摘要： Systems and methods for analyzing HTML formatted web pages to automatically identify and extract desired information. A computer algorithm identifies and extracts different pieces of information from different web pages automatically after minimal manual setup. The algorithm automatically analyzes pages with different content if they have the same, or similar, formats. The algorithm is fast and efficient and performs the extraction process quickly in real-time. The systems and methods are useful to build databases from unstructured web information. The algorithm can be used as an agent that captures information about products, and compares prices or other characteristics. It can also be used to populate structured databases that, given the different pieces of information, can analyze products and their characteristics. And it can also be used for data mining applications looking for patterns useful for marketing analyses, or other uses.

摘要： An “active” calendar automatically analyzes a user's calendar entries and sends machine-readable messages to destinations appropriate to content of the calendar entry. A group of event categories is established, each category specifying one class of anticipated calendar entry. An action rule database pre-associates each event category with one or more message formats each having a content and a destination. The action rule database also contains data identifying sources containing the content and destination for each message format. These sources include records of the action rule database itself, subparts of calendar entries of the pre-associated event category, one or more other databases, or a combination of the foregoing. After the calendar receives a user-submitted computer calendar entry describing a planned event, it identifies one of the event categories of the established group that classifies the planned event. For each message format pre-associated with the identified event category, the calendar determines the content and destination for the message as specified by the action rule database, and transmits the message to the destination.

摘要： A distributed collection of web-crawlers to gather information over a large portion of the cyberspace. These crawlers share the overall crawling through a cyberspace partition scheme. They also collaborate with each other through load balancing to maximally utilize the computing resources of each of the crawlers. The invention takes advantage of the hierarchical nature of the cyberspace namespace and uses the syntactic components of the URL structure as the main vehicle for dividing and assigning crawling workload to individual crawler. The partition scheme is completely distributed in which each crawler makes the partitioning decision based on its own crawling status and a globally replicated partition tree data structure.

摘要： A tactile notification device that can be embodied in, e.g., a wristwatch, communicates via wireless link with plural personal computing devices, including cellular telephones, pagers, and palm top computers, of the person wearing the notification device. When one of the personal computing devices alerts, e.g., when the telephone receives an incoming call, the pager receives a page, or the palm top computer receives an email, the personal computing device sends a signal to the notification device, which generates a discrete tactile signal against the person's skin. The notification device can generate different tactile signals, and each tactile signal can be correlated as desired by the user to one of the personal computing devices. In one embodiment, opposed pinch bars are provided on the skin-facing tactile surface of a wristwatch to gently pinch the skin and thereby establish a first tactile signal that can be correlated to, for example, an alert for an incoming phone call. Also, a rotating bar can be provided on the tactile surface of the wristwatch, and the tactile signal that corresponds to, e.g., an incoming page can be established by rotating the bar against the skin.

摘要： A system for automatically generating user interest profiles and delivering information to users learns a user's interests by monitoring the user's outbound communication streams, i.e., the information that the user produces either by typing (e.g., while a user is composing an e-mail message or editing a word processor document) or by speaking (e.g., while a user is engaged in a phone conversation or listening to a lecture). The system uses the monitored text to build (and possibly update) a user interest profile. The profile is constructed from current text generated by the user, so that the retrieved information reflects present user interests. In addition, the profile may also retain past user interests, so that the profile reflects a combination of past and present user interests. The system then automatically queries diverse databases for information relevant to the interest profile. The databases may include internet web pages, files stored on the user's local network, and other local or remote data repositories. The queries may use a combination of internet search engines, the specific selection of which may depend upon the nature and/or content of the queries. The information retrieved in response to the queries is then presented to the user. The retrieved information may contain, for example, answers to questions that the user might ask and/or data related to the user's current and continuing interests. Because a user's current speech or typed text is highly correlated with the user's current interests, the retrieved information will be relevant to the user's actual interests. The communication stream monitoring, interest profile building, data base querying, and presentation of retrieved information are all performed automatically, in real time, and in the background of current user activities.

摘要： A stylus includes a wireless transceiver, a processor controlling the transceiver, and a data storage device. Data can be selected on a first computer such as a first personal digital assistant (PDA) and then transmitted via wireless link to the stylus, when the user manipulates a button on the stylus to signal to the operating system of the first PDA that it is ready to receive data. The data is transmitted to the stylus and stored therein. Then, the stylus is aimed at a second PDA and the button is manipulated to cause the stylus to transmit the data to the second PDA via wireless link. With this invention, users of the PDAs can, e.g., quickly and efficiently exchange business cards electronically, without excessive manual data entry and without resorting to connecting their PDAs to a network.

摘要： A system generates user interest profiles by monitoring and analyzing a user's access to a variety of hierarchical levels within a set of structured documents, e.g., documents available at a web site. Each information document has parts associated with it and the documents are classified into categories using a known taxonomy. The user interest profiles are automatically generated based on the type of content viewed by the user. The type of content is determined by the text within the parts of the documents viewed and the classifications of the documents viewed. In addition, the profiles also are generated based on other factors including the frequency and currency of visits to documents having a given classification, and/or the hierarchical depth of the levels or parts of the documents viewed. User profiles include an interest category code and an interest score to indicate a level of interest in a particular category. The profiles are updated automatically to accurately reflect the current interests of an individual, as well as past interests. A time-dependent decay factor is applied to the past interests. The system presents to the user documents or references to documents that match the current profile.
