Focus Group: Data Analytics (Prof. Gemulla)

Our group's research focuses on systems and methods for analyzing and mining large datasets as well as their application in practice. Our research interests include:
  • Data analysis and data mining
  • Text mining and information extraction
  • Optimization
  • Approximation techniques
  • Algorithms for modern hardware

Data and Software

  • MinIE: Open information extractor (spiritual successor to ClausIE)
  • DSGDpp: Various parallel algorithms for matrix factorization (including DSGD++)
  • DESQ: Frequent sequence mining with subsequence constraints
  • Rounding rank: algorithms for computing rounding-rank decompositions
  • CORE: Context-aware open relation extraction with factorization machines
  • FINET: Context-aware fine-grained named entity typing
  • Werdy: Recognition and Disambiguation of Verbs and Verb Phrases with Syntactic and Semantic Pruning
  • ClausIE: Clause-Based Open Information Extraction
  • LEMP: Fast Retrieval of Large Entries in a Matrix Product
  • LASH: Large-Scale Sequence Mining with Hierarchies
  • MG-FSM: Large-Scale Frequent Sequence Mining
