| Abstract | A central problem in grounded language acquisition is learning the correspondences between a rich world state and a stream of text which references that world state. |
| Experiments | 6It is interesting to note that this type of staged training is evocative of language acquisition in children: lexical associations are formed (Model 1) before higher-level discourse structure is learned (Model 3). |
| Introduction | However, this degree of supervision is unrealistic for modeling human language acquisition and can be costly to obtain for building large-scale, broad-coverage language understanding systems. |
| Introduction | A more flexible direction is grounded language acquisition : learning the meaning of sentences in the context of an observed world state. |
