Research Summary – Interactive Search for Smartphones
Abstract
In the late 90s, web search has matured into systems that can effectively retrieve and rank documents from the web. In addition to handling huge repositories (the entire web), these systems can also handle an enormous number of concurrent user queries [7]. Despite these amazing feats, the search experience itself has remained relatively unchanged since it first appeared more than 15 years ago. According to the basic approach, a user enters a set of keywords in a search box and documents from the web are ranked and returned accordingly. Geographical search is also very similar in its concept. The major difference is, that documents represent actual physical entities which have locations. These locations are then also used to determine document to keywords relevance. In addition to returning documents, a geographical search typically also depicts the locations associated with these documents, on a map. This traditional approach is well suited for personal computers which are stationary by nature. The rapid growth of smartphone sales is initiating a significant change. Smartphone shipments overtook personal computers for the first time in 2011 [9]. In addition, today more than 50 % of all “local ” searches are done from a mobile device. In 2014, mobile Internet usage is expected to overtake desktop Internet usage [8]. The ubiquitousness of smartphones, which contain a GPS sensor and have a constant (or highly frequent) Internet connection, have opened up a new way to do search. When using a smartphone, search can be done in an interactive manner. This allows a user to provide feedback as she engages the actual physical entities of the search. The reason is that, unlike a personal computer, the smartphone is always present with the user. Such a search can be optimized for achieving a user’s goal rather than merely a single subtask. The benefit is an innovative new interactive search experience that is tailored for smartphones rather than personal computers
