Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating rendering data that when rendered on a display device presents a graphical user interface that displays a first visual representation of a value curve, a time period selection window that is configured to move along the first visual representation of the value curve to select one or more portions of the first visual representation of the value curve, a second visual representation of the value curve that is based on the selected one or more portions of the first visual representation of the value curve, a first events bar that includes two or more first event icons that are each associated with a different type of event, and a second events bar that includes two or more second event icons that are each associated with a same type of event.

Abstract: A method of information retrieval is provided. The method comprises receiving a query from a user and parsing the query in real-time as the user enters the query. The parsed query is interpreted dynamically based on a defined schema of a knowledge base, and a number of query interpretations is displayed in real-time as the user enters the query. When a selection of one of the query interpretations is received from the user information is retrieved from the knowledge base according to the selected query interpretation.

Abstract: Methods, and systems for a natural language interface with real-time feedback. One of the methods includes receiving an n-gram of characters; identifying a first prefix token within the n-gram of characters; identifying a plurality of possible interpretations of the n-gram of characters; for each possible interpretation, attaching the first prefix token to a token sequence; removing the first prefix token from the n-gram of characters to produce an n-gram remainder; identifying a second prefix token within the n-gram remainder using a tokenizer; identifying a plurality of remaining possible interpretations based on the first prefix token and the second prefix token; for each remaining possible interpretation attaching the second prefix token to a token sequence; applying grammatical rules to each token sequence to determine that each token sequence is valid; and forwarding interpretation data associated with at least one valid token sequence.

Abstract: Methods, systems, apparatus, including computer programs encoded on computer storage medium, for generating rendering data. The method includes actions of receiving a stream of real-time data, analyzing the stream of real-time data to detect a set of one or more attributes associated with a real-time event, identifying, based on the one or more attributes, one or more data records representing an event-outcome pair, wherein an outcome in the event-outcome pair includes data identifying a content item, obtaining historical data associated with the content item, and generating rendering data including data for rendering a first layer representing real-time data specifying a current value of the content item as an overlay to a second layer representing the obtained historical data associated with the content item, with each of the rendered layers being juxtaposed to one or more specified portions of the graphical user interface.
