Efficient Computation Of Iceberg Cubes By Bounding Aggregate Functions, Xiuzhen Zhang, Pauline Lienhua Chou, Guozhu Dong

Kno.e.sis Publications

The iceberg cubing problem is to compute the multidimensional group-by partitions that satisfy given aggregation constraints. Pruning unproductive computation for iceberg cubing when nonantimonotone constraints are present is a great challenge because the aggregate functions do not increase or decrease monotonically along the subset relationship between partitions. In this paper, we propose a novel bound prune cubing (BP-Cubing) approach for iceberg cubing with nonantimonotone aggregation constraints. Given a cube over n dimensions, an aggregate for any group-by partition can be computed from aggregates for the most specific n--dimensional partitions (MSPs). The largest and smallest aggregate values computed this way become …

Semantics To Energize The Full Services Spectrum: Ontological Approach To Better Exploit Services At Technical And Business Levels, Amit P. Sheth

Kno.e.sis Publications

Services are pervasive in today’s economic landscape, and services- based architectures are being rapidly adopted as IT infrastructure. The need to take a broader perspective of services to include people and organizational descriptions as opposed to technical interface descriptions has already been recognized as part of an overall vision of services science [46, 100]. This article describes the Semantic Services Science (3S) model, which seeks to demonstrate the essential benefits of semantics in view of the broader vision of services science by using service descriptions that capture technical, human, organizational, and business value aspects. We assert that ontology-based semantic modeling …

Stochastic Modeling Of Retail Mortgage Loans Based On Past Due, Prepaid, And Default States, Chang Liu

Doctoral Dissertations

Stochastic models were developed that provide important measures related to retail mortgages and credit cards for the management of a bank. Based on Markov theory, two models were developed that predict mortgage portfolio size and expected duration of stay in each of the states, which are defined according to the criteria of Basel Accord II and the Federal Reserve Bank. Also, to facilitate comparisons among different types of credit products and different time periods, a model was developed to generate a health index for a retail mortgage. This model could be easily extended, using multivariate regression or multivariate time series …

Oil. China And Oil In The Asian Pacific Region: Rising Demand For Oil, Pablo Bustelo

New England Journal of Public Policy

China’s growing demand for oil is significantly changing the international geopolitics of energy, especially in the Asian Pacific region. The recent growth in oil consumption, combined with forecasts of increased oil imports (especially from the Middle East), have led to deep concern among Chinese leaders regarding their country’s energy security. They are responding in a number of different ways. In particular, they are searching for new sources of supply and seeking to control purchases and transport lanes, while boosting national production at any cost. This is already causing tension with the United States and other big oil consumers, such as …

Oil. Seeking Peace In The Niger Delta: Oil, Natural Gas, And Other Vital Resources, Darren Kew, David L. Phillips

New England Journal of Public Policy

Nigeria’s oil-rich Niger Delta region has seen little benefit from the billions of dollars earned from oil over the last four decades, prompting a growing but disorganized insurgency across the region. Irresponsible oil companies and government officials have reduced the Niger Delta to one of the most polluted environments on earth. Corrupt local and national politicians, many of whom came to power through rigged elections, have colluded to manipulate ethnic divisions amid poverty to loot the region’s wealth. Consequently, the people of the Niger Delta have no formal political voice in Nigeria’s nascent democratic system, increasing the appeal of militias …

Quo Vadis, Cs? – On The (Non)-Impact Of Conceptual Structures On The Semantic Web, Sebastian Rudolph, Markus Krotzsch, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Conceptual Structures is a field of research which shares abstract concepts and interests with recent work on knowledge representation for the Semantic Web. However, while the latter is an area of research and development which is rapidly expanding in recent years, the former fails to participate in these developments on a large scale. In this paper, we attempt to stimulate the Conceptual Structures community to catch the Semantic Web train.

