Håkan Burden, GSLT PhD student at CSE, will defend his licentiate thesis "Three Studies on Model Transformations - Parsing, Generation and Ease of Use".

Opponent/discussion leader: Leon Moonen, Simula Research Laboratory, Oslo, Norway

Abstract:

Transformations play an important part in both software development and the automatic processing of natural languages. We present three publications rooted in the multi-disciplinary research of Language Technology and Software Engineering and relate their contribution to the literature on syntactical transformations.

Parsing Linear Context-Free Rewriting Systems
The first publication describes four different parsing algorithms for the mildly context-sensitive grammar formalism Linear Context-Free Rewriting Systems. The algorithms automatically transform a text into a chart. As a result the parse chart contains the (possibly partial) analysis of the text according to a grammar with a lower level of abstraction than the original text. The uni-directional and endogenous transformations are described within the framework of parsing as deduction.

Natural Language Generation from Class Diagrams
Using the framework of Model-Driven Architecture we generate natural language from class diagrams. The transformation is done in two steps. In the first step we transform the class diagram, defined by Executable and Translatable UML, to grammars specified by the Grammatical Framework. The grammars are then used to generate the desired text. Overall, the transformation is uni-directional, automatic and an example of a reverse engineering translation.

Executable and Translatable UML - How Difficult Can it Be?
Within Model-Driven Architecture there has been substantial research on the transformation from Platform-Independent Models (PIM) into Platform-Specifc Models, less so on the transformation from Computationally Independent Models (CIM) into PIMs. This publication reflects on the outcomes of letting novice software developers transform CIMs specified by UML into PIMs defined in Executable and Translatable UML.

Conclusion
The three publications show how model transformations can be used within both Language Technology and Software Engineering to tackle the challenges of natural language processing and software development.

Shafqat Virk (graduate student at Applied IT) will defend his thesis for the licentiate degree: "Computational Grammar Resources for Indo-Iranian Languages"

Discussion leader: Hans Leiß

Abstract:

A lot of research is being carried out on different aspects of natural language processing (NLP). As a result, there exist state of the art machine translation systems such as Google translate. These systems are based on data driven (i.e. statistical) approaches, which provide huge coverage, but at the cost of limited accuracy. On the other hand knowledge intensive (i.e. grammar based) approaches provide high quality translations, but their coverage is limited. Generally speaking, one can say that a combined solution with human-like capabilities for accuracy and coverage is yet too far to be reached. One major reason of this limitation is the fact that natural languages are complex and ambiguous. This makes it a challenging task to develop a computational grammar of a natural language. Developing a grammar of a natural language requires at least comprehensive knowledge of the language, expertise to describe it, and also practical skills with a grammar formalism tool. This thesis is devoted to the development of computational grammars of four Indo-Iranian languages: Nepali, Persian, Punjabi, and Urdu. We explore different lexical and syntactical features of these languages and develop their resource grammars according to the requirements of Grammatical Framework (GF) resource grammar API.

Grammatical Framework (GF) is a grammar formalism tool, which has been used to develop grammars of a number of natural languages. So far most of these languages belong to the Germanic, Romance, or Slavic branches of the Indo- European family of languages. On the other hand, Indo-Iranian is the largest branch of the Indo-European family. With 310 living languages, this branch comprises 70% of the total languages in its family. Most of these Indo-Iranian languages have either very limited computational resources or no resources at all. This is one reason of developing resource grammars of these resource-limited languages.

Furthermore, Indo-Iranian languages have some distinctive features such as the Ezafe construction and the partial ergativigy. Previously, none of these features has been implemented in GF. Another reason of this study is to explore this dimension, and demonstrate implementation of these features in GF

Ramona Enache (graduate student at CSE) will defend her thesis for the licentiate degree: "Automating the development of multilingual grammars"

Opponent: Gordon Pace, University of Malta

Abstract:

The thesis aims at exploring alternative ways of automating the development of multilingual GF (Grammatical Framework) grammars. The goal is to achieve semantics-preserving machine translation within a limited or semi-limited domain.

First, there is an experiment that investigates the relation between language skills, programming skills and the effort to develop a grammar for natural language. Along with this, we present a prototype for an example-based system aimed at automating and simplifying the task of GF grammar writing. This is done by partially alleviating the burden of GF programming and facilitating the integration of SMT (statistical machine translation) tools and feedback from native informants into the development of a GF grammar.

Secondly, there is work on ontology representation in GF. The goal is to automatically build a robust language-independent semantic interlingua for the multilingual grammars, by using the projection of the ontology as a GF grammar. In this way the ontology can be verbalized with little effort into a number of languages. The resulting GF grammar is a controlled language describing ontological concepts and their relations as defined in the initial ontology.

Another approach towards automating and enhancing GF grammars is the grammar-based approach to a rule-based SMT hybrid translation system. In order to increase the coverage of a grammar, we enriched it with a bilingual lexicon built on the fly, with the aid of an SMT system specialised on the corpus. The goal of the hybrid system is to parse English patent claims from the biomedical domain and translate them to French. The work represents the first large-scale experiment to use GF for parsing arbitrary unstructured text.

A final direction considered is the development of a general language resource for Romanian. It can be used to build domain-specific resources which will use it as a library for handling syntactic phenomena. In this way more multilingual GF grammars can be ported to Romanian, without the need to re-implement the linguistic technicalities of the language every time.
