Description

Method and electronic device for generating extended URL

The present invention relates to the field of network technology, and in particular to a method for generating an extended URL.

Optical Character Recognition (OCR) is a technology for identifying text in images. In current mobile phone systems, there are many applications with OCR, such as Line, Google Lens, etc. These applications can interpret the text in the picture, and when the address bar is detected, they will automatically mark the hyperlink. Provided to users for selection. However, if the URL in the image is defective, the current OCR function will only identify the characters that appear, and then give wrong links, causing users to be unable to find the web page. If the above-mentioned website has special processing for wrong URLs, it will usually be directed to the homepage of the above-mentioned website. However, whether the webpage cannot be found or the method of redirecting to the homepage will prevent users from connecting to the webpage they originally wanted to open. What's more, if the above URL is composed of hash codes or is of considerable length, it may be difficult for users to search and the above web page will no longer be found. Therefore, the present invention proposes a method that can expand the above-mentioned web address according to the detected web address, thereby filling in the missing web address.

Embodiments of the present invention relate to a method for generating an extended URL. The above method includes: using a processor to use optical character recognition (OCR) technology to identify at least one character string and the original URL from the image. The original URL includes the path information of the current level and the path information of the upper level above the current level. The path information of the upper level corresponds to the directory and the directory web page. The above method further includes the processor using the character string recognized in the image or at least one link recorded in the directory web page to generate at least one extended URL related to the original URL.

In some embodiments, the method further includes determining whether the path information of the current level exceeds a predetermined number of words. In response to judging that the path information of the current level exceeds the predetermined number of characters, it is judged whether the first n characters of the string match the path information of the current level, where n is the number of characters of the path information of the current level. In response to the fact that the first n characters of the string match the path information of the current level, the first n characters of the string are removed and connected to the path information of the current level of the original URL to generate at least one candidate URL of the extended URL. .

In some embodiments, the above method further includes determining whether the HTTP status code of the web page corresponding to the candidate URL is 200 OK. In response to the Http status code being 200 OK, the processor uses the candidate URL with the Http status code as 200 OK as the extension URL.

In some embodiments, the above method further includes determining whether the HTTP status code of the directory web page is 200 OK. In response to the HTTP status code of the directory page being 200 OK, the processor uses the link recorded in the directory page to generate the extended URL. In some embodiments, the URLs corresponding to all links recorded in the directory web page are used as candidate URLs for the expanded URL. In some embodiments, the processor treats the candidate URL containing the original URL as the expanded URL.

In some embodiments, the method further includes displaying the expanded URL on a screen. In some embodiments, the path information of the current level is the part after the last slash character of the original URL.

Embodiments of the invention relate to an electronic device. The above-mentioned electronic device includes: processor, memory, and network interface. Memory contains one or more machine-readable instructions that are read and executed by the processor. A network interface connects electronic devices to the Internet. When the machine-readable instructions are read and executed by the processor, the processor is caused to run the method for generating an extended URL according to the embodiment of the present invention.

For example, the memory 104 stores image data, multimedia files (such as music or video files), wireless connection information (such as information that allows the electronic device 100 to establish a wireless connection, such as a network connection), and any other suitable information.

The memory 104 may include non-volatile memory, such as read only memory (ROM), flash memory (flash memory), hard disk, optical computer readable media, magnetic computer readable media , solid-state computer readable media, and combinations thereof. The memory 104 may also include volatile memory, such as dynamic random access memory and static random access memory.

For example, the screen 110 can be controlled by the processor 102 to display a specific image. For example, the screen 110 can be a liquid crystal panel, a touch screen, etc., but is not limited to this.

The processor 102 is coupled to the memory 104, the network interface 106, the camera 108 and the screen 110, and can control the above components or exchange information with the above components. The processor 102 is connected to the Internet through the network interface 106 to connect with the remote server. The processor 102 sends the request to the remote server through the network interface 106 and receives the response message from the remote server. The processor 102 executes the machine-readable instructions 105 in the memory 104 to execute the method of generating an extended URL of the present invention. The method of generating an extended URL of the present invention will be described in detail below.

