Author Profiling for Abuse Detection

Pushkar Mishra, Marco Del Tredici, Helen Yannakoudakis, Ekaterina Shutova
2018 International Conference on Computational Linguistics  
Experimenting with a dataset of 16k tweets, we show that our methods significantly outperform the current state of the art in abuse detection.  ...  The current state-of-the-art approaches to abuse detection are oblivious to user and community information and rely entirely on textual (i.e., lexical and semantic) cues.  ...  In this paper, we present the first approach to abuse detection that leverages author profiling information based on properties of the authors' social network and investigate its effectiveness.  ...

Abusive Language Detection with Graph Convolutional Networks [article]

Pushkar Mishra, Marco Del Tredici, Helen Yannakoudakis, Ekaterina Shutova
2019 arXiv   pre-print
Previous research on automated abusive language detection in Twitter has shown that community-based profiling of users is a promising technique for this task.  ...  We show that such a heterogeneous graph-structured modeling of communities significantly advances the current state of the art in abusive language detection.  ...  Acknowledgments We would like to thank the anonymous reviewers for their useful feedback. Helen Yannakoudakis was supported by Cambridge Assessment, University of Cambridge.  ...

Ability of Substance Abusers to Escape Detection on the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) in a Juvenile Correctional Facility

L. A. R. Stein, John R. Graham
2005 Assessment (Odessa, Fla.)  
For feigning substance abusers, only about 10% of substance abusers were detected, with about 72% being categorized as faking and needing further assessment.  ...  However, the Lie Scale (L) was able to detect more than 75% of deceptive profiles and about 77% of honest profiles.  ...  The authors gratefully acknowledge Beverly Kaemmer and the University of Minnesota Press for their support in completing this project.  ...

AN EFFECTIVE HEALTH CARE INSURANCE FRAUD AND ABUSE DETECTION SYSTEM

A J IKUOMOLA, O E Ojo
2017 Journal of Natural Sciences, Engineering and Technology  
Traditional methods of detecting health care fraud and abuse are time-consuming and inefficient. In this paper, the health care insurance fraud and abuse detection system (HECIFADES) was proposed.  ...  After testing, it was observed that HECIFADES was indeed an effective system for detecting fraudulent activities and yet very secured way for generating medical claims.  ...  The authors selected nine expense-related variables and compared them in two groups of fraudulent and nonfraudulent claims for building the detection models.  ...

Misuse detection for information retrieval systems

Rebecca Cathey, Ling Ma, Nazli Goharian, David Grossman
2003 Proceedings of the twelfth international conference on Information and knowledge management - CIKM '03  
Our approach is based on building and maintaining a profile of the behavior of the system user through tracking, or monitoring, of user activity within the information retrieval system.  ...  We propose three different methods to detect misuse in information retrieval systems. Our results favorably demonstrate the validity of our approach.  ...  Any new activity of the user is compared to the user profile to detect a potential misuse for the authorized user.  ...

Detecting Credential Abuse in the Grid Using Bayesian Networks

Christopher Kunz, Nina Tahmasebi, Thomas Risse, Matthew Smith
2011 2011 IEEE/ACM 12th International Conference on Grid Computing  
Proxy Credentials serve as a principal for authentication and authorization in the Grid. Despite their limited lifetime, they can be intercepted and abused by an attacker.  ...  Our approach combines modifications to the security infrastructure with a Bayesian classifier in order to provide a reliable method for detecting abusive Grid credential usage and alerting the legitimate  ...  Proxy Credentials serve as a principal for authentication and authorization in the Grid.

Aviad Elyashar, Jorge Bendahan, Rami Puzis
2018 arXiv   pre-print
The detection of online discussion topics manipulated by OSM abusers is an emerging issue attracting significant attention.  ...  Some individuals view OSM as fertile ground for abuse and use it to disseminate misinformation and political propaganda, slander competitors, and spread spam.  ...  ACKNOWLEDGMENT The authors would like to thank Robin Levy-Stevenson for proofreading this article.  ...

Manuel Pabón-Carrasco, Lucia Ramirez-Baena, Nerea Jiménez-Picón, José Antonio Ponce Blandón, José Manuel Martínez-Montilla, Raúl Martos-García
2019 International Journal of Environmental Research and Public Health  
Various studies suggest that the personality of teenagers is a risk profile for bullying.  ...  The results showed that 14% (n = 13) of the sample were detected as victims and another 14% (n = 13) were detected as aggressors.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

AIS-based profiling of fishing vessels falls short as a "proof of concept" for identifying forced labor at sea

Wilf Swartz, Andrés M. Cisneros-Montemayor, Gerald G. Singh, Patrick Boutet, Yoshitaka Ota
2021 Proceedings of the National Academy of Sciences of the United States of America  
The authors create profiles from vessels reported to have committed labor abuses, search for similar profiles in a database of 16,000 vessels with available positioning (automatic identification system  ...  In conclusion, McDonald et al. falls short as a "proof of concept," and therefore, the capacity of remote sensing as a tool for detecting fishing vessels engaged in labor abuses remains unsubstantiated  ...

Too good to be true? Predicting author profiles from abusive language [article]

Isabelle van der Vegt, Bennett Kleinberg, Paul Gill
2020 arXiv   pre-print
The problem of online threats and abuse could potentially be mitigated with a computational approach, where sources of abuse are better understood or identified through author profiling.  ...  This study examines statistical relationships between author demographics and abusive vs normal language, and performs prediction experiments for personality, age, and gender.  ...  In our view, an important step has been missed in the use of author profiling for threat assessment; the link between author characteristics and abusive language remains unestablished.  ...
