就赫伯特·乔治·威尔斯（H.G. Well）的小说《世界之战》中某语境中的名词创建图

连接到 OpenLibrary API 来获取小说《世界之战》的文字.

In[1]:=

ol = ServiceConnect["OpenLibrary"]; text = ol["BookText", "BibKeys" -> {{\[ThinSpace]"OLID", "OL7211749M"}\[ThinSpace]}];

我们可以创建一个 WordCloud 来可视化与火星入侵者相关的单词.

In[2]:=

sentences = TextSentences[text[1]]; preresult = DeleteCases[ Function[s, Module[{sentence = DeleteStopwords[TextWords[ToLowerCase[s]]]}, If[MemberQ[sentence, "martian" | "martians"], sentence] ]] /@ sentences, Null]; WordCloud[Tally[preresult]]

Out[2]=

并且就这段内容中的名词创建图.

In[3]:=

edges = Function[u, Module[{words = Pick[u, MemberQ[#, Entity["GrammaticalUnit", "Noun"]] & /@ (PartOfSpeech /@ u), True], basicedges, martianedges}, basicedges = UndirectedEdge @@@ Partition[words, 2, 1]; basicedges ]] /@ preresult; Graph[Flatten[edges], VertexStyle -> RGBColor[0.6, 0.12, 0.], EdgeStyle -> RGBColor[0.84, 0.04, 0.]]

Out[3]=