Figure 2 is a flow chart of an embodiment of the present invention, schematically illustrating a method 200 for generating an extended URL. Method 200 may be performed by processor 102 executing machine-readable instructions 105 in memory 104 . In operation 202, processor 102 receives a picture. The processor 102 may receive pictures (or image files) from the camera 108 , or the processor 102 may read pictures (or image files) stored in the memory 104 .

In operation 204, the processor 102 uses OCR technology to identify a plurality of word strings from the image, and identifies a website address from the plurality of word strings. For example, the processor 102 may first separate the background part of the picture from the text part (which may include text, numbers and punctuation marks). The processor 102 then separates all the characters, numbers and punctuation marks in the separated text parts into separate character images. The processor 102 then captures the characteristics of each character image, compares the captured characteristics with the text in the text database, and determines which text, number or symbol the character image should be. After using the OCR technology to identify multiple characters, numbers or symbols from the image, the processor 102 outputs the multiple characters, numbers or symbols recognized from the image and stores them in the memory 104 . The processor 102 can recombine the recognized characters, numbers or symbols into a word string that appears on the picture and store it. In the embodiment of the present invention, a character refers to a single text, number or symbol, and a string is composed of multiple characters. In some embodiments, the processor 102 executes an application with optical character recognition (OCR) function, such as Line, Google Lens, etc., in order to interpret the text in the picture.

The processor 102 then identifies at least one string as a uniform resource locator (URL) from the plurality of strings. For example, the processor 102 can determine whether the first few characters of the string are "http://", "www" or "http:// www." and whether the last few characters are "http://", "www" or "http://www." Specific strings such as ".com" and ".gov". In addition, the processor 102 can also determine whether the string contains characters such as dot (".") or slash ("/"). If the conditions are met, the processor 102 determines that the string is a URL (hereinafter, the recognized URL will be referred to as the original URL), associates the message that the string is a URL with the string, and stores it in the memory 104 . The original URL recognized by the processor 102 may be a URL that enables the processor 102 to successfully connect to a web page, or may be a URL that cannot enable the processor 102 to connect to any web page.

The original URL recognized by the processor 102 may include multiple path information, and each path information is separated by a slash character. In addition, the root directory URL and/or at least one subdirectory URL of the original URL can be constructed based on the path information in the original URL. Each path information-level subdirectory has an upper-lower relationship. For example, the original URL identified by the processor 102 may have directory path information such as a root directory path, a first-level sub-path, a second-level sub-path, and a current path. The part after the last slash character of the original URL (the first slash character from the right) can be called the current path (that is, the path information of the current level). The part between the second to last slash character (the second slash character from the right) and the last slash character of the original URL can be called an N-level sub-path (here, N-level sub-path represents the upper part of the current path). one level path). The part between the third to last and the second to last of the original URL can be called the N-1 level sub-path, and so on. The part from "http://" to the first slash character can be called the root directory path. The root directory path is the root directory URL of the original URL. By appending the upper-level sub-path with slash characters after the root directory path, you can get the first-level sub-directory URL of the original URL. By connecting the upper-level sub-path and the second-level sub-path with slash characters after the root directory path, you can get the second-level sub-directory URL of the original URL. By analogy, by connecting the upper-level sub-path to N-level sub-paths in sequence with slash characters after the root directory path, the N-level sub-directory URL of the original URL can be obtained. The original URL can be obtained by connecting the upper-level sub-path to the current path with slash characters after the root directory path. Each path information can correspond to a subdirectory URL or a root directory URL, and each subdirectory URL and root directory URL can correspond to a web page and/or directory. The root directory path, first-level sub-paths to N-level sub-paths can all be called upper-level path information of the current path (that is, upper-level path information). The root directory URL, the first-level subdirectory URL to the N-level subdirectory URL can all be called the upper-level URL of the original URL.

