A computing theory for collaborative and transparent decision making under time constraint

In this paper, we present a computing theory on the accelerated critical point of selection of proper strategies between collaboration and competition and its mathematical analysis for collaborative and transparent decision making under “time constraint”, i.e., cost of time pressure, which decision makers face in negotiation. Web 2.0 provides a useful digital environment to support various time-stressed human behaviors for collaborative decision making. However, little research has examined the collaborative behavior under time constraint on the Internet in its designs and implementations on electronically supported decision making. Those systems are implemented in black boxes so that we need transparent designs of decision support systems to promote collaboration by time-stressed decision makers. The essential problem on collaborative decision making under time constraint is the discovery and evaluation on the critical point of selection of proper strategies between collaboration and competition. Most of the current decision support systems accept the half of maximum acceptable time for negotiation as a critical point, a priori, though that conventional point is often late for proper decision making. The proposed theory shows that a critical point is to be accelerated at the one-third of maximum acceptable time for negotiation. We have formulated the proposed computing theory based on mathematical formulation, and checked its feasibility in its applications to a case study. The proposed theory promotes collaborative and transparent decision making in consideration of the properties of stakes under time pressure by selecting the strategy of collaboration or competition at the much earlier stage.

Intellectual Property Protection for Multimedia Information Technology

Since previously published intellectual property law and business research discusses institutional analyses without interdisciplinary insights by technical experts, and technical references tend to concern engineering solutions without considering the social impact of institutional protection of multimedia digital information, there is a growing demand for a resource that bridges the gap between multimedia intellectual property protection law and technology. Intellectual Property Protection for Multimedia Information Technology provides scholars, management professionals, researchers, and lawyers in the field of multimedia information technology and its institutional practice with thorough coverage of the full range of issues surrounding multimedia intellectual property protection and its proper solutions from institutional, technical, and legal perspectives.

Decision making under time constraint: From heuristics to strategy

In this study, we discuss bilateral decision making under time constraint. The problem on time constraint is to evaluate the value of the cost of time for decision procedures. We propose a formula to compute the cost of time by introduction of opportunity cost to its evaluation. We also propose a formula on a strategic point for decision making under time constraint. The strategic point is located at the one-third of the entire or remaining duration for decision procedures instead of a heuristic point of its half time. We have conducted a feasibility check on the formulas on the cost of time and the strategic point in their applications to a case study.

Strategic decision making on group collaboration under temporary constraints

In this paper, we present an evaluation method for strategic decision making on group collaboration under temporary constraints for avoiding de-escalation moves. Group negotiation has two types of decision making: collaborative and competitive strategies. The collaborative strategy is a type of decision making under which any player in negotiation groups would not leave from non-rep eatable games of finite stakes on their possible agreements, while the competitive strategy is the other style of decision making under which any player in negotiation groups would leave for other repeatable games of infinite stakes on their possible agreements. Those two types of strategies are selective for increasing negotiated gains under temporary constraints in the response to properties of infinite and finite stakes on repeatable and non-rep eatable negotiation games, respectively. The proposed method provides decision support systems with the command of strategic decision making on group collaboration under temporary constraints.

Patenting the Processes for Content-Based Retrieval in Digital Libraries

In this paper, we report formulation and case study of the conditions for patenting processes of content-based retrieval in digital libraries, especially in image libraries. Inventors and practitioners demand formulation of the conditions for patenting the processes as computer-related programs in combining prior disclosed means, and also in comprising the means for parameter settings to perform certain functions. Content-based retrieval indexes the extracted features of images and classifies the indexes to perform its retrieval function. A process for content-based retrieval often consists of a combination of prior disclosed means. That process also comprises the means for parameter settings that are adjusted to retrieve a specific kind of image at a certain narrow domain. We formulate the conditions of patentability on processes for performing content-based retrieval in combining the prior disclosed means and/or comprising the means for parameter settings from the practical standpoints of technical advancement (nonobviousness) and specification (enablement).

A formulation for patenting content-based retrieval processes in digital libraries

In this paper, we present a formulation and case studies of the conditions for patenting content-based retrieval processes in digital libraries, especially in image libraries. Inventors and practitioners demand a formulation of the conditions for patenting data-processing processes as computer-related inventions in the form of computer programs. A process for content-based retrieval often consists of a combination of prior disclosed means and also comprises means for parameter setting that is adjusted to retrieve specific kinds of images in certain narrow domains. We focus on requirements for technical advancement (nonobviousness) in the combination of data-processing means, i.e., processes and specification (enablement) on the means for parameter setting in computer programs. Our formulation follows the standards of patent examination and litigation on computer-related inventions in the US. We confirm the feasibility and accountability of our formulation by applying it to several inventions patented in the US.

Copyrighting digital libraries from database designer perspective

In this paper, we discuss current issues on the copyright of digital libraries from a database designer perspective, and present a scheme for copyright protection of indexed digital contents stored in digital libraries that are associated with keyword-based retrieval operations.

A proposal for digital library protection

We propose systematic digital library protection by patentable content-based retrieval processes, especially on image digital libraries in specified domains, without any excessively exclusive protection in general domains.

A Study on Strategic Points for Decision Making Under Time Constraint

In this study, we discuss a theory on process for decision making under time constraint which is uncommon or asynchronous among two or bilateral decision makers. The problem on time constraint is to evaluate cost of time or value of the entire duration of a certain process for decision making. We propose a formula to compute cost of time by introduction of opportunity cost to its evaluation. We also propose a set of strategic points under asynchronous time constraint among bilateral decision makers. We have conducted a feasibility check on our proposed formulas on cost of time and the strategic points in their applications to a case study.
