The method for realizing information subscription on the Internet of the present invention includes: A. the process of sending the key search information specified by the user to the information search server to subscribe to the information; B. the information search server searches the Internet according to the key information specified by the user. The process of information information; C. The process of pushing the information information searched by the information search server to the user.

The realization method of the present invention has multiple forms, and the system for realizing information subscription on the Internet of the present invention is one of them. In the system, a subscription front-end server and a push server are arranged, and information interaction between the subscription front-end server, the push server and the information search server To realize the information subscription and information push, the information pushed to the user is output to the user through the current instant messaging system commonly used, of course, the information information can also be output to the user through mobile phone text messages, etc.

The system for realizing information subscription on the Internet of the present invention sets an instant messaging client and background server in the information subscription system, combines information subscription with instant messaging tools, and can obtain news information in a timely manner while communicating.

Referring to FIG. 2, FIG. 2 is a schematic structural diagram of an information subscription system according to a preferred embodiment of the present invention. The system includes: an instant messaging client 200 , an instant messaging background server 210 , a subscribing foreground server 220 , an information search server 230 and a push server 240 .

Wherein, the instant messaging client 200 receives its specified search keyword input by the user, and sends it to the subscription front server 220; Subscribed feeds are displayed to the user. In this embodiment, the search keyword is used as the search key information. In practical applications, the search key information such as search key pictures or audio information may also be used.

Subscribe to the foreground server 220, receive the instant messaging client or the user's input on the Web to subscribe to the specified search key information, and store the search key information and subscriber information correspondingly; and forward the stored information to the push server 240 as user subscription information . The subscribing foreground server 220 includes a subscribing user database 221 , and the subscribing user database 221 stores the search key information and subscribing user information received by the subscribing foreground server 220 .

The instant messaging background server 210 receives the instant messaging UDP message containing subscription information sent by the push server 240 and forwards the message to the instant messaging client 200 .

The push server 240 receives and stores the user subscription information forwarded by the subscription front-end server 220, and sends the search keyword in the subscription information to the information search server 230; or receives the information information returned by the information search server 230, queries the stored user subscription information, According to the subscription information of the user, a hypertext link is generated from the obtained news information, and it is packaged into an instant messaging message and sent to the instant messaging background server 210 .

The push server 240 includes a shared memory 241; the shared memory 241 stores user subscription information received by the push server 240.

The push server 240 further periodically queries the subscriber database 221 in the subscription front-end server 220 to obtain new search key information and subscriber information, and uses the information to update the search key information and subscriber information in the shared memory 241 .

Since the user subscription information is stored in the shared memory 241 of the push server 240, when pushing news information to the user, it is not necessary to query the subscriber database 221 every time, but directly query the user subscription information from the shared memory 241, which can speed up Push speed, improve system performance.

The information search server 230 receives the search keywords sent by the push server 240, and searches for news information on the Internet according to the search keywords and stores them; The subscription news information received is returned to push server 240.

The information search server 230 includes an information information database 231 ; the information information database 231 stores information information searched by the information search server 230 .

The news information database 231 is indexed with search keywords. After receiving the search keyword sent by the push server 240, the information search server 230 queries the information information database 231 according to the search keyword, and obtains information subscribed by the user. If when inquiring in information information database 231, do not obtain the user subscription information information that contains search key word, then information search server 230 obtains the user subscription information information relevant with search key word; And record this search key word, update search key word Index, which can facilitate the search server to search for a wider range of information.

By applying the information subscription system shown in Figure 2, information subscription can be realized. The implementation method includes: A. the process of sending key search information specified by the user to the information search server to subscribe to the information information; B. the information search server according to the information specified by the user. The process of searching for key information and searching for news information; C. The process of pushing the news information searched by the news search server to the user.

The above processes will be described in detail below.

First of all, the user subscription information process includes two steps: A1, the subscription front server 220 receives and stores the subscription information of its specified search key information input by the user; and forwards these subscription information to the push server 240;

A2. The push server 240 receives and stores the user subscription information forwarded by the subscription foreground server 220 , and the push server 240 sends the search key information to the information search server 230 .

Refer to FIG. 3 for a specific subscription process. FIG. 3 is a flow chart of a user subscribing to information in the information subscription system shown in FIG. 2 . The process includes the following steps:

In step 301, the instant messaging client 200 receives subscription information input by a user, including search keywords or key images, push type, subscription time, and the like. Here, the push type is set by the user, and can be scheduled push or online push.

Step 302 , the instant messaging client 200 sends the user's subscription information to the subscription front-end server 220 .

Step 303 , the subscription foreground server 220 stores the received subscription information in the subscription user database 221 and sends it to the push server 240 .

Step 304 , the push server 240 stores the subscription information in the shared memory 241 .

The method for the push server 240 to store user subscription information is as follows: store the user's instant messaging number in its shared memory, and store subscription information such as instant messaging number, push type, and search keywords for each subscriber in a data structure.

In steps 301 and 302, the user can also send the subscription information to the subscription front server 220 through the portal website of the information subscription system, that is, the web user.

The process of the information search server searching for information according to the key information is as follows: the information search server receives the search key information sent by the push server, searches the Internet according to the key information, and stores the searched information.

Refer to FIG. 4 for the specific search process. FIG. 4 is a flow chart of searching for information in the information subscription system shown in FIG. 2 . The process includes the following steps:

Step 401 , the push server 240 sends the search keyword to the information search server 230 periodically or irregularly.

Step 402 , the information search server 230 searches the Internet according to the search keyword, and stores the webpage information of the searched information in the information information database 231 . The news information database 231 may use search keywords or search key information of key images as an index.

