Description

Technical Field

[0001] The present invention relates to the technical field of information updating, and in particular to a method and system for collecting enterprise information. Background Art

[0002] If you want to obtain a company's contact information and other corporate information, the general way is to directly visit the company's official website and extract the company's corporate information from the homepage of the company's official website. However, due to the different structures of different official websites, corporate information may not be directly displayed on the homepage. Extracting the company's contact information directly from the homepage of the company's official website can only obtain surface data, and cannot accurately locate the location of the required corporate information, which is prone to data loss. At the same time, the update time of each corporate official website is different. If the same information extraction cycle is used for all corporate official websites, it will cause a lot of waste of resources, and for those companies with high web page information update frequency, their corporate information cannot be extracted in time. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0026] Embodiment 1:

[0027] Figure 1 This is a flow chart of the method for collecting enterprise information provided in Example 1 of the present invention.

[0028] Reference Figure 1 , the collection methods of enterprise information include:

[0029] Step S101, obtaining the to-be-visited link of the enterprise official website according to the preset weight value of the information collection frequency.

[0030] Here, the link to be visited is stored in the first database. The first database stores more than one link to be visited.

[0031] In one embodiment, referring to Figure 2 , the preset weight value of the information collection frequency is determined by the following steps:

[0032] Step S201, obtaining the corporate official website link in a preset second database.

[0033] Here, the preset second database stores all the enterprise official website links that need to be accessed in advance. These enterprise official website links are the official websites of the enterprises whose enterprise information actually needs to be obtained.

[0034] Step S202: extract the target domain name information in the corporate official website link, and compare the target domain name information with the domain name information in the first database.

[0035] Here, the target domain name information refers to the information up to ".com" in the company's official website link. For example, http: / / www.xxyyzz.com / is a domain name information.

[0036] Step S203, if the target domain name information is different from the domain name information, the target domain name information is saved to the first database, the corporate official website link corresponding to the target domain name information is determined as the link to be visited, and the preset weight value of the information collection frequency corresponding to the link to be visited is determined as the initial weight value.

[0037] Here, when the target domain name information is different from the domain name information, it means that the enterprise official website link corresponding to the target domain name information has not been stored in the first database before, and the enterprise official website link is determined as a link to be accessed and saved in the first database. At this time, only the enterprise official website link is saved and the link is not accessed.

[0038] The preset weight value of the information collection frequency indicates the number of times the link to be visited is accessed. The initial weight value can be set according to the actual situation. In this embodiment, the initial weight value can be set to 4, which means that the link to be visited is accessed once every 4 weeks to update the enterprise information.

[0039] Step S102, determining whether the link to be accessed is the first access link.

[0040] In one embodiment, step S102 includes:

[0041] The enterprise information corresponding to the link to be accessed in the first database is obtained.

[0042] Here, the enterprise information includes enterprise contact information, web page snapshot files, and hash values ​​of the page bytecodes of the enterprise's official website.

[0043] If the enterprise information is empty, determine that the link to be accessed is the first access link.

[0044] Step S103: if the link to be visited is the first time to be visited, open the first display page corresponding to the link to be visited, and extract the target link corresponding to the preset keyword in the first display page by using the keyword recognition technology.

[0045] Here, the preset keyword can be preset according to actual conditions. In order to extract the enterprise contact information, the preset keyword can be set to "Contact Us". There is at least one preset keyword. The target link is a link containing the enterprise contact information.

[0046] Specifically, if the first display page corresponding to the link to be accessed contains "Contact Us", and the "Contact Us" corresponds to an A tag (hyperlink), the A tag corresponding to "Contact Us" is found through keyword recognition technology, and the link corresponding to the A tag is extracted as the target link. The target link is a link containing the company's contact information. At the same time, the link to be accessed is replaced with the target link and saved in the first database.

[0047] If "Contact Us" in the first display page is not a hyperlink, it means that the first display page includes the enterprise contact information, and the link to be visited is determined to be the target link.

[0048] Step S104: if the link to be visited is not the first visited link, determine that the link to be visited is a target link.

[0049] Here, if the link to be visited is not the first time to visit the link, it means that the enterprise contact information can be directly obtained from the link to be visited, and the link to be visited is the target link.

[0050] Step S105: open the second display page corresponding to the target link, and extract the target enterprise information in the second display page.

[0051] Here, the target enterprise information includes enterprise contact information, web page snapshot files, and hash values ​​of page bytecodes of the enterprise's official website.

[0052] The second display page is a page containing the company's contact information.

[0053] In one embodiment, referring to Figure 3 When the target enterprise information is enterprise contact information, the steps of step S105 include:

[0054] Step S301, accessing a second display page corresponding to a target link.

