When a user receives potential junk e-mail from an unknown sender address, an active filter installed in or cooperating with the user's e-mail system sends a challenge e-mail back to the sender address. Unless the user receives a correct response e-mail from the sender address and/or a response that meets formal criteria, the active filter rejects the original e-mail and blocks future e-mail from that sender address. The challenge preferably includes a question that the sender must correctly answer in his response. The question is such that only humans can interpret and respond to it correctly. For example, the question may relate to and/or be incorporated in an image in the challenge. Lists of approved and blocked sender addresses are compiled. The user may directly enter addresses in the address lists. Addresses to which the user has sent e-mail may also be included directly in the approved list.

In one aspect, a system includes a transaction handler to process transactions, a data warehouse to store transaction data recording the transactions processed at the transaction handler and to store mapping data between first user identifiers and first account identifiers, a profile generator to generate a profile of a user based on the transaction data, and a portal coupled to the transaction handler to receive a query identifying a second user identifier used by the first tracker to track online activities of a user. The system is to identify a second account identifier of the user from the second user identifier based on the mapping data between the first user identifiers and the first account identifiers to facilitate targeted advertising using the profile of the user and/or to provide information about certain transactions of the user related to a previously presented advertisement.

Systems and methods to match identifiers

A system and method are provided for identifying inappropriate content in websites on a network. Unrecognized uniform resource locators (URLs) or other web content are accessed by workstations and are identified as possibly having malicious content. The URLs or web content may be preprocessed within a gateway server module or some other software module to collect additional information related to the URLs. The URLs may be scanned for known attack signatures, and if any are found, they may be tagged as candidate URLs in need of further analysis by a classification module.

System and method of analyzing web content

A method and an apparatus are used to target interactive virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects (1265) available for targeting categorized and categories are correlated to subscriber information (1210) to determine the optimum targeting of the virtual objects (1260). The virtual objects may be targeted (1220) based on individual subscriber information (1210) or on information related to a group of subscribers. When a frame of program includes a virtual object location, a default or an alternate virtual objects is displayed. The virtual object location may change over space or time. The virtual object may be interactive, and may be used to link a subscriber to a remote location, such as an Internet web site. The television terminals record which virtual objects were displayed and report this information back to the headends and the operations center. The reported information is used to generate billing for commercial advertisers and to analyze viewer watching habits.

Computer method and apparatus for extracting information from a Web page is disclosed. The invention apparatus is formed of an extractor coupled to receive Web pages from a source. The extractor uses natural language processing to extract desired information from the Web page. A storage subsystem receives from the extractor the extracted desired information and stores the extracted desired information in a database. The invention method for extracting data from a Web page includes the computer implemented steps of (i) using natural language processing, finding possible formal names on a given Web page, (ii) using pattern matching, searching the given Web page for formal names not found by the natural language processing, and (iii) refining a combined set of the found formal names to produce a working set of people and organization names extracted from the given Web page. The refining includes determining aliases of respective people and organization names, so as to effectively reduce duplicate names.

Computer method and apparatus for extracting data from web pages

Computer processing method and apparatus for searching and retrieving Web pages to collect people and organization information are disclosed. A Web site of potential interest is accessed. A subset of Web pages from the accessed site are determined for processing. According to types of contents found on a subject Web page, extraction of people and organization information is enabled. Internal links of a Web site are collected and recorded in a links-to-visit table. To avoid duplicate processing of Web sites, unique identifiers or Web site signatures are utilized. Respective time thresholds (time-outs) for processing a Web site and for processing a Web page are employed. A database is maintained for storing indications of domain URLs, names of respective owners of the URLs as identified from the corresponding Web sites, type of each Web site, processing frequencies, dates of last processings, outcomes of last processings, size of each domain and number of data items found in the last processing of each Web site.

A database is formed and maintained by computer-automated means extracting information from a global computer network. The database contains information about people and organizations. The present invention method provides continual updates to the information stored in the database by the people named in the database and by the automated means. Integrity of the automatically extracted information is maintained. A link from the invention database to a third party data system provides updates in the information in the database to be communicated to the third party data system for updating and maintaining data of the third party data system. The database may serve as an email communication clearinghouse where senders do not need to know the email address of a person named in the database but rather leaves messages through that person's record in the database. Targeted advertising to a named person is provided during his accessing the database. The targeted advertising is based on information about the named person as stored in the database. The database may be queried by any combination of person name, job title, organization name and field of business of the organization. The invention method provides clipping service which monitors changes in the information stored in the database and notifies interested parties of detected changes.

Method for maintaining people and organization information

A computer automated method and system mines from a global computer network, information about people and organizations. The system includes automated crawling means, a distributor controlling the crawling means processing, an extractor storing extracted information of interest in a database, an integrator and post-processor. The integrater resolves duplicate information and combines related information in the database. The post-processor analyzes the database contents and generates (by deduction) missing information. Also disclosed is a method and means for generating a business email address of a person named in the database, from the respective organization named in the database for the subject person.

Data mining system

Computer method and apparatus determines content type of contents of a subject Web page. A predefined set of potential content types is first provided. For each potential content type, there are one or more tests having test results that enable quantitative evaluation of the contents of the subject Web page. A respective probability of each potential content type being detected in some contents of the subject Web page is determined. A Bayesian network combines the test results to provide indications of the types of contents detected on the subject Web page. A confidence level per detected content type is also provided. A database stores the determined probabilities and confidence levels, and thus provides a cross reference between Web pages and respective content types of contents found on the Web pages.
