AbstractSemantic technologies provide meaning to information resources in the form of machine-accessible structured data. Research over the past two decades has commonly focused on tools and interfaces for technical experts, leading to various usability problems regarding users unfamiliar with the underlying technologies – so-called nontechnical experts. Existing approaches to semantic technologies consider mostly consumers of structured data and leave out the creation perspective. In this work, we focus on the usability of creating structured data from textual resources, especially the creation of relations between entities. The research was conducted in collaboration with scholars from the humanities. We review existing research on the usability of semantic technologies and the state of the art of annotation tools to identify shortcomings. Subsequently we use the knowledge gained to propose a new interaction design for the creation of relations between entities to create structured data in the subject-predicate-object form. We implemented our interaction design and conducted a user study which showed that the proposal performed well, making it a contribution to enhance the overall usability in this field. However, this research provides an example of how technically sophisticated technology needs to be “translated” to make it usable for nontechnical experts. We need to extend this perspective in the future by providing more insight into the internal functioning of semantic technologies.

AbstractThe English dative alternation has received much attention in the literature on argument structure acquisition in children. However, the data on the acquisition of this alternation have consistently revealed a counter-intuitive pattern: children look more proficient with the lower frequency prepositional form of the dative than with the higher frequency double object form (Conwell & Demuth, 2007; Rowland & Noble, 2010). This may be because the DO dative typically occurs with pronominal argument types in first post-verbal position, which may result in an over-reliance on stereotyped forms (e.g., give + me) for early comprehension and production (Conwell, O'Donnell, & Snedeker, 2011). This paper presents three studies of the effects of the pronoun me on dative comprehension by three-year-olds. Children's comprehension of the DO dative improved significantly when the first post-verbal argument was pronominal; no other effects of pronoun use were significant. Children's experience affects their ability to use lexically general representations of syntactic structures.

Semantic Proximity

Identification deficits in dementia of the Alzheimer Type (DAT) often target specific classes of objects, sparing others. Using line drawings to uncover the etiology of such category-specific deficits may be untenable because the underlying shape primitives used to differentiate one line drawing from another are unspecified, and object form is yoked to object meaning. We used computer generated stimuli with empirically specifiable properties in a paradigm that decoupled form and meaning. In Experiment 1 visually similar or distinct blobs were paired with semantically close or disparate labels, and participants attempted to learn these pairings. By having the same blobs stand for semantically close and disparate objects and looking at shape–label confusion rates for each type of set, form and meaning were independently assessed. Overall, visual similarity of shapes and semantic similarity of labels each exacerbated object confusions. For controls, the effects were small but significant. For DAT patients more substantial visual and semantic proximity effects were obtained. Experiment 2 demonstrated that even small changes in semantic proximity could effect significant changes in DAT task performance. Labeling 3 blobs with “lion,” “tiger,” and “leopard” significantly elevated DAT confusion rates compared to exactly the same blobs labeled with “lion,” “tiger,” and “zebra.” In conclusion both visual similarity and semantic proximity contributed to the identification errors of DAT patients.

Recent evidence suggests that priming of objects across different images (abstract priming) and priming of specific images of an object (form-specific priming) are mediated by dissociable neural processing subsystems that operate in parallel and are predominantly linked to left and right hemispheric processing, respectively [Marsolek, C. J. Dissociable neural subsystems underlie abstract and specific object recognition. Psychological Science, 10, 111–118, 1999]. Previous brain imaging studies have provided important information about the neuroanatomical regions that are involved in form-specific and abstract priming; however, these techniques did not fully establish the functional significance of priming-related changes in cortical brain activity. Here, we used repetitive transcranial magnetic stimulation (rTMS) in order to establish the functional role of the right occipital cortex in form-specific priming [Kroll, N. E. A., Yonelinas, A. P., Kishiyama, M. M., Baynes, K., Knight, R. T., & Gazzaniga, M. S. The neural substrates of visual implicit memory: Do the two hemispheres play different roles? Journal of Cognitive Neuroscience, 15, 833–842, 2003]. Compared to no TMS and sham TMS, rTMS of the right occipital cortex disrupted immediate form-specific priming in a semantic categorization task. Left occipital rTMS, on the other hand, had no converse effect on abstractive priming. Abstract priming may involve deeper semantic processing and may be unresponsive to magnetic stimulation of a single cortical locus. Our TMS results show that form-specific priming relies on a visual word-form system localized in the right occipital lobe, in line with the predictions from divided visual field behavioral studies [Marsolek, 1999].

Foreign body self-insertion into the urethra is an uncommon paraphilia. Variety in object form, motivation, clinical presentation, complications, and treatment options is a rule. In childhood it is very rare, and it is attributed to curiosity or mental disorders so far. However, the internet impact on daily life of all age groups has created a new category of sexual behavior in childhood and adolescence, the “internet induced paraphilia.” Such is the case of an electrical cable inserted in the urethra of a 12-year-old boy reported here, which is representative of this kind of impact.
