exaly is an academic search engine covering full-text of over 103 million scholarly articles, providing advanced search capabilities such as specifically finding keywords in figure captions and table cells of indexed articles. In addition to the search service, full scientometric data of articles, authors, and journals are provided. This is the only online service providing the historic impact factors of over 28,000 scholarly journals from 1665.[1]
exaly is a non-profit project and all its data and visualized graphics are freely available under the Creative Commons license.[2]
Overview[edit]
As claimed on the website, exaly has not yet received any public or corporate funds for its non-profit project, aiming to provide non-biased service to researchers in the absence of any commercial interest. The website openly allows access to the database on a large scale, as there is no limitation in pagination, and no registration is required for using the services.
Features and specifications[edit]
Search in Specific Fields[edit]
In addition to common fields such as title, abstract, and text, it is possible to search for a keyword in figure captions and table cells or in the combination of different fields.
Journal Impact Factors[edit]
exaly calculates the impact factors of all indexed journals from their inception by directly counting the citations. For the sake of consistency, the citable documents are based on CrossRef.[3] The impact factors are usually very similar to those released by Clarivate. However, there are major differences for some journals such as Nature and Science for which CrossRef mark most documents as the citable article. The graphs of impact factors (like all other graphs) are provided in editable SVG format. The version and the link to the updated version are noted on each graph.
Scientometric indices[edit]
exaly is a comprehensive resource of scientometric indices such as h-index, g-index, L-index, etc for both journals and authors.[4],[5] As amended on the original article that proposed L-index, exaly is the comprehensive resource for the L-index and percentiles of 3 million authors.[6]
Linguistic Analysis[edit]
Exaly has linguistically analyzed the text of over 100 million scholarly articles by breaking the sentences into grammatical elements (verbs, objects, adjectives, and adverbs) via Subject–verb–object word order.[2] The data are provided for 4.9 million authors, revealing their writing styles. In addition to helping in enhancing their vocabulary, this can be used to identify plagiarism.
Finding Journals[edit]
It is possible to find the most popular journals for a given keyword(s), as the search returns a list of journals with the highest number of articles containing the given keyword(s).[1]
Finding Authors[edit]
Similarly, it is possible to search for authors with a specific keyword(s). The list of matching authors is listed by the number of publications relating to the searched keyword(s).[1]
Article Citations[edit]
The pattern of citations for each article is provided by graphs showing the emergence and disappearance of citations for an article.
Open Access Articles[edit]
Among the indexed articles, there are over 22 million Open Access or free articles for which the search results directly redirect to the article PDF at the publisher's website. This makes exaly a comprehensive database of Open Access articles.
Author Citation Rankings[edit]
The most cited authors of each journal have been identified not only for the lifetime but also for each year.
