  • Understanding Email Traffic: Social Network Analysis Meets Language Modeling

    In our paper “Recipient recommendation in enterprises using communication graphs and email content“ we study email traffic, by looking into recipient recommendation, or: given an email without recipients, can we predict to whom it should be sent? Successfully predicting this helps in understanding the underlying mechanics and structure of an email network. To model this prediction task we consider the…

    Information Retrieval at LegalTech 2014

    Thanks to the kind lady at the registration desk I had the unexpected honor of representing the beautiful former Carribean country of the Netherlands Antilles at LegalTech 2014, the self-proclaimed largest and most important legal technology event of the year. LegalTech is an “industry conference” where attorneys, lawyers, and IT people meet up and discuss the current and future…

  • How many things took place between 1900 and today? DBPedia knows

    For a top-secret project, I am looking at retrieving all entities that represent a ‘(historic) event’, from DBPedia. Now I could rant about how horrible it is to actually formulate a ‘simple’ query like this, using the structured anarchistic Linked Data format, so I will: this request “give me all entities that represent ‘events’ from…

  • We won the WoLE2013 Challenge

    With our SemanticTED demo, we (Daan Odijk, Edgar Meij, Tom Kenter and me) won the Web of Linked Entities 2013 Workshop’s “Doing Good by Linking Entities” Developers Challenge (at WWW2013). Read the paper of our submission here: D. Odijk, E. Meij, D. Graus, and T. Kenter, “Multilingual semantic linking for video streams: making “ideas worth sharing” more…

  • Context-based Entity Linking

    The goal of this post is to make the research I’m doing understandable to the general public. You know, to explain what I’m doing in a way not my peers, but my parents would understand. In part because the majority of the returning visitors of my blog are composed of my parents, in part because…

  • Entity Linking – From Words to Concepts

    The last couple of weeks I’ve been diving into the task of entity linking, in the context of a submission to the Text Analysis Conference Knowledge Base Population track (that’s quite a mouthful – TAC KBP from now on). A ‘contest’ in Knowledge Base Population with a standardized task, dataset and evaluation. Before I’m devoting my…

  • Researchblog – First post

    As I’ve finished my MSc thesis and have started working at the Information and Language Processing Systems group (ILPS) at the Universiteit van Amsterdam as a PhD candidate in a project in Semantic Search for e-Discovery, I figured it’d be time to leave my thesis blog behind, and start a brand new research blog.
