It producesstructured data ready for post-processing which is crucial to many applications of web mining andsearching tools. Information extraction systems are software tools which are designed to generatewrappers. A wrapper usually performs a pattern matching procedure which relies on a set of extractionrules. These are classified into four classes which are manually-constructed, supervised, semi-supervisedand unsupervised IE systems. Unsupervised IE systems do not use any labeled training examples andhave no user interactions to generate a wrapper. DEPTA (Data Extraction Based on Partial TreeAlignment) is one of the unsupervised IE system that is designed for record-level extraction task. Theobjective is to segment the data records, extract data items or data fields from them and put them in adatabase table. Depta consists of
