit 210, a license information storage unit 220, an industry classification information storage unit 230, and an address correspondence information update unit 240.

  The address correspondence information storage unit 210 registers address correspondence information 211 indicating the correspondence between the product number assigned to the product and the address of the web page related to the product for each information providing site 300.

  In the example of FIG. 2, in the address correspondence information storage unit 210, the address correspondence information 211-A, 211-B,... Is remembered.

  The address correspondence information 211 is acquired on the user terminal 100 side by the address correspondence information acquisition unit 130 of the user terminal 100 via the communication network 400.

  Further, in the license information storage unit 220 and the industry classification information storage unit 230, the setting of the types of these address correspondence information 211 acquired by the user terminal 100 from the management server 200 is recorded. As a result, the user terminal 100 can correctly acquire the address correspondence information 211 required by the user.

  The license information storage unit 220 records license information registered for each individual user as to whether or not to obtain the address correspondence information 211 for each information providing site 300. As a result, the address correspondence information acquisition unit 130 of the user terminal 100 executes the acquisition process only on the address correspondence information 211 permitted to be acquired by the user based on the setting of the license information for the user. .

  The industry classification information storage unit 230 records industry classification information obtained by classifying the information providing site 300 for each industry. For example, it is classified into “electric work”, “pipe work”, “water service work”, etc., based on the field of products handled by the information providing site 300.

  Here, in the license information of the license information storage unit 220, whether or not to obtain address correspondence information for each user can be set using the type of business to which the information providing site 300 belongs.

  In other words, it is very troublesome to specify the license information indicating whether or not it is possible to acquire for each information providing site 300, but it is very troublesome, but it is summarized according to industries such as “electric work” and “pipe work”. This makes it possible to easily set the necessary information providing site 300.

  FIG. 5 is a diagram showing an example of license information 221 of a method designated by the type of business according to the first embodiment, and FIG. 6 is a diagram showing an example of the business category classification information 231 according to the first embodiment.

  Thus, for example, in the case of a user who is permitted to acquire the type of “electric work” in the license information (Mr. Ichiro Suzuki in the example of FIG. 5), the user terminal 100 address correspondence is based on this license information. The information acquisition unit 130 of the information providing site 300 (electrical material component manufacturer A, electric material trading company site B... In the example of FIG. 6) classified as “electrical work” in the industry classification information storage unit 230 of the management server 200. The acquisition process is executed only for the address correspondence information 211.

  The address correspondence information update unit 240 analyzes the web page related to the product published on each information providing site 300, automatically checks whether the information is updated, and provides information if it is updated. By automatically generating information on the correspondence between the product number assigned to each product currently disclosed on the site and the address of the web page related to the product based on the analysis result of the web page, The address correspondence information is automatically updated to the latest information.

  The update processing for each information providing site 300 by the address correspondence information updating unit 240 is automatically executed periodically according to the update frequency of each information providing site 300.

  As a result, the latest correct address correspondence information can always be provided to the user terminal 100 automatically.

  Referring to FIG. 3, the information providing site 300 of this embodiment includes a product information storage unit 310 that records a web page of product information. Moreover, although not necessarily required, the search part 320 for searching the web page in each information provision site 300 is provided.

  Thus, for the information providing site 300 having the function of the search unit 320 for searching the web page in the server, even when the product number designated by the user does not correspond to the search in the address correspondence information 211. The information acquisition unit 160 uses the product number to search for these information providing sites 300, so that the product information can be automatically acquired even in such a case.

  Next, a method for recording data of the address correspondence information 211 will be described.

  In each information providing site 300, since the character string of the address of the web page of each product is almost the same, by devising the data recording method, the number of bytes required for the address correspondence information 211 can be reduced. It can be greatly reduced.

