In this paper, we propose a new adaptative pruning algorithm which effectively reduces the search space during the recognition process. As maximum probabilities between neighbor frames are highly interrelated, an efficient pruning threshold value can be obtained from the maximum probabilities of previous frames. The main idea is to update threshold at the present frame by a combination of previous maximum probability and hypotheses probabilities. As present threshold is obtained in on-going recognition process, the algorithm does not need any pre-experiments to find threshold values even when recognition tasks are changed. In addition, the adaptively selected threshold allows an improvement of recognition speed under different environments. The proposed algorithm has been applied to a Korean Address recognition system. Experimental results show that the proposed algorithm reduces the search space of average 14.4% and 9.14% respectively while preserving the recognition accuracy, compared to the previous method of using fixed pruning threshold values and variable pruning threshold values.

Purpose: The purpose of this study is to set the type of 'the New-hanok type Public Buildings' through a case study for the hanok public buildings completed after 2000 years, and to analyze planned properties of the type. This is significant Establishing legal status of 'the New-hanok type Public Buildings' and seeing review of application possibilities of the type for providing a systematic government support measures of 'the New-hanok type public buildings' when models developing future. Method: Method of research is the first to examine the current laws and established the definition and legal status of 'the New-hanok type Public Buildings'. Followed by Setting the type classification criteria as to classify the type of 'the New-hanok type public buildings' and research architectural overview of selected cases by Literature, Internet searches, etc. After systematizing of the types classification of analysis cases, Characteristics of the type of the building structure looks catch classify in spatial structure, function, beauty. Finally, review application possibilities of the type for systematic government support measures establish when models developing of 'the New-hanok type Public Buildings' through a comprehensive analysis. Result: Selected cases were categorized as 3 types according by structural standard based on the core concept of 'the New-hanok type Public Buildings' set in this study. This can be divided into 'Wooden Structure type' and 'Composite structure - Convergence type' and 'Composite structure - juxtaposed type', 'Wooden Structure type' was re-classified by divided into '(1)Traditional Korean Wooden Structure' and '(2)Laminated Wood Wooden Structure'.
