Method, device and system for processing, browsing and searching an electronic documents

A computer-implemented system for improving searchability of an electronic document, the system comprising:

• a computer,
• wherein the computer is configured to:
• analyze contents of electronic documents, while authors are composing electronic documents;
• create one or more queries corresponding to contents of electronic documents, while authors are composing the electronic documents, in order to create the queries, the computer is further configured to:
• calculate relevance degree of a term vector of a previous text segment and a term vector of a current text segment, the term vector of the previous text segment including a weight of each word included in the previous text segment, the term vector of the current text segment including a weight of each word included in the current text segment;
• if the relevance degree is higher than a threshold,
• decrease the term vector of the previous text segment by values of multiplications of every weight of the each word of the previous text segment and an attenuation factor;
• merge the term vector of the previous text segment and the term vector of the current text segment;
• replace the term vector of the previous text segment with the merged term vector;
• merge the previous text segment with the current text segment;
• and
• replace the current text segment with the merged text segment;
• if the relevance degree is less than or equal to the threshold,
• replace the term vector of the previous text segment with the term vector of the current text segment;
• and
• replace the current text segment with the previous text segment;
• store the one or more created queries with the electronic documents;
• receive a second query from a user;
• search the created one or more queries, which are same or related to the second query;
• present the user with one or more searched queries which are same or related to the second query;
• enable the user to select one or more of the presented queries;
• and
• present content of an electronic document corresponding the selected one or more queries.

An electronic document retrieving method, the method comprising steps of:

• extracting, by a computer, one or more queries stored with electronic documents, wherein each of the one or more extracted queries including one or more of:
• keywords, keyword string and questions, related to contents of the electronic documents, the extracting the queries including:
• calculating relevance degree of a term vector of a previous text segment and a term vector of a current text segment, the term vector of the previous text segment including a weight of each word included in the previous text segment, the term vector of the current text segment including a weight of each word included in the current text segment;
• if the relevance degree is higher than a threshold,
• decreasing the term vector of the previous text segment by values of multiplications of every weight of the each word of the previous text segment and an attenuation factor;
• merging the term vector of the previous text segment and the term vector of the current text segment;
• replacing the term vector of the previous text segment with the merged term vector;
• merging the previous text segment with the current text segment;
• and
• replacing the current text segment with the merged text segment;
• if the relevance degree is less than or equal to the threshold,
• replacing the term vector of the previous text segment with the term vector of the current text segment;
• and
• replacing the current text segment with the previous text segment;
• generating indices for the extracted one or more queries;
• receiving, at the computer, a second query from a user;
• in response to receiving the second query, searching, by the computer, the one or more extracted queries, which are same or related to the second query;
• presenting the user with said same or related queries;
• enabling the user to select one or more of said same or related queries;
• and
• providing the user with an electronic document corresponding to the selected one or more queries.

• and
• replace the current text segment with the previous text segment;
• generate indices for the one or more extracted queries, and store the generated indices;
• receive a second query from a user;
• search the one or more extracted queries, which are same with or related to the second query;
• present the user with the same or related queries;
• enable the user to select one or more of the same or related queries;
• and
• provide the user with an electronic document corresponding to the selected one or more queries.
