Abstract: A system may receive a search query. The system may further provide a list of first documents relating to the search query in a first area of a user interface and provide additional information that has been retrieved from the first documents in a second, different area of the user interface. The additional information includes an attribute name and an associated attribute value.

Abstract: A repository contains objects representing entities. The objects also include facts about the represented entities. The facts are derived from source documents. A synonymous name of an object is determined by identifying a source document from which one or more facts of the entity represented by the object were derived, identifying a plurality of linking documents that link to the source document through hyperlinks, each hyperlink having an anchor text, processing the anchor texts in the plurality of linking documents to generate a collection of synonym candidates for the entity represented by the object, and selecting a synonymous name for the entity represented by the object from the collection of synonym candidates.

Abstract: A fact repository contains facts having attributes and values and further having associated annotations, which are used, among other things, to vet facts in the repository and which can be returned in response to a query.

Abstract: A system and method for categorizing objects on the basis of the existence of the facts describing those objects. Objects may be stored in the collection regardless of their category, and each object may have any number of facts associated with it. The objects are then categorized on the basis of their data structure, that is, on the basis of the existence of the facts associated with that object.

Abstract: A system and method for maintaining persistent object identifiers across versions of a collection of data. According to one embodiment of the present invention, a first collection of objects is compared to a second collection of objects. If an object in the first collection matches an object in the second collection, a reference is added to the object in the first collection referring to the object in the second collection, allowing the identifier to persist in both collections of objects. Additionally, according to one embodiment of the present invention, the data (or “facts”) associated with the object from the first collection are moved to the object from the second collection. In this way, data associated with matching objects is combined between two collections of objects while maintaining persistent object identifiers.

Abstract: A system and method identifying duplicate objects from a plurality of objects. The system and method groups similar objects into buckets based on a selected grouper, matches objects within the same bucket based on a selected matcher, and identifies the matching objects as duplicate objects.

Abstract: A system and method determines whether two objects are duplicate objects. The system and method matches common facts of the two objects based on a match measure, combines the entropies of the matching common facts, and determines whether the two objects are duplicate objects based on the sum of entropies.

Abstract: Links between facts associated with objects are automatically created and maintained in a fact repository. Names of objects are automatically identified in the facts, and collected into a list of names. The facts are then processed to identifying such names in the facts. Identified names are used as anchor text for search links. A search link includes a-search query for a service engine which search the fact repository for facts associated with objects having the same name.

Abstract: A fact repository supports searches of facts relevant to search queries comprising keywords and phrases. A service engine retrieves the objects that are associated with facts relevant to the query. The objects are displayed on a search results page. Each object is displayed with selection of the facts associated with the object. The selected facts are ordered according to their relevance to the query.

Abstract: A system and method identifying duplicate objects from a plurality of objects. The system and method normalizes name values of objects, groups objects into buckets based at least in part on the normalized name values, matches objects within the same bucket based on a selected matcher, and identifies the matching objects as duplicate objects.

Abstract: A system and method for extracting facts from documents. A fact is extracted from a first document. The attribute and value of the fact extracted from the first document are used as a seed attribute-value pair. A second document containing the seed attribute-value pair is analyzed to determine a contextual pattern used in the second document. The contextual pattern is used to extract other attribute-value pairs from the second document. The extracted attributes and values are stored as facts.

Abstract: A system and method for corroborating a set of facts. If the anchor text of the references to a document matches the name of a set of facts, the referenced document is used to corroborate the set of facts. By analyzing the anchor text of the references to the document, the system is capable of determining if a document is relevant to the set of facts. These documents can then be used to corroborate or refute the facts, thereby improving their overall quality.
