  Retail item data contains many different forms of text like the title of an
item, the description of an item, item name and reviews. It is of interest to
identify the item name in the other forms of text using a named entity tagger.
However, the title of an item and its description are syntactically different
(but semantically similar) in that the title is not necessarily a well formed
sentence while the description is made up of well formed sentences. In this
work, we use a triplet loss to contrast the embeddings of the item title with
the description to establish a proof of concept. We find that using the triplet
loss in a multi-task NER algorithm improves both the precision and recall by a
small percentage. While the improvement is small, we think it is a step in the
right direction of using various forms of text in a multi-task algorithm. In
addition to precision and recall, the multi task triplet loss method is also
found to significantly improve the exact match accuracy i.e. the accuracy of
tagging the entire set of tokens in the text with correct tags.
