Automatic helpfulness prediction aims to prioritize online product reviews by quality. Existing methods have combined review content and star ratings for automatic helpfulness prediction. However, the relationship between review content and star ratings is not explicitly captured, which limits the capability of rating information in influencing review content. This paper proposes a deep neural architecture to learn the explicit content-rating interaction (ECRI) for automatic helpfulness prediction. Specifically, ECRI explores two methods to interact review content with star ratings and adaptively specify the amount of rating information needed by review content. ECRI is evaluated against state-of-the-art methods on six real-world domains of the Amazon 5-core dataset. Experimental results demonstrate that exploiting the explicit content-rating interaction improves automatic helpfulness prediction. The source code of ECRI can be obtained from https://github.com/ tokawah/ECRI.

The travel notes contain a wealth of tourists' behavior information, which provides a new way to study tourists' preferences. How to mine the text of online travel notes accurately and efficiently has become the key to research tourists' preferences. In this paper, the theory and technology of text mining were introduced into the research of tourists' preference through a large number of online travel notes accumulated on the Internet. The main research work of this paper was as follows: (1) The tourists' preference model was constructed by complex network method; (2) The travel notes data of Sanya tourists as an example was crawled and analyzed. In this paper, the theory of network travel data and text mining is introduced into the study of tourists' preferences, which not only improves the data quality of traditional preference research field, but also provides a new method for mastering tourists' preferences more accurately.
