Below we present basic features of the OMEGA-PSIR system.
Search features
Global Search Global search is usually the start page of the University Knoledge Base (UKB). It is used to comprehensively search over all object types at the same time (Everywhere option) or direct the query to a selected object type from the drop-down menu.
Type-oriented simple search For every record type the system provides a simple search form, sometimes also it provides advanced search form (see Advanced Search ).
Advanced search It allows one to adjust query details, and build an advanced query with logical operators, so that to obtain the most relevant results. In the case whe the MeSH based search is switched on, additionally it is possible to select pairs (descriptor + qualifier), so that a more accurate results can be obtained.

Search features
OMEGA-PSIR is equipped with very powerful seach capabilities, based on the SOLR technology. For each object type there is a screen with simple search (google-like), and advanced search. The index is built from metadata records and, whenever applicable, from the attached full text documents.
Objects in the Knowledge Base are connected to each other using various relationships, so that they create a semantic network, which can be see as a graph structure. Searching in the system can be performed in two ways (see Search Modes ):
by taking into account the graph structure and indicating in the query how particular types of objects should be combined - this is a graph search
by ignoring the graph structure and treating individual network elements as parts of a text document, for example, the text of the publication's description is "extended" by the text of the person's description, building a flat unstructured text which is indexed, so we perform a search in such extended unstructured texts - we then have a text search.
The search results can be adjusted to the user profile, so the answer can be built taking into account the researcher’s “fingerpring” of his/her research. What is very specific for the system, one can use the obtained answer for building a specific report (a simple bibliography listing, an advanced pivot table revealing knowledge hidden in the collected data, such as e.g. distribution of the research teams contribution to a given research subject).
Profiles
As OMEGA-PSIR covers functionality of Research Profiling, one of the main features of the system is automatic building various profiles, such as the profiles of researchers, and units constituting the formal hierarchical structure of the university.
The profiles characterize research achievements of the body, providing lists of publications, patents, promoted theses, activities, prizes and awards, bibliometric measures of the research, cooperation information and statistics. Once an achievement record of a researcher (publication, thesis, patent) is created (and/or deposited), it automatically appears in the profile of the researcher, and in the profile of his /her affiliation profile, as well as in the profiles on all the higher hierarchy levels. If the achievement has coathors, it also goes automatically to the coauthors and their afiliations profiles.
The entered achievements are used to automatically build a cloud of tags at researcher’s profiles and all the units profiles. The cloud of tags is a kind of “fingerprint” characterizing very precisely the research area of the researcher. In addition to the researchers and units profiles, one can define profiles for the main scientific disciplines that are practiced at the university. These profiles may go across the faculties and departments.
Statistics and reports
In OMEGA-PSIR statistics are everywhere. Various statistics are publicly available: some are available when you display a publication record where you can find altmetrics measures, or number of citations by Scopus or WoS; other aggregates can be found on the researchers profiles, or unit profiles, where one can also generate a ready-to-use report. The main idea is that having performed a search you can ”send” the answer to the system as an input and get a report generated as a result. The most powerful tool is a pivot table, it can be used in a flexible way to drill down into data to extract interesting trends; Other available tools, less dynamic, are predefined standard report for a periodical monitoring of the research.
Data management
In OMEGA-PSIR the data management facilities are very powerful. The system provides means for
importing data from various sources, both bibliographic and auxiliary ones (which makes the data entry process much cheaper). For example data can be imported from global scientific database, like e.g. SCOPUS, WoS, PubMed), from patents database (EPO), CrossRef, DataCite, ORCID, also from other OMEGA-PSIR based knowledge bases (which makes possible building the federated portals, see Polish Medical Platform);
enriching existing metadata with data from external resources (e.g. enriching bibliographic metadata with bibliometric data from Scopus, WoS, or integrating journals with Sherpa-Romeo to get information about openess strategy of the journals),
acquiring multimedia data from Youtube
importing XML files from web or from a desktop - special tools are available to translate XML to the requested formats.
Manual data entry by librarians and trained users
self depositing data by researchers
One can define workflow for data entry processes
Strong duplicate discovery procedures are available
For manual data entry staff strong validation control tools are provided. The validation procedures aredefinable by the system administration.
Roles and priviledges of the users
The system provides definable roles wchich then can be assigned to the system users. The roles specify which functions on particular objects are available. Additionally the system makes possible defining the scope of the access by assiging to the user a hierarchy level within the university structure, so that, for example, a given user is responsible for specific data type(s), but only for a given faculty.
Flexibility of the system
The system flexibility is the result of the applied architecture:
One can easily add new object types or change the structure of an existing one;
One can define ways of assessing research by means of scripts prepared in drools
one can define validation rules, data entry forms, search screens, etc
For the existing functions there is a toggle system, making it possible to switch on/off any function for all users, or only at the public level
