Abstract This paper links all individuals who spoke in the German Bundestag between 1949 and 2021 to Wikidata, creating a longitudinal dataset that connects parliamentary speech transcripts with structured biographical metadata. We evaluate the coverage, composition, and potential biases of the retrieved properties and statements, with particular attention to gender, professional background, historical legacies, and transnational dimensions such as place of birth, languages, and foreign awards. The results demonstrate both the analytical potential of combining GermaParl with Wikidata and the importance of critically assessing uneven metadata coverage in open knowledge graphs.

1 Introduction The German federal parliament (Bundestag) publishes its plenary proceedings together with a directory of all elected members (so called ‘Stammdaten’).1 This directory provides core biographical metadata, consisting of names, gender, and party affiliation during a member’s term of office. While the records remain limited in their breadth and depth, in combination with the speech transcripts, this information already enables considerable analysis. As studies on populism (Erhard, Hanke, Remer, Falenska, and Heiberger 2025), gender roles (Spieker 2021; Stecker, Müller, Blätte, and Leonhardt 2021), or the political left–right spectrum (Warode 2025) demonstrate, there is considerable analytical potential and sustained scholarly interest in utilizing the Bundestag plenary proceedings with the metadata available. At the same time, the official member directory (‘Stammdaten’) only covers elected representatives. The plenary proceedings, however, include a broader set of speakers, such as members of the federal government, parliamentary state secretaries, and invited guests. In total, over 4,000 people spoke in front of Germany’s parliament. As can be seen in Table 1 only 87.5% of these speakers are elected officials (P39 - member of the German Bundestag). For the other individuals, no consolidated biographical metadata are systematically provided alongside the proceedings. 1 https://www.bundestag.de/services/opendata

Further information about these persons is encoded in various resources, such as DBpedia (cf. Leonhardt and Blätte 2024) and consolidated metadata databases. For instance, Göbel and Munzert (2022) and Herrmann and Döring (2023) have worked on expanding and refining available metadata for parliamentary actors, showing that enriched contextual information substantially broadens the range of possible inquiries. These efforts, however, remain confined to the databases themselves and, to our knowledge, do not yet comprehensively map the parliamentary speech data to the metadata. These databases can be accessed through Wikidata, to which this paper provides the linking. Especially the historical dimension of this data make it paramount to have open resources that can be critically examined. Social and ideological biases in parliaments are well documented. Navarretta and Hansen (2022), for instance, find gendered patterns in the Danish parliament, where women disproportionately engage with social issues and men with economic ones. Schulz (2021) in turn, aims to trace how National Socialist ideology persisted into the parliaments of the early Federal Republic. However, to our knowledge, a systematic evaluation of coverage and potential data biases has so far been lacking, both in the parliamentary source data and in the linked external resources. Here we address this gap. The contribution of this paper is to link every person to Wikidata who spoke in the German Bundestag from 1949 to 2021 (1st to 19th legislative period). On this basis, we assess the scope, composition, and coverage of additional metadata that can be retrieved through this linkage. To match the conference theme ‘Linking Europe’, we also investigate place of birth, languages spoken, and awards given by foreign entities/countries. We hope to give some pointers at research directions to use this data to e.g., correlate the language of the speeches with prosopographical information. The basis of the project consists of two primary data sources: GermaParl and Wikidata. For the Bundestag proceedings we rely on the GermaParl corpus (Blätte and Blessing 2018; Blätte, Rakers, and Leonhardt 2022), which provides a machine-readable (TEI P5) and annotated version of the plenary protocols (featuring i.a., speaker turns, interjections and party affiliation from the Stammdaten directory). GermaParl is currently being integrated into the larger ParlaMINT corpus (Erjavec et al. 2025). As part of this migration, the GermaParl team is drawing on Wikidata for person metadata – in particular for non-MP speakers’ sex and identifiers (Leonhardt and Blätte 2026) – which is narrower than the coverage pursued here. On the other hand, Wikidata serves as an open, collaboratively curated knowledge base containing structured biographical and contextual information on public figures, including politicians, and references to other authoritative resources like the GND (the Integrated Authority File; for which coverage is almost exhaustive as can be seen below), making it feasible to then further map to the resources of Göbel and Munzert (2022) and Leonhardt and Blätte (2024); Leonhardt and Blätte (2026) down the line.

