A mission for grammar writing : early approaches to Inuit (Eskimo) languages
(2007)
-
Elke Nowak
- The Inuit inhabit a vast area of--from a European point of view--most inhospitable land, stretching from the northeastern tip of Asia to the east coast of Greenland. Inuit peoples have never been numerous, their settlements being scattered over enormous distances. But nevertheless, from an ethnological point of view, all Inuit peoples shared a distinct culture, featuring sea mammal and caribou hunting, sophisticated survival skills, technical and social devices, including the sharing of essential goods and strategies for minimizing and controlling aggression.

A Testsuite for Testing Parser Performance onComplex German Grammatical Constructions
(2009)

- Traditionally, parsers are evaluated against gold standard test data. This can cause problems if there is a mismatch between the data structures and representations used by the parser and the gold standard. A particular case in point is German, for which two treebanks (TiGer and TüBa-D/Z) are available with highly different annotation schemes for the acquisition of (e.g.) PCFG parsers. The differences between the TiGer and TüBa-D/Z annotation schemes make fair and unbiased parser evaluation difficult [7, 9, 12]. The resource (TEPACOC) presented in this paper takes a different approach to parser evaluation: instead of providing evaluation data in a single annotation scheme, TEPACOC uses comparable sentences and their annotations for 5 selected key grammatical phenomena (with 20 sentences each per phenomena) from both TiGer and TüBa-D/Z resources. This provides a 2 times 100 sentence comparable testsuite which allows us to evaluate TiGer-trained parsers against the TiGer part of TEPACOC, and TüBa-D/Z-trained parsers against the TüBa-D/Z part of TEPACOC for key phenomena, instead of comparing them against a single (and potentially biased) gold standard. To overcome the problem of inconsistency in human evaluation and to bridge the gap between the two different annotation schemes, we provide an extensive error classification, which enables us to compare parser output across the two different treebanks. In the remaining part of the paper we present the testsuite and describe the grammatical phenomena covered in the data. We discuss the different annotation strategies used in the two treebanks to encode these phenomena and present our error classification of potential parser errors.

An outline of Proto-Indo-European
(2010)
-
Frederik H. H. Kortlandt
- Indo-European is a branch of Indo-Uralic which was radically transformed under the influence of a North Caucasian substratum when its speakers moved from the area north of the Caspian Sea to the area north of the Black Sea (cf. Kortlandt 2007b). As a result, Indo-European developed a minimal vowel system combined with a very large consonant inventory including glottalized stops, also grammatical gender and adjectival agreement, an ergative construction which was lost again but has left its traces in the grammatical system, especially in the nominal inflection, a construction with a dative subject which was partly preserved in the historical languages and is reflected in the verbal morphology and syntax, where it gave rise to new categories, and a heterogeneous lexicon. The Indo-Uralic elements of Indo-European include pronouns, case endings, verbal endings, participles and derivational suffixes. In the following I shall give an overview of the grammar of Proto-Indo-European as it may have been spoken around 4000 BC in the eastern Ukraine, shortly after the ancestors of the Anatolians left for the Balkans (for more recent developments I refer to Beekes 1995).

Comparing lexicalized grammar formalisms in an empirically adequate way : the notion of generative attachment capacity
(2006)
-
Laura Kallmeyer
- The work presented here addresses the question of how to determine whether a grammar formalism is powerful enough to describe natural languages. The expressive power of a formalism can be characterized in terms of i) the string languages it generates (weak generative capacity (WGC)) or ii) the tree languages it generates (strong generative capacity (SGC)). The notion of WGC is not enough to determine whether a formalism is adequate for natural languages. We argue that even SGC is problematic since the sets of trees a grammar formalism for natural languages should be able to generate is difficult to determine. The concrete syntactic structures assumed for natural languages depend very much on theoretical stipulations and empirical evidence for syntactic structures is rather hard to obtain. Therefore, for lexicalized formalisms, we propose to consider the ability to generate certain strings together with specific predicate argument dependencies as a criterion for adequacy for natural languages.

Focal aspects in the Lelemi verb system
(2006)
-

- In our presentation we will outline the verb system of Lelemi and concentrate on certain “focal” aspects which are of primary interest to us. Lelemi has two TAMP paradigms: one constituting the so-called “simple tenses”, the other the so-called “relative tenses” (Allan 1973), although not every “simple tense” has a counterpart in the “relative tenses”. The simple paradigm is formed by subject prefixes (prefixed pronouns for 1st or 2nd person and noun class pronouns for 3rd persons) and the verb form whereas the relative paradigm is build up by the obligatory use of an external subject noun, an invariable verb prefix, and the verb form. While the simple paradigm is used in quite a lot of syntactic environments the relative paradigm only shows up in relative clauses with the subject being the head as well as in subject and sentence focus constructions including questions concerning the subject. We will show some interesting interactions between the grammatical expression of focus and the verb system and sketch the grammaticalisation path of the morpheme nà.

Focus expressions in Yom
(2006)
-
Ines Fiedler
- This paper deals with the means for expressing the pragmatic category of focus in Yom, which is an Oti-Volta language of the Yom-Nawdem group spoken by about 74,000 people (Gordon 2005, online version) in the department of Donga in Northern Benin. The study is based on results of my field research carried out in March/April 2005 in Djougou (Benin), within the framework of the project “Focus in Gur and Kwa languages”. Main aim of this fieldwork was to study the expression of focus in Yom. Regarding the basic grammatical structure of the language, I mainly rely on various publications by Beacham (1969, 1991, and 1997).
