Link relation

Abstract: A method is described for creating and managing a two-level hierarchical data structure. Parent and child object relation tables, an aggregate relation table and a link relation table having records are created wherein each link relation record has an aggregate identity field and a child object identity field and the aggregate relation records have a parent object identity field pointing to a parent object relation record. The link relation records have an aggregate identity field pointing to an aggregate relation record and to a child object relation record whereby zero or more child object relation records are linked to a parent object record relation record.

Abstract: PROBLEM TO BE SOLVED: To handle a document printed on paper without requiring a personal computer and its program software, etc., requiring any knowledge of an HTML, and paying an attention to a uniform resource locator(URL), and to automatically generate a hyperlink with ease in a visually and an intuitively easy-to- understand style. SOLUTION: A digital plane paper copier(DPPC) 4 reads in a registration destination indication sheet 10 and a home page constituting document 8... and outputs a link relation indication sheet, reads in a link relation indication sheet 7a prepared by handwriting a link relation on the link relation indication sheet 7 and calculates differences between the previously outputted link relation indication sheet 7 and inputted link relation indication sheet 7a to recognizes the link relation indicated by the handwriting as an image, and automatically generate a hyperlink between one area and one area in the image according to the recognition result. Then the DPPC 4 performs conversion to the HTML according to the hyperlink, automatically registers a WWW home page in a cache server 3, and outputs a registration completion certificate sheet 9 as the registration result.

Abstract: PROBLEM TO BE SOLVED: To provide display in which connection of web documents in terms of a content is easily understandable even if a link destination that link description shows is redirected. SOLUTION: A crawler 10 repeats processing for detecting link description in the web document and acquiring the document of the link destination that description shows. Thus, information showing a link relation between the documents based on link description is constructed in a link information storage part 16. When a redirect detecting part 12 detects that the document of the link destination is redirected at the time of the acquiring processing of the crawler 10, it registers redirect information showing a pair of a source and a destination of the redirect to a redirect information storage part 18. A virtual link processing part 20 adds a virtual link to the redirect destination from the link source when redirect having the redirect source matched with the link destination of a link in the link information storage part 16 exists in the redirect information storage part 18.

Abstract: PROBLEM TO BE SOLVED: To grasp link relation started from a hypermedia document file designated by a user by hierarchically displaying that link relation into list. SOLUTION: When 'link list' is requested at a client computer 20 by the input operation of user using an input device 25, a link list setting dialogue is displayed on a display device 22 by a display managing part 211. When any uniform resource locator(URL) showing any arbitrary HTML file is set into a link display file setting field inside this dialogue, a list managing part 213a in a processing part 213 acquires the HTML file shown by that URL while using a network managing part 214 or a document managing part 215, analyzes the relevant file by using an HTML analytic part 213b and collects it into one body structure showing the link list. Based on this link list body structure, the display managing part 211 displays the link list for showing the link relation of the relevant file in hierarchical structure.
