-----FILE STRUCTURE-----

The LLL training data format is represented as follows. The files consists of the following fields (one field by line):

  - ID: unique identifier of the Pubmed abstract that contains
    the sentence and the sentence position number
  - sentence: the original sentence
  - words: list of the sentence words
  - agents: list of the agents of the genic interactions
  - targets: list of the targets of the genic interactions
  - genic_interactions:list of the interactions (couples of agent-target) described in the sentence.

-----FIELD STRUCTURE-----

A tab separates each element of a field:

  ID
The ID field contains the abstract PubMed ID (PMID) which the sentence is
extracted from and it contains the sentence position number in this abstract.

ID (tabulation) 11011148-1

  SENTENCE
This field contains the sentence.

sentence (tabulation) ykuD was transcribed by SigK RNA polymerase from
T4 of sporulation.

  WORDS, AGENTS, TARGETS, GENIC_INTERACTIONS
Other fields are organised according to the following format :

Field_Name (tabulation) predicate1(argument1_1,argument1_2,...)
(tabulation) predicate2(argument2_1,argument2_2,...) (tabulation)...

-----PREDICATE DESCRIPTION-----

  WORD
The predicate "word" refers to a word of the sentence and accepts four
arguments:

word(id_word,'string_word',start_word,end_word)

id_word: integer, unique word id
string_word: string, the actual word
start_word: integer, position of the first character in the sentence
(starting at 0)
end_word:integer, position of the last character in the sentence
(starting at 0)

  AGENT
The predicate "agent" refers to the agent of the genic interaction. It
accepts one argument:

agent(id_word)

id_word: integer, id of the word the agent refers to

  TARGET
The predicate "target" refers to the target of the genic interaction. It
accepts one argument:

target(id_word)

id_word: integer, id of the word the target refers to

  GENIC_INTERACTION 
The predicate "genic_interaction" refers to an
interaction between an agent and a target:

genic_interaction(id_word1,id_word2)

id_word1: integer, id of the word the agent refers to
id_word2: integer, id of the word the target refers to
