The aim of this paper is to compare the discourse structures proposed in RST, SDRT and dependency DAGs which extend the semantic level of MTT for discourses. The key question is the following: do these formalisms allow the representation of all the discourse structures which correspond to felicitous discourses and exclude those which correspond to infelicitous discourses? Hence the term of “str...

Semantic Orientation refers to the positive or negative attitude, standpoint or opinion on a certain person, object or affair. It is of degree diversity and combinability. Rule-based computation of SO for Chinese sentence, after pre-processing the input sentence in lexical and dependency syntax analysis, takes advantage of the syntax analysis results and combines the pre-compiled dictionary res...

We describe the design, development, and API for two discourse parsers for Rhetorical Structure Theory. The two parsers use the same underlying framework, but one uses features that rely on dependency syntax, produced by a fast shift-reduce parser, whereas the other uses a richer feature space, including both constituentand dependency-syntax and coreference information, produced by the Stanford...

In this paper, we deal with information retrieval approach based on language model paradigm, which has been intensively investigated in recent years. We propose, implement, and evaluate an enrichment of language model employing syntactic dependency information acquired automatically from both documents and queries. By testing our model on the Czech test collection from Cross Language Evaluation...

The paper casts a critical eye on those dependency grammars (DGs) that view linear order as derived from hierarchical order. It argues that MTT is such a DG insofar as language synthesis begins with a semantic representation, progresses through syntactic representations that lack linear order, and then proceeds to the morphological and phonological representations that include linear order. The...

This paper raises and discusses three questions about the structure of Meaning-Text Theory, based on consideration of the role that paradigmatic Lexical Functions play in its model of the lexicon: Is the paradigmatic-syntagmatic distinction meaningful? Do paradigmatic LFs represent redundant semantic information (and if so, is the redundancy justified)? And finally, might definitions of lexemes...

In this example, however, by the moment the word is has been read, the word p r o b l e m is already engaged in other strongly predicted constructions, namely the prepositional phrase of" this p r o b l e m and even the whole noun phrase the s o l u t i o n o f this p r o b l e m . A conflict arises, and plausibility of the new hypothesis becomes much lower. Such syntactic relations may concern...

We describe multi-lingual text generation as an alternative to automatic translation in specified technical sublanguages, illustrating the notion with the implemented RAREAS-2 system for synthesizing marine weather forecasts in English and French. We then review the Meaning-Text Theory (MTT) of Mel'cuk et al. as we have applied it to text generation in the GOSSIP system for producing English re...

In this paper we discuss the semantics of adjectives from the perspective of a Modern Type Theory (MTT) with an adequate subtyping mechanism. In an MTT, common nouns (CNs) can be interpreted as types and, in particular, CNs modified by intersective and subsective adjectives can be given semantics by means of Σ-types. However, an interpretation of CNs as types would not be viable without a prope...

Corpus-based treebank annotation is known to result in incomplete coverage of midand low-frequency linguistic constructions: the linguistic representation and corpus annotation quality are sometimes suboptimal. Large descriptive grammars cover also many midand low-frequency constructions. We argue for use of large descriptive grammars and their sample sentences as a basis for specifying higher-...
