[0114] Example: figure 1 Shows the JSON data structure diagram returned by the 2018 World Cup REST API. The supplier of the World Cup inJSON API is Software For Good, which is a sports API. Its publishing homepage is http: / / worldcup.sfg.io, and the document homepage URL is https: / / github.com / estiens / world_cup_json . The JSON data structure shown shows the first game information of the 2018 World Cup. fifa_id marks the ID of the game, weather includes the weather information of the game area on the day of the game, attendance indicates the number of spectators in the game, and officials includes the game The staff list of the game, home_team and away_team introduce the information of the two opposing teams in the game, home_team_events and away_team_events include the judgment and penalty events of the opposing teams in the game, home_team_statistics and away_team_statistics include the game against the team in the game Data statistics.

Abstract

The invention discloses a JSON data analysis and modeling method oriented to Web 2.0. The method comprises the following steps that 1, a metadata tree MDT is defined and comprises a root node Troot, an index node INode and a data node DNode, meanwhile, the number of layers of the nodes in a tree structure is expressed through a depth level, and the root node is defaulted to be a first layer, namely the level is equal to 1; secondly, JSON data returned by the called REST API is read, a JSON data set ds is used as input of a modeling algorithm, and tree structure modeling is conducted on ds; and3, through a pruning method, basic data structure information is reserved, the same repeated data structure is cut off, the volume of the model is reduced, but the basic data structure is still reserved, and the query overhead caused by the JSON data structure is reduced. The method is beneficial to accelerating retrieval and positioning of the data, enhancing the accuracy of judging the subordination relation, and improving the data utilization rate and usability.

Description

technical field [0001] The invention relates to a method for parsing and modeling JSON data oriented to Web2.0. Background technique [0002] Web 2.0 is a general term for a new class of Internet applications relative to Web 1.0 (the Internet model before 2003), and it is a revolution from core content to external applications. It has become a new development trend of the Internet from Web1.0 to simply browse html pages through a web browser to the Web2.0 Internet model with richer content, stronger connections and stronger tools. Web 2.0 is a typical embodiment of the future-oriented and people-oriented innovation 2.0 model in the Internet field brought about by the Internet revolution triggered by the development of information technology. [0003] The REST (Representational State Transfer) architectural style was released at the international conference ICSE in 2000. It is an abstract model of Web architecture and is used to guide the redesign and definition of Hypertext...