In other words, by removing the part after the last slash character of the original URL, you can get the current subdirectory URL of the original URL. By removing the part after the second slash character from the original URL, the N-level subdirectory URL of the original URL can be obtained. By removing the part after the third slash character from the original URL, you can get the N-1 subdirectory URL of the original URL, and so on. For example, when the original URL is https://www.acer.com/ac/zh/TW/content/ces-awarded-products, the root directory path is https://www.acer.com/. The first-level subpath is ac, the second-level subpath is zh, the third-level subpath is TW, the fourth-level subpath is content, and the current path is ces-awarded-products. The root directory path is the root directory URL. In addition, the first-level subdirectory URL can be obtained as https://www.acer.com/ac/ as mentioned above. The second-level subdirectory URL is https://www.acer.com/ac/zh/. The third-level subdirectory URL is https://www.acer.com/ac/zh/TW/. The fourth-level subdirectory URL is https://www.acer.com/ac/zh/TW/content/.

In operation 206, the processor 102 uses the string stored in the memory 104 and the original URL to generate an expanded URL of the original URL. In some embodiments of the invention, the extended URL is a URL that includes the original URL. The processor 102 may compare the first few characters of the string with the last few characters of the current path, that is, compare the first few characters of the string with the last few characters of the original URL. When the first few characters of the string are the same as the last few characters of the current path, the last few characters of the original URL are replaced with the above string to form an expanded URL of the original URL. Alternatively, the processor 102 can connect to the Internet 107 through the network interface 106 to access the web page corresponding to the upper path of the current path of the original web address, that is, to access the web page corresponding to the subdirectory web address or the root directory web address. The processor 102 then obtains the link recorded in the web page. Finally, the processor 102 uses the above-linked URL as the extended URL of the original URL. The processor 102 stores the generated extended URL into the memory 104, and the processor 102 controls the screen 110 to display the extended URL.

Optionally, operation 206 may be performed after the processor 102 determines that the original URL is an invalid URL. For example, the processor 102 can connect to the Internet 107 through the network interface 106, try to connect to the web page corresponding to the original URL, and receive the server response of the above web page through the Internet 107 and the network interface 106. HyperText Transfer Protocol (Http) status code (Http Status Code). Http status code is a code used to indicate the response status of the web server's Hypertext Transfer Protocol, expressed as a 3-digit number. It can be divided into five categories according to the number at the beginning, namely reference information starting with 1 (1XX), success (successful) starting with 2 (2XX), redirection starting with 3 (3XX), and redirection starting with 4 ( 4XX) client error (client error), starting with 5 (5XX) server error (server error). The HTTP status code 200 OK represents that the client request was successful. The processor 102 determines whether the received HTTP status code is 200 OK. If it is not 200 OK, the processor 102 determines that the original URL is an invalid URL, and performs operation 206. If it is 200 OK, the processor 102 determines that the original URL is a valid URL and does not perform operation 206.

Referring to Figure 3, Figure 3 is a flow chart of an embodiment of the present invention, schematically illustrating a method 300 of generating an extended URL using word strings in images. Method 300 may be performed by processor 102 executing machine-readable instructions 105 in memory 104 . In operation 302, the user activates the OCR function on a picture (or image file), causing the processor 102 to receive or read the picture. The picture may be captured by the camera 108 and then sent to the processor 102 and/or the memory 104 , or the picture may be a picture previously stored in the memory 104 and read by the processor 102 . In operation 304, the processor 102 uses the OCR technology to identify a plurality of word strings from the image as described above, and identifies the original URL from the word strings. The processor 102 stores the recognized character string and the original URL into the memory 104 . The processor 102 then displays and provides a hyperlink corresponding to the original URL on the screen 110 for the user to click. For example, the processor 102 may provide a hyperlink that can be linked to the website corresponding to the original URL. Or, when the user clicks on the hyperlink, the processor 102 attempts to connect to the original URL through the network interface 106 .

