报告题目：A theory of data patterns and visual analytics of football

报告摘要：

A fundamental goal of data analysis is to derive general, high-level knowledge from elementary data items, for example, derive understanding of the tactics of football teams from trajectories of the players and the ball. We consider knowledge to be a mental model of a piece of real world, which is the subject of analysis. A model represents overall relationships between different aspects or components of the analysis subject, such as space, time, groups of moving entities, and sets of actions and events. Data items describe elementary connections between individual elements of the subject components: spatial positions, time moments, entities, and so on. To derive understanding of overall relationships from elementary connections, we need to apply abstraction, in which multiple connections are considered together as a unified whole. The unification can be done with the help of relationships existing between elements within subject components, such as relationships of distance and direction between spatial locations and relationships of ordering and distance between time moments. We introduce a working definition of a data pattern as a combination of relationships between connected elements of two or more data components that can be considered and represented holistically as a single object, as, for example, a cluster, a trend, or a correlation. We discuss the roles of different types of relationships in forming data patterns. We illustrate the theoretical concepts using examples of football data. In the second part of our talk, we describe the process of designing an analytical workflow for finding tactical patterns in behaviours of teams in a football game.
