Embodiment Construction
[0018] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. figure 2 Shown is a schematic diagram of a carriage of a train. Two servers are configured in the carriage, and each server has a built-in 500G hard disk. With the advancement of technology, the storage space of the built-in hard disk may become larger and larger. Then these two servers have a large storage capacity, which can store a large amount of video information for passengers to browse and download for free when taking a bus. It is very necessary to understand the real needs of passengers and ensure the popularity and timeliness of video information to improve the service quality of rail transit. In order to achieve the above object, the present invention provides a method for updating video of a subway / high-speed rail vehicle-mounted server oriented to pas...

The invention belongs to the technical field of information, relates to text statistics, text classification and distributed calculation and provides a passengers' demand oriented metro / high-speed rail vehicle-mounted server video updating method. The passengers' demand oriented metro / high-speed rail vehicle-mounted server video updating method mainly comprises two stages, wherein statistics of texts appeared at high frequency is performed at the first stage, namely a parallel distributed statistics method is adopted to conduct statistics on a plurality of search entries appeared at high frequency according to daily search records of passengers, and the search entries are regarded as certainly-popular information currently needed by the passengers; at the second stage, reasonable classification is conducted on the entries searched at high frequency, a reasonable classification method comprises the specific steps of firstly marking a large amount of commonly-used search keywords to establish a sample bank, secondly establishing a text classification model based on the sample bank and finally transmitting the entries searched at high frequency, obtained through statistics, to the classification model to be classified, and the classification purpose aims at facilitating video uploading and browsing and downloading of the passengers.
Description
technical field [0001] The invention belongs to the field of information technology, relates to text statistics, text classification and distributed computing, and is a video update method for a vehicle-mounted server of a subway / high-speed rail oriented to passenger needs. The implementation of the method of the present invention mainly includes two stages. The first stage is the statistics of frequently occurring texts, that is, according to the daily search records of passengers, a parallel distributed statistical method is used to count some search terms with higher frequency of occurrence. Entries are considered to be information with certain popularity that passengers currently need; the second stage is to reasonably classify high-frequency search entries. The specific method is to first mark a large number of commonly used search keywords to build a sample library, and then based on The sample library establishes a text classification model, and finally the statisticall...
