Lessons Learned

Easy integration of existing technologies

Limitation of some services: e.g: max 500

requests/day for some API

User Interface: important BUT time consuming

Not easy to create and manage the “all in one”

interface

How to ensure an effective navigation of a large

space of interconnected resources

A lot of effort from Semantic Web community04/08/2023 RAMSS'2012, Dublin, Ireland 15

Future Work

Integrate the other media services and media items

Enrich events descriptions with further information

Refine the reconciliation algorithm

Improve the performance of the user interface.

Data exploration: sentiment analysis, ranking, etc.
