TPDL 2011 Doctoral Consortium

Today the International Conference on Theory and Practice of Digital Libraries 2011 started with tutorials and a Doctoral Consortium that I participate with a talk. The seven talks and discussions on ongoing PhD topics were rather diverse and interesting. I tried to briefly summarize at least some of them.

Luco Colombo started with his work on developing and evaluating eBook reading experience for children. Reading „traditional“ books has been extensively investigated – this is not true for eBooks. Especially children are little involved in eBook studies. Colombo explained how the eBook reading experience is different because it directly involves searching, browsing, sharing, and recommending, among other arguments. A good reading experience results in a „flow state“ where the reading gets positively lost in a book. Colombo’s method is a cooperative inquiry. It is not clear whether and by what eBooks are more engaging to children (age 9-11 in this study) than traditional books – maybe this PhD will show. The following discussion was dominated by the participating mentors Jose Borbinha, Milena Dobreva, Stefan Gradmann and Giuseppina Vullo.

In the second talk Krassimira Ivanova presented her dissertation on (content-based) image retrieval utilizing color models. Image retrieval on art images is difficult because it includes very different aspects (artistic styles, depicted objects etc.). Even aspects of color (contrasts, intensity, diversity, harmony etc.) are manifold – maybe this is why philosophy of color has a long history. Nevertheless Ivanova developed several machine learning methods for this color aspects that can be used for image retrieval. I am not sure whether the resulting APICAS system („Art Painting Image Colour Aesthetics and Semantics“) has been evaluated with a user study. Similar to the first talk, the focus could be improved by more narrowing down and making clear the specific contribution. Finally we had some real discussion, but little time.
