“…13 related to IFT also studies an information forager's linkfollowing behavior in a context where the forager has a fully formed goal and looks for a precise answer (e.g., Lawrance et al 2010, Olston andChi 2003). A resulting prescription is that search systems should facilitate an efficient search process centered at a defined need (e.g., Fang et al 2012). However, users' preferences may change as they encounter new information, and their selection of search cues reflects their dynamic goals.…”

Designing for Diagnosticity and Serendipity: An Investigation of Social Product-Search Mechanisms

Users are increasingly sharing their product interests and experiences with others on e-commerce websites. For example, users can "tag" products using their own words, and these "product tags" then serve as navigation cues for other users who want to search for products. Also, socially endorsed information contributors are sometimes highlighted on websites and serve as direct information sources. This study examines the effects of these two distinct social product search cues, product tags and socially endorsed people, on users' perceived diagnosticity and serendipity of their product search experience. While product tags support product navigation via a variety of product features tagged by the community, access to socially endorsed people enables users to browse diverse and high-quality alternatives favored by these individuals. We constructed an experimental website using real data from one of the largest social-network-based product-search websites in China to conduct an empirical study. The results of this study show that product tags help users to locate and evaluate relevant alternatives, thus enhancing the perceived diagnosticity of product search, whereas the integration of product tags and access to socially endorsed people enables users to conduct even more serendipitous searches. In addition, both perceived diagnosticity and perceived serendipity of a search experience positively affect users' decision satisfaction.

“…First, many of these sites consist of thousands of pages-in some cases, many thousands of pages-making whole site analysis of every site unrealistic. In addition, studies often analyze the homepage of sites [3], [5], [10], [29]- [32], since the homepage is the page many visitors enter by and are typically the most visited page on a site [3] and the page where most users start tasks [4].…”

“…Since the homepage is the most visited page of most websites [1] and the most common starting place for visitors to a site [4], the homepage is a practical focus of study in web design practice. Likewise, Fortune 500 company websites are often studied by researchers wishing to analyze web design trends [5]- [11].…”

Research problem: As a follow up to an earlier article, this study compares Fortune 500 website homepage design in 2013 with the results of a similar study in 2008, providing an updated overview of homepage design practice that reflects the many technological advances that have influenced web design during the intervening period. The findings are useful for those wanting to know the state of homepage design in 2013, whether as current practitioners or researchers. Research questions: (1) What are the current homepage design practices of Fortune 500 companies? (2) What are the current Web 2.0 technology practices of Fortune 500 companies? (3) What changes in homepage design have occurred for Fortune 500 companies? (4) What are the differences in homepage design and Web 2.0 technology practices between the 100 largest and 100 smallest Fortune 500 companies? and (5) Is homogeneity in design increasing amongst Fortune 500 homepages? Literature review: Three key areas guided my analysis of homepages. (1) Usability research, which suggests guidelines for design based on aggregated performance of users, such as locating the search box in the upper right and for directing mobile users to an alternate site designed for mobile access. (2) Design practice studies, which suggest guidelines for design based on aggregated analyses of websites, such as having links to employment information and investor information on the homepage.(3) Design patterns: libraries of patterns to provide designers with responses to design problems, such as using collapsible panels or module tabs to reveal and conceal content on a page. These libraries also provide guidelines for design, such as using fat menus or sitemap footers to structure navigation. Methodology: Using content analysis, every Fortune 500 homepage in 2013 was analyzed for 68 major design elements in these categories--navigation, content links, support for specific types of users, visual design, multimedia, and web 2.0-and the results were analyzed. Results and conclusions: The homepages displayed greater homogeneity in design than a similar study in 2008. Overall, 12 elements-(1) corporate logo in the top left of the page; (2) link to an "about us" section containing company information; (3) link to information for those seeking employment; (4) horizontally oriented main navigation; (5) link for contacting the company; (6) link for information for investors; (7) link for terms of use or legal disclaimers;(8) link to privacy information; (9) link for news or a press room; (10) multimedia use; (11) links that do not appear on the page initially, requiring interaction; (12) search box, located in the upper right of page-were present on 80% or more homepages, and 6 elements-(1) web 2.0 features; (2) an image that can be clicked on as a focal point; (3) link to a sitemap; (4) link to Twitter; (5) link to Facebook; and (6) dropdown or pulldown menu-were present on 50% to 79% of pages. Between 2008 and 2013, many practices have changed, such as increases in page length, the overall numb...

Retrievability is an important and interesting indicator that can be used in a number of ways to analyse Information Retrieval systems and document collections. Rather than focusing totally on relevance, retrievability examines what is retrieved, how often it is retrieved, and whether a user is likely to retrieve it or not. This is important because a document needs to be retrieved, before it can be judged for relevance. In this tutorial, we shall explain the concept of retrievability along with a number of retrievability measures, how it can be estimated and how it can be used for analysis. Since retrieval precedes relevance, we shall also provide an overview of how retrievability relates to e↵ectiveness -describing some of the insights that researchers have discovered thus far. We shall also show how retrievability relates to e ciency, and how the theory of retrievability can be used to improve both e↵ectiveness and e ciency. Then we shall provide an overview of the di↵erent applications of retrievability such as Search Engine Bias, Corpus Profiling, etc., before wrapping up with challenges and opportunities. The final session will look at example problems and ways to analyse and apply retrievability to other problems and domains. Participants are invited to bring their own problems to be discussed after the tutorial. This half-day tutorial is ideal for: (i) researchers curious about retrievability and wanting to see how it can impact their research, (ii) researchers who would like to expand their set of analysis techniques, and/or (iii) researchers who would like to use retrievability to perform their own analysis.
