An Approach to Proper Name Tagging for German
This paper presents an incremental method for the tagging of proper names in
German newspaper texts. The tagging is performed by the analysis of the
syntactic and textual contexts of proper names together with a morphological
analysis. The proper names selected by this process supply new contexts which
can be used for finding new proper names, and so on. This procedure was applied
to a small German corpus (50,000 words) and correctly disambiguated 65% of the
capitalized words, which should improve when it is applied to a very large
corpus.Comment: 6 pages, LaTeX, 2 uuencoded tar-compressed eps-figures added,

A Newbie at the RDAP Summit, or How I Learned that the RDAP Summit is for Everyone
This commentary describes the thoughts and perceptions of a first-time attendee to the Research Data Access and Preservation (RDAP) Summit in March 2018. The author describes her initial hesitations to attend this conference as a data librarian from a medium-sized institution. But after attending, she is convinced that the RDAP Summit is for anyone interested in data, including librarians that work at medium- and small-sized institutions.
After describing the format of the Summit, the highlights of attending are described, including gathering ideas related to all aspects of research data management, access, and preservation; hearing data management perspectives from outside of academic libraries; networking opportunities for the extrovert and introvert; and opportunities to connect with librarians at similar universities and with similar interests
Local Resources for Parents and Youth with Disabilities
The Coalition and the Maine Developmental Disabilities Council sought to revise and update its diagram for supports across the lifespan so it can be presented in an easy to read, user friendly manner. As a LEND trainee, I revised its materials related to the Developmental Services Lifelong continuum of Care and the Blueprint for Effective Transition.https://digitalcommons.library.umaine.edu/ccids_posters/1042/thumbnail.jp
Development and Benchmarking of Novel Electronic Structure Methods based on the Algebraic Diagrammatic Construction and Unitary Coupled Cluster Schemes
During the last three decades, the field of theoretical and computational chemistry has
evolved rapidly, promoted by the increasing availability of computational power inherent in
modern CPUs and cluster structures. This development has expressed itself in a particular
manner in the formulation of modern state-of-the-art electronic structure methods in the
frameworks of, for instance, the Algebraic Diagrammatic Construction scheme or Coupled
Cluster. Application of these methods to the calculation of molecular excitation energies
and properties that describe the most fundamental processes of light-matter interaction, has
been established as a profound and reliable tool for experimentalists within chemistry and
molecular sciences.
This work, which is spilt into three main parts, presents the implementation as well as
benchmarking of novel electronic structure methods for the Algebraic Diagrammatic
Construction scheme (ADC) as well as Unitary Coupled Cluster (UCC).
In the first part, an implementation and benchmark study for the calculation doubly-ionized
as well as double electronically-attached states for ADC, termed DIP-ADC and DEA-ADC,
respectively, up to third order is presented. The implementation was executed in the
Q-Chem program package, benchmark studies included the comparison of states to Full CI
data for DIP as well as EOMDIP-CCSD and EOMDEA-CCSD. For both schemes, the
third-order methods DIP-ADC(3) as well as DEA-ADC(3) proved to produce results which
are in a remarkable good agreement to the corresponding EOM-CCSD method.
As for the second part, a benchmark study on core excitation energies in the framework of
Unitary Coupled Cluster was presented. To this end, the Core-valence separation
approximation was applied to the second-and third-order UCC schemes for electron
excitations. It was shown that CVS-UCC is very suitable in the computation of X-ray
spectra, similar to CVS-ADC, which has been studied before by Wenzel et al. and that it
provides reliable data for the description and simulation of energetically high-lying core
excitations.
The last part of this work features an implementation of an automated code generator for
Unitary Coupled Cluster as it was realized by Leitner et al. for the computation of
electronically excited states on a ADC(4) level. Working equations for a UCC3-x scheme
(in similarity to UCC2-x with an extended description of the doubles/doubles block of the
secular matrix) as well as a full UCC4 for the calculation of electronically-excited states
and properties are presented, together with an improved ground-state description, termed
UCC4+5[s,t] that includes fifth-order terms.
At the end of this work, all results for the three presented topics are summarized in detail,
accompanied by a short outlook of what could include future work and development
