Description

Implicit knowledge method for visualizing based on use-case
Technical field
The present invention relates to the Knowledge Visualization technical field.
Background technology
Human cognitive is very unique, it is very special when it processes language and non-language object at the same time, represent that with visual form and linguistic form information can strengthen memory and identification significantly simultaneously, its effect will be better than far away separately and represent with visual form or linguistic form.Implicit knowledge is highly personalized knowledge, and it is rooted in behavior itself dearly, is planted in the constraint of individual environment of living in.Implicit knowledge is a kind of form, be difficult to through long-term accumulation to use in practice language performance, propagation and shared personalized empirical knowledge of height.The characteristics of implicit knowledge are as follows:
(1) non-coding: different from the easy numeralization of Explicit Knowledge, implicit knowledge mainly exists with potential forms such as intuition, inspiration, experience, perception, technical knowhow, behavioural norm, sense of community, corporate culture, valuess, be difficult to formal representations such as language, literal, chart, symbols, be difficult to obtain by the mode of books study and instruction.
(2) path dependence: implicit knowledge is the empirical knowledge that constantly accumulates in practice, its accumulation must be take certain implicit knowledge storage as the basis, the increment implicit knowledge of enterprise strictly depends on the storage implicit knowledge of enterprise, Here it is path dependence that implicit knowledge shows.
(3) monopoly: at first, from the angle of tacit knowledge mainbody psychology, main body often in the early stage grope middle a large amount of energy and the cost of having dropped into, the process of obtaining implicit knowledge is more difficult; Secondly, the income that implicit knowledge brings is large than Explicit Knowledge, and this just forces tacit knowledge mainbody can initiatively not exchange and transfer the possession of easily oneself experience or technical knowhow with other people, thereby so that the interchange of implicit knowledge and transfer are more difficult.
(4) to the dependency of environment: certain implicit knowledge always produces in certain environment, and long-term existence and development under this environment, in case broken away from this specific environment, this kind implicit knowledge also can disappear thereupon.That is to say that implicit knowledge always depends on certain specific environment, the change of environment will make it lose the basis of Existence and development.
Knowledge Visualization is the emerging technology field that grows up on the basis of visualization in scientific computing, data visualization and information visualization.It refers to present with the vision characterization method a kind of mode of knowledge, and essence is that the individual knowledge with people shows with graphic means, and formation can directly act on the knowledge external expressive form of people's sense organ, thereby promotes transmission of knowledge and innovation.
The dual coding theory provides theoretical foundation for Knowledge Visualization, this theory is emphasized in storage, processing and the leaching process in information, the process of information processing of language and non-language is no less important, because " people's cognition is unique, and it is exclusively used in simultaneously the processing to things and the event of language and non-language; In addition, language system is special, and directly with oral and process in writing form input and the output of language, meanwhile, it is the in store mark function relevant with things, event and the behavior of non-words and phrases again for it.Any theory of representation all must be fit to this dual-use function " (Pavio, 1986).The dual coding theory hypothesis exists the subsystem of two cognitions, and one is exclusively used in sign and the processing to non-words and phrases things, event, and another then is used for the processing of language.Pavio is also supposition simultaneously, has two kinds of different characterization units: be applicable to " image cell " of psychological map and be applicable to " linguistic unit " of entity language.The former is according to the relation tissue of part and integral body, and the latter is according to association and hierarchical organization.The dual coding theory also identifies three kinds of processing types:
Sign property: directly activate signs words and phrases or non-words and phrases;
The property called: utilize non-words and phrases system to activate the words and phrases system;
Association property: activate in the inside of same words and phrases or non-words and phrases system and to characterize.
The theoretical most important principle of dual coding is exactly: can be by strengthen simultaneously memory and the identification of information with the form presentation information of vision and language.Therefore, the Knowledge Visualization technology shows the visualization means such as graph image of abstract knowledge with image, will greatly improve the identifiability of knowledge, makes knowledge be easier to memory, understand, process and use.As a kind of graphic mode to abstract knowledge, Knowledge Visualization has following features:
(1) visualize, structuring.From in form, it has image, characteristics intuitively on the one hand, as in the photography and vedio recording course, the knowledge point of mode of composition is presented with picture or one section image, so just makes the original abstract composition knowledge visual pattern that becomes, and also is more conducive to hold and use; Also present on the other hand structures, not only clear as to present concept or knowledge point, more can show the structural relation between them, be exactly like this such as the concept map instrument to the result of knowledge.
(2) degree of depth, this materialization.On content, it is that the degree of depth of the implicit speciality of knowledge is excavated.A research direction of Knowledge Visualization is automatically to excavate concept system implicit in the text message by computing machine, such as character in a novel and relation thereof, concept in the scientific popular article and relation thereof, automatically generate chart etc., for prepare lesson provides starting material and provides original framework for the student further processes.
(3) high efficiency, high quality.On effect, Knowledge Visualization is optimized knowledge, and can must be obtained by high-level efficiency.From pro forma directly perceived, vivid, structure is clearly demarcated, and the essence on the content, deep has all determined these characteristics.What Knowledge Visualization was pursued is: make sightless knowledge become the clear knowledge that presents.Visualize, structuring, this materialization by knowledge presenting, promote transmission of knowledge and innovation, not only transmit true, also transmit opinion, experience, attitude, values, expectation, viewpoint, suggestion and prediction etc., and help by this way other people correctly reconstruct, memory and these knowledge of application.
