User-Centric Process of Designing a Molecular & Cellular Query Interface for Biomedical Research

There is a growing demand for the adoption of user-centric design processes for the development of computational biology software as usability becomes a major concern. Our team develops interfaces for a human biomolecular data portal with user-centered design, so we present a case study of the design process of a molecular and cellular query to emphasize the importance of user-centric design and reveal the complications that arise in a complex software development environment. The study follows the design process from user requirement gathering to the prototyping of a minimum viable product.

DatumKB: A Database of Biological Experimental Results

DatumKB is a freely accessible database of experimental results involving the function and regulation of human proteins in cultured cells. The results are manually curated from biological research literature using a shorthand language and stored as datums. Datums were originally designed to be used as evidence for rules in a Pathway Logic model of intracellular signal transduction (STM8, http:// pl.csl.sri.com/online.html) (1). They are independent units that can be understood by biologists, traced back to their source, and have enough structure to be interrogated computationally. The information is expressed using a controlled vocabulary with links to well known databases such as HUGO Gene Nomenclature Committee (HGNC), UniProt, PubChem, and Cellosaurus. DatumKB can be searched using a query interface and the results can be downloaded in the original datum format, a simplified text format, or a JSON file. Links to detailed documentation of datum structure and a tutorial for the search engine are provided.

UniBioDicts: Unified access to Biological Dictionaries

Summary We present a set of software packages that provide uniform access to diverse biological vocabulary resources that are instrumental for current biocuration efforts and tools. The Unified Biological Dictionaries (UniBioDicts or UBDs) provide a single query-interface for accessing the online API services of leading biological data providers. Given a search string, UBDs return a list of matching term, identifier and metadata units from databases (e.g. UniProt), controlled vocabularies (e.g. PSI-MI) and ontologies (e.g. GO, via BioPortal). This functionality can be connected to input fields (user-interface components) that offer autocomplete lookup for these dictionaries. UBDs create a unified gateway for accessing life science concepts, helping curators find annotation terms across resources (based on descriptive metadata and unambiguous identifiers), and helping data users search and retrieve the right query terms. Availability and implementation The UBDs are available through npm and the code is available in the GitHub organisation UniBioDicts (https://github.com/UniBioDicts) under the Affero GPL license. Supplementary information Supplementary data are available at Bioinformatics online.

This can be coupled to for instance the ‘vsm-autocomplete’ module: an input field (user-interface component) that offers autocomplete lookup for these dictionaries. UBDs create a unified gateway for accessing life science concepts, helping curators find annotation terms across resources (based on descriptive metadata and unambiguous identifiers), and data users search and retrieve the right query terms.
