Let’s start pointing out some key differences: While most dynamics in social media are about sharing opinions and gaining popularity, Wikipedia is about sharing in the sum of all knowledge. Wikipedia’s unique goal and process presents both challenges to applying machine learning techniques used by large social media platforms to identify disinformation and opportunities for new, more human-centered approaches. Let’s start by comparing these two different paradigms. First of all, your social network activity reflects your thoughts and interests, on the other hand, a Wikipedia article is collectively created, or in other words is a commons, without a single owner. Second, the lifecycle on social networks content is very short, but for Wikipedia it is about perennial knowledge. And last, but not least, in social networks you can do – almost – whatever you want respecting a very general set of “terms and conditions” designed by the platform owners, while in Wikipedia there are procedures and policies for writing articles, created by the community, including key points like keeping a neutral point of view and using reliable and verifiable sources.

However, problems for the most popular social networks are related with their business model: they need to allow people to say whatever they want, and – probably the most important part – to show people content that increases their engagement, usually reinforcing their beliefs. Content trustworthiness is not the aim of those companies; they need just to control extreme cases. This filtering process is known as content moderation. And given the huge amount of content they need to moderate, big tech companies are putting a lot of effort and hopes on developing tools based on Machine Learning (a.k.a Artificial Intelligence) to help – and take the lead – on detecting and removing that extreme content.

Misleading information can happen in Wikipedia when edits do not fulfill content policies. This can be on purpose with the intention of deception (disinformation) or it can be accidental (misinformation). Whatever the motivation, the community regulates itself.

Wikipedia can’t have a unique ground-truth, because its aim is to be the sum of all human knowledge, so there is no single point of reference, and moreover, all significant points of view  – supported by reliable sources – needs to be represented. Wikipedia “moderation” is not about the truth, it is about verifiability of content through reliable sources. And the rules don’t come from a unique central authority, they are designed, reviewed and applied by a community of editors, through a well-established deliberation process.

[Verdade Relativa e diferentes perspectivas precisam ser contempladas para uma visão neutra]

In summary, the challenges on fighting disinformation on Wikipedia require dedicated effort that goes beyond addressing the traditional “fact-checking” problem. Differently from Social Networks where algorithms are expected to do the work that no one else is doing, in Wikipedia we need algorithms able to help the current editor’s workflows, implying that our baseline is much more challenging.

Connected Papers: Uma abordagem alternativa para revisão da literatura

Durante um projeto de pesquisa podemos encontrar um artigo que nos identificamos em termos de problema de pesquisa e também de solução. Então surge a vontade de saber como essa área de pesquisa se desenvolveu até chegar a esse ponto ou quais desdobramentos ocorreram a partir dessa solução proposta para identificar o estado da arte nesse tema. Podemos seguir duas abordagens:  realizar uma revisão sistemática usando palavras chaves que melhor caracterizam o tema em bibliotecas digitais de referência para encontrar artigos relacionados ou realizar snowballing ancorado nesse artigo que identificamos previamente, explorando os artigos citados (backward) ou os artigos que o citam (forward)  Mas a ferramenta Connected Papers propõe uma abordagem alternativa para essa busca. O problema inicial é dado um artigo de interesse, precisamos encontrar outros artigos relacionados de "certa forma". Find different methods and approaches to the same subject Track down the state of the art rese...

Aprendizado de Máquina Relacional

 Extraído de -> https://www.lncc.br/~ziviani/papers/Texto-MC1-SBBD2019.pdf   Aprendizado de máquina relacional (AMR) destina-se à criação de modelos estatísticos para dados relacionais (seria o mesmo que dados conectados) , isto é, dados cuja a informação relacional é tão ou mais impor tante que a informação individual (atributos) de cada elemento.    Essa classe de aprendizado tem sido utilizada em diversas aplicações, por exemplo, na extração de informação de dados não estruturados [Zhang et al. 2016] e na modelagem de linguagem natural [Vu et al. 2018].   A adoção de técnicas de aprendizado de máquina relacional em tarefas de comple mentação de grafo de conhecimento se baseia na premissa de existência de regularidades semânticas presentes no mesmo .

Beyond Facts: Online Discourse and Knowledge Graphs A preface to the proceedings of the 1st International Workshop on Knowledge Graphs for Online Discourse Analysis (KnOD 2021, co-located with TheWebConf’21) https://ceur-ws.org/Vol-2877/preface.pdf https://knod2021.wordpress.com/   ABSTRACT Expressing opinions and interacting with others on the Web has led to the production of an abundance of online discourse data, such as claims and viewpoints on controversial topics, their sources and contexts . This data constitutes a valuable source of insights for studies into misinformation spread, bias reinforcement, echo chambers or political agenda setting. While knowledge graphs promise to provide the key to a Web of structured information, they are mainly focused on facts without keeping track of the diversity, connection or temporal evolution of online discourse data. As opposed to facts, claims are inherently more complex. Their interpretation strongly depends on the context and a vari...
