Historical data from comparable projects can serve as benchmarking data for an ongoing project's planning during the project scoping phase. As project owners typically store substantial amounts of data generated throughout project life cycles in digitized databases, they can capture appropriate data to support various project planning activities by accessing digital databases. One of the most important work tasks in this process is identifying one or more past projects comparable to a new project. The uniqueness and complexity of construction projects along with unorganized data, impede the reliable identification of comparable past projects. A project scope document provides the preliminary overview of a project in terms of the extent of the project and project requirements. However, narratives and free-formatted descriptions of project scopes are a significant and time-consuming barrier if a human needs to review them and determine similar projects. This study proposes an Artificial Intelligence-driven model for analyzing project scope descriptions and evaluating project similarity using natural language processing (NLP) techniques. The proposed algorithm can intelligently a) extract major work activities from unstructured descriptions held in a database and b) quantify similarities by considering the semantic features of texts representing work activities. The proposed model enhances historical comparable project identification by systematically analyzing project scopes.

본 논문에서는 농수산물을 저장 관리를 목적으로 유비쿼터스 센서로부터 획득한 상황 정보를 활용하여 창고관리 정보를 공유하고 분산시키기 위한 온톨로지 기반 상황인지 시스템 모델링에 관하여 제안한다. 오늘날 우리 생활속에 유비쿼터스 기술이 확산됨에 따라 정보에 대한 중요성은 더욱 증가하고 있다. 뿐만 아니라, 하나의 도메인에 대한 온톨로지의 중요성도 또한 증가하고 있다. 그러므로 본 논문에서는 상황정보 상태에 대한 정보를 획득하기 위해서 무선 센서로부터 획득한 정보가 온톨로지에서 활용될 수 있도록 온톨로지 기반의 농수산물 웨어하우스 모델을 설계한다. 이를 통해 농수산물용 창고 관리가 상황점보에 따라 사용자, 장치들 및 서비스사이에 의미가 상호 연동할 수 있는, 의미정보 구조에 대한 공통의 이해를 공유할 수 있도록 온톨로지로 표현된 결과를 보인다.

The food tech market, which uses artificial intelligence robots for the restaurant industry, is gradually expanding. Among them, the robot barista, a representative food tech case for the restaurant industry, is characterized by increasing the efficiency of operators and providing things for visitors to see and enjoy through a 24-hour unmanned operation. This research was conducted through text mining analysis to examine trends related to robot baristas in the restaurant industry. The research results are as follows. First, keywords such as coffee, cafe, certification, ordering, taste, interest, people, robot cafe, coffee barista expert, free, course, unmanned, and wine sommelier were highly frequent. Second, time, variety, possibility, people, process, operation, service, and thought showed high closeness centrality. Third, as a result of CONCOR analysis, a total of 5 keyword clusters with high relevance to the restaurant industry were formed. In order to activate robot barista in the future, it is necessary to pay more attention to functional development that can strengthen its functions and features, as well as online promotion through various events and SNS in the robot barista cafe.

Online product reviews are a vital source for companies in that they contain consumers' opinions of products. The earlier methods of opinion mining, which involve drawing semantic information from text, have been mostly applied in one dimension. This is not sufficient in itself to elicit reviewers' comprehensive views on products. In this paper, we propose a novel approach in opinion mining by projecting online consumers' reviews in a multidimensional framework to improve review interpretation of products. First of all, we set up a new framework consisting of six dimensions based on a marketing management theory. To calculate the distances of review sentences and each dimension, we embed words in reviews utilizing Google's pre-trained word2vector model. We classified each sentence of the reviews into the respective dimensions of our new framework. After the classification, we measured the sentiment degrees for each sentence. The results were plotted using a radar graph in which the axes are the dimensions of the framework. We tested the strategy on Amazon product reviews of the iPhone and Galaxy smartphone series with a total of around 21,000 sentences. The results showed that the radar graphs visually reflected several issues associated with the products. The proposed method is not for specific product categories. It can be generally applied for opinion mining on reviews of any product category.

제한된 자원 하에서 멀티미디어 컨텐츠를 이용하기 위해서는 XML로 표현되는 MPEG-7 문서의 효율적인 관리 방법이 필요하다. 이 때 XML 문서 클러스터링 방법들을 이용할 수 있겠으나 보다 효율성을 높이기 위해 MPEG-7 문서의 특성을 반영한 새로운 방법이 요구된다. 본 논문에서는 MPEG-7 문서를 효율적으로 관리하기 위해 MPEG-7 문서의 엘리먼트들 사이에 나타나는 의미 관련성을 이용해 저장할 수 있는 새로운 클러스터링 방법을 제안하고, 이를 기존 방법들과 비교하였다.

In this paper, a user-friendly mobile photo album system and albuming functions to support it are introduced. Stand-alone implementation in a mobile device is considered. The main idea of user-friendly photo browsing for albuming functions is to enable users to organize and browse their photos along semantically meaningful axes of events, personal identities, and categories. Experimental results demonstrate that the proposed method would be sufficiently useful and efficient for browsing personal photos in mobile environment.

The main purpose of this study was to investigate preschoolers understanding whether thinking influences emotion with cognitive cueing. The subjects were 75 preschoolers of the J, Y, & K kindergartens located in Taegu. They were 4-(12 boys and 13 girls), 5-(12 boy and 13 girls), and 6-years(13 boys and 12 girls) old. The instruments were 4 stories and 11 pictures per a story used in Lagattuta, Wellman & Flavell(1997). The responses given from preschoolers were classified in terms of cognitive cueing response. The major results showed that an initial understanding of cognitive cueing in some preschoolers revealed the evidence of significantly developmental changes during the preschool years. Cognitive cueing responses were significantly different according to thinking prompt which is the question to help preschoolers explanations. This result suggested that the instruments of measurement for preschoolers should be improved as possible as they can understand.

This study was to analyze amenity of the port landscapes for North port, South port, and Gamcheon port in Busan. Amenity related variables came from Semantic Differential(SD) method and then were conducted by the factor analysis. Multiple regression was done for the relationship between the amenity and factors. The result found 3 factors, including dynamics, stability, and familarity. Much importance was placed on dynamics among them. Therefore, building port landscapes and their image attracting tourists should consider dynamics in terms of port landscape plan and tourist attraction development for amenity quality management.

The purpose of this paper is to propose a securely personalized context-aware cooperative query that supports a multi-level data abstraction hierarchy and conceptual distance metric among data values, while considering privacy concerns around user context awareness. The conceptual distance expresses a semantic similarity among data values with a quantitative measure, and thus the conceptual distance enables query results to be ranked. To show the feasibility of the methodology proposed in this paper we have implemented a prototype system in the area of site search in a large-scale shopping mall.
