Abstract

A computerized document processing apparatus for creating an abstract includes document storage for storing a computerized document, keyword storage for storing keywords, an abstract creation section for creating an abstract by extracting at least a character string containing a keyword stored in the keyword storage section from the computerized document stored in the document storage section, a document modification section for modifying the computerized document to link the keyword in the computerized document with the same keyword in the abstract, and a display section for displaying the abstract and the modified document that is linked with the abstract. The modified document is displayed when the linked keyword in the abstract is selected.

Claims

1. A computerized document apparatus for creating an abstract, comprising:

an input port for receiving at least one keyword and at least one logical condition;

a keyword storage device configured to store the at least one keyword;

retrieving means for;

transmitting a retrieve request, including the keyword and said logical condition, to a plurality of servers; and

receiving a plurality of retrieve results from the plurality of servers, the results including a plurality of computerized documents which contain the keyword and satisfy the logical condition;

a document storage device configured to store said plurality of documents;

a merging module configured to generate a ranking of the plurality of retrieved documents; and

an abstract creation module for;

creating a plurality of abstracts, each corresponding to one of the plurality of documents included in the ranking, by extracting at least a character string containing the at least one keyword stored in the keyword storage device from each of the computerized documents stored in the document storage device and inserting tags for linking to a position of the keyword in the computerized documents in the extracted character string;

generating modified copies of the stored computerized documents by inserting, in said modified copies, tags for linking positions of the keyword in the abstracts with positions within the modified copies in which the keyword occurs, wherein the modified copies of the stored computerized documents are stored in the document storage device;

combining the plurality of abstracts into a single abstract document; and

displaying the single abstract document and the positions in the modified copies of the computerized documents that are linked with keywords in the single abstract document, whereby the positions in the modified copies are retrieved from the document storage device and displayed when the linked keywords in the abstract are chosen.

2. The apparatus of claim 1, wherein the merging module generates the ranking of the plurality of retrieved documents by determining a number of the retrieve results which include each of said documents.

3. The apparatus of claim 1, wherein the merging module generates the ranking of the plurality of retrieved documents by averaging rankings associated with the documents included in the retrieve results from the plurality of servers.

4. The apparatus of claim 1, wherein the merging module generates the ranking of the plurality of retrieved documents by ranking the documents according to at least one of a creation date and a registration date.
