Developing an IR system using latent semantic indexing
Latent semantic indexing can be used for performing categorization with the help of minimum training.
Latent semantic indexing is a technique that can be used for processing text. It can perform the following:
Automatic categorization of text
Conceptual information retrieval
Cross-lingual information retrieval
Latent semantic method may be defined as an information retrieval and indexing method. It makes use of a mathematical technique known as Singular Value Decomposition (SVD). SVD is used for the detection of patterns having a certain relation with the concepts contained in a given unstructured text.
Some of the applications of latent semantic indexing include the following:
Information discovery
Automated document classification text summarization[20] (eDiscovery, Publishing)
Relationship discovery
Automatic generation of the link charts of individuals and organizations
Matching technical papers and grants with reviewers
