Citation index
Definition
- A citation is the textual form in which a document refers to another document. A proper publication features a references section: each entry in this section is a citation. Citation indexing consists into the indexing of the text of each such entry. (SMEAL, retrieved, 17:17, 15 September 2006 (MEST))
Technology
It is very important that teachers (or some other facilitators) explain how such an engine works and/or to engage learners in a formal activity that makes them learn. Most people (including university students) do not take enough time to understand how such specialized engines work.
CiteSeer and Smeal
CiteSeer is both a citation engine and a digital library
CiteSeer is based on the SmealSearch engine. The citation engine offers the following main functionalities:
- Search citations with different query terms (e.g. an author name).
- The result will show references with author, title, date, journal/volume etc.
- Details for each result can be consulted in the context page.
The digital library engine allows
- to search the documents database with keywords.
- The sortable results include a title, a link, a context for the search keywords, number of citations, etc.
CiteSeer also integrates with other sources of metadata such as the [ http://portal.acm.org/ ACM Portal]'s Guide to computing literature and provides [Open archive metadata in turn.
CiteSeer is a service that continously improves and adds new functionalities. For details see: SMEALSearch Help Page and the FAQ
ACM Portal
The Guide to computing literature allows to search publications. Each entry found will display:
- Authors (with links)
- Collaborative colleages (people an author with whom other articles have been published. Note: this is approximative since it will show articles from authors who have the same name.
- A link to similar articles (this is very useful)
The ACM digital library (indexing its own publications) adds:
- Citings (who has cited this article)
- What articles have been consulted by other people who consulted this article (peer-to-peer reading, see social navigation).
- A hierarchical tree of index terms
- Design terms
- Keywords
