In this study we examined how authority-related epistemological beliefs (AREBs) affect the evaluation of web search results presented by a search engine. Moreover, we investigated whether increasing the salience of source information on a search engine result page fosters students’ evaluation processes, and whether the salience of source information moderates the effects of AREBs. Thirty univer...

In this paper we will revise the recent developments in the field of automatic object extraction for change detection and GIS update under different aspects: (1) level of automation; (2) available sensors and image characteristics; (3) effectiveness and processing time; and (4) verification/editing and quality of results. For most applications, none of these aspects can be considered isolated f...

While most knowledge engineers believe that the quality of results obtained from Bayesian networks is not too sensitive to imprecision in probabilities, this remains a conjecture with only modest empirical support. Our work on a Bayesian network model for diagnosis of liver disorders, Hepar II, presented us with an opportunity to test this conjecture in a practical setting. We present the resul...

Understanding the performance of large, complex enterprise-class applications is an important, yet nontrivial task. Methods using hardware performance counters, such as profiling through event-based sampling, are often favored over instrumentation for analyzing such large codes, but rarely provide good accuracy at the instruction level. This work evaluates the accuracy of multiple eventbased sa...

Anna E. Bobkowska Technical University of Gdańsk, Poland [email protected] Abstract In order to achieve more maturity in modelling languages engineering, effective methods of visual modelling language evaluation are required. There is growing understanding of human factors’ impact on the quality of results and thus cognitive perspective seems to be a good frame of reference for evaluation. In...

Nearly every web search engine presents its results in an identical format: a ranked list of web page summaries. Each summary comprises a title; some sentence fragments usually containing words used in the query; and URL information about the page. In this study we present data from our pilot experiments with eye tracking equipment to examine how users interact with this standard list of result...

Many user queries nowadays contain references to named entities, which has motivated the development of new methods that exploit entity semantics for query expansion. At the same time, Wikipedia has been widely recognized as a large network of named entities, where entity-related articles are organized into a comprehensive hierarchy of categories and present summarized information on these enti...

In this paper we will discuss our eighteen-month progress of a three-year Instrument Incubator Program (IIP) funded by NASA Earth Science Technology Office (ESTO) on swath mapping laser altimetry system. This paper will discuss the system approach, enabling technologies and instrument concept for the swath mapping laser altimetry.

In this paper a modification of the Hopfield neural network solving the Travelling Salesman Problem (TSP) is proposed. Two strategies employed to achieve the solution and results of the computer simulations are presented. The network exhibits good performance in escaping from local minima of the energy surface of the problem. With a judicious choice of network internal parameters nearly 100% co...

Futures research means observation and understanding of today’s operational environment as well as identification and positioning of future opportunities. Lots of technology foresight and assessment initiatives are being made, probably in virtually all countries of the world. Articles concerning foresight rarely include assessments of what kind of materials they are based on. If they do, descri...
