A New Approach on Web Content Extraction of Opinion Targets by Using Partially-Supervised Word Alignment Model

Abstract

The important tasks of opinion mining is Mining opinion targets and words from the online reviews. The main component is to detect opinion relations between words. We study a novel approach, which looks for opinion relations in the form of alignment process. After that graph-based algorithm is study. And at the last, a candidate who has higher confidence those are extracted.

As compared with other methods, this model is making the task of opinion relations, for large-span relations also. As Compared with the syntax method, the word alignment model is looks for negative effects of when we are looking for online texts. We can say that this model obtains better precision, As Compared to the traditional unsupervised alignment model. When we search for candidate confidence, we get to know that higher-degree vertices in the graph-based algorithm are decreasing the probability of the generation of error.
