Hugo Pinto's Selected Publications

            Some selected publications. You will find works on game AI, natural language processing and machine learning. Most are in English. For the ones that I am authorized and the conference has already taken place I try to provide a link to the pdf version. To help you decide if you will download the article, I have provided one-line comments that convey relevant information not present in the paper title. If perchance you're interested in the full list of publications, ask me (some additional monographs, posters and conference articles).

Natural Language Processing

  • The Senior Companion Multi-Agent Dialogue System. Hugo Pinto, Yorick Wilks and Roberta Catizone. Proc. of the Seventh International Joint Conference on Autonomous Agents and Multi-Agent Systems (AAMAS08). 2008. A multimodal dialogue system that talks about photographs.

  • Speech-Based Dialogue Systems. Hugo da Silva Corrêa Pinto and Roberta Catizone. AI Game Programming Wisdom 4, Steve Rabin(Ed). Charles River Media. 2008. A tutorial overview of modern spoken dialogue systems, with illustrations from the TRIPS family and the NICE project, and a discussion of the particulars of the games domain.

  • Dialogue Managers. Hugo da Silva Correa Pinto. AI Game Programming Wisdom 4, Steve Rabin(Ed) Charles River Media. 2008. A progressive overview of the main techniques and paradigms of dialogue management (stacks, finite-state machines, frames, inference engines and planners) with focus on their applicability to computer games.

  • Automatic  Creation and Translation of Concept Maps for Computer Science-Related Theses and Dissertations. Ryan Richardson, Eduard Fox, Hugo Pinto and Ben Goertzel. Proceedings of the Concept Map 2006 Conference. PDF.

  • Using Dependency Parsing and Probabilistic Inference to Extract Relationships between Genes, Proteins and Malignancies Implicit Among Multiple Biomedical Research Abstracts. Ben Goertzel, Hugo Pinto, Cassio Pennachin et al. Proceedings of the BioNLP Workshop/HLT-NAACL 2006. PDF

  • NL Comprehension via Integrative AI and Human-Computer Interaction. Goertzel, Ben, Moshe Looks, Michael Ross, Cassio Pennachin and Hugo Pinto (2005) (Available at Ben Goertzel´s site). Describes part of my NLP work at Vetta Technologies. For the AI-oriented reader it is relevant to mention that it is deeply tied to Novamente , an artificial general intelligence architecture, and describes a tool for knowledge entry in the military domain.

Computer Games

This is the only application of behavior networks to character design besides Rhode’s, and the only one in a computer game setting, as far as I know. PDF.
  • An Extended Behavior Network for a Game Agent: Investigating Action Selection Quality and Agent Performance in Unreal Tournament. Pinto, H. and Alvares, L.O. MICAI 2005: Advances in Artificial Intelligence: 4th Mexican International Conference on Artificial Intelligence, Monterrey, Mexico, November 14-18, 2005. Alexander Gelbukh Ed. Springer-Verlag.287-296.  Mature quantitative and qualitative results- if you have just one hour and wanna know quickly what 30% of my thesis is about, go for it. PDF. PPT
  • Designing Autonomous Agents for Computer Games with Extended Behavior Networks: An Investigation of Agent Performance, Character Modeling and Action Selection in Unreal Tournament. Hugo Pinto. M.Sc. Thesis. Universidade Federal do Rio Grande do Sul. Brazil.2005. The presentation has a detailed, step by step coverage of the activation spreading algorithm.
