Self-adaptive Chinese word segmentation method and device for building information model

Abstract

The embodiment of the invention provides a self-adaptive Chinese word segmentation method and a device for building information model. The method comprises the steps of constructing a BIM model dictionary according to a target BIM model; embedding a pre-constructed building domain term dictionary and the BIM model dictionary into a pre-trained Chinese word segmentation model; and performing word segmentation on to-be-segmented sentences in the building field based on the Chinese word segmentation model embedded with the BIM model dictionary and the building field term dictionary. According tothe method of the invention, when data mining needs to be carried out on the BIM model, the Chinese word segmentation model is optimized by using the feature information actually used in the BIM modelin a targeted manner; the word segmentation result is more suitable for data mining of the BIM, self-adaptive Chinese word segmentation of the BIM is achieved, the efficiency and accuracy of Chineseword segmentation in the field of building information are improved, the universality of existing BIM retrieval, entity matching and other methods can be improved, and the application range of the methods is widened.

Description

technical field [0001] The invention belongs to the technical field of natural language processing, and in particular relates to a method and device for building information model adaptive Chinese word segmentation. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is a digital information model that records the physical and functional characteristics of building facilities. BIM contains detailed information of each stage in the building life cycle, realizes the interoperability of building life cycle data, and promotes the effective collaboration of all participants in the construction project. At present, BIM has become an effective solution and an important trend of engineering informatization in the construction industry (Architecture, Engineering and Construction, AEC), and has been extensively researched and applied in construction companies. [0003] Usually, a BIM model records the complete data information of an engine...