A Semantic Framework For Identifying Events In A Service Oriented Architecture, Karthik Gomadam, Ajith Harshana Ranabahu, Lakshmish Ramaswamy, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

We propose a semantic framework for automatically identifying events as a step towards developing an adaptive middleware for Service Oriented Architecture (SOA). Current related research focuses on adapting to events that violate certain non-functional objectives of the service requestor. Given the large of number of events that can happen during the execution of a service, identifying events that can impact the non-functional objectives of a service request is a key challenge. To address this problem we propose an approach that allows service requestors to create semantically rich service requirement descriptions, called semantic templates. We propose a formal model for expressing …

Water. The Geopolitics Of Water, Paul Michael Wihbey, Ilan Berman

New England Journal of Public Policy

In the great geo-strategic game known as the Middle East, peace politics get much of the press and the attention of policy leaders. On occasion, oil takes center stage but often for the wrong reason (see, e.g., "The End of the Oil Era and the Price of Oil"). What is important to understand is that water is in fact the key strategic resource in the region and if you follow the flow of water, you'll follow the politics and policy machinations that lie at the heart of the Israeli-Syrian dialogue. IASPS Fellow in Strategy Paul Michael Wihbey co-authored an analysis …

A Dynamic-Trend Exponential Smoothing Model, Don Miller, Dan Williams

Publications and Research

Forecasters often encounter situations in which the local pattern of a time series is not expected to persist over the forecasting horizon. Since exponential smoothing models emphasize recent behavior, their forecasts may not be appropriate over longer horizons. In this paper, we develop a new model in which the local trend line projected by exponential smoothing converges asymptotically to an assumed future long-run trend line, which might be an extension of a historical long-run trend line. The rapidity of convergence is governed by a parameter. A familiar example is an economic series exhibiting persistent long-run trend with cyclic variation. This …

Oil. The Geopolitics Of Oil And Natural Gas, Alan Larson

New England Journal of Public Policy

Ensuring the reliability of global energy supplies will call for policies that both encourage the use of newer, cleaner energy technologies and address the political challenges posed by the world’s growing demand for oil and natural gas. U.S. policy seeks to encourage expansion and diversification of world energy supplies and to promote the transparency and democratic institutions that help energy-producing countries make the most productive use of their resources.

Oil. Geopolitics Reborn: Oil, Natural Gas, And Other Vital Resources, Michael T. Klare

New England Journal of Public Policy

Competition over vital resources is a potent source of international friction among nations and within states. The result is the increasing interplay of international and internal struggles and the growing militarization of the global energy resource quest.

Oil. Changing Geopolitics Of Oil In Asia & The Usa, Jay Hein, John Clark, Robert Ebel, Dong Hyung Cha, Richard Lotspeich

New England Journal of Public Policy

One of the most important responsibilities the United States assumed following World War II was ensuring the stable flow of relatively inexpensive oil to the industrialized and industrializing countries of the world. A glance at a list of the top petroleum exporting countries shows that most of them are poor, have despotic governments, and experience frequent bouts of political instability and ideological extremism.

Is Interpersonal Trust A Necessary Condition For Organisational Learning?, Siu Loon Hoe

Research Collection School Of Computing and Information Systems

The organisational behaviour and management literature has devoted a lot attention on various factors affecting organisational learning. While there has been much work done to examine trust in promoting organisational learning, there is a lack of consensus on the specific type of trust involved. The purpose of this paper is to highlight the importance of interpersonal trust in promoting organisational learning and propose a research agenda to test the extent of interpersonal trust on organisational learning. This paper contributes to the existing organisational learning literature by specifying a specific form of trust, interpersonal trust, which promotes organisational learning and proposing …

Relationship Web: Realizing The Memex Vision With The Help Of Semantic Web, Amit P. Sheth

Kno.e.sis Publications

Relationship Web takes us from "which document" could have information I need to "what's in the resources" that gives me the insight and knowledge I need for decision making. Dr. Vannevar Bush outlined his vision for Memex in a 1945 Atlantic Monthly article [1]. Describing how the human brain navigates an information space in what he called trailblazing, Dr. Bush said, "It operates by association. With one item in its grasp, it snaps instantly to the next that is suggested by the association of thoughts, in accordance with some intricate web of trails carried by the cells of the brain." …
