Historical linguistics
Historical linguistics (also called diachronic linguistics) is the study of language change. It has five main concerns: to describe and account for observed changes in particular languagesto reconstruct the pre-history of languages and determine their relatedness, grouping them into language families (comparative linguistics)to develop general theories about how and why language changesto describe the history of speech communitiesto study the history of words, i.e. etymology. History and development[edit] Modern historical linguistics dates from the late 18th century. It grew out of the earlier discipline of philology, the study of ancient texts and documents dating back to antiquity.

The original PropBank The original PropBank project, funded by ACE, created a corpus of text annotated with information about basic semantic propositions. Predicate-argument relations were added to the syntactic trees of the Penn Treebank. This resource is now available via LDC. PropBank today This project was continued under NSF funding and DARPA GALE and BOLT. with the aim of creating Parallel PropBanks (the English-Chinese Treebank/PropBank) and also PropBanking other genres, such as Broadcast News, Broadcast Conversation, WebText and Discussion Fora, at the University of Colorado. PropBank is also being mapped to VerbNet and FrameNet as part of SemLink: Mapping together PropBank/VerbNet/FrameNet.
NomBank
We began this project firmly on the shoulders of Catherine Macleod's Nomlex project and related work on support verbs. This turned out to be a big boost as about one half of the argument-taking nouns in the corpus are nominalizations or nouns that have nominalization-like properties (e.g., "aggression" and "agenda" have argument structures similar to the verbs "destroy" and "schedule"). NomBank has forced us to define noun argument structure in great detail, including areas that have little if any previous research. So in many ways, we are carving out new ground. Some sample phenomena that we cover include: support verb constructions ("John MADE A DECISION"); arguments across copulas ("His decision WAS TO LEAVE"); and parenthetical PP constructions ("Trading in Cineplex Odeon Corp. shares was halted on the New York and Toronto stock exchanges late yesterday afternoon AT THE COMPANY'S REQUEST").

SALSA Project Home
The aim of SALSA II is to provide a large, frame-based lexicon for German, with rich semantic and syntactic properties, as a resource for linguistic and computational linguistic research, investigate probabilistic and hybrid methods for wide-coverage semantic annotation, and explore the use of frame semantic annotations for dynamic semantic analysis in practical NLP applications, especially information access. For more information, see our overview page. SALSA II is funded by the German Science Foundation DFG and builds on its predecessor project SALSA, in particular the German SALSA/TIGER corpus with manually annotated FrameNet frame structures.
Theoretical linguistics
Theoretical linguistics is the branch of linguistics which inquires into the nature of language itself and seeks to answer fundamental questions as to what language is and why languages have the properties they have. Linguistic metalanguage, theories, methodology, and the construction of analytical models of language are part of theoretical linguistics.[1] Theoretical linguistics is situated between descriptive linguistics and language philosophy. While the basic linguistic terminology is shared by most or all, different approaches to linguistic research have developed their own terminology. Various frameworks of linguistic inquiry may also understand same terms in different ways, depending on which theory of language they support.
