Multi Tier Annotation Search

See meertensinstituut.github.io/mtas/ or build and run a Docker image providing a demonstration scenario with indexing and querying of some sample documents.

docker build -t mtas https://raw.githubusercontent.com/meertensinstituut/mtas/master/docker/Dockerfile
docker run -t -i -p 8080:80 --name mtas mtas

This will provide a website on port 8080 on the ip of your docker host with more information.

One of the primary use cases for the system, the Nederlab project, currently¹ provides access, both in terms of metadata and annotated text, to over 15 million items for search and analysis as specified below.

	Total	Mean	Min	Max
Solr index size	1,146 G	49.8 G	268 k	163 G
Solr documents	15,859,099	689,526	201	3,616,544
Words	9,584,448,067	654	1	3,537,883
Annotations	36,486,292,912	2,488	4	23,589,831

Collections are added and updated regularly by adding new cores, replacing cores and/or merging new cores with existing ones. Currently, the data is divided over 23 separate cores. For 14,663,457 of these documents, annotated text varying in size from 1 to over 3.5 million words is included.
