Learning to Rank Academic Experts
Catarina Moreira,

Abstract:
O problema de procura de peritos é um problema de recuperação de informação que tem vindo a receber bastante interesse por parte da comunidade científica nos últimos anos. No entanto, o actual estado da arte carece de boas abordagens para combinar diferentes fontes de evidência de uma forma óptima. Este trabalho explora o uso de métodos baseados em Learning to Rank como uma boa abordagem para combinar múltiplos estimadores de relevância numa maneira óptima. Estes estimadores são derivados de conteúdos textuais, de estruturas em grafo representando padrões de citação na comunidade de peritos e de informações baseadas no perfil dos peritos.
Este trabalho também explora a eficácia de abordagens baseadas na agregação de rankings combinando diversas técnicas de fusão de dados.
As experiências efectuadas numa colecção de dados de publicações académicas no campo da engenharia informática confirmam a adequação de ambas as abordagens propostas.
