专家证据文档识别是专家检索的关键步骤。融合专家候选文档独立页面特征以及页面之间的关联关系,提出了一个专家证据文档识别无向图模型。该方法首先分析各类专家证据文档中的词、URL 链接、专家元数据等独立页面特征以及候选专家证据文档间的链接和内容等关联关系;然后将独立页面特征以及页面之间的关联关系融入到无向图中构建专家证据文档识别无向图模型;最后利用梯度下降方法学习模型中特征的权重,并利用吉布斯采样方法进行专家证据文档识别。通过对比实验验证了该方法的有效性。实验结果表明,该方法有较好的效果。
專傢證據文檔識彆是專傢檢索的關鍵步驟。融閤專傢候選文檔獨立頁麵特徵以及頁麵之間的關聯關繫,提齣瞭一箇專傢證據文檔識彆無嚮圖模型。該方法首先分析各類專傢證據文檔中的詞、URL 鏈接、專傢元數據等獨立頁麵特徵以及候選專傢證據文檔間的鏈接和內容等關聯關繫;然後將獨立頁麵特徵以及頁麵之間的關聯關繫融入到無嚮圖中構建專傢證據文檔識彆無嚮圖模型;最後利用梯度下降方法學習模型中特徵的權重,併利用吉佈斯採樣方法進行專傢證據文檔識彆。通過對比實驗驗證瞭該方法的有效性。實驗結果錶明,該方法有較好的效果。

Expert evidence document recognition is the key step for expert search. Combining specialist candidate document independent page features and correlation among pages, this paper proposes an expert evidence document recognition method based on undirected graph model. First, independent page features such as words, URL links and expert metadata in all kinds of expert evidence document, and correlations such as links and content among candidate expert evidence document are analyzed. Then, independent page features and correlation among pages are integrated into the undirected graph to construct an undirected graph model for expert evidence document recognition. Finally, feature weights are learned in the model by using the gradient descent method and expert evidence document recognition is achieved by utilizing Gibbs Sampling method. The effectiveness of the proposed method is verified by comparison experiment. The experimental results show that the proposed method has a better effect.
