A method, a structure, and a computer system for expanding database column names. Exemplary embodiments may include identifying glossary terms that sufficiently syntactically match a column name, extracting partial expansions from the glossary terms, selectively combining a set of the partial expansions, and storing the combined set of partial expansions in association with the column name.

Expanding database column names

Detecting sequences of computer-executed operations, including training a BLSTM to determine forward and backward probabilities of encountering each computer-executed operations within a training set of consecutive computer-executed operations in forward and backward execution directions of the operations, and identifying reference sequences of operations within the training set where for each given one of the sequences the forward probability of encountering a first computer-executed operation in the given sequence is below a predefined lower threshold, the forward probability of encountering a last computer-executed operation in the given sequence is above a predefined upper threshold, the backward probability of encountering the last computer-executed operation in the given sequence is below the predefined lower threshold, and the backward probability of encountering the first computer-executed operation in the given sequence is above the predefined upper threshold, and where the predefined lower threshold is below the predefined upper threshold.
