Application Programming Interface (API) is a core technology that facilitates developers' productivity by enabling the reuse of software components. Understanding APIs and gaining knowledge about their usage are therefore fundamental needs for developers that impact a wide range of software development activities. This paper presents an approach to enable API users to explore, discover and learn about APIs through API topic issues discussed in Stack Overflow (SO), a widely used programming, community question-answering (CQA) site. Our work proposes an integrated API Knowledge Base (KB) and indexing technique that combines both SO API-related posts as well as other API learning resources collected from the Web (e.g., API video-tutorials from Youtube). The resulting indexed and enriched API community knowledge can be queried in a API-topic-issue driven manner using a simple yet powerful domain-specific language (DSL). We demonstrate the feasibility of our approach through Scout-bot, our tool for exploration and discovery of API topic issues.
应用程序编程接口(API)是一项核心技术,通过支持软件组件的重用来提高开发人员的工作效率。因此,理解api并获得有关其使用的知识是影响广泛软件开发活动的开发人员的基本需求。本文提出了一种方法,使API用户能够通过Stack Overflow (SO)中讨论的API主题问题来探索、发现和学习API, Stack Overflow (SO)是一个广泛使用的编程、社区问答(CQA)网站。我们的工作提出了一个集成的API知识库(KB)和索引技术,该技术结合了SO API相关的帖子以及从Web收集的其他API学习资源(例如,来自Youtube的API视频教程)。可以使用简单但功能强大的领域特定语言(DSL)以API主题问题驱动的方式查询生成的索引和丰富的API社区知识。我们通过Scout-bot展示了我们方法的可行性,Scout-bot是我们用于探索和发现API主题问题的工具。

The huge bandwidth exploited in optical fibers and the ability to handle multiple simultaneous transmissions on the same fiber due to the WDM technology, have made the problem of protection, multicast routing and wavelength allocation (MPRWA) critical for the success of point-to-multipoint applications. In order to maintain the quality of service required by these applications, the network faces the restriction of rapid recovery in cases of failure. Also, it must minimize the different costs that this entails, and prioritize requests in case of not having the necessary resources for recovery. In this context, this work deals with the design of the main multicast route and its protection, with quality of protection (QoP) levels. For this reason, two protection schemes have been addressed: dualtree based and biconnected-subgraph based. To achieve this, competitive evolutionary techniques are applied; where the total number of links used, the number of wavelength converters, the number of splitter nodes, and the number of destinations served and protected are objective functions simultaneously optimized in a Pareto context. The experimental tests were carried out on different network topologies and multicast demands, considering the hypervolume as a Pareto quality measure. The results suggest that the subgraph-based strategy is more promising, obtaining better results than the protection based on dual-tree.
由于波分复用技术(WDM)的存在,光纤的巨大带宽得到了充分利用,并且能够在同一根光纤上同时处理多个传输,这使得保护、组播路由和波长分配(MPRWA)问题成为点对多点应用成功的关键。为了保持这些应用程序所需的服务质量,网络面临着在故障情况下快速恢复的限制。此外,它必须尽量减少由此带来的不同成本,并在没有必要的恢复资源的情况下对请求进行优先排序。在这种情况下,本工作涉及主组播路由及其保护的设计,以及保护质量(QoP)级别。为此,提出了基于双树和基于双连通子图的两种保护方案。为了实现这一目标,应用了竞争性进化技术;其中使用的链路总数,波长转换器的数量,分裂节点的数量以及服务和保护的目的地的数量是在帕累托环境中同时优化的目标函数。将hypervolume作为Pareto质量度量,在不同的网络拓扑和组播需求下进行了实验测试。结果表明,基于子图的保护策略比基于双树的保护策略更有前景,取得了更好的效果。

This work investigated and implemented the integration and effective use of Computer Aided Diagnostic and Detection systems (CAD) with a Picture Archiving and Communication System (PACS) and how this could provide standardized data and expand the coverage of specialized professionals. Likewise, standardized data allowed interoperability between systems. The designed CAD is focused on Diabetic Retinopathy diagnosis with three main functions: (I) digital image processing for detection, segmentation and extraction of retina image anomaly features, (II) binary classification, and finally (III) converter of the results to the DICOM standard (Digital Imagine and Communication Systems). It was decided to use an open source and free license PACS called Orthanc. The results show the successful integration of the systems, since the studies entered in the CAD are accessed directly from the PACS. At the same time, usability tests show a high degree of efficiency, effectiveness and satisfaction of clinical users in the use of the system.

