The CogALex-Ⅳ Shared Task on the Lexical Access Problem

摘要

The shared task of the 4th Workshop on Cognitive Aspects of the Lexicon (CogALex-Ⅳ) was devoted to a subtask of the lexical access problem, namely multi-stimulus association. In this task, participants were supposed to determine automatically an expected response based on a number of received stimulus words. We describe here the task definition, the theoretical background, the training and test data sets, and the evaluation procedure used for ranking the participating systems. We also summarize the approaches used and present the results of the evaluation. In conclusion, the outcome of the competition are a number of systems which provide very good solutions to the problem.