The information search server 230 may use commonly used keywords to search the server.

After the keyword search server receives the search keywords, its search engine regularly sends spider programs to automatically access the Internet and websites, and crawls to other webpages along the links in the webpages, and collects all the webpages crawled back. The analysis and indexing system program of the search engine analyzes the collected webpages and extracts relevant webpage information, including: URL of the webpage, encoding type, all keywords reported in the webpage content, keyword position, generation time, size, and others The link relation of webpage etc., carry out a large amount of complicated calculations according to the correlation method algorithm of search engine, obtain the relevancy degree of each webpage to the keyword in the webpage content and hyperlink, then use these relevant information to build webpage index database and it is exactly the present invention The information database 231 .

The search system program of the search engine receives the user's search keyword sent by the push server 240, and finds all relevant webpage information matching the keyword from the webpage index database. Because the relevance of all relevant webpages for this keyword has already been calculated, the push server 240 only needs to sort according to the ready-made relevance values, and the ones with higher relevance are ranked first, and the number of items received according to the user's selection, Generate web pages.

The process of pushing the news information searched by the news search server to the user includes the following steps:

C1. The push server sends the search key information in the user's subscription information to the information search server;

C2. The information search server queries the stored information according to the search key information, obtains the subscribed information, and returns the obtained subscribed information to the push server;

C3. The push server queries the recorded user subscription information, and obtains the subscription information information of each subscriber from the subscription information information returned by the search server according to the subscriber information;

C4. The push server generates hypertext links for each user's subscription information;

C5. Pushing the hypertext link to the user.

In this embodiment, the push server 240 encapsulates the hypertext link into an instant messaging message and sends it to the instant messaging background server 210; the instant messaging background server 210 forwards the message to the instant messaging client 200, and the instant messaging client 200 sends The information subscribed by the user is output to the user.

The push server 240 supports two push types: scheduled push and online return.

Timing push is a way for the push server 240 to actively push without considering whether the user is online or not.

Referring to FIG. 5 , FIG. 5 is a flow chart of timing push processing of the push service in the information subscription system shown in FIG. 2 .

The scheduled push process includes the following steps:

Step 501 , the push server 240 regularly reads out all the user information that needs to be pushed at that moment from the shared memory, and transmits the keywords one by one to the information database 231 in the information search server 230 to inquire about subscribed information.

Step 502, according to the subscription information of each user in the shared memory, the push server 240 generates hypertext information one by one according to the information information of the user returned by the information search server 230 according to the instant messaging number of the user. link, and encapsulate it into an instant messaging UDP message and send it to the instant messaging background server 210.

Step 503, the instant messaging background server 210 judges whether each user is online, and sends the above-mentioned instant messaging message containing web page information to the instant messaging client 200 for the online user; stores the message for the offline user, and waits for the user to go online Retweet later.

In this way, the user only needs to click on the message logo to browse the subscribed information through the browsing tool of the client.

Online push is a way for the push server to push subscription information to the online users after receiving the new online user information sent by the instant messaging server.

Referring to FIG. 6 , FIG. 6 is a flow chart of online push processing in the push service of the information subscription system shown in FIG. 2 . The process includes the following steps:

In step 601 , the instant messaging background server 210 notifies the push server 240 to push the new user online after receiving the new user's online message sent by the instant messaging client 200 .

In step 602, the push server 240 queries the instant messaging background server 210 to obtain the latest online user information.

When a user registers as an instant messaging user, the user information is inserted into the user database 211 through the instant messaging background server 210 .

The database can be SQL Server, Oracle, Mysql and other commonly used database software. When a user logs in, the instant messaging background server 210 receives a notification that the user is online, puts the online user ID into a queue created in memory, and provides a TCP/IP access interface. Other servers can query the online queue service to collect User information currently logged into the system, that is, which users are online users.

The push server 240 queries the information of the online queue from the instant messaging background server 210, and then puts the information into the shared queue of the thread pool of the online push server 240.

Step 603, the push server 240 selects an online user, and judges whether the user requires online push according to the subscription information in the shared memory 241, and if so, executes step 604, otherwise repeats this step, and selects the next online user.

Step 604 , the push server 240 transmits the user's keyword to the news information database 231 in the news search server 230 to inquire about subscribed news information.

Step 605, according to the subscription information of the user in the shared memory, generate a hypertext link to the information information of the user returned by the information search server 230, that is, the webpage information, according to the queried information information according to the user instant messaging number of the user, and Package it into an instant messaging message and send it to the instant messaging background server 210.

Step 606 , the instant messaging background server 210 sends the UDP message containing information information to the instant messaging client 200 .

In this way, the user only needs to click on the message logo to browse the subscribed information through the browsing tool of the client.

In step 607, the push server 240 judges whether there are any unselected online users, and if so, returns to step 603, otherwise ends the push process.

In addition, in the above two pushing processes, when the information search server 230 inquires about information information, there may not be subscription information information that completely contains the search keyword in the information information database 231, and the information search server 230 will send the information related to the search keyword The news information is returned to the push server; and the search keyword is recorded, and the search keyword index is updated. In this way, it is convenient for the information search server 230 to search for a wider range of information.

It can be seen from the above embodiments that the method for realizing information subscription on the Internet of the present invention adopts the key information search technology, is highly targeted, and can meet the personalized needs of users. The system for realizing information subscription on the Internet of the present invention sets the instant messaging client and background server in the information subscription system, combines information subscription with instant messaging tools, and can directly obtain news information while communicating, The receiving method is simple and convenient.
