HAAFOR CHALLENGE 2019
 
This year challenge’s task is Predicting Missing Words in a Sentence. Last year’s topic was NER(Named Entity Recognition). This time you need to predict appropriate words for blanks in news articles. We encourage participants to develop algorithm, which can select the fittest words from a given list of words in order to fill out the blanks.
 
For example:
 
Q: Beyond the obvious clinical and regulatory risks, threats to drug pricing and profitability are the key potential drags on the sector. While it's unlikely that Medicare will come any closer to having [BLANK] power in 2016, there is some potential for headline risk from fresh political saber-rattling to induce weakness beyond what is already included. Consolidation in private payers and Medicare providers is a bigger concern, as the combined entities are likely to have better bargaining power.
 
A: negotiating
 
90,000 short news articles(Training Set) with blanks and correct answers will be provided in the beginning of HAAFOR challenge 2019. On Evaluation Day, we will provide additional 20,000 short news articles(Evaluation Set) without answers. You are supposed to submit the predicted words for Evaluation Set within 3 hours. HAAFOR expect this challenge to become a good opportunity for you to perform your optimal level of ability and potentiality.

HAAFOR Challenge 2018

HAAFOR Challenge is annual event through which we seek to expose participants to various areas such as applied/financial math, computational science, machine-learning and artificial intelligence that we utilize in quantitative trading. This year’s challenge will focus on natural language processing (NLP). NLP is an important research area in HAAFOR as many sources of information relevant to financial predictions exists in unstructured format, e.g news and financial reports. Research and development of NLP techniques allow us to tap into these valuable data and utilize them to generate diversified sources of returns.
 
This year’s challenge task is named entity recognition (NER). While general purpose NER is more or less a solved problem, recognizing company names in financial texts poses higher difficulty, due to heterogeneity in the structure of their names. For example, Apple Inc (Cupertino-based iPhone maker) may show up in many different forms as  ‘Apple’, ‘Apple Computers’, ‘Apple Computer, Inc’, ‘Apple Inc’, ‘Apple (Singapore)’, Apple (Korea). We would like participants to design and implement an algorithm to identify mentions of certain companies in the corpus provided. Along with the corpus, participants will be provided with a mapping of relevant CompanyID, OfficialName in which
 

  • CompanyID is a unique number identifying each company
  • OfficialName is the “official” name of the company as used by stock exchanges and brokerages, e.g. ‘Apple Inc’ 

 
Given the above mapping and the corpus, the algorithm should parse each article and return the CompanyIDs of all relevant companies mentioned in the article. An evaluation corpus containing 100K articles will be provided, for which participants will label using the algorithm they have implemented. Please see attachment for the details. If you would like to participate in HAAFOR Challenge 2018, please send your application form(attached) to hfchallenge@haafor.com
 
Winners will be selected based on the evaluation method above. Selected winners will be awarded with prizes as below.

  • 1st and 2nd winner : Apple iPad Pro, 256GB
  • 3rd to 5th winners : Mechanical Keyboard
  • 5 random participants : High-end Headset  



In addition, winners and top-ranking participants will be invited for job interviews at our Singapore or Korea office.
