These word matching techniques have constantly relied on matching query terms with document

  • Description Of The Thesis : Web Based Document

    2552 Words  | 11 Pages

    OVERVIEW OF THE THESIS Web based document (WBD) commonly known as Latent Semantic Indexing in the context of information retrieval is a fully automatic mathematical/statistical technique for extracting and inferring relations of expected contextual usage of words in passages of discourse. It is based on the application of a particular mathematical technique, called Singular Value Decomposition (SVD), to a word-by-document matrix [4]. The word-by-document matrix is formed from WBD inputs that consist

    clustering. 3.1 Bisecting K-means The Bisecting K-means is based on K-means and can be run quickly for a big volume of data that have large dimensions. Thus it is appropriate for text clustering (Steinbach et al., 2000). At the beginning, all of the documents are in one partition. Then the following procedure will be repeated K 1 times to obtain K clusters. Initially the partition to be broken is selected. In the standard algorithm the partition with maximal cardinality is chosen, but in this research

    It is like a database where crawler searches the documents and put into it. It is used to store the data which is search by the crawler. It provides the documents as a input to the clustering algorithm to make the cluster. 5.5.2 Clustering This phase take the input of documents to make the cluster. To make the cluster I have applied an agglomerative approach which is a hierarchal approach. It take 2 document and make one cluster and produce the hierarchy. With this hierarchy approach

    RESPONSBILITY MATRIX What is the Responsibility matrix and what is its purpose? When planning a project it is necessary to assign the work on the project to the project team so that there will be one person responsible for each part of the project and it is clear who performs the work, with whom it should be consulted, and who is to be informed of this activity. The responsibility matrix is a tool used to define the powers of individual project team members for various parts of project works (work

    contexts and that related texts will be composed of similar words. This creates a co-occurrence matrix where each row represents a distinct term and each column a distinct document. The cells of the matrix are populated with frequency counts where each cell shows a count of the number of times the term of the corresponding row occurred in the document of the corresponding column. With large amount of terms appearing in a typical corpus, there is a high tendency of having large dimensional vectors with

    Mining Unstructured Text to Build e-democracy Background In today's day and age, internet and wireless technologies are increasingly able to provide a way for citizens to engage in political discussions, which is much more involved than in traditional democracy and government action. As such, in this technological realm, the government is able to enter unstructured data into these citizen-created dialogues, which has begun to pave the way to mainly e-democracy and also m-democracy. In viewing
