The global interpretation assumes that there exist some fixed set of underlying topics derived from inter-document similarity. These global clusters or their representatives can then be used to relate relevance of two documents (e.g. two documents in the same cluster should both be relevant to the same request).
Relevance is the connection between topics that makes one useful for dealing with the other. Relevance is studied in many different fields, including cognitive science, logic, and library and information science .
For example, a paper reviewing existing research, a review article, monograph, or textbook is often better than a primary research paper. When relying on primary sources, extreme caution is advised. Wikipedians should never interpret the content of primary sources for themselves (see Wikipedia:No original research and Wikipedia:Neutral point of ...
Research in the humanities involves different methods such as for example hermeneutics and semiotics.

Meta-analysis is a method of synthesis of quantitative data from multiple independent studies addressing a common research question.

As such, this statistical approach involves extracting effect sizes and variance measures from various studies ...

[1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
Wikipedia, like other encyclopedias, is intended to provide an overview of topics and indicate sources of more extensive and academic information. Many of the general rules of thumb for conducting research apply to Wikipedia, including:
Choosing a research question is an essential element of both quantitative and qualitative research. Investigation will require data collection and analysis, and the methodology for this will vary widely. Good research questions seek to improve knowledge on an important topic, and are usually narrow and specific. [1]