For example, in an information providing site 300, the address of each product “S001” “T002” “UOO3”.
http://Company.co.jp/001.html
http://Company.co.jp/002T.html
http://Company.co.jp/003.html
...
In this case, only the “001”, “002T”, and “003” portions of the address are extracted and recorded as shown in the address correspondence information 211-1 in the example of FIG. This is sufficient, and the address search unit of the user terminal 100 can easily restore these to the original correct addresses and use them.

  As described above, in the address correspondence information 211 in each information providing site 300, a character string of a part that is sufficient to uniquely distinguish the address from the character string of the address in the information providing site 300 that discloses the address. The product of the product number is recorded based on the extraction method of the extracted address in the information providing site 300 from the extracted address corresponding to the search by the address search unit 150 of the user terminal 100, which is recorded using the extracted extracted address. A method of restoring the character string of the address of the web page that provides the information can be adopted.

  Thereby, the data capacity required for the address correspondence information 211 can be significantly reduced to a fraction or less, and the address correspondence information 211 is acquired from the management server 200 to the user terminal 100 via the communication network 400. It is easier to do this, and the storage capacity required in the user terminal 100 can be reduced.

  In addition, the extraction method of the extracted address and the restoration method from the extracted address to the original address conform to the address rules for each individual information providing site 300, and are the same on the user terminal 100 side and the management server 200 side. It is necessary to adopt a method.

  For this purpose, for example, a method for restoring from the extracted address in the user terminal 100 to the original address (that is, information on the character string added before and after the extracted address in order to restore the original address) is performed on the management server 200 side. Prepare and store the address correspondence information 211 simultaneously with the address correspondence information 211, store it in the terminal, and refer to it at the time of restoration. It can be restored.

  Also, a method for recording data of the address correspondence information 211 and a method for efficiently avoiding erroneous input errors when a character string of a product number is designated by character input will be described.

  This is a method used after converting the character string of the product number used for the search into a character string in which a portion that is likely to cause an erroneous input is deleted and a portion indicating main information is left.

  When entering the product number by entering characters, there is a high possibility that the character string of the regular product number is different from uppercase and lowercase letters, or a character string that is different from full-width and half-width is entered incorrectly. If there is a difference, make sure that it matches the search, and if the product number contains symbols such as spaces, minus “-” or parentheses, drop these symbols to remove the product number. In the same way, if there is such a difference, it is required to be applied to the search.

  For example, when inputting the product number “B-4000”, if various inputs such as “b-4000”, “b-4000”, “B4000”, “B4000”, etc. are entered, all are correct. It is preferable to make it correspond to a search.

  For this reason, in the address correspondence information 211, the search product number in which all the characters of the character string of the product number are capitalized and characters other than numerals and letters are deleted is recorded, and the user terminal 100 The address search unit 150 searches for the address correspondence information 211 after making the character string of the product number designated by the user in the same manner, making all the characters uppercase and deleting characters other than numbers and letters. Adopt the method.

For example, in an information providing site 300, the address of each product “B-3000” “B-4000” “B-5000”.
http://B.co.jp/search?ID=B-3000
http://B.co.jp/search?ID=B-4000
http://B.co.jp/search?ID=B-5000
...
In this case, “B3000”, “B4000”, “B5000”,... Are recorded as address correspondence information 211-2 in FIG.

  As a result, when the product number “B-4000” is input by characters, even if various inputs such as “b-4000”, “b-4000”, “B4000”, “B 4000”, etc. are entered, The address search unit 150 of the user terminal 100 converts all the characters to uppercase letters, deletes characters other than numbers and letters, and searches for the address correspondence information 211-2 after converting them to “B4000”. Thus, the address of the product number “B-4000” can be acquired correctly.

  By performing the search after converting to the search product number in this way, it is extremely unlikely that the search does not match the search due to a character input error.

  In the prior art, a method of performing a fuzzy search by absorbing the difference between full-width and half-width and the difference between uppercase and lowercase in the search by a character string has been implemented, but in this embodiment, other than numbers and letters It is characterized by searching after removing characters.

  This method has a great effect in obtaining a correct search result in the search for the character string of the product number.

