System and methods for citation database construction and for allowing quick understanding of scientific papers

A computer-implemented method for constructing a citation database, comprising:

• storing initial non-full text information about a citation paper in a citation database;
• receiving a first request from a first computer device operated by a first user for information about the citation paper in the citation database;
• sending non-full text information about the citation paper from the citation database to the first computer device;
• allowing the first user to search on the Internet for a link to a network location storing full-text content of the citation paper;
• receiving the link to the network location from the first computer device;
• and
• storing the link to the network location in the citation database in association with the non-full text information of the citation paper.

A computer-implemented method for constructing a citation database, comprising:

• storing a first set of information about a citation paper in a citation database;
• searching for a source paper that cites the citation paper;
• extracting, from the source paper, a remark about the citation paper;
• storing the remark about the citation paper in the citation database in association with the first set of information about the citation paper;
• receiving, from a computer device, a request for information about the citation paper;
• and
• sending, to the computer device, the remark about the citation paper by the source paper and the first set of information about the citation paper.

A computer-implemented method for constructing a citation database, comprising:

• storing a first set of information about a citation paper in a citation database;
• receiving a request from a computer device for information about the citation paper in the citation database;
• automatically searching on an external database for the citation paper by a computer processing system;
• identifying at east a portion of the first set of information associated with the citation paper in the external database;
• finding a second set of information about the citation paper stored in the external database;
• retrieving the second set of information about the citation paper from the external database;
• storing the second set of information about the citation paper in the citation database in association with the first set of information about the citation paper;
• and
• sending the first set of information and the second set of information about the citation paper to a computer device.

A computer-implemented method for constructing a citation database, comprising:

• storing a first set of information about a citation paper in a citation database;
• searching for one or more figures in the citation paper;
• extracting the one or more figures from the citation paper;
• and
• storing the one or more figures in the citation database in association with the first set of information about the citation paper.
