An instance selecting apparatus stores a plurality of instances each of which includes an item name and an item value. The item name denotes the name of an item, whereas the item value denotes the value of the item. When having received a meta information that includes an item name and an item value, the instance selecting apparatus calculates, for each of the instances, a relevance degree showing a relationship between the instance and the meta information, by applying a weighting coefficient to a level of similarity between the meta information and at least one of the item name and the item value of the instance. The instance selecting apparatus then selects one or more of the instances having a higher level of relevance with the meta information, based on the relevance degrees.
