An information retrieval system allows a user to search a database of informational items for a desired informational item, and presents the search result in the form of matching index entries in the order of relevance. The information retrieval system in accordance with the principles of the present invention assigns a relevance rating to each of the index entries without requiring an explicit input from the user with respect to the usefulness or the relevance of the retrieved information corresponding to the respective index entries. When the user selects and retrieves an informational item through a list of index entries presented by the retrieval system, as a result of a search, the relevance rating of the selected informational item is increased by a predetermined amount. The relevance rating of the selected informational item is further adjusted based on any actions the user takes subsequent to the initial selection of the informational item if the subsequent act indicates that the relevance of the selected informational item may be less than what is reflected by the rating increase by the predetermined amount. Ratings of the informational items in the database are determined from implicit suggestions from the usage of the retrieval system and the database by the user rather than from an explicit user input. In another aspect of the present invention, the ratings are allowed to decay over time to minimize the tendencies for historical usage biased rating, and to provide more temporally accurate ratings. The most recently accessed time of each of the informational items in the database is compared to a predetermined stale access time threshold, and if the most recently accessed time is older than the threshold, than the rating of the corresponding informational item is decreased to reflect the dated nature of the information contained within the item.

A process and system for database storage and retrieval are described along with methods for obtaining semantic profiles from a training text corpus, i.e., text of known relevance, a method for using the training to guide context-relevant document retrieval, and a method for limiting the range of documents that need to be searched after a query. A neural network is used to extract semantic profiles from text corpus. A new set of documents, such as world wide web pages obtained from the Internet, is then submitted for processing to the same neural network, which computes a semantic profile representation for these pages using the semantic relations learned from profiling the training documents. These semantic profiles are then organized into clusters in order to minimize the time required to answer a query. When a user queries the database, i.e., the set of documents, his or her query is similarly transformed into a semantic profile and compared with the semantic profiles of each cluster of documents. The query profile is then compared with each of the documents in that cluster. Documents with the closest weighted match to the query are returned as search results.

The present invention is directed to a computer-implemented method and apparatus for searching in response to Internet-based search queries using a search engine and an electronic database. According to one example embodiment of the present invention, data sets representing published items are input, for example, scanned-in or sent electronically, and stored in a searchable database. Each data set includes text from at least one published item. Responsive to the search query, a search engine searches for and identifies relevant web pages and data sets representing published items and, in a more specific embodiment, ranked characterizations are returned for the relevant web pages and published items. An electronic path can be provided with the published item for accessing further information about the published item. In one embodiment, the electronic path is a hyperlink from a characterization of a relevant published item to a more complete electronic representation of the relevant published item. Publishers provide authorization to display copyrighted materials through a permission protocol.

A content-based method of managing a collection of documents is disclosed. A user interface is provided for managing the collection of documents. For each document, at least one information object representative of conceptual content of a portion of the document is identified. The information objects are combined with additional conceptual information inferred from the user interface to determine a network of conceptual relationships associated with the collection of documents. The user interface provides user access to the network of conceptual relationships to manage the collection of documents.

In the present invention, a textual document is syntactically analyzed and knowledge is constructed from a single word or plural words. The knowledge is then marked, from the broken down knowledge (represented by the underscores in FIG. 1) or from a part-of-speech, as a related object (node) or a relation (edge) (represented by ‘n’ or ‘e’ shown in FIG. 1). In other words, in the present invention a textual document is treated as knowledge constructed from a single word or plural words. The knowledge extracted from the textual document is structured to form a knowledge structure (such as a graph structure constituted from nodes and edges). At least one link can be established between each of the knowledge structure elements and a semantically closest concept entry in a hierarchical concept dictionary.

A system and method lets a user create or import ontologies and create databases and related application software. These databases can be specially tuned to suit a particular need, and each comes with the same error-detection rules to keep the data clean. Such databases may be searched based on meaning, rather than on words-that-begin-with-something. And multiple databases, if generated from the same basic ontology can communicate with each other without any additional effort. Ontology management and generation tools enable enterprises to create databases that use ontologies to improve data integration, maintainability, quality, and flexibility. Only the relevant aspects of the ontology are targeted, extracting out a sub-model that has the power of the full ontology restricted to objects of interest for the application domain. To increase performance and add desired database characteristics, this sub-model is translated into a database system. Java-based object-oriented and relational application program interfaces (APIs) are then generated from this translation, providing application developers with an API that exactly reflects the entity types and relations (classes and methods) that are represented by the database. This generation approach essentially turns the ontology into a set of integrated and efficient databases.

In a database file management system for accessing data records that correspond to items in a directory. The directory items are linked to a trie index that is arranged in blocks and being stored in a storage medium. The trie index enables accessing or updating the directory items data records by key or keys and being susceptible to an unbalanced structure of blocks. There is provided a method for constructing a layered index arranged in blocks, which includes the steps of providing the trie index and constructing a representative index over the representative keys of the trie index. The layered index enables accessing or updating the directory items by key or keys and it constitutes a balanced structure of blocks.

Techniques for obtaining data from unstructured data for a structured data collection include receiving unstructured data that includes text; identifying an attribute associated with a structured data collection; obtaining at least one of historical data associated with the attribute or additional data associated with a user of the computing system; identifying one or more terms from the unstructured data as being associated with the attribute based on at least one of the historical data or the additional data; and storing the identified one or more terms in a data record of the unstructured data collection.

An information retrieval system is described that dynamically prioritizes search request results prior to output to a user. When a database search yields multiple hits, the results are first categorized into a series of groups. Categories are determined from any number of different factors, such as geographical locations of the search results, amenities, hours of operation, etc. For each category, the search results can be parsed into groups within the category. The results are first reported to the user in general terms, as a number of search results in each of the groups. The user is prompted to select the group that is of most interest, and the portion of the individual search results that are within the selected group are reported.

