- the invention relates to a search engine ranking method based on user participation, and belongs to the technical field of software.
- search engine plays an important role in everyone's daily online life.
- An excellent search engine can discover real knowledge from huge amounts of information like junk, and improve the value of information through the screening, processing and purification of information.
- search engine correlation ranking algorithms are not perfect, users often need to manually select relevant web pages from a large number of returned results, and the search engine navigation function does not play a significant advantage.
- the ranking of search results is based on the order in which search engines find matching pages in the database. There is no guarantee that the top-ranked pages are more relevant to user queries, so they cannot help users from overloading. Quickly pick up really relevant information in the message.
- the number of web pages visited by search engines has reached the scale of one billion.
- the search results contain thousands of web pages. Even if these web pages are required by users, users cannot browse all web pages. How to put more relevant web pages in front, reducing the number of users browsing the web and helping them find the information they need quickly is a meaningful and challenging task. Users usually only care about the top documents returned by the search engine. So research the search engine's relevance sorting algorithm, and rank the results expected by users. Being listed in the front is becoming more and more important.
- Search engines not only need to return search results, but also reprocess these results to determine which ones are more in line with the user's search intent, and arrange the documents that users are most interested in, so that users can find the information they need in the shortest time and improve the search engine. User satisfaction.
- This is the relevance principle of search engines and has been used as one of the most basic principles of search engines.
- the search engine relevance ranking model includes Boolean model, vector space model, probability model, hyperlink model, and self-learning sorting model.
- the Boolean model is based on classical set theory and Boolean algebra. It judges whether the documents are related according to whether keywords appear in the document. All relevant documents are related to the query in the same degree, so the relevance sorting is not supported.
- the vector space model converts the document and the user query into a vector form, calculates the cosine of the two vectors, and arranges the documents in descending order.
- the probability model ranks all documents based on the probability of association by estimating the probability that the document is associated with the query.
- the hyperlink model calculates the page rank based on the hyperlinks between the web pages, and determines the level of the page from the number of links and the quality of the linked pages.
- the self-learning sorting model applies the machine learning method to the search engine relevance ranking problem, and solves many of the shortcomings of the previous model. It learns the sorting model based on the training samples, and then predicts the sorting model to predict the document related to the query.
- Hyperlink analysis that is, the more times a web page is linked and the more authoritative the link is, the higher the quality of the web page is.
- the frequency of the word frequency is the frequency of the query words in the web document. The higher the order, the higher the ranking.
- click-through rate method that is, the more times a web page is clicked, the higher the relevance.
- the purpose of any search engine is Respond to user searches more quickly, and feed back search results that meet user needs to search users.
- the ability to prioritize high-quality documents that are most relevant to user retrieval needs is one of the key techniques for measuring search engine performance.
- the object of the present invention is to provide a search engine ranking method based on user participation, according to the user's participation in the evaluation of the search list, and to rank and rank the evaluation results, and to conveniently search for the corresponding results according to the results of the user participation evaluation, which is convenient for people to Need to use.

- User's method of scoring list information includes: user identification, list number, rating, time stamp.
- Model data includes two types:
- Model input data The core of the search engine ranking system is the search engine sorting algorithm model. However, because different algorithms require different input data, the input data of the system needs to be preprocessed and sorted into model input data. It mainly includes: user, list information, and rating data.
- the user data converts the user information into a form required by the algorithm model, and specifically includes: a user identifier, an age group, a gender indicator, and a career indicator; wherein the age, gender, and occupation are data corresponding to the user information preprocessed by the model data. form.
- List data converts list information into the form required by the model, including: List number, type I, type 2, - type M.
- Scoring data User rating data needs to be processed into a scoring matrix, including user number, list 1 score, list score 2 ⁇ score K. The rating data of each user is expressed in the form of a row vector.

It consists of two parts, one part is the classification result of the original user, including the user number, model label and classification number. The other part is the classification result of the classification, including model number, classification number, list 1 rating, list 2 rating... list ⁇ rating.
- User prediction score data The output of the search engine ranking system is the application model to perform user prediction, and output the search engine ranking result. According to the input data and model data of the search engine ranking system, the search engine ranking results of the predicted users are calculated, including the user number, the model identifier, the classification number, the list number, and the score.
- Predict new list user data Predict user classes that may be of interest based on the characteristics of the new list and user rating information.

This added information will appear on a certain page location.
- the search results are listed on the right or after the search results with high scores, and the results are also scored by other users. The score determines the order in which they are arranged.
- new user refers to the search engine sorting system does not exist any of its rating data, including two types of users, one is a newly registered user, the other is registered but not carried out Rating users.
- the search engine ranking for new users uses a model based on user information.
- the search engine results are predicted based on the output of the model and the input data.
- Online search engine sorting uses a real-time search engine sorting mode for search engine sorting. When the user logs into the search engine ranking system website and browses the page, the user's rating data is directly read, the list of interest to the user is predicted, and the user is directly fed back to the list that the user is most likely to be interested in.
