Esaú Villatoro-Tello,Antonio Juárez-González,Hugo Jair Escalante,Manuel Montes-y-Gómez,Luis Villaseñor +4 more
TL;DR: This paper describes the system jointly developed by the Language Technologies Lab from INAOE and the Language and Reasoning Group from UAM for the Sexual Predators Identification task at the PAN 2012, and demonstrates that it is possible to train a classifier to learn those particular terms that turn a chat conversation into a case of online child exploitation.

Early detection of deception and aggressiveness using profile-based representations
Hugo Jair Escalante,Esaú Villatoro-Tello,Sara E. Garza,A. Pastor López-Monroy,Manuel Montes-y-Gómez,Luis Villaseñor-Pineda +5 more
TL;DR: Results reveal that PBRs achieve state of the art performance when using full-length documents, and that the proposed methodology outperforms previous work on early recognition of sexual predators by a considerable margin, while obtaining state-of-the-art performance in aggressive text identification.
INAOE's participation at PAN'13: Author Profiling task Notebook for PAN at CLEF 2013
Adrián Pastor López-Monroy,Manuel Montes-y-Gómez,Hugo Jair Escalante,Luis Villaseñor Pineda,Esaú Villatoro-Tello +4 more
TL;DR: In this paper, a second-order Bag-of-Terms representation for Author Profiling (AP) has been proposed to overcome the sparsity and high dimensionality of document representations and the assumption of total independence between terms in documents.

On the Detection of SOurce COde Re-use
TL;DR: SOCO 2014 as mentioned in this paper focused on the detection of re-used source codes in C/C++ and Java programming languages, and participant systems were asked to annotate several source codes whether or not they represent cases of source code re-use.
