An automatic term-network construction system is proposed in this paper. This system uses the statistical values of the terms appeared in a document corpus. The 186 oral history documents collected from the Saemangeum area of Chollapuk-do, Korea, are used for the research. The term relationships presented in the term-network are decided by the cosine similarities of the term vectors. The number of the terms extracted from the documents is about 1700. The system is able to show the term relationships from the term-network as quickly as like a real-time system. The way of this term-network construction is expected as one of the methods to construct the ontology system and to support the semantic retrieval system in the near future.

There are increasing needs for an individual or enterprise to interchange documents electronically through communication network to enhance the efficiency of business, according to the rapid progress in the construction of communication network. UN has established and distributed the standards for electronic documents to facilitate rapid and accurate processing of business. In this paper, we present the design and implementation of an integrated system for processing documents that conform to the electronic document standards. This system consists of three subsystems, which are an EDI parser for checking syntax, an EDI document editor, and an EDI directory viewer for referencing syntax of an EDI document. Integrated usage of these tools can afford the composition of correct EDI documents more rapidly and conveniently.

A new operation strategy. which can guarantee the data consistency of engineering information among the various intelligent information systems, is presented for engineering information of bridges, and construction methodology of integrated database is developed to support the strategy. The two core standard techniques are adopted to construct the integrated database. One is the Standard for the Exchange of Product Model Data (STEP) for CAD/CAE information and the other is the Extensible Markup Language(XML) for engineering document information. The former enabler structural engineers to handle the structural details with three-dimensional geometry-based information of bridges, and ACIS solid modeling kernel is employed to develop AutoCAD based application modules. The latter can make document files into data type for web-based application modules which assist end-users to search and retrieve engineering document data. In addition, relaying algorithm is developed to integrate the two different information, e.g. CAD/CAE information and engineering document information. The pilot application modules are also developed, and a case study subjected to the Han-Nam bridge is presented at the end of the paper to illustrate the use of the developed application modules.

The basic goal of CALS is to improve transactions and relationships among organizations through information sharing and integration. CALS is an information strategy which needs strong cooperation between organizations or between users and developers in design step. However, current design methodologies using IDEF models, that are considered to be standard for CALS system development, has some limitations. For example, it is difficult for system developers to communicate with counterparts by IDEF model since IDEF models are difficult for counterparts to understand. In this paper, we suggest a development methodology for GALS systems by complementing IDEF model with Document Trace Diagram, which we developed as a communication tool, The concept of Document Trace Diagram stems from the fact that most information exchanged within or between organizations is in the form of documents and most standard operating procedures of organizations are about processing the documents. It helps system developers identify functions and their ICOMs (Input, Control, Output, Mechanism) with ease and little communication cost. With this methodology, we have constructed the GALS prototype system for construction industry.

The purpose of this study was to construct the management information system for supporting the supervision of construction workplace. For the purpose, firstly, this study surveyed the present states and the problems of construction workplace in Korea. And then, defined the range and the process of the supervision of construction workplace, and examined the information standards of construction and the CALS standards for supporting. As a result, this study proposed the first stage of management information system, which consists of several basic functions, such as, document management, system management and partially, duality management and construction information management.

The conflict problems encountered in the construction projects led to prolonged delays in implementation, interruptions and sometimes suspension. This paper has described ten fundamental management principles to avoid conflicts in construction field and increase the productivity. They are: i) hire good (not cheap) construction professionals ii) set reasonable time and cost goals iii) recognize contractors and designers are in business to make profit iv) draft a clear contract document v) pick a suitable project delivery system vi) implement a front-end approach vii) accept construction project as a dynamic process viii) need of education and training of professionals ix) accountability and teamwork in construction site, and x) avoid negligence.

VSField-associated term is a single or compound word whose terms occur in any document, and which makes it possible to recognize a field of text by using common knowledge of human. For example, human recognizes the field of document such as or , a field name of text, when she encounters a word 'Pitcher' or 'election', respectively We Proposes an efficient construction method of field-associated terms (FTs) for specializing field to decide a field of text. We could fix document classification scheme from well-classified document database or corpus. Considering focus field we discuss levels and stability ranks of field-associated terms. To construct a balanced FT collection, we construct a single FTs. From the collections we could automatically construct FT's levels, and stability ranks. We propose a new extraction algorithms of FT's for document classification by using FT's concentration rate, its occurrence frequencies.

Specification is an important document for securing safe construction and improving quality as well as the contract document. Currently, the specifications used in modular buildings in Korea are only the construction specification, and most of the contents are used by borrowing the standard specifications of the building, so the contents of the modular buildings can not be reflected and it is contents are similar to the guideline book. The current status of domestic specification for modular buildings is affecting the quality of modular buildings. Therefore, we analyze activity through monitoring the modular process of modular buildings and analyze systematically relationship by applying IDEF modeling with analyzed activity. As result this paper proposes a structure of special specification specialized in modular building through generalization. The major classifications were divided into three stages : factory construction, transportation, and on-site installation. The specification structure was divided into 32 types of construction items from the floor slab assembly of the factory production to the joint finish of the on site installation in accordance with the opinion of experts.

Since risks occurring in construction projects can have a significant impact on schedules and costs, there have been many studies on this topic. However, risk analysis is often limited to only certain construction situations,and experience-dependent decision-making is therefore mainly performed. Data-based analyses have only been partially applied to safety and contract documents. Therefore, in this study, cluster analysis and a Word2Vec algorithm were applied to formal documents that contain important elements for contractors or clients. An initial classification of document content into six types was performed through cluster analysis, and 157 occurrence types were subdivided through application of the Word2Vec algorithm. The derived terms were re-classified into five categories and reviewed as to whether the terms could develop into potential construction risk factors. Identifying potential construction risk factors will be helpful as basic data for process management in the construction industry.
