A human viewing temporally-dimensioned content of a multimedia document through use of a computer can add substantive content to temporally-dimensioned content of the multimedia document to thereby annotate, comment upon, and augment the multimedia document. Thus, a multimedia document becomes a basis for collaborative work. The substantive content added by the viewing user is in the form of a temporal annotation which identifies a particular relative time in temporally-dimensioned content of the multimedia document and which includes user-authored content provided by the viewing user. Display of the multimedia document includes presentation of the temporal annotations created by the user. A graphical user interface enables the user to select a temporal annotation from a list and immediately proceed to presentation of the multimedia document such that temporally-dimensioned content is presented at the particular relative time represented by the selected temporal annotation. In addition, as temporally-dimensioned content of the multimedia document is displayed, temporal annotations are represented in the display of the multimedia document as the particular relative time represented by each temporal annotation is reached. Thus, the user-authored content becomes part of the display of the multimedia document in a temporal context.

The method recited in claim 1, further comprising the steps of: generating a training word list (TWL) for the current category based upon the RWL for the pre-stored information already in the current category; and calculating the relevance factor (RF) based upon the RWL and the TWL. 3. The method recited in claim 2, wherein the RF is calculated according to the following algorithm: RF=(100*X)/Y, where X=number of words present in the RWL that are not in the TWL, and Y=number of words in the RWL. 4. The method recited in claim 1, further comprising the steps of: if the stored information is added to the current category, adding the words from the RWL to the TWL for the current category. 5. The method recited in claim 1, wherein if the stored information is added to the current category, further comprising the steps of: creating a most frequent word list (MFWL) consisting of the words in the RWL ranked by order of occurrence; identifying sentences in the stored information containing one or more of the highest ranked words in the MFWL; and creating a summary of the stored information based upon the identified sentences. 6. A system for managing information in a computer network comprising: an interconnection network; a plurality of client nodes coupled to the interconnection network; a plurality of information provider nodes coupled to the interconnection network; a system server coupled to the interconnection network; a database coupled to the system server containing pre-stored information from the information provider nodes; means for autonomously gathering change data from the information provider node indicative of event changes at the information provider node relative to the pre-stored information the database; extracting information from the information provider node based on the change data; means for autonomously extracting information from the information provider nodes based upon the change data; means for autonomously coordinating the extracting of information by the extracting means and for autonomously transmitting the extracted information to the system server via the interconnection network; means located at the system server for cataloging the extracted information transmitted from the coordinating means, wherein means for cataloging is comprising: means for generating a common word list (CWL) consisting of words that occur most often in a sample set of the pre-stored information; means for generating a relevant word list (RWL) consisting of all words in the extracted information not in the CWL; means for calculating a relevance factor (RF) indicative of the relevance of the extracted information to a current hierarchical category, based upon the RWL; means for comparing the RF to a relevance threshold (RT); and if the RF exceeds the RT, adding the extracted information to the current category. 7. The system recited in claim 6, further comprising: means for generatin g a training word list (TWL) for the current category based upon the RWL for the pre-stored information already in the current category; and means for calculating the relevance factor (RF) based upon the RWL and the TWL. 8.