  In the example of the address correspondence information 211-1 and 211-2 in FIGS. 7 and 8, for the purpose of displaying the data in the figure, the product number and address of each product are in a comma-separated format. Although it is displayed, it is not limited to the comma-delimited CSV text file format.

  Even when various other formats that are easy to access by the program are adopted for the address correspondence information 211, the data capacity can be greatly reduced by recording the data by the above-described extraction address and search product number method. And avoiding input mistakes are realized in the same way.

  FIG. 9 is a flowchart illustrating the product information acquisition process of the user terminal 100 according to the present embodiment.

  Referring to FIG. 9, as described above, the operation of acquiring the product information by the user terminal 100 according to the present embodiment is as follows. First, the product (product number) for which the user acquires information by the product number specifying unit 140. Is designated (step 1001).

  Then, the address search unit 150 searches each address correspondence information stored in the address correspondence information storage unit 120 using the product number, and acquires the address where the product information is disclosed (step 1002). .

  Subsequently, the information acquisition unit 160 connects the browser 110 to the address (step 1003), and a web page indicating the product information designated by the user is displayed on the browser 110 of the user terminal 100. (Step 1004), the acquisition of information is completed.

  FIG. 9 and FIG. 10 are flowcharts for explaining processing for obtaining and updating the latest address correspondence information from the management server 200 in the user terminal 100 according to the present embodiment, and processing on the user terminal 100 side and the management server 200 side, respectively. Is shown.

  Referring to FIGS. 10 and 11, as described above, the operation of acquiring and updating the latest address correspondence information from the management server 200 in the user terminal 100 according to the present embodiment is performed first by address correspondence of the user terminal 100. The information acquisition unit 130 inquires of the management server 200 whether there is an update in the address correspondence information used by the user (steps 1101 and 1201).

  Then, the management server 200 refers to the license information of the user recorded in the license information storage unit 220 and confirms which information providing site 300 is permitted (step 1202).

  Further, for example, in the case of the method of indicating the information providing site 300 permitted by the type of business as described above in the license information of the user, when the business type of “electric work” is permitted, the management server 200 Further, with reference to the industry classification information storage unit 230, the information providing site 300 classified as the industry of “electric work” is acquired.

  Then, among the information providing sites 300 permitted to the user, there is one whose address correspondence information is updated, and if there is one, which information providing site 300 is it? (Step 1203), and responds to the user terminal 100 (step 1204).

  If there is no update, the user terminal 100 ends this update process. If there is an update, the user terminal 100 requests the management server 200 for the address correspondence information of the updated information providing site 300. Download and update the address correspondence information of the updated information providing site 300 in the address correspondence information storage unit 120 (step 1102).

  Next, as a method for recording data in the address correspondence information 211, a search process (see FIG. 9) of the address search unit 150 of the user terminal 100 when the extracted address or the search product number is used as described above. Step 1002) will be described in detail.

  FIG. 12 is a flowchart for explaining the search process of the address search unit 150 of the user terminal 100 for each address correspondence information 211 recorded by adopting the extracted address and the search product number.

  Referring to FIG. 12, the search processing (step 1002 in FIG. 9) of the address search unit 150 of the user terminal 100 when the extraction address and the search product number are adopted is first passed by the product number specifying unit 140. The product number is converted into a search product number in which all characters of the character string are converted to uppercase letters and characters other than numerals and letters are deleted (step 1002-1).

  And what matches the search product number is searched from each address correspondence information 211 using the search product number, and the corresponding address is acquired (step 1002-2).

  Since the acquired address is an extracted address, a restoration rule from the extracted address to the original address in each address correspondence information 211 corresponding to the search (for example, a predetermined character string is added before and after the extracted address). Based on the above, the original address is restored (step 1002-3).

  Thereby, since the address of the web page of the product with the passed product number has been acquired, this address is sent to the information acquisition unit 160 (step 1002-4), and the search process of the address search unit 150 is completed.

