The relevant literature is reviewed to provide a systematic overview of suitable ranking factors. The discussion is based on an overview of ranking factors used in Web search engines.
When designing a ranking component for the library catalogue, an individual weighting of applicable factors is necessary.
While this article discusses different factors, no particular ranking formula is given. However, this article presents the argument that such a formula must always be individual to a certain use case.
This paper is original in that it is the first to systematically discuss ranking of library materials based on the main factors used by Web search engines.
Information Retrieval and Information retrieval Library Science. Real Time Suche more. Using search engine technology to improve library catalogs more.
Findings were that the major shortcomings of current OPACs are that they are not sufficiently user-centered and that their results presentations lack sophistication.
Further, these shortcomings are not addressed in current 2. It is argued that OPAC development should be made search-centered before additional features are applied.
While the recommendations on ranking functionality and the use of user intentions are only conceptual and not yet applied to a library catalogue, practitioners will find recommendations for developing better OPACs in this chapter.
Google Scholar as a tool for discovering journal articles in library and information science more. We also collected information on the type of availability— i.
We found that only some journals are completely indexed by Google Scholar, that the ratio of versions available depends on the type of publisher, and that availability varies a lot from journal to journal.
Google Scholar cannot substitute for abstracting and indexing services in that it does not cover the complete literature of the field. However, it can be used in many cases to easily find available full texts of articles already found using another tool.
This study differs from other Google Scholar coverage studies in that it takes into account not only whether an article is indexed in GS at all, but also the type of availability.
Auch im Jahr ist die Suchmaschinenlandschaft durch einen stetigen Wandel gekennzeichnet. The retrieval effectiveness of search engines on navigational queries more.
Purpose — To test major Web search engines on their performance on navigational queries, i. Users described the desired pages, and the results position of these is recorded.
Measured success N and mean reciprocal rank are calculated. Findings — Performance of the major search engines Google, Yahoo, and MSN is best, with around 90 percent of queries answered correctly.
Ask and Exalead perform worse but receive good scores as well. Therefore, the results are only valid for German queries.
Practical implications — When designing a search engine to compete with the major search engines, care should be taken on the performance on navigational queries.
Users can be influenced easily in their quality ratings of search engines based on this performance. Ranking of Wikipedia articles revisited: Fair ranking for reasonable quality?
This paper aims to review the fiercely discussed question of whether the ranking of Wikipedia articles in search engines is justified by the quality of the articles.
After an overview of current research on information quality in After an overview of current research on information quality in Wikipedia, a summary of the extended discussion on the quality of encyclopedic entries in general is given.
On this basis, a heuristic method for evaluating Wikipedia entries is developed and applied to Wikipedia articles that scored highly in a search engine retrieval effectiveness test and compared with the relevance judgment of jurors.
In all search engines tested, Wikipedia results are unanimously judged better by the jurors than other results on the corresponding results position.
Relevance judgments often roughly correspond with the results from the heuristic evaluation. Cases in which high relevance judgments are not in accordance with the comparatively low score from the heuristic evaluation are interpreted as an indicator of a high degree of trust in Wikipedia.
One of the systemic shortcomings of Wikipedia lies in its necessarily incoherent user model. A further tuning of the suggested criteria catalogue, for instance the different weighing of the supplied criteria, could serve as a starting point for a user model differentiated evaluation of Wikipedia articles.
Approved methods of quality evaluation of reference works are applied to Wikipedia articles and integrated with the question of search engine evaluation.
Umgang mit Information Overload more. In diesem Kapitel wird der Begriff diskutiert und es wird auf die wichtigsten In diesem Kapitel wird der Begriff diskutiert und es wird auf die wichtigsten Strategien im Umgang mit einem Zuviel an Informationen eingegangen.
Informationskompetenz und das Potenzial der Internetsuchmaschinen more. New perspectives on Web search engine research more.
This chapter presents a theoretical framework for evaluating next generation search engines. While Web search is used as an example here, the framework can easily be applied to search engines in any other area.
The framework not only addresses the results presentation, but also takes into account an extension of the general design of retrieval effectiveness tests.
The chapter examines the ways in which this design might influence the results of such studies and how a reliable test is best designed.
Credibility in Web Search Engines more. Web search engines apply a variety of ranking signals to achieve user satisfaction, i.
