Across different recall values, the weighted Boolean model using fuzzy measures with hybrid terms achieve consistently about 8% higher than those using words. The vector space model using the cosine measures wit

对于那些返回 String、View 或 ModelMap 等类型的处理方法,Spring MVC 也会在内部将它们装配成一个 ModelAndView 对象,该对象包含了视图逻辑名和模型对象的信息。 Spring MVC 借助视图解析器(ViewResolver)得到最终的视图对象(View),这可能是我们常见的 JSP 视图,也可能是一个基于 FreeMarker、Velocity 模板技术的视图...
Let F2n denote the n-dimensional vector space over the prime field F2. Let x = (x1,…,xn) be a vector over F2 of length n. A Boolean function in nvariables is an arbitrary function from F2n to F2. It is called Boolean in honor of the British mathematician and philosopher George ...
Detecting intersections and putting intersecting polygons into groups. You can specify the input models as “solid” (treat the model surface as if it encloses a solid filled space) or “surface” (treat the model surfaces like flat planes). Boolean operations ¶ In the images below, the...
This paper focuses on the studying of information filtering models,and presents three information filtering models that are the Boolean Model,the Vector Space Model and the Latent Semantic Indexing Model. 该文主要是针对信息过滤模型的研究,介绍了布尔模型、向量空间模型和潜在语义索引三种信息过滤模型。 更...
Using this matrix, one can easily find all the documents that contain a given term, and all the terms that are present in a document. In the Boolean model, a document is either relevant or nonrelevant to a query; there is no degree of relevance. The model is based on Boolean logic ...
In this version of the asynchronous updating framework the states of a logical model define a continuous time Markov chain and for a given initial condition the stationary solution is fully defined by the right and left nullspace of the master equation's kinetic matrix. We use topological ...
