Computational Linguistics
Karine Megerdoomian
The Oxford Handbook of Persian Linguistics. Anousha Sedighi and Pouneh Shabani-Jadidi (eds.). Routledge.
Introduces computational linguistics and NLP, examining their relationship to formal linguistic theory. Reviews Persian language technologies and challenges involving the writing system, word boundaries, compounds, and light verb constructions, and identifies directions for further development.

Recursion and Scaling in Complex Predicates: Light Verbs as Underspecified Regular Verbs
Karine Megerdoomian
Workshop on Complex Predicates in Iranian languages, in conjunction with the Second North American Conference in Iranian Linguistics (NACIL2)
Proposes that Persian light verbs are underspecified regular verbs and that complex predicates reproduce verb phrase structure at a smaller scale. Differences in interpretation emerge from the verb's degree of underspecification and its combination with the nonverbal element.

On the Positional Distribution of an Armenian Auxiliary: Second Position Clisis, Focus and Phases
Arsalan Kahnemuyipour and Karine Megerdoomian
Syntax, Vol. 20, Issue 1, pp 77-97

Coauthorship Networks in Linguistics
Karine Megerdoomian
Presentation for course in Network Analysis, Computational Social Science department, George Mason University
Compares collaboration patterns in theoretical linguistics and NLP using publication data, coauthorship networks, and topic analysis. The study finds a more interconnected NLP network, while the linguistics network contains many isolated authors and smaller collaboration groups, with differences across research areas and institutions.

Multilayer Explorations of Zipf's Law in Linguistic Structure
Karine Megerdoomian
Paper for course in Power Law, Computational Social Science department, George Mason University,
Tests Zipf’s Law across Persian corpora at different levels of linguistic analysis, including word forms, compounds, morphology, and word senses. Finds Zipfian patterns across several word-level representations, but not in the frequency distribution of syntactic categories alone.

Karine Megerdoomian
MITRE. McLean, Virginia
Maps research trends and collaboration networks in ACL and NAACL publications from 2007-2014. Topic and co-authorship analyses examine the prominence of statistical machine translation, emerging semantic approaches, and the concentration and interconnectedness of research activity.

Text Normalization
Karine Megerdoomian
MITRE. McLean, Virginia
Examines how spelling, capitalization, diacritics, and character encoding affect text matching across languages. Illustrates the benefits and limitations of normalization through its application to Arabic sentiment analysis in the Hedonometer project.
