Description
Technical Field
The present invention relates to the field of network technologies, and in particular, to an information matching method and apparatus.
Background
With the continuous development of society, the internet becomes an indispensable part of people's lives, and users have increasingly high requirements on the accuracy of information obtained by using search engines on the internet.
When performing keyword ranking analysis of Search Engine Optimization (SEO), obtaining link information of a phrase in a designated Search Engine through a crawler program according to the phrase and a Uniform Resource Locator (URL) input by a user, and then matching the link information with the URL input by the user.
In the prior art, the general matching process is as follows: firstly preprocessing the URL input by the user and the crawled URL, secondly comparing the URL input by the user and the crawled URL, and finally finishing matching if the URL input by the user and the crawled URL are equal. The search engine acquires information by judging the legality of the URL through preprocessing, and directly matching the URL according to the input URL of a user after preprocessing. The URL preprocessing mainly judges the legality of the URL, and a regular expression is generally adopted to match all parts of the URL to judge whether the URL is legal or not. Since the URL must be preceded by a specific protocol in the prior art, and the address cannot contain double bytes or non-link special characters, it may cause a situation that the URL is not clear or understood incorrectly by using the regular expression. The search results of the search engine are used in a mode of reflecting the webpage ranking according to the relevance of characters, words and phrases, namely, when keyword ranking is carried out, various matching rules occur, so that the matching is not flexible, and the URL input by a user is directly matched in a crawling result set, so that the business requirements are difficult to meet.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As can be seen from the background art, the process of obtaining link information of a phrase in a designated search engine through a crawler technology according to the phrase and a uniform resource locator input by a user and then matching the link information with the uniform resource locator input by the user requires search engine optimization. The search engine optimization is a way of improving the ranking of the current website in the related search engine by using the search rules of the search engine. When matching, the URL input by the user and the crawled URL are needed to be preprocessed, and the URL preprocessing mainly adopts a regular expression to match all parts of the URL, namely, the legality of the URL is judged. The regular expression is used for retrieving and replacing the text which conforms to a certain pattern. When URL preprocessing is carried out in the prior art, the situation that the regular expression is unclear or wrong in understanding the URL can be caused, and various matching rules can be caused when keyword ranking is carried out, so that the matching is not flexible, and the service requirement is difficult to meet. Therefore, the invention discloses an information matching method and device, and aims to achieve the purposes of URL optimization and accurate matching.
Fig. 1 is a schematic flow chart of an information matching method according to an embodiment of the present invention. The information matching method includes the following steps.
Step S101: the method comprises the steps of obtaining a phrase and first URL information input by a user, and obtaining second URL information related to the phrase in a search engine through a crawler technology.
Step S102, unifying symbol formats in the first URL information and the second URL information.
It should be noted that unifying the symbolic formats of the first URL information and the second URL information includes: and uniformly adjusting the symbol formats in the first URL information and the second URL information into a lower case format or an upper case format.
Step S103, removing the protocol, the user name and the password contained in the first URL information and the second URL information.
In a specific implementation, a complete piece of URL information includes: protocol, username, password, domain name, port, path, query terms, and other fragments, etc. For example, a piece of URL information given as follows:
http://lianghonbo:123456@www.gridsum.com:8080/news/sznews/news.html？date＝xx#top＝10。
wherein http is a protocol; lianghonbo:12345 is the username and password; www.grisum.com is a domain name; 8080 is a port; html is a path; is there a date xx is a query condition; and # top 10 is a fragment.
In the process of executing step S103, the protocol, the user name, and the password included in the URL information are removed to obtain: www.gridsum.com 8080/news/sznews/news. htmldate. xx # top. 10.
Optionally, in the process of executing step S103, if it is detected that the first URL information and the second URL information include 80 ports, 80 ports in the first URL information and the second URL information are removed.
Step S104, aligning connection characters between the port information and the path information in the residual information of the first URL information and the second URL information, dividing the residual information into two parts by taking the connection characters as boundaries, wherein the left side of the connection characters is a first part, and the right side of the connection characters is a second part.
