System and method for retrieving building structure data and computer program therefor

Abstract

A system for retrieving building structure data. The system includes a building structure data base which stores building structure data and a retrieval unit for retrieving the data base. The building structure data includes a plurality of house plan data and a plurality of attribution information, each of which corresponds to each of the plurality of house plan data. The retrieval unit further includes an extraction unit for referring the plurality of attribution information to a house plan information entered externally, and extracting at least one house plan data which has an attribution information which is identical or similar to the house plan information.

What is claimed is:  
     
         1 . A system for retrieving building structure data, said system including: 
 a building structure data base storing a plurality of house plan data and a plurality of attribution information, each corresponding to each of said plurality of house plan data; and    a retrieval unit for retrieving said data base,    wherein said retrieval unit further includes: 
 an extraction unit for referring said plurality of attribution information to a desired house plan information entered externally, and extracting at least one house plan data which has an attribution information identical or similar to said desired house plan information.  
   
     
     
         2 . The system as claimed in  claim 1 , wherein said retrieval unit furthermore include a presenting unit functionally coupled to said extraction unit for receiving said extracted at least one house plan data and presenting said extracted at least one house plan data.  
     
     
         3 . The system as claimed in  claim 1 , wherein said plurality of attribution information include a positional information of each room and said desired house plan information includes said positional information of each room.  
     
     
         4 . The system as claimed in  claim 3 , wherein said positional information of each room is represented based on a direction with reference to a center of each floor.  
     
     
         5 . The system as claimed in  claim 3 , wherein said positional information of each room is represented based on one of partitions divided from an entirety of each floor.  
     
     
         6 . The system as claimed in  claim 3 , wherein said extraction unit extracts at least one house plan data which has an attribution information identical or similar to at least a part of said positional information of each room included in said desired house plan information.  
     
     
         7 . The system as claimed in  claim 1 , wherein said extraction unit extracts at least one house plan data which has an attribution information belonging to one of predetermined groups for said desired house plan information.  
     
     
         8 . The system as claimed in  claim 3 , wherein said extraction unit extracts at least one house plan data which has an attribution information identical to not only a room just designated based on said desired house plan information but also at least one adjacent room to said room just designated.  
     
     
         9 . The system as claimed in  claim 1 , wherein said extraction unit is functionally coupled through a network to at least a terminal which is operable by a user.  
     
     
         10 . The system as claimed in  claim 9 , wherein said extraction unit comprises a retrieval engine which provides a Web-page which enables said user to make an interactive entry procedure for entering said desired house plan information.  
     
     
         11 . The system as claimed in  claim 9 , wherein said building structure data base and said retrieval unit are placed over a network so that said building structure data base is uniformly maintained and managed through said network.  
     
     
         12 . A method of retrieving building structure data, said method including the steps of: 
 referring a plurality of attribution information, each of which corresponds to each of a plurality of house plan data which are included in building structure data stored in a building structure data base, to a desired house plan information entered externally; and    extracting at least one house plan data which has an attribution information which is identical or similar to said desired house plan information.    
     
     
         13 . The method as claimed in  claim 12 , further including the step of: 
 receiving said extracted at least one house plan data and presenting said extracted at least one house plan data.    
     
     
         14 . The method as claimed in  claim 12 , wherein said plurality of attribution information include a positional information of each room and said desired house plan information includes said positional information of each room.  
     
     
         15 . The method as claimed in  claim 14 , wherein said positional information of each room is represented based on a direction with reference to a center of each floor.  
     
     
         16 . The method as claimed in  claim 14 , wherein said positional information of each room is represented based on one of partitions divided from an entirety of each floor.  
     
     
         17 . The method as claimed in  claim 14 , wherein said extraction step extracts at least one house plan data which has an attribution information identical or similar to at least a part of said positional information of each room included in said desired house plan information.  
     
     
         18 . The method as claimed in  claim 12 , wherein said extraction step extracts at least one house plan data which has an attribution information belonging to one of predetermined groups for said desired house plan information.  
     
     
         19 . The method as claimed in  claim 14 , wherein said extraction step extracts at least one house plan data which has an attribution information identical to not only a room just designated based on said desired house plan information but also at least one adjacent room to said room just designated.
