PaaS-BDP (Platform-as-a-Service for Big Data) is an architectural pattern based on resource pooling and the use of a unified programming model for building big data processing pipelines capable of processing both batch and stream data. It uses container cluster technology on a PaaS service model to overcome common shortfalls of current big data solutions offered by major cloud providers such as low portability, lack of interoperability and the risk of vendor lock-in.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128495193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is important to evaluate their complexity to promote their sharing and reuse in the biomedical domain. This study analyses and discusses the advanced complexity features of the biomedical ontologies stored in the BioPortal repository. A set of 100 biomedical ontologies from the BioPortal repository was collected. Thereafter, the collected ontologies are assigned to the analysis process to compute their advanced complexity metrics including the: size of the vocabulary, entropy of ontology graphs, the average number of paths per class, the tree impurity, class richness, percentage of part-of relations in the total number of relations, and many more. The results show that the biomedical ontologies studied are highly complex; this finding is evidenced by the analysis of their size of the vocabulary, average number of paths and entropy of ontology graph. However, it was interesting to learn that the structure of these ontologies favour their easy reuse and maintenance; these findings were reached through the analysis of the tree impurity, class and relationship richness of these ontologies.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129779342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Theoretical Basis of Language System with State Constraints","authors":"S. Yamasaki","doi":"10.5220/0009385100800087","DOIUrl":"https://doi.org/10.5220/0009385100800087","url":null,"abstract":": This paper presents theoretical basis of a language system whose program is described as algebraic expressions and implemented as abstract state machine. The behaviors of the described expressions may be captured (with their models) as causing sequences for state transitions, where composition and alternation for state transitions are mechanized in algebraic structure. Monitoring facilities to the language system may be described with state concepts, as well. With respect to intuitionistic logic and logical program containing negatives, Heyting algebra expressions are taken rather than already established nonmonotonic reasoning programs with negations, where 3-valued domain may be of use for the undefined to be allowable such that positives and negatives may be consistently evaluated, instead of rigid 2-valued settlements. We may have a standard form of Heyting algebra expressions in accordance to logical and AI programming, where the expressions are constrained with states. The states may be regarded as environmental conditions or objects as in object-oriented programming. As regards 3-valued models of given expressions, monotonic mapping cannot be in general as-sociated with, but some ways are presented to approximate fixed points of a mapping for the given expression. Then the formal description of programs may be given with reference to state transitions, which is thought of as proposing a language system structure.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116772316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, social media play an important role in human information seeking behavior during and shortly after crisis events. Moreover, automated accounts (so called social bots) have been identified to play an instrumental role in manipulating the public discourse on social media. In this paper, we investigate the impact of bot accounts on the Twitter discourse surrounding the terror attack that took place in Vienna, Austria, on November 2 nd 2020. The corresponding data-set consists of 399,247 tweets. In our analysis, we derive a structural topic model and map it to the five “narratives of crisis” as proposed by Seeger and Sellnow. Among other things, we were able to identify bot activity in neutral as well as in negative narratives, including breaking news updates, finger pointing, and expressions of shock and grief. Positive narratives, such as stories of heroes, were predominantly driven by human users. In addition, we found that the bots contributing to narratives surrounding the Vienna terror attack did not have the ability of picking up local story lines and contributed to more global narratives instead. Moreover, we identified similar temporal patterns in narratives with high bot involvement.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125160593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the controversies surrounding police operations during violent protests, our analysis especially focuses on emotions conveyed in messages related to the local police. We found that a) negative emotions of high arousal (anger and fear) dominate in messages mentioning the police on all three social networks, b) emotional content was forwarded (retweeted) more often, regardless of the corresponding emotion valence, and c) in contrast to previous studies we found that emotions have a considerably larger impact on the retweeting behavior than the number of hashtags a message contains.","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125540083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Witten","doi":"10.5220/0005855901430154","DOIUrl":"https://doi.org/10.5220/0005855901430154","url":null,"abstract":"In this paper we extend the previous work of Witten and her team on defining a classical physics driven model of survival in aging populations (Eakin, 1994; Eakin and Witten, 1995a; Eakin and Witten, 1995b; Witten and Eakin, 1997) by revisiting the concept of a force of aging and introducing the concepts of a momentum of aging, a kinetic energy and a potential energy of an aging. As an example of the use of these constructs, we then explore the implications of these concepts with respect to the (Yu et al., 1982) diet restriction experiments. 1 HISTORY OF RELIABILITY The history of the demographics of aging is tightly bound to the field of survival analysis (Witten, 1981; Elandt-Johnson and Johnson, 1999). Survival analysis, however, emerged from the earlier discipline of reliability theory (Abdel-Hameed et al., 1984; Ansell and Phillips, 1994). The constructs of reliability theory emerged from the 1950’s gedankt experiments of the computer scientist John Von Neumann. His interest (Neumann, 1956) was in how one would go about building a reliable biological organism out of unreliable parts. Until the thought experiments of von Neumann, the concept of reliability had not been well-defined. Von Neumann’s argument proceeded as follows. He began by defining the concept of the conditional instantaneous failure rate, denoted by λ(t). We interpret this as follows. The condition is that the failure has not occurred at time t given that the organism has survived until time t. With this in mind, we may then define the reliability R(t) of an organism as the probability of no failure of the organism before time t. If we let f (t) be the time to (first) failure (this is the same as the failure density function), then the reliability R(t) is given by R(t) = 1−F(t) where F(t) = ∫ t 0 f (τ)dτ ((Abdel-Hameed et al., 1984; Deshpande and Purohit, 2005; Elandt-Johnson and Johnson, 1999; Kalbfleish and Prentice, 2002; Lawless, 2003)). How do we actually obtain an equation for the reliability R(t)? We do this as follows. Suppose we ask what is the reliability R(t +∆t) where ∆t is a small time increment. In other words, suppose that we know the reliability of the organism at time t and we want to know the organism’s reliability at a small time increment ∆t later than time t. In order for the organism to be operational at time t+∆t, the organism must have been operational until at least time t and then not have failed in the time interval (t, t +∆t). We can express this mathematically as follows. The reliability R(t +∆t) is given by R(t +∆t) = R(t)−λ(t)R(t)∆t (1) Reading equation [1], we see that to be functional (operational) at time t+∆t, the organisms had to be functional at time t (denoted by the reliability term R(t) on the right hand side of the equation). Next, we have to subtract out all of the items that failed in the time interval (t, t +∆t) (given by the second term on the right hand side of equation [1]). What remains after this subtraction is all of the organ","PeriodicalId":414016,"journal":{"name":"International Conference on Complex Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
