我们开发了一个评价指标优选理论，允许学习者从未经分析的表面形式诱导的词汇和语音语法。我们希望对知识的各个方面进行建模，例如说英语的孩子知道khæt的第一部分的愿望是可预测的，说法语的孩子知道table 'table'的最后一个l是可选的，可以删除，而parle 'speak'的最后一个l不能删除。我们表明，我们目前的学习者成功地获得这种知识，更好地装备这样做比其他现有的学习者在文献中。
We develop an evaluation metric for Optimality Theory that allows a learner to induce a lexicon and a phonological grammar from unanalyzed surface forms. We wish to model aspects of knowledge such as the English-speaking child’s knowledge that the aspiration of the first segment of khæt is predictable and the French-speaking child’s knowledge that the final l of table ‘table’ is optional and can be deleted while that of parle ‘speak’ cannot. We show that the learner we present succeeds in obtaining this kind of knowledge and is better equipped to do so than other existing learners in the literature.
