Megalithic monuments in the otherworldly Orkney Islands remain a fundamental part of the landscape. Sheep linger at the Stones of Stenness, the remnants of a ceremonial circle. The Stones of Stenness, a brood of lichen-encrusted megaliths in the far north of the British Isles, could be mistaken for a latter-day work of land art, one with ominous overtones. The stones stand between two lochs on the largest of the Orkney Islands, off the northeastern tip of mainland Scotland. Three colossal planks of sandstone, ranging in height from fifteen feet nine inches to eighteen feet eight inches, rise from the grass, along with a smaller stone that has the bent shape of a boomerang. In contrast to the rectilinear blocks at Stonehenge, the Stenness megaliths are thin slabs with angled upper edges, like upside-down guillotine blades. Remnants of a ceremonial circle, they are placed twenty or more feet apart, creating a chasm of negative space. The monoliths in "2001: A Space Odyssey" inevitably come to mind. Given that the stones were erected five thousand years ago by a culture that left no trace of its belief system, it is unwise to project modern aesthetics onto them. Still, they can be seen only with living eyes. During a recent visit to Orkney, I kept returning to Stenness, at all hours and in all weather. On drizzly days, with skies hanging low, the stones resemble ladders to nowhere. In bright sun, hidden colors emerge: streaks of blue against gray; white and green spatters of lichen; yellowish stains indicating the presence of limonite, an iron ore. Pockmarks and brittle edges show the abrading action of millennia of wind and rain. I watched as tourists approached the stones and hesitantly touched them, as if afraid. When I put my own hands on the rock, I felt no obvious emanations, though I did not feel nothing. One evening, I leaned on a fence as the sun went down, the horizon glowing orange against a cobalt sky.

Improving factual consistency in abstractive summarization has been a focus of current research. One promising approach is the post-editing method. However, previous works have yet to make sufficient use of factual factors in summaries and suffers from the negative effect of the training datasets. In this paper, we first propose a novel factual error correction model FactCloze based on a conditional-generation cloze task. FactCloze can construct the causality among factual factors while being able to determine whether the blank can be answered or not. Then, we propose a data distillation method to generate a more faithful summarization dataset SummDSC via multiple-dimensional evaluation. We experimentally validate the effectiveness of our approach, which leads to an improvement in multiple factual consistency metrics compared to baselines.

If you were Scotland and heading for independence with a vote in the British Isles in 2014 or beyond, which currency would you choose for Scotland's long term prosperity, - institutional-wise, especially (e.g. "Like many Scots, I can clearly distinguish between independence and nationalism, and I certainly wouldn't be voting for nationalism, certainly not for tartan-la-la. Really I'd want a yes vote, then a bloodless coup the next morning, before there were any flags or triumphalism."

The mystique of the ancient stone circle of Stonehenge has long stoked people's imaginations. Theories as to what the Neolithic monument was used for include everything from a burial site to a place of healing. But a team of Australian researchers believes that the bluestone circle and similar formations of standing stones in the UK may actually have been built to track the movements of the sun, moon and stars thousands of years ago. They found strong alignments between the placement and orientation of the stones with the paths of the sun and moon and other features in their surroundings. Experts believe the analysis provides the first evidence to support theories that stone circles were used to measure or track the movement of heavenly bodies.
