Search engines have become an indispensable tool for obtaining rele-vant information on the Web. The search engine often generates a large number of results, including several irrelevant items that obscure the comprehension of the generated results. Therefore, the search engines need to be enhanced to dis-cover the latent semantics in high-dimensional web data. This paper purports to explain a novel framework, including its implementation and evaluation. To discover the latent semantics in high-dimensional web data, we proposed a framework named Latent Semantic Manifold (LSM). LSM is a mixture model based on the concepts of topology and probability. The framework can find the latent semantics in web data and represent them in homogeneous groups. The framework will be evaluated by experiments. The LSM framework outper-formed compared to other frameworks. In addition, we deployed the framework to develop a tool. The tool was deployed for two years at two places - library and one biomedical engineering laboratory of Taiwan. The tool assisted the re-searchers to do semantic searches of the PubMed database. LSM framework evaluation and deployment suggest that the framework could be used to en-hance the functionalities of currently available search engines by discovering latent semantics in high-dimensional web data.
