词消歧算法(Lesk算法) [英] word disambiguation algorithm (Lesk algorithm)
问题描述
许志国.. 任何人可以帮助我找到一个算法的Java code查找基于上下文搜索词的同义词,我要实现的算法WordNet的数据库。
Hii.. Can anybody help me to find an algorithm in Java code to find synonyms of a search word based on the context and I want to implement the algorithm with WordNet database.
例如,我运行一个Java程序。从上下文,我想找到的同义词跑这个词,但同义词必须根据上下文是合适的。
For example, "I am running a Java program". From the context, I want to find the synonyms for the word "running", but the synonyms must be suitable according to a context.
推荐答案
让我来举例说明一个可能的方法:
Let me illustrate a possible approach:
- 让你的句子是
A B C
- 让每一个字都同义词集即
{A:(A1,A2,A3),B:(B1),C(C1,C2)}
李> - 现在,形成可能的同义词集合集:
(A1,B1,C1),(A1,B1,C2),(A2,B1,C1)...(A3,B1,C2)
- 定义功能
F(A,B,C)
返回之间的距离(分值)(A,B,C)。 - 在调用F每个同义词集合集。
- 选择设定的最高得分。
- Let your sentence be
A B C
- Let each word have synsets i.e.
{A:(a1, a2, a3), B:(b1), C:(c1, c2)}
- Now form possible synset sets:
(a1, b1, c1), (a1, b1, c2), (a2, b1, c1) ... (a3, b1, c2)
- Define function
F(a, b, c)
which returns the distance (score) between (a, b, c). - Call F on each synset set.
- Pick the set with the maximum score.
对于初学者来说,函数F可以只返回节点的两个节点之间的数的倒数的乘积:
For starters, the function F can just return the product of the inverse of the number of nodes between the two nodes:
最大化(产品[i = 0到的len(句子); J = 0到的len(句子)](1 / D(node_i,node_j)))
Maximize(Product[i=0 to len(sentence); j=0 to len(sentence)] (1/D(node_i, node_j)))
之后,你可以增加其复杂性。
Later on, you can increase its complexity.
