Electronic data files are broadly characterized as “messages” and a social network is constructed by analyzing one or more messages exchanged between various entities. Additionally, messages from structured and / or unstructured data stores are correlated using one or more common / related data elements from two or more messages. Further, the social network and the concepts contained in the exchanged messages (i.e. semantic network) can be visualized using a series of multi-aspect viewing tools. Finally, in conjunction with the social network and the semantic network, a message network based on the chronological relationship of the messages (event network) can be constructed to analyze and visualize how the messages relate to each other in a time-based reference model. Once visualized, the relationship of the concepts contained in the messages as well as the relationship between the entities and the timing involved in the exchange of messages can be analyzed for desired information.

User authentication apparatus controlling access to systems, inputs owner's login name and password and then extracts the owner's timing vectors from keystroke characteristics with which the owner forms a training set. A semantic network uses multiple links to indicate that different pattern components of user's behavioral access create different kinds of relationships and “symbolic representations”. A neural network is trained by using each of the owner's timing vectors in the training set as an input. When a user inputs the owner's login name and password, it's checked and the user's timing vector is extracted to type the user's password if checked and demoted in confidence level if otherwise. The user's timing vector is applied to neural network and difference between the input / output is compared with a predetermined threshold; and if the difference is greater than the threshold, is prohibited. Preferably this is aided by response time to personal questions.

A computer implemented method, data processing system, and computer program product for establishing document relevance by semantic network density. When a search query is received, one or more semantic networks are identified which contain nodes matching one or more terms in the search query. An edge density is determined for each node matching a term in the search query. A relevancy score is then calculated for each of the one or more semantic networks based on the edge densities of the nodes matching a term in the search query. Based on the relevancy score, the relevancy to the search query of a document associated with the one or more semantic networks may then be determined.

A social semantic network provides for the efficient distribution of digital objects between users of that network. People in the network are connected by labeled edges that define relationships. Any person can create content in the form of particles, and by labeling that content, can determine how that content is distributed through the network. Labeled particles travel through each node in the network based on comparisons of the particle label with each edge label when exiting that node. Propagation can be controlled by the person at each node through which the particle travels or, alternatively, the system can be adapted to propagate particles one or two nodes at a time. Thus, a decentralized push-based system for distributing content is achieved without extensive regulation of that which is “appropriate” for consumers.
