Abstract	本发明公开了一种搜索关键词获取的方法。该方法包括：统计目标领域的特定相关关键词和特定无关关键词；将获取的待分析文本进行分词得到候选关键词；将每个所述候选关键词与所述特定无关关键词进行匹配；若每个所述候选关键词均匹配失败，则计算每个所述候选关键词的词向量与所述目标领域的每个特定相关关键词的词向量的相似度；若所述相似度大于预设阈值，则将该目标领域的特定相关关键词作为待分析文本的关键词输出。本发明提供的方法可实现根据用户输入的待分析文本比较准确地输出与用户的某一兴趣或需求相关的关键词，并将与候选关键词语义相似度较高的该目标领域的特定相关关键词作为待分析文本的关键词输出，丰富用户的搜索关键词。
Other Abstract	The invention discloses a method for acquiring search keywords. The method includes: making statistics about specific relevant keywords and specific irrelevant keywords in a target domain; performing word segmentation on to-be-analyzed texts acquired to acquire candidate keywords; matching the candidate keywords with the specific irrelevant keywords; if the candidate keywords fail in matching, calculating similarity of word vectors of the candidate relevant keywords and word vectors of the specific relevant keywords in the target domain; if the similarity is greater than a preset threshold, outputting the specific relevant keywords in the target domain as the keywords of the to-be-analyzed tests. With the method, the keywords relevant to certain interests or requirements of users can be accurately output according to the to-be-analyzed tests input by the users can be realized, the specific relevant keywords in the target domain, higher in similarity with the candidate keywords are output as the keywords of the to-be-analyzed tests, and the search keywords are enriched for the users.