  Next, an example in which the address search unit 150 performs a search process (step 1002 in FIG. 9) will be described. This is to increase the possibility of matching with a search by executing a partial match search of a character string when it does not correspond to a complete match search, and sequentially execute partial match searches by two methods. It is characterized by that.

  FIG. 13 is a flowchart illustrating an example of a search process performed by the address search unit 150 of the user terminal 100 according to this embodiment.

  Referring to the example of FIG. 13, the address search unit 150 of the user terminal 100 firstly matches the product number designated by the user in the product number designating unit 140 with each address in the address correspondence information storage unit 210. A search is performed from the address correspondence information (step 1002-2-1).

  If there is no product number corresponding to this exact match search, a product number including all the character string of the product number designated by the user from the head is searched from each address correspondence information (step 1002-2-2). Here, for example, “ABC100” or “ABCXX” corresponds to the search for “ABC” input.

  If there is no product number corresponding to this partial match search, on the contrary, a search is made for items that are all included from the beginning in the character string of the product number designated by the user (step 1002-2). -3). Here, for example, “PPP5” or “PPP” corresponds to the search for the input of “PPP5555”.

  If any of the above-described searches is applicable, the corresponding address is acquired (step 1002-2-4). If none of the searches is applicable, the search fails and ends.

  In this way, by sequentially executing a partial match search for searching for a character string including one from the beginning, the possibility that any address corresponds to the search at the time of executing the search is greatly increased.

  This is because even if the search is a partial match search instead of an exact match search, the top part of the product number will match, so it is highly possible that the handling company matches, and the purpose is This is a useful method with a high possibility of being able to easily go to the product web page of the product number.

  In addition, in the conventional character string search processing system, in general, a product number that includes all of the character string of the product number designated by the user in step 1002-2-2 may be searched. The method of searching for product numbers that are all included in the character string of the product number designated by the user in step 1002-2-3, which is the reverse of this, from the beginning is not adopted.

  This is because in the normal case, there is no point in executing the search as in step 1002-2-3, but when searching for the product number as in the present invention, a very good effect is realized. It was.

  In the case of product numbers such as electrical parts, there is a method of adding character strings indicating various attributes (differences in wattage, dimensions, format, etc.) to the end of the product number one after another. This is because the search purpose is often achieved if a search is made that matches the part of the character string of the input product number even if there is no match to the end.

  For example, if you search the product catalog and enter a product number such as “ABC123 100W 800x100” and it does not match the search, if a search matches “ABC123 100W” or “ABC123” In the product web page, the product number starting with “ABC123 100W” or “ABC123” is often explained, or a list of all the products is listed. Can be expected.

  In addition, as is often the case with conventional character string search processing systems, in the method of searching for product numbers that are close to the dictionary order when they do not match the search, for example, “ABC123 10000” for “ABC123 100W 800x100” However, since this is a product number that includes a part that does not match the entered product number, there is a high possibility that the product number is different from the expected product. It is impossible to expect the effect of the preceding paragraph such that information about the originally intended product is described on the product web page.

  In this way, even if the item number that exactly matches the item number specified by the user or the item number that contains all the item numbers from the beginning is not registered, the character string of the item number specified by the user is reversed. By searching for everything contained from the top, it is possible to open a web page of a product that is expected to be related to the product intended by the user, thereby realizing high convenience.

  Next, when there is an information providing site 300 that includes a search unit 320 for searching a web page in the server as shown in the example of FIG. 3, this search function is used for acquiring product information of the present invention. The method will be described.

  FIG. 14 is a flowchart illustrating an address search process (step 1002 in FIG. 9) by the address search unit 150 of the user terminal 100 according to the present embodiment, which uses the web search function on the information providing site 300 side. .

  First, the address search unit 150 searches for address correspondence information (step 1002-3-1). If there is a match, the corresponding address is obtained and information is obtained in the same manner as in the flowchart of FIG. (Step 1002-3-2).

