Bennett Kleinberg

I am an Assistant Professor (Lecturer) in Data Science at the Department of Security and Crime Science and the Dawes Centre for Future Crime at University College London. I also hold a guest affiliation at the University of Amsterdam’s Department of Psychology.

My research is about two areas:

(1) Computational approaches to security and crime problems

With more data and a changing landscape of problems, computational techniques are an exciting way to look at existing and novel crime and security problems. I’m especially interested in emerging crime problems and understanding them through complex text data with techniques from natural language processing and applied machine learning.

Ideas I’m working on:

examining new (crime) problems on the Internet through text (e.g., online forums)
hybrid decision-making in uncertain, large-volume environments
keyboard dynamics as a biometric identifier
trajectories of language use

(2) Methods of behavioural data science

Before computational methods can help us understand problems better (or at scale), we need suitable methods and tested assumptions. I’m particularly interested in building robust methods to learn about human behaviour from text and web data. Aside from natural language processing, I’m here also involved in the tool development for computational social science, including applied machine learning.

Ideas I’m working on:

automated, learning-based text anonymisation (SAGE Ocean concept grant winner), (more info)
examining the fundamental assumptions of behavioural data science (e.g. the cognition-language-behaviour nexus)
sample size estimation for machine learning in the social and behavioural sciences
researchers’ degrees of freedom in natural language processing studies

Software

NETANOS - Named entity-based text anonymization for open science
- Anonymises bunches of text files by removing identifiable information
- de-identifies numbers, persons, locations, places, pronouns, dates and times
- Developed with Maximilian Mozes and Bruno Verschuere
- Available on npm, source code on GitHub
- Published paper in JOSS and experimental validation on OSF servers
- Accessible interface version lives on netanos.io
Naive context sentiment analysis
- Performs sentiment analysis that handles valence shifters (e.g., “really”, “not”, “hardly”, “but”) on non-punctuated or poorly punctuated data
- Code lives on GitHub
- Specific use cases:
  - data that are not punctuated at all (e.g., auto-generated YouTube transcripts)
  - data that are badly punctuated (e.g., data from blogs where punctuation is not necessarily a given)
  - very brief text data: Twitter data, for example, even if properly annotated for sentence-boundary-disambiguation, would return one or two sentiment values with other sentiment extraction packages
