# Using custom background knowledge

One of the key novelties of autoBOT is the use of triplet-based graph databases as background knowledge (i.e. knowledge graphs). As shown in the examples, when doing the initialization:

    autoBOTLibObj = autoBOTLib.GAlearner(
            train_sequences,  # input sequences
                use_concept_features = True,
            train_targets,  # target space
            memory_storage=
            "./memory",  # tripled base for concept features
            representation_type="neurosymbolic")  # or symbolic or neural

There is a dedicated parameter called memory_storage, which is a path that links to a list of files that contain triplets. You can use one or more gzipped tsv files! Example below.

>     schlau\tantonym\tdumm
>     schlau\tantonym\tnaiv
>     schlau\tantonym\ttrottelig
>     schlau\tantonym\tunwissend
>     schlauerweise\tantonym\tblöderweise
>     schlauerweise\tantonym\tdum

The databases are simple tab-separated subject-predicate-object triplets. The files need to be Gzipped (there can be more in the memory folder!).
