  • 인간이 가진 개념을 지식베이스화하려는 시도 중 하나로 의미망이 구축되고 있다. 한국어를 대상으로 한 어휘 의미망 중 프린스턴 대학의 WordNet을 대역한 KorLex는 1,2단계에서 한국어 어휘의미의 특성을 반영하여 개념 및 의미구조를 재구조화하고 있다. 그러나 현재 KorLex의 동의어 집합을 구성하는 어휘 의미에는 논항정보를 따로 구성할 수 없었다. 본 연구는 세종 전자 사전 격틀정보내의 선택제약조건(selectional restriction)으로 사용되고 있는 의미 부류와 KorLex의 명사 어휘 의미망을 자동 맵핑하는 방안을 제안함으로써 KorLex에서 세종 전자 사전 격틀정보를 활용할 수 있는 가능성을 제공한다.

  • The purpose of the present study is to suggest the meta data of the attribute mapping for interoperability from IFC to CityGML. For this, we analyzed the interoperability issue including the neutral information model structure such as IFC, CityGML. To solve the interoperability problem between IFC and CityGML model which is the neutral GIS format, We proposed the meta data including the mapping rule. The meta data is consists of the connection information between BIM and GIS model, the mapping rule based on the perspective of the use-case, the operator and the attribute. By using this, XML to represent the meta data is defined and the information mapping system is developed.

  • 의미 표지 부착 작업은 구문 표지 부착된 문장의 술어-논항 구조를 파악하여 논항에 적절한 의미역을 부착하는 과정이다. 이 작업을 통하여 생성되는 의미 표지 부착 말뭉치는 의미역 결정에 있어서 절대적으로 필요한 자원이 된다. 의미 표지 부착 말뭉치로는 세계적으로 PropBank가 널리 활용되고 있는데 이를 한국어에 적용시키기 위해서는 PropBank 의미역과 Sejong 의미역 간의 자동 변환이 필요하다. 이전에 제안되었던 이종 의미역 간의 자동변환 방법에서는 명사 계층의 구조 정보를 반영하지 않았다는 문제점이 있었다. 본 논문에서는 이러한 문제점을 보강하기 위하여 명사 계층구조를 반영하여 한국어 PropBank 의미역을 Sejong 의미역으로 자동 변환하는 방법을 제안한다. 제안하는 방법은 PropBank와 Sejong의 맵핑관계 중에서 1:N으로 맵핑되는 PropBank 의미역을 기준으로 명사 계층구조에서 변환 대상 의미역을 가지고 있는 단어와 변환 후보 의미역을 가진 단어들의 개념번호를 뽑아 두 단어 간의 거리를 측정한다. 그리고 레벨 당 가중치를 주어 유사도 계산을 하여 유사도가 적은 값으로 의미역을 자동 변환한다. 본 논문에서 제안하는 방법은 0.8의 성능을 보인다.

  • Software tools for manual 3D projection mapping have been widely used in theme parks and exhibitions. However, no research has been conducted on detailed utilization methods and usability of those tools yet. This study organizes the entire process of manual 3D projection mapping step by step and analyzes the problems that occurred at each step to identify potential improvements of 3D projection mapping tools. First, we introduce the process, which includes: two methods for creating virtual-physical object pairs to construct a virtual environment that is identical to the real-world target of the 3D projection mapping, the production of video textures for special effects, and mapping methods that use semi-automatic projector calibration. In addition, through experiments comparing and analyzing two widely used tools under various conditions for 3D mapping, we identified the technical limitations, performance differences between tools, and issues that impede usability. Finally, we suggest improvements and future research directions to enhance the usability of the 3D projection mapping technology.

  • For 3D modelling artificial objects with computers, we have to draw frames and paint the facet images on each side. In this paper, a geographic modelling system building automatically 3D geographic spaces using GIS data and real images of buildings is proposed. First, the 3D model of terrain is constructed by using TIN and DEM algorithms. The images of buildings are acquired with a camera and its position is estimated using vertical lines of the image and the GIS data. The height of the building is computed with the image and the position of the camera, which used for making up the frames of buildings. The 3D model of the building is obtained by detecting the facet iamges of the building and texture mapping them on the 3D frame. The proposed geographical modeling system is applied to real area and shows its effectiveness.

  • SeaBeam2000, a multibeam echo sounder, is a new generation seabed mapping system of which a single swath covers an angular range of -60.deg. to 60.deg. from the vertical direction with 121 beams. It provides high-density and high-quality bathymetric data along with sidescan acoustic data. The purpose of the research is to develop a system for processing multibeam underwater acoustic and bathymetric data using digital signal processing techniques. Recently obtained multibeam echo sounder data covering a survey area in the East Sea of Korea ($37{\circ}$.00'N to $37{\circ}$30'N and $129{\circ}$40'E to $130{\circ}$30'E) are preliminarily processed using the developed system and reproduced in the raster image format as well as three dimensionally visualized form.

  • Machine vision algorithms, which are composed of noise elimination algorithm, crack detection and mapping algorithm, and path planning algorithm, are required for sealing crack networks effectively and automation of crack sealing.. Noise elimination algorithm is the first step so that computer take cognizance of cracks effectively. Noises should be removed because common road includes a lot of noises(mark of oil, tire, traffic lane, and sealed crack) that make it difficult the computer to acknowledge cracks accurately. The objective of this paper is to propose noise elimination algorithm, prove the efficiency of the algorithm through coding. The result of the coding is represented in this paper as well.

  • In this paper, film uniformity is improved by the bolt-mapping of convolutional image processing between bolts and a film using soft X-ray based in-line LCD TV film thickness controls. The automatic film thickness analysis of 3 inter-bolt's convolution function is proposed for the reduction of offset error from the X-ray changing of line scan in film profiles.

  • Requirement traceability should be continuously maintained in software development and evolution. However, it is usually updated in practice in the quality assurance phase. The gap between "is" and "should" exists due to the fact that developers must invest considerable effort to update requirement traceability while being able to obtain only marginal benefit from the updated traceability. To close this gap, we propose a spreadsheet application that enables developers to flexibly change mappings in a requirement traceability matrix. In this way, developers can reduce their effort in updating the requirement traceability matrix, but still obtain the common form of a requirement traceability matrix on a spreadsheet. The proposed application maintains the mappings between two artifacts on each sheet so that, whenever an artifact item changes, developers can instantly insert the relevant mapping changes. Then, when developers desire the common form of a requirement traceability matrix, the proposed application calculates the mappings among several artifacts and creates the matrix. The application also checks traceability errors and calculates the metrics so that developers can understand the completeness of the matrix. To understand the applicability of the proposed approach, we conducted a case study, which shows that the proposed application can be applied to the real project and easily incorporate the mapping changes.
