Different users have different requirements of QoSs (Quality of Services) making them face many problems. The requirement of a special QoS may be a hard requirement or a soft requirement. The hard requirement refers to the QoS which must be satisfied to the user, and the soft one means that the requirement is flexible. This paper tries to solve the service composition problem when there are two kinds of requirements of QoSs. To satisfy various kinds of requirement of the QoS, we propose a composition method based on our proposed framework. We give an analysis from composition models of services and from related QoE (Quality of Experience) of web services. Then, we rank the service candidates and the service requests together. Based on the ranking, a heuristics is proposed for service selection and composition\u2010GLLB (global largest number of service requests first, local best fit service candidate first), which uses \u201clost value\u201d in the scheduling to denote the QoE. Comparisons are used to evaluate our method. Comparisons show that GLLB reduces the value of <jats:italic>NUR<\/jats:italic> (Number of Unfinished service Requests), <jats:italic>FV<\/jats:italic> (Failure Value), and <jats:italic>AFV<\/jats:italic> (Average Failure Value).<\/jats:p>","DOI":"10.1155\/2019\/9871971","type":"journal-article","created":{"date-parts":[[2019,4,7]],"date-time":"2019-04-07T23:31:36Z","timestamp":1554679896000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Location\u2010Aware Web Service Composition Based on the Mixture Rank of Web Services and Web Service Requests"],"prefix":"10.1155","volume":"2019","author":[{"given":"Junwen","family":"Lu","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8980-4950","authenticated-orcid":false,"given":"Guanfeng","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Keshou","family":"Wu","sequence":"additional","affiliation":[]},{"given":"Wenjiang","family":"Qin","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2019,4,7]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2016.01.038"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2012.06.006"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2016.10.047"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2017.04.009"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2014.11.002"},{"key":"e_1_2_11_6_2","doi-asserted-by":"crossref","unstructured":"UpadhyayaB.
