A survey on author profiling, deception, and irony detection for the Arabic language

Rosso, Paolo; Rangel-Pardo, Francisco Manuel; Hernandez-Farias, Delia Irazu; Cagnina, Leticia; Zaghouani, Wajdi; Charfi, Anis (Wiley, 2018-04)

[EN] The possibility of knowing people traits on the basis of what they write is a field of growing interest named author profiling. To infer a user's gender, age, native language, language variety, or even when the user ...
An effcient algorithm based on splitting for the time integration of the Schrödinger equation

Blanes Zamora, Sergio; Casas, Fernando; Murua, Ander (Elsevier, 2015-12-15)

We present a practical algorithm based on symplectic splitting methods intended for the numerical integration in time of the Schrödinger equation when the Hamiltonian operator is either time-independent or changes slowly ...
Author Profiling Tracks at FIRE

Rosso, Paolo; Rangel Pardo, Francisco Manuel (Springer, 2020-02-26)

[EN] Benchmarking activities are vital for fostering research and addressing new challenging problems. During the last 10 years of the FIRE initiative we have been involved in the organization of more than ten tracks, with ...
Battle of the Attack Detection Algorithms: Disclosing Cyber Attacks on Water Distribution Networks

Taormina, R.; Galelli, S.; Tippenhauer, N. O.; Salomons, E.; Ostfeld, A.; Eliades, D. G.; Aghashahi, M.; Sundararajan, R.; Pourahmadi, M.; Banks, M. K.; Brentan, Bruno M.; Campbell-Gonzalez, Enrique; Lima, G.; Manzi, D.; Ayala Cabrera, David; Herrera Fernández, Antonio Manuel; Montalvo Arango, Idel; Izquierdo Sebastián, Joaquín (American Society of Civil Engineers, 2018)

[EN] The BATtle of the Attack Detection ALgorithms (BATADAL) is the most recent competition on planning and management of water networks undertaken within the Water Distribution Systems Analysis Symposium. The goal of the ...
Detecting Deceptive Opinions: Intra and Cross-domain Classification using an Efficient Representation

Cagnina, Leticia; Rosso, Paolo (World Scientific, 2017-12)

[EN] Online opinions play an important role for customers and companies because of the increasing use they do to make purchase and business decisions. A consequence of that is the growing tendency to post fake reviews in ...
Efficient numerical integration for N th-order non-autonomous linear differential equations

Bader, Philipp Karl Heinz; Blanes Zamora, Sergio; Casas, Fernando; Ponsoda Miralles, Enrique (Elsevier, 2016-01-01)

We consider the numerical integration of high-order linear non-homogeneous differential equations, written as first order homogeneous linear equations, and using exponential methods. Integrators like Magnus expansions ...
Fine-Grained Analysis of Language Varieties and Demographics

Rangel, Francisco; Rosso, Paolo; Zaghouani, Wajdi; Charfi, Anis (Cambridge University Press, 2020-11)

[EN] The rise of social media empowers people to interact and communicate with anyone anywhere in the world. The possibility of being anonymous avoids censorship and enables freedom of expression. Nevertheless, this anonymity ...
IDAT@FIRE2019: Overview of the Track on Irony Detection in Arabic Tweets

Ghanem, Bilal; Karoui, Jihen; Benamara, Farah; Moriceau, Véronique; Rosso, Paolo (CEUR-WS.org, 2019-12-15)

[EN] This overview paper describes the first shared task on irony detection for the Arabic language. The task consists of a binary classification of tweets as ironic or not using a dataset composed of 5,030 Arabic tweets ...
Numerical Integrators for the Hybrid Monte Carlo Method

Blanes Zamora, Sergio; Casas, Fernando; Sanz-Serna, J. M. (Society for Industrial and Applied Mathematics, 2014)

We construct numerical integrators for Hamiltonian problems that may advantageously replace the standard Verlet time-stepper within Hybrid Monte Carlo and related simulations. Past attempts have often aimed at boosting the ...
Overview of the Track on Author Profiling and Deception Detection in Arabic

Rangel, Francisco; Rosso, Paolo; Charfi, Anis; Zaghouani, Wajdi; Ghanem, Bilal; Sánchez-Junquera, Javier (CEUR-WS.org, 2019-12-15)

[EN] This overview presents the Author Profiling and Deception Detection in Arabic (APDA) shared task at PAN@FIRE 2019. Two have been the main aims of this years task: i) to profile the age, gender and native language of ...
Solving the Schrödinger eigenvalue problem by the imaginary time propagation technique using splitting methods with complex coefficients

Bader, Philipp; Blanes Zamora, Sergio; Casas, Fernando (American Institute of Physics (AIP), 2013-09-28)

The Schrodinger eigenvalue problem is solved with the imaginary time propagation technique. The separability of the Hamiltonian makes the problem suitable for the application of splitting methods. High order fractional ...
