컴퓨터의 보급과 활용이 늘어남에 따라 한글과 영문이 혼합된 문서 작성의 필요성이 계속 증대되고 있다. 컴퓨터 하드웨어 및 소프트웨어에서 사용자의 편리성과 효율성을 최대한 배려하는 "사용자 인터페이스"에 대한 연구가 증대되고 있어서 보다 편리한 한/영 혼용문서의 작성 방법이 요구되고 있다. 키보드를 통한 한/영 혼용문 입력시에 입력된 문서의 내용을 입력 오토마타 및 사전 수록 정보를 토대로 분석하여 자동적으로 한글 또는 영문으로 변환하는 자동토글 시스템 개발에 대해 설명하고, 현재의 시스템이 해결하지 못한 문제점 및 개선 방향을 기술한다.

본 논문은 다양한 활자체 및 크기의 한글 문자 영상에서의 정보량 및 엔트로피의 분포에 관한 연구이다. 12 종류의 서로 다른 활자체 및 크기의 한글 문자 영상이 실험에 사용되었으며, 사용 빈도수가 높은 520 자의 한글 문자 영상에 대하여 정보량과 엔트로피를 측정하였다. 실험 결과의 분석을 통하여 정보량과 엔트로피의 측정치는 문자의 구조적 형태에 따라 변하지만 활자체에는 무관하며, 대부분의 정보량이 문자의 가장자리 부분에 위치함을 알 수 있었다.

기계 인쇄된 문서 영상에서 주제어를 탐색하는 문제는 여러 응용 분야에 필수적인 핵심 기술이지만 수작업 또는 OCR 소프트웨어를 이용하여 텍스트로 변환하는 방법은 많은 비용 때문에 한계를 가지고 있다. 요즘 영상 형태로 원문을 저장하는 경우가 많으므로 본 논문은 영상-기반 매칭을 통한 검색 방법을 채택하였다. 문자 또는 단어 매칭에서 가장 중요한 요소가 특징인데 본 논문에서는 디지털도서관과 같이 매칭 대상 단어가 수천만∼수십억에 달하는 대용량 한글 문서 검색에 이용될 수 있도록 비교적 간단히 추출할 수 있고 차원수 조절이 용이한 4방향 프로파일 특징을 이용하는 빠른 검색 방법을 제안한다. 실험결과 8-차원 정도의 간단한 특징으로도 의미 있는 검색 성능을 얻을 수 있음을 보였다.

A new integrated coding method is proposed in this study for embedding the text information including Hangul into an image. A monochrome analog image may be quantized to a few leveled digital image and be displayed on bi-leveled output devices by using halftone processing techniques. Text data are embedded on each micro pattern. Based on this concept, the encoding and the decoding algorithm are implemented and experiments are performed. As a result, the average amount of the embedded text information is more than 8 bpp (bits per pixer) in this halftone processed image converted form a $64{\times}64$ image, i.e, corresponding to 2000 characters in Hangul, or 4000 characters in alphanumeral. using this algorithm, the integrated personal record management system is implemented.

Purpose The research was studied the hierarchical Hangul emotion index by organizing all the emotions which SNS users are thinking. As a preliminary study by the researcher, the English-based Plutchick (1980)'s emotional standard was reinterpreted in Korean, and a hashtag with implicit meaning on SNS was studied. To build a multidimensional emotion dictionary and classify three-dimensional emotions, an emotion seed was selected for the composition of seven emotion sets, and an emotion word dictionary was constructed by collecting SNS hashtags derived from each emotion seed. We also want to explore the priority of each Hangul emotion index. Design/methodology/approach In the process of transforming the matrix through the vector process of words constituting the sentence, weights were extracted using TF-IDF (Term Frequency Inverse Document Frequency), and the dimension reduction technique of the matrix in the emotion set was NMF (Nonnegative Matrix Factorization) algorithm. The emotional dimension was solved by using the characteristic value of the emotional word. The cosine distance algorithm was used to measure the distance between vectors by measuring the similarity of emotion words in the emotion set. Findings Customer needs analysis is a force to read changes in emotions, and Korean emotion word research is the customer's needs. In addition, the ranking of the emotion words within the emotion set will be a special criterion for reading the depth of the emotion. The sentiment index study of this research believes that by providing companies with effective information for emotional marketing, new business opportunities will be expanded and valued. In addition, if the emotion dictionary is eventually connected to the emotional DNA of the product, it will be possible to define the "emotional DNA", which is a set of emotions that the product should have.

Accordmg to the development of various information retneval system suitable for Korean database, many researchers have realized the need of R Test ColleAon which can be r d y used for evaluatmg a retneval system. Therefore, This study developed the TEST SET whch helps ob&vely evaluatmg the retrieval performance of an Hangul Automatic Indexer or Korean Information Retrieval System. The developed Test Set has four files such as: 1) Korean Document Set( * . all): 2) Natural Language Query Set(KTsetnq1): 3) Boolean Query Set(Ktset.bq1): 4) Query-Relevance Judgment Set ( KTsetrel) .

There has been some research in Korea on test collections for evaluation of information retrieval (IR) systems. The test collections constructed as an outcome from the research have provided a starting point and opportunities to test Korean IR systems in an objective manner. However, they are well short of the standard practice in the broader IR community in that they are small in their size and usually unbalanced in terms of the characteristics of the documents and the queries (such as the subject domains). In this article, we describe our research effort to alleviate this problem and the resulting test collection, called HANTEC (Hangul TEst Collection). HANTEC is balanced in terms of the subject domains, document lengths, and user types, and currently consists of 120,000 documents divided into three groups: general area, social science area and scienceltechnology area. The 30 queries in the collection are grouped into the same three areas in one dimension and into three distinct user groups in the other dimension.

This study is, by assigning ASCII codes hardly used to Bandaljum(ˇ) and making the fonts of Korean-English character mode, to design the way of converting automatically a word, a sentence or a document of korean into phonetic letters by applying the algorismized phonological principles inputted as a letter string, even though a user do not konw the basic principles of the usage of Korean-to-Romanization notation rule. This is designed so that it may be possible to turn into a mechanical code with reference to the corresponding character in the table of Korean-to-Romanization notation rule that is the currently used standard proposition of the government. Consequently this program makes it user more convenient in the manipulations of special case words, the assistance of colorful-screen or pull-down, pop-up menu and the adoptation of utilizable mouse works for a user convienency. This program could be installed in a single diskette of 5.25"(2HD) and be made in C programming language to mplement various font, expansion or condense of font, alternative printing.ting.

Long time has passed since computers which used to be a means of research were commercialized and available for the general public. People used writing instruments to write before computer was commercialized. However, today a growing number of them are using computers to write instead. Computerized word processing helps write faster and reduces fatigue of hands than writing instruments, making it better fit to making long texts. However, word processing programs are more likely to cause spelling errors by the mistake of users. Spelling errors distort the shape of words, making it easy for the writer to find and correct directly, but those caused due to users' lack of knowledge or those hard to find may make it almost impossible to produce a document free of spelling errors. However, spelling errors in important documents such as theses or business proposals may lead to falling reliability. Consequently, it is necessary to conduct research on high-level spelling error correction programs for the general public. This study was designed to produce a system to correct sentence-level spelling errors to normal words with Korean alphabet similarity algorithm. On the basis of findings reported in related literatures that corrected words are significantly similar to misspelled words in form, spelling errors were extracted from a corpus. Extracted corrected words were replaced with misspelled ones to correct spelling errors with spelling error detection algorithm.
