A mistake to read item to entity map

[RichardHGL]

When I run the code for jtransup model, I find that logger Find 0 aligned items and entities!

I have check it out, jTransUP.data.load_kg_rating_data import load_data, this function has an error that matters,

def loadR2KgMap(filename):
    i2kg_map = {}
    kg2i_map = {}
    with open(filename, 'r', encoding='utf-8') as fin:
        for line in fin:
            line_split = line.strip().split('\t')
            if len(line_split) != 3 : continue
            i_id = line_split[0]#int(line_split[0])
            kg_uri = line_split[2]
            i2kg_map[i_id] = kg_uri
            kg2i_map[kg_uri] = i_id
    print("successful load {} item and {} entity pairs!".format(len(i2kg_map), len(kg2i_map)))
    return i2kg_map, kg2i_map

It's neccessary to use i_id = line_split[0], or 0 items will be aligned.
Have a look at it!