In operation 306, the processor 102 determines whether the number of characters of the current path of the original URL (that is, the path information of the current level) exceeds a predetermined number of characters. That is to say, the processor 102 determines whether the last slash character of the original URL is (That is, the first slash character from the right of the URL) Whether the number of characters after it exceeds the predetermined number of characters. The predetermined number of words can be 2, 3, 4, 5, or more than 5. If operation 306 is not performed, or the predetermined number of characters is set too small, the subsequent expanded URL found will be inaccurate. If the processor 102 determines that the number of characters after the last slash character of the original URL does not exceed the predetermined number of characters, the processor 102 performs operation 318. In operation 318, the processor 102 only displays the original URL on the screen 110 for the user's reference. If the processor 102 determines that the number of characters in the current path of the original URL exceeds the predetermined number of characters, the processor 102 performs operation 308.

In operation 308, the processor 102 searches for the word string previously recognized from the image in operation 304. In some embodiments, processor 102 reads each string previously stored in memory 104 in operation 304 . In operation 310, the processor 102 compares the read string with the original URL. In some embodiments, the processor 102 first determines how many characters the current path of the original URL has. Here, we take the current path of the original URL as having 5 characters as an example. Next, the processor 102 compares the first 5 characters of each string to see if it matches the current path of the original URL. A matching string can be the exact same string as the current path of the original URL, or a matching string can be a string that only differs from the current path of the URL in English upper and lower case. The only difference in English case is that the letters in the string and the current path of the URL are the same, except that one is uppercase and the other is lowercase. For example, "abc", "Abc", and "AbC" all differ only in English upper and lower case, so they will be judged as matching strings by the processor 102. When the processor 102 finds strings whose first five characters match the current path of the URL, the processor 102 can mark these strings to indicate that these strings are matching strings.

In operation 312, the processor 102 generates candidate URLs for extending the URL using the matching strings. In some embodiments, the processor 102 removes the current path (last 5 characters) of the original URL to become the upper URL. Afterwards, the processor 102 connects the matching strings to the upper-level URL, and generates candidate URLs for the extended URL. In other words, the processor 102 replaces the current path of the URL with a matched string to generate a candidate URL for extending the URL. In addition, in some embodiments, the processor 102 may also first remove the first 5 characters of the matching string, and then connect the remaining parts to the original URL to generate a candidate URL for the extended URL. When the only difference between the matching string and the current path of the URL is English uppercase or lowercase, the processor 102 may first convert all the matching strings into English uppercase or English lowercase, and then replace the current path of the original URL with the matching string. Path, or remove the first 5 characters of the converted string and connect it to the end of the original URL. When there are multiple matching strings, the processor 102 will generate multiple candidate URLs for the extended URL, and may record these candidate URLs in the form of a list and store them in the memory 104 .

In operation 314, the processor 102 performs a connection test on all candidate URLs, and removes the candidate URLs that fail the connection test from the list. The processor 102 can connect to the Internet 107 through the network interface 106, try to connect to the candidate website, and receive the HTTP status code responded by the remote server. When the received HTTP status code is not 200 OK, the processor 102 removes the candidate URL from the list. This ensures that all subsequent extension URLs provided to users can be connected. In operation 316, the processor 102 displays the candidate URLs in the list as expanded URLs on the screen 110. In some embodiments, the processor 102 can display the original URL and the expanded URL simultaneously.

Referring to Figure 4, Figure 4 is a picture 400 of an example of an embodiment of the present invention. The following uses the picture 400 as an example to illustrate each operation of the method 300. In operation 302, the user uses the OCR function on the picture 400. In operation 304, the processor 102 identifies a plurality of word strings from the picture 400, including word strings 401, 402, 403, and 404, and the processor 102 determines that the word string 404 is an original website address (also referred to as the original website address 404 ), providing the user with the 404 hyperlink of the original URL. In operation 306, the processor 102 determines whether the current path of the original URL 404 exceeds a predetermined number of characters, which is 3 in this example. The original URL 404 recognized by the processor 102 is: https://www.acer.com/ac/zh/TW/content/ces-aw, and the part after the last slash character of the original URL 404 (the current path) is "ces-aw", because "ces-aw" exceeds 3 characters, processor 102 continues to perform operation 308.

