Embodiment Construction

[0023]

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0025] According to the characteristics of actual application and huge amount of data, the present invention adopts the MIIS (Multi-level Inverted Index Structure) inverted index structure based on Hadoop (a distributed system platform with strong distributed storage and computing capabilities), AMPS (Align and Merge Placement Strategy) inverted index and replica placement strategy and PforDelta compression are the basic system platform.

[0026] MIIS inverted index structure, the basic idea is to store the main content of the inverted index file in blocks in the data node, and store the mapping of keywords and block position information in the name node, as well as the collection of documents in a certain period of time and its inverted The mapping of the position information of the data block whe...

Abstract

The embodiment of the invention discloses a big data analysis method based on internet of vehicles. The big data analysis method comprises the following steps: completely splitting input data records to be in the form of attribute lists, sorting for one time, splitting root nodes, completely splitting the attribute lists through circulating splitting, generating a complete decision tree, extracting a tree structure, and generating corresponding mode rules. According to the big data analysis method, data of masses of vehicles can be analyzed; when a request searched by a user is received, data and data combinations required by a user can be quickly analyzed, so that decision aids are provided for the user.

Description

technical field [0001] The invention relates to a data analysis and search method, in particular to a big data analysis method based on the Internet of Vehicles. Background technique [0002] As the number of cars continues to increase, consumers' demand for car safety increases. Car owners' demand for safety is not only the safety and reliability of the vehicle itself, but also those who can provide more safety guarantees through electronic safety products or service technologies. Assisted driving system, the expansion of this demand has led to the gradual expansion of the market's demand for vehicle safety testing. [0003] At present, the current Internet of Vehicles products such as OnStar, Sync, etc. in the existing technology are mainly concentrated on the vehicle terminal, and there are limitations in the services provided to car owners. Each service link is not connected to the Internet or cannot be integrated organically, resulting in a Series of problems: When th...
