Safer Together: Machine Learning Models Trained on Shared Accident Datasets Predict Construction Injuries Better than Company-Specific Models

no code implementations9 Jan 2023 Antoine J. -P. Tixier, Matthew R. Hallowell

In this study, we capitalized on a collective dataset repository of 57k accidents from 9 companies belonging to 3 domains and tested whether models trained on multiple datasets (generic models) predicted safety outcomes better than the company-specific models.

AI-based Prediction of Independent Construction Safety Outcomes from Universal Attributes

no code implementations16 Aug 2019 Henrietta Baker, Matthew R. Hallowell, Antoine J. -P. Tixier

This paper significantly improves on, and finishes to validate, an approach proposed in previous research in which safety outcomes were predicted from attributes with machine learning.

Automatically Learning Construction Injury Precursors from Text

no code implementations26 Jul 2019 Henrietta Baker, Matthew R. Hallowell, Antoine J. -P. Tixier

In light of the increasing availability of digitally recorded safety reports in the construction industry, it is important to develop methods to exploit these data to improve our understanding of safety incidents and ability to learn from them.

Word Embeddings for the Construction Domain

1 code implementation28 Oct 2016 Antoine J. -P. Tixier, Michalis Vazirgiannis, Matthew R. Hallowell

Our vectors were obtained by running word2vec on an 11M-word corpus that we created from scratch by leveraging freely-accessible online sources of construction-related text.

Construction Safety Risk Modeling and Simulation

no code implementations26 Sep 2016 Antoine J. -P. Tixier, Matthew R. Hallowell, Balaji Rajagopalan

By applying our methodology on an attribute and outcome dataset directly obtained from 814 injury reports, we show that the frequency-magnitude distribution of construction safety risk is very similar to that of natural phenomena such as precipitation or earthquakes.
