摘要:
One embodiment of the present invention provides a system that learns a generative model for textual documents. During operation, the system receives a current model, which contains terminal nodes representing random variables for words and cluster nodes representing clusters of conceptually related words. Within the current model, nodes are coupled together by weighted links, so that if a cluster node in the probabilistic model fires, a weighted link from the cluster node to another node causes the other node to fire with a probability proportionate to the link weight. The system also receives a set of training documents, wherein each training document contains a set of words. Next, the system applies the set of training documents to the current model to produce a new model.

A computer-implemented method of providing invitations to a shared communication space, performed by a server system, includes providing the shared communication space, which includes content associated with a set of characteristics, and identifying a user, in accordance with a set of characteristics associated with the user and the set of characteristics associated with the content in the shared communication space. The method further includes sending to the identified user a invitation to participate in the shared communication space, and upon acceptance of the invitation by the user, enabling access by the user to the shared communication space by the user and enabling the user to exchange information with other participants in the shared communication space via the shared communication space.

Methods and apparatus consistent with the invention provide improved organization of documents responsive to a search query. In one embodiment, a search query is received and a list of responsive documents is identified. The responsive documents are organized based in whole or in part on usage statistics.

An instant messaging (IM) system has an IM server connected to a communication network, and logic operable on the IM server enabling a first user to browse contacts associated with a second user. In some cases the first user can add and list contacts accessed by browsing the contacts associated with the second user.

Communications between entities who may share common interests. For entities determined to be sharing common interests (e.g., searching using the same terms or topics, browsing a page, a site or a groups of topically related sites), options for communication among the entities are provided. For example, a chat room may be dynamically created for persons who are currently searching or browsing the same or related information. As another example, a “homepage” may be created for each query and contain various types of information related to the query. A permission module controls which entities may participate, what types of information (and from what sources) an entity can (or desires to) receive, what types of information the entity may (or desires to) share.

Advertisers are permitted to put targeted ads on page on the web (or some other document of any media type). The present invention may do so by (i) obtaining content that includes available spots for ads, (ii) determining ads relevant to content, and/or (iii) combining content with ads determined to be relevant to the content.