In operation 308, the processor 102 reads a plurality of word strings including the word strings 401, 402, and 403. In operation 310 , the processor 102 compares the read string with the original URL 404 . Here, the strings 401, 402, and 403 are used as examples. Since there are 6 characters after the last slash character of the original URL 404 (that is, the first slash character from the right of the URL), the processor 102 will determine the first 6 characters at the beginning of the strings 401, 402, and 403. Whether the element is the same as "ces-aw". The content of string 401 is "Ces-Awarded-Products". Since the first six characters of string 401, "Ces-Aw" and "ces-aw", are only different in upper and lower case, the processor 102 determines that string 401 is consistent. string. The content of string 402 is "Aspire". Since the first six characters of string 402, "Aspire", are different from "ces-aw", the processor 102 determines that string 402 is not a matching string. The content of string 403 is "immersive". Since the first six characters "immers" of string 403 are different from "ces-aw", the processor 102 determines that string 403 is not a matching string. Assume that the processor 102 recognizes the string "ces-awsome" from the image 400. Since the first six characters of the string "ces-awsome", "ces-aw" and "ces-aw" are the same, the processor 102 determines the string "ces-awsome" is a matching string.

In operation 310 , the processor 102 generates candidate URLs for the extended URL of the original URL 404 using the strings 401 previously determined to match. The processor 102 can remove the first 6 characters of the string 401 to become "arded-Products". The processor 102 then appends "arded-Products" to the original URL 404 to generate the candidate URL https://www.acer.com/ac/zh/TW/content/ces-awarded-Products. In some embodiments, the processor 102 may also convert all the string 401 into lowercase to become "ces-awarded-products". The processor 102 then appends "arded-products" to the original URL 404 to generate the candidate URL https://www.acer.com/ac/zh/TW/content/ces-awarded-products. In addition, assuming that the processor 102 recognizes the string "ces-awsome" from the image 400, the processor 102 can also use the string "ces-awsome" to generate the candidate URL https://www.acer in the above manner. com/ac/zh/TW/content/ces-awsome.

In operation 312, the processor 102 attempts to connect to the candidate URL found in operation 310 through the network interface 106, and determines whether the received HTTP status code is 200 OK. Assume that only the HTTP status code of the candidate URL https://www.acer.com/ac/zh/TW/content/ces-awarded-products is 200 OK, and the HTTP status code of other candidate URLs is 404 not found. The processor 102 removes other candidate URLs whose HTTP status code is not 200 OK from the list. In operation 316, the processor 102 displays both the original URL 404 and the extended URL https://www.acer.com/ac/zh/TW/content/ces-awarded-products on the screen 110.

Referring to Figure 5, Figure 5 is a flow chart of an embodiment of the present invention, schematically illustrating a method 500 for generating an extended URL using the upper path of the original URL. Method 500 may be performed by processor 102 executing machine-readable instructions 105 in memory 104 . Operation 502 of method 500 is the same as operation 302 of method 300. Operation 504 of method 500 is the same as operation 304 of method 300. Operation 518 of method 500 is the same as operation 316 of method 300, which will not be described again here.

In operation 506, the processor 102 goes to the upper level directory of the currently searched directory (web page). When no search has been performed, the processor 102 goes to the web page corresponding to the upper-level path of the current path of the original website address (that is, the upper-level path information). The processor 102 can find the last slash character followed by a character in the URL corresponding to the currently searched web page (the currently searched URL), and remove the part after the slash character to generate a directory of the upper layer. URL. Alternatively, the processor 102 can use slash characters to determine all sub-paths and root directory path information of the original URL based on the original URL, and construct all levels of sub-directory URLs and root directory URLs as described above. When it is necessary to go to the upper level directory of the currently searched directory, the upper level URL can be found from the currently searched URL, and the processor 102 connects to the web page corresponding to the upper level URL through the network interface 106 .

