Cover Story: Evaluating the performance of big data applications is required to efficiently size capacities. This paper presents an approach to automatically extract system specifications to predict the performance of applications. It consists of three components. First, a system-agnostic domain-specific language (DSL) allows the modeling of performance-relevant factors. Second, DSL instances are automatically extracted from the measurements of Apache Spark systems. Third, these instances are transformed into simulation-based performance evaluation tools. By adapting DSL instances, our approach enables engineers to predict the performance of applications for different scenarios such as changing data input and resources. We evaluated our approach by predicting the performance of two machine learning applications. Simulation results show accurate prediction errors below 15% for response times and resource utilization.

Optimal Number of Choices in Rating Contexts

  • Sam Ganzfried and
  • Farzana Beente Yusuf

In many settings, people must give numerical scores to entities from a small discrete set—for instance, rating physical attractiveness from 1–5 on dating sites, or papers from 1–10 for conference reviewing. We study the problem of understanding when...

Archetype-Based Modeling and Search of Social Media

  • Brent D. Davis,
  • Kamran Sedig and
  • Daniel J. Lizotte

Existing keyword-based search techniques suffer from limitations owing to unknown, mismatched, and obscure vocabulary. These challenges are particularly prevalent in social media, where slang, jargon, and memetics are abundant. We develop a new techn...
