Creating Interaction Database

• writefile ml-get-abstract-general (SPEC) 
  to "ARTICLES" using stdout;
  writefile
    {(#muid:x.#muid, #sentence:x.#sentence,
      #matched:x.#matched, #interaction:y)
    | \x <- process 
              (BioNLP, ["ARTICLES.val"], "") 
            using syscall-co,
      \y <- x.#interactions }
  to "INTERACTIONS" using stdout;
  

• Kleisli accesses MEDLINE and invokes BioNLP to extract interactions

• Kleisli is also used later to express high-level transformations
