Despite the help of search engines and Web directories, identifying high quality content becomes increasingly difficult as the Internet gets ever more crowded with information.


Identifying the effectiveness of a web search engine with Turkish domain dependent impacts and global scale information retrieval improvements
Fidan, Güven; Demirörs, Onur; Yöndem, Meltem Turhan; Department of Information Systems (2012)
This study investigates the effectiveness of a Web search engine with newly added or improved features in Web search engine architecture. These features can be categorized into three groups: The impact of link quality and usage information on page importance calculation; the use of Turkish stemmer for indexing and query substitution; and, the use of thumbnails for Web search engine result visualization. As Web search engines have become the primary means for finding and accessing information on the Internet...
The impact of a short-term training on student and teacher self-efficacy in computational thinking, programming and entrepreneurship
Huruzoğlu, Nevzat; Delialioğlu, Ömer; Department of Computer Education and Instructional Technology (2019)
Computational thinking, programming and entrepreneurship are three of the most important domains in 21st century, where the economies are internationalized and primarily based on information technology rather than traditional industry. It is therefore crucial to have individuals with high proficiency and high levels of selfefficacy in these domains, to be able to thrive and advance as a society. The primary purpose of this study, therefore, was to investigate the possible positive impact of a short-term tra...
Using Google analytics, card sorting and search statistics for getting insights about metu website’s new design: a case study
Dalcı, Mustafa; Taşkaya Temizel, Tuğba; Department of Information Systems (2011)
websites are one of the most popular and quickest way for communicating with users and providing information. Measuring the effectiveness of website, availability of information on website and information architecture on users‟ minds have become key issues. Moreover, using these insights on website‟s new design process will make the process more user-centered. v There is no consensus on how to define web site effectiveness, which dimensions need to be used for the evaluation of these web sites and which pro...
Understanding cognitive presence in an online and blended community of inquiry: Assessing outcomes and processes for deep approaches to learning
Akyol, Zehra; Garrison, D. Randy (2011-03-01)
This paper focuses on deep and meaningful learning approaches and outcomes associated with online and blended communities of inquiry. Applying mixed methodology for the research design, the study used transcript analysis, learning outcomes, perceived learning, satisfaction, and interviews to assess learning processes and outcomes. The findings for learning processes and outcomes indicated that students in both online and blended courses were able to reach high levels of cognitive presence and learning outco...
Second Chance: A Hybrid Approach for Dynamic Result Caching in Search Engines
Altıngövde, İsmail Sengör; Barla Cambazoglu, B.; Ulusoy, Ozgur (2011-01-01)
Result caches are vital for efficiency of search engines. In this work, we propose a novel caching strategy in which a dynamic result cache is split into two layers: an HTML cache and a docID cache. The HTML cache in the first layer stores the result pages computed for queries. The docID cache in the second layer stores ids of documents in search results. Experiments under various scenarios show that, in terms of average query processing time, this hybrid caching approach outperforms the traditional approac...
