본 논문에서는 웹 접근성을 고려한 유저 인터페이스 효과를 jQuery로 구현하는 방법은 제안하였다. jQuery는 세계에서 가장 많이 사용하고 확장하기 편한 자바스크립트 라이브러리이다. jQuery는 DOM(Document Object Model)과 이벤트, Ajax의 제어에 적합하지만 고급 효과를 나타내기에는 부족한 부분이 있다. 이를 보완하고 UI(User Interface) 효과를 쉽게 적용할 수 있는 방법을 제시한다.

본 논문에서는 웹 응용에서 jQuery를 이용한 사용자 인터랙션을 설계하고 구현하는 방법들을 제안하였다. 스마트 기기의 컴퓨팅 능력이 향상되면서 웹 응용 기술이 보편화되고 다양화되었다. 이로 인해 주목받는 웹 기술로서 JavaScript가 있고, 세계적으로 가장 많이 쓰이는 JavaScript 프레임워크가 jQuery이다. jQuery의 기본 문법과 확장성 및 플러그인에 대해 간단히 서술하였다. 사용자 인터랙션과 애니메이션들을 분류하였고, 이를 구현할 수 있는 방법을 서술하였다.

Social Network Aggregators are used to maintain and manage manifold accounts over multiple online social networks. Displaying the Activity feed for each social network on a common dashboard has been the status quo of social aggregators for long, however retrieving the desired data from various social networks is a major concern. A user inputs the query desiring the specific outcome from the social networks. Since the intention of the query is solely known by user, therefore the output of the query may not be as per user's expectation unless the system considers 'user-centric' factors. Moreover, the quality of solution depends on these user-centric factors, the user inclination and the nature of the network as well. Thus, there is a need for a system that understands the user's intent serving structured objects. Further, choosing the best execution and optimal ranking functions is also a high priority concern. The current work finds motivation from the above requirements and thus proposes the design of a query processing system to retrieve information from social network that extracts user's intent from various social networks. For further improvements in the research the machine learning techniques are incorporated such as Latent Dirichlet Algorithm (LDA) and Ranking Algorithm to improve the query results and fetch the information using data mining techniques.The proposed framework uniquely contributes a user-centric query retrieval model based on natural language and it is worth mentioning that the proposed framework is efficient when compared on temporal metrics. The proposed Query Processing System to Retrieve Information from Social Network (QPSSN) will increase the discoverability of the user, helps the businesses to collaboratively execute promotions, determine new networks and people. It is an innovative approach to investigate the new aspects of social network. The proposed model offers a significant breakthrough scoring up to precision and recall respectively.

Recently various of information suppliers provide information via WWW so the necessary of search engine grows larger. However the efficiency of most search engines is low comparatively because of using simple pattern match technique between user's query and web document. And a manifest contents of query for special expert field so much worse A specialized search engine returns the specialized information depend on each user's search goal. It is trend to develop specialized search engines in many countries. For example, in America, there are a site that searches only the recently updated headline news and the federal law and the government and and so on. However, most such engines don't satisfy the user's needs. This paper proposes the specialized search engine for ocean information that uses user's query related with ocean and search engine uses the association rules in web data mining. So specialized search engine for ocean provides more information related to ocean because of raising recall about user's query

대부분의 상업용 정보검색 시스템은 사용자의 질의 형태로 불리언 질의를 채용했다. 불리언 질의는 빠른 검색을 필요로 하는 검색엔진에는 유용할지라도 불리언 연산자로 사용자의 요구를 정확하게 표현하기는 어렵다. 따라서 사용자에게 편리한 자연어 질의를 이용하는 검색 엔진에 대한 연구가 있어왔다 문서를 검색하기 위해서 사용자는 자신의 요구를 정확하게 표현해야 하며 사용자의 요구도 적절해야 한다. 따라서 본 논문에서는 자연어를 이용한 대화형 질의 처리 에이전트를 제안한다. 이 에이전트는 사용자와 점진적인 대화를 통해 사용자의 요구를 정확하게 표현한다. 사용자가 자연어 질의를 입력하면 에이전트는 질의를 분석하고 적절한 키워드를 추출하여 불리언 질의어를 생성한다. 추출된 키워드가 동의어이거나 다의어이면 사용자와 대화를 통해서 키워드를 한정하거나 확장한다. 이렇게 함으로써 사용자의 요구를 보다 구체적으로 표현하여 시스템의 성능을 향상시킨다. 따라서 본 시스템은 정보검색에서 정확률을 향상시킬 수 있다.

In For the past few years, query log data has been collected to find user's behavior in using the site. Many researches have studied on the usage of query logs to extract user's preference, recommend personalization, improve caching and pre-fetching of Web objects, build better adaptive user interfaces, and also to improve Web search for a search engine application. A query log contain data such as the client's IP address, time and date of request, the resources or page requested, status of request HTTP method used and the type of browser and operating system. A query log can offer valuable insight into web site usage. A proper compilation and interpretation of query log can provide a baseline of statistics that indicate the usage levels of website and can be used as tool to assist decision making in management activities. In this paper we want to discuss on the tasks performed of query logs in pre-processing of web usage mining. We will use query logs from an online newspaper company. The query logs will undergo pre-processing stage, in which the clickstream data is cleaned and partitioned into a set of user interactions which will represent the activities of each user during their visits to the site. The query logs will undergo essential task in pre-processing which are data cleaning and user identification.

Although knowledge discovery is increasingly important in databases, the discovered knowledge sets may not be effectively used for application domains. It is partly because knowledge discovery does not take user's interests into account, and too many knowledge sets are discovered to handle efficiently. We believe that user's interests are conveyed by a query and if a nested query is concerned it may include a user's thought process. This paper describes a novel concept for discovering knowledge sets based on query processing. Knowledge discovery process is performed by: extracting features from databases, spanning features to generate range features, and constituting a knowledge set. The contributions of this paper include the following: (1) not only simple queries but also nested queries are considered to discover knowledge sets regarding user's interests and user's thought process, (2) not only positive examples (answer to a query) but also negative examples are considered to discover knowledge sets regarding database abstraction and database exceptions, and (3) finally, the discovered knowledge sets are quantified.

최근 논리적으로 표현된 지식 베이스를 사용하는 키워드 기반 검색에서 보다 더 정확한 결과를 제공하기 위해 시맨틱 검색 방법에 대한 연구가 진행되고 있다. 대부분의 사용자는 정형화된 질의어와 스키마를 사용하는 것 보다 사용자 키워드의 의미를 해석해서 사용한다. 본 논문에서는 시맨틱 검색을 위한 사용자 질의 확장을 제안한다. 제안 시스템에서는 지식 베이스와 연관 검색어를 활용한 사용자 질의 확장 콤포넌트와 사용자 질의 해석 결과를 조정하기 위한 콤포넌트를 제공한다. 마지막으로 논문에서 제안한 사용자 질의 의미 해석 기법의 검증을 위해 프로토타입 시스템의 실험 결과를 설명한다.

As diverse researches are working about location acquisition, storing method, data modeling and query processing of moving objects, the moving object database systems, which can gain, store and manage location information and query processing, are tuning up. As the mobile device is moving but have constraints, the convenience user interface for spatio-temporal query and viewing query result needs. In this paper, we designed user Interface for spatio-temporal query related moving objects, viewing query result, tracing current and past location of those and monitoring. And we designed system for implementation of these interfaces.
