3.生成云词

)
# 从单词和频率创建词云

# wc.generate(txt)
# 保存图片

4.生成人物关系图
# 生成人物关系图

# 人物节点颜色
colors = color_list()

relations = {}
# 按段落划分,假设在同一段落中出现的人物具有共现关系

maxRela = max([v for k, v in relations.items()])
relations = {k: v / maxRela for k, v in relations.items()}
# return relations
plt.figure(figsize=(15, 15))
# 创建无多重边无向图
G = nx.Graph()
for k, v in relations.items():
G.add_edge(k[0], k[1], weight=v)
# 筛选权重大于0.6的边
elarge = [(u, v) for (u, v, d) in G.edges(data=True) if d['weight'] > 0.6]
# 筛选权重大于0.3小于0.6的边
emidle = [(u, v) for (u, v, d) in G.edges(data=True) if (d['weight'] > 0.3) & (d['weight'] <= 0.6)]
# 筛选权重小于0.3的边
esmall = [(u, v) for (u, v, d) in G.edges(data=True) if d['weight'] <= 0.3]
# 设置图形布局
pos = nx.spring_layout(G) # 用Fruchterman-Reingold算法排列节点(样子类似多中心放射状)
# 设置节点样式
nx.draw_networkx_nodes(G, pos, alpha=0.8, node_size=1300, node_color=colors)
# 设置大于0.6的边的样式
nx.draw_networkx_edges(G, pos, edgelist=elarge, width=2.5, alpha=0.9, edge_color='g')
# 0.3~0.6
nx.draw_networkx_edges(G, pos, edgelist=emidle, width=1.5, alpha=0.6, edge_color='y')
# <0.3
nx.draw_networkx_edges(G, pos, edgelist=esmall, width=1, alpha=0.4, edge_color='b', style='dashed')
nx.draw_networkx_labels(G, pos, font_size=14)
plt.title("《三国演义》主要人物社交关系网络图")
# 关闭坐标轴

3.运行结果截图
1.统计词频词性并写入文件中
2.可视化人物出现次数
3.生成云词
4.生成人物关系图
