Battling the Internet water army: detection of hidden paid posters.

Chen, Cheng 04 July 2012 (has links)
Online social media, such as news websites and community question answering (CQA) portals, have made useful information accessible to more people. However, many of online comment areas and communities are flooded with fraudulent information. These messages come from a special group of online users, called online paid posters, or termed "Internet water army" in China, represents a new type of online job opportunities. Online paid posters get paid for posting comments or articles on different online communities and websites for hidden purpose, e.g., to influence the opinion of other people towards certain social events or business markets. Though an interesting strategy in business marketing, paid posters may create a significant negative effect on the online communities, since the information from paid posters is usually not trustworthy. We thoroughly investigate the behavioral pattern of online paid posters based on a real-world trace data from the social comments of a business conflict. We design and validate a new detection mechanism, including both non-semantic analysis and semantic analysis, to identify potential online paid posters. Using supervised and unsupervised approaches, our test results with real-world datasets show a very promising performance. / Graduate

Patienters med ADHD upplevelser och erfarenheter av hälsofrämjande åtgärder : en litteraturöversikt / Perspectives and experiences of patients with ADHD from health promotion measures : a literature review

Mikaelyan, Elza, Jevtic, Svetlana January 2022 (has links)
Bakgrund Attention-deficit hyperaktivitet disorder (ADHD) är en neurobeteendesjukdom som kännetecknas av tecken och symtom på ouppmärksamhet, hyperaktivitet och impulsivitet som vanligtvis börjar i barndomen. ADHD kan kvarstå i vuxen ålder och orsakar försämringar i yrkesprestation och kamrat- och familjerelationer.  För att få en djupare insikt i patienternas upplevelser och erfarenheter vid någon form av hälsofrämjande åtgärder, kommer författarna att göra en litteraturöversikt utifrån patientperspektivet. Syfte Syftet var att studera upplevelser och erfarenheter av hälsofrämjande åtgärder hos personer med ADHD Metod  En icke-systematisk litteraturöversikt prioriterades som forskningsmetod med kvalitativ och kvantitativ design. Artiklarna letades efter i PsycInfo och PubMed, med sökord som är adekvata för det aktuella syftet. En granskning utfördes av artiklarnas kvalitet för att vidare kunna kombineras i fyra huvudkategorier: nutrition, fysisk aktivitet, sömn och sjuksköterskeledda interventioner. Resultat Från fyra huvudkategorier skapades nio subkategorier, där ADHD-patientens upplevelser och erfarenheter framställs. Upplevda erfarenheter och upplevelser av interventioner kring fysisk aktivitet, nutrition, sömn och sjuksköterskeledda åtgärder skapar delaktighet och leder till minskning av ADHD-symtom. Patienterna upplevde att ett empatiskt förhållningssätt hos sjuksköterskor leder till förbättrad kommunikation och främjar relationer mellan patienter och vårdpersonalen som i sin tur leder till höjd effekt av de hälsofrämjande interventionerna och minskar följaktligen ADHD-symtomen. Slutsats Resultatet pekar på att hälsofrämjande interventioner har en allt igenom positiv effekt på personer med ADHD problematiken och deras upplevelser visar på att en utav viktigaste faktorerna är gruppgemenskapen och former av sjuksköterskeledda livsstilsförändringar, över lag alla former av handledning verkar vara gynnsamma för personer med ADHD och ett sätt med hjälp av de känner mindre av sina symtom. Handledning möjliggör att de lättare kan känna igen sina symtom och ändra på perspektivet så att de behåller fokus, vilket i sin tur möjliggör att de kan planera och slutföra sina vardagliga uppgifter trotts sina symtom. / Background Attention-deficit hyperactivity disorder (ADHD) is a neurological behavioral disorder characterized by signs and symptoms of inattention, hyperactivity and impulsivity that usually begin in childhood. ADHD can persist into adulthood and cause deterioration in professional performance and peer and family relationships. To gain a deeper insight into patients' experiences and experiences with some form of health-promoting measures, the authors will make a literature review from the patient perspective.   Aim The purpose was to study perspectives and experiences of health-promoting measures in people with ADHD. Method A non-systematic literature review was prioritized as a research method with qualitative and quantitative design. The articles included in this literature review were searched in PsycInfo and PubMed, with keywords that are appropriate for the current purpose. A review of the quality of the articles was performed to be further combined into four main categories: nutrition, physical activity, sleep and nurse-led interventions.   Results From four main categories, nine subcategories were created, where the patient with ADHD experiences and experiences are presented. The perceived experiences and experiences of interventions around physical activity, nutrition, sleep, and nurse-led measures create participation and lead to reduction of ADHD symptoms, patients experienced that an empathic approach in nurses leads to improved communication and promotes relationships between patients and caregivers as in their luck leads to an increase in the efficiency of health-promoting interventions that consequently reduces ADHD symptoms. Conclusions The results indicate that health-promoting interventions have a thoroughly positive effect on people with ADHD problems and their experiences show that one of the most important factors is the group community and forms of nurse-led lifestyle changes, in general all forms of guidance seem to be beneficial for people with ADHD and a way of helping of them feel less of their symptoms. Supervision enables them to recognize their symptoms and change their perspective so that they stay focused, which in turn enables them to plan and complete their daily tasks despite their symptoms more easily.
