In this presentation I discuss some of the simple and elegant intuitions that have enabled semantic processing in machines, as well as some of the emerging directions in text quality assessment. 

In the semantic processing I have discussed so far, the computer reads numerous textual documents with the objective to learn representations of words, come up with a lexicon of phrases with positive or negative connotation, or learn category instances and relations. A more difficult task for a computer is to understand... 

Word co-occurrence statistics and subjective language have also been successful in antomatically distinguishing implicit comparison, contingency, and temporal discourse relations (Pider et al., 2009). Identification of such relations is not only necessary for semantic processing of text, it is also required for robust assessment of text quality (Pitler and Nenkova, 2008). Finally, statistics on types, length, and distance between verb, noun, and prepositional phrases, as well as probabilities of occurrence and co-occurrence of words, are highly predictive of the perceived quality of summaries (Nenkova et al., 2010). 

The semantic processing of the post-processor is determined by the directives of the operator, by the actual interpretation and, in case of errors by the error handling.
