Texcavator enables a researcher to use full-text search on the newspaper archive of the Dutch Royal Library. On top of that, it allows for visualizations like word clouds, time lines and heat maps. It also provides services to enhance your search experience like filtering, stopword removal, normalization and stemming. Texcavator also gives access to ShiCo (Shifting Concepts), developed by Carlos Martinez Ortiz (NL eScience Center).ShiCo is a tool for visualizing time shifting concepts. We refer to a concept as the set of words which are related to a given seed word. ShiCo uses a set of semantic models (word2vec) spanning a number of years to explore how concepts change over time -- words related to a given concept at time t=0 may differ from the words related to the same concept at time t=n . Texcavator originated from the earlier text mining applications WAHSP and BiLand. During the Translantis project, the application was renamed to Texcavator and further developed by the UvA (Fons Laan). In May 2014, development was taken over by the Netherlands eScience Center (Janneke van der Zwaan). From April 2015 onwards, Texcavator was developed at the Digital Humanities lab of Utrecht University (Julian Gonggrijp and Martijn van der Klis). ShiCo was created in cooperation with the NL eScience Center (Carlos Martinez Ortiz).
