    摘要： This invention relates to customized electronic identification of desirable objects, such as news articles, in an electronic media environment, and in particular to a system that automatically constructs both a 'target profile' for each target object in the electronic media based, for example, on the frequency with which each word appears in an article relative to its overall frequency of use in all articles, as well as a 'target profile interest summary' for each user, which target profile interest summary describes the user's interest level in various types of target objects. The system then evaluates the target profiles against the users' target profile interest summaries to generate a user-customized rank ordered listing of target objects most likely to be of interest to each user so that the user can select from among these potentially relevant target objects, which were automatically selected by this system from the plethora of target objects that are profiled on the electronic media. Users' target profile interest summaries can be used to efficiently organize the distribution of information in a large scale system consisting of many users interconnected by means of a communication network. Additionally, a cryptographically-based pseudonym proxy server is provided to ensure the privacy of a user's target profile interest summary, by giving the user control over the ability of third parties to access this summary and to identify or contact the user.

    摘要： The adaptive compression technique improves the Lempel-Ziv (LZ) technique because it reduces the required storage space (18) and transmission time with transferring data (22). Pre-filled compression dictionaries (48) are utilized to resolve prior problems with the Lempel-Ziv technique where compression software starts with an empty compression dictionary and little compression is attained until dictionary has been filled with sequences common in the data being compared. The compression dictionary (48) is pre-filled with letter sequences, words and/or phrases that are commonly found in the compressed area. They may be used in the pre-filled dictionary where they are determined by sampling text data from the same text genre. Initially, multiple pre-filled dictionaries (52) may be utilized by the software, where the most appropriate dictionary for maximum compression is identified and used to compress current data. These modifications are made to any of the known Lempel-Ziv compression techniques based on the variants detailed in 1977 and 1978 articles by Ziv and Lempel.

    摘要： The broadcast data distribution system distributes directory and indexing information for the selection of viewing choices in broadcast and multicast networks with asymmetric uplink/downlink bandwidths. Examples of such systems include Digital Broadcast Satellite (DBS) and Cable Television (CATV) systems. More particularly, a preferred embodiment of the invention co-locates shared directory resources at directory servers which can provide the benefit of technology improvement through storage multiplexing to directory clients, which are assumed to have smaller, more heterogeneous and slowly-evolving memory and processing resources. The directory information stored at the directory clients is a subset of the information maintained at the directory servers selected on the basis of subscriber interest. This system automatically constructs both a target profile for each target object (program) that is broadcast, as well as a 'target profile interest summary' for each subscriber, which target profile interest summary describes the subscriber's interest level in various types of target objects. The system then evaluates the target profiles against the subscriber's target profile interest summaries to generate a subscriber-customized rank ordered listing of target objects most likely to be of interest to each subscriber, so that the subscriber can select from among these potentially relevant target objects, which were automatically selected by this system from the plethora of target objects available on the data distribution system.
