SEMANTIC ANALYSIS: RESEARCH TECHNIQUE

Data Processing

 

Data processing and analysis is performed on the "Basic Module" and it falls into two stages: preliminary and mathematical.

 

1. Preliminary Processing

 

On this stage a researcher has an opportunity to prepare "data sets" that represent the calculated semantic coordinates (see below), proceeding from the tasks relevant to researcher.

 

Conditions for set formation:

 

  • Data filtration allows the researcher to classify expert-submitted data in terms of a definite age group, gender, category, and calendar date of data input.

  • An option to restrict the subject content and scales out of the ones available in a project (with the purpose of the most flexible and detailed problem study).

  • Setting a number of analyzed subject states that characterize independent sense variants of subject perception within the studied mentalities.

  • Selection of bilateral significance level for the criterion for rejecting the data from marginal experts of the studied mentality.

 

Set preparation consists of the following stages:

 

  1. Creation of a data set starts with the calculation of a subject's semantic coordinates for every separate expert.

  2. Rejection of semantic descriptions and subject priorities that do not comply with the specified significance level (rejection of marginal experts who gave estimates discordant with those of the group).

  3. Calculation of semantic coordinates, rigidities of the selected number of states as well as probabilities of realizing these states for each subject after all the first-stage data has been collected.

  4. Entering the result set into the database for further use in mathematical analysis with set parameters indicated (conditions of noise filtration, expert categories, scales, subject list, etc.)

 

A researcher has an option to create an arbitrary number of sets, which gives him the opportunity to concentrate on the information (mathematical) data analysis, without returning to the initial data every time. The proposed data storage structure makes it possible to save initial data intact, which opens the way for its extension due to the experts actually participating in the project or potentially involved.

 

2. Mathematical Analysis

 

Using this mode, a researcher can calculate the following characteristics and parameters of the selected mentality:

 

  • Relative and absolute semantic coordinates of the states (subjects) and their probabilities.

  • Rigidity of properties and states.

  • Factor weights of the properties/characteristics (factor significance) and factor semantic representation of subject states (factor weights of research subjects).

  • After "varimax"-rotation of the factors one can get categorial weights of the properties and categorial semantic representation of subject states.

  • Semantic representation of a motive in factor and categorial representation.

  • Weight of states in research subject priorities.

  • Weights of factors and categories  (factor and category contribution) in research subject priorities.

  • Degree of subject's proximity to the motivational vector.
