	abstract = {The reuse of free and open source software (FOSS)
components is becoming more and more popular. They usually
contain one or more software licenses describing the requirements
and conditions which should be followed when been reused.
Licenses are usually written in the header of source code files as
program comments. Removing or modifying the license header
by re-distributors will result in the inconsistency of license with
its ancestor, and may potentially cause license infringement. But
to the best of our knowledge, no research has been devoted
to investigate such kind of license infringements nor license
inconsistencies. In this paper, we describe and categorize different
types of license inconsistencies and propose a feasible method to
detect them. Then we apply this method to Debian 7.5 and present
the license inconsistencies found in it. With a manual analysis, we
summarized various reasons behind these license inconsistencies,
some of which imply license infringement and require the attention
from the developers. This analysis also exposes the difficulty
to discover license infringements, highlighting the usefulness of
finding and maintaining source code provenance.},

	abstract = {Free and Open Source Software (FOSS) is widely reused today. To reuse FOSS one must accept the conditions imposed by the software license under which the component is made available. This is complicated by the fact that often FOSS packages contain files from many licenses. In this paper we analyze the source code of packages in the Fedora Core Linux distribution with the goal of discovering the relationship between the license of a source package, and the license of the files it contains. For this purpose we create license inclusion graphs. Our results show that more modern reciprocal licenses such as the General Public License v3 tend to include files of less licenses than its previous versions, and that packages under an Apache License tend to contain only files under the same license.},

	abstract = {In Open Source System (OSS) development, software components are often imported and reused; for this reason we might expect that files are copied in multiple projects (file clones). In this paper, we propose a file clone detection tool called FCFinder and show the analysis performed with it on the FreeBSD Ports Collection, a large OSS project collection. We found many file clones among similar or related projects, which are systematically introduced from base projects.},

We examined 136 versions of the stable Linux kernel using a distributed extension of the code clone detection tool CCFinder. The result is shown as a heat map.},