Present stage the Knowledge Visualization method:
(1) concept map: concept map is that Cécile Nowak (J.D.Novak) doctor of Cornell University is according to a kind of instrument that is used for organizing and characterizing knowledge of the theoretical proposition of meaningful learning of Su Beier difficult to understand (David P.Ausubel), be also referred to as concept mapping or concept map, the former pays attention to the detailed process that concept map is made, the latter pays attention to the end product that concept map is made, but now generally concept mapping and concept map is referred to as concept map and is not added on strict difference.It places the Conceptions of a certain theme among circle or the square frame usually, then with line relevant concept and proposition is coupled together, and indicates two meanings relations between the concept on the line." concept one conjunction one concept " such tlv triple has formed a proposition.In addition, concept map has hierarchical structure, and five-star concept is in the top.People can illustrate relation between the concept of different levels with the conjunctive word that is fit to, and determine the lateral ties between the different branches.Concept map is as a kind of strategy of the representation of knowledge, its great advantage is the architecture of knowledge very clear as to express, and outstanding behaviours architectonic hierarchical structure, can effectively change student's cognitive style, large tracts of land improves student's school grade, improves effectively teacher's teaching efficiency.
(2) mind map: mind map is a kind of notes method that Englishman's Tuo Ni Bazin sixties in 20th century (Tony Buzan) is created at first.Its initial purpose just for improve traditional draw up notes bury keyword, be difficult for memory, lose time and can not the effective stimulus brain etc. shortcoming, but its practical function and power are further than this.The specific practice of drawing mind map is: on a piece of paper all Information Organizations on a tree-shaped structural drawing, all write keyword or the short sentence of different concepts in each branch, each concept classification and be distributed on the figure with having levels, again abrim color and image on this figure, and this has simulated the mode that brain self is carried out the work just.According to full brain concept principle, doing like this to stimulate left brain and right brain simultaneously, transfer comprehensively the logic of left brain, sequentially, image, the imagination, color, space and the organism thinking of regulations, literal, numeral and right brain, make brain potential obtain the most sufficient exploitation, allow the people when thinking, memory, analysis, fully excavate potential, excite inspiration and the imagination.Mind map has been widely used in the various aspects of study, work, life since being born, it successfully helps the whole world 2.5 hundred million people to change life, is described as the global media of thinking of 21 century.
(3) cognitive map: cognitive map is also referred to as cause-and-effect diagram (Causal Maps), is proposed by Ackerman and Eden (2001), and it (ideas) as node, and is connected with each other " idea " with it.Idea is different from concept, and they are sentence or paragraph mostly.Cognitive map (Eden, 1988; 1992) propose as the basis take individual Theory Construction (Personal Construct Theory), wherein " idea " all is to link up by the connecting line with arrow, but there is not conjunction on the connecting line, the implicit meaning of connecting line is " cause-effect relationship " or " causing ", and does not have stratified restriction.Cognitive map is mainly used in helping people's planning, promotes the decision-making of group.
(4) semantic network: in psychology, semantic network is defined as Semantic Similarity or the degree of correlation of word or concept.Yet Fisher (1990) is defined as node and the network that connects to form with it, conjunction is arranged but strictly is not limited on the hierarchical structure.Semantic network is more as concept map like this, and in mainstream psychology and computer science, define.The same with concept map, semantic network forms basic example or proposition take concept and significant, not limited conjunction as the basis.Fisher (2000) think semantic network can be seen as multidimensional but not the two dimension.Semantic network can be very large, comprises hundreds and thousands of concepts that are mutually related.Because it is very large, the user at a time can only see one of them part, namely with the concept of central concept direct correlation.
Use-case is the description how descriptive system should ask to external world, is the technology that a kind of use scenes by the user obtains demand.A business objective or the task of how obtaining described in each set of uses case.The UML(illustration) for use-case has defined graphical symbol, still do not represent the full content of use-case with illustration, graphical symbol can only provide the simplified summary of use-case.Use-case comprises that also the contents such as summary, precondition, trigger, elementary event stream, alternative path, postcondition, business rule, explanation express with mode word.
The advantage of use-case is as follows:
Use-case is verified to be understood easilier by service-user, so it also is that developer and final user well link up bridge; Use-case for definite scope of great use, finished item becomes easily thereby use-case is so that pay stage by stage step by step, they can relatively be easy to interpolation or remove from software project when relative importance value changes; Use-case can be followed the tracks of; Use-case can be as estimation, the basis of formulation progress and checking achievement; Use-case has prevented jejune design; Use-case does not use language-specific; Use-case allows us to go to tell a story, and can be easy to adopt demand is converted to story or this concrete method of scene is described use-case; Use-case is reusable in project, and use-case can both further develop in the iteration each time, and use-case can be used for catching demand, becomes programmer's exploitation foundation, develops into test case, to becoming at last user manual; Use-case is relevant with user and system interaction, and they made the software developer before exploitation or centrally just can begin user interface design; Use-case places context with demand, and they can clearly describe the relation between business activity.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of implicit knowledge method for visualizing based on use-case, intuitive is strong, logicality is strong, it is tighter to express, can make things convenient for the user to understand the purposes of knowledge, strengthen the user for the memory of knowledge, improve work tightness and efficient.
