Authors: Wicaksana Endra Maulia , Rijati Nova
Published: February 2025

The development of e-commerce in Indonesia has led to an increase in the number of users of product delivery services to deliver their customers' orders to their destination. SiCepat Ekspres is the number one fastest delivery service in Indonesia, besides JNE and JNT Express. The study aims to evaluate the performance of sentiment analysis methods in identifying and classifying sentiments related to SiCepat Ekspres. Data from Twitter media as many as 10,000 dataset records. The experimental results show that Random Forest with SMOTE is the best method, as it has the highest accuracy (91.10%), followed by improvements in precision, recall, and F-measure. SVM with SMOTE is in second place, with 90.50% accuracy and stable performance in other metrics. Naive Bayes with SMOTE shows improvement, but its performance remains slightly below Random Forest and SVM, with an accuracy of 88.80%.

Authors: Nevrada Nofsa Atia , Syaputra Muhammad Adie
Published: February 2025

This study aims to analyze the sentiment of Telegram application reviews on the Google Play Store using the Support Vector Machine (SVM) algorithm. From a total of 14,700,000 initial reviews, a sampling technique was carried out to obtain 400 review data, which then went through the pre-processing stage to produce 345 review data to be classified. The SVM model used showed good performance with an accuracy of 81.16%, precision in the positive class reached 93%, recall in the negative class of 94%, and an average f1-score of around 81%. However, there was a discrepancy between the high rating and the content of the review, which highlighted the existence of high-rated reviews that contained criticism or vice versa. The confusion matrix analysis also showed some misclassification, where reviews should be categorized as positive sentiment but detected as negative, and vice versa. This research is expected to provide valuable feedback for Telegram application developers to improve the quality of service, although the results of this analysis have not been fully discussed in practice. The limitation of this study is that it only tested reviews that used Indonesian, which limited the scope of the findings to the context of local users.

The analysis of the detection capabilities of small unmanned aerial vehicles (UAVs) with an effective scattering area of σ ≤ 0.01 m2 by radar stations (radars) in service in many countries of the World is carried out. Since the range of the UAV is limited to a range of 10-30 km, the article provides energy calculations for these ranges. The article evaluates the operation of pulse and narrowband radars in detection mode with the receiver set to the frequency of the rotating propeller of the aircraft. The narrowband mode is implemented by switching the polarization plane of the antenna's radiation pattern, or its radiation pattern, relative to the equi-signal zone. This mode significantly reduces the required radiation power of the transmitter by reducing the bandwidth of the receiver. Calculations of the spectral characteristics of rotating screws are performed, a comparative assessment of the radiated power of radar transmitters when operating in pulsed and narrowband modes is given. For the latter case, a phase-based range measurement method is proposed. The results of experimental studies are presented.
Graph Neural Network based elastic deformation emulators for magmatic reservoirs of complex geometries
Authors: Wang Taiyi A. , McBrearty Ian , Segall Paul
Published: February 2025

Measurements of volcano deformation are increasingly routine, but constraining complex magma reservoir geometries via inversions of surface deformation measurements remains challenging. This is partly due to deformation modeling being limited to one of two approaches: computationally efficient semi-analytical elastic solutions for simple magma reservoir geometries (point sources, spheroids, and cracks) and computationally expensive numerical solutions for complex 3D geometries. Here, we introduce a pair of Graph Neural Network (GNN) based elasto-static emulators capable of making fast and reasonably accurate predictions (error upper bound: 15 %) of surface deformation associated with 3D reservoir geometries: a spheroid emulator and a general shape emulator, the latter parameterized with spherical harmonics. The emulators are trained on, and benchmarked against, boundary element (BEM) simulations, providing up to three orders of magnitude speed up compared to BEM methods. Once trained, the emulators can generalize to new reservoir geometries statistically similar to those in the training data set, thus avoiding the need for re-training, a common limitation for existing neural network emulators. We demonstrate the utility of the emulators via Bayesian Markov Chain Monte Carlo inversions of synthetic surface deformation data, showcasing scenarios in which the emulators can, and can not, resolve complex magma reservoir geometries from surface deformation. Our work demonstrates that GNN based emulators have the potential to significantly reduce the computational cost of inverse analyses related to volcano deformation, thereby bringing new insights into the complex geometries of magmatic systems.
Service Delivery Models: Impacts for Students With and Without Disabilities

