In 1982, John Irving Tait introduced Scrabble, a computer program designed to efficiently summarize short English texts. It worked by identifying common material within a text using predefined summary templates. These templates condensed the generally accepted information in that type of text, while unexpected fragments remained largely unchanged in the final summary.
Unlike previous systems, Scrabble represented a significant advance by minimizing the possibility of generating misleading summaries. Tait described these errors as hallucinations, referring to distorted interpretations of the original texts. To combat them, the program incorporated three key innovations: a more accurate method for identifying the main themes of the text, the ability to manage multiple themes simultaneously, and an improved mechanism for integrating unexpected material into summaries. Its effectiveness was demonstrated through practical examples, showcasing its ability to preserve the most relevant and surprising information from the original text.
