Speaker: David Arroyo
Saturday 20, 10:00-10:45
Our daily activity is more determined by the way we access cloud services through our smartphones than through our computer. The value chain associated to all these data interfaces and computation modalities is very dependent on the quality of information sources and the trustworthiness of the mechanisms for data coding, decision making and information security.
In this seminar we will explore the design implications for the construction of a misinformation widget guiding users in assessing the trustworthiness of various sources of information. A critical aspect in the design of the widget is the identification of the best news classification tools and methodologies. To achieve this objective, on option is to rely on fact checking platforms and human experts to obtain feedback, which can be extended by leveraging the so- called wisdom of crowds and perform news curation as result of a collaborative effort among users and experts. Expert-based systems are accurate but costly and not scalable, while crowds-based systems can be biased by herding behavior. To overcome these limitations, we can ponder the developing of automatic detection techniques by means of Natural Language Processing (NLP) and more advanced Machine Learning (ML) techniques. Nonetheless, the selection of adequate models and datasets for their tuning and training is itself a challenge. Thus, we explore the option of adopting a so-called “human on the loop” approach, which integrates expert knowledge on fact checking and automatic detection of fake news and misinformation. Specifically, we propose a methodology that leverages fact-checking platforms to perform datasets labeling and the validation of the performance of NLP and ML tools for the automatic classification of information.
