Attribute exploration is a formal concept analytical tool for knowledge discovery by interactive determination of the implications holding between a given set of attributes. The corresponding algorithm queries the user in an efficient way about the implications between the attributes. The result of the exploration process is a representative set of examples for the entire theory and a set of im...

A new stated preference technique is developed and tested. In an interactive computerized survey, respondents move continuous sliders to choose levels of environmental attributes. The total cost of the combination of attributes chosen is calculated according to a preprogrammed cost function, and continuously updated and displayed. Each registered choice reveals the respondent’s marginal willing...

The paper considers a discrete stochastic multicriteria problem. This problem can be defined by a finite set of actions A, a set of attributes X and a set of evaluations E. It is assumed that the performance probability distributions for each action on each attribute are known. A new procedure for such a problem is proposed. It is based on two concepts: stochastic dominance and interactive appr...

Meshes used in real-time applications are usually composed of sub-meshes which contain vertices with different sets of attributes. This kind of mesh cannot be used directly in the current graphics pipeline architecture because meshes for interactive applications usually duplicate vertices to ensure that every vertex has a single set of attributes. This fact causes apparently contiguous surfaces...

The selection of seismic attributes is a key process in reservoir prediction because the prediction accuracy relies on the reliability and credibility of the seismic attributes. However, effective selection method for useful seismic attributes is still a challenge. This paper presents a novel selection method of seismic attributes for reservoir prediction based on the gray relational degree (GR...

In this paper one of the fundamental problems of Shipbuilding Industry known as block assignment problem is modeled and solved. The irregular shape of blocks and the inherent intractability of this problem is the primary motivation to use the interactive genetic algorithms with a specialized chromosome level “repair” operator. Without loss of generality, some domain knowledge has been incorpora...

There currently are several views on human computer interaction in measuring interactive qualities of usability attributes: (1) the interaction-oriented view, (2) the user-oriented view, (3) the product-oriented view and (4) the formal view. Two different possibilities of measurement within the product-oriented view are introduced in this paper. Different types of user interfaces can be describ...

This paper presents a content-based interactive video browsing system to address the challenge in a live video search competition to find specific video clips from a large video collection under time constraints. Since the target of this evaluation forum is to evaluate and demonstrate the development of interactive video search tools, we do not need to consider if the most commonly used query-b...

We present a general method for employing interactive embedding techniques to enable an analyst to explore a larger collection of local patterns. The common idea among pattern-mining methods is to list descriptions of subsets of a dataset according to some interestingness measure. Because the space of all patterns in a dataset is exponentially large in the number of attributes, most pattern-min...

This paper proposes a way to overcome locking problems in interactive database applications by using awareness concepts. Parallel long running editing sessions in interactive database applications often cause locking conflicts. The occurrence of conflicts can be drastically decreased by giving users means to be aware of each other and to communicate. This paper explains how this is done in data...
