Conference Paper

The intended sarcasm cannot be understood until the listener observes that the text’s literal meaning violates truthfulness. Consequently, words and meanings play an essential role in specifying sarcasm. Enriched feature extraction techniques were proposed to capture both words and meanings in the contexts. Due to the overlapping features in sarcas...

Figurative language is using words in a way that deviates from the conventional order and meaning in order to ask the reader or listener to understand the meaning by virtue of its relation to some other meaning or concept. It is a rapidly growing area in Natural Language Processing, including the processing of irony, sarcasm, as well as other figur...

Hate Speech (HS) in social media such as Twitter is a complex phenomenon that attracted a significant body of research in the NLP. HS Spreaders (haters) aim to spread HS via social media. In this task, we aim to identify such haters. On one hand, our proposed class-dependent LDSE representation is fed to a linear SVM classifier to identify the hate...

Toxic Spans Detection(TSD) task is defined as highlighting spans that make a text toxic. Many works have been done to classify a given comment or document as toxic or non-toxic. However, none of those proposed models work at the token level. In this paper, we propose a self-attention-based bidirectional gated recurrent unit(BiGRU) with a multi-embe...

Fake news detection on social medial has attracted a huge body of research as one of the most important tasks of social analysis in recent years. In this task, given a Twitter feed, the goal is to identify fake/real news authors or spreaders. We assume fake news authors mostly like to play with the semantic aspect of news rather than trying to add...

Author Attribution (AA) as one of the most important tasks of authorship analysis attracted huge body of research in recent years. In this task, given a document, the goal is to identify its author from a set of known authors and samples of their writings. In PAN 2019 shared tasks, the AA task is expanded in two ways. First, by having documents wri...

Author verification algorithms mainly rely on learning statistical fingerprints of authors. In the other hand, most of the previous algorithms in author masking try to apply changes to the original texts blindly without considering those fingerprints. In this paper, we propose an approach that learns author's fingerprints and uses them to apply dir...

Author Profiling is one of the most important tasks in authorship analysis. In PAN 2019 shared tasks, the gender identification of the author is the main focus. Compared to the previous year the author profiling task is expended by having documents written by bots. In order to tackle this new challenge we propose a two phase approach. In the first...
