Building Information Modeling (BIM)-based simulation models have been used to automate lengthy building energy modeling processes and it enable fast acquisition of results. Recent improvements of simulation programs have continued to the increase in the use of energy simulation in sustainability studies at the earlier design stage. However, it is often(More)
This paper presents the results of the development of the duct model based on ASHRAE standard 152-2004 (ASHRAE, 2004) using the DOE-2.1e building energy simulation program. To accomplish this, FUNCTION commands for DOE-2 were used to develop the duct model and provide the improved predictions of the duct heat loss or gain from the unconditioned space as(More)
In this study, we propose a method to validate knowledge candidates using the Web to minimize the false positive rate in a knowledge base (KB). Our approach assesses the objectivity and corrobora-tiveness of a triple, which is the basic form of knowledge, using diverse Web resources. Compared to the state-of-the-art baseline of the Defacto framework, our(More)
Current movie title retrieval models, such as IMDB, mainly focus on utilizing structured or semi-structured data.
