| 摘要: |
| 文本和用户查询用属性坐标表示,以交点与查询重心点的距离确定为文本与查询间的相似度进行计算,利用相关性反馈技术调整检索策略,得到一个基于属性坐标的文本信息检索模型.实验表明,该模型的检索方法可行,检索效果较好. |

| Abstract: |
| A kind of text information retrieval model based on attribute coordinates is presented.In this model,the texts and the queries are represented using attribute coordinates.The distance of the point of intersection to the barycenter of query is represented as the similarity between the text and the query,and be calculated.With the use of the relevant feedbacks,the retrieval tactichas been changed.The efficient of information retrieval is improved. |
| Key words: text information retrieval attribute coordinate similarity relevance feedback |
