Vacancy | Intern Data Science

Intern Data Science

32 - 40 hours, Arnhem, Netherlands

At Hammer, we operate on the cutting-edge of consultancy and market research. We help our clients to make informed strategic decisions based on fact-based market intelligence about their markets, customers and competitors. Our clients are start-ups, family businesses and multinationals. As a young organization (<7 years old), we are steadily growing and adding new clients to our portfolio. So, we constantly need bright minds to support us.

Job Description

We have been collaborating with students from the Radboud University to improve the value and efficiency of our internal data platforms. Currently we are working on an information retrieval system called Hammer Goldmine. Goldmine optimizes the workflow of our market intelligence team. The name comes from the analogy that the data warehouse we are building is a goldmine of valuable information.

The goal of Goldmine is to increase effectiveness of information searches and to reduce the amount of time Hammer employees have to search to find the right pieces of information. It achieves this by running a classifier on validated source data to determine the value of pieces of information for different Hammer projects. We have completed a successful proof-of-concept phase and are currently expanding the functionalities of Goldmine. A lot of exciting ideas are waiting to be implemented, potentially by you!

Some examples of internship opportunities at Hammer:

  • Building and training a classifier that automatically tags text snippets based on an active learning pipeline that enables progressive improvement based on continuous expert feedback.
  • Improving the Goldmine topic modelling pipeline and expanding it into new areas like products/goods and geographical topics.
  • Building and maintaining of web scrapers to retrieve news articles and processing data from internal data lakes relevant for our subjects of analysis and clients.

The above list of internship opportunities is not exhaustive. You can always contact us for an introductory meeting to see if we have a project that fits your development track.

What do you bring to the table?

We are looking for a student (either Bachelor, Master or higher professional education) with a technical background to assist us in taking Goldmine to the next level. We are mainly looking at students from a study related to data science, computer science, or artificial intelligence. No specific skill set is required, but some useful skills that are convenient in many of our projects are:

  • Basic programming skills
  • Understanding of machine learning principles
  • Understanding of Natural Language Processing (NLP)
  • Understanding of database management tools (SQL/NoSQL)