A system allows a user to submit an ambiguous search query and to receive potentially disambiguated search results. In one implementation, a search engine's conventional alphanumeric index is translated into a second index that is ambiguated in the same manner as which the user's input is ambiguated. The user's ambiguous search query is compared to this ambiguated index, and the corresponding documents are provided to the user as search results.

An electronic search is automatically initiated when a cursor hovers in one location for a predetermined time. A target process associated with a target window is forced to re-render data to the target window in an update region that includes the detected cursor location. From the re-rendered data, a primary word and context words near the cursor location are determined. One or more local or remote electronic data stores are searched for substantive content related to the words. The content is prioritized according to user preference and displayed in a semitransparent window that is persistently visible to a user, yet does not obscure other content in an underlying window and does not shift the focus from an active window. Re-rendering is accomplished by invalidating an update region of the target window, and forcing the operating system to issue a paint message, causing the target process to redraw the update region.

Ad information, such as ad targeting keywords and/or ad creative content for example, may be determined using aggregated selected document-to-query information associations. For example, popular terms and/or phrases also associated with a selected document may be used as ad targeting keywords and/or ad creative content for an ad having the document as a landing page. Query information may be tracked on a per document level, a per domain level, etc. The determined ad information may be used to automatically populate an ad record, or may be provided to an advertiser as suggested or recommended ad information.

Methods, systems, and articles of manufacture for indexing annotations made for a variety of different type (i.e., heterogeneous) data objects are provided. A set of parameters uniquely identifying an annotated data object may be converted to an index comprising a set of index values, each corresponding to a column in a homogeneous index table. In order to accommodate the indexing of heterogeneous data objects, a mapping may be provided for each different type (or classification) of data object that may be annotated, that defines how the identifying parameters of that type will be mapped to the columns of the homogeneous index table.

A method of constructing a profile comprising terms indicative of a characteristic of an entity commences when first electronic mail address, associated with a first entity, is created within a knowledge management system. The electronic mail address may be created automatically upon submission of an electronic mail document, or may be created manually by a systems administrator. A first electronic document is received via an electronic communications network at the first electronic mail address from a second entity, typically a user of the knowledge management system who is a registered and interactive user. The first electronic document is then parsed to identify profile terms therein. These profile terms are included within a first profile for the first entity. In this way, users of a knowledge management system may construct a profile of an entity (e.g., a customer) that is not a user of or participant within the knowledge management system.

A method and apparatus is provided for extracting key terms from a data set, the method includes identifying a first set of one or more word groups of one or more word that occur more than once in the data set, and removing from this first set a second set of word groups that are sub-strings of longer word groups in the first set. The remaining word groups are key terms. Each word group is weighted according to its frequency of occurrence within the data set. The weighting of any word group may be increased by the frequency of any sub-string of words occurring in the second set and then dividing each weighting by the number of words in the word group. This weighting process operates to determine the order of occurrence of the word groups. Prefixes and suffixes are also removed from each word in the data set. This produces a neutral form of each word so that the weighting values are prefix and suffix independent.

A system and method for searching recorded speech is disclosed. The system and method comprises converting the recorded speech into text using a voice recognition system. As the speech is being converted, naturally occurring breaks in the languages will be used to take time indexes from the recording. The system and method includes creating a full text index of the recorded speech utilizing an information extender. The full text index contains a plurality of time stamps that point to the occurrence of words in the recorded speech. Finally, the text is searched by a full text search server that has linguistic search capabilities using the full text index. Finally, the searched text, the text index and the recorded speech are stored in the database. The recorded speech is searched by locating relevant phrases or words, and then mapping the time stamps associated with the relevant phrases words back to the recorded speech in the database.

A method and apparatus for dynamically providing a path through a network of nodes or granules may use a limited, advanced look at potential steps along a plurality of available paths. Given an initial position, at an initial node or granule within a network, and some destination node or granule in the network, all nodes or granules may be represented in a connected graph. An apparatus and method may evaluate current potential paths, or edges between nodes still considered to lie in potential paths, according to some cost or distance function associated therewith. In evaluating potential paths or edges, the apparatus and method may consider extrinsic data which influences the cost or distance function for a path or edge. Each next edge may lie ahead across the advancing "partial" wavefront, toward a new candidate node being considered for the path. With each advancement of the wavefront, one or more potential paths, previously considered, may be dropped from consideration. Thus, a "partial" wavefront, limited in size (number of nodes and connecting edges) continues to evaluate some number of the best paths "so far." The method deletes worst paths, backs out of cul-de-sacs, and penalizes turning around. The method and apparatus may be implemented to manage a computer network, a computer internetwork, parallel processors, parallel processes in a multi-processing operating system, a smart scissor for a drawing application, and other systems of nodes.

A method and apparatus automatically build a database by automatically assigning links to an expert, pushing content to an expert, providing expert annotation, and linking the content to an annotation database. A term is selected by applying rules, such as, the term not previously existing in the database, an unusually high frequency of the term, the term is an article or the term is an unusual part of speech. An advertiser can sponsor the term, for example, by having a banner ad automatically pop-up on a keyword search. Content windows can be attached to the term, the content window containing information such as definitions, related products or services, sponsorship information, information from content syndicators, translations and reference works.

A method for managing objects for users including providing a set of attributes and a set of containers each having attributes from the set. The method further provides a user interface for dynamically assigning attributes to the objects. The method further provides for selectively displaying, through a user interface, containers and objects in the containers. An object is displayed in a container if a condition is met. The condition is applied to the attributes of the container and the attributes of the object.
