Social　Media　Big　Data　(SMBD)　is　widely　used　to　serve　the　economic　and　social　development　of　human　beings.　However,　as　a　young　research　and　practice　field,　the　understanding　of　SMBD　in　academia　is　not　enough　and　needs　to　be　supplemented.　This　paper　took　Web　of　Science　(WoS)　core　collection　as　the　data　source,　and　used　traditional　statistical　methods　and　CiteSpace　software　to　carry　out　the　scientometrics　analysis　of　SMBD,　which　showed　the　research　status,　hotspots　and　trends　in　this　field.　The　results　showed　that:　(1)　More　and　more　attention　has　been　paid　to　SMBD　research　in　academia,　and　the　number　of　journals　published　has　been　increased　in　recent　years,　mainly　in　subjects　such　as　Computer　Science　Engineering　and　Telecommunications.　The　results　were　published　primarily　in　IEEE　Access　Sustainability　and　Future　Generation　Computer　Systems　the　International　Journal　of　eScience　and　so　on;　(2)　In　terms　of　contributions,　China,　the　United　States,　the　United　Kingdom　and　other　countries　(regions)　have　published　the　most　papers　in　SMBD,　high-yield　institutions　also　mainly　from　these　countries　(regions).　There　were　already　some　excellent　teams　in　the　field,　such　as　the　Wanggen　Wan　team　at　Shanghai　University　and　Haoran　Xie　team　from　City　University　of　Hong　Kong;　(3)　we　studied　the　hotspots　of　SMBD　in　recent　years,　and　realized　the　summary　of　the　frontier　of　SMBD　based　on　the　keywords　and　co-citation　literature,　including　the　deep　excavation　and　construction　of　social　media　technology,　the　reflection　and　concerns　about　the　rapid　development　of　social　media,　and　the　role　of　SMBD　in　solving　human　social　development　problems.　These　studies　could　provide　values　and　references　for　SMBD　researchers　to　understand　the　research　status,　hotspots　and　trends　in　this　field.