Published: February 2025

Students with and without disabilities may be educated across various service delivery models (SDMs): general education, cotaught, pull-out, and self-contained. Still, evidence for their relative effectiveness at scale remains limited. Using longitudinal administrative data from Indiana, we measured the effect of different SDMs on test scores, attendance, and disciplinary incidents. We leveraged within-student variation in SDM assignments and differences across students, applying student fixed effects and lagged outcomes models, which bound the causal effect within a narrow, policy-relevant range. Students with disabilities performed better in less restrictive environments, although the magnitude was often modest and varied across SDMs. Coteaching had a positive impact on students without disabilities. This work contributes to our understanding of inclusive practices’ effectiveness as experienced statewide.
Randomised Controlled Trials in Educational Research
Authors: Torgerson Carole , Torgerson David J.
Published: February 2025

It has been more than twenty years since we lamented the lack of large, pragmatic, randomised controlled trials to evaluate novel educational policies. Whilst there was an evaluation landscape in education this was dominated by quasi-experimental designs that could not, by their very nature, enable the minimisation of selection bias. Consequently, even well conducted quasi-experiments have the potential to be misleading as their results may be influenced by selection effects. However, over the last 20 years there has been a sea change, with large pragmatic randomised controlled trials dominating the evaluation landscape especially in the United Kingdom (UK) and United States (US). Key funding agencies for educational evaluations in both countries encourage the adoption and prioritisation of ‘true’ experimental designs. Furthermore, the methodological quality of recent experiments is high with trial registration, large sample sizes, independent randomisation and blinded pre and post testing featuring in many if not most of the published examples. In this paper we summarise the massive progress in the quality and quantity of educational trial design over the last 20 years. We also describe innovative trial designs that have and are being used to control for various confounders that can still be present in a trial design despite adequate randomisation.
Measuring Shifts in Attentional Bias Following Satiety: A Within-Subject Eye-Tracking Study in Healthy-Weight Adults

Hunger and satiety are key physiological states that regulate food intake and contribute to the maintence of body weight. Identifying appetite phenotypes, such as reduced satiety sensitivity, holds significant potential for developing personalized prevention and treatment strategies for obesity. However, a key challenge in obesity research is the lack of objective, quantitative tools to measure the physiological states of hunger and satiety. We developed the Food Attentional Bias (FAB) task, a novel, free-viewing eye-tracking paradigm designed to capture shifts in attentional bias toward food (should we add compared with other stimuli?). In this study, we investigated within-subject changes in attentional bias toward food before and after eating in a cohort of healthy-weight individuals (n=??) using the FAB Task. Our results indicate a marked decrease in dwell time to food stimuli after eating, regardless of counterbalanced condition, BMI, sex, or age. A linear mixed model for relative dwell time revealed a significant effect of the AOI (area of interest) category on dwell time (F(4, 5538) = 43.520, p < .001). Post hoc comparisons for the AOI * Meal interaction revealed that the dwell times for food AOIs were significantly greater premeal than postmeal (mean difference = 0.070, p < .001). These findings suggest that as the body’s satiety signals increase postmeal, the motivational value of food decreases, leading to a reduction in attentional bias toward food stimuli. This dynamic recalibration of attention may act as an objective physiological marker of satiety, illustrating how internal physiological states influence attention allocation following food consumption.
Understanding Speech in ''Noise'' or Free Energy Minimization in the Soundscapes of the Anthropocene
Authors: Strauss Daniel J. , Francis Alexander L. , Schäfer Zeinab , Latzel Matthias , Corona-Strauss Farah I. , Launer Stefan
Published: February 2025

