Abstract
A system and method retrieving a XML document includes a DTD (Document Type Definition) reduction module for making a configuration file for index to be used in indexing and retrieving a document in which a complicated DTD is compressed, an index module for index the configuration file and the XML document inputted from the DTD reduction module, an index information storage module for storing the index information inputted from the index module and a retrieval module for retrieving a general query and a structure query inputted by an user.
Claims13
A system retrieving a XML document, comprising:
- a DTD (Document Type Definition) reduction means for making a configuration file for index to be used in indexing and retrieving a document wherein a complicated DTD is compressed;
- an index means for indexing the configuration file and the XML document inputted from the DTD reduction means;
- an index information storage means for storing the index information inputted from the index means;
- and
- a retrieval means for retrieving a general query and a structured query inputted by an user.
A retrieval method applied in the XML document retrieval system, comprising the steps of:
- a) converting a general query and a structure query inputted from an user into a query type corresponding to a retrieval engine;
- b) implementing similarity calculation between queries and document group by accessing the index information using the converted query;
- c) adjusting ranking of the document using the calculated similarity;
- and
- d) presenting some elements or the full document that are ranked.
In the XML document retrieval system equipped with a mass-storage processor, a computer-readable record media storing instruction for performing the functions of:
- converting a general query and a structure query inputted from a user into a query type corresponding to a retrieval engine;
- implementing similarity calculation between queries and document group by accessing the index information using the converted query;
- adjusting a rank of the document using the calculated similarity;
- and
- presenting some elements or the full document that are ranked.
