Suggestion analysis of opinion data is classifying a given utterance into one of two classes: suggestion and non-suggestion. In this paper, we introduce a new method, called LLMaxent, to cross-domain suggestion classification. LLMaxent is an approach to lifelong machine learning using maximum entropy (Maxent) method. Based on the main idea of lifelong learning, that is retaining the knowledge learned from past tasks and using it to help future learning, we build a classifier can use labeled data in existed domains for suggestion classification in a new domain. The experimental results show that the proposed novel model can improve the performance of cross-domain suggestion classification. This is the first study of lifelong machine learning using Maxent and our method is not only useful for suggestion classification but also for cross-domain text classification in general.
