Recently semantic web document is produced and added in repository in a cloud computing environment and requires an intelligent semantic agent for analytical classification of documents and information retrieval. The traditional methods of information retrieval uses keyword for query and delivers a document list returned by the search. Users carry a heavy workload for examination of contents because a former method of the information retrieval don't provide a lot of semantic similarity information. To solve these problems, we suggest a key word frequency and concept matching based semantic clustering model using hadoop and NoSQL to improve classification accuracy of the similarity. Implementation of our suggested technique in a cloud computing environment offers the ability to classify and discover similar document with improved accuracy of the classification. This suggested model is expected to be use in the semantic web retrieval system construction that can make it more flexible in retrieving proper document.

The scope of e-Commerce process becomes wider as the emphasis on the enterprise collaboration grows. It has expanded from its initial settings of order management or billing processes to cover various collaborative processes in the company's value-chain. In order for those collaborative e-Commerce processes to be successful, corresponding business processes should be fully supported by standard bodies. The RosettaNet consortium, one of the most representative international B2B standard bodies, has steadily provided new PIPs to support those expansions. Since individual RosettaNet PIPs correspond to unit tasks that are executed separately in or between companies, multiple PIPs have to be integrally used to properly handle larger business cases. RosettaNet implementation, however, has suffered from the lack of standard guidelines or deliverables to refer under this multi-PIP environment. In this research, a contents-based document routing system is implemented. By applying this routing system to the RosettaNet e-Logistics program where multi-PIP environment is inevitable, we verified our contents-based document routing system is effective to support multi-PIP environment flexibly.

Nowadays, according to the change of educational environment, an alternative educational system, called cyber university system, is appeared. The appearance of the new system requires the new executive supports for administrative purposes. From this point of view, this paper tries to design and develop an XML-based document management system for the cyber university system. In order to manage and present the multimedia documents for Cyber university effectively, the proposed document management system is divided into 3 hierarchy structures: Generation of Documents, Storage of Documentation, and Search of Documentation. Based on our proposal for the system, the actual implementation is done for the demonstrative purpose. Both the construction of document manage system for the cyber university and modules for portal page are implemented using XML.

As the construction industry becomes bigger and more complicated, standardization of terms should be established between academic and industrial fields in order to accumulate and share information technology. The aim of this study is to investigate and analyze the research trends and actual usage of construction and architectural terms in Korea. For this purpose, we examined research related to construction and architectural terms by searching RISS up to August 2014. We also analyzed document types and contents of research by year. As a result, 130 research studies related to construction and architectural terms were searched. Of document types, glossary ranks the highest, followed by academic journal papers, master's theses and research reports. Research related to construction and architectural terms began in 1939, and was actively studied between the mid-1980s to the mid-1990s. Within the research, list and opinion of related construction and architectural terms are found the most frequently, followed by standardization, analysis, alteration, dictionary and wordbook, and search system of terms. Despite these efforts and research, standardization of terms has not yet been consolidated between academic and industrial fields. Therefor, we suggest six proposals in order to standardize the terms. This study is an attempt to see the trends and conditions of construction and architectural terms and to provide base-line data and an insight for future research.

If slope height was more than 20 meters, we conducted an analysis of stereographic projection and limit equilibrium at this slope. We proposed reduction of slope face angle and reinforcement of rock bolt depending on analysis. Blasting design : Standard pattern based on result of local test blasting was made for blasting design. Vibration criterion was set for less than 3.0mm/s because of outworn buildings and inhabitants opinions. Production blasting and Controlled blasting has been done as Construction standard pattern. After Vibration Monitoring has been done, so that we can control of complement. "Bidding Document" and AASHTO 2001 "A Policy on Geometric Design of Highways and Streets" were so for design criteria of earthwork but they were different actual design criteria and left something to be desired in Afghanistan. Therefore, although "Bidding Document" and "AASHTO 2001" were basic design criteria, domestic design criteria was reflected in this design criteria for complement by discussion with supervisor. Drainage design : For stability ratio, ditch of arch block and stonework was designed by rainfall data for the 13 years and discussion with supervisor. Pavement was designed as flexible pavement. Because these days in Afghanistan postwar repair works, especially urgent repairing of roads and newly making of roads, are very highly in progress, I think that Afghanistan is the region about which our construction technical experts should have great concerns.

