Map: all documents of a certain research interest, where from?

Looking for people

• Search all people of the same family name, sort by given names, state everyone with information about life dates and family details. Table

• Name of people who ever were residents of a given place with basic personal information. Table

• Two Persons, when and where did they meet timeline
• All people with a FactGrid account by gender
• search all people of a research project, Labels and Aliases

Looking for documents

• Everything authored or written to N.N.

• The correspondence of N.N. with him/her as sender (right) and recipient (left)

• All documents written by N.N. with corresponding documents. Table

• All documents sent to N.N. with corresponding documents. Table

• All documents mentioning N.N. with corresponding documents. Table

• All documents of a file listed in sequence. Table

• All documents sent from (place) by date. Table

• All documents of a specific archive and research interest by date. Table

Looking for dates

Dates are still a problem with wikibase. The manual input is very sophisticated. You can set the precision of date and you can define the calendar format. The QuickStatements mass input allows a definition of precision with a defining component on each date (for instance "/9" precision year, "/11" precision day...) but regular searches as formulated with the Query Service's Query Helper do not grab these additional details. A 1650 year input is downloaded as a "1 January 1650" value unless you specifically ask for the precision:

• All the members of the "Fruchtbringende Gesellschaft" with dates of birth and statement of exactness

Prevent double listings

Especially important if you are working with the wdt:P2/wdt:P3* switch that can lead to double hits of the same object - the DISTINCT command:

• List of publishers

Grammatically intricate searches

Wikimedia sources

• all Members of "Theodor zum guten Rat" with their respective Wikidata numbers
• All places that have an article on the Ukrainian Wikipedia; link with the respective uk.wp lemma
• All items with a Wikidata equivalent, without humans and localities

Statements with sources

• Member of the Illuminati, state the primary document reference that we have for this statement

Statements with unit information

• inherited sums of money, Lübeck late Middle Ages
• get the silver-equivalent for a computation in Reichsthaler

Get information from connected items

• The graduates of Gotha's Gymnasium Illustre/Ernestinum: their fathers with career information, their mothers and the fathers of the mothers (i.e. maternal grandfathers) with the respective career information — the search is intricate as it goes into related database objects and brings information located there into the table.

Search for specific Qualifiers on a Statement

• All documents authored by J.C.C. Bode, locations and shelf-marks
• All Teachers with begin/ end/ date information
• Authors writing all kind of satires
• Authors writing satire and all its subclasses (you just add /wdt:P3* to pq:P122)
• The people writing all kind of satires (not necessarily authors) (very simple: remove ps:P165 wd:Q23190)

Search for all the Qualifiers on Statements with the same property

• all the qualifiers for the people holding position at the pastorates of the Duchy of Gotha-Anstalt useful when you want to delete a specific qualifier in a batch of items (here the pastorates of the Duchy), because it is not possible to simply delete qualifiers with Quickstatements. You need to delete the statement with all its qualifiers and reinstall it without the qualifier you want to delete.

You already know one related value

• all the lodges of Saint Domingue/Haiti the intricate part is, that the lodges only have information on places, the places have information on the territorial affiliation - we ask for Q176240 (Haiti) as the must have value. The bracket can also have more countries.

Looking for a statement - give it with all the qualifying statements

This search is especially useful if the data model needs to be changed. It searches the database for a particular statement and gives all the instances with the respective qualifying sub-statements:

SELECT * WHERE {
  ?s wdt:P2 wd:Q7.
  ?s p:P266 ?st. # ?st is the the statement node
  ?st ps:P266 ?o. # that simulates the predicate
  ?st ?qualifier ?value. # this is an attribute (a qualifier)
}

Missing Statements

These searches are most practical to see where work has to be done or where one has forgotten to make a certain statement.

• All the items that lack a P2 (instance of) statement (2732 on 26 April 2023)
• All the titles of a specific project, that lack a P66 statement
• All people who do not have a GND number but who receive mail from a person with such a number
• all types of non-literary genres that were not listed in Eckard Rolf's book of 1993, with their present position in Rolf's systematisation

Missing connections

• all family names that are not used (with Wikidata references)

Wildcards

• all people linked to the French city of Renne

State all statements that are made on an item

• State all statements that are made on an item - the respective value has to be set in line 3.

Filters

• Tutorial

• all FactGrid people born between 1700 and 1710 A Filter that selects a time frame
• All members of the strict Observance in Frankfurt's Prefecture A Filter that selects an Item in a qualifying statement

Filter based on strings

Filtering results containing certain strings (texts) can be archieved with `FILTER()`

• Get all item with "CSD" in its labels within the Remove NA Project

SPARQL patterns for reuse

GROUP_CONCAT Bring several values in one cell (to avoid the repetition of lines)

• Table with names of persons mentioned collected in the last cells

Count properties

Get all properties of an item

SELECT ?p ?o WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  wd:Q406029 ?p ?o
 }

count statements per item within a certain project

or within any other property-object relation

 SELECT DISTINCT ?item ?itemLabel ?statementcount WHERE {
   SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
   # change property item relation
   ?item wdt:P131 wd:Q400012 .
   ?item wikibase:statements ?statementcount.
 }

Get popular items

Considering outcoming, incoming and sitelinks as proxys for popularity, one can formulate this query.

E.g. for Lodges:

 SELECT ?item ?itemLabel ?outcoming ?sitelinks ?incoming {
     ?item wdt:P2 wd:Q11211.
     ?item wikibase:statements ?outcoming .
     ?item wikibase:sitelinks ?sitelinks .
        {
        SELECT (count(?s) AS ?incoming) ?item WHERE {
            ?item wdt:P2 wd:Q11211.
            ?s ?p ?item .
            [] wikibase:directClaim ?p 
        } GROUP BY ?item
  }
   SERVICE wikibase:label { bd:serviceParam wikibase:language "en" . }.  
 } ORDER BY DESC (?incoming)

Federated Queries

Federated queries are those that gather data from multiple data sources. Factgrid can request data from Wikidata and DBpedia.

Get Factgrid IDs that don't have a Wikidata QID, but can be found in Wikidata via its Factgrid ID
