    Fact Checking in Community Forums

    Full text link
    Community Question Answering (cQA) forums are very popular nowadays, as they represent effective means for communities around particular topics to share information. Unfortunately, this information is not always factual. Thus, here we explore a new dimension in the context of cQA, which has been ignored so far: checking the veracity of answers to particular questions in cQA forums. As this is a new problem, we create a specialized dataset for it. We further propose a novel multi-faceted model, which captures information from the answer content (what is said and how), from the author profile (who says it), from the rest of the community forum (where it is said), and from external authoritative sources of information (external support). Evaluation results show a MAP value of 86.54, which is 21 points absolute above the baseline.Comment: AAAI-2018; Fact-Checking; Veracity; Community-Question Answering; Neural Networks; Distributed Representation

    Public debate in the last two general elections saw significant input from UK fact-checkers. Jen Birks examines the role of fact-checking journalism during the 2017 and 2019 campaigns, and identifies differences in approaches as well as in the policy issues covered

    Revisiting the epistemology of fact-checking

    Full text link
    Joseph E. Uscinski and Ryden W. Butler (2013) argue that fact-checking should be condemned to the dustbin of history because the methods fact-checkers use to select statements, consider evidence, and render judgment fail to stand up to the rigors of scientific inquiry and threaten to stifle political debate. However, the premises upon which they build their arguments are flawed. By sampling from multiple ‚Äúfact-checking agencies‚ÄĚ that do not practice fact-checking on a regular basis in a consistent manner, they perpetuate the selection effects they criticize and thus undermine their own position. Furthermore, not only do their arguments suffer from overgeneralization, they fail to offer empirical quantification to support some of their anecdotal criticisms. This rejoinder offers a study demonstrating a high level of consistency in fact-checking and argues that as long as unambiguous practices of deception continue, fact-checking has an important role to play in the United States and around the world

    Computational fact checking from knowledge networks

    Traditional fact checking by expert journalists cannot keep up with the enormous volume of information that is now generated online. Computational fact checking may significantly enhance our ability to evaluate the veracity of dubious information. Here we show that the complexities of human fact checking can be approximated quite well by finding the shortest path between concept nodes under properly defined semantic proximity metrics on knowledge graphs. Framed as a network problem this approach is feasible with efficient computational techniques. We evaluate this approach by examining tens of thousands of claims related to history, entertainment, geography, and biographical information using a public knowledge graph extracted from Wikipedia. Statements independently known to be true consistently receive higher support via our method than do false ones. These findings represent a significant step toward scalable computational fact-checking methods that may one day mitigate the spread of harmful misinformation

    Automated Fact Checking in the News Room

    Fact checking is an essential task in journalism; its importance has been highlighted due to recently increased concerns and efforts in combating misinformation. In this paper, we present an automated fact-checking platform which given a claim, it retrieves relevant textual evidence from a document collection, predicts whether each piece of evidence supports or refutes the claim, and returns a final verdict. We describe the architecture of the system and the user interface, focusing on the choices made to improve its user-friendliness and transparency. We conduct a user study of the fact-checking platform in a journalistic setting: we integrated it with a collection of news articles and provide an evaluation of the platform using feedback from journalists in their workflow. We found that the predictions of our platform were correct 58\% of the time, and 59\% of the returned evidence was relevant

    Fully Automated Fact Checking Using External Sources

    Full text link
    Given the constantly growing proliferation of false claims online in recent years, there has been also a growing research interest in automatically distinguishing false rumors from factually true claims. Here, we propose a general-purpose framework for fully-automatic fact checking using external sources, tapping the potential of the entire Web as a knowledge source to confirm or reject a claim. Our framework uses a deep neural network with LSTM text encoding to combine semantic kernels with task-specific embeddings that encode a claim together with pieces of potentially-relevant text fragments from the Web, taking the source reliability into account. The evaluation results show good performance on two different tasks and datasets: (i) rumor detection and (ii) fact checking of the answers to a question in community question answering forums.Comment: RANLP-201

    The Diffusion of Fact-checking: Understanding the Growth of a Journalistic Innovation

    Get PDF
    How and why is political fact-checking spreading across journalism? The research presented in this report suggests that the challenge of disseminating the practice is significant -- mere proximity does not appear to be sufficient to drive adoption. However, we find that factchecking can be effectively promoted by appealing to the professional values of journalists.Our first study considers whether journalists might emulate their colleagues in emphasizing fact-checking, following the practices of professional peers in the way that other journalistic innovations have disseminated. However, the practice does not appear to diffuse organically within a state press corps. While fact-checking coverage increased dramatically during the 2012 campaign, these effects were concentrated among outlets with dedicated fact-checkers. We find no evidence that fact-checking coverage increased more from 2008 to 2012 among outlets in states with a PolitiFact affiliate than among those in states with no affiliate.However, it is possible to effectively promote fact-checking. In a field experiment during the 2014 campaign, we find that messages promoting the genre as a high-status practice that is consistent with journalistic values significantly increased newspapers' fact-checking coverage versus a control group, while messages emphasizing audience demand for the format did not (yielding a smaller, statistically insignificant increase). These results suggest that efforts to create or extend dedicated fact-checking operations and to train reporters are the most effective way to disseminate the practice of fact-checking. While audience demand is an important part of the business case for the practice, newsrooms appear to respond most to messages emphasizing how fact-checking is consistent with the best practices and highest aspirations of their field

    Journalistic interventions: The structural factors affecting the global emergence of fact-checking

    Full text link
    Since the emergence of FactCheck.org in the United States in 2003, fact-checking interventions have expanded both domestically and globally. The Duke Reporter‚Äôs Lab identified nearly 100 active initiatives around the world in 2016. Building off of previous exploratory work by Amazeen, this research utilizes the framework of critical juncture theory to examine why fact-checking interventions are spreading globally at this point in time. Seen as a professional reform movement in the journalistic community, historical research on reform movements suggests several possible factors influencing the emergence of fact-checking such as a decline in journalism, easy access to technology for the masses, and socio-political strife. This study offers empirical support that fact-checking may be understood as a democracy-building tool that emerges where democratic institutions are perceived to be weak or are under threat and examines similarities between the growth of fact-checking interventions and previous consumer reform movements. As politics increasingly adopts strategies orchestrated by marketing and advertising consultants and agencies ‚Äď exemplified in the Brexit referendum ‚Äď political fact-checking may benefit from examining the path of consumer reform movements. For, before fact-checking can be effective at informing individuals, it must first establish itself within a structural environment

    Journalism is going through difficult times to defend its role as gatekeeper of fake news. Perhaps, itsnext challenge will beto focus on the future communication professionals, today still university students. Promote active methodologies, applicable to the real case in university classrooms, prepare students to detect disinformation, hoaxes and lies, and especially, focus on how to prepare the news by inserting the marks of informative qual-ity (contrast of sources, use of background, contextualization, explanation and interpre-tation of the facts, in addition to an informative language) and combat the risks in a necessary digital scenario