With respect to the Semantic Web proposed to overcome the limitation of the Web, OWL has been recommended as the ontology language used to give a well-defined meaning to diverse data. OWL is the representative ontology language suggested by W3C. An efficient retrieval of OWL data requires a well-constructed storage schema. In this paper, we propose a storage schema construction technique which supports more efficient query processing. A retrieval technique corresponding to the proposed storage schema is also introduced. OWL data includes inheritance information of classes and properties. When OWL data is extracted, hierarchy information should be considered. For this reason, an additional XML document is created to preserve hierarchy information and stored in an XML database system. An existing numbering scheme is utilized to extract ancestor/descendent relationships, and order information of nodes is added as attribute values of elements in an XML document. Thus, it is possible to retrieve subclasses and subproperties fast and easily. The improved query performance from experiments shows the effectiveness of the proposed storage schema construction and retrieval method.

Civil projects are associated with many uncertainties because they involve a long duration, many resources, a large area, and many supply chains. Therefore, the price of a civil project is not simply proportional to the quantity and unit price of the item but has a variable value, including uncertainty risk. This study investigates the influence of the uncertainty factors in the pre-bid clarification document on bid price formation during the project bidding phase. To this end, civil projects from the California Department of Transportation (Caltrans) were used as research data. This study randomly selected fifty sample data from each of twelve counties from 2008-to 2020: six hundred. The authors observed that each project sample had 0 to n query cases due to uncertainty. Then, this study examined the project uncertainty cases and categorized them into the following four uncertainty factors: 'conflict' (UF1), 'impossibility' (UF2), 'lack' (UF3), and 'missing' (UF4). Under the extracting process, the cases are classified into four uncertainty factors. With the project not containing any uncertainty factors as a control group, the project containing these uncertainty factors was designated as an experimental group. After comparing the bidder's price, the experimental group's bid price was higher than the control group's. This result suggests that uncertainty factors in bid documents induce bidders to set a high bid price as a defense against uncertainty.

As the concept of sustainability becomes more and more popular, a large amount of literature have been recorded recently on intelligent green building and smart city (IGB&SC). It is therefore needed to systematically analyse the existing knowledge structure as well as the future new development of this domain through the identification of the thematic trends, landmark articles, typical keywords together with co-operative researchers. In this paper, Citespace software package is applied to analyse the citation networks and other relevant data of the past eleven years (from 2006 to 2016) collected from Web of Science (WOS). Through this, a series of professional document analysis are conducted, including the production of core authors, the influence made by the most cited authors, keywords extraction and timezone analysis, hot topics of research, highly cited papers and trends with regard to co-citation analysis, etc. As a result, the development track of the IGB&SC domains is revealed and visualized and the following results reached: (i) in the research area of IGB&SC, the most productive researcher is Winters JV and Caragliu A is most influential on the other hand; (ii) different focuses of IGB&SC research have been emerged continually from 2006 to 2016 e.g. smart growth, sustainability, smart city, big data, etc.; (iii) Hollands's work is identified with the most citations and the emerging trends, as revealed from the bursts analysis in document co-citations, can be concluded as smart growth, the assessment of intelligent green building and smart city.

Built-in wardrobe is constructing after ordering and making, because built-in wardrobe's size is fixed as housing measurement. It is hard to speak built-in wardrobe components of construction in these ways, and application of an MC (Modular Coordination) design system is meaningless too. And above all, measurement before construction isn't to expect standardization, and to increase custom-made furniture. So I suggest the standardization of built-in wardrobe utilizing standard last finish and reference plane in order to prevent an evil influence of built-in wardrobe's construction. And we utilized a reference plane, and we present construction document and design plan in order to solve these problems. The first stage, we investigate manufacture of a preferential domestic system kitchen and construction state, and we derive from a problem in viewpoints of standardization for this. And we analyze an effect got by application of the assembly basis aspect that we presented, and we can raise efficiency of standardization of housing and construction industry, and we light ultimately up. I will apply a standardization plan as above, and define that this assures a standardization of components and an economic effect.
