In recent years, there has been a huge increase in the number of bots online, varying from Web crawlers for search engines, to chatbots for online customer service, spambots on social media, and content-editing bots in online collaboration communities. The online world has turned into an ecosystem of bots. However, our knowledge of how these automated agents are interacting with each other is r...

Most of these opportunistic pursuits are exploited through automated programs, known as bots. We propose a framework (Stweeler) to study bot impact and influence on Twitter from systems and social media perspectives. Research Questions 1). About bots: Why do bots exist in such quantity in a large OSN such as Twitter? 2). Bot usage and impact: How do different entities, e.g. news corps or commer...

The popularity of social media platforms such as Twitter has led to the proliferation of automated bots, creating both opportunities and challenges in information dissemination, user engagements, and quality of services. Past works on profiling bots had been focused largely on malicious bots, with the assumption that these bots should be removed. In this work, however, we find many bots that ar...

Abstract. We study self-organized cooperation in a heterogeneous robotic swarm consisting of two sub-swarms. The robots of each sub-swarm play distinct roles based on their different characteristics. We investigate how the swarm as a whole can solve complex tasks through a self-organized process based on local interactions between the sub-swarms. We focus on an indoor navigation task, in which ...

Over the past few years, IRC bots, malicious programs which are remotely controlled by the attacker, have become a major threat to the Internet and its users. These bots can be used in different malicious ways such as to launch distributed denial of service (DDoS) attacks to shutdown other networks and services. New bots are implemented with extended features such as keystrokes logging, spammin...

Twitter is now an established and a widely popular news medium. Be it normal banter or a discussion on high impact events like Boston marathon blasts, February 2014 US Icestorm, etc., people use Twitter to get updates and also broadcast their thoughts and views. Twitter bots have today become very common and acceptable. People are using them to get updates about emergencies like natural disaste...

Tinder is a popular dating app that allows users to discover potential dating partners with close geographical proximity. Tinder is the first dating app in several countries and has more than 50 million users. However, many of these users are bots with malicious intent. The first step in dealing with this issue is understanding the characteristics of Tinder bots. Toward this aim, we have propos...

To further define the genetic events that could lead to the development ofborderline ovarian tumors (BOTs), we analyzed 13 microsateffite mark era on chromosomes 3p and q in 18 BOTs and compared the results to 31 serous invasive epithelial ovarian cancers (IEOCs). Five of the 18 BOTs showed microsateilite instability (MSI) at one or more loci, compared to only 2 ofthe 31 IEOCs StUdied(P < 0.04)...

Artbots have found limited fame—from wordplay bots on Twitter with thousands of followers, to bots made to show off the latest machine learning and AI techniques. Such bots may sometimes interact with human input, but almost never interact with other bots. When they do (Madrigal 2014), they do not learn from the other bots. This is a far cry from how real creative communities work, where practi...
