An analysis of queries intended to search information for children

by Sergio Duarte Torres, Djoerd Hiemstra and Pavel Serdyukov. 

The majority of children and teenagers are active users of the Internet for education and entertainment purposes, thus developing children’s abilities to find and understand information is a key in their development as young adults. However, children’sability to use the Internet is severely hampered by the lack of appropriate search tools. Most Information Retrieval (IR) systems are designed for adults: they return information in a form that is unsuitable for children.The aim of this presentation is twofold: (i) introduce the research lines and outcome of the PuppyIR project which is aimed at providing a infrastructure and framework for developing child-focused information service; and (ii) explore the outcome of our research on understanding the search behavior of children in the Internet and provide a brief description of query recommendation mechanisms tailored at young users.

Visual Exploration of Health Information for Children

by Frans van der Sluis, Sergio Duarte Torres, Djoerd Hiemstra, Betsy van Dijk, Frea Kruisinga 

Children experience several difficulties retrieving informa- tion using current Information Retrieval (IR) systems. Particularly, chil- dren struggle to find the right keywords to construct queries given their lack of domain knowledge. This problem is even more critical in the case of the specialized health domain. In this work we present a novel method to address this problem using a cross-media search interface in which the textual data is searched through visual images. This solution aims to solve the recall and recognition problem which is salient for health information, by replacing the need for a vocabulary with the easy task of recognising the different body parts.
