Objectives : The purpose of this study was to confirm the consumption trends of Korean medicine for health food consumption of consumers by using the Naver DataLab Shopping Insight service. Methods : In this study, the search data for the category of Korean herbal ingredients in the health food field of Naver Datalab shopping insight site was collected and sorted in order of frequency from August 1st, 2017 to June 22nd, 2022. The frequently searched keywords were organized based on the inclusion of Korean Pharmacopoeia (KP), Korean Herbal Pharmacopoeia (KHP), and Food Code. Results : 67,804 keywords were collected, and the most frequent keywords appearing for more than 200 days among the top 500 were 827 (1.184%). Among the frequent keywords, there were 149 keywords related to traditional medicine names included in the KP and KHP, and five prescriptions were included. 60 keywords were not included in the KP and KHP, and the keyword with the highest search frequency was "kujibbongnamu" (Maclura tricuspidata). Conclusions : The findings of this study provide information on the consumer's interest in traditional korean medicine (TKM) and natural products (NP), and can be used as a basis for understanding the demand for TKM and NP in the online shopping market.

In this paper, we propose a keyword query processing technique based on semantic relationships for OWL data. The proposed keyword query processing technique can improve user's search satisfaction by performing two types of associative search. The first associative search uses information inferred by the relationships between classes or properties during keyword query processing. And it supports to search all information resources that are either directly or indirectly related with query keywords by semantic relationships between information resources. The second associative search returns not only information resources related with query keywords but also values of properties of them. We design a storage schema and index structures to support the proposed technique. And we propose evaluation functions to rank retrieved information resources according to three criteria. Finally, we evaluate the validity and accuracy of the proposed technique through experiments. The proposed technique can be utilized in a variety of fields, such as paper retrieval and multimedia retrieval.

Introduction. In this study, purpose is to analize the types of golf tourism, inbound or outbound, by using big data and see how movement of industry is being changed and what changes have been made during and after Covid-19 in golf industry. Method Using Textom, a big data analysis tool, "golf tourism" and "Covid-19" were selected as keywords, and search frequency information of Naver and Daum was collected for a year from 1 st January, 2023 to 31st December, 2023, and data preprocessing was conducted based on this. For the suitability of the study and more accurate data, data not related to "golf tourism" was removed through the refining process, and similar keywords were grouped into the same keyword to perform analysis. As a result of the word refining process, top 36 keywords with the highest relevance and search frequency were selected and applied to this study. The top 36 keywords derived through word purification were subjected to TF-IDF analysis, visualization analysis using Ucinet6 and NetDraw programs, network analysis between keywords, and cluster analysis between each keyword through Concor analysis. Results By using big data analysis, it was found out option of oversea golf tourism is affecting on inbound golf travel. "Golf", "Tourism", "Vietnam", "Thailand" showed high frequencies, which proves that oversea golf tour is now the re-coming trends.

The Community Social Service Investment project started as a state subsidy project in 2007 and has grown very rapidly in quantitative terms in a short period of time. It is a bottom-up project that discovers the welfare needs of people and plans and provides services suitable for them. The purpose of this study is to analyze using big data to determine the social response to local community service investment projects. For this, data was collected and analyzed by crawling with a specific keyword of community service investment project on Google and Naver sites. As for the analysis contents, monthly search volume, related keywords, monthly search volume, search rate by age, and gender search rate were conducted. As a result, 10 items were found as related keywords in Google, and 3 items were found in Naver. The overall results of Google and Naver sites were slightly different, but they increased and decreased at almost the same time. Therefore, it can be seen that the community service investment project continues to attract users' interest.

질의 확장은 입력된 질의와 관련된 키워드를 사용자에게 제시하여 검색 활동에 도움을 주는 방법이다. 최근에는 사용자가 검색한 내용에서 군집화 방법을 이용하여 도메인을 찾고 키워드를 제시하는 연구가 많이 이루어졌다. 하지만 군집화 방법은 군집의 개수를 정해야하기 때문에 다양한 도메인을 나타내는데 적절하지 않다. 따라서 본 논문은 커뮤니티 인지 알고리즘으로 검색 문서에서 질의마다 다양한 수의 도메인을 찾고 키워드로 선택하여 제시하는 방법을 제안한다. 이를 위해 사용자가 검색한 결과 중 상위 30개 문서를 대상으로 단어를 추출하여 그래프 기반의 커뮤니티를 만들고, 각 커뮤니티에서 키워드를 추출하여 이를 질의 확장에 이용하였다. 본 논문에서 제안한 방법은 구글 검색 엔진과 검색된 문서의 tf-idf를 이용한 키워드 추천 방법과 비교하였다. 제안한 방법이 다른 비교 대상들에 비해 더 다양한 키워드를 추천할 수 있었다.