Listening to speech in the presence of irrelevant sounds is ubiquitous in the modern world, but is generally acknowledged to be both effortful and unpleasant. Here we argue that this problem arises largely in circumstances that our human auditory system has not evolved to accommodate. The soundscapes of the Anthropocene are frequently characterized by an overabundance of sound sources, the vast majority of which are functionally irrelevant to a given listener. The problem of listening to speech in such environments must be solved by an auditory system that is not optimized for this task. So what does it mean to ''restore'' hearing for people with hearing loss? How might evolution optimize the sense of hearing for our world today? Building on our previous work on the two-competitor model and incorporating an active inference approach using free energy minimization, we argue that the answers to these question have implications not just for the study of human audition, but also for the development and broad awareness of hearing aids and cochlear implants, as well other auditory technologies such as ear buds, immersive auditory environments, and systems for human-machine interaction.
Evaluating the role of age on speech-in-noise perception based primarily on temporal envelope information

Published: February 2025

Acoustic amplitude modulation (AM) patterns carry important information, particularly in speech. AM masking, influenced by frequency selectivity in the modulation domain, is considered a crucial factor for speech intelligibility in noisy environments. Based on recent evidence suggesting an age-related decline in AM frequency selectivity, this study investigated whether increased AM masking in older listeners is associated with reduced speech intelligibility. Speech reception thresholds (SRTs) were measured using tone-vocoded speech and maskers with no modulation, broadband AM, or narrowband AM at varying modulation frequencies. AM masked thresholds were assessed for a 4-Hz target modulation frequency. The study included young (N=14, 19-25 years) and older (N=14, 57-79 years) listeners with normal hearing. It was hypothesized that SRTs would be higher for the older group with modulated maskers and that the age-related increase in SRT would depend on the masker’s modulation frequency content. The speech intelligibility results showed that maskers with broadband AM produced higher SRTs than unmodulated maskers. However, SRTs varied little with masker-modulation center frequency across the range tested (2-32 Hz). While older listeners exhibited lower AM frequency selectivity than young listeners, they did not consistently exhibit higher SRTs than their young counterparts across maskers. However, there was a trend for the effect of age to be greater for maskers with broadband AM than for unmodulated maskers. Overall, despite supportive trends, the results do not conclusively demonstrate that older listeners are more susceptible than young listeners to AM masking of speech.
Characterizing internal models of the visual environment
Authors: Kaiser Daniel , Engeser Micha
Published: February 2025

Despite the complexity of real-world environments, natural vision is seamlessly efficient. To explain this efficiency, researchers often use predictive processing frameworks, in which perceptual efficiency is determined by the match between the visual input and internal models of what the world should look like. In natural scene processing, predictions derived from our internal models of a scene should play a particularly important role, given the highly reliable statistical structure of our environment. Despite their importance for scene perception, we still do not fully understand what is contained in our internal models of the environment. Here, we argue that the current literature on scene perception disproportionately focuses on an experimental approach that tries to infer the contents of internal models from arbitrary, experimenter-driven manipulations in stimulus characteristics. To make progress, additional participant-driven approaches are needed: Rather than solely relying on manipulating the input to the visual system, researchers should adopt a complementary approach focusing on participants' descriptions of what they believe constitutes a typical scene. Such descriptions promise to capture the contents of internal models in more unconstrained ways on the level of individual participants. Critically, the descriptions of internal models can in turn be used to predict the efficiency of scene perception. We highlight recent studies on memory and perception using innovative methodologies like line drawings to characterize internal representations. These emerging methods show that it is now time to also study natural scene perception from a different angle – starting with a characterization of individual’s expectations about the world.
Clivadas é que à luz da cartografia sintática
Authors: Matias Silveira Damaris
Published: February 2025

Estruturas clivadas são sentenças utilizadas para focalizar elementos sintáticos através de movimento não argumental e de itens focalizadores, como a cópula e o complementizador que. O português brasileiro (PB) dispõe de clivadas canônicas, que apresentam a sequência linear “cópula+foco+que+IP”. Entretanto, a literatura menciona a existência das chamadas “clivadas invertidas”, que apresentam o foco em posição inicial. Com base no Programa Cartográfico, que concebe os elementos sintáticos como objetos complexos e hierarquicamente organizados, propomos uma análise para essas construções, as quais chamaremos de “Clivadas é que”, uma vez que não a consideramos uma versão invertida das clivadas canônicas, mas uma estrutura independente em que a cópula e o complementizador figuram como itens funcionais.Palavras-chave: Clivadas.

