Electronic Common Brain: ECBECB: Transformating the process of Human-Human to the process of Human-ECB(take on information relationship with group think)-Human in the process of group decision-making.

Argument Platform (Synchronization)With the group members idea produce and the exchangeobtain group members wisdomespecially the core decision-makers wisdom, to provide strategic&tactics methods and truss

It contains some modules,such as facilitator information distribution room,Brain-stroming argument room,facilitator-DPS concluding&summarizing room,Synthesis decision-making room


Argument Platform (Synchronization)


Argument Platform (Asynchronism)Providing the asynchronism argument platform with the mainly means of textall information then enter into the database after the transformation using ECBthe mainly purpose is to verify, express information with tree structure, and dis-cover the focus problems;It fit to the independe- ntly demonstrate individual

Module: decision task production argument room,decision task cognize AR,decision problem parse AR,decision problem solving AR, decision scheme design AR,ECBAR;


Argument Platform (Asynchronism)


Synthesis Decision-Making RoomFunction:select some or one solution from the set of standby solutions;

Now,It contains two support tools:1Solution voting tool: provide the way to vote for group memberseach can but select a solution;2DELPHI;

BackgroundArgument hall is a group support system, which is directed by the metasysthesis methodology, and with the purpose of solving complex problems(xusen,qian et.al.1990DeSanctis G R et.,al.1987)

Group communication with the computer-based environment, information has a large number, the members idea is various, the evidence source is board, usually exceed members ability to process information.

In the argument process, the subject and decision purpose usually ate out of focus, it is easy to cause knowledge fault and information overload (Jinle, Sun, Pengzhu, zhang2001);


BackgroundTraditional group argument, only by the way of individual memory, text record, sound record and so on, not depend on the tools of multi-media and web visualization,lots of information and their relation are lack of visual expression, group members are easy to submerge into the great number information

Meanwhile, argument process cant divert with the members purpose, individual has large limit about information grasp, understand, memory and apply, it is difficult to form group focus in the argument process;


BackgroundIn practice, time and the consensus are two important factor. Argument information visualization increase the effect of group communication, assist to avoid the diverge to problem, enrich the methods of research and cognize means to dig out information, and reduce the time to cognize the decision problems(J Larkin, H Simon, 1987); promote group to learn each other and obtain consensus; otherwise, it is a useful way to relax information overload


BackgroundVisualization provide a efficiency data structure, it gives a well support to overcome information overload, cognize burden, increase group output and innovation ability; visualization can assist to shorten group cognitive time of decision problems, promote members to learn each other to obtain consensus, then explode groups visualize thought, and give a effect information sharing mode and information statistic function;


The Theory Foundation Cognitive process, cognitive stimulation and interferenceTo test the affection of shared information and evaluated views on idea generation and mental processes of group members, it is necessary to discuss the mental processes. Nijstad, Stroebe and Lodewijkx (2002) developed a theory of idea generation called SIAM SIAM:it is a practice apply of SAM(search of associative memory model of memory retrieval) in the ideas produce(Raaijmakers and Shiffrin);

SIAM treat the ideas produce as a repeat search process of memory


SLAMIdeas cant produce without foundationit must depend on the known knowledgecf. Amabile,1983 SIAM:Short term memorySTM) and long term memoryLTM) STM:consciousness activitycapability is limited;LTMcapability is unlimited,knowledge storeageKnowledge divide into images or character combination with the strong link and semantic correlative;these images joint the associationslevels and categories into a abundant networkAssume that semantic correlative images have a strong link (Collins & Loftus, 1975)At one time, only one image can be enabled


The theory FoundationTwo basic graph:influence diagra-mming and cognitive mapping

The two methods all are the expression of the relationship of conceptionsConsist of many nodes and arc; node:Concepts; Arc:Semantic relationships;


Argument Network


Visualization LevelAccording to the different requirement of visualization,we classify the group decision-making visualization to three levels:nature visualization, self-determination visualization, intelligent visualization;

IntelligentSelf-determinationNature AutoCustomizeNatureGroup decision-makingH-C interactCognizeSynthseisRequirement Levels, increase


Nature Visualization

Contains single information visualization, the relation of information visualizationobtain nature argument tree4-1 ECBAR


Self-dertermination VisualizationSelf-determination visualization obtains argument tree with different exhibit methods that called self-determination argument tree in terms of group members requirement

Contains: different exhibit methods,such as subject ,speaker,node power,consensus status ,attention status time-based process visualization; speaker-based visualization, it contains:stand out the speaker and only show the speakers information others:different levels of argument tree;how many nodes to exhibit,an so on


Intelligent VisualizationDig the usefull information from the argument process and the information produced in the process;

On the view of convenient for synthesizing H-C, using visualization technology to give a effective tools for group argument;

In our mis center, we have designed and developed the intelligent visualization technology of consensus evaluation,analysis and forecast;


Consensus Evaluation&Forecast Visualization


Consensus Analysis Visualization


Experiment Results:1hold the argument process2argument interest and positivity of group members3understand other members ideas2get rid of information load strongly3argument sufficiency4more quick to gain consensus5the higher consensus level


What we are DoingInformation trackingInformation exhibit & intelligent visualization methods;The design and development of support platform for facilitatorGASS-based knowledge managementGASS apply in the finance-watch


Information TracingInformation overloadInformation summarizeSummarized informationOriginality informationInformation tracking


Information Expressing&Methods of Intelligent VisualizationNature visualizationprovide more plenty argument information;

Self-determination visualization:According to different roles information requirementargument membersexpertsfacilitatorDPSprovide customized exhibit methods

Intelligent visualizationmore visualization methods to assistant decision;
