NiagaraCQ: A Scalable Continuous Query System for Internet Databases
- In SIGMOD
, 2000
"... Continuous queries are persistent queries that allow users to receive new results when they become available. While continuous query systems can transform a passive web into an active environment, they need to be able to support millions of queries due to the scale of the Internet. No existing syste ..."

systems have achieved this level of scalability. NiagaraCQ addresses this problem by grouping continuous queries based on the observation that many web queries share similar structures. Grouped queries can share the common computation, tend to fit in memory and can reduce the I/O cost significantly
Web-based Multi-Criteria Group Decision Support
"... Abstract — Organizational decisions are often made in groups where group members may be distributed geographically in different locations. Furthermore, a decision-making process, in practice, frequently involves various uncertain factors including linguistic expressions of decision makers ’ preferen ..."

that is in a most acceptable degree of the group. Moreover, this study implements the method by developing a web-based group decision support system. This system allows decision makers to participate a group decision-making through the web, and manages the group decision-making process as a whole, from
Web-Based Collaborative Multi-Criteria Decision Making
"... This paper describes a web-based environment for collaborative (group) multicriteria decision making and semantical analysis. The environment is built on top of a web-meeting tool that facilitates both synchronous and asynchronous discussions, data collection, and results analysis. While there ar ..."

there are a number of tools available that support web-based collaboration and decision making the results analysis in this system is unique. The back-end for the decision making environment is a multicriteria decision engine based on fuzzy set and fuzzy integration theories.
A Web-Based High-Performance Multicriteria Decision Support System for Medical Diagnosis
"... Multicriteria decision making ~MCDM! methods can be powerful aids for evaluating patients’ medical information in medical diagnostic systems. Technique ordered preference by similarity to the ideal solution ~TOPSIS! is one of the more widely used MCDM methods in decision support systems. For the pur ..."

. For the purpose of this work, the TOPSIS method is modified into a more suitable form and used for the implementation of a web-based medical diagnostic system. In our modified TOPSIS method, we have utilized fuzzy logic so that users can more accurately describe their symptoms. The data given to the modified
A Web-based Decision Support System with ELECTRE III for a Personalised Ranking of British Universities
"... Abstract: Reliance upon multi-criteria decision methods, like ELECTRE III, has increased many folds in the past few years. However, ELECTRE III has not yet been applied in ranking universities. League tables are important because they may have an impact on the number and quality of the students. The ..."

. The tables serve an indication of prestige. This paper describes a three-tier Web-system, which produces a customised ranking of British Universities with ELECTRE III reflecting personal preferences, where information is uncertain and vague. Using this case study, the benefits of ELECTRE III in the ranking

Constructing Linguistic Versions for the Multicriteria Decision Support Systems Preference Ranking Organization Method for Enrichment Evaluation I and II
"... The environmental impact assessment (EIA) is a real problem of multicriteria decision making (MCDM) where information, as much quantitative as qualitative, coexists. The traditional methods of MCDM developed for the EIA discriminates in favor of quantitative information at the expense of qualitative ..."

, with information of any nature. Therefore, the application of this method to real problems will lead to better results in MCDM. The main interest of our investigation group currently is to develop a set of different multicriteria decision fuzzy methods to be integrated inside a software program that works as a
An Asynchronous Group Decision Support System Study for Intelligent Multicriteria Decision Making
- Hawaii Conference on System Sciences, IEEE
, 1999
"... In modern business world group decision-making is becoming an extremely important activity. Recent research on computerized group decision support has focused extensively on supporting people co-located in place and time. There is a need, however, for more research focused on asynchronous group deci ..."

decision support systems (GDSS). Multicriteria decision-making (MCDM) theory has produced a wide range of techniques suitable for use in a variety of decision situations. With the support of an asynchronous GDSS which intelligently guides decision makers using an appropriate MCDM technique for a given task
Multi-Agents Model for Web-based Collaborative Decision Support Systems
