sentences:  The bits in SDRs have semantic meaning, and that meaning is distributed across the bits.The semantic folding theory builds on these SDR properties to propose a new model for language semantics, where words are encoded into word-SDRs and the similarity between terms, sentences, and texts can be calculated with simple distance measures.Likened to a Bayesian network, an HTM comprises a collection of nodes that are arranged in a tree-shaped hierarchy.
