Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0049] When dealing with BIM model information in the prior art, it is impossible to properly distinguish the degree of similarity of similar words, so that when searching and locating similar words, ideal results are often not obtained. The present invention proposes a BIM semantic disambiguation method, figure 1 is a schematic flow chart of the BIM semantic disambiguation method provided b...

Abstract

The invention provides a BIM semantic disambiguation method and system, and the method comprises the steps: obtaining a BIM vocabulary set, and building a vector space of the BIM vocabulary set; obtaining a vocabulary to be queried, and determining a vocabulary vector of the vocabulary to be queried; and calculating an editing distance of the vocabulary vector relative to the vector space, and determining the most similar vocabulary of the to-be-queried vocabulary according to the editing distance. According to the method, the vector space is introduced into the BIM model to calculate the similarity between the word groups, and the editing distance is introduced to perform mixed weighting, so that a relatively good comparison effect can be achieved when similar words are compared.

Description

technical field [0001] The present invention relates to the technical field of BIM (Building Information Modeling, building information model) data processing, in particular to a BIM semantic disambiguation method and system. Background technique [0002] In the BIM domain model information, there are usually problems with synonyms and different words. People can easily understand the difference between the two and know that the meanings expressed are the same, but it is difficult for machines to align the semantics of the same components. [0003] For example, "structural material" can be split into two words "structure" and "material". In the BIM semantic environment, it is necessary to compare the similarity of phrases; in addition, there will be errors in form and word due to user input errors. Other word problems, such as "structure" and "knot hook", also need to identify the similarity between similar words, so as to effectively distinguish. [0004] Therefore, it is ...
