# Semi-Structured

Data of unstructured nature, but still having some high level patterns applicable to it. This semi-structured data has a loosely defined component structure.  We will focus on the Semi-Structured data that are common between verticals. Examples: email, url, address, etc**.**

Telmai can offer: 

Pattern analyzer to identify accepted patterns (only compressed sequence patterns work in these cases and only sometimes) 

Frequency analyzer to identify placeholder or over-represented data 

Regex built-in syntax validators for email, url 

Validation services API or libraries for email, url (see appendix below) 

Validation and normalization of Address via external API calls (see appendix below)