Produção e processamento de variantes: o caso dos pronomes acusativos de terceira pessoa em português brasileiro
Authors: Pereira Ronan , Silva Mariana , Rosa Catarina
Published: February 2025

Dadas as duas possibilidades de realização lexical dos pronomes acusativos de terceira pessoa no português brasileiro, um normalmente adquirido pelas crianças (pronome forte) e outro adquirido via instrução escolar (pronome clítico), este estudo procurou compreender se a produção da variante clítica pode ser estimulada devido ao grau de monitorização da fala e se essa variação se observa no processamento destes pronomes. Por meio de duas tarefas de produção (uma espontânea e uma induzida) e uma de processamento (sentence-matching), observou-se que o pronome forte é priorizado na fala espontânea e o pronome clítico é priorizado na fala em situações mais monitorizadas. A tarefa de sentence-matching não apresentou diferenças no tempo de reação à leitura de itens com estes dois pronomes, o que poderá advir ou da inibição do pronome forte, ou da facilitação do pronome clítico após o seu uso.Palavras-chave: Português brasileiro. Pronomes acusativos de terceira pessoa. Processamento da variação linguística. Monitor sociolinguístico.

The Establishment of the Bolshevik Occupation Regime in Eastern Galicia, Volyn, Northern Bukovyna and Bessarabia in 1939-1953 as a Form of Sovietization
Authors: Yurii Mykhailo
Published: February 2025

According to rough calculations, the Soviet authorities repressed 3-4 times more people than the Nazis in the German occupation zone, where the population was almost twice as large as in the territories annexed to the USSR. The large-scale repressions of Stalinism had all the signs of being classified as a crime against humanity under international law. The unification of Ukrainian lands within the Ukrainian SSR is assessed ambiguously.After the events of September 1939 and June 1940, the western Ukrainian lands of Northern Bukovyna and Bessarabia joined Soviet Ukraine. Politicians and historians of that time assessed this fact as the fulfillment of the eternal dream of many generations of Ukrainians to reunify in a single Ukrainian SSR. The arrival of the Red Army was interpreted by them as «liberating». From today’s point of view, two opposite historical events merged in these fields: on the one hand, the realization of Ukrainians’ aspirations for the concentration of all ethnic Ukrainian lands in a single state; on the other – brutal disregard for the norms of international law, undisguised aggression, which was met with an unfavorable attitude from the Western states. The forced integration of Western Ukraine, Northern Bukovyna, and Bessarabia into the system of «barrack socialism» that prevailed in the USSR was accompanied by unprecedented repression, violations of laws and human rights, and deep social, economic, and spiritual deformations. Starting from the end of 1939, at first slowly, and then with increasing speed, at the end of 1940 and further in the first half of 1941, the flywheel of terror was spun, which became especially brutal in the second stage of Sovietization after the expulsion of the fascist troops, which led to the full Sovietization of the annexed regions.For the first time in several centuries, Ukrainians found themselves within the borders of one state, but the repressive regime convinced most Western Ukrainians that the future did not lay in such a union, but in the creation of an independent, united Ukrainian state. Apparently, with this in mind, the prominent Ukrainian artist O. Dovzhenko noted in his diary in 1942: «Ah, if I had enough strength and time, I would write a novel about the liberation of Western Ukraine, about the reunification of our peoples... And as Ukrainian people, I actually had nothing to do with it...».
The Growth and Decline of German Scientific Publishing 1850–1945
Authors: Sarkowski Heinz
Published: February 2025

