Signature-Based Indexing Method

The signature-Based Indexing Approach is a student project developed by J2EE. A variety of algorithms have been suggested for the discovery of data from a large database. However, because the number of patterns generated can be high, choosing which patterns to evaluate can be non-trivial. There is also a need for algorithms and software that can aid in the collection of discovered patterns, such that subsequent research can be carried out in an effective and, preferably, collaborative manner. In this project, we suggest a signature-based indexing approach to simplify the storing and retrieval of relative data from a broad database.

Signature-Based Indexing Method

Project title: Signature-Based Indexing Approach for Effective Content-Based Retrieval of Relative Transient Patterns

Existing Systems:

  • The inverted file indexing methodology concentrates on partial match retrieval, which is subset queries.

  • An inverted array that stores a list of references in the database for all instances of this attribute.

Proposed System:

  • Focuses on supporting content-based data requests from the database.

  • The signature file indexing method can be retrieved efficiently.

Software Requirements:



BACK END: SQL Server 2000

Modules and Description

  • Finding temporal pattern similarity
  • Constructing Signature Files for temporal patterns
  • Answering Content-Based Queries Using the Signature File

Module 1: In this module, we maintain the temporal pattern which are variable-length objects that cannot be represented in a k-dimensional metric space. Each pattern has a list of states. Each pattern has a set of state relationships.

Module 2: Let D be a time pattern database in this module (content-based queries) and let q be a query pattern. The four types of content-based questions sponsored by this study include the following:

  1. Subpattern questions, please. Find the variations in the D that hold the q.
  2. Superpattern’s questions. Find the patterns in D that are the subpatterns of q.
    The topic of equality. Find the patterns in D that are equal to q.
  3. K-the closest subpattern questions. Find the k patterns that are the most similar in D to q.
  4. Super pattern queries are useful when looking for the characteristic sections of a broad pattern, whereas k-nearest subpattern queries to restrict the number of patterns produced by subpattern or super pattern queries. The time pattern is transformed into identical sets.

Module 3:

In this module, the signature file is a bit representation of the query, i.e. the corresponding set is translated to the hash function.

Module 4: In this module, the query is translated to identical sets, and the set is converted to a bit type that is checked for in signature files using BSSF.

A collection of source codes that I wrote in VB 6.0, ASP.NET, PHP, C#.NET, VB.NET and JAVA in a course of my career as web developer and software engineer that I would like to share to my fellow programmers. Some of the codes here is not my original work that I found over the Internet and Books while I'm learning how to program. I hope you find my work useful in your learning in programming. Please share my work to other people also who interested to learn the basics of web development and programming. Thank you very much and Happy Productive Programming Everyone. for more info please WhatsApp us on +91-9481545735 or Email id:
