Multiword expressions (MWEs) present particular and distinctive semantic properties, hence their automatic extraction receives special attention from the natural language processing (NLP) and corpus linguistics community, and is still an active research area. Unfortunately, the creation of necessary resources for this task is quite rigorous and many languages suffer from the lack of these; as i...

Medical practitioners and healthcare workers rely on information accuracy in academic journals. Some Covid-19 papers contain “tortured phrases”, nonstandard English expressions, or imprecise erroneous terms, that give the impression of jargon but are not. Most post-publication attention paid to literature has focused biomedical aspects, validity claims, robustness data, little been published li...

This contribution explores the subgroup of text structuring expressions with the form preposition + demonstrative pronoun, thus it is devoted to an aspect of the interaction of coreference relations and relations signaled by discourse connectives (DCs) in a text. The demonstrative pronoun typically signals a referential link to an antecedent, whereas the whole expression can, but does not have ...

The growing amount of textual information available electronically has increased the need for high performance retrieval. The use of phrases was long seen as a natural way to improve retrieval performance over the common document models that ignore the sequential aspect of word occurrences in documents, considering them as “bags of words”. However, both statistical and syntactical phrases showe...

Word-sense recognition and disambiguation (WERD) is the task of identifying word phrases and their senses in natural language text. Though it is well understood how to disambiguate noun phrases, this task is much less studied for verbs and verbal phrases. We present Werdy, a framework for WERD with particular focus on verbs and verbal phrases. Our framework first identifies multi-word expressio...

This paper presents some arguments against a unilateral account of numerically quantified noun phrases and for a bilateral account of such expressions. It is proposed that where numerically quantified noun phrases give rise to at least readings, this is the result of one of two forms of pragmatic reasoning. To that end, the paper develops an independently motivated account of specificity and ex...

Extracting from a given document collection what we call “domain-specific” key terms/phrases is a challenging task. By “domainspecific” key terms/phrases we mean words/expressions representative of the topical areas specific to the focus of a document collection. For example, when a collection is related to academic research (i.e., its focus is related to topics dealing with academic research),...

This paper elaborates a model for representing semantic calendar expressions (SCEs), which correspond to the intensional meanings of natural-language calendar phrases. The model uses finite-state transducers (FSTs) to mark denoted periods of time on a set of timelines represented as a finite-state automaton (FSA). We present a treatment of SCEs corresponding to quantified phrases (any Monday; e...

the non-commuting graph $nabla(g)$ of a non-abelian group $g$ is defined as follows: its vertex set is $g-z(g)$ and two distinct vertices $x$ and $y$ are joined by an edge if and only if the commutator of $x$ and $y$ is not the identity. in this paper we 'll prove that if $g$ is a finite group with $nabla(g)congnabla(bs_{n})$, then $g cong bs_{n}$, where $bs_{n}$ is the symmetric group of degre...
