cBioPortal allows the analysis and visualization of published cancer genomic datasets. These datasets must be queried by entering symbols of genes of interest. "OQL" keywords can also be added to further refine the query.
My project focuses on improving the querying experience on cBioPortal. This is done by giving users visual feedback regarding the correctness of the symbols that they have entered. For incorrect symbols, similarly-spelled valid symbols are provided as suggestions. This is useful when a user has misspelled a gene symbol, or has entered an incomplete/ambiguous symbol. Furthermore, when a user wants to enter OQL keywords, a multi-level prompt menu is provided where a user can choose keywords and see a description of what they mean. Upon selecting it, the keyword is added to their query.
