Dr. Muhammad Zubair Asghar

Sentiment analysis or opinion mining is the field of study related to analyze opinions, sentiments, evaluations, attitudes, and emotions of users which they express on social media and other online resources. The revolution of social media sites has also attracted the users towards video sharing sites, such as YouTube. The online users express their opinions or sentiments on the videos that they watch on such sites. This paper presents a brief survey of techniques to analyze opinions posted by users about a particular video.

The Symbiotic Relationship Between Information Retrieval And Informetrics, Dietmar Wolfram

Dietmar Wolfram

Informetrics and information retrieval (IR) represent fundamental areas of study within information science. Historically, researchers have not fully capitalized on the potential research synergies that exist between these two areas. Data sources used in traditional informetrics studies have their analogues in IR, with similar types of empirical regularities found in IR system content and use. Methods for data collection and analysis used in informetrics can help to inform IR system development and evaluation. Areas of application have included automatic indexing, index term weighting and understanding user query and session patterns through the quantitative analysis of user transaction logs. Similarly, developments …

Intelligent Water Drops Algorithm For Coordinating Between Cluster Spacecraft In A Communications-Denied Environment, Jeremy Straub

Jeremy Straub

This paper presents a modification of Shah-Hosseini’s Intelligent Water Drops (IWD) technique that can be utilized for collaborative control of multiple spacecraft in environments where communications are limited, intermittent or denied. It presents Shah- Hosseini’s base IWD algorithm as well as refinements thereof, which simplify it, making it more suitable for more computationally constrained environments (such as small spacecraft and UAVs). A framework for testing the proposed approach as well as several implementation impediments are discussed.

Using Cognitive Load Theory To Select An Environment For Teaching Mobile Apps Development, Raina Mason, Graham Cooper, Simon, Barry Wilks

Raina Mason

After considering a number of environments for the development of apps for mobile devices, we have evaluated five in terms of their suitability for students early in their programming study. For some of the evaluation we devised an evaluation scheme based on the principles of cognitive load theory to assess the relative ease or difficulty of learning and using each environment. After briefly presenting the scheme, we discuss our results, including our findings about which mobile apps development environments appear to show most promise for early-level programming students.

Alcts Crs Holdings Information Forum, 3-4 P.M. January 31, 2015, Connie Foster

Connie Foster

Cecilia Genereux (data management & access/metadata & intellectual access, University of Minnesota Libraries) introduced the session by confessing to a pun intended for her presentation: Alma: To Have and to Hold. The levity quickly shifted into some very detailed analysis of the way the Ex Libris Alma system handled specific types of serials during a migration from Aleph. The University of Minnesota started with Aleph (Ex Libris) in 2002 and moved to Alma on December 26, 2013. Frances McNamara (director, Integrated Library Systems and Administrative and Desktop Systems at University of Chicago), discussed migrating serials data from Horizon to Kulai …

Cepsim: A Simulator For Cloud-Based Complex Event Processing, Wilson Higashino, Miriam Capretz, Luiz Bittencourt

Wilson A Higashino

As one of the Vs defining Big Data, data velocity brings many new challenges to traditional data processing approaches. The adoption of cloud environments in complex event processing (CEP) systems is a recent architectural style that aims to overcome these challenges. Validating cloud-based CEP systems at the required Big Data scale, however, is often a laborious, error-prone, and expensive task. This article presents CEPSim, a new simulator that has been developed to facilitate this validation process. CEPSim extends CloudSim, an existing cloud simulator, with an application model based on directed acyclic graphs that is used to represent continuous CEP queries. …

Analyzing Latency-Aware Self-Adaptation Using Stochastic Games And Simulations, Javier Camara, Gabriel A. Moreno, David Garlan, Bradley Schmerl

Gabriel A. Moreno

Self-adaptive systems must decide which adaptations to apply and when. In reactive approaches, adaptations are chosen and executed after some issue in the system has been detected (e.g., unforeseen attacks or failures). In proactive approaches, predictions are used to prepare the system for some future event (e.g., traffic spikes during holidays). In both cases, the choice of adaptation is based on the estimated impact it will have on the system. Current decision-making approaches assume that the impact will be instantaneous, whereas it is common that adaptations take time to produce their impact. Ignoring this latency is problematic because adaptations may …

Proactive Self-Adaptation Under Uncertainty: A Probabilistic Model Checking Approach, Gabriel A. Moreno, Javier Camara, David Garlan, Bradley Schmerl

Gabriel A. Moreno

Self-adaptive systems tend to be reactive and myopic, adapting in response to changes without anticipating what the subsequent adaptation needs will be. Adapting reactively can result in inefficiencies due to the system performing a suboptimal sequence of adaptations. Furthermore, when adaptations have latency, and take some time to produce their effect, they have to be started with sufficient lead time so that they complete by the time their effect is needed. Proactive latency-aware adaptation addresses these issues by making adaptation decisions with a look-ahead horizon and taking adaptation latency into account. In this paper we present an approach for proactive …

Reasoning About Human Participation In Self-Adaptive Systems, Javier Camara, Gabriel A. Moreno, David Garlan

Gabriel A. Moreno

Self-adaptive systems overcome many of the limitations of human supervision in complex software-intensive systems by endowing them with the ability to automatically adapt their structure and behavior in the presence of runtime changes. However, adaptation in some classes of systems (e.g., safety- critical) can benefit by receiving information from humans (e.g., acting as sophisticated sensors, decision-makers), or by involving them as system-level effectors to execute adaptations (e.g., when automation is not possible, or as a fallback mechanism). However, human participants are influenced by factors external to the system (e.g., training level, fatigue) that affect the likelihood of success when they …

Legal Issues: Security And Privacy With Mobile Devices, Brian Leonard, Maurice Dawson

Maurice Dawson

Privacy and security are two items being woven into the fabric of American law concerning mobile devices. This chapter will review and analyze the associated laws and policies that are currently in place or have been proposed to ensure proper execution of security measures for mobile and other devices while still protecting individual privacy. This chapter will address the fact that as the American society significantly uses mobile devices, it is imperative to understand the legal actions surrounding these technologies to include their associated uses. This chapter will also address the fact that with 9/11 in the not so distant …

Data, Analytics And Community-Based Organizations: Transforming Data To Decisions For Community Development, Michael P. Johnson Jr.

Michael P. Johnson

The past ten years have seen a revolution in two disciplines related to operations and strategy design. “Big Data” has transformed the theory and practice of producing and selling goods and services through methods associated with computer science and information technology. “Analytics” has popularized primarily quantitative models and methods by which organizations and systems can measure multiple aspects of performance. As these fields rely on information technology to collect, store, process and share data, we refer to the collection of knowledge and applications associated with Big Data and analytics as “data analytics and information technology.” The impacts of data analytics …
