User information inferring system
First Claim
1. A user information inferring system comprising:
- inferring means for inferring user information, which is information relating to a user, as item values in at least one data set by categorically defining the user information as at least one data set and expressing the data set with items written in data lists corresponding to the data set, wherein at least a part of the item values in each data set changes in conjunction with temporal-spatial elements; and
calculating means for calculating at least one of a temporal characteristics that a temporal element imparts to the item value and a spatial characteristics that a spatial element imparts to the item value, wherein the inferring means infers the item value based on the characteristics calculated by the characteristics calculating means.

Abstract
A user information inferring system defines user information according to five categories, that is, user environment, circumstance, condition, request, and action, and further defines a sixth category, that is, situation data encompassing these other five categories. User information in each of the defined categories, that is, environment, circumstance, condition, request, action, and situation, is then described using item values, and operating units infer the item values. The inference operation uses temporal-spatial characteristics indicative of the effect of temporal-spatial elements on the item values, information about inferred situations, a rule database containing rules describing the relationships between items, and an optimization process for the defined categories using vector expressions.

16. A user information inferring system comprising:
-
inferring means for inferring user information, which is information relating to a user, as an item value in at least one of data set by categorically defining the user information as at least one of data set and expressing the data set with an item written in a data list corresponding to the data set; and
a rule database storing rules correlating items written in the data list for the data set, wherein the inferring means infers the item value based on the rules recorded in the rule database.

28. A user information inferring system comprising:
-
inferring means for inferring user information, which is information relating to a user, as an item value in at least one data set by categorically defining the user information as at least one data set and expressing the data set with an item written in a data list corresponding to the data set, wherein the data set is expressed by a data vector for each data set using the item value as a component; and
distance calculating means for calculating a distance between the data vector and a reference vector indicating an optimum condition for the data set, wherein the inferring means infers the item value to optimize the data set based on the distance calculated by the distance calculating means.

37. A user information inferring system comprising:
-
inferring means for inferring user information, which is information relating to a user, as an item value in at least one data set by categorically defining the user information as at least one data set and expressing the data set with an item written in a data list corresponding to the data set, wherein each data set includes a situation data set indicating a user situation, and wherein the inferring means infers an item value of the situation data set based on item values of other data sets.
