Determining metadata of a dataset

A computer program product comprising a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code configured to implement a method for enabling a processing of a dataset of records having a set of attributes, the method comprising:

• selecting a first attribute of the set of attributes and a subset of one or more second attributes of the set of attributes;
• determining from the dataset distinct values of the subset of second attributes;
• for each distinct value of the determined distinct values:
• identifying records of the dataset that have said each distinct value, and forming a group of words from values of the first attribute of the identified records;
• identifying distinct word sequences in the formed groups, each word sequence comprising one or more words, and determining a level of presence of each word sequence of the word sequences in each of the formed groups;
• and
• storing at least part of the levels of presence.
