개체명 인식이란 주어진 문서에서 개체명의 범위를 찾고 개체명을 분류하는 것이다. 최근 많은 연구는 신경망 모델을 이용하며 하나 이상의 단어로 구성된 개체명을 BIO 표기법으로 표현한다. BIO 표기법은 개체명이 시작되는 단어의 표지에 B(Beginning)-를 붙이고, 개체명에 포함된 그 외의 단어의 표지에는 I(Inside)-를 붙이며, 개체명과 개체명 사이의 모든 단어의 표지를 O로 간주하는 방법이다. BIO 표기법으로 표현된 말뭉치는 O 표지가 90% 이상을 차지하므로 O 표지에 대한 혼잡도가 높아지는 문제와 불균형 학습 문제가 발생된다. 본 논문에서는 BIO 표기법 대신에 BIT 표기법을 제안한다. BIT 표기법이란 BIO 표기법에서 O 표지를 T(Tag) 표지로 변환하는 방법이며 본 논문에서 T 표지는 품사 표지를 나타낸다. 실험을 통해서 BIT 표기법이 거의 모든 경우에 성능이 향상됨을 확인할 수 있었다.

The IHO S-100 is a standard on the universal hydorgraphic data model for supporting information services that integrate various data in maritime and provide proper information for safety of vessels. The S-100 is used to develop S-10x product specifications which are standards on guideline for creation and delivery of specific data set in maritime. The product specification for feature-based data such as ENC(Electronic Navigational Chart) data includes a feature catalogue that describes characteristics of features in that feature-based data. The feature catalogue is developed by domain experts with knowledge on data of the target domain. However, it is not feasible to develop a feature catalogue according to the XML schema by manual. In the IHO TSMAD committee meeting, needs of developing technology on building feature catalogue has been discussed. Therefore, we present a feature catalogue builder that is a GUI(Graphic User Interface) system supporting domain experts to build feature catalogues in XML. The feature catalogue builder is developed to connect with the FCD(Feature Concept Dictionary) register in the IHO(International Hydrographic Organization) GI(Geographic Information) registry. Also, it supports domain experts to select proper feature items based on the relationships between register items.

With the development of e-Commerce and the proliferation of easily accessible information, information filtering systems such as recommender and SDI systems have become popular to prune large information spaces so that users are directed toward those items that best meet their needs and preferences. Until now, many information filtering methods have been proposed to support filtering systems. XML is emerging as a new standard for information. Recently, filtering systems need new approaches in dealing with XML documents. So, in this paper our system suggests a method to create multiform user profiles with XML's ability to represent structure. This system consists of two parts; one is an administrator profile definition part that an administrator defines to analyze users purchase pattern before a transaction such as purchase happens directly. an other is a user profile creation part module which is applied by the defined profile. Administrator profiles are made from DTD information and it is supposed to point the specific part of a document conforming to the DTD. Proposed system builds user's profile more accurately to get adaptability for user's behavior of buying and provide useful product information without inefficient searching based on such user's profile.

In an era of very rapid technological change, standardization organizations have been confronted with the problem that they should develop more new and more complex standards as strategic tools for enforcement of competitive power in shorter time according to the reduction of Life Cycle of products and the increase in the number of standards and their complexity. To cope with this challenge, we introduce the functionalities and development directions for implementing standardization information system. Also this paper describes the architecture of the next generation system for standard information that enabling information sharing and exchanging using XML. Finally, we suggest implementation framework of Standardization Vortal Site for the One-stop service of integrated standards information which provide users with standards development roadmap and give brief introduction to SOL(Standards On-Line) site which is operated by ETRI/PEC.

Recently, workers on construction sites can hardly understand their tasks and the process of the tasks because the construction projects are becoming large and complex. Due to the complexity, workers need a tool that can help them understand their works and some paper-based manuals exist to support them. However, the existing paperbased manuals are not actively used by workers due to the low credibility of information on the manual. In particular, paper-based manual can not be updated frequently because those manuals have to be manually updated by experts. Thus, the credibility of information is decreased and the decrease let the users distrust information of the paper-based manual. Therefore, this research analyzed the feature of wiki-based system and suggested an wiki-based IETM(Interactive Electronic Technical Manual) system model that can be modified by users, and then conducted a survey through a prototype based on urban regeneration project. The result of the survey indicated that wikibased IETM can improve the stakeholder communication by reinforcing the process of creating knowledge as well as knowledge itself.

