"Visualization is an important ingredient in understanding time series data"

Time-series data (also known as time-oriented data) represents sets of values changing over time and it is one of the most common forms of recorded data. Time-series data is being used in many domains such as finance (stock prices, exchange rates), science (heartbeat, temperatures, pollution levels, electric potentials), and public policy (crime rates, TV series). Time-oriented data is a good example for data with complex relationships, which is usually hard to understand without external help. Due to the importance and the frequency of use, visualization is an important ingredient in understanding time-series data, since it produces visual representations of complex relationships and in this way can help users efficiently allocate their attention in order to better understand the data. Even though the visualization plays a crucial role in understanding the data, it remains difficult and has many challenges. Current talk will address those challenges through examples from my research.

Bio: Julia Sheidin, is a PhD student in the Information Systems Department at University of Haifa under the supervision of Prof. Tsvi Kuflik and Dr. Joel Lanir. Her research examines how to explore the potential of Visual Analytics in reducing the overload users are facing when dealing with vast amounts of Multifaceted Temporal data. Julia did her Master degree in Information Systems (in University of Haifa), where she was a part of the collaboration project between the University of Haifa and the Italian Research Institute ITC-irst. The aim of the project was developing a Multimedia Mobile guide based PDA (Pocket PC), which allows group guided tour at the museum as a substitute for a human instructor. Julia’s master thesis topic was to design, implement and evaluate an adaptive user interface for mobile museum visitor’s guide. Afterwards, Julia worked for 7 years at Espro Acoustiguide Group, where her main job was to characterize, design and development of mobile applications in various work environments (iOS and Android products, company’s multimedia product). She is a full-time teaching teaching faculty at ORT Braude College in Karmiel, Israel, where she teaches Introduction to Software Engineering, Human Computer Interactions and Information Visualization.