2 Matching and Metadata Extraction From the GermaParl corpus, we extract all annotated speakers and their associated party affiliations. In total, the dataset contains 4,325 unique speakers. The dataset is available through the Open Science Framework.2 2 https://osf.io/5s3nc/

To assign unique Wikidata identifiers to all recorded speakers, we implement a four-step matching procedure: 1. Name and party match: For each speaker, Wikidata is queried for individuals identified as members of the Bundestag with the corresponding name and party affiliation. 2. Name-only match (restricted to Bundestag members): If no match is found, we query for members of the Bundestag with the same name, irrespective of party affiliation. 3. General name match: If this step also yields no result, Wikidata is queried for any person with the given name. 4. In cases where multiple matches are returned, the correct identifier is determined manually. Manual verification is likewise conducted when no automatic match can be identified. Once identifiers are established, we retrieve all available Wikidata predicates and then statements (predicate-object) associated with each speaker through the Wikidata query service. Table 1 shows the properties with at least 1% coverage and Table 2 the statements with at least 1% coverage (see below in the appendix). These tables already give us a general overview and then we can derive specific dimensions of interest through filtering.

Properties

The coverage of properties (Table 1) shows that Wikidata is almost complete for the (4,325) Bundestag/parliamentary speakers in terms of their ‘core profile’: Basic characteristics such as gender, instance of, date of birth, languages, occupation, and key political information (party, offices/positions) are predominantly at ∼98–100%, and authority IDs (especially GND/VIAF) are also very strongly represented – which suggests that Wikidata is curated through these resources. In contrast, CV and provenance fields such as ‘educated at’ (∼24%) or the official Bundestag biography link (∼44%) are significantly weaker, which means that the data collection is optimized for identity/roles rather than complete CVs; media and Commons data (image/Commons category) are only around half complete. The historical nature of the population is also important: at least 51% of the people recorded already have a date of death (P570) and are therefore deceased, and 348 people have a NSDAP membership number (P2298), which indicates substantial personal overlap with the period 1925–1945, which now opens this data for research questions about influences of the Nazi Regime in the Bundestag (Schulz 2021).

Statements

The coverage of statements (Table 2) shows that gender is systematically recorded; the historical skew (∼79.4% male, ∼20.6% female) reflects male-dominated early parliaments. Looking at the speeches, we find that women’s share of speeches rises from 5% in the first legislative period to nearly 40% in the 18th (Figure 1).

Figure 1: Proportion of speeches given by women across legislative periods (LP 1–19).

Work location data capture the institutional shift from Bonn (∼64.6%) to Berlin (∼21.4%) after reunification, though Berlin appears under-recorded; additional sparse locations likely reflect prior state-level careers. Political affiliation appears both as party membership (P102: SPD 34.0%, CDU 32.7%, FDP 11.8%, CSU 7.5%, Greens 5.9%, Left 3.6%, AfD 2.1%) and parliamentary group (P1416: CDU 34.5%, SPD 29.4%, FDP 9.4%). Doctorates (4.4%) slightly exceed general population levels ( 2% with historical fluctuations), indicating modest overrepresentation without academic elitism. Legal and political professions dominate occupations (P106), with lawyers, economists, teachers, and civil servants prevalent. The increasing use of “politician” over time signals professionalization. While P106 records formal job titles, field of work (P101) captures broader topics/policy areas and is sparsely populated. Finally, entries such as Nazi Party membership (369; ∼8.5%),3 SA/SS affiliations, World War participation, and citizenships like the GDR or German Reich indicate the complex historical trajectories of these political figures. 3.3

Relationship to Europe

Place of birth (Table 3) is dominated by major German cities but includes now Polish cities such as Wrocław (29), Szczecin (12), Gdańsk (9), and Katowice (6). Their presence in the dataset likely reflects the forced migration of Germans from Silesia and other eastern territories after WWII, showing how geopolitical border shifts are encoded in this biographical data. 3 Distinct from NSDAP membership number seen above.

Language data (Table 4) is limited: around 15% speakers do not have German as their native language. English (as a language that is expected to be widely spoken) appears in only 1%, likely due to incomplete Wikidata recording. Other languages (Turkish, Polish, Russian, French) occur in small shares but are probably under-reported as well. Awards are predominantly German but include a notable number of Austrian distinctions and some from Finland and Italy, indicating recognition beyond the national level that reflects German–Austrian ties as well as German war-time alliances.

4 Conclusion In this paper, we demonstrate that systematically linking all Bundestag speakers from 1949 to 2021 to Wikidata yields high coverage for core biographical and political attributes, while revealing clear gaps in more detailed career and contextual information. The enriched metadata will allow us to trace long-term developments such as gender balance, professionalization, regime legacies, and transnational entanglements, but they also expose structural biases and uneven documentation within both parliamentary and Wikidata sources. Future research can build on this linkage to connect speech content with prosopographical characteristics, investigate historical continuities and ruptures, and critically assess how political actors are represented in open knowledge graphs.
