Traditionally, although KBs use open world assumption, popular KBs only store positive information, but withhold from taking any stance towards statements\n            <jats:italic>not<\/jats:italic>\n            contained in them. In this demo, we show that storing and presenting\n            <jats:italic>noteworthy<\/jats:italic>\n            negative statements would be important to overcome current limitations in various use cases. In particular, we introduce the\n            <jats:bold>\n              Wiki\n              <jats:italic>neg<\/jats:italic>\n              ata\n            <\/jats:bold>\n            portal, a platform to explore negative statements for Wikidata entities, by implementing a peer-based ranking method for inferring interesting negations in KBs.
