In creating a user profile, how to extract collections of metadata of documents is a significant point. Although the efficiency of the structures such as keyword-based has proven, there is not research on key phrase based user profiles in the process of personalization. Previous methods to create user profiles emphasize keyword extraction while ignoring the existence of key phrases in the documents. This article proposes the use of keyphrase-based user profiles in personalized web search. We investigate the state of the art keyphrase extraction algorithms by considering different models of supervised and unsupervised methods. This can overcome the problems of missing keyphrases in user profiles and increase the accuracy of information retrieval. Finally, we evaluate keyphrase-based user profiles using a re-ranking algorithm to complete the process of personalization using different datasets. Personalized models based on supervised keyphrase extraction approaches obtained more accuracy by 7% than unsupervised approaches.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187440","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}

This paper presents a catalogue of analytical software widely used for contextual knowledge explication and scientific text mining. The catalogue focuses on the contextual knowledge types (contexts) processed with a software considered, and applies both, human-oriented and machine-oriented IS descriptions. The human-oriented description of a software catalogue is presented by a corresponding IS architecture (applications and data) on conceptualization level. The machine-oriented software description is performed with Dublin Core metadata. The Dublin Core metadata have allowed structuring the main software characteristics and provided the metadata export to other presentation formats to be place in various kinds of ISs and metadata aggregators. The machine-readable part of the catalogue performs the replenishment tasks, software effective search and its recognition in accordance with the research tasks. The practical implementation of the catalogue as an open access network platform by the OAI-PMH metadata exchange protocol provides the integration into the scientific information space as a researchers’ guidance. the authors, types of contexts are distinguished as an essential software characteristics. The main functions implemented in the software are also allocated as a separate characteristics. The following is a structured description of a software to be presented in a catalogue form. Software systematization in the catalogue is performed on the enlarged classes of tasks. The catalogue is presented in two forms: human-readable and machine-readable. A human-readable catalogue representation proposes a software architecture at a conceptual level. The software architecture reflects the modules, functions, and types of contexts being processed. The paper presents two cases to demonstrate the results obtained in the form of a structured description of T-Libla and Voyant-tools softwires. The developed systematized and structured presentation of the software replenishes the catalogue with new software, as well as ensures its effective selection for research purposes based on contextual knowledge explication and analysis.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126179664","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}

The environment supports two main processes taking place during the collective effort on a complex problem: process organization (planning the activities and the distribution of the responsibilities) and building a solution (plan implementation). To address the problem of human-machine interoperability, the environment leverages multi-aspect ontologies, allowing to represent the status of the process and information about the problem in a human- and machine-readable way. The proposed solution can be employed in building interoperable human-machine collaborative systems in variety of complex problem domains.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128366821","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}

Instead of measuring the relevance of the entire text for a search query, the focus of our approach of fact retrieval and text mining is on spotting only essential parts of text. We propose to enrich search queries by aspects supporting highly precise retrieval. An aspect denotes the unique interpretation of a set of words that appear in close proximity. We conceive an aspect representation as a hierarchical structure composed by its semantic elements that, in turn, constitute the aspect’s implicit meaning. In this paper, we present the definition and application of aspect blueprints that serve as standardized representations of aspects. Our prototypical system Contexter operates on these blueprints and locates facts in texts. In a semi-automatic way, the system tries to detect variants of blueprints that the user can confirm or reject. Here, we illustrate our approach and system in the realm of economic information.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115631783","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}

For instance, 95.5% of Brazilian software development companies are micro or small. Although cloud computing plays a key role in reducing infrastructure and personnel costs in small companies, little is known on the state of cloud adoption in micro & small Brazilian IT companies (MSBCs). If cloud adoption in MSBCs differs significantly from other companies around the world, MSBCs may need tailored training and tools. Moreover, these differences may limit MSBCs competitiveness in the global IT market. To understand the state of cloud adoption in MSBCs, we partnered with a regional IT association to conduct a survey with their 93 associated companies, from which we received 29 valid responses (31% response rate). Eighty-three percent of surveyed companies are currently using cloud, 65% of cloud users in our survey use more than one cloud provider, and 54% of current cloud users reported issues when using cloud services. Compared to related surveys, we did not find significant differences regarding perceptions and practices of cloud adoption. This result suggests that cloud adoption may not vary significantly with company size and region.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127007769","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}

When using a combination of server monitoring with ping and network connection check with Ethernet OAM, the system sets higher priorities to the port connected to a long running server, and the port within a certain time after the connection change or virtual machine addition is set. The system then selects the ports from the higher priority port to be monitored by Ethernet OAM. As a result of the evaluation by the simulation, by dynamically selecting the port to be monitored for Ethernet OAM using the proposed method, it was confirmed that the average locating time of the VM failure is reduced by 2.2% compared to the conventional method. In the data center for cloud services running many VMs, it is possible to shorten the recovery from VM failure while suppressing the number of objects monitored by Ethernet OAM by using this method.","PeriodicalId":254527,"journal":{"name":"Proceedings of the 19th International Conference on WWW/Internet","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128543769","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}
