Search results

This paper reports the findings of a major study examining the overlap among results retrieved by three major web search engines. The goal of the research was to: measure the overlap across three major web search engines on the first results page overlap (i.e. share the same results) and the differences across a wide range of user defined search terms; determine the differences in the first page of search results and their rankings (each web search engine's view of the most relevant content) across single‐source web search engines, including both sponsored and non‐sponsored results; and measure the degree to which a meta‐search web engine, such as Dogpile.com, provides searchers with the most highly ranked search results from three major single source web search engines.

The authors collected 10,316 random Dogpile.com queries and ran an overlap algorithm using the URL for each result by query. The overlap of first result page search for each query was then summarized across all 10,316 to determine the overall overlap metrics. For a given query, the URL of each result for each engine was retrieved from the database.

The percent of total results unique retrieved by only one of the three major web search engines was 85 percent, retrieved by two web search engines was 12 percent, and retrieved by all three web search engines was 3 percent. This small level of overlap reflects major differences in web search engines retrieval and ranking results.

This study provides an important contribution to the web research literature. The findings point to the value of meta‐search engines in web retrieval to overcome the biases of single search engines.

The results of this research can inform people and organizations that seek to use the web as part of their information seeking efforts, and the design of web search engines.

This research is a large investigation into web search engine overlap using real data from a major web meta‐search engine and single web search engines that sheds light on the uniqueness of top results retrieved by web search engines.

The purpose of this research is to show that federated content collections are important for providing access to multiple content repositories, including image, video, audio and Web sites.

This paper presents findings from an analysis of differences in users' Web searching patterns as they access various federated content collections. A dataset of 4,056,374 records submitted to the Dogpile.com Web meta‐search engine were analysed. An analysis was conducted of search session length, query length, number of results pages viewed, use of systems' assistance and the frequency of repeat queries.

Overall, users entered two to three terms per query and examined only the first pages of results. However, findings include differences in users' access patterns to various content collections. Web, news and audio queries were longer sessions but shorter queries. More users seeking images and videos sought systems assistance.

This is a large‐scale original study using data from a commercial Web search engine. The paper provides a valuable comparison of different types of search – text v. audio, image, etc.

Recent studies show that many Web users only submit short queries and conduct short search sessions. This paper examines aspects of users’ attempting longer more complex queries. Web search services such as Ask Jeeves – publicly accessible question and answer (Q&A) search engines – encourage queries in question or request format. In light of this trend, this study examines whether general Web queries are shifting towards a more question/request format. Previous studies show that some users were submitting question or request format queries to general non‐Q&A Web search engines. This paper re‐examines this issue by analysing large‐scale Web query data from two different (US and European) Web query data sets, including 1.2 million Excite queries (www.excite.com) and 1.2 million AlltheWeb.com (http://AlltheWeb.com) queries from 2001.

The World Wide Web is like a huge country, dotted with hundreds of thousands of sites, and each site contains some information. Despite the size of this country, transportation from any site to another requires only a mouse click and under the right conditions takes just a few moments.

Reviews the approaches to the organisation of knowledge in Web‐based environments. The control and structure helps searchers to locate information and services, but only provided that searchers understand and relate to the terms and information structure designed into the system. The other alternative is for the searcher to specify the topic of their search through the use of keywords. These keywords are in the natural language of the searcher, which may or not be coincident with the natural language of the Web sites being searched by the search engine. In order to negotiate the variability of natural language the searcher needs to learn to use more advanced search features such as Boolean searching, nesting and truncation. The knowledge organisation issues associated with access to and retrieval from large databases, such as those that are searched across the Web, are significant and need careful and specialist attention.

The purpose of this paper is to specify user‐defined relevance criteria by which people select hyperlinks and pages in web searching.

A quantitative and qualitative analysis was undertaken of talking aloud data from nine web searches conducted about self‐generated topics.

Altogether 18 different criteria for selecting hyperlinks and web pages were found. The selection is constituted, by two, intertwined processes: the relevance judgment of hyperlinks, and web pages by user‐defined criteria, and decision‐making concerning the acceptance or rejection of hyperlinks and web pages. The study focuses on the former process. Of the individual criteria, specificity, topicality, familiarity, and variety were used most frequently in relevance judgments. The study shows that despite the high number of individual criteria used in the judgments, a few criteria such as specificity and topicality tend to dominate. Searchers were less critical in the judgment of hyperlinks than deciding whether the activated web pages should be consulted in more detail.

