Introduction

The FinSim-3 shared task aims to spark interest from communities in NLP, ML/AI, Knowledge Engineering and Financial document processing. Going beyond the mere representation of words is a key step to industrial applications that make use of Natural Language Processing (NLP). This is typically addressed using either 1) Unsupervised corpus-derived representations like word embeddings, which are typically opaque to human understanding but very useful in NLP applications or 2) Manually tagged resources such as corpora, lexica, taxonomies and ontologies, which typically have low coverage and contain inconsistencies, but provide a deeper understanding of the target domain.

These two methods form the two ends of a spectrum which a number of approaches have attempted to combine, particularly in tasks aiming at expanding the coverage of manual resources using automatic methods.

• The Semeval community has organized several evaluation campaigns to stimulate the development of methods which extract semantic/lexical relations between concepts/words (Bordea et al. 2015, Bordea et al. 2016, Jurgens et al. 2016, Camacho-Collados et al. 2018).

• There are also a large number of datasets and challenges that specifically look at how to automatically populate knowledge bases such as DBpedia or Wikidata (e.g. KBP challenges).

To the best of our knowledge, FinSim 2020 was the first time a task attempting to combine these methods for the Financial domain.

Task Description

The 3rd edition of FinSim-3 focuses on the evaluation of semantic representations by assessing the quality of the automatic classification of a given list of carefully selected terms from the Financial domain against a domain ontology. Participants will be given a list of carefully selected terms from the Financial domain such as “European depositary receipt”, “Interest rate swaps” and will be asked to design a system which can automatically classify them into the most relevant hypernym (or top-level) concept in an external ontology. For example, given the set of concepts “Bonds”, “Unclassified”, “Share”, “Loan”, the most relevant hypernym of “European depositary receipt” is “Share”.

In this new edition, we propose an extended dataset with more diversified financial concepts. We are interested in systems which make creative use of relevant resources such as ontologies and lexica, as well as systems which make use of contextual word embeddings such as BERT (Devlin et al. 2018).

Participating systems are expected to provide for each given term the most relevant concept (hypernym/synonym) in an external ontology: the Financial Industry Business Ontology (FIBO). Performance will be measured according to the accuracy with which financial terms are classified, and according to recall (based on the total number of predictions).

This task is open to everyone. The only exception are the co-chairs of the organizing team, who cannot submit a system, and who will serve as an authority to resolve any disputes concerning ethical issues or completeness of system descriptions.
