In a turbine vane repairing method, a damaged spot removing step of removing a damaged spot in one shroud of two shrouds, a member disposing step of disposing a deformation curbing member which comes into contact with each of the two shrouds and curbs change in relative positions between the two shrouds, an overlay welding step of performing overlay welding with respect to a removed part from which the damaged spot is removed in the one shroud and filling the removed part after the damaged spot removing step and the member disposing step, a member detaching step of detaching the deformation curbing member from the turbine vane after the overlay welding step, and a finishing step of polishing at least a surface of a part subjected to the overlay welding in the one shroud are executed.

A parameter learning apparatusextracts one entity in a document and a related text representation as a one-term document fact, outputs a one-term partial predicate fact including only the one entity using a predicate fact that includes entities and a predicate, calculates a first one-term score indicating the degree of establishment of the one-term document fact using a one-term partial predicate feature vector, a one-term text representation feature vector, and a one-term entity feature vector that are calculated from parameters, calculates a second one-term score with respect to a combination of one entity and a predicate or a text representation that is not extracted as the one-term partial predicate fact, updates the parameters such that the first one-term score is higher than the second one-term score, and calculates a score indicating the degree of establishment of the predicate fact and a score indicating the degree of establishment of a combination of entities and a predicate that is not obtained as the predicate fact using these scores.

An operation rule determination device includes an environment execution unit that obtains a state of a control target after each operation and the degree associated with the state for a series of operations on the control target, by using degree information in which the state and the degree of desirability of the state are associated with each other, and a risk-considered history generation unit that calculates a cumulative degree obtained by accumulating the obtained degree for the series of operations, and, when the cumulative degree satisfies a condition, reduces the degree associated with the state after the series of operations in the degree information.

A policy creation unit creates a plurality of policies each including a predetermined number of rules in which a condition for determining a state of an object is combined with an action in the state. An action determination unit determines, for each of the plurality of created policies, an action to be performed while a state of the object is changed from a first state to a second state in accordance with the policy. A policy evaluation unit determines, in accordance with a difference between a state between the first state and the second state and a desired state, the quality of the determined action and determines, for each of the plurality of policies, the quality of the policy based on the determined quality of the action. A policy selection unit selects the policy that is determined to have a high quality.

An entity combination and a text representation are obtained as a first fact, and the entity combination and a related predicate are obtained as a second fact. Word distributed representations are input to a neural network, real vectors at appearance positions of entities are specified and used as distributed representations. A first score indicating a degree of establishment of the first fact is calculated based on the distributed representations and on entity distributed representations. A second score indicating a degree of establishment is calculated with respect to an entity combination and a text representation that are not the first fact. A third score indicating a degree of establishment of the second fact is calculated based on predicate distributed representations and on entity distributed representations. A fourth score indicating a degree of establishment is calculated also with respect to an entity combination and a predicate that are not the second fact. The entity distributed representations, the predicate distributed representations, or weight parameters are updated by a gradient method, so that the first score becomes higher than one of the second score and the fourth score, and the third score becomes higher than one of the second score and the fourth score.

An adapter device includes a device information manager to manage device information with respect to an electrical device, and a service provider to manage service information and provide the service based on service information. The service information indicates content of the service and includes action information indicating an operation of an electrical device and event information indicating a condition for executing the operation indicated by the action information. An adapter device includes a controller to control the operation of the electrical device. Upon determining that the device information with respect to the electrical device satisfies the condition indicated by the event information, the service provider causes the controller to control the electrical device to perform the operation indicated by the action information.

A dialog apparatusis an apparatus for responding to a dialog act of a user. The dialog apparatusis provided with: a policy unitconfigured to set a score to each of response candidates included in a set of response candidates based on the state of a dialog being performed with the user and a policy parameter, and referring to the set scores, to select one of the response candidates as a dialog act of the dialog apparatus; and a policy parameter updating unitconfigured to obtain a reward in the state of the dialog using a reward function that, as the reward, returns an evaluation of a behavior performed in a specific circumstance as a quantitatively represented numeric value, and to update the policy parameter based on the obtained reward.

An information processing apparatus is disclosed which determines, based on fitness to a specified condition, an order of displaying multiple to-be-searched information items which are pre-stored. The apparatus includes a specifying-condition information obtaining unit, an index-information obtaining unit, a population-limiting information obtaining unit, an index-information modifying unit, and a fitness calculating unit.

An information processing apparatus for creating a retrieval result displaying a list of retrieval documents. Retrieval documents corresponding to a retrieval condition are classified into groups based on scores indicating degrees of relevance to the retrieval condition. A clustering process is conducted with respect to the retrieval documents in a group, for each of groups to which the retrieval documents belong.

An apparatus and method of searching an electronic document are disclosed. A document that is assumed to contain a search symbol set is searched. The search symbol set is a symbol set being extracted from a plurality of symbols representing a search request when the symbol set being extracted satisfies a predetermined condition.

Apparatus and method of searching document data

When a number of document data registered in one of full-text index-for-registration/deletion storage parts reaches a predetermined number, or when a capacity of the full-text index-for-registration/deletion storage part reaches a predetermined capacity, a merge processing is performed for merging data from the full-text index-for-registration/deletion storage part to a full-text index-for-search storage part. While this merge processing is performed, a registration/deletion processing is performed by using another full-text index-for-registration/deletion storage part.
