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. The repository responds to requests from object requesters by sending a feed containing matching facts from the repository and, optionally, facts associated with the same object as the matching facts.

Abstract: A presentation engine presents facts in a UI having a graph. Through manipulation of the UI, an end-user can add or remove facts from the graph, and can sort the facts shown in the graph based on values that are shown, or not shown, in the graph. The presentation engine determines a graph type that best facilitates interpretation of the facts by the end-user and automatically creates a graph of that type. Possible graph types include bar graphs, scatter plots, timelines, and maps.

Abstract: A fact repository stores objects. Each object includes a collection of facts, where a fact comprises an attribute and a value. A set of objects from the fact repository are designated for analysis. The presentation engine presents the facts of the objects in a user interface (UI) having a table. Through manipulation of the UI, an end-user can add or remove facts from the table, and sort the table based on the values of particular facts. The presentation engine also presents the facts of the objects in a UI having a graph. Through manipulation of the UI, the end-user can add or remove facts from the graph, and can sort the facts shown in the graph based on values that are shown, or not shown, in the graph. The presentation engine can further present the facts of the objects in UIs including maps and timelines.

Abstract: A fact repository stores objects. Each object includes a collection of facts, where a fact comprises an attribute and a value. An object access module receives objects from the fact repository. The objects can result from multiple different queries executed against the fact repository. A user interface (UI) generation module provides a UI enabling an end-user to designate objects from multiple different queries for subsequent analysis by storing the objects in a virtual collection.

Abstract: Methods and systems for processing facts with one or more janitors. Facts are extracted from documents on the Internet or other sources. Facts can be any data or series of data in the documents including an attribute and a file. The data can be in the form of text, graphics, or multimedia content. Janitors transform facts responsive to inferring a certain condition associated with facts. The condition can be related to one or more of an attribute, a value, or an object of a fact being analyzed. For example, janitors can perform normalization, remove or merge similar or duplicate facts, segregate multiple values of a fact, and the like. An administrator can select which janitors are applied to facts and in which order.

Abstract: A method and a system for providing snippets of source documents of an answer to a fact query are disclosed. Snippets of source documents may be provided in response to a user request for the source documents from which the fact answer to a fact query was extracted. The snippets include the terms of the fact query and terms of the answer. The snippets may be displayed along with Uniform Resource Locators (URL's) of the source documents.
