Malayalam treebank data is in Shakti Standard Format (SSF). SSF is a common representation for data. SSF allows information in a sentence to be represented in the form of one or more trees together with a set of attribute-value pairs with nodes of the trees. The attribute-value pairs allow features or properties to be specified with every node. Sentence level SSF is used to store the analysis of a sentence. It occurs as part of text level SSF. The analysis of a sentence may mark any or all of the following kinds of information as appropriate: part of speech of the words in the sentence; morphological analysis of the words including properties such as root, gender, number, person, tense, aspect, modality; phrase-structure or dependency structure of the sentence; and properties of units such as chunks, phrases, local word groups, tags, etc. SSF is theory neutral and allows both phrase structure as well as dependency structure to be coded, and even mixed in well defined ways. The SSF representation for a sentence consists of a sequence of trees. Each tree is made up of one or more related nodes.
