基于信息项和用户群的信息推荐机制   总被引:2,自引:1,他引:2  
如何准确高效地提供给用户需要的信息,是信息推荐研究的核心。本文提出了一种推荐机制———基于信息项和用户群的信息推荐机制,它综合考虑了用户自身和其邻居用户对推荐的影响。在计算用户自身对推荐的影响时,采用了基于信息项的方法。在计算邻居用户对推荐的影响时,首先寻找目标用户的邻居用户,形成一个用户群,根据用户群中其他用户对目标项目的推荐产生目标用户对目标项目的推荐。在MovieLens上的实验证明,本文提出的这种算法在预测精度上较传统的推荐算法有很大的提高。  相似文献

Social media activism has become very relevant for many student activist groups. How can political use of social media be motivated? The concept of Social Media Political Efficacy was proposed to resolve inconsistencies in prior theories of social media activism. A survey (n = 222) of members of 3 student activist groups showed that social media political efficacy was positively related to successful experiences using social media for activism. The relationship between social media political efficacy and social media activism was stronger than that between the concept of political efficacy employed in prior research and social media activism. Theory and social media activism implications are discussed.  相似文献

��[Purpose/significance] The development of digital humanities has aroused widespread concern in the field of social sciences and humanities, by using convenient and efficient computing technology to extract potential information from massive data resources and unstructured text, and present it to users in a more intuitive and clear way.[Method/process] This paper took the war described in Zuo Zhuan as the research object, and extracted the strategic offensive sides and strategic defenders of each war from the war sentences. From the perspective of digital humanities, it explored the feasibility of using social network analysis methods to describe the changes of the war pattern in Spring and Autumn Period. On this basis, the vassal states in the Spring and Autumn Period were divided into different groups according to the relationship between war cooperation and war confrontation. The main groups and the core vassal states were analyzed and discussed one by one. In addition, the war in Zuo Zhuan was dynamically displayed in using 3 techniques:html, css and E-Charts.[Result/conclusion] We provided a method for extracting war information from the unstructured Zuo Zhuan texts during the Spring and Autumn Period and organized it into quantifiable data. It proved that it was feasible to show the relationship between the vassal states during the Spring and Autumn Period from the perspective of war, and also showed the feasibility and great potential of digital humanities technology in the research of humanistic history.  相似文献

Many critics have chided daytime television talk shows because of deviant behavior that they highlight. This study examined if exposure to daytime television talk shows cultivated negative attitudes and perceptions of interpersonal relationships in the U.S. among international and U.S. students. The hypothesis that international students would demonstrate more of a cultivation effect than U.S. students was tested using three dependent measures: (1) estimates of the frequency of certain inappropriate behaviors in the U.S., (2) attitudes about interpersonal relationships among certain primary groups in the U.S., and (3) perceptions of certain interpersonal relationships among primary groups in the U.S. The hypoth-sis received support on all three measures.  相似文献

This study investigated whether measures of error type, frequency, and sequencing contribute to understanding how different types of domain knowledge influence human performance when using information systems. Micro-level analyses of errors were conducted to compare the performance of two groups using a geographical information system (GIS). Error types, error frequency, error sequencing, and task completion were measured and compared for the two groups. The two groups were similar in frequency of type of errors; both committed terminological and trial errors more frequently than the other 10 types. Error patterns or sequences were likewise similar, and domain of expertise did not affect task completion time. The group with domain knowledge in computer science showed a somewhat greater tendency to commit certain knowledge-based errors (KBEs), indicating an association between knowledge-based errors and procedural knowledge. The group with domain knowledge in geography committed certain rule-based errors (RBEs) more often, indicating an association between rule-based errors and declarative knowledge. Therefore, error type does hold promise as a measure of the relationship between domain knowledge type and human performance using information systems.  相似文献

Background

Caregivers of children may rely on internet sources, health care providers, peers or family for health information.

Objective

To examine the impact of sociodemographic factors on the use of the internet for health information by caregivers of children, and the impact on self-efficacy, effort and frustration.

Methods

Using data from the 2019 Health Information National Trends Survey, the effects of information source on self-efficacy, effort and frustration was examined using the complex samples module of SPSS.

Results

The internet was the most common source of health information for caregivers of children (n = 247), with high confidence, low frustration and effort reported. Younger, higher educated and higher income caregivers were significantly more likely to use the internet for health information. Information from Health Care Providers (HCPs) was associated with greater confidence, and information from peers associated with lesser effort and frustration. No significant effects on self-efficacy, effort or frustration for online health information was noted compared to other sources.

Conclusions

Efforts to reduce barriers to online health information may be required for some groups of caregivers, and health care providers may have a role to play in this.  相似文献
