“…Hence, uncertainty and vagueness need to be communicated. Though recent work in Natural Language Understanding has addressed the task of extracting temporal relations in medical free text [107], less attention has been paid to the expression of uncertainty in NLG systems using mechanisms such as vague predicates [120] and modals [69]. The use of some of these mechanisms is exemplified in the following free text fragment:…”

Contemporary Neonatal Intensive Care Units collect vast amounts of patient data in various formats, making efficient processing of information by medical professionals difficult. Moreover, different stakeholders in the neonatal scenario, which include parents as well as staff occupying different roles, have different information requirements. This paper describes recent and ongoing work on building systems that automatically generate textual summaries of neonatal data. Our evaluation results show that the technology is viable and comparable in its effectiveness for decision support to existing presentation modalities. We discuss the lessons learned so far, as well as the major challenges involved in extending current technology to deal with a broader range of data types, and to improve the textual output in the form of more coherent summaries.

“…) (мога, може, трябва, започвам, продължавам, спирам и др.). Модалните глаголи могат да се разглеждат като оператори по отношение на ситуацията, представена в подчиненото изречениe (Klabunde 2007), което е в синхрон и с традицията в българската граматика. В български могат да се разделят на две групи: такива, които присъединяват субектно комплементно изречение (може, трябва, необходимо е, възможно е и др.)…”

Целта на изследването е да се представят основни елементи от типологичния анализ на комплементните изречения в български език, като се изходи от някои традиционно използвани конвенции и се предложи класификация, която се основава на вида на семантичните отношения между простите изречения. Последователно са разгледани начините за изразяване на релациите има комплемент -е комплемент на на лексикално, морфологично, синтактично, семантично и структурно равнище във връзка с: наличието на комплементизатор; интерпретацията на темпоралните характеристики на подчинения предикат в зависимост от темпоралните характеристики на главния; задължително словоредно разместване по отношение на каноничната структура; наличието на зависима интерпретацията на субекта на подчинения предикат от аргумент към главния предикат и редукцията на синтактичната структура на комплемента. Ключови думи: комплементност, семантични релации, лексикална маркираност, структурна маркираност 1. [Ще отида там] и [ще разговарям с един приятел]. 1 2. [Приемете го] или [го отхвърлете].

“…To our knowledge, the only recent approach to handling modals in NLG is [23], which focuses on the generation of deontic modals (those related to obligation, rather than epistemic certainty), in the CAN system, which advises students about university courses [24,23]. Klabunde's approach is based on a possible worlds framework [18], in which the truth of a modalised proposition is evaluated against a contextually determined set of relevant possible worlds or situations, ordered by their accessibility from the current world or situation.…”

In NLG systems, temporal uncertainty in raw data can hamper the inference of temporal and causal relationships between events and thus impact the quality of the generated texts. In this paper, we introduce a framework to represent and reason with temporal uncertainty based on possibility theory and propose a model that uses the outcomes of such temporal reasoning to select linguistic expressions to convey uncertainty to the reader. Our model is based on Fuzzy Temporal Constraint Networks (FTCN) and our work is based on the assumption that uncertainty should be communicated to an end user. The model we propose is grounded in experimental data from three languages. We present a large-scale empirical study that investigates the conditions that influence human subjective uncertainty in reasoning about temporal relations. Based on this, we also construct a classifier to select expressions to convey uncertainty, based on possibility and necessity values. We then present an evaluation which shows that the predictions of the FTCN model correlate well with human subjective uncertainty in different scenarios. An evaluation of our temporal expressions classifier also suggests good results, compared to human selection of linguistic expressions, as compared to baseline models.
