This book takes advantage of the semantic representation of the AR6 Synthesis Report [1], part of the IPCC Sixth Assessment Report [2]. It wraps around a Wikibase at kg-ipclimatec-reports.wikibase.cloud.
The report links its statements to confidence levels. The following query is for a list of confidence levels, along with the number of statements with that level:
SPARQL sparql/confidenceLevels.rq (run, edit)
PREFIX wdt: <https://kg-ipclimatec-reports.wikibase.cloud/prop/direct/>
PREFIX wd: <https://kg-ipclimatec-reports.wikibase.cloud/entity/>
PREFIX p: <https://kg-ipclimatec-reports.wikibase.cloud/prop/>
PREFIX pq: <https://kg-ipclimatec-reports.wikibase.cloud/prop/qualifier/>
SELECT ?confidence ?confidenceLabel (COUNT(DISTINCT ?statement) AS ?count) WHERE {
?paragraph p:P3 ?statement .
?statement pq:P5 ?confidence .
FILTER(contains(str(?confidence), "https"))
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
} GROUP BY ?confidence ?confidenceLabel
Which gives:
| confidence | count |
| high confidence | 56 |
| medium confidence | 12 |
| very high confidence | 9 |
| low confidence | 1 |
| medium to high confidence | 3 |
This knowledge graph has a number of types used to semantically model the data.
The AR6 Synthesis report is organized as a collection of sections that consist of one or more paragraphs, where each paragraphs cites other parts of the IPCC reports. Each paragraph consists of facts, each with a confidence level (see above). This is explained more in the next section.
This model is captured in the shape expression E1 (see [3]):
