A method and system for intelligent guided shopping. The system includes a computing device. The computing device has a processor and a storage device storing computer executable code. The computer executable code, when executed at the processor, is configured to provide inference models based on user search data. Each of the inference models includes nodes and edges between the nodes. Each of the edges pointing from a first node to a second node is characterized with a probability value. The probability value represents a probability of searching a second keyword corresponding to the second node after searching a first keyword corresponding to the first node.

System and method for intelligent guided shopping

A method and system for generating an answer to a question. The system includes a computing device. The computing device has a processor and a storage device storing computer executable code. The computer executable code, when executed at the processor, is configured to: receive the question inputted by a user regarding a product; extract target answers from a question-answer (QA) knowledge base using the question to form an answer set; extract user comments regarding the product from a comment database to form a comment set; cluster keywords in the answer set to obtain cluster centers; filter the answer set and the comment set using the cluster centers to obtain answer subset and comment subset; and generate the answer to the question from the comment subset, wherein the answer is selected from the comment subset and has high sentence similarity to sentences in the answer subset.
