-Science fiction Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas".
-Science fiction It usually avoids the supernatural, unlike the related genre of fantasy.
-Science fiction Historically, science-fiction stories have had a grounding in actual science, but now this is only expected of hard science fiction.
-Science fiction Science fiction is difficult to define, as it includes a wide range of subgenres and themes.
-Science fiction Hugo Gernsback, who suggested the term "scientifiction" for his "Amazing Stories" magazine, wrote: "By 'scientifiction' I mean the Jules Verne, H. G. Wells and Edgar Allan Poe type of story—a charming romance intermingled with scientific fact and prophetic vision...

 ## Privacy
 
 Our work focuses on models with open-domain conversations wherein speakers may divulge personal interests. We remark that, during data collection, crowdworkers were specifically playing roles with given personality traits, not talking about themselves, and hence not identifying any personal information.

The test and valid sets are split into two sets each: one with overlapping topics with the train set, and one with unseen topics.

 We used the metric `class notok f1`, the f1 scores for the class notok as the validation metric. Recall that `class___notok___f1` is unigram F1 overlap, under a standardized (model-independent) tokenizer.
