Building knowledge graph database and its construction method

Abstract

The invention relates to a building knowledge mapping database and a construction method thereof. The construction method includes the steps that building data are obtained from one or more data sources and integrated; the building data include building classification class information, building geographic information, building basic information, building owner and user information and crowd searching and label classifying information; the crowd searching and label classifying information is obtained after label classified statistic and index calculation are carried out on the main searching content of crowds in a building; based on the integrated building data, the building knowledge mapping database is constructed; hierarchical classification and structural processing are carried out on the integrated building data; entities in a building knowledge mapping include a building entity, a unit entity, a searching label entity, a searching point location entity and a unit industry entity. The building knowledge mapping database can be beneficial for maintaining and fusing the building data better and effectively using the building data for application programs and data reasoning, and the building data embody matching of the building and audience crowds in the building.

Description

technical field [0001] The invention relates to the technical field of computer databases, in particular to a building knowledge map database and a construction method thereof. Background technique [0002] The development of the Internet has gone through two stages, web1.0 and web2.0, and is developing towards web3.0. web1.0 is characterized by editing, and users read the content provided by the website, which represents the three major portals of Sina, Sohu and NetEase. Web2.0 pays more attention to the interaction of users. Users are not only the consumers (browsers) of website content, but also the creators of website content (Weibo, Tianya community, self-media). [0003] In these two generations of the Internet, the smallest unit that users click to access (or interconnect) is a document, and the connection between documents is realized through hyperlinks; due to the lack of semantics in the HTML language, the content in these two generations of the Internet is mainly...

Problems solved by technology

[0009] The problem to be solved by the present invention is that the building database in the prior art is not conducive to data maintenance and data fusion, it is difficult to be effectively used for application programs and effective data reasoning, and the building data cannot accurately reflect the building and the audience in the building. match
