Ranking thousands of web documents so that they are matched in response to a user query is really a challenging task. For this purpose, search engines use different ranking mechanisms on apparently related resultant web documents to decide the order in which documents should be displayed. Existing ranking mechanisms decide on the order of a web page based on the amount and popularity of the links pointed to and emerging from it. Sometime search engines result in placing less relevant documents in the top positions in response to a user query. There is a strong need to improve the ranking strategy. In this paper, a novel ranking mechanism is being proposed to rank the web documents that consider both the HTML structure of a page and the contextual senses of keywords that are present within it and its back-links. The approach has been tested on data sets of URLs and on their back-links in relation to different topics. The experimental result shows that the overall search results, in response to user queries, are improved. The ordering of the links that have been obtained is compared with the ordering that has been done by using the page rank score. The results obtained thereafter shows that the proposed mechanism contextually puts more related web pages in the top order, as compared to the page rank score.

BACKGROUND: Global longitudinal strain (GLS) is an accurate and reproducible parameter of left ventricular (LV) systolic function which has shown meaningful prognostic value. Fast, user-friendly, and accurate tools are required for its widespread implementation. We aim to compare a novel web-based tool with two established algorithms for strain analysis and test its reproducibility. METHODS: Thirty echocardiographic datasets with focused LV acquisitions were analyzed using three different semi-automated endocardial GLS algorithms by two readers. Analyses were repeated by one reader for the purpose of intra-observer variability. CAAS Qardia (Pie Medical Imaging) was compared with 2DCPA and AutoLV (TomTec). RESULTS: Mean GLS values were -15.0 ± 3.5% from Qardia, -15.3 ± 4.0% from 2DCPA, and -15.2 ± 3.8% from AutoLV. Mean GLS between Qardia and 2DCPA were not statistically different (p = 0.359), with a bias of -0.3%, limits of agreement (LOA) of 3.7%, and an intraclass correlation coefficient (ICC) of 0.88. Mean GLS between Qardia and AutoLV were not statistically different (p = 0.637), with a bias of -0.2%, LOA of 3.4%, and an ICC of 0.89. The coefficient of variation (CV) for intra-observer variability was 4.4% for Qardia, 8.4% 2DCPA, and 7.7% AutoLV. The CV for inter-observer variability was 4.5%, 8.1%, and 8.0%, respectively. CONCLUSIONS: In echocardiographic datasets of good image quality analyzed at an independent core laboratory using a standardized annotation method, a novel web-based tool for GLS analysis showed consistent results when compared with two algorithms of an established platform. Moreover, inter- and intra-observer reproducibility results were excellent.

Creativity is a long cherished and widely studied aspect of human behavior that allows us to re-invent the familiar, and to imagine the new. Computational creativity (CC) is a newly burgeoning area of creativity research that brings together academics and practitioners from diverse disciplines, genres and modalities, to explore the potential of computers to be autonomously creative, or to collaborate as co-creators with people. We describe here an architecture for creative Web services that will act as a force magnifier for CC, both for academic research, and for the effective deployment of real CC applications in industry. For researchers, this service-oriented architecture supports the pooling of technologies in a robust interoperable framework, in which CC models are conceived, developed and migrated from lab settings to an industrial strength platform. Industry developers, for their part, will be able to exploit novel results of CC research in a robust, low-risk form, without having to re-implement algorithms from a quickly moving field. We illustrate the architecture with the first of a growing set of creative Web services that provide robust figurative language processing on demand.

In this paper, we propose a prototype of the SpeechWeb application using the information selection agent. We describe its design and implementation method and illustrated the processing results with the aid of some screenshots. Proposed SpeechWeb application presents the associated contents to the user by the aid of dynamic voice-anchors. These contents are presented using the apriori algorithm, which is one of data mining techniques. The application is better than the existing user-initiative structure from the viewpoint of making the user's interesting induction. Moreover, we believe that our proposed application is effective in information retrieval through wired and wireless telephone networks.

