Claim 0:
1. A selection apparatus comprising:
a calculation unit, including one or more processors, configured to:
receive a document that includes a plurality of words;
select compound word candidates as a subset of consecutive words from the plurality of words in the document;
calculate a degree of association between each of the words included in the compound word candidates;

a selection unit, including one or more processors, configured to:
select, as a compound word, a compound word candidate from the compound word candidates based on a corresponding degree of association that satisfies a predetermined threshold value;

a learning unit, including one or more processors, configured to:
generate training data that comprises a positional relationship between the words of the selected compound word in the document and predetermined tags added to the document;
train a machine learning model using the generated training data, wherein the machine learning model is trained to identify portions of other documents to which one or more predetermined tags are to be added; and

an addition unit, including one or more processors, configured to:
input, to the trained machine learning model, test data that comprises a compound word and a position of the word in another document; and
obtain, from the trained machine learning model, data indicative of a predetermined tag and a position to which to add the predetermined tag to the other document.
