As generated text becomes more commonplace, it is increasingly important to evaluate how well-supported such text is by external knowledge sources. Many approaches for evaluating textual support rely on some method for decomposing text into its individual subclaims which are scored against a trusted reference. We investigate how various methods of claim decomposition -- especially LLM-based methods -- affect the result of an evaluation approach such as the recently proposed FActScore, finding that it is sensitive to the decomposition method used. This sensitivity arises because such metrics attribute overall textual support to the model that generated the text even though error can also come from the metric's decomposition step. To measure decomposition quality, we introduce an adaptation of FActScore, which we call DecompScore. We then propose an LLM-based approach to generating decompositions inspired by Bertrand Russell's theory of logical atomism and neo-Davidsonian semantics and demonstrate its improved decomposition quality over previous methods.

If the world's most famous film directors designed a car, what would it look like? Thanks to artificial intelligence, we now have the answer. A car scrap collection firm based in the UK used DALL-E-2 - an AI platform that creates images based on text inputs - to imagine what cars designed by Wes Anderson, Christopher Nolan, Alfred Hitchcock and James Cameron, among others, would look like. The results show how powerful this particular artificial intelligence system, which was built by OpenAI, can be when given this type of assignment. British-born director Christopher Nolan is recognized for his work on the Batman trilogy as well as films like Interstellar, which explored many quantum physics themes, and the World War II film Dunkirk.

Pendulo Studios' Vertigo begins, just like the 1958 film, with a visual and musical motif of spirals. Round and round they go until you meet author Ed Miller in the worst moment of his life. Ed narrowly survives a car crash, but he loses his wife, Faye and their daughter. Staring down at the wreck of his car in a ravine, Ed suffers a debilitating bout of vertigo, only to relive the suicide of his father shortly after. A little later, you step into the shoes of Dr Julia Lomas, a therapist called in to deal with Ed's vertigo and why he keeps talking about a wife and child whom no one but him seems to recall. While it's called Vertigo, complete with the licence of Hitchcock's name and likeness, the game makes hamfisted references to the director's work.
