Assigned to Yahoo! Inc.

Abstract

A system and method is provided for qualifying search listings for placement in at least one search result list and ordering the search listings according to an algorithm. Specifically, a searching device is adapted to received items of information, such as search listings (e.g., www.yahoo.com, etc.), search terms (e.g., “cars,” “beauty supplies,” etc.) and monetary amounts (e.g., $1.00, etc.), from a plurality of promoting devices, receive a search inquiry (i.e., a search term) from a reception device, and provide (in response thereto) at least one search result list including search listings (i) associated with the search inquiry and (ii) qualified for placement in the search result list. In other words, if the search term linked to the search listing is the same as (or substantially similar to) the search inquiry, then the first prong is met. Furthermore, if a predetermined number of monetary amounts (i.e., as linked to a predetermined number of search listings associated with the search inquiry) are not higher than the monetary amount linked to the search listing, then the second prong is met and the search listing is qualified for placement. Thus, only a predetermined number of search listings (e.g., three, five, etc.) that are both (i) associated with the search inquiry and (ii) linked to the highest monetary amounts are qualified for placement in the search result list. Once the search listings are qualified for placement in the search result list, the searching device is adapted to arrange the qualified search listings according to an algorithm (e.g., randomly, according to relevance, according to monetary amounts, etc.).

Outbound information analysis for generating user interest profiles and improving user productivity

Inventors: Matthias Eichstaedt, Qi Lu, Shang-Hua Teng
Assignee: International Business Machines Corporation
US Patent 6,654,735
Granted November 25, 2003
Filed January 8, 1999

Abstract

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.

Assignee: International Business Machines Corporation
US Patent 6,480,830
Granted November 12, 2002
Filed March 27, 1998

Abstract

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.

Automatic user interest profile generation from structured document access information

Inventors: Matthias Eichstaedt, Qi Lu, and Shang-Hua Teng
Assignee: International Business Machines Corporation
US Patent 6,385,619
Granted May 7, 2002
Filed January 8, 1999

Abstract

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.

Filed October 8, 1998

Abstract

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.

US Patent 6,169,989
Granted January 2, 2001
Filed May 21, 1998

Abstract

A method and apparatus for efficiently matching a large collection of user profiles against a large volume of data in a webcasting system. The invention generally includes in one embodiment four steps to parallelize the profiles. First, an initial profile set is partitioned into several subsets also referred to as sub-partitions using various heuristic methods. Second, each sub-partition is mapped onto one or more independent processing units. Each processing unit is not required to have equal processing performance. However, for best performance results, subset data should be mapped in one embodiment where the subset with a highest cost is mapped to a fastest processor, and the next highest cost subset mapped to the next fastest processor. Where appropriate, the invention evaluates the relative subset processing speed of each processor and adjusts future subset mapping based upon these evaluations. For each information item I that needs to be matched with a profile predicate, a third and a fourth step are executed. The third step broadcasts I to all processing units, and a fourth step performs a sequential profile match on I.

System for creating structured fields on electronic forms

Inventors: Reiner Kraft, Qi Lu, and Ron Yair Pinter
Assigned to International Business Machines Corporation
US Patent 6,137,488
Granted October 24, 2000
Filed July 29, 1998

Abstract

A computer system enables a user to conveniently fill-out, configure, and submit a structure of interrelated data fields, where the order and type of linking between the fields is user selected. A graphical user interface presents a field template having one or more data fields. The user may extend the electronic form by selecting an expand form field; in response to selection of the expand field, the user interface adds a second field template and a connective field to the display. This second template, like the first, includes one or more data fields. Using a connective field, the user identifies a logical relationship between the first field template and the second field template. For instance, the user may select from Boolean or other connective terms to construct a form having a complex format of interrelated fields. As each new field template is added with its corresponding connective field, the user interface also presents a nesting icon, allowing the user to establish a logical hierarchy between the various field templates.

