Reading through the assignment for Introduction to Information Retrieval I was struck by how many of the basic indexing, posting lists, and tolerant retrieval I had covered in my previous programming work. Given that the details that we have been exposed to in this first reading assignment are likely quite elementary, I am curious to see how complicated these IR systems can become.
One point that was a touch confusing to me in the reading had to do with the permuterm index. I am not entirely clear on how rotating the term in question as mentioned on pages 53 and 54 of IIR helps resolve the wildcard query problem. Any chance we could have this explained a little more clearly in class this week?
