EuroHCIR2013 Work Towards a New Search Interface namely Perspective-Aware Search

Recently an updated version was demoed  in SIGIR 2014:

There are occasions when search results do not satisfy the information need and give a completely undesirable set of results than what the user is looking for. A possible reason for this lies inside the returned documents which contain some perspectives while giving coverage to the topic and this perspective may be observed as bias by the user.
Lets take the following example scenarios:
  • Consider a case where a user wishes to find information about a certain event (say, a bomb attack in a certain region). The search results returned, contain a majority of news reports blaming Islam (its implicit writing style) relating it with terrorism in most of the cases. This prompts the user to explicitly observe how much Islam is related with terrorism in the returned set of search results.
  • Consider another case where a user wishes to find information about roles and rights of women in Islam but the search engine returns articles that contain a tendency of highlighting oppression against women instead of women rights and roles. In this case the user observes a correlation between women and oppression instead of factual position on rights.
In the above cases, the user's information need may lead him towards an explicit investigation of the underlying document collection and he/she may be interested in observing the amount of perspective tendencies in various search results (e.g., news reports). Current search engines do not facilitate this need by highlighting perspectives while displaying the search results. Hence, we propose the concept of "perspective-aware search." The proposed search interface enables the user to explicitly analyze search results with a touch of perspective awareness.

The following presentation contains some screen-shots of the proposed search interface; I will be giving a demo of this system at EuroHCIR Workshop that is co-located with SIGIR2013.

The system is built on top of the WikiMadeEasy API which is an API for mining Wikipedia data and is the output of work I am doing towards my PhD thesis. Feel free to contact me for more details of the API. The full paper describing the system can be found here.
