A significant challenge in Text-to-Speech (TtS) synthesis is the formulation of the prosodic structures (phrase breaks, pitch accents, phrase accents and boundary tones) of utterances. The prediction of these elements robustly relies on the accuracy and the quality of error-prone linguistic procedures, such as the identification of the part-of-speech and the syntactic tree. Additional linguisti...

The paper describes the ALVIS annotation format and discusses the problems that we encountered for the indexing of large collections of documents for topic specific search engines. This paper is exemplified on the biological domain and on MedLine abstracts, as developing a specialized search engine for biologist is one of the ALVIS case studies. The ALVIS principle for linguistic annotations is...

The paper characterizes natural language inferencing in the TIBAQ method of question-answering, focussing on three aspects: ~i) specification of the structures on which the inference rules operate, (ii) classification of the rules that have been formulated and implemented up to now, according to the kind of modification of the input structure ti~e rules invoke, an~ (iii) discussion of some poin...

The JOS language resources are meant to facilitate developments of HLT and corpus linguistics for the Slovene language and consist of the morphosyntactic specifications, defining the Slovene morphosyntactic features and tagset; two annotated corpora (jos100k and jos1M); and two web services (a concordancer and text annotation tool). The paper introduces these components, and concentrates on jos...

In the performance of activities in an organization, communication plays a dominant role in that it allows people to coordinate their activities. They organize their activities by having conversations intending to initiate actions and report on them. The modeling of business communication is a central part in the communication-centered organizational modeling approach called dynamic essential m...

This paper discusses a requirements engineerings method that makes heavy use of linguistic instruments. The paper focuses on the validation phase in which syntactically veriied conceptual models are checked for their correspondence with the original intentions of the users. It is quite clear that the users themselves are the only ones who are capable of doing so. However, the users have severe ...

This paper presents experiments on how the performance of automatic keyword extraction can be improved, as measured by keywords previously assigned by professional indexers. The keyword extraction algorithm consists of three prediction models that are combined to decide what words or sequences of words in the documents are suitable as keywords. The models, in turn, are built using different def...
