thirdly, performing primary sorting on all the articles according to the investigation index n;
step four, judging whether the requirement of the user is met, if the user selects any one of the top five ranked items, representing that the investigation index n meets the requirement of the user, and uploading the investigation index n and the content of the article keywords to an investigation index database in a correlation manner; otherwise, the user requirements are not met, and the next step is carried out;
fifthly, the investigation index weight related to the selected article is increased by m, the investigation index weight related to the article before the ranking of the selected article is reduced by m, and the investigation index weight related to the five articles after the ranking of the selected article is reduced by m
And step six, updating the item sequence according to the recalculated weight, and skipping to step four.
Further, the investigation index n is a number of investigation criteria in the range of 1-10, and the formula m is as follows:
Further, the investigation index database is a cloud server based on IPv6, and sequencing programs related to article initial sequencing and article sequencing update are quick sequencing algorithms written in C + +.
Further, the item keywords are matched and ranked with the investigation index database through a TF-IDF algorithm, and the TF-IDF algorithm comprises the following formula:
the numerator in the formula is the number of occurrences of the keyword in the investigation index, and the denominator is the sum of the number of occurrences of all keywords in the investigation index.
Further, the behavior of actively selecting the item by the user comprises clicking an item link, checking detailed content of the item, sending an item inquiry and purchasing the item, and closing an item page within 10 seconds after clicking the item link does not count the range of the actively selected item by the user.
The invention has the following beneficial effects:
1. according to the method for determining the comprehensive ranking expedition indexes, the core expedition indexes of the articles are updated in real time according to the differences actively selected by the user, so that the article ranking logic is optimized, the articles required by the user are ranked in the front, and the searching efficiency is improved.
2. According to the method for determining the comprehensive sequencing investigation index, the user actively selects to recalculate the weight of the article, the article meeting the user requirement and the core investigation index thereof are brought into the investigation index database, the selection algorithm of the investigation index is convenient to optimize continuously, and the matching completion degree of the article required by the user and the service scene is improved.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
