Abstract

The invention discloses an automatic intelligent generation and recommendation method for data news; the feature extraction of unstructured data mainly comprises the steps of text denoising and duplicate removal, and LDA document topic model generation; the effective integration mode of the multi-source data mainly comprises a data integration method which can be any public; a community structure in a dynamic network is found through an efficient community discovery algorithm, performing evolution analysis on a community, and the dynamic characteristics of a community evolution process is found; then network structure features are fused into a traditional time sequence method, so that the evaluation accuracy for the platform attention degree is improved. According to the method, for the problem of calculation complexity, a graph approximation algorithm is utilized to describe a stationary evolution paragraph in timeline, and then the optimal audience is quickly found in combination with influence maximization in information propagation. For the problem of data sparsity, network features are fused into a time sequence analysis method, corresponding constraints are added, the influence of noise and randomness is reduced, and the prediction effect is improved.

Description

technical field [0001] The invention relates to a method for automatically and intelligently generating and recommending data news, which belongs to the technical field of big data applications. Background technique [0002] The results of journalists' mining and processing of big data can present such news (big data news) through complex interactive and dynamic pictures and videos. [0003] It is not difficult to obtain public data, but it is very difficult to collect a large amount of public data that is really helpful for business decision-making. Searching, sorting, mining, presenting the relationship among them, and presenting a concrete result, this The difficulty is even greater, so we need a more efficient and direct method to help us convert messy information into decision support. As an important application field and scenario of public big data, the media, especially investigative journalists, have an urgent need for public big data. This group has always hoped t...
