Students Satisfaction

Introduction. Most university students depend significantly, sometimes exclusively, on the Google search engine for their academic information needs. User satisfaction leads to users’ deeper engagement with an information system that is shown to improve learning in an educational setting. This paper evaluates students’ satisfaction with results from personalised Web search against non-personalised Web search. Method. During semi-structured study sessions, twenty-eight participants (university students) were required to complete a series of search tasks using both personalised and non-personalised Web search. Analysis. Evaluation was based on participants’ explicit feedback as well as their implicit behaviour including search time, number of queries and clicked result links per task, finding the answer and relevance of the search results. Results. There was no apparent significant increase in the participants’ overall level of satisfaction with personalised search results compared to non-personalised results. However, it was found that personalised search reduced the time spent to finish a task and reduced the number of clicks required to arrive at the selected outcome. Conclusions. Personalisation of search results does not increase students' satisfaction with their search results. However, it does reduce the time spent by students in locating information they judged to be satisfactory answers to their questions.

AbstractThere are limited studies that are addressing the challenges of visually impaired (VI) users when viewing search results on a search engine interface by using a screen reader. This study investigates the effect of providing an overview of search results to VI users. We present a novel interactive search engine interface called InteractSE to support VI users during the results exploration stage in order to improve their interactive experience and web search efficiency. An overview of the search results is generated using an unsupervised machine learning approach to present the discovered concepts via a formal concept analysis that is domain-independent. These concepts are arranged in a multi-level tree following a hierarchical order and covering all retrieved documents that share maximal features. The InteractSE interface was evaluated by 16 legally blind users and compared with the Google search engine interface for complex search tasks. The evaluation results were obtained based on both quantitative (as task completion time) and qualitative (as participants’ feedback) measures. These results are promising and indicate that InteractSE enhances the search efficiency and consequently advances user experience. Our observations and analysis of the user interactions and feedback yielded design suggestions to support VI users when exploring and interacting with search results.

This study aimed to find out the use of open library digital library services  in meeting the information needs of Telkom University students. The study used the qualitative method with case study approach. Data collection techniques were conducted through interviews with Telkom University students, observation, and literature study. Study results showed that the initial stage was based on the motivation and goals arising from self-awareness and the need to increase knowledge in completing tasks and scientific works (thesis/TA). Browsing began with authentication using an SSO account (Igracias), and information retrieval began with using a simple search facility. Students also used the internet to access various other sources with the Google search engine to further enrich the required information. Then, At the formulation stage, students conducted brainstorming by learning and understanding the problem-solving process related to the appropriate topic and discussing it with friends, lecturers, or people who were considered understandable and could be invited to discuss related topics that were being deepened. The collection stage was done by downloading the file and storing it in their laptop folder. At the presentation stage, students would feel satisfied after getting the information so it is possible to do monitoring.  The presentation was performed in the form of writing a new document or as a complement in both the completion of lecture assignments (proposal and paper) as well as the writing of scientific papers (thesis/TA).

The result of a typical web search is often overwhelming. It is very difficult to explore the textual listing of the resulting documents, which may be in the thousands. In order to improve the utility of the search experience, we explore presenting search results through clustering and a zoomable two-dimensional map (zoomable treemap). Furthermore, we apply the fisheye view technique to this map of web search clusters to provide details in context. In this study, we report on our evaluation of these presentation features. The particular interfaces evaluated were: (1) a textual list, (2) a zoomable two-dimensional map of the clustered results, and (3) a fisheye version of the zoomable two dimensional map where the results were clustered. We found that subjects completed search tasks faster with the visual interfaces than with the textual interface, and faster with the fisheye interface than just the zoomable interface. Based on the findings, we conclude that there is promise in the use of clustering and visualization with a fisheye zooming capability in the exploration of web search results.

People commonly experience difficulties when searching the Web, arising from an incomplete knowledge regarding their information needs, an inability to formulate accurate queries, and a low tolerance for considering the relevance of the search results. While simple and easy to use interfaces have made Web search universally accessible, they provide little assistance for people to overcome the difficulties they experience when their information needs are more complex than simple fact-verification. In human-centred Web search, the purpose of the search engine expands from a simple information retrieval engine to a decision support system. People are empowered to take an active role in the search process, with the search engine supporting them in developing a deeper understanding of their information needs, assisting them in crafting and refining their queries, and aiding them in evaluating and exploring the search results. In this chapter, recent research in this domain is outlined and discussed.

Explicit Measures

Web search engines apply a variety of ranking signals to achieve user satisfaction, i.e., results pages that provide the best-possible results for the user. While these ranking signals implicitly consider credibility (e.g., by measuring popularity), explicit measures of credibility are not applied. In this chapter, credibility in Web search engines is discussed in a broad context: credibility as a measure for including documents in a search engine’s index, credibility as a ranking signal, credibility in the context of universal search results, and the possibility of using credibility as an explicit measure for ranking purposes. 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.

This study explored relationships between Internet-specific justification beliefs and source evaluation and corroboration during Web search. Fifty university students completed the Internet-Specific Epistemic Justification Inventory (ISEJ), which targeted beliefs concerning the justification of Internet-based knowledge claims about natural science issues. Two to five days later, they conducted a Web search in order to communicate a justified position regarding an unsettled and unfamiliar socio-scientific issue. Using think-aloud and trace methodologies, participants’ source evaluation and corroboration behaviors were examined. Furthermore, the extent and relevance of their post-search written justifications for their recommendation about the controversial issue were analyzed. Results showed that beliefs in justification by authority positively predicted comments regarding source evaluation, the percentage of visited websites that were listed beyond the first three Google search results, and the likelihood of opening multiple browser tabs. Beliefs in personal justification negatively predicted comments regarding corroboration of information across websites and the number of relevant aspects included in the written justifications. Finally, participants with stronger beliefs in justification by multiple sources gave more extensive justifications for their recommendation and included more relevant aspects in those justifications.

Only 10 or 15 years ago, you had to spend hours, days or even weeks in libraries to find data of many kinds. Today, one has access to data at your desks at home. Therefore, the biggest problem for a real information society is not that you do not have access to the needed data, but that you cannot find it or that it takes so long to find it that you quit the search before finding the result. This is clearly shown by a Google search where you get so many results that can lead to a case of information stress or even worse information death. An easy search route and a short search time are important elements when trying to satisfy certain information needs. This topic is discussed based on two case studies: one concerning certain fixed expressions in seven Danish printed and electronic dictionaries and one concerning looking at different access attempts in six Afrikaans reference sources, including linguistic text books, books presenting the formal spelling and orthographic rules of Afrikaans as well as a monolingual dictionary. The paper argues that the applicability of the access process, as developed in lexicography, goes beyond dictionaries, illustrating the importance of a process not relevant within the field of linguistics but extremely important in the successful use of reference works.
