An apparatus to support creation and management of metadata for correcting a problem in a dynamic web application. The support apparatus includes a metadata creation section, a block extraction section, a similar-block search section, and a metadata generalizing section. In response to correction of a problem by a corrector, the support apparatus creates metadata including the details of the correction and application conditions, that is, a global variable group and cookie information that identify the state of the web application in which the problem has occurred, extracts another block to which the created metadata is applicable from an operation log by using a semantic block including the location of the problem as a clue, and generalizes the application conditions of the created metadata by converting them to a key-value pair structure by using the other block and by extracting a common portion therefrom.
