摘要: A content recommendation system and method are provided in which content semantic topic analysis, user interest identification and per interest recommendations are used to deliver relevant and diversified content recommendations to the user. Semantic topic analysis is used to infer underlying topics in content items; for each content item, a topic distribution vector is derived with components that represent relevance of the content item to specific underlying topics. A user's long term and short term user interests are identified using the user's browsing history. Long term user interest(s) can be obtained by a weighted aggregation of topic distribution vectors of content items the user accessed. Short term interest can be represented by the topic distribution vector corresponding to a current content item. Using identified user's interests, relevant content items are selected for recommendations for the user.

摘要: A process for generating social recommendations is provided. For each user, a user profile index is accessed to determine reading interests of the user. Further, relevance matching is performed to determine matching users having at least one publishing interest that is relevant to the reading interests of the user. Next, the matching users are ranked. Based on the ranking, one or more top ranked matching user(s) are determined. Additionally, a social recommendation for each of the top ranked matching user(s) is enabled to be made to the user.
