HWxPI: Handwritten texts for Personality Identification. The tasks consist in estimating the personality traits of users from their handwritten texts and the corresponding transcripts (see the dataset description). 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.
More information can be found at our ChaLearn site.
This challenge was generated using chalab.
As described previously, the problem of personality recognition consists in a binary classification problem for each of five traits. Thus, the evaluation of the participants teams will be through standar set-based metrics, such as F-measure, accuracy, and the the ROC AUC measure. The leading evaluation measure for ranking participants is the macro averaged Area Under the ROC Curve:
**Important** Submissions must be formatted in the same way as the sample submission (Files section-> Develpment button): each row in the submission file has predictions for each subject in the same order as they appear in the provided *.data file. Also, the prediction’s order for each row is important, that is, the first column will be consider the answer for EXT (extraversion trait), second column for AGR (Agreeableness trait), third column for CON (Conscientiousness trait), the forth for STA (emotional stability trait) and the fifth column for OPE (Openness trait). Notice that columns are separated by a single blank space. For the submission file, remember the file's name should start with HWxPIs_valid (for the validation partition) and must end with .predict.
Submissions must be submitted before the 2018-04-22 14:30:00+00:00. You may submit 5 submissions every day and 100 in total.
CHALEARN Contest Rules forMultimedia Information Processing for Personality and Social Networks Analysis Contest 2018
Common terms used in these rules:
These are the official rules that govern how the Multimedia Information Processing for Personality and Social Networks Analysis contest promotion will operate. This promotion will be simply referred to as the “contest” or the “challenge” throughout the rest of these rules and may be abbreviated on our website, in our documentation, and other publications as ChaLearn ICPR2018 LAP.
In these rules, “organizers”, “we,” “our,” and “us” refer to CHALEARN and "participant”, “you,” and “yourself” refer to an eligible contest participant.
This is a skill-based contest and chance plays no part in the determination of the winner(s). There are two tracks associated to this contest as described below:
DivFusion track. Builds on the MediaEval Retrieving Diverse Social Images Tasks, which were addressing specifically the diversification of image search results in the context of social media. The task challenges the participants to develop highly effective information fusion techniques. The participants will be provided with several query results, content descriptors and output of various existing diversifications system. They are to employ fusion strategies to refine the retrieval results thus to improve even more the diversification performance of the existing systems. This track reuses the publicly available datasets issued from the 2013-2016 MediaEval Retrieving Diverse Social Images Tasks (i.e., Div400, Div150Cred, Div150Multi, and Div150Adhoc), together with the participant runs. These data consist of hundreds of Flickr image query results (>600 queries, both single- and multi- topic) and include: images (up to 300 images per query), social metadata (e.g., description, number of comments, tags, etc.), descriptors for visual, text, social information (e.g. user tagging credibility), as well as deep learning features, expert annotations for image relevance and diversification (i.e. clustering of images according to the similarity of their content). An example is presented in Figure 1. The data is to be accompanied by 180 participant runs which correspond to the output of image search retrieval diversification techniques (each run contains the diversification of each query from a dataset). These would allow to experiment with various fusion strategies. The winners of the challenge will be determined by their scores on a held out partition of the data set. Cluster recall and related measures will be used to rank participants.
Figure 1. Example of query data to be diversified by the systems: Flickr image results for query “Pingxi Sky Lantern Festival” (first 14 images from 300) and metadata example for one image.

The evaluation of the participants will be through standard metrics, such as F-measure, accuracy, and ROC AUC measure.
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.
Figure 2. Examples of two pairs of essays: image and text, left and right, respectively.

Judging the entries
The organizers will select a panel of judges to judge the entries; all judges will be forbidden to enter the contest and will be experts in causality, statistics, machine learning, computer vision, or a related field, or experts in challenge organization. A list of the judges will be made available upon request. The judges will review all eligible entries received and select three winners for each of the two competition tracks based upon the prediction score on test data. The judges will verify that the winners complied with the rules, including that they documented their method by filling out a fact sheet.
The decisions of these judges are final and binding. The distribution of prizes according to the decisions made by the judges will be made within three (3) months after completion of the last round of the contest. If we do not receive a sufficient number of entries meeting the entry requirements, we may, at our discretion based on the above criteria, not award any or all of the contest prizes below. In the event of a tie between any eligible entries, the tie will be broken by giving preference to the earliest submission, using the time stamp of the submission platform.
