Data set searching method and device, storage medium and terminal

Abstract

The invention discloses a data set searching method and device, a storage medium and a terminal, and the method comprises the steps: initializing a pre-constructed data connection graph when a query request text is received; generating a query statement vector; calculating semantic distances between the query statement vector and a plurality of data set description vectors in the data connection graph; determining a plurality of second data sets from a plurality of first data sets on a data set layer in the data connection graph based on the data set description vector distance; calculating the similarity between the internal structure of each second data set in a plurality of second data sets and an expansion set formed by the query request text through an external word library layer; and determining a plurality of third data sets from the plurality of second data sets according to the matching degree, and determining the plurality of third data sets as query results of the query request text. Therefore, the problem of low data set search accuracy caused by inconsistency of data set description and data set internal structure in a cross-domain data sharing platform can be solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data set search method, device, storage medium and terminal. Background technique [0002] With the continuous development of information technology, all kinds of information in the living space are recorded in the information system in digital form, forming big data. Due to the different development subjects and management subjects of information systems, it is difficult for the data of each information system to interact with the data of other information systems like isolated islands. Data islands have become an important problem restricting the application of big data. Data sharing is an effective means to solve data islands. The cross-domain data sharing platform brings together a large number of data sets from different fields. Data set search is an important part of the data sharing platform, helping data demanders find the required data sets and improving cro...

Problems solved by technology

This method is suitable for searching low-latitude model data, such as 3D models of aircraft and 3D models of portraits. Text sentences cannot be searched, because text has the characteristics of high latitude and sparseness, and the establishment of grids will face the problem of search space explosion, so it cannot handle user input. The query statement cannot solve the problem of cross-domain data sharing platform dataset search
