Problems with Browsing Semantics

4



Interconnected metadataKeyword search is not enough.

Still not everyone knows how to use it.

4





Unstructured metadataFaceted navigation is hard to construct.

Concept of the graph is still hard to understand by most people.

Why the Semantic Web is the Web 3.0 ?Semantics are hard.

Tags are easy.

How to improve user experience?

5



Improving the browsing itself is not enough

The whole search process needs to be improved

Adaptive Browsing

Adaptive Browsing

Presenting resultshuman-readable names of concepts

type-specific rendering

limiting information overload with strechtext

Adaptive Browsing




Refining queries in-situeach concept is seed to new query

different actions based on concept type

Collaborative Browsing

16



Nowadays people share: photos, music, links, etc. - why not queries ?

Collaborative filtering solution adapted for sharing browsing experiencebased on Social Semantic Collaborative Filtering service

users can tag/annotate their queriesusers can share queries with their friends

find all co-authors of Decker

Conclusions

MBB enhances browsing experience with: adaptive browsing collaborative browsing

zoomable browsing context

Conclusions



REST API allows to define own user interface

Conclusions




Feature reach solution scored almost as good as state-of-art “basic” browser, Longwell
