Nowadays, access to information requires managing multimedia databases effectively, and so, multi-modal retrieval techniques (particularly images retrieval) have become an active research direction. In the past few years, a lot of content-based image retrieval (CBIR) systems have been developed. However, despite the progress achieved in the CBIR, the retrieval accuracy of current systems is still limited and often worse than only textual information retrieval systems. In this paper, we propose to combine content-based and text-based approaches to multi-modal retrieval in order to achieve better results and overcome the lacks of these techniques when they are taken separately. For this purpose, we use a medical collection that includes both images and non-structured text. We retrieve images from a CBIR system and textual information through a traditional information retrieval system. Then, we combine the results obtained from both systems in order to improve the final performance. Furthermore, we use the information gain (IG) measure to reduce and improve the textual information included in multi-modal information retrieval systems. We have carried out several experiments that combine this reduction technique with a visual and textual information merger. The results obtained are highly promising and show the profit obtained when textual information is managed to improve conventional multi-modal systems. 相似文献

"信息孤岛"现象的出现,致使医疗卫生资源及患者信息的整合程度低,不能共享。意味着大量信息资源的浪费,直接造成医疗成本的增加。卫生部最新制定的我国卫生信息化发展的"十二五"规划中,也明确提出加强信息标准建设,清除信息孤岛等问题。要想落实新医改政策,就需要分析原因、从根本上消除信息孤岛现象。 相似文献

The Multilevel Information System (MLIS), extension of typical Information Retrieval System towards more complete data processing, is discussed. MLIS integrates functions typical for data base management systems and retrieval-oriented systems. Several levels of data accessing are provided, each level developed for a different class of users. End-user level is based on simple query language, trained user level on a relational model, and application programmer level on a Data Manipulation Language nested in high level programming language. The last two levels are discussed in detail. 相似文献

In the past, Geographical Information Systems (GIS) have been used and developed by small groups of professionals within organizations, for example, town planners within local authorities. Champions from such enthusiastic groups have made enormous contributions to the development of working GIS in practice. However, GIS implementations that are ad hoc developments primarily designed to improve the operations of the organization are potentially underutilizing the benefits of GIS. In business applications GIS must be seen as another potential tool. Managers need to see GIS among a range of management support tools, in a way that other information systems might be viewed. The integration of GIS into corporate information systems is vital for gaining the maximum benefit from the information resources of the organization. The paper explores issues such as: How can GIS be integrated into the information strategy? What are the benefits of such an integration? The paper puts forward a framework for considering GIS within the corporate information strategy. 相似文献

Abstract The worldwide use of computers, telecommunications, and other information technologies is giving rise to the formation of new communities called “information communities.” In the United States, for example, more people are employed as information givers, takers, or orchestrators in these communities than in any other occupation class. With so many social resources going into the conduct of these communities, it is essential that they are designed to be ethical. This requires that we identify the parties involved in each community, that we be empathetic and sympathetic to their needs and that we follow Kant's dictum by always treating them as “ends in themselves.” 相似文献

Finding useful health information should be the highest priority when identifying health information. Predicting information usefulness will significantly improve the effectiveness and efficiency of health information identification, which plays a vital role in fighting against misinformation. Modal behaviors, such as gesture and gaze, are promising indicators of usefulness since they deliver a reliable, thorough, natural, and direct process of user cognitive processing. Therefore, this study aimed to use gesture and gaze behaviors to predict whether information is useful for health information identification. Twenty-four college students were recruited to freely search for information using a smartphone to identify the truthfulness of four propositions (two were true and two were false) about public health epidemics. The participants' gesture behavior, gaze behavior, and information usefulness as perceived by themselves were collected. Based on user cognition, the process of information usefulness judgment was placed into two phases: skimming and reading. Thirty-one features derived from modal behaviors in each phase were extracted. Feature optimization based on the Mann-Whitney U test and random forest was performed. Five common algorithms were used to construct information usefulness prediction models, and these models were compared by the F1_score. Finally, dwell time and gaze entropy in the reading phase were the most important gesture and gaze features respectively. BP neural network was selected to build a unimodal model based on gesture, and gradient boosting decision tree was selected to build a unimodal model based on gaze and a multimodal model combining both. These models all achieved F1_score above 77% and were applicable to different scenarios in health information identification. The model based on gesture could satisfy strong technology or legal constrains, the model based on gaze was ideal for AR, MR or metaverse applications, and the model combining both offered an alternative for multimodal human-computer interaction. 相似文献

Individuals seek information for informed decision-making, and they consult a variety of information sources nowadays. However, studies show that information from multiple sources can lead to information overload, which then creates negative psychological and behavioral responses. Drawing on the Stimulus-Organism-Response (S-O-R) framework, we propose a model to understand the effect of information seeking, information sources, and information overload (Stimuli) on information anxiety (psychological organism), and consequent behavioral response, information avoidance during the global health crisis (COVID-19). The proposed model was tested using partial least square structural equation modeling (PLS-SEM) for which data were collected from 321 Finnish adults using an online survey. People found to seek information from traditional sources such as mass media, print media, and online sources such as official websites and websites of newspapers and forums. Social media and personal networks were not the preferred sources. On the other hand, among different information sources, social media exposure has a significant relationship with information overload as well as information anxiety. Besides, information overload also predicted information anxiety, which further resulted in information avoidance. 相似文献

Abstract Public information systems are described and contrasted to commercial information systems. Three generations of public information systems are identified in close correspondence to the three generations of commercial information systems. Each generation is characterized in terms of the technology and the infrastructure required, the problems it alleviates, and the impact on society. Examples are given both of the traditional and the automated public information systems and the social problems they attack. 相似文献
