Traditional data envelopment analysis (DEA) models evaluate two-stage decision making unit (DMU) as a black box and neglect the connectivity may exist among the stages. This paper looks inside the system by considering the intermediate activities between the stages where the first stage uses inputs to produce outputs which are the inputs to the second stage along with its own inputs. Additional...

TheWeb of Data keeps growing rapidly. However, the full exploitation of this large amount of structured data faces numerous challenges like usability, scalability, imprecise information needs and data change. We present Semplore, an IR-based system that aims at addressing these issues. Semplore supports intuitive faceted search and complexqueries both on text and structureddata. It combines imp...

We use the martingale-theoretic approach of game-theoretic probability to incorporate imprecision into study randomness. In particular, we define several notions randomness associated with interval, rather than precise, forecasting systems, and their properties. The richer mathematical structure that thus arises lets us, amongst other things, better understand place existing results for precise...

Imprecise inference models the ability to infer sets of values or information chunks. Imprecise database inference is just as important as precise inference. In fact, it is more prevalent than its precise counterpart even in precise databases. Analyzing the extent of imprecise inference is important in knowledge discovery and database security. Imprecise inference analysis can be used to \mine"...

The CP conference is the annual international conference on constraint programming. It is concerned with all aspects of computing with constraints, including theory, algorithms, environments, languages, models, systems, and applications such as decision-making, resource allocation, scheduling, configuration, and planning. The CP community is very keen to ensure it remains open to interdisciplin...

Many problems in computational sustainability involve constraints on connectivity. When designing a new wildlife corridor, we need it to be geographically connected. When planning the harvest of a forest, we need new areas to harvest to be connected to areas that have already been harvested so we can access them easily. And when town planning, we need to connect new homes to the existing utilit...

Managing Large-scale Probabilistic Databases Christopher Ré Chair of the Supervisory Committee: Professor Dan Suciu Computer Science & Engineering Modern applications are driven by data, and increasingly the data driving these applications are imprecise. The set of applications that generate imprecise data is diverse: In sensor database applications, the goal is to measure some aspect of the ph...

sustainability concept in agriculture is becoming widespread throughout industries in many fields even in crop production, livestock production and etc. sustainable in agriculture is believed can give present and future good benefit to the farmers and society. however, in dairy sector in malaysia, the sustainability concepts and practices seems not fully aware by the farmers which result in low...