While these ranking signals implicitly consider credibility e. In this chapter, credibility in Web search engines is discussed in a broad context: It is found that while search engines—at least to a certain extent—show credible results to their users, there is no fully integrated credibility framework for Web search engines.
The purpose of this paper is to test the reliability of query intents derived from queries, either by the user who entered the query or by another juror.
We report the findings of three studies: First, we conducted a large-scale First, we conducted a large-scale classification study approximately 50, queries using a crowdsourcing approach.
Then, we used click-through data from a search engine log and validated the judgments given by the jurors from the crowdsourcing study. Since we used the same queries for all three studies, we were able to compare the results and the effectiveness of the different approaches, as well.
We found that neither the crowdsourcing approach using jurors who classified queries originating from other users, nor the questionnaire approach using searchers who were asked about their own query that they just entered into a web search engine, lead to satisfying results.
This leads us to conclude that there is little understanding of the classification tasks, even though both groups of jurors were given detailed instructions.
While we used manual classification, our research has important implications for automatic classification, as well.
We must question the success of approaches using automatic classification and comparing its performance to a baseline from human jurors.
Accessibility of Web Search Engines: Towards a deeper understanding of barriers for people with disabilities more. Search engines are one of the most important and most-used services on the web.
It is important to consider the relevance of web search engines and their accessibility for people with disabilities because these tools are fundamental to self-determined and independent living.
They can use alternative opportunities for access, and they can be supported by assistive technologies AT e. However, to make these technologies fully functional in the context of web searching, search engines need to be accessible for everyone.
This paper seeks to introduce the concept of web accessibility, to review related work and established recommendations about evaluating web accessibility, and to apply the well-tried design of accessibility surveys for websites to web search engines.
The intention of the paper is to identify web search engine accessibility as an important topic of research and to develop a theoretical framework for evaluation, including an aggregation of relevant sources.
Challenges for search engine retrieval effectiveness evaluations: Universal Search and user intents, and results presentation more.
This chapter discusses evaluating the quality of Web search engines to effectively retrieve information. It identifies three factors that lead to a need for new evaluation methods: It discusses implications for evaluation methodology and provides some suggestions about measures.

Search engines need to look for new documents constantly, detect changes made to existing documents, and remove documents from the Search engines need to look for new documents constantly, detect changes made to existing documents, and remove documents from the index when they are no longer available on the web.
When one considers that the web comprises many billions of documents that are constantly changing, the challenge search engines face becomes clear.
It is impossible to maintain a perfectly complete and current index. The pool of data changes thousands of times each second. No search engine can keep up with this rapid pace of change.

We found that German-language information science is not a close-knit community. From the cluster analysis, we can conclude that German-language information scientist work in areas rather distant from one another.
Evaluating the retrieval effectiveness of Web search engines using a representative query sample more. Search engine retrieval effectiveness studies are usually small-scale, using only limited query samples.
Furthermore, queries are selected by the researchers. We address these issues by taking a random representative sample of 1, Jurors were found through crowdsourcing, data was collected using specialised software, the Relevance Assessment Tool RAT.
We found that while Google outperforms Bing in both query types, the difference in the performance for informational queries was rather low.
However, for navigational queries, Google found the correct answer in We conclude that search engine performance on navigational queries is of great importance, as users in this case can clearly identify queries that have returned correct results.
So, performance on this query type may contribute to explaining user satisfaction with search engines. Living in a world of biased search engines more.
When looking at Internet usage, we see that searching is one of the dominant activities Purcell et al. We all search every day, and we predominantly use Google for that purpose.
While Yahoo is often regarded as a search engine, the company gave up their own search technology in and have been showing results provided by Bing since then.
Ranking search results in library information systems — considering ranking approaches adapted from web search engines more.
For an information retrieval system to be successful, it must have the ability to rank search results. As web search engines are the most often used and — in terms of ranking functionality — the most advanced existing systems, the As web search engines are the most often used and — in terms of ranking functionality — the most advanced existing systems, the principles they are based on and the strategies they use can be advantageous when applied to the library context.
We categorize ranking factors into six different groups: We discuss the basic concepts and assumptions these ranking factors involve and offer potential implementations in the library context.
The practice recommended here is for libraries to not only apply selected ranking factors — as existing library information systems already do — but to systematically test for the ranking factors best suited to their systems.
We argue for a user-centric view on ranking, because in the end, ranking should be for the benefit of the user, and user preferences may vary across different contexts.