In this paper, we implement a digital holographic security card system that combines digital holographic memory using random phase encoded reference beams with electrical biometrics. Digitally encoded data including a document, a picture of face, and a fingerprint are recorded by multiplexing of holographic memory. A random phase mask encoding reference beams are used as a decoded key to protect illegal counterfeit. As a result, we can achieve a raw BER of 3.6${\times}$10-4 and shift selectivity of 4${\mu}{\textrm}{m}$ using the 2D random phase mask. Also, we develop a recording pattern and image processing which are suitable for a low cost reader without a position sensing photo-detector for real time data extraction and remove danger of fraud from unauthorized person by comparing the reconstructed holographic data with the live fingerprint data.

In order to use the VR HMD, operation through separate controllers in both hands is required. Methods for text input in VR include a method of selecting virtual keyboard keys on the screen one by one using a controller, a method of inputting through a keyboard that is a resource of a computer by connecting a computer and VR, or a method of inputting through a keyboard that is a resource of a computer by purchasing a wireless keyboard in VR and wireless keyboard connection method. As such, the text input method in current VR equipment causes inconvenience and additional costs to users. For these reasons, most of the VR-related contents are limited to simple functions such as games or viewers, and there is a risk that VR equipment will be recognized as a simple game machine. Therefore, in this study, a multi-input interface using hand tracking provided by the Oculus Quest2 device is designed and partially implemented. Through this, it is expected that various tasks such as document work and business processing as well as games can be conveniently used using VR equipment.

Artificial intelligence-based natural language processing technology is playing an important role in helping users write English-language documents. For academic documents in particular, the English proofreading services should reflect the academic characteristics using formal style and technical terms. But the services usually does not because they are based on general English sentences. In addition, since existing studies are mainly for improving the grammatical completeness, there is a limit of fluency improvement. This study proposes an automatic academic English editing methodology to deliver the clear meaning of sentences based on the use of technical terms. The proposed methodology consists of two phases: misspell correction and fluency improvement. In the first phase, appropriate corrective words are provided according to the input typo and contexts. In the second phase, the fluency of the sentence is improved based on the automatic post-editing model of the bidirectional recurrent neural network that can learn from the pair of the original sentence and the edited sentence. Experiments were performed with actual English editing data, and the superiority of the proposed methodology was verified.

Registration and description of records are important elements of processing which provide with the background information of production of records and business-related information. They also enable to search and use the records. In this paper, I examined the Korean registration and description system defined in the Public Records Management Act which directs the records creating agency to register records in creating offices and directs the "professional archives" to make "basic registrations" and "detailed registrations" of the records. In the analysis and comparison of two different registration and description systems with the known international standards of records and archives management, such as ISO15489 and ISAD(G), I intended to evaluate the Korean records and archives management system and suggested recommendations for the renovation of the Korean recordskeeping system. Despite we have unique office business procedures and the culture of officialdom, and despite we have developed our system based on the established business procedures and office culture, it would be preferable to adopt or follow the international standards and established best practices. After the comparative analysis, I recommended some innovations in the filed of registration and description. For instance, in the basic registration. we would better to install an item of "simple contents summary." We may also need the multiple-level description. The fonds level description and the series level description should be introduced to our archival automated management system. We need to establish a Korean standard of description adopting the rules of the ISAD(G) and ISAAR(CPF). Essential requirements for electronic records management, such as contextual and structural information, should be incorporated in the new standard. Documentation of records disposition also should be reinforced to guarantee the authenticity of records and to ensure control of the records. To implement the recommendations for the standard, we need to amend the Public Records Management Act and its Regulations and Rules. Also it is imperative to redesign the GARS integrated archival automated management system.
