180 results about "Association list" patented technology

In computer programming and particularly in Lisp, an association list, often referred to as an alist, is a linked list in which each list element (or node) comprises a key and a value. The association list is said to associate the value with the key. In order to find the value associated with a given key, a sequential search is used: each element of the list is searched in turn, starting at the head, until the key is found. Associative lists provide a simple way of implementing an associative array, but are efficient only when the number of keys is very small.

Commodity recommending method of e-commerce website based on keywords

Disclosed is a commodity recommending method of an e-commerce website based on keywords. The method includes entering the e-commerce website through search links when a user searches commodities through a search engine, collecting the keywords and related commodity information carried by the search engine by the e-commerce website through scripts, obtaining an association list of the keywords according to association degree among the keywords, and obtaining an index database through an index relationship between the keywords and related commodities; when a new user visits the e-commerce website through the search engine, analyzing the user referrer to obtain the keywords, obtaining corresponding commodity list through the search of the association list of the keywords and the index database, and recommending N pieces of commodities with the highest weight. The commodity recommending method of the e-commerce website based on the keywords solves the problem of the lack of data of new users through collecting the keywords carried by the search engine of new users, combines the index relationship between the key words and commodities obtained from historical data training, calculates commodity weight according to information such as commodity frequency, and recommends commodities to new users without any behavior records.

Method, apparatus and system for establishing incidence relation between each system of integrated multi-module base station

The invention discloses a method, a device and a system for establishing an incidence relation between various systems of an integrated multi-mode base station. The method of the embodiment comprises the following steps: setting a base station mark for the integrated multi-mode base station, setting a system mark for the systems affiliated to the base station, and reporting the system mark and the base station mark to EMS through OM components of various systems in the integrated multi-mode base station; determining whether the base station exists in a base station mark set by the EMS after receiving the system mark and the base station mark; if yes, recording the system mark on the record of an association list corresponding to the base station mark; and if not, adding the base station mark to the base station mark set, adding the record corresponding to the base station mark to the association list, and recording the system mark to the added record, thereby establishing an association list on the incidence relation between the various systems, and achieving the aim of automatically establishing the incidence relation between the various systems of the integrated multi-mode base station. The process does not need manual configuration of a user, and reduces the cost.

Individualized recommendation method and system based on blockchain integration service platform

The invention discloses an individualized recommendation method and system based on a blockchain integration service platform. The individualized recommendation method comprises the steps that preprocessing is conducted on the data of goods purchased by users, obtaining the preprocessing result; an inverted ordering of goods and users and an association list of users and goods are established based on the preprocessing result; the calculating of user similarity is conducted based on the inverted ordering of goods and users, obtaining a user similarity matrix; characteristic vector extraction processing is conducted based on the association list of users and goods, obtaining user goods characteristic vector information; the user goods characteristic vector information of target user is verified based on the user similarity matrix and the user goods characteristic vector information, obtaining the verified user goods characteristic vector information of target user, and goods are pushedto the target user based on the verified user goods characteristic vector information of target user. The invention is advantageous in that a more accurate personalized recommendation can be realizedthrough effectively utilizing the data advantage brought by the blockchain technology.