A SIR Epidemiological Model for the Analysis of COVID-19 in Peru 用于分析秘鲁COVID-19的SIR流行病学模型

The purpose of this research work was to analyze the behavior of the pandemic caused by the SARS-CoV-2 virus (COVID-19) in Peru, using the SIR epidemiological model. Using the data, from its inception on March 6, 2020, to June 10, 2020. In our case, in Peru, It has been forecast that the disease will peak, on the contagion curve, at 160-day from the first case. The total duration of the disease is approximately 15 months (450 days), the number of deceases will be approximately 1% of the entire population, and the total number of infected will reach approximately 85% of the population. The evolution of the parameters β, γ and μ show that the disease always tends to disappear, since they are directly related to the population and the condition of the individuals (Susceptible, Infected or Recovered). These parameters control the model, however, it is not trivial to be able to establish adequate values over time, since it will largely depend on the culture of the population mainly, and the policies that the government proposes, and in which way the population will comply with these policies to control the evolution of the pandemic. For example, one way to control the parameter β is compulsory social isolation with a strict epidemiological stratified fence by cities, thereby reducing the value of the contagion rate to zero and allowing the pandemic to be effectively controlled. However, in Peru, this control has not been achieved, since the population is very varied in its culture and quite reluctant to comply with the government's recommendations.
本研究的目的是利用SIR流行病学模型分析秘鲁由SARS-CoV-2病毒(COVID-19)引起的大流行行为。使用数据,从2020年3月6日开始到2020年6月10日。以我们秘鲁的病例为例,据预测,在感染曲线上,该病将在第一例出现后160天达到峰值。该疾病的总持续时间约为15个月(450天),死亡人数约占总人口的1%,感染总人数约占总人口的85%。参数β、γ和μ的演变表明,疾病总是趋于消失,因为它们与群体和个体的状况(易感、感染或恢复)直接相关。这些参数控制着模型,然而,随着时间的推移,能够建立足够的值并不是微不足道的,因为它在很大程度上主要取决于人口的文化,以及政府提出的政策,以及人口将以何种方式遵守这些政策来控制流行病的演变。例如,控制参数β的一种方法是由城市采用严格的流行病学分层围栏进行强制性社会隔离,从而将传染率值降至零,从而使大流行得到有效控制。然而,在秘鲁,这种控制尚未实现,因为人口的文化非常多样化,非常不愿意遵守政府的建议。

Information production has been growing at an accelerated rate. There is a large amount of information to be processed, which makes tasks related to the collection and explotation of text challenging, requiring effort from the most diverse areas, especially computational linguistics. One of the goals of computational linguistics is to enable the collection and explotation of linguistic datasets, through empirical evidence, extracted with the application of computational resources. This work presents the creation of dataset extracted from a newspaper. Techniques were used for extracting sentences, tokenization, named entities recognition (NER), as well as statistical methods for describing the dataset. Other researchers can directly benefit from the available corpus. This work presents a corpus with 1029 annotated news articles in Portuguese for entities according to HAREM categories. In a sample of 108 pages, our experiments show a 97.0% similarity compared to gold standard texts from the same newspaper. For the NER task and automatic annotation of the extracted dataset, proportions of the datasets of Second Harem and aTribuna100 were used to train a hybrid model $text{CRF}+text{LG}$. With the trained model, the 1029 articles extracted were automatically annotated. In general, the values of the metrics demonstrate that optimal metrics achievements for the classification model for the 70/30 Proportion, especially for the Person (PER) category, reaching 91.11% and 95.82% for precision and recall, respectively. Overall, the model showed 95.86% accuracy.
信息生产一直在加速增长。有大量的信息需要处理,这使得与文本的收集和利用相关的任务具有挑战性,需要来自最不同领域的努力,特别是计算语言学。计算语言学的目标之一是通过应用计算资源提取的经验证据,实现语言数据集的收集和利用。这项工作展示了从报纸中提取数据集的创建。技术用于提取句子,标记化,命名实体识别(NER),以及用于描述数据集的统计方法。其他研究人员可以直接从可用的语料库中受益。这项工作提出了一个语料库与1029注释新闻文章在葡萄牙语实体根据HAREM类别。在108页的样本中,我们的实验显示,与同一份报纸的黄金标准文本相比,相似度为97.0%。对于NER任务和提取数据集的自动标注,使用Second Harem和aTribuna100数据集的比例来训练混合模型$text{CRF}+text{LG}$。利用训练好的模型,对提取的1029篇文章进行了自动标注。总的来说,指标的值表明,最优指标实现了70/30比例的分类模型,特别是对于Person (PER)类别,准确率和召回率分别达到了91.11%和95.82%。总体而言,该模型的准确率为95.86%。

