There are three aspects within this model. Firs, take the word meanings as a whole concept units, it has been once described as ‘pre-packaged experience’. In the second, these units can be further decomposed into component or features. Of the third, on behalf of the prototype theory, the word meanings or features can be decomposed into several fuzzy aggregates which are made up of category attributes. Leech claimed that in this way, the semantic component analysis also applies to semantic ambiguity study. I think that when study the fuzzy semantic category in the use of prototype theory, using this model not only can avoid mistakes which Shi An shi pointed out, but also can choose an appropriate semantic level which offer more convenient. In addition, if we do not make a clear distinction between family similarities and category members’ common attributes, but enlarge the use of family similarities on a broad significance, it is also able to overcome the prototype theory’s neglected areas of abstract semantic category.
This improved semantic analysis of prototype model is built on the compromise model, only in this way can it avoid an extreme analysis and categorization.
4. Relations among the Prototype Members、Prototype Theory and the Basic Level Category
In our daily life, most concept systems take the basic level category and the prototype member as their foundation. A category is possibly established in a basic plane while the prototype member is extremely a basic level category. The three are interdependent and intergrowth in man's understanding mechanism. Both of the basic category and the prototype theory are the charted psychological characterization and the product of human intellect.
4. 1 Close connections between Prototype Theory and Basic Level Category
What are the similarities and differences between the prototype theory and the basic level category? Professor Ungerer and Schmid pointed out that they are symbiotic relationship, based on the following two interdependent principles: The basic level category has advanced the greatest interrelated and absorbable information about the object and organism in the world, that is to say the basic level category has provided the greatest collection of relevant attributes which can be gathered in the most complete form in prototype and named by the name of the category[10]. For example, birds.
What the prototype theory and the basic level category have in common is: dominance, similarity, regionality. The basic level category with a prototype member just like a tool we use to categorize the concrete object and the organism in the world around us. And the prototype theory is the very theoretic reference which can fully apply to the practice after analyze and summarizes the outside world.
A prototype of the basic areas like level of the world around us to specific objects and areas of the organic tools, and prototype Category Theory is in virtue of this powerful tool in the analysis of the outside world, after concluding that the full application based on a theory of practice.
4. 2 Close connections between Prototype Members and Basic Level Category
The shape of basic level category overlaps so great that allows reliable Gestalt perception which make it easier to identify the prototype instance.
4. 2. 1 Maximizing function of the Prototype
The main use of the basic level category by prototype member is in the following two aspects:
1. The Prototype member maximizes the use of the basic levels category on its clarity. For the prototype member not only absorb the greatest attributes within the category, but also absorb the other greatest attributes which do not enjoyed to the other categories.
2. The prototype member maximizes the use of the gestalt perception for it integrates all the features of the important part.
4. 2. 2 Similarities between the Prototype and Basic Level Category
There are many similarities between prototype members and the basic level category.
1. Members in a basic level category have similar perception on the overall appearance as well as the greatest similarity of internal and can reflect a single mental imagery of a whole formation. The prototype member the largest similarities of the category, so as to take the prototype member as the cognition reference point and the similarity as the foundation, those who wanted to enter this category have to more or less get common or similar with the prototype member. There are a loose and unequal subjection family resemblance between the prototype member and the edge members.
2. Due to the different region and cultural environment of different people living, there are also some differences when divide in the basic level category or determine the prototype member For example, the Panda is unique in our country, and the koalas is a symbol of Australia. These are favorite of local people, for the life of the residents in these countries, these should be their basic category and the prototype samples, but it may not be accepted by other countries, may also be in other countries do not have.
