The user\u2019s time and location information embedded in wireless network systems can reveal individual and group social relationships, which indirectly reflect each person\u2019s psychological well\u2010being. However, due to challenges in obtaining complete data, the high complexity of related data, and the absence of suitable data analysis models, few studies have analyzed student social behavior using data from university campus networks. This paper employs real\u2010world data from a renowned Chinese university\u2019s wireless campus network for in\u2010depth analysis and introduces a novel multiangle semantic trajectory similarity (MA\u2010STS) algorithm to infer the intimacy and relationship types (such as teacher\u2010student, friends, classmates, or romantic partners) between users. The experiments demonstrate that the proposed algorithm achieves an accuracy of over 95%.<\/jats:p>","DOI":"10.1155\/2023\/9927800","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T01:20:07Z","timestamp":1686878407000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["MA\u2010STS\u2010Based Social Intimacy Analysis Algorithm Using Real Campus Network Data"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2966-2521","authenticated-orcid":false,"given":"Yifu","family":"Zeng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangshu","family":"Qi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiping","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiatao","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nian","family":"Pan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6069-6869","authenticated-orcid":false,"given":"Guo","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,6,15]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-004-4750-0"},{"key":"e_1_2_11_2_2","unstructured":"KimM.andKotzD.
