Calculate biomarker scores for abstracts
Description
Calculate biomarker score for each abstract to indicate possible use of miRNAs as biomarker.
Usage
calculate_score_biomarker(
df,
keywords = biomarker_keywords,
case = FALSE,
threshold = NULL,
indicate = FALSE,
discard = FALSE,
col.abstract = Abstract
)
Arguments
df |
Data frame containing abstracts. |
keywords |
Character vector. Vector containing keywords. The score is
calculated based on these keywords. How much weight a keyword in |
case |
Boolean. If |
threshold |
Integer. Optional. Threshold to decide if use of miRNAs as
biomarker are present in an abstract or not. If |
indicate |
Boolean. If |
discard |
Boolean. If |
col.abstract |
Symbol. Column containing abstracts. |
Details
Calculate biomarker score for each abstract to indicate possible
use of miRNAs as biomarker. This score is added to the data frame as an additional
column Biomarker_score
, containing the calculated biomarker score.
To decide which abstracts are considered to contain use of miRNAs as biomarker, a threshold
can be set via the threshold
argument. Furthermore, an additional
column can be added, verbally indicating the general use of miRNAs as biomarker in
an abstract.
Choosing the right threshold can be facilitated using plot_score_biomarker()
.
Value
Data frame with calculated biomarker scores.
If discard = FALSE
, adds extra columns
to the original data frame with calculated biomarker scores.
If discard = TRUE
, only abstracts are with miRNAs as biomarker
are kept.
