      "@value" : "However, the reliability of a general-purpose KB like Wikidata is an essential requirement to ensure credible (thus high-quality) content: as a support for their trustworthiness, data should be validated against third-party resources. Even though the Wikidata community strongly agrees on the concern, 6 few efforts have been approached towards this direction. The addition of references to external (i.e., non-Wikimedia), authoritative Web sources can be viewed as a form of validation. Consequently, such real-world setting further consolidates the need for an intelligent agent that harvests structured data from raw text and produces e.g., Wikidata statements with reference URLs. Besides the prospective impact on the KB augmentation and quality, the agent would also dramatically shift the burden of manual data addition and curation, by pushing the (intended) fully human-driven flow towards an assisted paradigm, where automatic suggestions of pre-packaged statements just require to be approved or rejected. Figure 1 depicts the current state of the primary sources tool interface for Wikidata editors, which is in active development yet illustrates such future technological directions. Our system already takes part in the process, as it feeds the tool back-end."
