The automated composition of services to a target software artifact has been tackled with many AI techniques, but existing approaches make unreasonably strong assumptions such as a predefined data flow, are limited to tiny problem sizes, ignore non-functional properties, or assume offline service repositories. This paper presents an algorithm that automatically composes services without making such assumptions. We employ a backward search algorithm that starts from an empty composition and prepends service calls to already discovered candidates until a solution is found. Available services are determined during the search process. We implemented our algorithm, performed an experimental evaluation, and compared it to other approaches."}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"10","name":"SFB 901 - Subprojekt B2"},{"name":"SFB 901 - Project Area B","_id":"3"}],"file":[{"success":1,"date_updated":"2018-03-20T07:42:03Z","relation":"main_file","access_level":"closed","content_type":"application/pdf","file_id":"1434","date_created":"2018-03-20T07:42:03Z","creator":"florida","file_name":"319-07207336.pdf","file_size":345742}],"title":"Automated Online Service Composition","user_id":"477","status":"public","language":[{"iso":"eng"}],"year":"2015","date_created":"2017-10-17T12:41:54Z","date_updated":"2022-01-06T06:59:04Z","_id":"319","file_date_updated":"2018-03-20T07:42:03Z","author":[{"full_name":"Mohr, Felix","first_name":"Felix","last_name":"Mohr"},{"full_name":"Jungmann, Alexander","first_name":"Alexander","last_name":"Jungmann"},{"first_name":"Hans","full_name":"Kleine Büning, Hans","last_name":"Kleine Büning"}],"department":[{"_id":"355"}],"citation":{"mla":"Mohr, Felix, et al. “Automated Online Service Composition.” <i>Proceedings of the 12th IEEE International Conference on Services Computing (SCC)</i>, 2015, pp. 57--64, doi:<a href=\"https://doi.org/10.1109/SCC.2015.18\">10.1109/SCC.2015.18</a>.","bibtex":"@inproceedings{Mohr_Jungmann_Kleine Büning_2015, title={Automated Online Service Composition}, DOI={<a href=\"https://doi.org/10.1109/SCC.2015.18\">10.1109/SCC.2015.18</a>}, booktitle={Proceedings of the 12th IEEE International Conference on Services Computing (SCC)}, author={Mohr, Felix and Jungmann, Alexander and Kleine Büning, Hans}, year={2015}, pages={57--64} }","short":"F.

The player's utility is at most the sum of these demands, provided they are fully satisfied. Every resource has a limited capacity and if it is exceeded by the total demand, it has to be split between the players. Since these games generally do not have pure Nash equilibria, we consider approximate pure Nash equilibria, in which no player can improve her utility by more than some fixed factor $\\alpha$ through unilateral strategy changes. There is a threshold $\\alpha_\\delta$ (where $\\delta$ is a parameter that limits the demand of each player on a specific resource) such that $\\alpha$-approximate pure Nash equilibria always exist for $\\alpha \\geq \\alpha_\\delta$, but not for $\\alpha < \\alpha_\\delta$. We give both upper and lower bounds on this threshold $\\alpha_\\delta$ and show that the corresponding decision problem is ${\\sf NP}$-hard. We also show that the $\\alpha$-approximate price of anarchy for BAGs is $\\alpha+1$. For a restricted version of the game, where demands of players only differ slightly from each other (e.g. symmetric games), we show that approximate Nash equilibria can be reached (and thus also be computed) in polynomial time using the best-response dynamic. Finally, we show that a broader class of utility-maximization games (which includes BAGs) converges quickly towards states whose social welfare is close to the optimum.","lang":"eng"}],"page":"178-189","ddc":["040"],"publication":"Proceedings of the 8th International Symposium on Algorithmic Game Theory (SAGT)","type":"conference","citation":{"short":"M.

