Research
In my current research project my goal is to identify personality from text documents using linguistics methodologies to find latent features, particularly in Spanish Language.
Personality identification from texts
Aplicación web para identificar personalidad, género y edad de usuarios en Twitter
TxPI-u: A resource for Personality Identification of undergraduates
Shared task at ICPR 2018
Other projects my students and I are working on are:
Texts from depressed users: representation features and its possible detection. We analyze English texts of people with and without depression from Reddit in order to describe the language and behavior of people with depression in social media.
Towards modelling depressed blogers: We use a graph-based representation to find depressed bloggers in a early detection fashion.
Finding signs of anorexia and depression in social media users: In this paper (in Spanish) we explore some traditional texts representations to identify mental disorders.
Information of depression in English texts: Web page (in Spanish) that present the result of this analysis.
Influence in social media. Is it possible to identify influence of a user or posts in social media by analyzing the texts and engagements of other participants in the social media platform?
User influence in Twitter: We identify the influence of a Twitter account by means of style and behavior attributes of that account.
Predicting impact of Facebook posts
Corpus Reacción: The data set of almost 14000 posts in Spanish for impact predictions.
Source code plagiarism identification. We represent each source code with features such as the writer style (in the context of code writing and in comments in natural language) as well as structural attributes and the lexicon use in the name of variables.
On the importance of lexicon, structure and style for identifying source code plagiarism
High level features for detecting source code plagiarism across programming languages
Retrieving and classifying instances of source code plagiarism
