    Satirical News Detection and Analysis using Attention Mechanism and Linguistic Features

    Full text link
    Satirical news is considered to be entertainment, but it is potentially deceptive and harmful. Despite the embedded genre in the article, not everyone can recognize the satirical cues and therefore believe the news as true news. We observe that satirical cues are often reflected in certain paragraphs rather than the whole document. Existing works only consider document-level features to detect the satire, which could be limited. We consider paragraph-level linguistic features to unveil the satire by incorporating neural network and attention mechanism. We investigate the difference between paragraph-level features and document-level features, and analyze them on a large satirical news dataset. The evaluation shows that the proposed model detects satirical news effectively and reveals what features are important at which level.Comment: EMNLP 2017, 11 page

    New Zealand's Fiscal Policy Framework: Experience and Evolution

    Get PDF
    Fiscal policy in New Zealand has seen a consolidation of the Government’s position and continuing refinements to the institutional framework and Budget processes. The key institutional change has been the introduction of the Fiscal Responsibility Act 1994. The paper sets out the background to the fiscal policy framework, including fiscal history and various institutional changes in the public sector. This paper is a companion paper to Treasury Working Paper 01/24 by Angela Barnes and Steve Leith. The key elements of the fiscal policy framework are explained and compared to various “fiscal rules” used internationally. The New Zealand framework differs from that used elsewhere, especially in its use of legislated “principles of responsible fiscal management” as opposed to mandatory targets. However, the Fiscal Responsibility Act 1994 does require Governments to set short-term fiscal intentions and long-term fiscal objectives for a range of fiscal aggregates. The paper discusses the experience with the framework including a comparison of fiscal outcomes with fiscal objectives. The New Zealand experience has seen the evolution of specific operational targets (the fiscal provisions) to help improve the consistency of short-term intentions with longer-term fiscal objectives. The paper concludes with a set of challenges facing the framework, both short- and long-term.Fiscal policy, Fiscal Responsibility Act

    A Topic-Agnostic Approach for Identifying Fake News Pages

    Full text link
    Fake news and misinformation have been increasingly used to manipulate popular opinion and influence political processes. To better understand fake news, how they are propagated, and how to counter their effect, it is necessary to first identify them. Recently, approaches have been proposed to automatically classify articles as fake based on their content. An important challenge for these approaches comes from the dynamic nature of news: as new political events are covered, topics and discourse constantly change and thus, a classifier trained using content from articles published at a given time is likely to become ineffective in the future. To address this challenge, we propose a topic-agnostic (TAG) classification strategy that uses linguistic and web-markup features to identify fake news pages. We report experimental results using multiple data sets which show that our approach attains high accuracy in the identification of fake news, even as topics evolve over time.Comment: Accepted for publication in the Companion Proceedings of the 2019 World Wide Web Conference (WWW'19 Companion).

    People on Drugs: Credibility of User Statements in Health Communities

    Full text link
    Online health communities are a valuable source of information for patients and physicians. However, such user-generated resources are often plagued by inaccuracies and misinformation. In this work we propose a method for automatically establishing the credibility of user-generated medical statements and the trustworthiness of their authors by exploiting linguistic cues and distant supervision from expert sources. To this end we introduce a probabilistic graphical model that jointly learns user trustworthiness, statement credibility, and language objectivity. We apply this methodology to the task of extracting rare or unknown side-effects of medical drugs --- this being one of the problems where large scale non-expert data has the potential to complement expert medical knowledge. We show that our method can reliably extract side-effects and filter out false statements, while identifying trustworthy users that are likely to contribute valuable medical information