The above-described specific process of executing step S104 is exemplified.
If the first URL information of the protocol, the user name and the password is removed is as follows:
gridsum.com:8080/news/sznews/。
the second URL information for removing the protocol, the user name, and the password is:
www.gridsum.com:8080/news/sznews/news.htmldate＝xx#top＝10。
step S104 is performed to align the connection characters "/" between the ports and the paths in the first URL information and the second URL information, and to divide the remaining information of the first URL information and the second URL information into two parts with "/" as a boundary. The left side of the "/" is the first part and the right side of the "/" is the second part. The first part of the first URL information and the first part of the second URL information may be further aligned to the right, and the second part of the first URL information and the second part of the second URL information may be further aligned to the left, and then:
www.gridsum.com:8080/news/sznews/news.htmldate＝xx#top＝10
gridsum.com:8080/news/sznews/
step S105, matching the first part of the first URL information and the first part of the second URL information.
Step S106, matching the second part of the first URL information with the second part of the second URL information.
Step S105 and step S106 may be performed simultaneously or may not be performed simultaneously.
Step S107, if the results of the steps S105 and S106 both satisfy a preset matching condition, determining that the first URL information and the second URL information are matched.
In step S107, the preset matching condition is: the first portion of the second URL information begins with the first portion of the first URL information and the second portion of the second URL information ends with the second portion of the first URL information.
Therefore, in the process of executing step S105 to step S107, if the first part of the second URL information starts with the first part of the first URL information and the second part of the second URL information ends with the second part of the first URL information, it is determined that the first URL information and the second URL information match.
Determining that the first URL information and the second URL information do not match if the first portion of the second URL information does not begin with the first portion of the first URL information or the second portion of the second URL information does not end with the second portion of the first URL information.
For example: the first part of the second URL information is: www.gridsum.com:8080, the second part of the second URL information is: htmldate ═ xx # top ═ 10. The first part of the first URL information is: com:8080, the second part of the first URL information is: news/sznews/. In the matching process, the following results are obtained:
www.gridsum.com:8080/news/sznews/news.htmldate＝xx#top＝10
gridsum.com:8080/news/sznews/
as can be seen from the above example, the matching results in that the first portion of the second URL information begins with the first portion of the first URL information and the second portion of the second URL information ends with the second portion of the first URL information, confirming that the first URL information matches the second URL information.
If the first part of the second URL information is: www.gridsum.com:8080, the second part of the second URL information is: htmldate ═ xx # top ═ 10. The first part of the first URL information is: news. grid. com:8080, the second part of the first URL information is: news/sznews/. Obtained during the matching process
www.gridusm.com:8080/news/sznews/news.htmldate＝xx#top＝10
news.gridsum.com:8080/news/sznews/
As can be seen from the above example, the matching results in that the first portion of the second URL information does not begin with the first portion of the first URL information or the second portion of the second URL information does not end with the second portion of the first URL information, and it is determined that the first URL information and the second URL information do not match.
The embodiment of the invention obtains a phrase and first URL information input by a user, and obtains second URL information related to the phrase in a search engine through a crawler technology; unifying the symbolic formats of the first URL information and the second URL information; removing the protocol, the user name and the password contained in the first URL information and the second URL information, and 80 ports contained in the first URL information and the second URL information detected in the process; aligning connection characters between port information and path information in the residual information of the first URL information and the second URL information, and dividing the residual information into two parts by taking the connection characters as boundaries, wherein the left side of each connection character is a first part, and the right side of each connection character is a second part; and matching the first part of the first URL information with the first part of the second URL information, and matching the second part of the first URL information with the second part of the second URL information, wherein the first URL information and the second URL information are determined to be matched when preset conditions are met. By the information matching method, redundant information in the first URL information and the second URL information is removed, and the obtained first URL information and the obtained second URL information are adjusted and then matched. Not only is the matching of the URL optimized, but also the matching accuracy is improved.
