Building and space basically are the aggregate of the substance of three dimensions. In text description of buildings, architects freely uses line which is concept of one dimension and explain concept and composition of building which is three dimensions. Since the process on which we create meanings of words is based on our own mental activity, one word would have numerous meanings, which leads to polysemy. Equally, architects have described various meanings of words in terms of their linguistic activity. Meanings of line are organized by their own several recognitions to line. For these backgrounds, to consider the polysemy of line is important for evaluating the buildings created by architects. In this research we clarify polysemy of line in text description by architects.
The flow of this research is as below:
1. Extract the sentences that contain words associated with the meaning of line used by architects to explain their design of architecture in the architectural magazine, Shinkenchiku during 1950－2010.
2. Extract Type of Line, Adjectival Term, and Verbal Term. Type of Line is the word described as the line or related to it. Adjectival Term is the modifier for Type of Line to express its property and a state . Verbal Term is the modifier for Type of Line to express its action.
3. Analyze and consider the relationships between Type of Line and Adjectival Term, Type of Line and Verbal Term. After that, derive the tendencies of their relationships.
4. Categorize the relationships by creating a matrix in which the horizon axis is the tendency of Type of Line and Adjectival Term, and the vertical axis is of Type of Line and Verbal Term then derive aspects of polysemy of line.
As a result, four tendencies of the relationships between Type of Line and Adjectival Term were found: Line which shows system, Transfiguration of the line by a factor, Impresed line which occurs with the phenomena, Direction which occurs by visual recognition. And three tendencies of the relationships between Type of Line and Verbal Term were found: Manifestation of the line with recognition, Technical skill which completes system, Delivery and reception of the line which exists in the space.
Through the investigation of a matrix, 25 different types of interpretations about polysemy of line were derived. Within these types, four major frameworks were found as below: Line which records the consecutive movement, Line which shows the recognizable present phenomena, Line which sumilates appearable phenomena, Line where concept of time exists with the experience, interpretation, recognition and sensitivity of the human multidimensionally. Architects have regarded these four lines in 4 phases, conception, planning design, completed building and utilization of architecture and have utilized the right line for the right place. At that time, it revealed that architects do not only provide a certain concept by line, but also influence completely other phenomena, influence it by mixing other phenomena and create the egotistical and ideal situation.
Since time and a human being are mixed in the architecture and space that are physically three dimensions, various dimensions coexist, and the architecture and space cannot be called merely three dimensions. Also, the description about the line was able to confirm the expression to make a round trip to the dimension. Therefore, among space, time and human, it revealed that the architects regarded a building flexibly through a line by making a round trip to the various dimensions.
