Deadline for applications: 16 February 2019
Start date: on or before 1 May 2019
Duration: 12 months
Keywords: natural language processing, commonsense reasoning, vector space embeddings, interpretable machine learning
Applications are invited for a postdoctoral research post at Cardiff University’s School of Computer Science & Informatics in the context of the ERC funded project FLEXILOG. The overall aims of this project are (i) to learn interpretable vector space embeddings (or conceptual spaces) from a variety of structured and unstructured information sources, and (ii) to exploit these embeddings for improving statistical and symbolic inference from imperfect data. More information about FLEXILOG can be found on the project website: http://www.cs.cf.ac.uk/flexilog/
Specifically, the aim of these posts will be to contribute to one or more of the following:
(i) to learn word representations which explicitly capture attributional (e.g. lions are dangerous) and relational (e.g. lions eat zebras) knowledge;
(ii) to develop methods for statistical reasoning from sparse relational data based on vector space representations;
(iii) to develop methods for knowledge base completion based on vector space representations.
The following are some representative recent publications from the FLEXILOG project:
