Track description

The tasks consist in estimating the personality traits of users from their handwritten texts and the corresponding transcripts (see the dataset description above). The challenge comprises two phases, development and final phases. For the first phase, the participants should develop their systems using a set of development pairs of handwritten essays (including image and text) from 418 subjects. Each subject has an associated class 1 and 0, corresponding to the presence of a high pole or a low pole of a specific personality trait. The traits correspond to the Big Five personality model used in psychology: Extraversion, Agreeableness, Conscientiousness, Emotional stability, and Openness to experience. Thus, participants will have to develop a classifier to predict the pole of each trait, this classifier should be able to use the information from both modalities (i.e. textual and visual). For the final evaluation phase, an independent set of 293 unlabeled samples will be provided to the participants, who will have to provide predictions using the models trained on development data. The winners of the challenge will be determined with basis on the final phase performance.

The corpus used in this task consists of handwritten Spanish essays from undergraduates Mexican students. For each essay two files are available: a manual transcript of the text and a scan image of the original sheet where the subject hand-wrote the essay. The texts of manual transcriptions have tags to mark some handwritten phenomena namely: <FO:well-written word> (misspelling), <D:description> (drawing), <IN> (insertion of a letter into a word), <MD> (modification of a word, that is a correction of a word), <DL> (elimination of a word), <NS> (when two words were written together; e.g. Iam instead of I am) and, SB (syllabification). Figure 2  below shows a pair of essays with their corresponding image and text. Each essay is labelled with five classes corresponding to five personality trait in the Big Five Model of Personality. The traits are Extraversion, Agreeableness, Conscientiousness, Emotional stability, and Openness to experience. The classes for each trait are 1 and 0 corresponding to the high pole and low pole of each trait, respectively. To assign each label in the dataset we use an instrument named TIPI (Ten Item Personality Inventory), this instrument includes a specific set of norms for each trait.
