PHEME: A Social Media Lie Detector

2/27/2014

On February 27, 2014 the following post came across Willard McCarty's Humanist Discussion Group. With its reference to cutting edge social media research in the PHEME project founded in January 2014, combined with the literary quotation on gossip from the Roman poet Ovid's Metamorphosesthis was one of McCarty's characteristically wise posts. It is quoted in full:

        Subject: a social media lie detector?

Two researchers from the Institute of Psychiatry, King's College London, are part of an EU project, PHEME, which aims automatically to detect four types of online rumours (speculation, controversy, misinformation, and disinformation) and to model their spread. "With partners from seven different countries, the project will combine big data analytics with advanced linguistic and visual methods. The results will be suitable for direct application in medical information systems and digital journalism." I note in particular the qualifying statement that,

Indeed. Ovid would, I think, be amused:

> tota fremit vocesque refert iteratque quod audit;
> nulla quies intus nullaque silentia parte,
> nec tamen est clamor, sed parvae murmura vocis,
> qualia de pelagi, siquis procul audiat, undis
> esse solent, qualemve sonum, cum Iuppiter atras
> increpuit nubes, extrema tonitrua reddunt.
> atria turba tenet: veniunt, leve vulgus, euntque
> mixtaque cum veris passim commenta vagantur
> milia rumorum confusaque verba volutant;
> e quibus hi vacuas inplent sermonibus aures,
> hi narrata ferunt alio, mensuraque ficti
> crescit, et auditis aliquid novus adicit auctor.
> illic Credulitas, illic temerarius Error
> vanaque Laetitia est consternatique Timores
> Seditioque recens dubioque auctore Susurri;
> ipsa, quid in caelo rerum pelagoque geratur
> et tellure, videt totumque inquirit in orbem.

> in heaven, on sea and land, and searches throughout the world for
> news.
