The PolyU Institutional Research Archive (PIRA) is an online platform that collects and disseminates the research and scholarly outputs created by the PolyU community. By showcasing the publications, research interests, activities and academic achievement of PolyU scholars, the PIRA aims to increase the visibility of the University’s research and facilitate knowledge transfer.

Search Tips

What is not searched - Stop Words

The search engine ignores certain words that occur frequently in English, but do not add value to the search. These are: "a", "and" , "are" , "as" , "at" , "be" , "but" , "by" , "for" , "if" , "in" , "into","is" ,"it" ,"no" , "not" , "of" , "on" , "or" , "such", "the" , "to" , "was"


Use an asterisk (*) after a word stem to get all hits with words starting with that root, for example:

select * will retrieve selects, selector, selectman, selecting.


The search engine automatically expands words with common endings to include plurals, past tenses ...etc.

Phrase Searching

To search using multiple words as a phrase, put quotation marks (") around the phrase.

"organizational change"

Exact word match

Put a plus (+) sign before a word if it MUST appear in the search result. For instance, in the following search the word "training" is optional, but the word "dog" must be in the result.

+dog training

Eliminate items with unwanted words

Put a minus (-) sign before a word if it should not appear in the search results. Alternatively, you can use NOT. This can limit your search to eliminate unwanted hits. For instance, in the search

training -cat or training NOT cat

you will get items containing the word "training", except those that also contain the word "cat".

Boolean searching

The following Boolean operators can be used to combine terms. Note that they must be CAPITALIZED !

AND - to limit searches to find items containing all words or phrases combined with this operator

e.g.cats AND dogs will retrieve all items that contain BOTH the words "cats" and "dogs".

OR - to enlarge searches to find items containing any of the words or phrases surrounding this operator

e.g.cats OR dogs will retrieve all items that contain BOTH the words "cats" and "dogs".

NOT - to exclude items containing the word following this operator NOT cat will retrieve all items that contain the word "training" EXCEPT those also containing the word "cat"

Parentheses can be used in the search query to group search terms into sets, and operators can then be applied to the whole set

e.g.(cats OR dogs) AND (training OR discipline)

Researcher Profile

The PIRA Researcher Profile Pages have been available since spring 2015. Researcher Profiles include useful information about individual academics such as their research interests and outputs as well as other measures of their achievements.

Personal Details

Data for our Researcher Profiles are sourced from departmental pages and the PolyU Experts Directory

Researchers and academic staff are welcomed to add additional information to enrich their personal profiles. See Managing your profile

Author Identifications

A unique author identifier is a tool that can help to identify researchers and their publications. Your author identifier enables you to control your profile and overcomes issues associated with variations of name spellings or institutions. Below are the author identifiers that are collected in the PIRA:

ORCID - ORCID (Open Researcher and Contributor Identifier) is a registry of unique identifiers for researchers and scholars. It helps to promote the discoverability of publications across multiple platforms and establishes a unique presence for researchers regardless of name variants or affiliation history.

Scopus Author ID - is automatically assigned by matching variations of an author’s name to locate and verify a particular author’s research output in the Scopus citation database.

ResearcherID - researchers can register for a unique researcher ID number which is developed by Thomson Reuters and used in Web of Science. Researchers can update their profile information, build their publication list, and select to make their profile public or private. At Researcher ID, mouse over “R” badge, information about the researcher is displayed in a popup window. The popup window will show the researcher's name, ResearcherID, up to 3 of his/her most recent publications (from the researcher's ResearcherID publication list), and a link to that researcher's ResearcherID profile page.

Google Scholar Citations - researchers can create a profile easily. It provides a way for authors to keep track of citations to their articles, obtain up to date citation metrics and graph. Make your profile public, so that it appears in Google Scholar results when people search for your name.

Research Outputs

Publication data shown on Researcher Profiles is mainly sourced from PolyU Research Output System (ROS). Other sources include Web of Science, Scopus, and PubMed Central etc.

Adding Publications

To add materials to PIRA, use any one of the following channels:

Making your work open access

Researchers and academic staff are encouraged to submit the full-text version of their research outputs through ROS. During submission, the ROS will ask for the author’s permission to post to the PIRA, and for a soft copy of the author’s manuscript. PIRA staff will review each full-text deposit submitted before publishing the material online. The PIRA will store the file in the repository and make it public only if copyright or publisher archiving policies permit. If relevant permissions cannot be obtained, only citation data will be posted.

Version to use

You should deposit the version that complies with publisher copyright policies. This is usually the accepted author’s final version (postprint), including modifications based on referees' suggestions but before the publisher’s copy editing and formatting.

Open Access at PolyU

PolyU has adopted the following Policy in Support of Open Access to Published Research since September 2010: PolyU academic and researchers are required to deposit electronic copies of their peer-reviewed journal articles and conference proceedings (author’s final accepted manuscript) in PolyU IR (now known as PIRA) for open access, as of the date of paper publication. Full text of other research outputs should also be deposited where appropriate. The Library will determine whether deposit in institutional repositories for public access is permitted under publisher agreements when PolyU authors submit their scholarly output to the PIRA. For more information, see Research Office webpage on the Policy
