The online encyclopedia Wikipedia is a successful example of the increasing popularity of user generated content on the Web. Despite its success, Wikipedia is often criticized for containing low-quality information, which is mainly attributed to its core policy of being open for editing by everyone. The identiﬁcation of low-quality information is an important task since Wikipedia has become the primary source of knowledge for a huge number of people around the world. Previous research on quality assessment in Wikipedia either investigates only small samples of articles, or else focuses on single quality aspects, like accuracy or formality. This paper targets the investigation of quality ﬂaws, and presents the ﬁrst complete breakdown of Wikipedia's quality ﬂaw structure. We conduct an extensive exploratory analysis, which reveals (1) the quality ﬂaws that actually exist, (2) the distribution of ﬂaws in Wikipedia, and (3) the extent of ﬂawed content. An important ﬁnding is that more than one in four English Wikipedia articles contains at least one quality ﬂaw, 70% of which concern article veriﬁability.
