SUMMARY OF THE INVENTION

[0007] Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth herein.

[0008] In one aspect of the invention, a method of processing content created by a user utilizing a semantic, ontology-driven portal on a computer network is described. The semantic portal application provides the user with a content base, such as a semantic form or meta-form, for creating a semantic posting. The semantic portal utilizes a knowledge data structure, such as a taxonomy or ontology, in preparing a semantic posting based on the information provided by the user via the content base. The semantic portal application prepares a preview of a semantic posting for evaluation by the user. The semantic posting is then either modified by the user or accepted and posted by the user for external parties to view.

[0009] In another aspect of the invention, a method of sharing information on a semantic-based network is described. A semantic portal application intercepts an e-mail message via an outgoing mail server or an incoming mail server. It then creates a semantic object from the e-mail message by examining syntax of the e-mail message inline, for example by detecting brackets, colons, and certain keywords indicating data type. The semantic posting is then make viewable by the public.

[0295] In addition to the above, Hotnode does automatic social networking: Building a social network by simply analyzing the recipients on messages, and linking these together into a representation of the social network that they are a result of. This is a secondary viral feature: Belonging to such a network makes it more likely that a member will solicit his or her friends to join the network. Hotnode looks at the user's emails as they come through and builds a social network from them automatically, based on who they correspond with. The user can then search, visualize and communicate using this network. This is totally automatic--there is no need to send or reply to "join my network" messages anymore. Hotnode learns just by seeing who talks to who.

[0298] We are going to start by providing a the most powerful hosted blogging and wiki service on our platform, as well as a portal for our community of users. We provide semantic blogging, Website and Wiki services to individuals, groups, communities and organizations. We are the semantic equivelent of the Wikipedia or Everything2 (which we might consider acquiring or close collaboration with). Users get a basic blog and Wiki for free, without ads. We can also provide them with other semantic objects they can post to their blogs for various types of things. If a user accept ads then they get some additional free features. Users can opt-in to advanced features by subscribing to the Hotnode Pro service ($9.95/month) and paying a la carte fees for other optional additions.
