본 연구는 장기간의 남북한 분단으로 인한 언어적 이질성의 정도를 가늠해보기 위하여 남북한 방송언어 비교하였다. 연구의 주 목적은 남북한 언어간 차이에 대한 데이터가 부족한 상황에서 언어사용 실태에 대한 토대 데이터를 제공하는 것이었다. 남북한의 주요 방송사 뉴스 동영상에서 추출한 텍스트를 대상으로 한국어분석프로그램 KLIWC (Korean Linguistic Inquiry and Word Count)으로 분석하였다. 분석 결과, 북한 방송언어는 KLIWC의 각 차원에서 남한 언어와 유의미한 차이를 나타냈으며, 특히 정서적 단어, 인지적 단어, 사회적 단어 등에서 유의미한 차이가 발견되었다. 또한 북한 방송에서는 인칭대명사나 품사와 같은 언어학적 기능어에 있어서도 남한방송보다 사용빈도가 높았다. 이러한 차이에 대한 예비적인 심리학적 신문방송학적 해석을 제공하였다.

As the rapid development of the Internet, the embedded images in HTML web pages nowadays become predominant. For its amazing function in describing the content and attracting attention, images become substantially important in web pages. All these images consist a considerable database. What's more, the semantic meanings of images are well presented by the surrounding text and links. But only a small minority of these images have precise assigned keyphrases. and manually assigning keyphrases to existing images is very laborious. Therefore it is highly desirable to automate the keyphrases extraction process. In this paper, we first introduce WWW image annotation methods, based on low level features, page tags, overall word frequency and local word frequency. Then we put forward our method of multi-cues integration image annotation. Also, show multi-cue image annotation method is more superior than other method through an experiment.

An efficient method of estimating the spatial gaps between the connected components has been prposed to separatethe individual words from a handwritten legal amount on bank check. Owing to the inherent problem of underestimation or overestimation, the previous gap measures have much difficulty in being applied to the legal amounts that usually include the great shape variability by writer's unconstrained writing style and touching or irregular gaps between words by space limitation. In order to alleviate such burden and improve word separation performance, we have developed a modified version of each distance measure. Through a series of word separation experiments, we found that the modified distance measures show a better performance with over $2-3\%$ of the word separation rate than their corresponding original distance measures.

수화는 하나의 제스처가 하나의 단어를 나타내는 수화 단어와 한글을 알파벳으로 표현하는 지문자로 구성되어 있다. 본 논문에서는 USB 카메라로부터 촬영한 영상을 얻고 히스토그램을 이용하여 피부색 영역을 추출한다. 얼굴 영역 추적을 활용하여 이미지를 그리드화하고 지문자의 위치를 파악하여 초성, 중성, 종성을 구분하고 한글 음절을 구성하였다.

This study compared South and North Korean broadcasting languages to measure the language differences due to the long segregation. This study would provide fundamental database on the language uses between South and North Korea. The KLIWC analyzed the text that was selected from news clips of South and North Korean broadcasting agencies. The results showed that North Korean languages were significantly different from South in terms of affective, cognitive, and social words. In addition, North Korean broadcasting used more person pronoun and a part of speech than South Korean broadcasting. Psychological interpretations were provided based on the language differences.

In this paper, we propose a method for the postprocessing of cursive script recognition in Wine Label Images. The proposed method mainly consists of three steps: combination matrix generation, character combination filtering, string matching. Firstly, the combination matrix generation step detects all possible combinations from a recognition result for each of the pieces. Secondly, the unnecessary information in the combination matrix is removed by comparing with bigram of word in the lexicon. Finally, string matching step decides the identity of result as a best matched word in the lexicon based on the levenshtein distance. An experimental result shows that the recognition accuracy is 85.8%.

In order to recommend contents, the company generally uses collaborative filtering that takes into account both user preferences and video (item) similarities. Such services are primarily intended to facilitate user convenience by leveraging personal preferences such as user search keywords and viewing time. It will also be ranked around the keywords specified in the video. However, there is a limit to analyzing video similarities using limited keywords. In such cases, the problem becomes serious if the specified keyword does not properly reflect the item. In this paper, I would like to propose a system that identifies the characteristics of a video as it is by the system without human intervention, and analyzes and recommends similarities between videos. The proposed system analyzes similarities by taking into account all words (keywords) that have different meanings from training videos, and in such cases, the methods handled by big data clusters are applied because of the large scale of data and operations.

Information on movement of objects in videos can be used as an important part in categorizing and separating the contents of a scene. This paper is proposing a shape-based movement-matching algorithm to effectively find the movement of an object in video streams. Information on object movement is extracted from the object boundaries from the input video frames becoming expressed in continuous 2D shape information while individual 2D shape information is converted into a lD shape feature using the shape descriptor. Object movement in video can be found as simply as searching for a word in a text without a separate movement segmentation process using the sequence of the shape descriptor listed according to order. The performance comparison results with the MPEG-7 shape variation descriptor showed that the proposed method can effectively express the movement information of the object and can be applied to movement search and analysis applications.

In this paper we have proposed the sign language transformation system for deaf based on a morpheme analysis. The proposed system extracts phoneme components and connection informations of the input character sequence by using a morpheme analysis. And then the sign image obtained by component analysis is correctly and automatically generated through the sign image database. For the effective sign language transformation, the language description dictionary which consists of a morpheme analysis part for analysis of input character sequence and sign language description part for reference of sign language pattern is costructed. To avoid the duplicating sign language pattern, the pattern is classified a basic, a compound and a similar sign word. The computer simulation shows the usefulness of the proposed system.

본 논문은 최근 연구가 고조되고 있는 지적 인터페이스에 대한 연구로서, 장애인 복지와 공학적인 일반성을 고려하여 수화를 인식하였다. 장애인의 수화를 인식한다는 입장에서 심리적 부담을주지 않고 최소한의 제한조건만을 설정하여 수화의 흑백동영상을 입력으로 하였다. 수화인식에서 손의 형상과 움직임 방향정보가 제일 중요함을 감안하여 각각 그 정보를 추출하고 인식에 적용하는 방법을 개발하여 그 유효성을 보였다. 즉 형상정보의 추출 및 인식에 대해서는 형상정보만이 중요한 수화 지문자 자음 14자를 대상으로 하여 인식하는 과저을 보였다. 또한 손의 움직임 정보에 대해서는 움직임 방향마이 중요한 정보가되는 간단한 수화 단어 9개를 대상으로 인식하여 그 과정과 방법을 보였다.
