Multilingual MigrationsKB: A Mulitlingual Knowledge Base of Migration related annotated Tweets

Multilingual MigrationskB (MGKB) is a mulitlingual extended version of English MGKB. The tweets geotagged with Geo location from 32 European Countries (Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Iceland, Liechtenstein, Norway, Switzerland, the United Kingdom)  are extracted and filtered by 11 languages (English, French, Finnish, German, Greek, Dutch, Hungarian, Italian, Polish, Spain, Swedish). Metadata information about the tweets, such as Geo information (place name, coordinates, country code) are included. MGKB  contains sentiments, offensive and hate speeches, topics, hashtags, user mentions in RDF format. The schema of MGKB is an extension of TweetsKB for migration related information. Moreover, to associate and represent the potential economic and social factors driving the migration flows, the data from Eurostat  and FIBO ontology was used. To represent multilinguality, the CIDOC Conceptual Reference Model (CIDOC-CRM) is used. The extracted economic indicators, i.e., GDP Growth Rate, Total Unemployment Rate, Youth Unemployment Rate, Long-term Unemployment Rate and Income per househould, are connected with each tweet in RDF using geographical and temporal dimensions. 

For this version, the Multilingual MGKB is delivered separated by year. The extracted topic words are also published.
