Abstract
A data extraction apparatus includes a parameter analysis unit that performs analysis of learning text information, extracts words that serve as machine learning parameters, and classifies the words into types of parameters; a grouping settings display unit that finalizes search-target data and clustering conditions based on the parameters; at least one clustering training data extraction unit that extracts training data from a database based on the search-target data and the clustering conditions; at least one clustering unit that performs clustering based on the clustering condition on the training data; an applicable-clustering determination unit that performs analysis of search text information and identifies search-target data serving as a narrowing-down condition and which clustering unit is to be operated; and a search range specification unit that causes the clustering unit to operate and extracts a narrowed range of search-target data from the database based on an operation result.