  Here, if there is no match, the product number located in the dictionary order before and after the searched product number is checked for the location of the information providing site 300 (step 1002-3-3). The reason why the site of the product number located before and after in the dictionary order is checked is that there is a high possibility that it is the information providing site 300 that provides information on the product designated by the user.

  Subsequently, it is checked whether or not there is a site having a product number positioned before and after in the dictionary order as a site having a search function (step 1002-3-4).

  In the case where the site of the product number located before and after this is a different site having a search function, either one of the addresses (for example, the one with the larger number of matching characters from the top of the product number) is searched Adopt as.

  If there is no site having a search function, the search has failed and the process is terminated (step 1002-3-5).

  If there is a site having a search function, a web page address for displaying a search result on the information providing site 300 based on the searched product number is generated and sent to the information acquisition unit 160. It is displayed on the browser 110 (step 1002-3-6).

  In step 1002-3-6, as a method of automatically generating a web page address for displaying a search result, such a search address is searched in most information providing sites 300 having a search function. Since it can be generated simply by adding a predetermined character string before and after the product number, the address of the search result is displayed for each information providing site 300 having a web search function in advance. By registering the generation method in the user terminal 100, an address can be automatically generated based on the registered method.

  For example, it can be automatically generated by a simple method of adding a character string of a predetermined address such as product number “C150” → address “http://c.com/product?num=C150”.

  Next, a specific example regarding the operation of designating the product number in the product number designating unit 140 in step 1001 of FIG. 9 will be described.

  In the present embodiment, description has been made mainly on the method of directly inputting the product number directly up to now, but here, an example of the method of designating that the product shown in the form data is selected will be described.

  In this case, the user terminal 100 includes a form data display unit 145 that displays form data as shown in FIG. FIG. 15 is a diagram illustrating an example of form data displayed by the form data display unit 145.

  The form data handled here is tabular data composed of cells arranged vertically and horizontally, indicating each product in each vertical row, and specifying the product in each row for each horizontal column In addition, a column indicating the product number of the product in each row is included as one of the horizontal columns.

  In the form data in the example of FIG. 15, individual products “Lighting with sensor function manufactured by Company A”, “Lighting for insect control made by Company B” and the like are described in each row. Various information (attributes) related to the purchase of the product are shown, and there are columns for displaying each information such as a product name column and a product number column 145-1.

  FIG. 16 is a flowchart for explaining a product selection operation (step 1001 in FIG. 7) by a user according to an example using the form data display unit 145.

  Referring to FIG. 16, when a user selects a product, first, when the form data display unit 145 displays the form data (step 1001-1), the user uses the mouse and the up and down keys of the keyboard. When a product row for which information is to be acquired is selected (step 1001-2), the product number of the product indicated in the product number column 145-1 of that row is obtained (step 1001-3). The number is acquired and the product selection operation is completed.

  In this way, even if you want to specify the product information shown in the form data, you can specify the product with a simple operation to select the product column and acquire the product information. Can do.

  As described above, according to the product information acquisition system of the present embodiment, the user can instantly display a web page for publishing information on the product with a simple operation without knowledge about the product.

  In addition, since the management server 200 is provided and a service can be provided to the user independently from the business operator of each information providing site 300, only the information providing site 300 of a specific business operator can acquire information. Rather than targeting, users can acquire information for sites across the industry for products for which users are seeking information.

  In addition, since the user terminal 100 can automatically acquire and update the latest address correspondence information from the management server 200, the user can always ask for it without being bothered by changes in the site configuration of the information providing site 300 or the like. Product information can be obtained.

  Also, the management server 200 can automatically provide the latest information automatically by checking the address correspondence information by automatically visiting the individual information providing sites 300, so that the management burden is not increased. That's it.

  Further, since the method for managing the address correspondence information for each information providing site 300 is minimized, it is easy to cope with the update of information in each information providing site 300, and the user terminal is individually provided for each information providing site 300. 100 becomes easy.

