JEnExtrA (Jena Entity Extraction Application)

Social scientists contemporarily explore sophisticated text-mining tools for big data analysis. One class of tools attracting considerable attention is named entity recognizers, which provide the ability to detect social actors and classify them as persons and organizations. However, it remains a technical challenge to automatically disambiguate (who is referred to in a text?) and specify (which demographic characteristics are present?) social actors. JEnExtrA is a reliable and accurate software architecture for social scientists who are interested in automatically detecting, disambiguating, and demographically specifying social actors in big data. The software architecture utilizes the online encyclopedia Wikipedia.
