For example, while identifying a phrase such as “Retinitis pigmentosa” is relatively straightforward for MAI software, words like “Sodium” are more complex – the relevant Subject Area term might be “Voltage-gated sodium channels”, any of several sodium compounds, or even just “Sodium” the element. The MAI process uses a Rulebase to guide term selection, disambiguating words and phrases based on context. The output ranks the matches by the number of times that terms appear in the text and selects the top eight terms for display. Machine Aided Indexing (MAI) is used to identify text strings in PLOS articles and match them to Subject Area terms from the PLOS thesaurus. For example, queries for “Blood cells” will return all articles indexed with the narrower term “White blood cells”. The next generation managers have allowed to have these applications on the web browser, which follows a logical, if the web browser is the natural tool for the discovery of scientific research, it is natural that this is the tool to collect bibliographic records, so that the web environment is becoming increasingly harder for a recurrent element share and discover scientific information. The hierarchical nature of the thesaurus allows search to retrieve all articles indexed with a specific Subject Area term and retrieve articles indexed with any term that sits deeper in the hierarchy. By contrast, performing an All fields search will return every article that contains even a single match to the term. Subject Area searches on the journal websites using the Subject field will return articles where the given Subject Area ranks highly enough to be included in the top eight retrieved terms. All terms track back to one or more of the top-tier terms, such as “Biology and life sciences” or “Social sciences.” For example the term “White blood cells” has two broader terms “Blood cells” and “Immune cells”. Subject Area terms relate to each other with a system of broader/narrower term relationships that form a polyhierarchy. Each article’s XML download provides the eight Subject Area terms listed on the article page and includes broader terms from all the paths leading back to these eight. Subsequently, clicking on a Subject Area term in an article returns a list of all articles related to that term.
The Subject Areas panel on each PLOS article displays eight terms selected from over 10,000 available. To report any incorrectly applied terms, click the target symbol next to the term on the article page, or email Subject Area terms Download current and previous versions of the thesaurus files here.
