Abstract: Demographic information of an Internet user is predicted based on an analysis of accessed web pages. Web pages accessed by the Internet user are detected and mapped to a user path vector which is converted to a normalized weighted user path vector. A centroid vector identifies web page access patterns of users with a shared user profile attribute. The user profile attribute is assigned to the Internet user based on a comparison of the vectors. Bias values are also assigned to a set of web pages and a user profile attribute can be predicted for an Internet user based on the bias values of web pages accessed by the user. User attributes can also be predicted based on the results of an expectation maximization process. Demographic information can be predicted based on the combined results of a vector comparison, bias determination, or expectation maximization process.

Abstract: A system (10) and method of caching uses quality or value attributes, provided for example, by a recommender system (16) or by a dynamical analysis of site accesses, which are attached to cached information to prioritize items in the cache (24). Documents are prioritized in the cache according to the relative value of their content. Value data may be provided from a recommender system (16) which provides a value for a document according to user recommendations (using explicit recommendations) or from statistical analysis of site visits from unique users (implicit recommendations) or a combination of the two to identify the higher value documents. The caching method may also be used to improve performance of a recommender system (16).

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system usable for predicting user profile information from Web usage. SOLUTION: A machine-implemented method for predicting the user profile information from web page access patterns of a user comprises: a step of detecting a set of web pages accessed by the user; a step of mapping at least a subset of the web pages to a first data structure, the first data structure identifies the web page access pattern of the user; a step of comparing the first data structure to a second data structure to obtain a comparison result, the second data structure identifies the web page access pattern of a set of known users, the known users having a user profile attribute in common; and a step of assigning the user profile attribute to the user in response to the comparison result.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for optimizing the resources of an end user or a network in a network system including caching. SOLUTION: A caching system 10 attaches quality or a value characteristic provided by a recommender system 16 or the dynamic analysis of a site access to cache information in order to set up the priority of items in a cache 24. Priority is allocated to respective documents in the cache on the basis of the relative values of respective contents. Value data can be provided from the recommender system 16 for providing the value of each document on the basis of user's recommendation (using suggestive recommendation), the statistic analysis (suggestive recommendation) of a site access by an inherent user or the combination of these two procedures in order to specify a document having a high value.
