This paper describes Seeker, a platform for large-scale text analytics, and SemTag, an application written on the platform to perform automated semantic tagging of large corpora. We apply SemTag to a collection of approximately 264 million web pages, and generate approximately 434 million automatically disambiguated semantic tags, published to the web as a label bureau providing metadata regard...

In 1872, the headwaters of the Yellowstone River and the surrounding forests, canyons and geyser basins were designated the world’s first national park. Since then, most nations of the world, whatever their size, have protected important biological, scenic, geological and historic places. That decision to make Yellowstone a national park set in motion a series of events with unforeseen but fort...

Needs for increased product quality, reduced pollution, and reduced energy and material consumption are driving enhanced process integration. This increases the number of manipulated and measured variables required by the control system to achieve its objectives. This paper addresses the question of whether processes tend to become increasingly more difficult to identify and control as the proc...

We describe lessons learned in developing a program for interactive optimization of large airlift scheduling problems. While for small problems one can create a visualization that both shows a complete solution and is editable at the same time, with large problems, such as visualizations provide too high a level of aggregation and cannot display the detail necessary for interaction. We explain ...

The deployment of large-scale information systems is a major trend in the corporate world today due to a number of driving forces such as the Internet, globalization, and the use of IT for distributed knowledge. However, the adaptation process of such new technologies is not yet well understood. With its theoretical basis on structuration theory and actor network theory (ANT), this study employ...

The paper deals with the problem of defining the territories for I68 sales agents of a German manufacturer of consumer goods. About 1400 postal areas constitute the basic geographical units. The problem is solved by means of a location-allocation approach involving a standard code of a primal network algorithm as well as a new heuristic for resolving split areas. Numerical results and the imple...

Twitch is a live video streaming platform used for broadcasting video gameplay, ranging from amateur players to eSports tournaments. This platform has gathered a substantial world wide community, reaching more than 1.7 million broadcasters and 100 million visitors every month. Twitch is fundamentally different from “static” content distribution platforms such as YouTube and Netflix, as streams ...

Making case adaptation practical is a longstanding challenge for casebased reasoning. One of the impediments to widespread use of automated case adaptation is the adaptation knowledge bottleneck: the adaptation process may require extensive domain knowledge, which may be difficult or expensive for system developers to provide. This paper advances a new approach to addressing this problem, propo...