Each agent aims for a central position at minimum cost for creating edges. In particular, the general model (Fabrikant et al., PODC'03) became popular for studying the structure of the Internet or social networks. Despite its significance, locality in this game was first studied only recently (Bilò et al., SPAA'14), where a worst case locality model was presented, which came with a high efficiency loss in terms of quality of equilibria. Our main contribution is a new and more optimistic view on locality: agents are limited in their knowledge and actions to their local view ranges, but can probe different strategies and finally choose the best. We study the influence of our locality notion on the hardness of computing best responses, convergence to equilibria, and quality of equilibria. Moreover, we compare the strength of local versus non-local strategy changes. Our results address the gap between the original model and the worst case locality variant. On the bright side, our efficiency results are in line with observations from the original model, yet we have a non-constant lower bound on the Price of Anarchy."}],"doi":"10.1007/978-3-662-48054-0_21","has_accepted_license":"1","title":"Network Creation Games: Think Global - Act Local","file":[{"file_id":"1472","content_type":"application/pdf","access_level":"closed","date_created":"2018-03-21T09:27:12Z","creator":"florida","file_size":279995,"file_name":"275-978-3-662-48054-0_21.pdf","success":1,"date_updated":"2018-03-21T09:27:12Z","relation":"main_file"}],"user_id":"477","year":"2015","language":[{"iso":"eng"}],"status":"public","date_created":"2017-10-17T12:41:45Z","date_updated":"2022-01-06T06:57:40Z","_id":"275","file_date_updated":"2018-03-21T09:27:12Z","author":[{"last_name":"Cord-Landwehr","full_name":"Cord-Landwehr, Andreas","first_name":"Andreas"},{"last_name":"Lenzner","full_name":"Lenzner, Pascal","first_name":"Pascal"}],"department":[{"_id":"63"}],"series_title":"LNCS","citation":{"ama":"Cord-Landwehr A, Lenzner P.

However, this combination and configuration is a manual procedure and has to be repeated for different consumers' or market requirements regarding matching quality. In this paper, we propose our framework MatchBox, which supports a broker in reusing existing matching approaches and combining them in a model-driven way based on a reconfigurable model of the matching process.Using this reconfigurable model, MatchBox takes care of control and data flow between matching approaches and executes the modeled processes automatically.As a case study, we integrated eleven matchers into MatchBox to demonstrate that it remains flexibility and reduces effort for a broker at the same time.","lang":"eng"}],"doi":"10.1145/2737166.2737174","project":[{"name":"SFB 901","_id":"1"},{"_id":"3","name":"SFB 901 - Project Area B"},{"_id":"9","name":"SFB 901 - Subproject B1"}],"file":[{"creator":"florida","file_size":2090964,"file_name":"279-p75-platenius.pdf","file_id":"1471","content_type":"application/pdf","access_level":"closed","date_created":"2018-03-21T09:26:40Z","relation":"main_file","date_updated":"2018-03-21T09:26:40Z","success":1}],"title":"MatchBox: A Framework for Dynamic Configuration of Service Matching Processes","page":"75-84","type":"conference","publication":"Proceedings of the 18th International ACM Sigsoft Symposium on Component-Based Software Engineering (CBSE'15)","ddc":["040"]},{"page":"18-20","volume":48,"issue":"7","publication":"IEEE Computer","ddc":["000"],"type":"journal_article","user_id":"16153","keyword":["self-awareness","self-expression"],"title":"Self-Aware and Self-Expressive Systems – Guest Editor's Introduction","file":[{"file_size":5605009,"file_name":"07163237.pdf","creator":"ups","date_created":"2018-11-02T15:47:45Z","file_id":"5313","access_level":"closed","content_type":"application/pdf","relation":"main_file","date_updated":"2018-11-02T15:47:45Z","success":1}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"},{"_id":"14","name":"SFB 901 - Subproject C2"},{"grant_number":"610996","_id":"34","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures"}],"has_accepted_license":"1","doi":"10.1109/MC.2015.205","file_date_updated":"2018-11-02T15:47:45Z","_id":"1772","date_updated":"2022-01-06T06:53:19Z","date_created":"2018-03-23T14:06:12Z","publisher":"IEEE Computer Society","year":"2015","language":[{"iso":"eng"}],"status":"public","citation":{"ama":"Torresen J, Plessl C, Yao X.

