Is Mail The Next Frontier In Search And Data Mining?
Yoelle Maarek · 2016
The nature of Web mail traffic has significantly evolved in the last two decades, and consequently the behavior of Web mail users has also changed. For instance a recent study conducted by Yahoo Labs showed that today 90% of Web mail traffic is machine-generated. This partly explains why email traffic continues to grow even if a significant amount of personal communications has moved towards social media. Most users today are receiving in their inbox important invoices, receipts, and travel itineraries, together with non-malicious junk mail such as hotel newsletters or shopping promotions that could safely ignore. This is one of the reasons that a majority of messages remain unread, and many are deleted without being read. In that sense, Web mail has become quite similar to traditional snail mail. In spite of this drastic change in nature, many mail features remain unchanged. While 70% of mail users do not define even a single folder, folders are still predominant in the left trail of many Web mail clients. Mail search results are still mostly ranked by date, which makes the retrieving of older messages extremely challenging. This is even more painful to users, as unlike in Web search, they will know when a relevant previously read message has not been returned.
