Structured digital abstract
Encyclopedia
A Structured Digital Abstract (SDA) is a method of describing relationships between biological entities in a structured, but human-readable, format. It is added below the abstract of scientific articles published in FEBS Letters

History

Many scientific manuscripts describe relationships between entities such as genes
Gênes
Gênes is the name of a département of the First French Empire in present Italy, named after the city of Genoa. It was formed in 1805, when Napoleon Bonaparte occupied the Republic of Genoa. Its capital was Genoa, and it was divided in the arrondissements of Genoa, Bobbio, Novi Ligure, Tortona and...

 began publishing manuscripts with “structured digital abstracts” (SDAs). The SDAs were added to the end of abstracts in a structured, but human-readable, format and digitally linked to interaction databases. In the pilot project, the journal concentrated on protein-protein interactions. After six months, this “experiment” was evaluated. As it was a success, all appropriate FEBS Letters

 challenges have focused on protein-protein interaction
Protein-protein interaction
Protein–protein interactions occur when two or more proteins bind together, often to carry out their biological function. Many of the most important molecular processes in the cell such as DNA replication are carried out by large molecular machines that are built from a large number of protein...

Text mining
Text mining, sometimes alternately referred to as text data mining, roughly equivalent to text analytics, refers to the process of deriving high-quality information from text. High-quality information is typically derived through the devising of patterns and trends through means such as...

An SDA comprises a series of sentences each of which contains a relationship between two biological entities, mentioning the method used to study the relationship. To provide a simplified example: protein
Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

 B, by method X. Each sentence in an SDA is followed by one or more identifiers pointing to the corresponding database entries that contain all the details of the structured information. Although most of the sentences currently point to the MINT Molecular INTeraction Database, the proposed structure can easily be extended to contain identifiers from other databases storing protein interactions or different types of relationships between biological entities. Each entity is also linked to the appropriate explanatory database. e.g. UniProtKB for proteins and the European Bioinformatics Institute
