Additive stucture, rich lines, and exponential set-expansion
… a partial categorization of bivariate polynomial set functions which induce exponential expansion on all finite sets of real numbers.

Empower entity set expansion via language model probing
Entity set expansion, aiming at expanding a small seed entity set with new entities belonging to the same semantic class, is a critical task that benefits many downstream NLP and IR applications, such as question answering, query understanding, and taxonomy construction. Existing set expansion …

FUSE: Multi-faceted set expansion by coherent clustering of skip-grams
"Set expansion aims to expand a small set of seed entities into a complete set of relevant entities. Most existing approaches assume the input seed set is unambiguous and completely ignore the multi-faceted semantics of seed entities. As a result, given the seed set {""Canon"", ""Sony"", …

Networks, Polarization, and Voting: Models for Information Aggregation in Social Settings
… consequence of information aggregation in social settings. These are both classical topics that have motivated studies from various disciplines, and active areas in need of new models as novel phenomenon, demand, and proposals continue to emerge in recent years. In this thesis, we study three …

Vibrational many-body methods for molecules and extended systems
… and a correlation-consistent basis set series to achieve the complete-correlation, complete-basis-set limits of the potential energy surfaces. The mean absolute deviation between the predicted and the observed frequencies is 11 cm$^{-1}$. For extended systems, we generalized the …

Extension and applications of the GVVPT2 method to the study of transition metals
… research efforts have been devoted, can be set exactly to zero. The present work therefore realized, for the first time, a new DFT-in-DFT embedding theory that neither relies on kinetic functionals nor requires a supermolecular DFT calculation. Test calculations using the new embedding …

Theoretical and Computational Aspects of the Optimized Effective Potential Approach within Density Functional Theory
… to the Kohn–Sham potential that generates the set of orbitals employed in the energy evaluation. The focus on the potential can be problematic in finite basis set approaches as determining the exchange-correlation potential in this manner is an inverse problem which, depending upon the …

Information extraction for clinical narratives
Recent US government initiatives have made available a large number of Electronic Health Records (EHRs). These EHRs contain valuable information which can be used in Clinical Decision Support (CDS). So, Information Extraction (IE) from EHRs is a very promising research area. In this thesis, I focus …
