Work on authorship attribution has traditionally focused on long texts. In this work, we tackle the question of whether the author of a very short text can be successfully identified. We use Twitter as an experimental testbed. We introduce the concept of an author’s unique “signature”, and show that such signatures are typical of many authors when writing very short texts. We also present a new...

The authorship attribution literature demonstrates the difficulty to design classifiers overcoming simple strategies such as linear classifiers operating on a number, most frequent, of lexical features such as character trigrams. We claim this comes, at least partially, from the difficulty to efficiently learn the contribution of all features, which leads to either undertraining or overtraining...

Authorship attribution is associated with important applications in forensics and humanities research. A crucial point in this field is to quantify the personal style of writing, ideally in a way that is not affected by changes in topic or genre. In this paper, we present a novel method that enhances authorship attribution effectiveness by introducing a text distortion step before extracting st...

Morality—judging others’ behavior to be right or wrong, as well as behaving in a right or wrong manner towards others—is an essential component of social life. Morality depends critically on our ability to attribute minds to entities that engage in moral actions (towards ourselves and others) and the entities that experience these actions (our own actions and others’). The cognitive capacities ...

When viewing one object move after being struck by another, humans perceive that the action of the first object "caused" the motion of the second, not that the two events occurred independently. Although established as a perceptual and linguistic concept, it is not yet known whether the notion of causality exists as a fundamental, preattentional "Gestalt" that can influence predictive motor pro...

Quantitative authorship attribution refers to the task of identifying the author of a text based on measurable features of the author’s style—a problem that has practical application in areas as diverse as literary scholarship, plagiarism detection, and criminal forensics. Attribution methods generally follow a generative approach, wherein a statistical “profile” is created for a set of candida...
