This paper describes the concept and development briefly of the linquistic information aggregation operator,according to the different attribute weight,divides the linguistic information assessment under the uncertain condition into different kinds,and makes systematic analysis on the system,and probes deeply into the trend of the research on the linguistic information assessment.

On select approach to multi-plan based on linguistic assessment information;

Then an integrated multi-index method based on the linguistic assessment information is used.

In this method,linguistic assessment information is transformed into triangula.

An Approach to Group Decision Making Based on 2-dimension Linguistic Assessment Information

For group multi-criteria clustering problems with linguistic assessment information,a new method is proposed,in which the decision-makers weights are incomplete certain,and so are criteria weights.

As concerning group multi-criteria assignment problem with linguistic assessment information,a new method is proposed,in which the decision-makers weights are uncertain,and so are criteria weights.

Tentative views on means of discourse and language information;

Different approaches of semantics have their own focus in their inquiry of semantic principles and their achievements brought by the adoption of their unique methods reveal various features of language information.

The research of information related to language includes three parts: the language information encoding in communication technology,language information processing and the information structure of language.

Firstly the transformation between linguistic information and intuitionistic fuzzy value is determined.

The known evaluation scales of linguistic information are analyzed,and their disadvantages are pointed out.

Aim The group decision-making problems are studied in which all attribute weights and attribute values take the form of linguistic information.