In operation 508, the processor 102 determines whether the HTTP status code received after connecting to the web page corresponding to the upper-layer URL is 200 OK. If the received HTTP status code is not 200 OK, processor 102 performs operation 512. If the received HTTP status code is 200 OK, the processor 102 performs operation 510.

In operation 510, the processor 102 searches for the web page corresponding to the upper level URL and records all the links recorded in the web page. For example, the processor 102 can search for the html tag (tag) in the hypertext markup language (html) of the web page and find all hypertext reference (href) attributes in the tag. The href attribute can specify the URL of the hyperlink target. The value of the href attribute can be a relative or absolute URL of any valid document, including fragment identifiers and JavaScript code snippets. The link is recorded in the href attribute, and the processor 102 records the URL corresponding to the link recorded in the href attribute as a candidate URL for the extended URL, and stores the candidate URL for the expanded URL in the memory 104 . Alternatively, when the website address is recorded in the href attribute, the processor 102 may directly store the website address into the memory 104 as a candidate website address for the extended website address.

In operation 512, the processor 102 determines whether the currently searched URL is the root directory URL of the original URL. If the currently searched URL is not the root directory URL of the original URL, the processor 102 performs operation 506 again. If the currently searched URL is the root directory URL of the original URL, the processor 102 performs operation 514. The way to determine whether it is a root directory URL may be that the processor 102 makes a determination based on the slash characters in the currently searched URL. For example, when the currently searched URL contains only 1 except for the slash characters in "http://". When there are three slash characters (or when there are only three slash characters in total), the processor 102 determines that the currently searched URL is the root directory URL of the original URL. Alternatively, the processor 102 may directly compare the currently searched URL with the root URL previously generated based on the original URL. When the two are the same, the processor 102 determines that the currently searched URL is the root URL of the original URL.

In operation 514, the processor 102 compares the candidate URL stored in the memory 104 with the original URL to determine whether the comparison results match. The processor 102 may first determine whether the candidate URL is exactly the same as the part before the last slash character of the original URL, that is, whether the candidate URL is identical to the original URL except for the current path. After determining that the candidate URL and the original URL are identical except for the current path, the processor 102 may determine whether the first M characters of the current path part of the candidate URL and the original URL are the same. M is, for example, 3, 4, 5, 10, or any predetermined suitable number. If they are the same, the processor 102 determines that the candidate URL is consistent with the original URL. Alternatively, the processor 102 may determine whether the candidate URL contains the original URL. The processor 102 may determine whether the first N characters of the candidate URL are the same as the original URL, where N is the number of characters of the original URL. In addition, the processor 102 may also try to connect to the candidate website and determine whether the received HTTP status code is 200 OK. In operation 516 , the processor adds the candidate URLs with matching results to the list, and stores the list in the memory 104 .

Method 500 is to record the links in the web pages corresponding to the subdirectory URLs at each level of the original URL and the root directory URL. This approach is to selectively record links without recording all links that can be directly or indirectly connected to the web page corresponding to the root directory URL. This saves search time and makes it easier to find the expanded URL that's related to the original URL.

Referring to Figure 6, Figure 6 is a picture 600 of an example of an embodiment of the present invention. The following uses the picture 600 as an example to describe each operation of the method 500. In operation 502, the user uses the OCR function on the image 600. In operation 504, the processor 102 identifies multiple character strings from the picture 500, including the character string 601, and the processor 102 determines that the character string 601 is an original URL (also called the original URL 601), and converts the original URL 601 hyperlinks are provided to users. In operation 506, the processor 102 goes to the web page corresponding to the upper level URL of the original URL 601. The content of the original URL 601 is https://www.cdc.gov.tw/Disease/SubIndex/WYbKe3aE7LiY5gb. The processor 102 can remove part of the current path of the original URL 601, that is, remove "WYbKe3aE7LiY5gb" to generate the previous layer. The subdirectory URL https://www.cdc.gov.tw/Disease/SubIndex/, and go to the web page corresponding to the previous subdirectory URL. In operation 508, the processor 102 determines whether the HTTP status code received from the web page corresponding to the upper-level subdirectory URL is 200 OK. When the received HTTP status code is 200 OK, the processor 102 records the link recorded in the web page corresponding to https://www.cdc.gov.tw/Disease/SubIndex/ in operation 510, and performs operation 512. In operation 512, since https://www.cdc.gov.tw/Disease/SubIndex/ contains multiple slash characters in addition to the slash character in "http://", the processor 102 determines that the current search The URL is not the root URL of the original URL 601 and action 506 is performed. In operation 506, the processor 102 finds the last slash character of the currently searched URL https://www.cdc.gov.tw/Disease/SubIndex/ followed by a string, and converts the part after the slash character Remove the copy, generate the upper-level subdirectory URL https://www.cdc.gov.tw/Disease/, and go to its corresponding web page. Repeat operations 506 to 512 until the web page corresponding to the root directory URL https://www.cdc.gov.tw/ of the original URL 601 has been searched.

