Trust-Based Infinitesimals for Enhanced Collaborative Filtering

Maria Chowdhury, Alex Thomo, William W. Wadge
2009 International Conference on Management of Data  
In this paper we propose a novel recommender system which enhances user-based collaborative filtering by using a trust-based social network.  ...  Our main idea is to use infinitesimal numbers and polynomials for capturing natural preferences in aggregating opinions of trusted users.  ...  Trust-based Enhanced Collaborative Filtering 3 The trust horizon is parameter of Mole Trust which specifies the depth of neighbors in the trust graph that are considered by the method.  ...

2019 eLife  
We show that selection may favor de-repression of bone growth through inactivating two limb enhancers of an inhibitor, Nkx3-2.  ...  Our integrative genomic analyses thus show that it is possible to connect individual base-pair changes to the overall selection response.  ...  We thank Derek Lundberg for help with library preparation automation. We thank  ...

Ethics in Health Informatics

Kenneth W Goodman
2020 IMIA Yearbook of Medical Informatics  
Historical antecedents in statistics and evidence-based practice foreshadow some of the difficulties now faced, but the scope and scale of these challenges requires that ethics, too, be brought to scale  ...  They must, absolutely must, be held to trust-enhancing standards.  ...  Adopt standards for better software and testing. Do members of communities distrust those who collect and analyze personal information? Follow standards for trust enhancement.  ...

A Taxonomy-Based Model for Expertise Extrapolation

Delroy Cameron, Boanerges Aleman-Meza, I. Budak Arpinar, Sheron L. Decker, Amit P. Sheth
2010 2010 IEEE Fourth International Conference on Semantic Computing  
We present a novel semantics-based model for finding experts, expertise levels and collaboration levels in a peer review context, such as composing a Program Committee (PC) for a conference.  ...  The enrichment of Expertise Profiles for finding experts can therefore be facilitated by taking domain hierarchies into account.  ...  Trust propagation may show decadence rather than transitivity. Many challenges must be addressed when using publication data for finding experts.  ...

Semantic similarity based trust computation in websites

Hicham Ibrahim, Pradeep K. Atrey, Abdulmotaleb El Saddik
2007 Workshop on multimedia information retrieval on The many faces of multimedia semantics - MS '07  
Sreenath and Singh [14] presented an agent-based collaborative approach for computing the reputation of web services.  ...  This implies that time t = 0 for a particular website, $y(-l) is equal to some positive infinitesimal value.  ...  Therefore, the information found in health articles for this study did not present as high similarity measures as the sports domain or even the political news domain, for topics covered in several articles  ...

Awareness, Representation and Interpretation

Matthew Chalmers
2002 Computer Supported Cooperative Work (CSCW)  
We begin by briefly describing a prototype collaborative filtering system, Recer.  ...  We then take a more general look at collaborative filtering, and compare it with two other approaches to engendering awareness of useful artifacts: information retrieval and software patterns.  ...  First we consider collaborative filtering (CF) and its extension, the path model.  ...

High-Bandwidth Active Impedance Control of the Proprioceptive Actuator Design in Dynamic Compliant Robotics

Simon Hjorth Jessing Lund, Peter Billeschou, Leon Bonde Larsen
2019 Actuators  
The reason for this is that compliant mechanisms may ensure safe/compliant interactions between a robot and an external element—for instance, a human operator.  ...  Additionally, a novel speed and angle observer is proposed that aims to reduce noise arising in the angle sensor (typically a 12-bit magnetic encoder) and a Kalman/Luenberger based torque observer is proposed  ...  Acknowledgments: We acknowledge Carsten Albertsen and Cao Danh Do for technical support of the PCB and construction of the test configurations.  ...

Big IFs in Productivity-Enhancing Industry 4.0

Oliver Kovacs
2019 Social Sciences  
After applying a complexity view to the development of Industry 4.0 in deciphering the major IFs, the paper briefly exemplifies them by building on the case of Hungary, and it then draws some lessons for  ...  In general, (i) in the complex world economy, no nation state can face down intertwined wicked challenges alone (fighting for economic freedom is like chasing unviability); thus, broad-based collaborations  ...  Cautiousness is therefore in order for academics and economic policy engineers alike when it comes to expecting amazing productivity-enhancing impacts from Industry 4.0.  ...
