(1) from the information science research object, the information science research object has experienced the traditional literature (mainly books)->; Digital information (mainly brought by the information technology revolution)->; Knowledge (current and future trends).

(2) It seems unreasonable that information science also studies e-commerce.

But if you think about it carefully, the traditional information science research object literature actually contains a wide range of contents, such as information organization, information retrieval, information service and so on. , and the corresponding information organization, information retrieval and information services are now available.

Although e-commerce involves a wide range, most users present the interface of a website. Do you think this interface contains a lot of information? Yes, information science began to study the information organization in e-commerce, mainly studying how to organize information reasonably. Then Americans put forward a concept called "information construction". In fact, information construction mainly studies the organization system, logo system, navigation system and retrieval system of websites. This is very common in e-commerce. Therefore, it has become one of the contents of information science research.

(3) Another thing that can't be ignored is that information science is actually user-oriented, and information services are aimed at users, corresponding to users of e-commerce, mainly for various empirical studies conducted by users, and there are also many papers in this regard.

(4) I suggest you find some information science journals to get a general idea of what e-commerce research involves. Good luck with your second interview.