[0055] Step S302: extracting the enterprise contact information in the second display page according to a preset regular expression.

[0056] Here, the company contact information can be telephone number, mobile phone number, email address and QQ number.

[0057] Specifically, the preset regular expressions may include:

[0118] -\\d{2,4}: Again, it means match 2 to 4 consecutive digits.

[0119] -\\b: Indicates a word boundary and is used to match the end position of a number.

[0120] This regular expression can match landline numbers in various formats, for example:

[0121] -400-1234-5678

[0122] -800 1234 5678

[0123] -01012345678

[0124] -021-123456

[0125] -853-1234-5678

[0126] -03791234

[0127] Please note that this regular expression is just a pattern for extracting phone numbers, it does not verify whether the number actually exists or is valid.

[0128] In one embodiment, referring to Figure 4 When the target enterprise information is a web page snapshot file, the steps of step S105 include:

[0129] Step S401, confirming that the loading of the second display page is complete.

[0130] Step S402: traverse all web page content elements in the second display page, and obtain web page snapshot elements corresponding to the web page content elements.

[0131] Here, the webpage content element is obtained by traversing all webpage contents in the second display page according to the webpage content. The webpage content element content can be source code, text, image, video, etc. The webpage snapshot element includes the hypertext markup language HTML source code of the webpage and the resources in the webpage.

[0132] Step S403: synthesize all web page snapshot elements to obtain a web page snapshot file corresponding to the second display page.

[0133] In one embodiment, referring to Figure 5 When the target enterprise information is the hash value of the page bytecode of the enterprise's official website, the steps of step S105 include:

[0134] Step S501, accessing a second display page corresponding to a target link.

[0135] Step S502, encrypt all page bytecodes in the second display page using a preset encryption algorithm to obtain a target hash value of the enterprise official website.

[0136] Here, the preset encryption algorithm may be MD5 (Message Digest Algorithm MD5, message digest algorithm).

[0137] Specifically, the second display page content is converted into a byte array to obtain the bytecode of the second display page. The second display page bytecode is imported into the MD5 library or tool, and the MD5 encryption algorithm provided by the MD5 library is used to take the bytecode of the page as input to calculate the target hash value. This will generate a string consisting of hexadecimal numbers of a fixed length.

[0138] Step S106: compare the target enterprise information with the enterprise information corresponding to the link to be accessed in the preset first database.

[0139] Step S107, if the target enterprise information is different from the enterprise information, update the enterprise information according to the target enterprise information, and subtract the preset step size from the preset weight value of the information collection frequency corresponding to the link to be visited to obtain an updated weight value, so as to update the enterprise information corresponding to the link to be visited based on the updated weight value.

[0140] Here, if the target enterprise information is different from the enterprise information, it means that the enterprise information in the link to be visited has been updated, and the enterprise information is updated according to the target enterprise information, and the information collection frequency is adjusted by adjusting the preset weight value corresponding to the link to be visited.

[0141] The preset step size can be set according to actual conditions, and is set to 1 in this embodiment.

[0142] If the weight value is 1, keep the preset weight value unchanged.

[0143] Here, the preset weight value is at least 1, that is, the link to be visited is visited once every week.

[0144] In one embodiment, the method further comprises:

[0145] If the target enterprise information is the same as the enterprise information, or the enterprise information is empty, the preset weight value of the information collection frequency corresponding to the link to be accessed is kept unchanged.

[0146] Here, when the enterprise information of the enterprise corresponding to the link to be accessed is not updated or the link to be accessed is the first time to be accessed, the information collection frequency and its corresponding preset weight value remain unchanged.

[0147] The embodiment of the present invention provides a method for collecting enterprise information, including: obtaining a link to be visited of an enterprise official website according to a preset weight value of information collection frequency; judging whether the link to be visited is a link to be visited for the first time; if the link to be visited is a link to be visited for the first time, opening a first display page corresponding to the link to be visited, and extracting a target link corresponding to a preset keyword in the first display page through a keyword recognition technology; if the link to be visited is not a link to be visited for the first time, determining that the link to be visited is a target link; opening a second display page corresponding to the target link, and obtaining target enterprise information in the second display page; comparing the target enterprise information with the enterprise information corresponding to the link to be visited in a preset first database; if the target enterprise information is different from the enterprise information, updating the enterprise information according to the target enterprise information, and subtracting a preset step length from a preset weight value of the information collection frequency corresponding to the link to be visited to obtain an updated weight value, so as to update the enterprise information corresponding to the link to be visited based on the updated weight value. In this method, by setting different collection frequencies for enterprise official websites with different update frequencies, and accessing links including enterprise information according to the collection frequencies, enterprise information with different update frequencies can be comprehensively and timely extracted.