본 논문에서는 자료 조사를 위한 최적의 키워드 추출 및 검색 방법을 제안하였으며, 북한 건설 관련 동향 파악을 예시로 제안 방법을 검증하였다. 대표적인 국내 언론 플랫폼인 빅카인즈(BigKinds)를 활용하여 표본 기사를 선정하고 키워드를 추출하였다. 추출된 키워드는 워드 임베딩(Word Embedding)을 활용하여 벡터화하였으며, 이를 토대로 코사인 유사도(Cosine Similarity)를 통해 추출된 키워드 간의 유사도를 검사하였다. 또한 상위 빈도수 10개에 대한 키워드를 기준으로 유사도 0.5 이상인 키워드들을 군집화하였다. 각 군집들은 빅카인즈 검색 양식에 맞추어 군집 내부 키워드 간에는 'OR', 군집 간에는 'AND'로 형성하였다. 심층 분석 결과, 본래 목적에 맞는 유의미한 기사들이 추출되었음을 확인할 수 있었다. 기존의 분류체계 및 검색 양식을 변형시키지 않은 상태에서 사용자의 세부 목적을 충족시키는 자료 조사·분류가 가능하게 되었다는 점에서 의의를 갖는다.

웹은 사용자에게 제품이나 정보를 제공할 수 있는 가장 커다란 매체로 성장하였으며, 또한 사용자에게는 필요 이상의 정보를 얻게 해주고 있다. 웹은 다량의 관련 정보들을 여러 웹 페이지들을 통해 표현하고 있으며, 현재 검색엔진들은 키워드들에 관련된 단일 페이지들만을 리스트화하여 보여주고 있다. 근본적으로 이러한 방법들로는 관련된 정보를 가지고 있는 페이지들의 쌍 및 연관된 뭔 페이지들의 집합을 구조화하여 제공할 수 없다. 웹은 하나의 웹 페이지에 모든 관련 정보를 담는 범위를 넘어 관련된 정보 페이지들을 하이퍼링크로 서로 연결한 일련의 정보로 인식되고 있다. 따라서 본 논문에서는 새로운 링크 가중치 기반 검색 기법으로서 e-아크 메저에 관하여 제안하고자 하며, 이는 사용자가 입력한 키워드들과 관련된 페이지의 집합을 웹 사이트 안에서 찾아내는 연관 검색에 효과적이라는 것을 보이고, 실험을 통해 기존의 메저들 보다 그 효과성을 우월하다는 점을 입증하였다.

Text-based image retrieval is not only cumbersome as it requires the manual input of keywords by the user, but is also limited in the semantic approach of keywords. However, content-based image retrieval enables visual processing by a computer to solve the problems of text retrieval more fundamentally. Vision applications such as extraction and mapping of image characteristics, require the processing of a large amount of data in a mobile environment, rendering efficient power consumption difficult. Hence, an effective image retrieval method on mobile platforms is proposed herein. To provide the visual meaning of keywords to be inserted into images, the efficiency of image retrieval is improved by extracting keywords of exchangeable image file format metadata from images retrieved through a content-based similar image retrieval method and then adding automatic keywords to images captured on mobile devices. Additionally, users can manually add or modify keywords to the image metadata.

The Relational ranking method applies authority-based ranking in relational dataset that can be modeled as graphs considering also their tuples' values. Authority directions from tuples that contain the given keywords and transfer to their corresponding neighboring nodes in accordance with their values and semantic connections. From our previous work, ObjectRank extends to ValueRank that also takes into account the value of tuples in authority transfer flows. In a maked difference from ObjectRank, which only considers authority flows through relationships, it is only valid in the bibliographic databases e.g. DBLP dataset, ValueRank facilitates the estimation of importance for any databases, e.g. trading databases, etc. A relational keyword search paradigm Object Summary (denote as OS) is proposed recently, given a set of keywords, a group of Object Summaries as its query result. An OS is a multilevel-tree data structure, in which node (namely the tuple with keywords) is OS's root node, and the surrounding nodes are the summary of all data on the graph. But, some of these trees have a very large in total number of tuples, size-l OSs are the OS snippets, have also been investigated using ValueRank.We evaluated the real bibliographical dataset and Microsoft business databases to verify of our proposed approach.

이 논문은 사용자의 쿼리와 사용자의 행동양식을 바탕으로 상대네트워크를 구축함으로써 개인화된 논문검색 시스템을 모델링한 것이다. 제안하는 시스템은 사용자가 검색한 논문에서 키워드의 빈도수를 분석하여 개인적 상대네트워크를 구축하게 되는데, 이 네트워크는 다운로드, 열기, 삭제 등과 같은 사용자의 행동으로부터 키워드간 가중치를 조정을 함으로써 구축된다. 시스템의 성능평가를 위해 수원대학교에 있는 100명의 사용자들을 대상으로 실험한 결과, 기존의 검색엔진을 사용했을 때보다 성능이 우수하여 사용자 만족도가 높게 나타남을 알 수 있었다
