their most important content and rewriting them in a simpler style. We learn content selection rules from same-topic Wikipedia ar-ticles written in the main encyclopedia and its Simple En-glish variant. We also use the revision histories of Simple Wikipedia articles to learn a quasi-synchronous grammar

The main feature of the free online-encyclopedia Wikipedia is the wiki-tool, which allows viewers to edit the articles directly in the web browser. As a weakness of this openness for example the possibility of manipulation and vandalism cannot be ruled out, so that the quality of any given

A highly remarkable series of exceptionally engineered late classic prehistoric (est. 1250 to 1450 CE) mountain stream fed water management structures found in the Safford Basin of Arizona’s upper Gila Valley. These canal systems can be uniquely characterized by portions of them being literally "hung " on the edges of steep sided, gently sloping mesas formed from remnant Quaternary age bajadas. At places, the hanging structures are as much as 60 meters above their adjacent drainage basins. It appears the highest feasible points on mesas were carefully selected for canal routes. It also seems clear that extreme energy efficiency was a major goal during the canal construction. Two credible reasons for these unique hanging routes is that their slope could be made largely independent of their surrounding terrain. And that much of the construction effort could be efficiently made across, rather than along the canal routes. Thus minimizing any energy loss or water robbing cuts and fills. Twenty six or more hanging canal systems or fragments have been identified to date. The longest canals exceed 9.5 kilometers (6 miles) and the total system

Most of the tweets that users exchange on Twitter make implicit mentions of named-entities, which in turn can be mapped to corresponding Wikipedia articles using proper Entity Linking (EL) techniques. Some of those become trending entities on Twitter due to a long-lasting or a sud-den effect

This paper proposes a general framework, named Autopedia, to generate high-quality wikipedia articles for given concepts in any domains, by automatically selecting the best wikipedia template consisting the sub-topics to organize the article for the input concept. Experimental results on 4, 526

Abstract. This article presents a method of classification of the Wikipedia articles into the taxonomy of OpenCyc. This method utilises several sources of the classification information, namely the Wikipedia category system, the infoboxes attached to the articles, the first sentences

-ships. Using a combination of further techniques, along with an external gazetteer, the candidate entities and relationships are disambiguated and the Wikipedia article pages are modi-fied to include the semantic information provided by the ex-traction process. We successfully extracted location entities

Net synsets to Wikipedia articles. A sample of synsets has been manually annotated with article matches for evaluation purposes. The automatic methods are shown to create mappings with precision of 87.8 % and recall of 46.9%. These mappings can then be used as a basis for enriching WordNet with new relations

In this paper, we examine the connection between article quality, and “primary authorship ” on Wikipedia articles. An editor is said to be a primary author of an article if he or she has made a signif-icant percent of the total edits to that article. Given a set of edits to an article, we define a

Mechanical Turk is useful for generating complex speech resources like conversational speech transcription. In this work, we explore the next step of eliciting narrations of Wikipedia articles to improve accessibility for low-literacy users. This task proves a useful test-bed to implement