This paper proposes a novel Web Services enhancement method, which enhances XML based e-commerce and Web Services securely and efficiently. Recently, the ratio of XML Denial of Services (XDOS) is increased significantly However, XML data is visible only at the target application site or the application layer. Thus, an efficient and secure mechanism handling XML data on the network layer to provide fast performance on the server and protect XDOS at network level is strongly required basic component. This paper presents many issues and gives useful results from the various experiments to support an implemented XAN platform.

A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.

Animated images formats such as WebP are highly portable graphics formats that are being used everywhere on the Internet. Despite their small sizes and duration, WebP image previews the video without watching the entire content with minimum bandwidth. This paper proposed a novel method to generate personalized WebP images in the client side using its computation resources. The proposed system automatically extracts the WebP image from climax point using music analysis. Based on user interest, the system predicts the genre using Convolutional Neural Network (CNN). The proposed method can easily integrate with streaming platforms such as YouTube, Netflix, Hulu, and others.

With the rapid development of deep learning and artificial intelligence, generative models have achieved remarkable success in the field of image generation. By combining the stable diffusion method with Web UI technology, a novel solution is provided for the application of AI painting generation. The application prospects of this technology are very broad and can be applied to multiple fields, such as digital art, concept design, game development, and more. Furthermore, the platform based on Web UI facilitates user operations, making the technology more easily applicable to practical scenarios. This paper introduces the basic principles of Stable Diffusion Web UI technology. This technique utilizes the stability of diffusion processes to improve the output quality of generative models. By gradually introducing noise during the generation process, the model can generate smoother and more coherent images. Additionally, the analysis of different model types and applications within Stable Diffusion Web UI provides creators with a more comprehensive understanding, offering valuable insights for fields such as artistic creation and design.

이 연구는 익숙한 장르 문법이나 코드 활용이 자유로운 대중문화콘텐츠의 특성이 반영된 웹소설, 특히 로맨스판타지 장르의 '책빙의물'의 특성에 주목하였다. 주인공이 자신이 현실세계에서 읽은 작품 속으로 들어가는 상상력은 웹소설의 기존 장르문법을 재해석한 것으로, 이 모티프를 연구하는 것은 장르 내 상호텍스트성 검토에 유의미하다. 로맨스 판타지 장르에서 책빙의물은 일반 판타지 장르(퓨전판타지, 현대판타지 등)와 차이점을 보이는데, 장르의 젠더적 특성을 드러내는 데도 이 연구의 목적을 들 수 있다. 이 연구는 책빙의물이 기존 서사에 대한 상호텍스트적 해석에서 탄생되었으며, 따라서 차원이동, 회귀, 대체역사물과 친연성을 갖는다고 보았으며, 팬픽션의 글쓰기 규범을 참고했다고 보았다. 이를 통해 앞으로 기존 서사의 재조합과 장르 간 간섭이 지속될 것을 예측할 수 있었다. 다음으로 로맨스판타지 장르에서의 책빙의물은 주변인이 주인공이 되어 서사를 전복함에도 상당히 보수적이고 자기계발적인 논리를 드러낸다고 보았다. 등장인물들은 현실세계의 미래지식을 활용해 파멸이 예언된 생존세계에서 투쟁해야 한다. 윤리적이고 자조(self-help)적인 주체의 등장은 흥미롭지만, 한편으로 로맨스가 인물들의 생존과 성취의 한 방식이라는 점에서 보수성을 살펴볼 수 있었다. 이 연구는 로맨스판타지 장르에서 상당히 빠르게 시작된 책빙의물의 특성을 검토하고 그 등장배경과 특성을 검토했다는 점에서 연구의의를 갖는다. 물리적인 작품 수합에 한계가 있고, 플랫폼이 한정되었다는 한계가 있었다. 위의 한계는 추후 등장하는 작품들을 좀 더 검토하며 보완하고자 한다.
