Abstract
In a concept search, the user cannot easily create an effective seed document own his/her own. Further, the concept search trainer automatically changes the weights assigned to characteristic terms; however, such changes may not always increase the retrieval accuracy. The document retrieval method of the present invention uses thesaurus data to support the user's seed document creation in a first search cycle and presents newly extracted characteristic terms to the user in second and subsequent search cycles. The retrieval accuracy increases because the present invention provides a user interface that permits seed document adjustment.
Claims12
A computer-based document retrieval method, comprising the steps of:
- receiving a seed document entered by a user;
- memorizing first characteristic terms extracted from said seed document;
- memorizing second characteristic terms extracted from the result of a document search process performed on said seed document;
- and
- displaying the difference between said first characteristic terms and said second characteristic terms on screen.
A program for executing a method for electronic document retrieval, wherein said method comprises the steps of:
- receiving a seed document entered by a user;
- memorizing first characteristic terms extracted from said seed document;
- memorizing second characteristic terms extracted from the result of a document search process performed on said seed document;
- and
- displaying the difference between said first characteristic terms and said second characteristic terms on screen.
An electronic document retrieval system, comprising:
- means for receiving a seed document entered by a user;
- means for memorizing first characteristic terms extracted from said seed document and second characteristic terms extracted from the result of a document search process;
- and
- means for displaying the difference between said first characteristic terms and said second characteristic terms on screen.
A computer-based document retrieval method, comprising the steps of:
- memorizing first characteristic terms extracted from the result of a first search process;
- memorizing second characteristic terms extracted from the result of a second search process which is performed on the result of said first search process;
- comparing said first characteristic terms and said second characteristic terms;
- and
- displaying the result of said comparison on screen.
A computer-based document retrieval method, comprising the steps of:
- displaying characteristic terms extracted from the result of a document search process on screen;
- receiving a user's instruction for selecting said displayed characteristic terms;
- and
- memorizing the received instruction for selecting said characteristic terms.
A computer-based document retrieval method, comprising the steps of:
- causing thesaurus category information, which is stored in a storage device beforehand, to appear on screen;
- receiving a user's instruction for selecting said displayed thesaurus category information;
- and
- performing a document search process in accordance with the received instruction for selecting said thesaurus category information.
A computer-based document retrieval method, comprising the steps of:
- receiving first characteristic terms from a user;
- performing a search process on said first characteristic terms and displaying the result of said search process on screen;
- receiving second characteristic terms which are entered by the user in accordance with the result of said search process;
- comparing said first characteristic terms and said second characteristic terms;
- and
- displaying the result of said comparison on screen.
A computer-based document retrieval method, comprising the steps of:
- receiving first characteristic terms entered by a user;
- performing a first search process on said first characteristic terms and displaying the result of said first search process on screen;
- receiving second characteristic terms which are entered by the user in accordance with the displayed result of said first search process;
- comparing said first characteristic terms and said second characteristic terms;
- and
- performing a second search process in accordance with the result of said comparison.
A computer-readable storage medium storing a program for executing a computer-based document retrieval method, wherein said method comprises the steps of:
- receiving a seed document entered by a user;
- memorizing first characteristic terms extracted from said seed document;
- memorizing second characteristic terms extracted from the result of a document search process performed on said seed document;
- and
- displaying the difference between said first characteristic terms and said second characteristic terms on screen.
