Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for scoring candidate answer passages. In one aspect, a method includes receiving a query determined to be a question query that seeks an answer response and data identifying resources determined to be responsive to the query; for a subset of the resources: receiving candidate answer passages; determining, for each candidate answer passage, a query term match score that is a measure of similarity of the query terms to the candidate answer passage; determining, for each candidate answer passage, an answer term match score that is a measure of similarity of answer terms to the candidate answer passage; determining, for each candidate answer passage, a query dependent score based on the query term match score and the answer term match score; and generating an answer score that is a based on the query dependent score.

The present invention is directed to a method and system for correlating time-series data with events derived from text mining. The system is configured to receive a time period and a parameter concerning an entity, retrieve an event which is related to the entity and occurred within the time period from events which are previously extracted automatically from unstructured text, and display an indication of the event superimposed on a display representing the time series of the parameter for the time period.

Displaying time-series data and correlated events derived from text mining

Techniques for automatically focusing searches conducted by a search engine are provided. According to one aspect, revised query terms are automatically generated based on text in links that are in incoming (and/or outgoing) link lists associated with documents that are referenced in initial search results generated based on initial query terms. For example, some of the phrases that appear in incoming (and/or outgoing) links associated with a result document may be selected. The selected phrases may be added to the initial query terms to generate revised query terms. These revised query terms may be submitted automatically to the search engine in order to produce a more focused list of revised search results. This process may be performed repeatedly, each iteration revising query terms generated by the previous iteration, until specified criteria are satisfied, at which point the final revised search results may be presented to a user.

Determining related terms based on link annotations of documents belonging to search result sets

In accordance with one aspect of the present exemplary embodiments, a calibration arrangement is configured to assist in calibration of a surface scanning system where the calibration arrangement includes a preconfigured physical object which may embody dimensional information wherein the dimensional information is used to calibrate a surface of the scanning system. In an alternative embodiment, the preconfigured physical object is configured to obtain data for use in calibration of the surface of a pan/tilt surface scanning system.

A process for generating with unification based grammars such as Lexical Functional Grammars which uses construction and analysis of generation guides to determine internal facts and eliminate incomplete edges prior to constructing a generation chart. The generation guide can then be used in the construction of the generation chart to efficiently generate with unification-based grammars such as Lexical Functional Grammars. The generation guide is an instance of a grammar that has been specialized to the input and only contains those parts of the grammar that are relevant to the input. When the generation guide is analyzed to determine internal facts a smaller generation chart is produced.
