Professor Daniel German from the University of Victoria gave a talk.

## Overview of presentation

### Title

From Snippets to Identifiers

### Presenter

Daniel M. German (the University of Victoria, Canada)

### Abstract

In this presentation I will describe recent work we have been doing in two different areas: The first is a qualitative empirical study of Stack Overflow idioms, with the goal to try to understand how the snippets that answer a programming problem are found within the answer of a question. Stack Overflow answers usually contain much more than just the actual source code that answers the question, such as examples of how to use the solution snippet, counterexamples, placeholders for code that is to be written, etc. The second is a quantitative empirical study of global identifiers in the PyPI ecosystem. In this study of 240k different PyPI products, we found 11 million different global identifiers (classes, method of functions). 76% of these identifiers were unique to one product, and 93% appeared in at most 3. This discovery allowed us to create an efficient method to identify the origin software product (within PyPI) of a file (or set of files).

Senior Lecturer Christoph Treude from University of Melbourne gave a talk.

## Overview of presentation

### Title

Representation and Dissemination of Programming Knowledge

### Presenter

Christoph Treude (University of Melbourne, Australia)

### Abstract

In the early days of programming, documentation used to exist only in scarce source code comments and quickly-outdated textbooks. Over the past twenty years, the advent and rise of web-based collaboration platforms have substantially changed the way programming knowledge is externalized and accessed and it has created a new research challenge: how can we effectively process and make sense of the large amount and wide variety of information available to support programmers' decision making? In this talk, I will portray the maturation of a research area, from studies on the information needs of programmers and qualitative analyses of the information contained in different sources, to documentation generation and retrieval approaches which integrate information from different sources. To enable more comprehensive approaches which can utilize all relevant knowledge, I will conclude with a roadmap outlining a more systematic treatment of information from different sources, based on knowledge graphs, multi-document summarisation, and source code representations for machine learning applications.