The development of commercial scientific publishing companies in Germany commenced in the middle of the 19th century. University and Academy publishers never had a chance. Scientific society publishers emerged only in 1921/1923 during inflation, but had little impact. German publishers dominated in particular in Mathematics, Physics and Chemistry. In 1909, 45% of the articles covered by the Chemical abstracts were from German publications. Until 1933 the German language was the “lingua franca” of Europe's scientific community. The export of German science publishers was significant, and in 1930 around 60% of Springer Verlag's turnover came from export. The international significance of German science can be seen from the large number of Nobel Prizes bestowed on it: 15 German scientists were recipients from 1901 to 1915, 16 from 1918 to 1932. After 1933 many highly qualified scientists fled the Nazis and found refuge in the Western world, constituting the start of the decline of German science. During World War II German science literature was reprinted on a large scale and sold worldwide. After the War the German language had definitively lost its world significance and German companies concentrated thereafter on production of textbooks and journals for the home market. In the sixties they also commenced publication of research literature in English.

Published: February 2025

Focusing the development of non-industrial robotics in the last decade the growing impact of service and entertainment robots for daily life has emerged from pure science fiction to a serious scientific subject. But still many questions in how to solve everyday tasks like laying the table or even “simpler” detecting objects in unstructured areas with varying lighting conditions are unsolved. Hence the strong need to evaluate and exchange different approaches and abilities of multiple robotic demonstrators under real world conditions is also a crucial aspect in the development of system architectures. In this paper an architecture will be described providing strong support for simple exchange and integration of new robot abilities.
Influence of correction objectives on the optimal scoliosis instrumentation strategy: A preliminary study
Authors: Majdouline Y.  , Aubin C.-É.  , Labelle H.
Published: February 2025

In three recent studies we have shown how different correction objectives from a group of experienced spine surgeons add to the variability in AIS instrumentation strategies. This study examined the effect of correction objectives of three surgeons on the optimal instrumentation strategy. An optimization method using six instrumentation design parameters (e.g. limits of the instrumented segment, number, type and location of implants and rod shape) that were manipulated in a uniform experimental design framework was linked to a patient-specific biomechanical model to analyze the effects of a specific instrumentation configuration. The optimization cost function was formulated to maximize correction in the three anatomic planes and with minimal number of instrumented levels. Three surgeons from the Spinal Deformity Study Group provided their respective correction objectives for a single patient (56° thoracic and 38° lumbar Cobb angle). For each surgeon, 702 surgical configurations were iteratively simulated using a biomechanical model. The influence of the three different correction objectives on the optimal surgical strategy was evaluated. The resulting optimal fusion levels were T2-L4, T4-L2, and T4-L1. A Wilcoxon non parametric test analysis showed that fusion levels and the location of implants significantly were influenced by the correction objectives strategies (p<0.05). The optimal number of implants although different (12 vs.11 vs.10) was not statistically significant (p>0.1). Thus different surgeon-specified correction objectives produced different optimal instrumentation strategies for the same patient.
BRACE MAP, a proposal for a new classification of braces
Authors: Negrini S.  , Zaina F.  , Atanasio S.
Published: February 2025

Braces today are named according to the author's name or town. The existing classification of braces considers only the anatomical spinal section involved (C: cervical; T: thoracic; L: lumbar; S: sacral; Orthosis). The absence of a more detailed classification do not allow to really distinguish between the different braces and to have a common language between the conservative treatment experts. Our aim was to propose and verify a new classification of braces. We developed the classification and applied it to 13 different braces (Boston, Charleston, Cheneau 2000, Lapadula, Lyonese, Maguelone, Milwaukee, PASB, Providence, Sforzesco, Sibilla, SpineCor, Triac). We considered the following items (acronym BRACE MAP): Building, Rigidity, Anatomical classification, Construction of the Envelope, Mechanism of Action, Plane of action. Each item is composed by 2 to 7 classificatory elements defined using one or maximum two letters, so that from the classification it is possible to come back to the brace characteristics. Out of the 13 braces considered, BRACE MAP did not allow to differentiate only two. This first proposal needs to be refined through Consensus and discussions that are already underway in the international Society On Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT); nevertheless, BRACE MAP appears to be useful in distinguishing between the existing braces.

