a big problem w/ recommender systems is called the cold-start problem. One way this is manifest is when new items enter the system. In one class of recess, collaborative filtering, since the new item doesn't have any interaction history, it will never be recommended. Then in your case where news articles are the items, then you have an extreme case where every single item is cold. Look at a talk from a Dutch group called Blendle at RecSys conf where they talk about these problems. |