  Furthermore, since the address correspondence information is managed for each information providing site 300, it is not necessary to include a column indicating where the information providing site 300 is in the data of each address correspondence information (FIG. 7, 8), management is easy and the data size of each address correspondence information can be small.

  Even when the process of restoring the extracted address to the original address as described in the flowchart of FIG. 12 is adopted, the restoration method differs for each information providing site 300. Can be restored to their original addresses by a common restoration method, and the restoration process in the address search unit 150 can be efficiently executed.

  FIG. 17 is a block diagram illustrating a configuration of the user terminal 100a according to the second embodiment of the present invention.

  In the present embodiment, in addition to the configuration of the first embodiment, several types of functions are added.

  The priority order storage unit 125 records and sets priority setting information of the information providing site 300. As a result, the address search unit 150 refers to the priority order setting information, and when there are a plurality of products corresponding to the product number designated by the user, the high-priority information is provided based on the priority order. Information with priority given to the site 300 is acquired.

  This defines processing when a plurality of web pages correspond to the search at the time of the search.

  Each user has a manufacturer who often uses the product or a manufacturer who does not often use the product. Even if the product has the same type, name, and product number, the web page of the frequently used manufacturer can be displayed with priority. I was asked.

  Therefore, the setting of the priority order is recorded in the priority order storage unit 125, and information with priority given to the information providing site 300 having a higher priority order is acquired based on the priority order.

  As a specific method for acquiring information based on this priority order, when a plurality of information corresponds to the search at the same time, a list of information providing sites 300 corresponding to the search is displayed in order from the highest priority site, The method of requesting the user's operation to select a site for acquiring the information, or the web page of the information providing site 300 having the highest priority among the search results is displayed first, and at the same time, the priority order is higher than that corresponding to the search. For example, an interface for switching to another low site can be displayed on the screen of the user terminal 100a.

  FIG. 18 is a diagram showing an example of the priority order information 126 according to the present embodiment. For this user, priorities are set in the order of the electrical material component manufacturer A, the electrical material trading company site B, the electrical material component manufacturer C,. Has been.

  The address correspondence information generation unit 135 automatically obtains information on the correspondence between the product number assigned to each product currently disclosed to the information providing site 300 and the address of the web page related to the product, The address correspondence information of the information providing site 300 is automatically generated.

  This is to provide the user terminal 100a with the same function as the address correspondence information update unit 240 provided in the management server 200 in the first embodiment.

  This is suitable for acquiring information of the information providing site 300 that is frequently updated, and the address correspondence information is stored in the user terminal 100a without waiting for the address correspondence information to be updated on the management server 200 side. It becomes possible to update to the latest one and acquire information appropriately.

  The algorithm used by the address correspondence information generation unit 135 to automatically generate address correspondence information is a script that describes the conversion method for each information providing site 300 from the management server 200 via the communication network 400. A method of acquiring as a text file, a method of acquiring in a format such as a program module for executing the automatic generation, and the like are possible.

  The search index generation unit 170 generates a search index for executing an overall index search for a plurality of acquired address correspondence information. Accordingly, when the latest address correspondence information is acquired from the management server 200, the search index generation unit 170 newly generates and updates a search index stored in the user terminal 100. Further, the address search unit 150 refers to the address correspondence information stored in the user terminal 100 and the search index, thereby executing an overall index search for the plurality of acquired address correspondence information. .

  Further, based on the priority setting stored in the priority storage unit 125 described above, a search index may be generated so that the web page of the information providing site 300 having a high priority corresponds to the search first. .

  As described above, according to the product information acquisition system of the present embodiment, the priority storage unit 125 is provided so that the information providing site 300 having a high priority can be displayed with priority, and the address correspondence information generation unit 135 is displayed. The address correspondence information can be updated in response to the update of the information providing site 300 on the user terminal 100a side, and the index for searching in the user terminal 100a can be provided by providing the search index generation unit 170. Can be generated to perform an index search.
