2018 Knowledge engineering review (Print)  
However, reasoning approaches need to be scalable in order to enable reasoning over the entire Web of Data.  ...  In this large and uncoordinated environment, reasoning can be used to check the consistency of the data and of associated ontologies, or to infer logical consequences which, in turn, can be used to obtain  ...  Part of this work was done by Raghava Mutharaju when he was a PhD student at Wright State University during which time he acknowledges the support of the National Science Foundation under award 1017225  ...

2014 Proceedings of the International Astronomical Union  
We report on recently proposed statistical data analysis methods designed to study the primordial large-scale structure via physical inference of the initial conditions in a fully Bayesian framework, and  ...  We illustrate how this approach led to a detailed characterization of the dynamic cosmic web underlying the observed galaxy distribution, based on the tidal environment.  ...  Acknowledgements I thank Jacopo Chevallard, Jens Jasche and Benjamin Wandelt for a fruitful collaboration on the projects presented here.  ...

Why Choice of Survey Mode Makes a Difference

Don A. Dillman
2006 Public health reports (1974)  
The reason for his call was to ask me why the web survey was being answered by more unmarried people than the telephone survey.  ...  Recently, a surveyor who directs a large monthly survey of a general population called to tell me that a simple question he asked on marital status was producing different responses over the Internet than  ...

Semantic Web Research Anno 2006: Main Streams, Popular Fallacies, Current Status and Future Challenges [chapter]

Frank van Harmelen
2006 Lecture Notes in Computer Science  
We discuss the current status of the Semantic Web work by reviewing the current answers to four central research questions that need to be answered, and by surveying the uptake of Semantic Web technology  ...  We point to different interpretations of the Semantic Web as the reason underlying many controversies, we list (and debunk) four false objections which are often raised against the Semantic Web effort.  ...  That is exactly the reason why the construction of mappings between ontologies is such a core topic in the Semantic Web community (see [2, 3, 4] for some surveys).  ...

Interestingly, the largest effect was found for a scale of items involving computing and information technology.  ...  However, students who completed the Web-based survey responded more favorably than paper on all 8 scales. These patterns generally held for both women and men, and younger and older students.  ...  The exception is computing and information technology, which shows a .27 standard deviation increase if one responded via the Web instead of paper. 4 This scale is noteworthy for another reason: it is  ...

The opinions expressed here represent the views of the authors and not the funding agencies. Conflict of interest: none declared.  ...  This analysis showed that no particular interviewer had a large effect on the estimate (see Web Appendix).  ...  One source of data, which were collected by our research team, was a face-to-face survey admin-istered to a household-based random sample of 500 adult (i.e., aged 18 years) residents of Curitiba in 2010  ...

Can Mobile Web Surveys Be Taken on Computers? A Discussion on a Multi-Device Survey Design

2013 Survey Practice  
We present the findings of an experiment in which we provided one half of an online panel with a survey designed for mobile browsers, and the other half with a standard web survey.  ...  Based on these results, we discuss whether it is feasible to use a survey with a mobile web layout as the main survey instrument for web respondents.  ...  An experiment with an alternative approach, offering a survey with a mobile web layout to the whole web sample, shows that this approach has no effects on the survey outcomes when regular scale items are  ...