Our corpus is based on the entire revision history of Wikidata, the knowledge base underlying Wikipedia. Among Wikidata's 24 million manual revisions, we have identified more than 100,000 cases of vandalism. An in-depth corpus analysis lays the groundwork for research and development on automatic vandalism detection in public knowledge bases. Our analysis shows that 58% of the vandalism revisions can be found in the textual portions of Wikidata, and the remainder in structural content, e.g., subject-predicate-object triples. Moreover, we find that some vandals also target Wikidata content whose manipulation may impact content displayed on Wikipedia, revealing potential vulnerabilities. Given today's importance of knowledge bases for information systems, this shows that public knowledge bases must be used with caution."}],"project":[{"name":"SFB 901","_id":"1"},{"_id":"17","name":"SFB 901 - Subprojekt C5"},{"name":"SFB 901 - Project Area C","_id":"4"}],"page":"831--834","publication":"Proceedings of the 38th International ACM Conference on Research and Development in Information Retrieval (SIGIR 15)","ddc":["040"],"type":"conference"},{"status":"public","year":"2015","date_created":"2017-10-17T12:41:38Z","date_updated":"2022-01-06T06:56:05Z","_id":"240","file_date_updated":"2018-03-21T10:28:50Z","author":[{"first_name":"Shouwei","full_name":"Li, Shouwei","last_name":"Li"},{"last_name":"Mäcker","id":"13536","first_name":"Alexander","full_name":"Mäcker, Alexander"},{"last_name":"Markarian","id":"37612","full_name":"Markarian, Christine","first_name":"Christine"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"},{"last_name":"Riechers","full_name":"Riechers, Sören","first_name":"Sören"}],"department":[{"_id":"63"}],"series_title":"Lecture Notes in Computer Science","citation":{"apa":"Li, S., Mäcker, A., Markarian, C., Meyer auf der Heide, F., &#38; Riechers, S.

We introduce a new model for these problems such that a resource can be leased for K different durations each incurring a different cost (longer leases cost less per time unit). Each demand i can be served anytime between its arrival ai and its deadline ai+di by a leased resource. The objective is to meet all deadlines while minimizing the total leasing costs. This model is a natural generalization of Meyerson’s ParkingPermitProblem (FOCS 2005) in which di=0 for all i. We propose an online algorithm that is Θ(K+dmaxlmin)-competitive where dmax and lmin denote the largest di and the shortest available lease length, respectively. We also extend the SetCoverLeasing problem by deadlines and give a competitive online algorithm which also improves on existing solutions for the original SetCoverLeasing problem."}],"project":[{"name":"SFB 901","_id":"1"},{"_id":"16","name":"SFB 901 - Subprojekt C4"},{"_id":"5","name":"SFB 901 - Subprojekt A1"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"4","name":"SFB 901 - Project Area C"}],"file":[{"relation":"main_file","date_updated":"2018-03-21T10:28:50Z","success":1,"creator":"florida","file_name":"240-chp_3A10.1007_2F978-3-319-21398-9_22.pdf","file_size":264482,"file_id":"1498","content_type":"application/pdf","access_level":"closed","date_created":"2018-03-21T10:28:50Z"}],"title":"Towards Flexible Demands in Online Leasing Problems","user_id":"15504"},{"date_updated":"2022-01-06T06:53:25Z","_id":"18003","type":"bachelorsthesis","year":"2015","language":[{"iso":"eng"}],"status":"public","date_created":"2020-08-17T08:18:04Z","publisher":"Universität Paderborn","department":[{"_id":"79"}],"citation":{"apa":"Götte, T.
