2. Website and metadata indexing
● Introduction and definition
● Metadata indexing
● Dublin core elements
● Website indexing process
● Purpose of website and metadata indexing
3. Introduction
● Despite the proliferation of automated search
engines, there are a number of ways in which
human indexers are needed to enhance access
to information on the World Wide Web.
● Website indexes can be similar in style to back of
book indexes or can be designed as hierarchical
pages, which both link directly to the information
required. They complement other navigational
tools such as site maps and search engines.
4. Cont...
● Metadata indexers improve the precision of
access to web documents through search
engines by the use of standard elements similar
to those used in database indexes and library
catalogues.
5. Metadata indexing
● Metadata describes other data. It provides information
about a certain item's content.
● For example, an image may include metadata that
describes how large the picture is, the color depth, the
image resolution, when the image was created, and
other data.
● A text document's metadata may contain information
about how long the document is, who the author is,
when the document was written, and a short summary
of the document.
6. Dublin core elements
● The 15 metadata elements used by Dublin Core are:
● 1.title (the name given the resource),
● 2. creator (the person or organization responsible for the content)
● ,3. subject (the topic covered),
● 4. description (a textual outline of the content),
● 5. publisher (those responsible for making the resource available)
● ,6. contributor (those who added to the content),
● 7.date (when the resource was made available),
● 8. type (a category for the content),
7. Cont...
● 8. type (a category for the content),
● 9. format (how the resource is presented), 10.identifier
(numerical identifier for the content such as a URL),
● 11. source (where the content originally derived from),
● 12. language (in what language the content is written),
● 13. relation (how the content relates to other resources, for
instance, if it is a chapter in a book),
● 14. coverage (where the resource is physically located), and
● 15. rights (a link to a copyright notice).
16. Purpose of website and metadata
indexing
● Encourages efficient retrieval of topics
● Illuminates the author's message with
succinctness
● Groups concepts that are scattered throughout
the text
● Can function as a decisive factor in book
selection or purchase
17. Conclusion
Performance improves significantly when
indexing is used for query processing.
Performance of the indexes depends on the
type of the type of enquiry.
