Measurement and evaluation of information systems and application: MEIS package

Evaluation and selection of case tools: a methodology and a case study Okşar, Koray; Okşar, Koray; Department of Information Systems (2010) Today’s Computer Aided Software Engineering (CASE) technology covers nearly all activities in software development ranging from requirement analysis to deployment.Organizations are evaluating CASE tool solutions to automate or ease their processes. While reducing human errors, these tools also increase control, visibility and auditability of the processes. However, to achieve these benefits, the right tool or tools should be selected for usage in the intended processes. This is not an easy task when the vas...
Characterizing web search queries that match very few or no results Altıngövde, İsmail Sengör; Cambazoglu, Berkant Barla; Ozcan, Rifat; Sarigil, Erdem; Ulusoy, Özgür (2012-12-19) Despite the continuous efforts to improve the web search quality, a non-negligible fraction of user queries end up with very few or even no matching results in leading web search engines. In this work, we provide a detailed characterization of such queries based on an analysis of a real-life query log. Our experimental setup allows us to characterize the queries with few/no results and compare the mechanisms employed by the major search engines in handling them.
Study on Q-RAM and Feasible Directions Based Methods for Resource Management in Phased Array Radar Systems Irci, Ayhan; Saranlı, Afşar; Baykal, Buyurman (2010-10-01) Our recent progress and results on optimal real-time resource allocation in phased array radar systems are reported. A previously proposed discrete resource allocation approach, the Quality of Service based Resource Allocation Model (Q-RAM), is analyzed and is observed to generate nonoptimal results. We identify the shortcomings of this method and first extend it using the Karush-Kuhn-Tucker (KKT) optimality conditions for the single resource type case. We obtain an algorithm that delivers a globally optima...
Proposal for an integrated breast diseases rsearch and national cancer registry system design and implementation Koçgil, Oya Deniz; Baykal, Nazife; Baykal, Ataç; Department of Information Systems (2003)
Assessing hospital information systems processes: a validation of prise information systems success model in healthcare Ozkan, Sevgi; Baykal, Nazife; Sincan, Murat (null; 2008-12-01) Although there is limited research and evidence base, it is reasonable to expect that high quality information technology is an integral factor in the success of today’s health care sector. However, the health care sector is considered to be low level investor in Information Technology (IT) when compared to other sectors. There are studies that look at the sums spent on health IT as a basis for determining how effective the IT systems are. We support the idea that the effectiveness of IT systems, is not an ...
