I was quite interested in the readings this week as they touched on subjects with which I am not entirely familiar. The broad discussion of how web search works was quite informative, followed by the Henziger et al. (2002) article discussing in more depth some of the issues surrounding web search. Over the seven years that have passed since the Henziger article was written I wonder if and how some of the issues presented have been resolved and what other problems have cropped up in web search. Specifically, has social media and the increase in the amount of linking changed the landscape of the link-based search results? For instance, do crawlers find social media websites and index the pages therein? How have search companies responded to links generating from social media websites?
I am interested to know how much of this type of material will be covered in the Advanced Topics in Information Retrieval course next semester.