This article presents a pilot solution for the automatic insertion of video tracks in Ecuadorian sign language in the multimedia content of Digital Terrestrial Television, in order to reduce the barriers that are inserted for people with hearing disabilities when accessing to information due to their inherent difficulties in dealing with spoken and written languages. Initially, a transport type TS (Transport Stream) with Closed Caption service was generated, based on the standards of the ISDB-Tb digital television standard, established by ARIB (Association of Broadcasting Industries and Businesses). Later an algorithm is specified that allows the extraction of the Closed Caption text and generates the insertion of Ecuadorian sign language video tracks, called LSEC tracks, in the original multimedia content. These video tracks were created by the authors and represent words from the oral language, in Ecuadorian sign language through a 3D-avatar. Finally, a qualitative evaluation was carried out on the accessible content generated by the proposed solution and an analysis of the results obtained is presented.

Research on Optimization Techniques Applied to Precision Agricultural Processes Supported by Technology in Latin America: Opportunities and a Route to Follow 拉丁美洲技术支持下精准农业过程优化技术研究:机遇与路径
Pub Date : 2020-10-01 DOI: 10.1109/CLEI52000.2020.00060

The agricultural sector is facing significant challenges. Producing more food while consuming fewer resources like water, fertilizers, and arable land is probably the most important. Today more than ever, farmers need specialized technological tools to achieve this goal. It is possible to improve agricultural processes by practicing technology-supported precision agriculture. However, more technology development to optimize crop yield is needed worldwide. In this research, we conducted a systematic literature review in which we studied different articles that propose optimization for agricultural processes. We identified some proposals made from multiple researchers at distinct latitudes, focused on optimizing the irrigation and management of pests and diseases. Nevertheless, there are only a few studies that focus on optimizing the crop yield. They do that by controlling the different factors that can affect it. We also found out that only a few studies have been conducted in the Latin American region. Thus, these findings show areas in which there is still a lot of opportunities to contribute to the agro sector in Latin American countries.
农业部门正面临重大挑战。在消耗更少的资源,如水、肥料和可耕地的同时生产更多的食物,这可能是最重要的。今天,农民比以往任何时候都更需要专门的技术工具来实现这一目标。通过实施技术支持的精准农业,可以改善农业生产过程。然而,在世界范围内,需要更多的技术开发来优化作物产量。在这项研究中,我们进行了系统的文献综述,其中我们研究了不同的文章,提出了农业过程的优化。我们确定了来自不同纬度的多位研究人员提出的一些建议,重点是优化灌溉和病虫害管理。然而,专注于优化作物产量的研究很少。他们通过控制可能影响它的不同因素来做到这一点。我们还发现,在拉丁美洲地区只进行了很少的研究。因此,这些调查结果表明,在一些领域仍有很多机会为拉丁美洲国家的农业部门做出贡献。

Producing more food while consuming fewer resources like water, fertilizers, and arable land is probably the most important.

However, more technology development to optimize crop yield is needed worldwide. In this research, we conducted a systematic literature review in which we studied different articles that propose optimization for agricultural processes. We identified some proposals made from multiple researchers at distinct latitudes, focused on optimizing the irrigation and management of pests and diseases. Nevertheless, there are only a few studies that focus on optimizing the crop yield. They do that by controlling the different factors that can affect it.

