Analysis of Verb Classes Used on The Observation Result Report (Morphology Study)

Abstract Background Recent advances in representation learning have enabled large strides in natural language understanding; However, verbal reasoning remains a challenge for state-of-the-art systems. External sources of structured, expert-curated verb-related knowledge have been shown to boost model performance in different Natural Language Processing (NLP) tasks where accurate handling of verb meaning and behaviour is critical. The costliness and time required for manual lexicon construction has been a major obstacle to porting the benefits of such resources to NLP in specialised domains, such as biomedicine. To address this issue, we combine a neural classification method with expert annotation to create BioVerbNet. This new resource comprises 693 verbs assigned to 22 top-level and 117 fine-grained semantic-syntactic verb classes. We make this resource available complete with semantic roles and VerbNet-style syntactic frames. Results We demonstrate the utility of the new resource in boosting model performance in document- and sentence-level classification in biomedicine. We apply an established retrofitting method to harness the verb class membership knowledge from BioVerbNet and transform a pretrained word embedding space by pulling together verbs belonging to the same semantic-syntactic class. The BioVerbNet knowledge-aware embeddings surpass the non-specialised baseline by a significant margin on both tasks. Conclusion This work introduces the first large, annotated semantic-syntactic classification of biomedical verbs, providing a detailed account of the annotation process, the key differences in verb behaviour between the general and biomedical domain, and the design choices made to accurately capture the meaning and properties of verbs used in biomedical texts. The demonstrated benefits of leveraging BioVerbNet in text classification suggest the resource could help systems better tackle challenging NLP tasks in biomedicine.

Similarity Relationships

This paper investigates set-theoretical transitive and intransitive similarity relationships in triplets of verbs that can be deduced from raters’ similarity judgments on the pairs of verbs involved. We collected similarity judgments on pairs made up of 35 German verbs and found that the concept of transitivity adds to the information obtained from collecting pair-wise semantic similarity judgments. The concept of transitive similarity enables more complex relations to be revealed in triplets of verbs. To evaluate the outcomes that we obtained by analyzing transitive similarities we used two previously developed verb classifications of the same set of 35 verbs based on the analysis of large corpora (Richter & van Hout, 2016). We applied a modified form of weak stochastic transitivity (Block & Marschak, 1960; Luce & Suppes, 1965; Tversky, 1969) and found that (1), in contrast to Rips’ claim (2011), similarity relations in raters’ judgments systematically turn out to be transitive, and (2) transitivity discloses lexical and aspectual properties of verbs relevant in distinguishing verb classes.

The chapter is a survey of the Nakh-Daghestanian family (also known as East Caucasian), one of the indigenous language families spoken in the Caucasus. The family comprises more than 30 languages, some of which are spoken by only a few hundred people and remain unwritten and/or underdescribed. The chapter provides general information about the sociolinguistic status of Nakh-Daghestanian languages and the history of their research as well as their phonology, morphology, syntax, and lexicon. The languages of the family have rich consonant systems and are morphologically ergative, head-final, with rich case systems, complex verbal paradigms, and pervasive gender-number agreement. Alongside the major transitive and intransitive lexical verb classes, verbs of perception and cognition with the dative experiencer subject usually comprise one or more minor valency classes with non-canonically marked subjects. Among valency-increasing derivations, the causative is the most prominent. The most typical subordination strategies are non-finite, making use of participles, converbs, infinitives and verbal nouns.

A pollen morphology study of the Gentianaceae Juss. of Reserva Florestal Adolpho Ducke (Manaus, Brazil) was performed. The pollen grains of the studied species varied morphologically in their pollen units (tetrads or monads), size (small, medium and large), shape (oblate, suboblate, oblate spheroidal, spheroidal, prolate spheroidal and prolate), polarity (heteropolar, isopolar or subisopolar), symmetry (bilateral or radial) and number and type of aperture (3-colporate and 1-3porate). In relation to ornamentation, pollen grains had a sexine that was psilate in the Voyria species, microreticulate in Voyriella parviflora and reticulate heterobrochate in Tachia grandiflora and Irlbachia alata. The exine in I. alata showed great variability in the size and shape of the lumina, in addition to clavae of various sizes in the mesocolpium and apocolpium areas. In Tachia grandiflora, besides to long colpi, the heterobrochate exine demonstrated an increase in the lumina in the mesocolpium areas that decreased considerably in the apocolpium areas. In the species of Voyria, the pollen grains showed differences in shape, polarity and the number of apertures, which were spherical, isopolar and 3-porate in Voyria spruceana; prolate/oval, heteropolar and 1-porate in Voyria tenella; and oblate/elliptical (reniform), heteropolar and 2(3)-porate in Voyria aphylla and Voyria caerulea. The variations in pollen morphology and the peculiar characteristics of the genus suggest that Voyria should be treated as a unique taxon within Gentianaceae.
