Common or not common?

This functions returns the possible type for a particular tweet in the case there are common nodes or not.

The function takes as input the results that are the list (possibly empty) of common nodes retured from the commonNodes function and the list of the nodes for each entity in that tweet.

This function returns the set of tags that better describes the tweet, considering the two cases:

1. There are common nodes of the lineages of the mentions.
2. There are not common nodes.

In the first case we consider all the types of the common nodes once and we return them, avoiding the “Thing”-type. In the second case we just pick the first node of the lineage, with higher score and we return the types of that node.

def tweetTag(results,listOfEntites):
#I have two possible cases:
    #result is not empty
    if len(results) != 0:
        tags = set()
        for elem in results:
            for tag in elem.get('types'):
                tags.add(tag)

        tags.remove("Thing")
        return tags

    #result is empty so there are no nodes in common
    else:
        tags = set()
        for list in listOfEntites:
            if list:
                for tag in list[0].get('types'):
                    tags.add(tag)

        tags.remove("Thing")
        return tags
