Different entities with the same name can be difficult to distinguish. Handling confusing entity mentions is a crucial skill for language models (LMs). For example, given the question "Where was Michael Jordan educated?" and a set of documents discussing different people named Michael Jordan, can LMs distinguish entity mentions to generate a cohesive answer to the question? To test this ability, we introduce a new benchmark, AmbigDocs. By leveraging Wikipedia's disambiguation pages, we identify a set of documents, belonging to different entities who share an ambiguous name. From these documents, we generate questions containing an ambiguous name and their corresponding sets of answers. Our analysis reveals that current state-of-the-art models often yield ambiguous answers or incorrectly merge information belonging to different entities. We establish an ontology categorizing four types of incomplete answers and automatic evaluation metrics to identify such categories. We lay the foundation for future work on reasoning across multiple documents with ambiguous entities.

As the development of the encoder-decoder architecture, researchers are able to study the text generation tasks with broader types of data. Among them, KB-to-text aims at converting a set of knowledge triples into human readable sentences. In the original setting, the task assumes that the input triples and the text are exactly aligned in the perspective of the embodied knowledge/information. In this paper, we extend this setting and explore how to facilitate the trained model to generate more informative text, namely, containing more information about the triple entities but not conveyed by the input triples. To solve this problem, we propose a novel memory augmented generator that employs a memory network to memorize the useful knowledge learned during the training and utilizes such information together with the input triples to generate text in the operational or testing phase. We derive a dataset from WebNLG for our new setting and conduct extensive experiments to investigate the effectiveness of our model as well as uncover the intrinsic characteristics of the setting.

GL Robotics, an advanced technology business, is offering robotic lawnmowers for sale. Obviously, the lawnmower operates on its own and can operate from three to seven hours a day in the yard, so your grass will stay looking sharp at all times. And if you're wondering, the lawnmower is very quiet you can have the lawnmower programmed to run at night while you're at work or sleeping. Owner Laurie Summerlin says not only is it a timesaver but it has other perks as well. "It's very good for the environment it doesn't need gas or oil its a rechargeable battery, so you don't have the carbon footprint and the emission. A lawnmower actually uses as much carbon footprint as 11 cars for the same amount of time, so its good for the environment in that way. Its also very good for the grass it cuts a small amount for each day and it doesn't stress the grass," Summerlin said.