The administrative area of the Public Ministry of Puno, makes the annual inventory of heritage assets of the institutions located in the different districts of the Region-Puno. The verification of the data, heritage and correlative codes are manual processes; what entails the delay in time and high cost in the inventory process. To improve these drawbacks, we implement a mobile application called “Kusa-Yupaq”, which uses a web server, and the phases of the Mobile-D methodology and Android Studio, Java, Json and XML. PHP, JavaScript, JQuery, Bootstrap, HTML and CSS. Queries and data submission use the REST architecture, and MySQL database manager stores the collected data. The validation of the mobile application was through ISO-9126, 20 people inventoried 200 items in two ways: one using the Kusa-Yupaq application and the other using the traditional way, both were evaluated with the T-Student test. We compare the time and cost of operation between the traditional method and the mobile application. Using Kusa-Yupaq mobile application, the inventory time was reduced by 23% compared to the traditional method; and by using the Kusa-Yupaq mobile application for the inventory process, the operating cost was reduced by 26.2% compared to the traditional method.
普诺公共部的行政区域每年对位于普诺地区不同地区的机构的遗产资产进行清查。数据、遗产和相关代码的验证是人工过程;盘点过程中的时间延迟和高成本是什么?为了改善这些缺点,我们实现了一个名为“kasa - yupaq”的移动应用程序,它使用web服务器、mobile - d方法和Android Studio、Java、Json和XML的各个阶段。PHP, JavaScript, JQuery, Bootstrap, HTML和CSS。查询和数据提交使用REST架构,MySQL数据库管理器存储收集的数据。移动应用程序的验证通过ISO-9126, 20人使用Kusa-Yupaq应用程序和传统方法对200个项目进行了两种方法的盘点,两种方法都使用T-Student检验进行评估。我们比较了传统方法和移动应用程序的操作时间和成本。使用kasa - yupaq移动应用程序,库存时间比传统方法减少23%;通过使用Kusa-Yupaq移动应用程序进行库存流程,与传统方法相比,运营成本降低26.2%。

Literature in Massive Open Online Courses (MOOCs) highlights the importance of students' self-regulation ability for succeed in reaching their learning objectives. The questionnaire is one of the most widely used instruments for measuring self-regulated learning (SRL) strategies in online environments. However, questionnaires available in the literature have some limitations when applied in MOOCs: (1) they do not consider those strategies that have been related with academic achievements in MOOCs; (2) the response rates are low due to their large number of questions, which limits the usage of the collected data; and (3) they do not capture the idiosyncrasies of the actual MOOCs technological environment given that statements of existing questionnaires are based on instruments developed in the 90s. To overcome these shortcomings, this study presents the MOOC-SRL, a questionnaire to measure SRL in MOOCs. This questionnaire is built upon an analysis of existing SRL questionnaires used in traditional face to face, online learning and on a review that analyzed which SRL strategies relate to successful learning outcomes in MOOCs. This questionnaire was validated through an exploratory and confirmatory factor analysis developed over a sample of 4,627 ($N = 4,627$) learners of 6 different MOOCs. The final questionnaire consists of 22 items to assess 5 SRL strategies in MOOCs: Self-efficacy, Goal setting, Study environment management, Organization and Help-seeking.
大规模在线开放课程(MOOCs)的文献强调了学生自我调节能力对成功实现学习目标的重要性。问卷调查是在线环境中自我调节学习策略的最广泛使用的测量工具之一。然而,文献中的问卷调查在mooc中应用时存在一定的局限性:(1)没有考虑那些在mooc中与学术成就相关的策略;(2)问题较多,回复率较低,限制了所收集数据的使用;(3)由于现有问卷的陈述是基于90年代开发的工具,因此它们没有捕捉到实际mooc技术环境的特质。为了克服这些不足,本研究提出了MOOC-SRL,一份测量mooc中SRL的问卷。本问卷是基于对传统面对面在线学习中使用的现有SRL问卷的分析,以及对哪些SRL策略与mooc中成功学习成果相关的综述。通过对6个不同mooc的4,627名(N = 4,627美元)学习者样本进行探索性和验证性因素分析,对该问卷进行了验证。最终问卷共包含22个项目,用于评估mooc的5项自主学习策略:自我效能感、目标设定、学习环境管理、组织和求助。
