Building apps from big data

Web crawls, Twitter streams, blogs, click logs, ontologies - big data is omnipresent, some of it still kept under lock, but an increasing amount publically accessible. We have the technology to deal with it, structured or unstructred, in streams or in large batches: Hadoop, NoSQL, Storm, S4, and other fun tools. But once you have your tools and you get your data - what can you do?

This meetup will give examples of tools that have been and are still being build around large datasets at universities in The Netherlands. Manos (UvA) and Carsten (TUD) are data scientists who will tell you about tools they've built in the course of their research.

Special guest: Lisa Green, director of Common Crawl

Lisa Green is the Director of the Common Crawl Foundation where she oversees the foundation’s mission of building, maintaining and openly disseminating a comprehensive crawl of the web. Common Crawl’s 130TB corpus of over 8 billion web pages enables innovation in education, research, and business. Prior to Common Crawl, she was the Chief of Staff at Creative Commons. Lisa holds a PhD in physical chemistry from the University of California Berkeley, lives in San Francisco, and is passionate about open systems and big data.

Lisa is in The Netherlands to discuss Common Crawl data with Sara and researchers in The Netherlands. She will also give a colloqium talk on open data on Oct 4th, at 3.30pm, and join us for the HUG.

Talk 1: What you can do with user comments - Carsten Eickhoff (researcher at TUD)

Carsten Eickhoff is a PhD student at Delft University of Technology. His research interests include information retrieval, statistical NLP and crowdsourcing. In particular, his thesis work has been focused on user-centric retrieval scenarios.

In his talk, Carsten will address the usefulness of user comments for retrieval tasks such as (1) automatically identifying child-friendly videos on the popular content sharing platform YouTube, (2) mitigating performance losses for sparsely-annotated data, or, (3) enhancing blog post retrieval.

Talk 2: Social media based apps - Manos Tsagkias (@samanos, researcher at UvA)

Manos Tsagkias has just submitted his PhD thesis on mining social media. His research focuses on tracking content in social media, and predicting behavior using signals from different information channels. In this talk, Manos will demonstrate the power of social media using three use cases: forecast the mood of the blogosphere, predict the number of comments on news articles, and predict IMDb movie ratings using signals from Twitter and YouTube.

    First of alls it was a lot of Fun tpo attend the meeting.
    For me the case studies help me to develop ideas of Hadoop implementation.
    Could have more talk about tech stuff

    Talks were good! Was hoping on a bit more on experiences with hadoop though?

    Vraag: gaat dit event vooral over analyse met Hadoop etc., of vooral over de presentatie van de analyseresultaten op mobiele devices met apps?

      Hoi Reijer! Het gaat eigenlijk weer over data science - wat voor nieuwe dingen kan je maken als je veel data analyseert, en hoe doe je dat dan? De technologie staat niet perse centraal. Ik weet dat Carsten een Hadoop gebruiker is, en dat Manos in een groep zit waar Hadoop veel gebruikt wordt, maar in hoeverre Hadoop zelf een rol heeft gespeeld in het werk dat ze presenteren, dat weet ik niet.
