The Workshop on Computational Personality Recognition 2014 is a challenge-based shared task at its second edition and will be held in conjunction to ACMMM on novemebr 7. The main goals of the workshop is to define the state-of-the-art and release data/tools for a standard evaluation of computational personality recognition. Organizers warmly invite contributors working in
Personality Recognition
Data Mining, 
Computational Psychology, 
Natural Language Processing, 
Social Network Analysis, 
Sentiment Analysis,
Opinion Mining,
Mood Detection, 
Deception Detection, 
Information Extraction, 
Human-Computer Interaction, 
Authorship Attribution,
and other related areas,
to submit papers and participate to the competition.
Task organizers will provide an introductory paper to summarize the results and describe the task. The results of the workshop will be available to the public. 

Organizers will provide two gold standard labelled datasets and one evaluation tool.
 we fixed a bug in the class labels of both datasets on May 9, please download the data split, the Mobile Personality dataset and the Evaluation tool again for the correct class labels.
The  shared task is structured in two tracks: one open track and two competitions. 
  • Track 1a: competition on multimodal personality recognition. Contributors are required to use the Youtube personality dataset or the Mobile personality dataset to: 
    1) develop their own system for personality type classification, that generates the predictions in the format required by the evaluation tool; 
    2) submit a short paper (max. 4 pages, including references) indicating "multimodal personality recognition" in the keywords, and reporting all the information about features, resources and techniques used in the experiments. 
    3) report predictions file while submitting the paper. 
  • Track 1b: competition on personality recognition from text. Contributors are required to use only the text transcriptions from the Youtube personality dataset to: 
    1) develop their own system for personality type classification, that generates the predictions in the format required by the evaluation tool; 
    2) submit a short paper (max. 4 pages, including references) indicating "personality recognition from text" in the keywords, and reporting all the information about features, resources and techniques used in the experiments. 
    3) report predictions file while submitting the paper. 
  • Track 2: open shared task. Contributors are required to: 
    use at least one of the datasets provided by the organizers; 
    2) submit a short paper (max. 4 pages, including references) indicating "personality shared task" in the keywords, and discussing their results. Contributors are allowed to use any other corpus or resource, including the ones released in the previous edition of the workshop, to provide useful comparisons between personality recognition and other research fields.
Organizers warmly invite contributors working in Personality Recognition to test their systems on the datasets released. Other researchers or teams that wish to use the datasets for the tasks listed above are more than welcome. Contributors are allowed to participate to more than one task.
Papers must be short (max 4 pages, including references), formatted according to the ACMMM14 templates, anonymous, and delivered via easychair no later than July 8, 2014.
The Programme committee will evaluate and select the papers for publication on the basis of 1) performance, 2) clarity, 3) correctness, 4) meaningful comparison, 5) significance of the results, 6) soundness and replicability. Negative results will be considered as important as positive results.
Selected papers will be published in the workshop proceedings and will be presented as posters at the workshop. 
The best papers could be invited to submit an extended version for a journal special issue in personality recognition.

The organizers of the WCPR14 are:

Computational Linguist at the University of Trento, Italy. He works in Personality Recognition, Text mining, NLP, Social Network Analysis. He got the PhD in Cognitive and brain sciences - Language Interaction and Computation at CIMeC, university of Trento. He developed a system for domain adaptation in personality recognition from text, and produced dataset annotated with personality from Facebook and Twitter. He is the organizer of the first Workshop on Computational Personality Recognition

He is a researcher at Fondazione Bruno Kessler (FBK) and affiliate researcher at MIT Media Lab. From January 2014, he lead the Mobile and Social Computing Lab at FBK.