Task distribution processing system and the method for subscribing computers to perform computing tasks during idle time

Inventors: Reiner Kraft, Qi Lu, and Marat Wisebond
Assigned to International Business Machines Corporation
US Patent 6,112,225
Granted August 29, 2000
Filed March 30, 1998

Abstract

A computer executable “aggregate” task is processed by dividing it into subtasks and distributing the subtasks “on demand” to remotely located subscribing computers via a computer network. The aggregate task originates at a coordinating computer, coupled to one or more peripheral computers by appropriate communications links. The coordinating computer divides the aggregate task into multiple independent subtasks. Each peripheral computer begins to “subscribe” to the coordinating computer’s aggregate task by obtaining an “idle time activation program” from the coordinating computer, and then installing the program locally. The idle time activation program which may include a screen saver, activates automatically when the subscribing computer is inactive. Continuing the subscription process, each peripheral computer requests a subtask from the coordinating computer. In response, the coordinating computer distributes different subtasks among the subscribing computers, completing the subscription process. The subscribing computers automatically work on their respective subtasks whenever they are idle, as directed by the local idle time activation program. When a subscribing computer completes its subtask, it transmits results back to the coordinating computer. When results of all subtasks have been received from subscribing computers, the coordinating computer compiles and stores these results, concluding the aggregate task.

Method and apparatus for efficient profile matching in a large scale webcasting system

Inventors: Matthias Eichstaedt and Qi Lu
Assigned to International Business Machines Corporation
US Patent 6,108,645
Granted August 22, 2000
Filed November 26, 1997

Abstract

A method and apparatus for efficiently matching a large collection of user profiles against a large volume of data in a webcasting system. The method removes redundant patterns in user profiles and information content to improve matching performance based on a Boolean-based query language. Users can select desired information content by choosing a set of predicates to assert the properties for each cyberspace document desired. Boolean operators of AND, OR and NOT connect predicates together on the information items that will be pushed to them. The method includes dynamic cost/credit adjustment based profile indexing and matching.

System for directly accessing fields on electronic forms

Inventors: Reiner Kraft, Qi Lu, and Ron Yair Pinter
Assigned to International Business Machines Corp.
US Patent 6,084,585
Granted July 4, 2000
Filed July 29, 1998

Abstract

A computer system provides a graphical user interface (GUI) to assist a user in completing electronic forms. The computer includes components such as a processor, user interface, and video display. Using the video display, the processor presents a row entry template including a menu field and an associated data field. The user completes the menu field by selecting a desired menu entry from a list of predefined menu entries. The user completes the data field by entering data into the data field. This format is especially useful when the data entry provides data categorized by the menu entry, explains the menu entry, or otherwise pertains to the menu entry. Each time the GUI detects activation of a form expand key, it presents an additional row entry template for completion by the user. Upon selection of a submit key, data of the completed form is sent to a predefined destination, such as a linked list, table, database, or another computer. Thus, by planned selection of menu entries, the user can limit his/her completion of an electronic form to blanks applicable to that user, avoiding the others. Nonetheless, the form can be easily expanded row by row to accommodate as many different blanks as the user wishes to complete. The invention may be implemented by a host sending a remote computer machine-executable instructions which the remote computer executes to provide the GUI, where the remote computer ultimately returns the completed form data to the host.

Audio ticker system and method for presenting push information including pre-recorded audio

Inventors: Qi Lu and Lev Stesin
Assigned to International Business Machines Corporation
US Patent 6,035,336
Granted March 7, 2000
Filed October 17, 1997

Abstract

For use with client/server or network communication and processing systems, such as the Internet, a “push” information system is provided, for automatically providing information to a user. The information is provided in audio form. The system includes a library of prerecorded sounds, including a dictionary of words and phrases. When information appears, for instance in text format, a mapper produces a sequence of audio clips from the library, to convey information substantially identical to that in the information. This sequence of audio clips is played at the user’s terminal. Thus the user is exposed to the information, while the user continues to use an application on the terminal. The information does not require screen real estate, and the user need not look away from his/her work in order to receive the information.
