Rationale in Development Chat Messages: An Exploratory Study
Chat messages of development teams play an increasingly significant role in
software development, having replaced emails in some cases. Chat messages
contain information about discussed issues, considered alternatives and
argumentation leading to the decisions made during software development. These
elements, defined as rationale, are invaluable during software evolution for
documenting and reusing development knowledge. Rationale is also essential for
coping with changes and for effective maintenance of the software system.
However, exploiting the rationale hidden in the chat messages is challenging
due to the high volume of unstructured messages covering a wide range of
topics. This work presents the results of an exploratory study examining the
frequency of rationale in chat messages, the completeness of the available
rationale and the potential of automatic techniques for rationale extraction.
For this purpose, we apply content analysis and machine learning techniques on
more than 8,700 chat messages from three software development projects. Our
results show that chat messages are a rich source of rationale and that machine
learning is a promising technique for detecting rationale and identifying
different rationale elements.Comment: 11 pages, 6 figures. The 14th International Conference on Mining

Analysis and Detection of Information Types of Open Source Software Issue Discussions
Most modern Issue Tracking Systems (ITSs) for open source software (OSS)
projects allow users to add comments to issues. Over time, these comments
accumulate into discussion threads embedded with rich information about the
software project, which can potentially satisfy the diverse needs of OSS
stakeholders. However, discovering and retrieving relevant information from the
discussion threads is a challenging task, especially when the discussions are
lengthy and the number of issues in ITSs are vast. In this paper, we address
this challenge by identifying the information types presented in OSS issue
discussions. Through qualitative content analysis of 15 complex issue threads
across three projects hosted on GitHub, we uncovered 16 information types and
created a labeled corpus containing 4656 sentences. Our investigation of
supervised, automated classification techniques indicated that, when prior
knowledge about the issue is available, Random Forest can effectively detect
most sentence types using conversational features such as the sentence length
and its position. When classifying sentences from new issues, Logistic
Regression can yield satisfactory performance using textual features for
certain information types, while falling short on others. Our work represents a
nontrivial first step towards tools and techniques for identifying and
obtaining the rich information recorded in the ITSs to support various software
engineering activities and to satisfy the diverse needs of OSS stakeholders.Comment: 41st ACM/IEEE International Conference on Software Engineering

Security Code Smells in Android ICC
Android Inter-Component Communication (ICC) is complex, largely
unconstrained, and hard for developers to understand. As a consequence, ICC is
a common source of security vulnerability in Android apps. To promote secure
programming practices, we have reviewed related research, and identified
avoidable ICC vulnerabilities in Android-run devices and the security code
smells that indicate their presence. We explain the vulnerabilities and their
corresponding smells, and we discuss how they can be eliminated or mitigated
during development. We present a lightweight static analysis tool on top of
Android Lint that analyzes the code under development and provides just-in-time
feedback within the IDE about the presence of such smells in the code.
Moreover, with the help of this tool we study the prevalence of security code
smells in more than 700 open-source apps, and manually inspect around 15% of
the apps to assess the extent to which identifying such smells uncovers ICC
security vulnerabilities.Comment: Accepted on 28 Nov 2018, Empirical Software Engineering Journal

Curating E-Mails; A life-cycle approach to the management and preservation of e-mail messages
E-mail forms the backbone of communications in many modern institutions and organisations and is a valuable type of organisational, cultural, and historical record. Successful management and preservation of valuable e-mail messages and collections is therefore vital if organisational accountability is to be achieved and historical or cultural memory retained for the future. This requires attention by all stakeholders across the entire life-cycle of the e-mail records.
This instalment of the Digital Curation Manual reports on the several issues involved in managing and curating e-mail messages for both current and future use. Although there is no 'one-size-fits-all' solution, this instalment outlines a generic framework for e-mail curation and preservation, provides a summary of current approaches, and addresses the technical, organisational and cultural challenges to successful e-mail management and longer-term curation.
Collaboration Enabling Internet Resource Collection-Building Software and Technologies
Over the last decade the Library of the University of California, Riverside
and its collaborators have developed a number of systems, service designs,
and projects that utilize innovative technologies to foster better Internet
finding tools in libraries and more cooperative and efficient effort in Internet
link and metadata collection building. The open-source software
and projects discussed represent appropriate technologies and sustainable
strategies that we believe will help Internet portals, digital libraries, virtual libraries,
library catalogs-with-portal-like-capabilities (IPDVLCs), and related
collection-building efforts in academia to better scale and more accurately
anticipate and meet the needs of scholarly and educational users.published or submitted for publicatio
