Distributed Representations of Lexical Sets and Prototypes in Causal Alternation Verbs
Lexical sets are sets of words filling a specific argument position of a verb in one of its senses. They can be extracted from corpora automatically. The purpose of this paper is demonstrating that the properties of lexical sets are mirrored by their distributed vector representations. This provides insights onto many linguistic phenomena, such as the causative-inchoative alternation in the verbal domain. A first experiment aims at investigating the internal structure of the sets, whose meanings are known to be radial and continuous categories cognitively. In particular, we establish an equivalence between the prototype of a set of words and the centroid of a set of vectors. A second experiment shows that the distance between the intransitive subject set and transitive object set is correlated with the spontaneity of the event expressed by the verb, defined in terms of morphological coding and frequency
Toward Data-Driven Collaborative Dialogue Systems: The JILDA Dataset
Today’s goal-oriented dialogue systems are designed to operate in restricted domains and with the implicit assumption that the user goals fit the domain ontology of the system. Under these assumptions dialogues exhibit only limited collaborative phenomena. However, this is not necessarily true in more complex scenarios, where user and system need to collaborate to align their knowledge of the domain in order to improve the conversation and achieve their goals.To foster research on data-driven collaborative dialogues, in this paper we present JILDA, a fully annotated dataset of chat-based, mixed-initiative Italian dialogues related to the job-offer domain. As far as we know, JILDA is the first dialogic corpus completely annotated in this domain. The analysis realised on top of the semantic annotations clearly shows the naturalness and greater complexity of JILDA’s dialogues. In fact, the new dataset offers a large number of examples of pragmatic phenomena, such as proactivity (i.e., providing information not explicitly requested) and grounding, which are rarely investigated in AI conversational agents based on neural architectures. In conclusion, the annotated JILDA corpus, given its innovative characteristics, represents a new challenge for conversational agents and an important resource for tackling more complex scenarios, thus advancing the state of the art in this field
Ovulation induction in young girls with menometrorragia: a safe and effective treatment
The prevalence of menometrorrhagia in fertile women is 11.4-13.2% and increases with aging. The presence of metrorrhagia is a relatively common cause of concern among adolescents and their parents, as well as a frequent cause of visits to emergency departments, gynaecologists, and pediatricians. Clomiphene is a selective estrogen receptor modulator (SERM) that increases the production of gonadotropins by inhibiting negative feedback on the hypothalamus.
Clomiphene is primarily used in the treatment of female infertility for ovulation induction to reverse oligoovulation or anovulation, as occurs in polycystic ovary syndrome.
Objective: The aim of our study was to evaluate the use of clomiphene citrate in ovulation induction, and therefore, in the cessation of bleeding in adolescents with menometrorrhagia in the absence of uterine, ovarian, or systemic pathologies.
Design: Cohort study.
Materials and methods: The study group was comprised of 50 subjects (age range, 13-16 years) with menometrorrhagia (bleeding >7 days in length with an average blood loss >80 ml). The treatment with clomiphene citrate at a dose of 50 mg/day for 5 days during the attack cycle, and from days 3 to 7 of three subsequent cycles, was offered to the patients.
Results: After three cycles of therapy, all patients had resolution of the menometrorrhagia and resumption of ovulatory cycles. No patient reported unwanted side effects.
Conclusion: We propose that low-dose clomiphene should be the first step in the treatment of adolescent dysfunctional bleeding (DUB)
Tuning DeSR for Dependency Parsing of Italian
DeSR is a statistical transition-based dependency parser that learns from a training corpus suitable actions to take in order to build a parse tree while scanning a sentence. DeSR can be configured to use different feature models and classifier types. We tuned the parser for the Evalita 2011 corpora by performing several experiments of feature selection and also by adding some new features. The submitted run used DeSR with two additional techniques: (1) reverse revision parsing, which addresses the problem of long distance dependencies, by extracting hints from the output of a first parser as input to a second parser running in the opposite direction; (2) parser combination, which consists in combining the outputs of different configurations of the parser. The submission achieved best accuracy among pure statistical parsers. An analysis of the errors shows that the accuracy is quite high on half of the test set and lower on the second half, which belongs to a different domain. We propose a variant of the parsing algorithm to address these shortcomings
Becoming JILDA
The difficulty in finding useful dialogic data to train a conversational agent is an open issue even nowadays, when chatbots and spoken dialogue systems are widely used. For this reason we decided to build JILDA, a novel data collection of chat-based dialogues, produced by Italian native speakers and related to the job-offer domain. JILDA is the first dialogue collection related to this domain for the Italian language. Because of its collection modalities, we believe that JILDA can be a useful resource not only for the Italian research community, but also for the international one.Negli ultimi anni l’utilizzo di chatbot e sistemi dialogici è diventato sempre più comune; tuttavia, il reperimento di dati di apprendimento adeguati per addestrare agenti conversazionali costituisce ancora una questione irrisolta. Per questo motivo abbiamo deciso di produrre JILDA, un nuovo dataset di dialoghi relativi al dominio della ricerca del lavoro e realizzati via chat da parlanti nativi italiani. JILDA costituisce la prima collezione di dialoghi relativi a questo dominio, in lingua italiana. Per gli aspetti metodologici e la modalità di raccolta dei dati, riteniamo che una simile risorsa possa essere utile ed interessante non solo per la comunità di ricerca italiana ma anche per quella internazionale
Domain Adaptation by Active Learning
We tackled the Evalita 2011 Domain Adaptation task with a strategy of active learning. The DeSR parser can be configured to provide different measures of perplexity in its own ability to parse sentences correctly. After parsing sentences in the target domain, a small number of the sentences with the highest perplexity were selected, revised manually and added to the training corpus in order to build a new parser model incorporating some knowledge from the target domain. The process was repeated a few times for building a new training resource partially adapted to the target domain. Using the new resource we trained three stacked parsers, and their combination was used to produce the final results

Il-6 Serum Levels and Production Is Related to an Altered Immune Response in Polycystic Ovary Syndrome Girls with Insulin Resistance
Polycystic ovarian syndrome (PCOS) is frequently characterized by obesity and metabolic diseases including hypertension, insulin resistance, and diabetes in adulthood, all leading to an increased risk of atherosclerosis. The present study aimed to evaluate serum and production of inflammatory markers in adolescent Sardinian PCOS. On the basis of HOMA findings, patients were divided into noninsulin resistant (NIR) and insulin resistant (IR), and were weight- and age-matched with healthy girls. Inflammatory cytokines (TNF-α, IL-6, Il-10, TGF-β) and lipokines (leptin, adiponectin), the reactant hs-CRP, and in vitro inflammatory lympho-monocyte response to microbial stimulus were evaluated. In healthy and PCOS subjects, leptin and hs-CRP were correlated with BMI, whereas adiponectin was significantly reduced in all PCOS groups. Although cytokines were similar in all groups, Interleukin-6 (IL-6) was significantly higher in IR PCOS. Moreover, in the latter group lipopolysaccharide-activated monocytes secreted significantly higher levels of IL-6 compared to NIR and control subjects. To conclude, IR PCOS displayed increased IL-6 serum levels and higher secretion in LPS-activated monocytes, whilst revealing no differences for other inflammatory cytokines. These results suggest that in PCOS patients an altered immune response to inflammatory stimuli is present in IR, likely contributing towards determining onset of a low grade inflammation
