Our web application "Textual Analysis Migration" is a first example of how facts on emigrations can be explored. The facts are extracted by computational linguistics processing by CLARIN infrastructure from large corpora. An important aspect is that the results can be visualized in various ways (table view, geographic map view, and personalized view) and keep the reference to the original text position. Thus, the user may assess the quality of individual facts at any time and actively report improvements.

Especially relevant for

• Historians
• Politic scientists
• literary scholars

Staring point:

German texts, which contain migration information. For example, an article in which is mentioned that someone has moved to another country.