The value of side bending test is important in the assessment of curve mobility and planning of scoliosis surgery. Our hypothesis is that side-bending test could also assess the reducibility of external asymmetry in the prediction of surgical outcome. However, the current method for analyzing trunk surface topography, based on horizontal cross-sections, is not suitable to side-bending. The purpose of this study was to develop a novel method to analyze the changes in external asymmetry in side-bending. The novel method consists in extracting the back valley curve, then defining cutting planes that are normal to the curve. The intersection between each cutting plane and the trunk surface defines a cross-section to be analyzed. Indices of external trunk asymmetry, such as the rotation of the tangent lines to the back and the rotation of the major axis of the cross-sections, are computed. When visiting the scoliosis clinic for their preoperative evaluation, patients had their 3D trunk surface geometry digitized with a multi-head Inspeck system in standing posture and in maximum voluntary right and left side-bending. For each patient, the surface reconstructions for the 3 acquisitions were analyzed with the proposed method. The standing geometry was also analyzed with the horizontal cross-section method. The resulting curves and indices were coherent with the observed deformations and changes between standing and side-bending. Comparison between the novel approach and the horizontal cross-section-based approach, for standing posture, indicated that the novel one tended to be more representative of the perceived asymmetry.

Low BMD and dysfunction of melatonin signaling pathway has been suggested as the possible key link to the spinal deformity in AIS. Prior studies shown that melatonin can influence and regulate skeletal growth and bone formation in human and animal models. However, there is a relative lack of direct evidence on the role of melatonin on AIS at the cellular and molecular level. To investigate the effect of melatonin on AIS osteoblasts at the cellular level. In vitro assays were performed with osteoblasts isolated from 7 girls with severe AIS and 7 controls. These were treated with different concentration of melatonin (0, 10−11, 10−9, 10−7, 10−5M). Cell proliferation was tested by MTT assay. As for differentiation, cells were cultured overnight in osteogenic medium. Then, they were given different concentration of melatonin for 3 days, prior to measuring the ALP activity. Moreover, mineralization of the matrix was qualitatively determined by alizarin red S staining after 18 days of culture. There was significant differences between control and AIS at the melatonin concentration of 10−9to 10−5M (p<0.05). In control, melatonin could stimulate proliferation when compared with the basal (p<0.05). Likewise, melatonin could also enhanced differentiation, with incubation overnight in osteogenic medium (p<0.05). Likewise, mineralized matrix was formed. However, none of the AIS osteoblasts could show any of the changes at the same concentration of melatonin. For the first time, we demonstrated there is a relative difference between AIS and control toward melatonin, which may play an important role in the etiopathogenesis of AIS.

Lower body mass index (BMI) and lower circulating leptin levels have been reported in girls with AIS. In this paper we evaluate skeletal sizes and asymmetries by higher and lower BMI subsets about the means for each of three groups of girls age 11–18 years: 1) normals, 2) school screening referrals, and 3) preoperative girls. Higher and lower BMI subsets, likely to have separated subjects with higher from those with lower circulating leptin levels, identify: 1) girls with relatively earlier and later menarche; 2) trunk width size greater in the higher than in the lower BMI subset, of all three groups; 3) abnormal upper arm length (UAL) asymmetries (right minus left) in the lower BMI subset of the preoperative girls; and 4) in thoracic AIS of screened and preoperative girls, Cobb angle and apical vertebral rotation each significantly and positively correlate with UAL asymmetry in the lower BMI subset but not in the higher BMI subset. In preoperative girls, the lower BMI subset shows the combination of relatively reduced pelvic width and abnormal UAL asymmetry, suggesting that both are linked to lower circulating leptin levels. An earlier puberty with hormonal changes provides a plausible explanation for the larger trunk width at the shoulders and pelvis especially at the younger ages in the higher BMI subsets. At the shoulders, this widening is driven by the ribcage which, in human evolution was acquired with decoupling of head and trunk movements required for efficient bipedal gait. The UAL asymmetry patterns within the groups and BMI subsets are not explained by hormonal mechanisms. It is hypothesized that 1) normal trunk widening of the thoracic cage by hormones in human adolescence is supplemented via the sympathetic nervous system under leptin-hypothalamic control influenced by energy stores (metabolic fuel); and 2) hypothalamic dysfunction with altered hypothalamic sensitivity to leptin through a SNS-driven asymmetric effect may create skeletal length asymmetries in upper arms, ribs, ilia and vertebrae, and initiate AIS. Additional mechanisms acting in the spine and trunk may be required for AIS to progress including 1) somatic nervous system dysfunction, 2) biomechanical spinal growth modulation, and 3) osteopenia.
Comparing Negotiation Strategies Based on Offers

