Since Wikipedia is a web genre, "Wikicussions" (as the authors call them) form a subgenre. In this context, talk pages are examined further, including the quality of cooperation between Wikipedia users, that can be linked to social differentiation regarding roles and statuses of Wikipedians (content- vs. administration-related users). These group-related processes can be seen as a mediating layer between external parameters (system requirements for Wikipedia's user community) and the structure and dynamics of WP's subgenres.

Unlike face-to-face dialogue, the authors argue that Wikicussions stand out due to a publicly available common ground (derived from dialogue theory), which may provide a reason for the structures they found.

The paper is enriched with a number of high-quality figures that support and underpin the findings.

Unsigned posts (without timestamps) are excluded.

===="How Sudden Censorship Can Increase Access to Information"====
:<small>''Reviewed by {{U|Bri}} and [[en:User:Tbayer (WMF)|Tilman Bayer]]''</small>
Our intuition might tell us that government censorship causes reduced access to online information. But recent research indicates that the effect can be exactly the opposite. Using data gathered from Wikipedia page views and other sources, researchers William Hobbs and Margaret Roberts found that:
{{Quotebox|[...] citizens accustomed to acquiring this [forbidden] information will be incentivized to learn methods of censorship evasion&nbsp;[...] millions of Chinese users acquire[d] [[:w:virtual private network|virtual private network]]s, and subsequently&nbsp;[...] began browsing blocked political pages on Wikipedia, following Chinese political activists on Twitter, and discussing highly politicized topics such as opposition protests in Hong Kong.<ref name="Hobbs2018">{{Cite journal|last1=Hobbs|first=William R.|last2=Roberts|first2=Margaret E.|title=How Sudden Censorship Can Increase Access to Information|journal=[[:w:American Political Science Review|American Political Science Review]]|publisher=[[:w:Cambridge University Press|Cambridge University Press]]|publication-date=April 2, 2018|volume=<!--No volume, online publication.-->|issue=<!--No issue, online publication.-->|pages=1–16|doi=10.1017/S0003055418000084|issn=0003-0554|oclc=7435466814}}&nbsp;{{closed access}}</ref>}}

Specifically, the authors studied the impact of a block of [[:w:Instagram|Instagram]] in China on September 29, 2014, following protests in Hong Kong, on Chinese Wikipedia pages that were already blocked in the country. (This predates the 2015 total block of the Chinese Wikipedia and the switch of all Wikimedia sites to full encryption with HTTPS around the same time, which made such per-page blocking impossible.) The censored Chinese Wikipedia pages with the largest increase in views "shows that new viewers accessed pages that had long been censored including those related to the 1989 Tiananmen Square protests",<ref name="Hobbs2018" /> i.e. "viewing patterns that would be more typical of new users who had just jumped the firewall, rather than of old VPN users who had presumably consumed this information long ago."<ref name="Hobbs2018" /> Here is an excerpt of the full list examined in the research, the top 10 for the second day of the block, linked here to their English Wikipedia equivalents:
#[[:w:Websites blocked in mainland China|People's Republic of China blocked websites list]]
#[[:w:Jiang Zemin|Jiang Zemin]]
#[[:w:Radio Australia|Radio Australia]]
#[[:w:Hu Jintao|Hu Jintao]]
#[[:w:Zeng Qinghong|Zeng Qing]]
#[[:w:Wang Weilin|Wang Weilin (Tank Man)]]
#[[:w:Li Peng|Li Peng]]
#[[:w:Tiananmen Square protests of 1989|Tiananmen Square Incident]]
#[[:w:Zhou Yongkang|Zhou Yongkang]]
#[[:w:Wu'erkaixi|Wu'erkaixi (June 4 leader)]]

The researchers propose to name this phenomenon the "gateway effect", a "mechanism through which repression can backfire inadvertently, without political or strategic motivation",<ref name="Hobbs2018" /> because it incentivizes people to learn how to evade censorship and thus "have more, not less, access to information and begin engaging in conversations, social media sites, and networks that have long been off-limits to them."<ref name="Hobbs2018" /> They distinguish it from the [[:w:Streisand effect|Streisand effect]], where individuals specifically seek out information that is being hidden.

The second author of the study, Margaret Roberts, is also the author of ''Censored: Distraction and Diversion Inside China's Great Firewall'' (Princeton University Press, 2018; print ISBN 978-0-691-17886-8, e-book ISBN 978-1-400-89005-7).

====Marketing, social media, and Wikipedia====
:''<small>Reviewed by [[en:User:User:Barbara (WVS)|Barbara Page]]</small>''
This study was able to "characterize" the interests of Wikipedia editors and the editors' social media activity on Twitter to facilitate:
[[File:A serviceman accesses social media channels using a smart phone, outside MOD Main Building in London MOD 45156045.jpg|thumb|right|alt=Photograph of person's left hand holding a smartphone that is accessing social media|A marriage between editor editing topics and Twitter (and possibly Facebook) will result in targeted marketing tailored just for you!]]{{Quotebox|[...] building rich user profiles, which can be conveniently used in order to provide personalized contents and offers." and "[...], i.e., the detection of the user's core interests and, therefore, allows for product and service recommendations far more tailored than those stemming from other (usually) extemporary actions on the Internet, like flight ticket purchases and hotel reservations. In this light, it is important to notice that such a profiling potential associated to social login remains nowadays largely unused and enabling its exploitation is one of the main goals of the present work.<ref name="Torrero2018">{{Cite arXiv|last1=Torrero|first1=Christian|last2=Caprini|first2=Carlo|last3=Miorandi|first3=Daniele|date=April 9, 2018|title=A Wikipedia-based approach to profiling activities on social media|arxiv=1804.02245v2|class=cs.IR}}&nbsp;{{free access}}</ref>}}

=====Case studies in the appropriation of ORES=====
From the [[mw:Wikimedia_Research/Showcase#May_2018|announcement]] (by [[mw:User:Halfak (WMF)|Aaron Halfaker]]):
[[File:ORES appropriation and reflection (Research Showcase, May 2018).pdf|thumb|alt=PDF of "ORES appropriation and reflection" with first page depicted|Presentation slides about the use of the ORES platform ([https://www.youtube.com/watch?v=t7cHxlGgEt4 video])]]
{{Quotebox|[[mw:ORES|ORES]] is an open, transparent, and auditable machine prediction platform for Wikipedians to help them do their work. It's currently used in 33 different Wikimedia projects to measure the quality of content, detect vandalism, recommend changes to articles, and to identify good faith newcomers. The primary way that Wikipedians use ORES' predictions is through the tools developed by volunteers. These javascript gadgets, MediaWiki extensions, and web-based tools make up a complex ecosystem of Wikipedian processes – encoded into software.}}
The presentation covered "three key tools that Wikipedians have developed that make use of ORES": Wikidata's damage detection models, exposed through Recent Changes; Spanish Wikipedia's PatruBOT; and WikiEdu tools from [[en:User:Ragesoss|User:Ragesoss]] that incorporate article quality models.

The first problem area of managing accessibility and anonymity contrasts the handling of the technologically available records of activities, disclosures of personal information, and the legal obligations to credit authorship with the authors' right to work anonymously and the need to shield their identity. The second area confronts the contingent addressability of editors with the demand to assure and maintain informed consent."
