In this paper, we have addressed the task of PropBank annotation of light verb constructions, which like multi-word expressions pose special problems. To arrive at a solution, we have evaluated 3 different possible methods of annotation. The final method involves three passes: (1) manual identification of a light verb construction, (2) annotation based on(More)
This paper, submitted as an entry for the NERSSEAL-2008 shared task, describes a system build for Named Entity Recognition for South and South East Asian Languages. Our paper combines machine learning techniques with language specific heuristics to model the problem of NER for Indian languages. The system has been tested on five languages: Telugu, Hindi,(More)
The paper describes an annotation scheme for English based on Panini’s concept of karakas. We describe how the scheme handles certain constructions in English. By extending the karaka scheme for a fixed word order language, we hope to bring out its advantages as a concept that incorporates some ‘local semantics’. Our comparison with PTB-II and PropBank(More)
This paper examines both linguistic behavior and practical implications of empty argument insertion in the Hindi PropBank. The Hindi PropBank is annotated on the Hindi Dependency Treebank, which contains some empty categories but rarely the empty arguments of verbs. In this paper, we analyze four kinds of empty arguments, *PRO*, *REL*, *GAP*, *pro*, and(More)
This paper makes two contributions. First, we describe the Hindi Proposition Bank that contains annotations of predicate argument structures of verb predicates. Unlike PropBanks in most other languages, the Hind PropBank is annotated on top of dependency structure, the Hindi Dependency Treebank. We explore the similarities between dependency and predicate(More)
We are in the process of creating a multi-representational and multi-layered treebank for Hindi/Urdu (Palmer et al., 2009), which has three main layers: dependency structure, predicate-argument structure (PropBank), and phrase structure. This paper discusses an important issue in treebank design which is often neglected: the use of empty categories (ECs).(More)
The linguistic annotation of noun-verb complex predicates (also termed as light verb constructions) is challenging as these predicates are highly productive in Hindi. For semantic role labelling, each argument of the noun-verb complex predicate must be given a role label. For complex predicates, frame files need to be created specifying the role labels for(More)
Almost all transactions ranging from various domains such as travel, shopping, insurance, entertainment, hotels, appointments etc. are available through Internet based applications. Needless to say, all these applications require the knowledge of English. As Internet users are growing day by day, it is logical to say that, there is a great demand to develop(More)
Complex predicates (CPs) are a highly productive predicational phenomenon in Hindi and Urdu and present a challenge for deep syntactic parsing. For CPs, a combination of a noun and light verb express a single event. The combinatorial preferences of nouns with one (or more) light verb is useful for predicting an instance of a CP. In this paper, we present a(More)