Negotiation is a process between self-interested agents trying to reach an agreement on one or multiple issues in an ecommerce domain. The knowledge of an agent about the opponents' strategies improves the negotiation outcome. However, an agent negotiates with incomplete information about its opponent. Given this, to detect the opponent's strategy, we can use the similarity between opponents' strategies. In this paper we present a method for measuring the similarity between negotiators' strategies. Offers are generated by the agent's strategy therefore our similarity measure is based on the history of offers in negotiation sessions. We extended the Levenshtein distance technique to detect similarity between strategies. We implement this measure and experimentally show that the result of using the measure improves the recognition of the opponent's strategy.
Sub Node Extraction with Tree Based Wrappers

Published: February 2025

String based as well as tree based methods have been used to learn wrappers for extraction from semi-structured documents (e.g., HTML documents). Previous work has shown that tree based approaches perform better while needing less examples than string based approaches. A disadvantage is that they can only extract complete text nodes, whereas string based approaches can extract within text nodes. This paper proposes a hybrid approach that combines the advantages of both systems and compares it experimentally with a string based approach on some sub node extraction tasks.
A Method for Classifying Vertices of Labeled Graphs Applied to Knowledge Discovery from Molecules
Authors: Pennerath Frédéric  , Polaillon Géraldine  , Napoli Amedeo
Published: February 2025

The article proposes a generic method to classify vertices or edges of a labeled graph. More precisely the method computes a confidence index for each vertex v or edge e to be a member of a target class by mining the topological environments of v or e. The method contributes to knowledge discovery since it exhibits for each edge or vertex an informative environnement that explains the found confidence. When applied to the problem of discovering strategic bonds in molecules, the method correctly classifies most of the bonds while providing relevant explanations to chemists. The developed algorithm GemsBond outperforms both speed and scalability of the learning method that has previously been applied to the same application while giving similar results.
Observation-Subsumption Checking in Similarity-Based Diagnosis of Discrete-Event Systems
Authors: Lamperti Gianfranco  , Zanella Marina
Published: February 2025

In similarity-based diagnosis of discrete-event systems the knowledge generated for solving a previous diagnostic problem can be reused to solve a new one, provided the two problems are similar. Problem-similarity requires that the temporal observation relevant to the new problem be subsumed by the temporal observation relevant to the old one. A temporal observation encompasses the (uncertain) events observed over a time interval and their (uncertain) reciprocal temporal order. Such an observation has been produced by one out of several distinct certain sequences of observable events, with each of such sequences being a sentence of the regular language of the observation. An observation subsumes another if its regular language contains the regular language of the other. However, checking observation-subsumption by following its formal definition is time consuming. In order to speed up the process, an alternative technique is proposed, which is based on the notion of coverage and exploits a number of necessary conditions, as well as a sufficient condition, for subsumption to hold. Such conditions can be directly checked on the properties of the given observations, without any need to appeal to the language theory. Experimental evidence confirms the efficiency of subsumption-checking via coverage.
Temporal Logic Patterns for Querying Qualitative Models of Genetic Regulatory Networks

Published: February 2025

Formal verification based on model checking provides a powerful technology to query qualitative models of dynamical systems. The application of model-checking approaches is hampered, however, by the difficulty for non-expert users to formulate appropriate questions in temporal logic. In order to deal with this problem, we propose the use of patterns, that is, high-level query templates capturing recurring questions which can be automatically translated to temporal logic. We develop a set of patterns for the analysis of qualitative models of genetic regulatory networks, which are sufficiently generic though to be useful in other application domains. The applicability of the patterns has been investigated by the analysis of a model of the network of global regulators controlling the carbon starvation response in Escherichia coli.