Alternatively, in operation 506, the processor 102 may first determine the sub-paths at each level and the root directory path of the original website address 601, which are respectively the current path WYbKe3aE7LiY5gb, the second-level sub-path SubIndex, the first-level sub-path Disease, and the root directory path https: //www.cdc.gov.tw. And construct the subdirectory URLs of each layer and the root directory URL of the original URL 601 as mentioned above, which are the second-level subdirectory URL https://www.cdc.gov.tw/Disease/SubIndex/ and the first-level subdirectory URL https: //www.cdc.gov.tw/Disease/, and the root directory URL https://www.cdc.gov.tw. The processor 102 then repeatedly performs operations 506 to 512 to search all sub-directory URLs and web pages corresponding to the root directory URL layer by layer, and in operation 512, the currently searched URL can be directly compared with the root directory URL.

In operation 514, when one of the recorded candidate URLs is https://www.cdc.gov.tw/Disease/SubIndex/WYbKe3aE7LiY5gb1, since the first 55 characters of the candidate URL are the same as the original URL 601, that is The candidate URL contains the original URL 601. The processor 102 determines that the comparison result between the candidate URL and the original URL 601 is consistent. Similarly, the processor 102 will also determine the candidate URL https://www.cdc.gov.tw/Disease/SubIndex/WYbKe3aE7LiY5gb12 and the candidate URL https://www.cdc.gov.tw/Disease/SubIndex/WYbKe3aE7LiY5gb-aa Matches the original URL 601. In operation 516 , the processor 102 adds the candidate URLs determined to be consistent with the original URL 601 to the list, and in operation 518 displays the URLs in the list as extended URLs of the original URL 601 on the screen 110 .

Referring to Figure 7, Figure 7 is a flow chart of an embodiment of the present invention, schematically illustrating a method 700 of generating an extended URL using the string in the image and/or the upper path of the original URL. Method 700 may be performed by processor 102 executing machine-readable instructions 105 in memory 104 . Operation 702 of method 700 is the same as operation 302 of method 300 and operation 502 of method 500. Operation 704 of method 700 is the same as operation 304 of method 300 and operation 504 of method 500. Operations 706-714 of method 700 are the same as operations 306-314 of method 300. Operations 716 to 726 of method 700 are the same as operations 506 to 516 of method 500, and will not be described again. When it is determined in operation 706 that the number of characters in the last paragraph of the original URL exceeds the predetermined number of characters, the processor 102 performs operations 706 to 714. Otherwise, the processor 102 does not perform operations 706 to 714, and the processor 102 only performs operations 716 to 714. 726 to find out the extension URL.

In operation 728, the list may include the expanded URL generated by using the string in the image in operations 706~714, and the expanded URL generated by using the upper path of the original URL in operations 716~726. The processor 102 may first remove duplicate URLs from the list, and then display the URLs in the list as expanded URLs of the original URLs on the screen 110 . If in step 706 the processor 102 determines that the number of characters in the current path of the original URL does not exceed the predetermined number of characters, operations 708 to 714 will not be executed at this time, so only the upper layer of the original URL is used in operations 716 to 726 in the list. The expanded URL generated by the path.
