Page Rank is a numerical figure assigned by Google to expressed the importance, relevance and validity of a website based on the number of links pointing at the website. By determining the volume of links pointing to certain websites, Page Rank attempts to determine that site's importance.

Method and device for searching web pages according to tendency values

InactiveCN102110160AIncrease sort weightImprove search satisfactionSpecial data processing applicationsData miningWeb page
The invention discloses a method and a device for searching web pages according to tendency values. The method comprises the following steps of: A), acquiring a plurality of web pages, and downloading the web pages to a web page database; B), performing name identification on characters of the plurality of web pages; C), performing tendency analysis on a plurality of names in the plurality of web pages to acquire the tendency values of the plurality of names of the plurality of web pages; D), making a forward index table, wherein the forward index table comprises the tendency values of the plurality of names; E), making an inverted index table, wherein the inverted index table comprises the tendency values of the plurality of names; F), inputting a search item, and decomposing the search item into at least one keyword; and G) calculating the sequencing weights of the web pages comprising the keywords according to the inverted index table, and outputting a search result. According to the method and the device, the web pages containing the search keywords are mainly sequenced according to the tendency values, so that the web pages with depreciative or ameliorative tendency are sequenced in front, and the search satisfaction of a user is promoted.

Method and system for acquiring individuation characteristics of users and documents

InactiveCN103324648AImprove precisionImprove Information Retrieval EfficiencySpecial data processing applicationsPersonalizationSorting algorithm
The invention provides a method and a system for acquiring individuation characteristics of users and documents. According the method, the individuation characteristics of the users and the documents are updated automatically through signals that the users visit the documents. The individuation characteristics of the users are updated according to the individuation characteristics of the documents which are visited by users; the individuation characteristics of the documents are updated according to the individuation characteristic of the users who visit the documents. According to the acquired individuation characteristics of the users and the documents, optimization is carried out to a webpage sort algorithm so as to realize individuation document sorting; further filtering and screening can be carried out to information acquired from a social networking according to the individuation characteristics of the users and the documents. The invention further provides a system for acquiring the individuation characteristics of the users and the documents. The method provided by the invention has the advantages that the precision ratio of a search engine and the anti-cheating capability of a webpage ranking algorithm can be improved, and the information searching efficiency of the social networking is improved.

Product recommendation method and device, storage medium and electronic equipment

The invention provides a product recommendation method and device, a storage medium and electronic equipment. The method comprises the following steps: determining a node corresponding to a target customer and a node corresponding to each target product which is not purchased by the target customer through a knowledge graph network trained based on a webpage ranking algorithm, and determining a ranking index of the node corresponding to each target product; wherein the ranking index represents the probability that the node corresponding to the target customer walks to the node corresponding tothe target product; and determining a recommendation index of the target product based on the ranking index of the node corresponding to each target product, and selecting a plurality of recommendation products from all the target products according to the recommendation index of each target product to recommend the products to the target customer. By applying the method provided by the invention, the recommended products are determined based on the random walk of the nodes in the network, so that the diversity of the products recommended to customers is improved, the accuracy of personalizedrecommendation is improved, the product recommendation effect is improved, and the service experience is improved.

A Web Page Ranking Method Based on Random Forest Algorithm

The invention provides a webpage sequencing method based on a random forest algorithm. The method includes the steps of obtaining keywords and keyword candidate words corresponding to search webpages;calculating the word frequencies and weights of the keywords or keyword candidate words corresponding to the search webpages; calculating PR values of quality related indexes of the search webpages;calculating pivot values and weight values of the search webpages; calculating the relevance between the recently browsed webpages and the search webpages and the product of TF-IDF values of the keywords and keyword candidate words of the recently browsed webpages; calculating whether an output index is larger than a set threshold or not, wherein the output index is the product of the number of times of a user for browsing the search webpages beyond stipulated access time and a certain function of the webpage staying time meeting the conditions; establishing a random forest model and recordinga corresponding result; calculating final search webpage scores and conducting sequencing. Compared with the prior art, a traditional HITS algorithm is improved to a certain extent by means of a random forest method, the service experience of the user is improved, and information is better and more accurate.
