    Abstract
    Large image collections on the Web need to be organized for effective retrieval. Metadata has a key role in image retrieval but rely on professionally assigned tags which is not a viable option. Current content-based image retrieval systems have not demonstrated sufficient utility on large-scale image sources on the web, and are usually used as a supplement to existing text-based image retrieval systems. We present two social tagging alternatives in the form of photo-sharing networks and image labeling games. Here we analyze these applications to evaluate their usefulness from the semantic point of view, investigating the management of social tagging for indexing. The findings of the study have shown that social tagging can generate a sizeable number of tags that can be classified as in terpretive for an image, and that tagging behaviour has a manageable and adjustable nature depending on tagging guidelines.

    Abstract
    The motivation for this work has been to provide relevant information to the right situation for mobile phone users. We have iteratively developed applications for travellers and tourists to provide a general travel guide with local tourist information. This used a combination of wireless tag technology and information from content service providers. The paper presents our evaluation methodology and how we used it to develop the applications. The methodology is user centred, iterative, and progressive. It combines information retrieval (IR) evaluation methods with human-computer interaction (HCI) development techniques. Two groups of three user studies and a large survey were conducted in context with the studies scaling up to 238 participants and 438 user survey responses. The participants tested the applications in context, including the IR functions. They also filled in a pre and post questionnaire immediately before and after the system use. Some participants were additionally interviewed.

    Abstract
    Creative professionals in advertising, marketing, design and journalism search for images to visually represent a concept for their project. The main purpose of this paper is to present search facets derived from an analysis of documents known as briefs, which are widely used in creative industries as requirement documents describing information needs. The briefs specify the type of image required, such as the content and context of use for the image and represent the topic from which the searcher builds an image query. We take three main sources-user image search behaviour, briefs, and image search engine search facets-to examine the search facets for image searching in order to examine the following research question-are search facet schemes for image search engines sufficient for user needs, or is revision needed? We found that there are three main classes of user search facet, which include business, contextual and image related information. The key argument in the paper is that the facet "keyword/tag" is ambiguous and does not support user needs for more generic descriptions to broaden search or specific descriptions to narrow their search-we suggest that a more detailed search facet scheme would be appropriate.
