When starting a work in a new research topic or brainstorming for novel ideas, a researcher have to be well aware of most recent improvement in the topic.
Search for related work is an important part of writing papers Substantial effort is wasted in rediscover ideas

When papers are written, many times the author wants to make some citations at a place but he is not sure which papers to cite.
the number of research paper published is exponentially growing.
This filtering process is generally tedious and time consuming.

Two common ways to find reference papers are:
1. search documents on search engines such as Google.
2. trace the cited references by starting with a small number of initial papers (seed-papers).

We wish to have a recommendation system which can recommend Citations for papers.
the user has already written a few pages about the topic, and is able to submit this document to the search system as the query.
the user wants documents that the query document might cite.

recommender systems emerged as an independent research area in the mid-1990s
Examples of such applications include recommending books, CDs, and other products at Amazon.com, movies by MovieLens and so on

recommend items based on the contents of the items a user has experienced before.
Text-based Analysis These approaches use NLP and text mining
methods to find papers that are semantically similar to the input paper

1. candidate set :1. the system retrieves the top 100 most similar papers
to the query document and adds them to R (base set).2. all papers cited by any paper in R are added to R.
2. Rank the candidate set

Input: a query manuscript without citation placeholders
Output: where citation are needed a list of candidate article to be cited
Finding citation context: Divide the query manuscript into sentences- overlapping window of
100 word Extract citation context of corpus
▪ Language model▪ n-gram
▪ Contextual similarity▪ Topical relevance

The CBF module uses the text of the active paper as input and
the CF module uses the citations from the active paper as input.

Automatic a particular paper from the collection as a query and
its citations as the relevant documents.▪ Metrics: recall, precision, rank , coverage , co-cited
probability,
it is circular; system is attempting to improve the citing ability of authors, but evaluate with the papers that authors actually cite. ▪ System Might discover citations that are more relevant
than the one held out. Such citations may have not been included in the paper’s references list because of limits on space or because they overlapped with other references, possibly the one left out.