The study is exploratory, drawing on a relatively low number of case searches.

The paper gives a detailed picture of the criteria used in the relevance judgments of hyperlinks and web pages. The study also discusses the specific nature of criteria used in web searching, as compared to those used in traditional online searching environments.

The interrelation between Web publishing and information retrieval technologies is explored. The different elements of the Web have implications for indexing and searching Web pages. There are two main platforms used for searching the Web – directories and search engines – which later became combined to create one‐stop search sites, resulting in the Web business model known as portals. Portalisation gave rise to a second‐generation of firms delivering innovative search technology. Various new approaches to Web indexing and information retrieval are listed. PC‐based search tools incorporate intelligent agents to allow greater manipulation of search strategies and results. Current trends are discussed, in particular the rise of XML, and their implications for the future. It is concluded that the Web is emerging from a nascent stage and is evolving into a more complex, diverse and structured environment.

The purpose of this paper is to assess student web searching competency. The paper aims to determine varying levels of university student competency in web searches and to investigate and compare their competency levels of searching academic and daily‐life tasks.

The study adopted a quantitative research method of giving study participants a controllable experiment, a task‐based online test (TBOT), to evaluate web searching competency based on student searching performance. Participants included 141 undergraduate and graduate students from Wuhan University, China. Their searching competency level was assessed by testing their searching effectiveness and searching efficiency.

Student average web searching competency level was found to be comparatively low overall, within preliminary stages of development. A lot of students are unable to search the web with efficiency. Competency levels for searching academic tasks were higher than those of daily‐life tasks, especially when the degree of difficulty increased. These two levels, however, have a significant positive correlationship. In information literacy education it is therefore vital to teach students comprehensive web searching competency that includes knowledge and techniques for both academic and daily‐life search tasks.

Using the TBOT to assess student web searching competency is novel in the field of library and information science. By conducting this pilot experiment, librarians and teachers will be able to design and promote an improved information literacy education according to students' specific web searching competency status, instead of assumed goal levels.

The purpose of this article is to alert researchers to software for web tracking of information seeking behaviour, and to offer a list of criteria that will make it easier to select software. A selection of research projects based on web tracking as well as the benefits and disadvantages of web tracking are also explored.

An overview of the literature, including clarification of key concepts, a brief overview of studies of web information seeking behaviour based on web tracking, identification of software used, as well as the strengths and short‐comings noted for web tracking is used as a background to the identification of criteria for the selection of web tracking software.

Web tracking can offer very valuable information for the development of websites, portals, digital libraries, etc. It, however, needs to be supplemented by qualitative studies, and researchers need to ensure that the tracking software will collect the data required.

The criteria is not applied to any software in particular.

The criteria can be used by researchers working on web usage and web information seeking behaviour to select suitable tracking software.

Although there are many reports on the use of web tracking (also reported in this article), nothing could be traced on criteria for the evaluation of web tracking software.

The purpose of this paper is to describe the aspects to be considered when evaluating web search engines' accessibility for people with disabilities. The authors provide an overview of related work and outline a theoretical framework for a comprehensive accessibility study of web search engines, regarding the principles of disability studies and the idea of inclusion.

The paper is based on a literature review, and an aggregation of recommended actions in practice, mainly the W3C Web Accessibility Initiative's (WAI) evaluation model.

A good way to conduct an accessibility study in a comprehensive manner is the WAI methodology consisting of three‐steps: preliminary review to quickly identify potential accessibility problems; conformance evaluation to determine whether a website meets established accessibility standards; and user testing to include real people with disabilities in a practical use. For the use case “web search engines” some special issues have to be taken into consideration.

The paper can be seen as a brainstorming and describes a theoretical concept of how to do. Conclusions about actual barriers of web search engines and criteria of satisfaction for people with disabilities do not exist as of yet; the model is not tested so far.

This paper provides practical implications for researchers who want to conduct an accessibility study, especially of web search engines. Findings of such studies can have practical implications for web search engine developers to improve accessibility of their product. The accessibility of web search engines does not only have implications for people with special needs, but also for the elderly or temporarily handicapped people.

This paper combines findings from web search engine research with aspects of disability studies. Therefore, it provides insights for researches, search engine developers and educators in practice on how important accessibility of web search engines for people with disabilities is, how it can be measured and what aspects need to be considered.
