TL;DR: This article considers literature from many disciplines to describe a taxonomy of image content, from direct sensory elements to high-level abstractions, and identifies nine categories derived which will later be validated and used to direct the design of visual query interfaces for IDB systems.
Abstract: Image database (IDB) systems are at present often designed to test technology and the efficacy of retrieval algorithms, rather than being oriented towards delivering functionality to users. Research is necessary to design interfaces geared towards human usage of images. The starting point of this research needs to be consideration at a fundamental, user-centred level of how people perceive and interpret images. This article considers literature from many disciplines to describe a taxonomy of image content, from direct sensory elements to high-level abstractions. The nine categories derived will later be validated and used to direct the design of visual query interfaces for IDB systems.

TL;DR: In this paper, the authors describe an experimental investigation of two factors which are believed to influence users trust and willingness to engage in online commerce: reputation (a factor related to brand) and personalisation.
Abstract: This report describes an experimental investigation of two factors which are believed to influence users trust and willingness to engage in online commerce. The factors are: (a) reputation (a factor related to brand), and (b) personalisation. One hundred and seven users were logged on to a mock travel insurance website and asked to fill in insurance forms online, to make a decision as to whether or not they wanted to purchase insurance and then to answer a follow-up questionnaire. Behavioural and subjective measures of trust in the site were taken. Personalisation was shown to favourably influence user judgments about the site, although not to direcly influence trust.
