Broaden legislative acts extraction

[spapadiamantis]

The codifier module currently detects, codifies and stores all laws and presidential decrees that are found in the Greek Government Gazette issues.Even though these types of amendments are most important in Greek legislation they do not account for the largest part of GGG issues.

We want to broaden extraction capabilities using regular expressions to include parliamentary regulations (Κανονισμός της Βουλής), treaties (Συνθήκες), Prime Minister, Minister and Deputy Minister decisions, as well as acts of appointment, dismissal and transfer of public officials. An extensive account of types of legislative acts per GGG issue can be found in the [Ethnikon Typografeion website] (http://www.et.gr/index.php/f-e-k/teyxi).

As mentioned the legislative act extraction is currently performed using regular expressions in the entities module. An alternative to this is would be to train a neural network that can detect legislative acts and determines the type although this would be a complex solution depending on the number of issue types.

Since the GGG corpus contains a great number of types of legislative we should prioritize those found in main issue types such as 'Α', 'Β', 'Γ' , 'Δ'.
